This manual reflects the software capabilities in version

3.0 software.

We have attempted to take care and develop manuals which provide in-depth information. Where possible, we have attempted not only to describe what you see on the screen, but how to understand and use it as well.

Obviously, we can’t teach you how to navigate, but we can help make your work more thorough and enjoyable.

Throughout the manual, you will find helpful hints about the interaction of various functions. In a piece of equipment that has the many capabilities of this receiver, important details can sometimes become obscured in one or two lines of text. In our effort to ensure you get the most out of this documentation, and to protect against important details becoming lost, don’t be surprised if you see the same or similar information more than once.

This manual is organized by describing first the MX500 model covered in this book. Then the special front panel features including the traffic light indicator and USB connector. The sections that follow detail each primary function as it is presented on the front panel (i.e. NAV,

RTE, WPT, PLOT, ...CFG). The appedixes describe important details about special functions and installation of the

MX500.

We hope you find the manual enjoyable and informative reading. As always, we welcome your comments on improving our products or manuals. We wouldn’t mind if you wrote to tell us that we did the job right the first time either. You can find a Reader Comment Card at the back of the manual.

About GPS Navigation

This GPS receiver is a precision navigation instrument utilizing the latest technology available today to provide optimum performance from the GPS satellite and Beacon land signals received. As with all other forms of radio signals, the ultimate navigation result is dependent upon the quality of these signals. Radio signals may, on occasion, be distorted, jammed, or otherwise incorrect. As a result, your position accuracy may occasionally be less than that which can normally be expected.

The Navstar Global Positioning System, commonly referred to as GPS, is a satel lite navigation system developed by the U.S. Department of Defense to provide both military and civilian users with highly accurate, worldwide, three dimensional navigation and time. By receiving signals from orbiting GPS satellites, authorized users are able to continuously navigate with an accuracy on the order of 5 meters 2D RMS or better

A technique referred to as Differential GPS (DGPS), allows users to obtain maximum accuracy from the GPS system. DGPS requires the use of two GPS receivers.

One receiver, known as the Reference Station, is placed at a surveyed location, the coordinates of which are precisely known. The purpose of the differential GPS system is to use the reference station to measure the errors in the GPS signals and to compute corrections to remove the errors. The corrections are then communicated in real-time to the navigators, where they are combined with the satellite signals received by the navigators, thereby improving their navigation or positioning. The geographic validity of these corrections decreases with distance from the reference station, but the corrections are valid for navigators hundreds of kilometers from the reference station.

Marine radio beacons operating in the 283.5 to 325.0 KHz frequency range are in widespread use for direction finding in coastal navigation. Because the beacon system has been in place and widely used for many years, it provides an effective means for the transmission of DGPS signals.

Depending on their local environment and power output, their signals may be usable to several hundred miles.

Marine beacons provide an economical means of obtaining DGPS accuracy for coastal navigators. GPS receivers

10 | Simrad MX500

with built-in beacon receivers are designed to provide low cost reception of DGPS corrections broadcast (normally free of charge) by coastal authorities.

Special Notes

GPS

Never rely solely on any single navigational aid. Always use whatever information is available, and cross-check information when possible. GPS expected position accuracy is dependent upon multipath environment, number of satellites in view, baseline length (for local services), ionospheric activity, and HDOP. The derived speed and course readings may be hampered accordingly. The GPS system was declared operational in 1994; however, the system’s availability and accuracy are subject to change at the discretion of the U.S. Department of Defense.

DGPS

This GPS receiver’s position accuracy is dependent upon ionospheric activity, multipath, subject to the availability, accuracy, and control of the DGPS correction transmission from the Beacon Station.

The beacon radio signal which carries the DGPS corrections may be hampered by weather conditions such as heavy rain, snow, and thunder storms. The beacon radio signal may also be interrupted by powerful radio transmitters operating in long wavelength bands.

Charts and Navigational Aids

Positions obtained from charts are not always as accurate as your navigator (due to environmental changes, the dates of charts, and datum offsets if the datum differs from the one in use by the navigator). The position of a floating aid can differ due to tide, set and drift.

MX500 USB Feature Overview

USB stands for Universal Serial Bus, and is a data port in the MX500 that allows the use of USB flash drive

(memory stick) to save and restore waypoints, routes and configuration data. In addition it can also be used to download the MX500 firmware for software updates. Not all commercially available USB flash drives are compatible with the MX500.

USB Formatting:

Before the USB device (i.e. flash drive) can be used for the MX500, it is important to format it to FAT32 file system. This is available from any PC running Windows XP or higher.

USB Waterproofing:

When the USB port in the MX500 is not in use, please close the rubber flap in order to maintain splashproof integrity.

Do not remove the USB rubber flap completely from the MX500 unit. This will affect the splashproof integrity.

MX500 Networking Overview

The MX500 networking technology lets you connect two or more MX500 units in Dual-Control or Multiple Unit

Control configuration via LAN (Local Area Networking) in order to share navigation data among the units. A change to routes and waypoints in the master or in a slave unit is mirrored on all the networked units.

One MX500 is designated as the master and all others as slaves or repeaters. The only restrictions on the networking are the following:

• There must be one and only one master unit operating in a network.

All MX500 units must have the same software version.

12 | Simrad MX500

Network Cables & Waterproofing:

If all components are located in dry areas and do not require waterproof cables and connectors, standard offthe-shelf Ethernet cables can be used. These cables are available in a variety of lengths and can be obtained from sources that carry computer networking supplies. The installer should ensure that the cable is category 5 (CAT5) or category 5e (CAT5e) cable. Other cables, particularly voice grade cables, look very similar but will not work as part of the MX500 network system.

Any connector exposed to the weather or possibility of exposure need to be waterproof. Cables can be ordered from SIMRAD with waterproof connectors installed on both ends. Cables are also available with a waterproof connector on one end and a non-waterproof connector on the other end.

The simplest way to interconnect a network consisting of just two MX500 units (Dual Control configuration) is to use an Ethernet cross-over (null) cable. A cross-over cable eliminates the need for an Ethernet switch.

When more than two MX500 units (Multiple Unit Control configuration) are being connected, or if you wish to leave room for future expansion, use an Ethernet switch that serves as a common connection point for all the units. Do not use cross-over cables with an

Ethernet switch.

The table 1a below shows all the waterproof network cables that SIMRAD offers for the MX500.

Ethernet Switches:

Ethernet switches allow for the interconnection of more than two MX500 units. Each MX500 can exchange data with any other MX500 connected to the switch.

For non-waterproof switches, any standard 10/100 Mbit

Ethernet switch can be used. These devices generally come with a power adapter which is plugged into a

110VAC (or 220VAC) power outlet.

Fully waterproof, 10-32VDC powered switches are available from Woodhead Connectivity Ltd.

This is an enhanced Dual-Control configuration wherein two MX500 CDUs and two smart DGPS antennas are supplied. The two MX500 units are connected in dual-control configuration but they operate as independent navigator units with dedicated antennas. The Dual Control Integrity

Monitoring (IM) feature is a software option that works in the MX500 CDU hardware.

This configuration allows data to be shared between two remotely separated stations (i.e. navigator’s station and helmsman’s station), with independent access to various information fields. The purpose of this configuration is to enable each CDU to calculate its own position, then check the operational status of the other GPS receiver.

The GPS receiver with the best overall operational status then provides the system position. This provides a fully redundant system, with self-recovery capabilities.

DGPS Beacon System

As Maritime Safety Administrations, Navy, and Coast

Guard Organizations realize the limitations of standard

GPS positioning, many have begun installing DGPS

Beacon Stations. While an understanding of this system is not necessary for operating receivers with internal beacon receivers, you may want to read on to have a better understanding of how your receiver is capable of achieving the high levels of accuracy made possible by this network of transmitters.

The DGPS Beacon System is comprised of three segments: the reference station, Integrity Monitor (IM) equipment located at the beacon site, and the Navigator equipment located on board the user’s boat or vehicle.

The DGPS beacon system design is illustrated below.

Differential GPS Traffic Light Operation:

Red Flashing

Not tracking satellites (no position update). This is normal for the first 2 minutes or so when turning the unit on. The very first time you turn the unit on, or if the memory is reset or lost, this condition is also normal. Allow the receiver to run for at least 30 minutes under these circumstances. If it still does not change to Red Solid, refer to the troubleshooting section in the

Installation section of this manual.

Red/Yellow Solid

Dead Reckoning. When normal GPS or DGPS operation is not available, this LED sequence is provided to quickly identify the DR navigation mode. A DR indicator is also displayed on all screens.

Red Solid

Tracking one or more satellites (no position up-

date). This is also normal for the first 2 minutes or so when turning the unit on. The very first time you turn the unit on, allow the receiver to run for at least 20 minutes after changing to Red Solid to collect an almanac from the satellites, regardless of whether a position update has been calculated or not. This is also a normal indication if the HDOP is greater than 10, if the receiver is tracking too few satellites, or for other reasons as well.

Read the GPS and DGPS function screens for more information.

Yellow/Green Solid

GPS position update; DGPS corrections are not be-

ing received. You may see this from time to time during normal operation. It usually occurs when the beacon signal is not available (either it is being blocked by terrain or a local object or you are out of range of the transmitter) and/or you are tracking 3, 4, or 5 satellites, and the satellites have poor geometry relative to your position.

The condition will normally go back to green solid, when it picks up another beacon station. The factory default

Simrad MX500 | 21

level for dropping DGPS corrections is 600 seconds.

During this period, your positioning information is less than optimal, and position accuracy may be off by as much as 3 to 5 meters. Press the GPS function key and refer to the DGPS section in this manual for guidance if this light condition occurs.

Yellow Solid

DGPS position update with poor HDOP value. You may see this from time to time during normal operation. It usually occurs when you are tracking 3, 4, or 5 satellites, and the satellites have poor geometry relative to your position. The condition will normally go back to Green Solid when it picks up another satellite or the geometry of the existing satellites improves. The factory default level for this indication is with an HDOP of 4 to 10. During this period, your positioning information is less than optimal, and position accuracy may be off by as much as 5 to 10 meters. You can press the GPS function key and refer to the GPS section in this manual for guidance if this light condition occurs.

Green Solid

DGPS position update with HDOP value less than 4.

This is the normal operating condition. Position accuracy is normally better than 3 meters. Keep in mind that position accuracy is always only as good as the corrections received, their age, your distance from the reference station, and the geometry of the satellites. This is the normal operating condition and no icon will be displayed.

GPS Traffic Light Operation:

Red Flashing

Not tracking satellites (no position update). This is normal for the first 2 minutes or so when turning the unit on. The very first time you turn the unit on, or if the memory is reset or lost, this condition is also normal. Allow the receiver to run for at least 30 minutes under these circumstances. If it still does not change to Red Solid, refer to the troubleshooting section in the

Installation section of this manual.

Red/Yellow Solid

Dead Reckoning . When normal GPS or DGPS operation is not available, this LED sequence is provided to quickly identify the DR navigation mode. A DR indicator is also displayed on all screens in the upper left hand corner of the display.

Red Solid

Tracking one or more satellites (no position up-

date). This is also normal for the first 2 minutes or so when turning the unit on. The very first time you turn the unit on, allow the receiver to run for at least 20 minutes after changing to Red Solid to collect an almanac from the satellites, regardless of whether a position update has been calculated or not. This is also a normal indication if the HDOP is greater than 10, if the receiver is tracking too few satellites, or for other reasons as well.

Read the GPS and DGPS function screens for more information.

Yellow Solid

GPS position update has a poor HDOP value. You may see this from time to time during normal operation.

It usually occurs when you are tracking 3, 4, or 5 satellites, and the satellites have poor geometry relative to your position. If you are patient, the condition will normally go back to Green Solid when you pick up another satellite or the geometry of the existing satellites improves. The factory default level for this indication is with an HDOP of 4 to 10. During this period, your positioning information is less than optimal, and position accuracy may be off by as much as 10 to 30 meters. You can press the GPS function key and refer to the GPS section in this manual for guidance if this light condition occurs.

Green Solid

GPS position update with HDOP value less than 4.

This is the normal operating condition. Position accuracy is normally between 3 to 5 meters, but can be out as much as 30 meters. Keep in mind that position accuracy is always only as good as the geometry of the satellites and the navigation information provided by the satellites.

Simrad MX500 | 23

This is the normal operating condition and no icon will be displayed.

The Display:

The CDU uses a Transflective LCD display screen. It provides optimum viewing in virtually all lighting conditions. To change the display contrast or backlight condition, select the CFG function key and scroll down to the

Lighting menu choice. Refer to the CFG section of the manual for a complete description of menu options. The

Power On/Off/Lighting triple function key allows you to quickly change between daytime and night time screen settings, and turn On or Off the unit.

Information displayed on the screen is normally divided into windows, similar to what you might see on a normal computer. Each screen has a page number in the upper left hand corner. These page numbers are there to help you quickly find the information you need, and to help us guide you on the rare occasion that you might request our assistance.

With the exception of a portion of the PLOT and MOB screens which use the UP and DOWN arrows to change the view scale, all of the screens require that you press the EDIT (Edit Mode) function key before you are allowed to change data on the screen. You can use the cursor key

(the big key with the arrows pointing in four directions) to move between edit fields or menu choices on most screens when in the edit mode. When you are not in the edit mode, you can use the cursor to scroll between screens (i.e. NAV1, NAV2, NAV3, ...) or to move up and down on screens (like the menu bar in the CFG screen).

+ Virtual Softkeys:

This function key activates or deactivates the softkeys and edit fields within any screen where editing is appropriate. You will quickly learn that this is an important operating feature in the unit. Press the EDIT key when you want to start editing a screen and again when you have

24 | Simrad MX500

finished editing. If after editing you press a function key and nothing seems to happen, check to make sure you didn’t accidentally alter your information and press the

EDIT key to end editing. Some edit screens provide an

Escape softkey. If you decide for some reason that you don’t want to use the changes you have made, pressing the Escape softkey will restore the original information.

However, once you press the EDIT key, all changes are accepted and the original data is lost.

The virtual softkeys under the bottom of the display are so named because their purpose changes from one menu or screen to the next. All of the screens require that you press the EDIT (Edit Mode) function key before the virtual softkeys can be accessed. Then use the LEFT and RIGHT cursor arrows to highlight the desired virtual softkey and press the ENT key to choose it. Don’t forget to press the EDIT function key when you have finished editing a screen.

The Function Keys:

The Function Keys are the keys to the right of the display.

There are 16 function keys in all. Eleven of the function keys access various screen and editing displays. Three of these function keys are used for editing or moving within the screens. One function key is used to mark your present position, and to activate/deactivate Man Over Board alarms when depresses for a few seconds. One is used as the power on/off key, and switches between two display lighting options when depresses for a few seconds.

The ten function keys with alpha abbreviations on them are described in the ensuing chapters. The five function keys with symbols and the GOTO key are described below.

The function keys are also used in the edit mode to enter alphanumeric information into screen data fields.

Simrad MX500 | 25

Mark Position/MAN OVER BOARD

(MOB) Key

This dual function key stores your present position, date and time at the next available waypoint location in the waypoint bank. A window pops up on the screen to confirm your key depression, and to tell you where the mark position is being stored. You can go into the WPT menu and edit the coordinates or description later. The CDU is also capable of performing this function from a remote contact closure input via AUX Cable (MOB/Event) wire.

Refer to the Installation section of this manual for interface instructions.

When depressed for 3 seconds, this function key activates a number of automatic functions:

► Most obviously, it brings up an MOB1 (Plot) screen.

This is an automatic scaling screen which selects the best zoom level to display your present position and the

MOB position. In addition, the MOB position is displayed in the upper left corner, so that you can quickly read the coordinates to others who may be available to render assistance. This plot screen also provides the vital bearing and distance back to the MOB position, as well as your present course over ground.

► The MOB position, date and time are stored in the

Waypoint Bank for future reference (e.g. log book entries).

► Navigation data output on the NMEA ports (i.e. BWC and BWR), are changed to reflect the current crisis situation. This way, other interfaced equipment can also help guide you back to the MOB position. When the MOB condition is canceled via a MOB screen softkey, the NMEA sentences will automatically revert to the active route information. Don’t forget to cancel the MOB so your inter- faced equipment will read the correct data.

► The MOB function key and remote MOB input are disabled from subsequent activation, until the MOB Cancel softkey is selected.

► Other functions such as Position and Navigate can still be accessed; however, the screen will revert to the MOB

Plot screen after 30 seconds. Bearing and distance infor-

26 | Simrad MX500

mation in these other screens relate to the MOB position, not the next waypoint in the active route, until MOB is canceled.

To cancel a MOB condition, make sure you are in the MOB

Plot screen. Press the EDIT function key, then select the

Cancel MOB softkey.

The MX500 is also capable of performing the MOB function from a remote contact closure. If the contact closure is made for 1 second, the input is registered as a Mark

Position. If the contact closure is made for 3 seconds, the input is registered as a MOB Position. Refer to the

Installation Section of this manual for interface instructions.

GOTO

This function key allows you to quickly create a route from your present position to waypoint or a route. This single waypoint route can use an existing waypoint from the Waypoint Bank, or you can quickly create one by either defining the appropriate coordinates or specifying a range and bearing.

Be careful when you use this selection, as it will erase your current active route when it creates the new one.

Read through the ROUTE and PLOT sections of this manual to find other ways to use this key within an active route.

POWER ON/OFF & LIGHT

This triple function key turns the unit on and off. When depressed while the unit is on, you will be prompted to select a YES or NO softkey to confirm your action. This is known as a software power off.

If the operating program should hang up for any reason, you can also perform a hardware power off by continuing to depress the power on/off function key for about 5 sec-

Simrad MX500 | 27

onds. When the GPS is turned off using this technique, you can not reapply power for 10 seconds.

An occasion may arise when you need to reset the memory back to the factory default values. Doing this will cause the CDU to lose all of your defined settings, as well as all 2,000 of your waypoints and routes. If you hold down the “CLR” button when power is applied for about six seconds, then the memory will be cleared.

When depressed for 3 seconds, this triple function key allows you to quickly switch between two predetermined display lighting conditions, a daytime/night time setting. Select the CFG function key and scroll down to the

Lighting menu choice to make the desired adjustments.

Refer to the Configuration section of the manual for a complete description of the Lighting menu options.

CLR

CLR (CLEAR)

This function key is probably the least used of all the function keys; however, it can save you some otherwise frustrating editing time. This key allows you to erase or clear one character at a time. If you hold it down, it will erase the entire line that the cursor is currently on.

CURSOR

This function key is the most used of all the function keys. When pressing the EDIT key to activate the virtual softkeys, the LEFT or RIGHT arrow cursor keys are used to scroll left or right from one softkey to the next. It also allows you to move between function screen pages (by pressing left or right). In addition, many of the edit fields allow you to use either the cursor key or the Change softkey to scroll through or select from predetermined choices.

ENTER

This key is often used just like the EDIT and the CURSOR

28 | Simrad MX500

keys. When pressing the EDIT key to activate the softkeys, the ENT key is used to select the particular virtual softkey of user’s choice.

FUNCTION

You might have noticed that above and below each primary function key there are numbers and letters. These numbers and letters are used when you are in the edit mode. You will find that they are most often used in the

RTE, WPT, and CFG screens, but they are used in other screens as well. If you are trying to enter text, simply locate the desired letter and press the appropriate function key repeatedly until the appropriate letter or number appears. If you accidentally go past the desired letter, repeat pressing the function key and the letter will come up again. You can toggle between upper and lower case characters by pressing the function key for a long period.

You will also find that some screens allow you to input symbols into the text fields. These symbols are selected through a softkey selection where symbols are allowed.

Don’t forget to press the ‘EDIT’ key to get out of the edit mode!

Another helpful feature on this CDU is that successive depressions on the function key (when not in the edit mode) allow you to page through all of the screens available for that particular function. You can accomplish the same thing by selecting a function and using the left and right arrows on the cursor key (which is sometimes faster). In addition, the software remembers which screen you used last for each function. Each time you reenter a function (e.g. you go from PLOT to NAV), you will enter the last screen you viewed for that function. You can change this setting in the CFG 1 Operation.

Use the associated function key to access the international character desired (i.e. A for Æ). The international characters supported are:

ABC = Ä, Å, Æ, À, Ç

DEF = É, È

GHI = Í

MNO = Ñ, Ó, Ö

STU = Ú, Ü

Navigate

There are six basic NAV screens. NAV4, NAV5, and

NAV6 only provides data if appropriate sensors (e.g. wind speed/direction logs, NMEA compass, etc.) are interfaced and activated on the CDU. The NAV functions are highly interactive with the RTE1 screen, and a number of CFG menu selections.

The RTE1 screen provides the active route for the NAV screens. It also maintains a waypoint pass log for you.

One other important feature in the RTE1 screen that you need to be aware of is that the up and down arrow softkeys control which waypoints are skipped (down arrow) and which are restored (up arrow) for your current route. The ETA information is configured in the RTE 1 screen. Refer to the Route section of the manual for a full description.

The following CFG menus directly impact the NAV functions:

• COG SOG - sets the filtering time for the displayed values.

30 | Simrad MX500

Datum - sets the reference datum for your present position and waypoints in the active route.

GPS Offset - sets an offset for calculating the GPS antenna position if you can’t physically locate the antenna exactly where you want it (e.g. over the centerline of the boat).

-

-

-

-

Navigation - sets a variety of important functions and alarms

Rhumb line or Great Circle navigation

Range units: nautical miles, nautical miles and meters (when under 1000 meters), nautical miles and feet (when under 1000 feet), statute miles, statute miles and meters (when under 1000 meters), statute miles and feet (when under 1000 feet), kilometers, or kilometers and meters (when under

1000 meters)

Cross-track error limit and alarm control

Waypoint pass criterion and distance: bisector line, perpendicular line, complex (combination of bisector line and perpendicular line), distance to waypoint, or manual

Waypoint Approach distance

Autopilot alarm control

Position - sets to either Lat/Lon or UTM, and some alarm limits. There is an optional software package available to setup a user grid as well. The option is explained in the Position, and CFG Position sections of this manual.

Time - sets appropriate offsets, and 12 or 24 hour clock mode.

Various NMEA input controls for sensors (i.e. speed log, wind instruments, etc).

Simrad MX500 | 31

You have probably already figured out that you will need to pay close attention to the configuration screens. The good news is that you should only have to setup one time. Keep in mind, though, that you may need to revisit these and other configuration screens from time to time to get the CDU to do exactly what you want it to.

Dead Reckoning

The MX500 CDU is capable of Dead Reckoning (DR) calculation when appropriate compass/heading and speed log sensors are connected and activated. Refer to the

NAV4 and CFG sections of this document.

When the CDU is in the DR mode a DR icon is displayed in the upper right corner of the screen.

NAV1 - The Panorama Screen

This screen is designed to give you a unique 3 dimensional look at the active route you are to follow. It is typically referred to as a runway view because you can see navigation markers, your course line, the cross-track error lines, and waypoint flags as you pass them. Take a look at the example below.

If you don’t see the information described in this screen, you will need to create a route in RTE1 first.

The somewhat triangular shape at the bottom center of the screen represents the bow of the boat. Icons on the screen are always related to this object. The two dash lines extending from the bottom of the screen towards the center of the screen represent your cross-track error limits. The dotted line extending from the bow of the boat icon represents your course line. The course

32 | Simrad MX500

line changes direction at the flags, which represent your waypoints, and continues through to the end of the active route you entered in RTE1. Notice that the crosstrack error lines end at the first flag. As you pass the flag and start the next leg of your course, these lines will be redrawn to reflect the course change. Icons that you see left and right of your course are navigation markers that you define in the Waypoint Bank (WPT1) where a symbol is used as the first character of the waypoint description. The Panorama and Plot screens will automatically place these navigation markers on the screen as you approach them.

The degree values that you see are your Course Over

Ground (COG), as calculated by the GPS receiver’s position fix to position fix, and Bearing (BRG) from your present position to the waypoint. The speed value is your

Speed Over Ground (SOG) as calculated by the GPS. The distance value displayed as the Range (RNG) is calculated from your present position to the waypoint. The Time-To-

Go (TTG) is the calculated time it will take you to reach the waypoint, based on your Waypoint Closure Velocity

(see NAV4 description).

To keep the screen from jumping around when you are stopped, the screen freezes the graphic representation when your speed is under 0.5 Kn in DGPS mode or 2.0

Kn in GPS mode. Once you get underway, your course details will update appropriately.

• Show Active Route - allows you to turn the course line on or off on the display (assuming a symbol is entered for the first charac ter of the waypoint name).

Simrad MX500 | 33

• Show Off Track Limit - allows you to turn the crosstrack error limit lines on or off on the display.

The Skip Waypoint softkey allows you to skip the waypoint you are presently going to, and advance to the next waypoint. For example, if you were under way and nearing waypoint 5 and you decide you want to go on to waypoint 6 now, press the EDIT key, highlight the Skip

Waypoint softkey, and press the ENT key. If you make a mistake and you want to go back (unskip) to waypoint 5, you can do this by the following:

1 Go into the RTE1 screen.

2

3

Press EDIT in the RTE1 screen.

Highlight the Route Control softkey and press ENT.

4 Highlight the up arrow softkey (fourth from the left) and press ENT once.

Press the EDIT key again. 5

Refer to the Route section of this manual for more details about skipping and unskipping waypoints.

NAV2 - Basic Steering Information

Navigate screen 2 provides the bearing (BRG) and range

(RNG) to the waypoint you are approaching in large easily viewed characters. Below these, you will see your actual Course Over Ground (COG) and Speed Over Ground

(SOG). The bottom portion of the screen provides crosstrack error information. Again, if you don’t see the information described here on your screen, you will need to create a route in RTE1 first (refer to the Route section of the manual).

34 | Simrad MX500

In the bottom half of the window, the vertical line in the center represents your course line. The checkered area on the left and right side of this area represents the out of bounds or beyond the cross-track error limit area.

Whenever the boat is left or right of the course line, the corresponding checkered area changes to solid black, indicating the side of the course line that you are on. The number next to the course line is your calculated crosstrack error. The numbers in the lower left and right hand corners indicate the cross-track limit you set in the CFG1 menu under Navigation. You will notice that the crosstrack error limit lines are slanted, just as they were in the Panorama screen. So if the boat is off to the right of the course, and the bow is pointing straight up, you are actually traveling away from the course line. Keep the bow pointed toward the top of the course line, and you should be able to maintain your course without a lot of drift. The BRG and COG values will confirm this for you, when executed properly.

From time to time, you might drift off course and decide not to return to your original course line. If you drift outside of your cross-track error limit, you can reset your course line from your present position to the waypoint by pressing the EDIT key and selecting Reset XTE from the display. This will save your autopilot from having to work hard to get you back on course. Press the EDIT key again to get back into normal display mode.

In addition, if you decide you want to skip this waypoint, and go on to the next one, Press the EDIT key, and the

Simrad MX500 | 35

Skip Waypoint softkey one time. Press the EDIT key to end this procedure. If you skip one waypoint manually, and the CDU starts skipping more waypoints by itself, you probably need to change your Waypoint Pass Criteria in the CFG1 Navigate menu. Refer to the Route section of this manual for more details about skipping waypoints.

Just as in NAV1, you will see an RL or GC symbol in the upper right corner of the display indicating whether you are navigating under Rhumb Line or Great Circle. This is set in the CFG1 Navigate menu.

NAV 3 - Expanded Navigation Information

Navigate screen 3 has four windows. The upper left window is a smaller version of NAV2. Please read the previous section for a detailed description of this window.

The two windows below this one indicate the current date, time and the ETA to the end of your route for the time zone currently entered. The date and time format is set in the CFG1 Time menu. The ETA and TTG (in the right hand window) are filtered over time, so allow the filtering to settle when you first make a course or speed change. The filter time is controlled in the RTE1 ETA

Setup screen. The Time-To-Go (TTG) value on the bottom of the right hand window expands from HH:MM:SS to HHHH:MM:SS when the time to go is greater than

99:59:59. Also, these values are calculated by using your

Waypoint Closure Velocity (WCV), not your SOG. WCV is described in short detail in the NAV4 section which follows.

You will find the right hand window to be a helpful tool.

In addition to identifying the waypoint you are currently approaching, it identifies the waypoint at the end of the next leg. The really unique feature of this screen is the

36 | Simrad MX500

graphical representation of your actual course line approach angle relative to the next leg of your course. This approach angle is continuously updated in real time and will help you setup for course changes.

Reset XTE and Skip Waypoint, described at the end of

NAV2, is also available in NAV3.

NAV4 - Sensor Input Navigation

The NAV 4 screen applies the wind instruments, speed log, compass, and depth sounder inputs from external sensors to your active route, as appropriate. You can setup the sensors in the CFG1 screen. The Installation

Section of this manual will guide you through the interfacing capabilities of the CDU.

Use the following CFG1 menus to set this screen up:

Compass - Sets the input port number, compass type

(gyro or magnetic), compass deviation table, and the input NMEA 0183 record from which to derive the compass information. The NMEA 0183 record should be specified by the user, because several NMEA 0183 records may contain compass information. This provides you the capability of knowing the compass source exactly. The CDU only accepts NMEA 0183 formatted data for the compass input. Synchro or stepper gyro compasses are not compatible.

Depth - Sets the input port number, units of measure for depths and tide data, sensor offset, alarms, and the input NMEA 0183 record from which to derive the depth information. The NMEA 0183 record should be specified by the user, because several NMEA 0183 records may contain depth information. This provides you the capability of knowing the depth source exactly.

Log - Sets the input port number, sensor type (pulse or

NMEA 0183), alarms, and a correction factor (if needed).

Set & Drift - automatically calculated based on GPS derived values.

Wind - Sets the input port number, units of measure, sensor offset, alarms, and the input NMEA 0183 record from which to derive the wind information. The NMEA

0183 record should be speci fied by the user, because several NMEA 0183 records may contain wind informa-

Simrad MX500 | 37

tion. This provides you the capability of knowing the wind source exactly.

This screen is divided into four windows. The window on the top left provides details relating to the True Wind

Angle (TWA), True Wind Speed (TWS) and True Wind

Direction (TWD), which are taken from the NMEA 0183 record of MWV or VWR. If the wind information is given in relative terms, the CDU calculates true values using available GPS course and speed information to make the necessary adjustments. Refer to the Glossary for definitions on Apparent/True Wind Angle/Speed/Direction. To the right of the wind information is your Velocity Made

Good (VMG) towards the waypoint. The VMG data is filtered to show the average speed from the last waypoint to your present position towards the next waypoint. VMG is calculated from GPS data. The CDU will also use the above data to calculate your speed parallel to wind and can output the VPW NMEA 0183 data sentence to other on-board instruments.

The window below the wind data provides information relating to your course and speed. You will find the Course

Over Ground (COG calculated by the MX421 smart GPS antenna), Heading (HDG, your NMEA 0183 compass input), and Heading To Steer (HTS) data on the left side of the window. HTS data is calculated by considering your

Heading, minus COG and adding BRG to the waypoint. In doing so, the software considers any Set to be included in the HDG value. If there is no Set, your HDG should be equal to COG. Set and Drift is calculated from GPS and your Speed Log (NMEA 0183 VHW record or Pulse input) and Compass (NMEA 0183 HDM, HDT, or VHW) input or an operator manual input.

38 | Simrad MX500

On the right side of the lower left window you will find the Speed Over Ground (SOG, calculated by MX421 smart

GPS antenna), Speed Log (LOG, the NMEA 0183 or pulse speed input), and the Waypoint Closure Velocity (WCV).

WCV reflects the real time velocity from your present position and course towards the next waypoint. The VMG and WCV are calculated from GPS data. Refer to the diagram below to see a graphical representation between

VMG and WCV.

Below this information, you will find your Set and Drift data, which is calculated using GPS and your compass and speed sensor inputs.

Reset XTE and Skip Waypoint, described at the end of

NAV2, is also available in NAV4.

The window on the right displays depth information coming from the depth sounder unit using the NMEA 0183 record of DPT, DBS, DBT, or DBK. These are setup in the

CFG1 Depth screen, refer to the Advanced operation

Simrad MX500 | 39

section and the Installation section of this manual for full details on depth data.

Below the depth data you will find the next route leg vector, the Range to the waypoint and Time To Go data, explained in the NAV3 section.

NAV5 - Compass Display Screen

The NAV 5 screen is used to display the Heading and

Rate of Turn values given by a heading sensor like the

MX575A Satellite Compass. In addition, it also displays the position, COG, SOG, BRG, and RNG. This screen can be accessed by pressing the NAV key repeatedly until you reach the desired NAV screen.

NAV6 - Compass Display Screen

The NAV 6 screen is used to display the Heading and

Rate of Turn values given by the MX575A Satellite

Compass. In addition, it also displays the Set and Drift.

This screen can be accessed by pressing the NAV key repeatedly until you reach the desired NAV screen.

The NAV1 - NAV5 screens are inactive if an MX antenna is not connected or not detected.

40 | Simrad MX500

Route

There are two RTE screens. The NAV functions are highly interactive with the RTE1 screen. The RTE2 screen allows you to create a pool of predetermined routes that you might use often, so you need only create the route one time. Routes are created from waypoints.

All waypoints are stored in the Waypoint Bank, regardless of which function is used to create them. Waypoints are either created in the Waypoint Bank (WPT1), created by the GOTO function, selected from the PLOT screens in conjunction with the GOTO function, or from New

Waypoints that can be defined in the Route Insert menu

(and simultaneously stored in the route and the Waypoint

Bank).

We recognize the diverse needs of professional users.

We have designed the route features to be very flexible to meet a wide range of users’ requirements by allowing up to 2000 waypoints to be stored between all of the routes. You can create up to 99 routes, with any number of waypoints, providing the maximum number of 2000 waypoints between all routes is not exceeded.

The Route (RTE) function serves two purposes:

First, the RTE1 screen provides all of the current, or active waypoint navigation data to the Navigate and Plot screens and is referred to as the Active Route. Therefore, whenever you begin a new trip or voyage, you should erase the previous voyage’s waypoints in this screen, then insert the new waypoints or routes (from RTE2) for the new voyage. If you want to store the waypoints from the previous active route for future use, you can copy these waypoints in the order in which they were entered to the Route Bank in the RTE2 screen. This is described in the RTE2 - The Route Bank section of this manual. If you do not clear the RTE1 screen (refer to Erasing an

Existing Route section of this manual), the RTE1 screen will grow each time you add new waypoints to the route.

The route function can hold a maximum of 2,000 waypoints between the routes stored in RTE1 and RTE2.

Second, the RTE2 screen provides storage space for up to 100 user defined routes. You can pre-define routes,

Simrad MX500 | 41

• or copy new routes from the RTE1 (active route) screen.

Later you can choose individual routes or link two or more routes in the RTE1 screen (refer to Creating a

Multi-Waypoint Active Route section of this manual).

When you are finished using the copied route in RTE1, you can erase the route from the RTE1 screen and the original stored route will remain intact in the RTE2 screen.

The following CFG1 menus directly impact the RTE functions:

• Navigation - sets a variety of important functions and alarms.

-

-

-

Rhumb line or Great Circle navigation.

Range units: nautical miles, nautical miles and meters (when under 1,000 meters), nautical miles and feet (when under 1,000 feet), statute miles, statute miles and meters (when under 1,000 meters), statute miles and feet (when under 1,000 feet), kilometers, or kilometers and meters (when under

1,000 meters).

Waypoint pass criterion and distance: bisector line, perpendicular line, complex (combination of bisector line and perpendicular line), distance to waypoint, or manual.

-

-

Waypoint Approach distance.

Autopilot alarm control.

Position - sets Lat/Lon or UTM and some alarm limits.

Time - sets time offsets and 12 or 24 hour clock mode (for ETA calculation, and waypoint passed time stamp).

RTE1 - The Active Route

The RTE1 screen provides the active route data for the

NAV and PLOT screens. It also maintains a waypoint pass log for you. Another important feature in the RTE1 screen that you need to be aware of is that the up and

down arrow softkeys, displayed when you are in the edit mode under the Route Control softkey, control which waypoints are skipped (down arrow) and which are re-

42 | Simrad MX500

stored (up arrow ) for your current route.

The CDU will recalculate the route when a navigation mode, either Rhumb Line or Great Circle is selected.You can enter waypoints using different datums into the route

The RTE1 screen is where you are likely to do most of your trip preparation. There are several methods you can use to create routes. You are sure to find one or more methods which meet your needs in the following sections.

Creating a Route Using the GOTO Key:

Using the GOTO function key is the fastest way to create a single leg route. Using this method will cause the existing active route to be erased and overwritten with the new position you define.

1

2

From any screen, press the GOTO key.

Press the EDIT key.

3 Using the left or right arrow keys, highlight the softkey desired and press the ENT key:

Waypoint Number - allows you to choose a waypoint stored in the Waypoint Bank. This feature is nice to use if you already know the waypoint number that you want to go to and you don’t want to waste time scrolling through the available waypoints. Enter the number of the waypoint, verify that the coordinates are correct, and press the EDIT key to copy the waypoint to the active route.

Simrad MX500 | 43

Choose In Bank - allows you to scroll through the

Waypoint Bank. Align the cursor with the desired waypoint and press the EDIT key. The waypoint is automatically inserted into the active route and the unit will revert to the NAV screens, displaying bearing and distance to this waypoint.

Lat. Lon. - allows you to define a coordinate and description, which is also stored at the next available waypoint location in the Waypoint Bank. Once the coordinates are defined, press the EDIT key to copy the waypoint to the active route.

Bearing Range - allows you to define a coordinate by specifying the bearing and range from your present position, which is also stored at the next available waypoint location in the Waypoint Bank. After entering the desired bearing and range, press the EDIT key. The newly de-

44 | Simrad MX500

fined waypoint is copied to the active route automatically.

If you make a mistake, you can use the cursor key to position the cursor over the mistake and overwrite the error.

Use the 9 key to insert a space in the description, if needed.

Use the 0 key to select a special character, if needed.

International characters are available by selecting the associated function key. Refer to the EDIT keypad & Display

Description section at the front of the manual.

If you decide you don’t want to continue with this function, highlight the Escape softkey and press the ENT key, then press the EDIT key. Make another function key selection (e.g. NAV) and your original route will have been left intact.

4 Press the RTE function key. You will see two waypoints defined in the center of the screen.

Waypoint 0, the first waypoint, is your Point of

Departure, or the position you were at when you created the route. Waypoint 0 is a unique waypoint, in that the CDU internally constantly changes the position of

Waypoint 0 to your present position. However, the CDU saves and displays the original coordinates entered when you created the route.

Simrad MX500 | 45

Waypoint 0 is displayed in Inverse Video, that is, white characters on a black background (when in the normal

Daylight display mode; see CFG1 Lighting). This indicates that you have already passed this coordinate. The time stamp at the lower portion of the description window indicates when the route was created. If you want to adjust your point of departure position, you can edit Waypoint 0 in the WPT function.

To the right of the coordinate window of Waypoint 0 is a bent arrow. The bend in the arrow is adjacent to the range and bearing between the waypoint you just passed and the waypoint you are approaching. Keep in mind that these are the fixed calculated values between these two coordinates and not the real time changing values that you will see in the navigation screens between your present position and your next waypoint during normal navigation.

Below Waypoint 0 is the waypoint you defined in the

GOTO function. Notice that this information is in standard video, black characters on a white background, and that an ETA time is displayed in the same position as the waypoint passed time in Waypoint 0. This indicates that the waypoint has not yet been passed. Remember that the ETA time is filtered over time, so allow a few minutes for the filter to settle when you first get underway or make course and speed changes.

Erasing an Existing Route

To erase the active route:

1 Select the played.

The active route is now erased and ready for new input.

If you want to work in other areas of the CDU first, you will need to press the EDIT key to exit the edit mode.

Creating a Multi-Waypoint Active Route

Simrad MX500 | 47

The following four sections are examples of how to use each of the four basic functions outlined above. We encourage you to experiment using all of the methods available to find the one that best meets your needs. As long as you are working in the RTE1 screen and sitting at the dock, you are not going to do any damage (e.g. erase waypoints in the Waypoint Bank or routes in the

Route Bank), so have some fun and find out how helpful

this GPS receiver really is.

If you are already comfortable with setting up a basic route, you might want to skip the examples which follow and jump ahead to the Maneuvering Within the Route section later in this section to understand some of the more advanced features of the software.

You can then choose to select another route using the same method or select another method to enter waypoints.

Don’t forget to press the EDIT key to end your editing.

Maneuvering Within the Route

Scrolling

You can use the cursor key to scroll up and down the active route. You will probably want to do this when you update your log book to indicate when you passed a given waypoint, or when you want to know the ETA to a waypoint other than the one you are currently traveling towards. It is also a good idea to set the cursor at the correct waypoint before entering the edit mode to insert and delete waypoints from the route.

Skipping and Unpassing Waypoints

You are likely to run into an occasional circumstance where you accidentally skipped a waypoint (due to your waypoint pass criteria selection in the CFG1 Navigation screen, or a manual skip in the NAV screens), and you want to switch back to a previous waypoint in the active route. You may also decide at some point that you want to skip the current or subsequent waypoints in the route.

The software has a very simple design to accomplish both of these tasks.

The easiest way to accomplish either of these tasks is to scroll through the route with the cursor key until the cursor arrow is at the bottom of the last waypoint you want designated as passed (that is, white characters on a black background), whether this waypoint was passed several waypoints ago or is yet to be passed.

Then press the EDIT key.

Simrad MX500 | 53

Use the up ( ↑) softkey to unpass or the down (↓) softkey to pass waypoints in the route until the waypoint marked by the cursor is displayed with white characters on a black background (Daylight display, see CFG1 Lighting).

Press the EDIT key to end editing.

If for some reason you can’t select the waypoint you want (the screen keeps passing waypoints you unpassed), you are probably too close to one of the waypoints. You will need to either change your Waypoint Pass

Criteria, change your Waypoint Pass Distance (see CFG1

Navigation), or remove the waypoint from the route.

Inserting Waypoints or Routes into an Existing

Route

Then press the EDIT key.

Use one or more of the insert methods described in the Creating a Multi-Waypoint Active Route section above.

This example shows Waypoint 7 inserted into the route using the Insert by Number method:

5 Press the EDIT key to end editing.

There is one special way to add a waypoint to the active route using the Plotter display. This method adds the waypoint between your present position and the next waypoint in your active route.

1 Select either PLOT1 or PLOT2 display.

2 Use the UP arrow (zoom-out) or DOWN arrow

(zoom-in) key to display the waypoint you want to insert. Press the EDIT key. All waypoints in the waypoint bank will be displayed if they are within the zoom level of the display.

Note that the waypoint must have a symbol as the first character of the waypoint name in order for it to be displayed on the PLOT screen when the edit mode is not active.

Simrad MX500 | 55

3 Use the cursor key to move the magnifying glass icon over the waypoint or marker that you want to go to.

Verify that the waypoint number and coordinates are correct in the left hand window.

4 Press the GOTO function key.

5 Press the EDIT key to exit the edit mode.

Note that RTE1 and PLOT1 are updated with your new waypoint.

Reversing the Active Route

Once you get to your final destination, you might want to follow the same route home. To quickly accomplish this, simply use the Reverse Direct softkey from the main

RTE1 menu.

1 Select the played.

RTE key until the RTE1 screen is dis-

Press the EDIT key. It’s that simple!

Notice that you still keep the same orientation on the screen, in other words, you always read from the top of the screen to the bottom of the screen. The waypoints are rewritten in reverse order for you.

ETA Setup

If you choose to use this function, it is probably better to operate the unit in UTC time mode if you are going to cross one or more time zones. Note that the time entered uses the offset to UTC applied in the CFG1 Time display.

The software calculates Estimated Time of Arrival based on how you configure the unit. ETA settings are controlled from the RTE1 screen. To change the ETA settings:

Select the RTE key until the RTE1 screen is displayed.

Press the EDIT key.

Highlight the ETA/SOG Calc. softkey and press

ENT.

Simrad MX500 | 57

4 Highlight the Change softkey and press ENT to select which value you want the CDU to calculate, either ETA based on speed, or speed (SOG) based on desired time and date of arrival.

SOG Based on Arrival Date & Time:

1 Enter the arrival time and date. Be sure to enter the date as day, month, year, as indicated on the screen.

Highlight the Done softkey and press ENT.

2

In this mode, the actual SOG is compared to the required SOG to meet the specified arrival date and time.

The result is given in a percentage (%) value next to the displayed SOG in the NAV screens. If the percentage is below 100, you will arrive late. If the percentage is above

100, you will arrive early.

58 | Simrad MX500

ETA Based on Speed:

Select a Speed Basis of either GPS SOG, which uses a long filter time (in seconds) that you define, or Constant, which uses a speed you intend to maintain (you define the speed).

Highlight the Done softkey and press ENT.

RTE2 - The Route Bank

The Route Bank is a convenient place for you to preprogram segments of a long voyage, or to program routes that you follow over and over again. Creating routes for the Route Bank uses the same methods as the Active Route with a few exceptions: you can’t use the GOTO key, and you can’t use the Plotter screen.

You can use other routes as a subset to create a new route. Remember, you can always tie routes together in the Active Route by inserting one after another. You will find a Route Name softkey when you first enter the edit mode. The Route Name selection allows you to identify each route by name, number and symbol when you are viewing the Route Bank from the main menu. To create a route:

1 Select the RTE key until the RTE2 screen is displayed.

2

3

4

Move the cursor to the route number you want to create or edit.

Press the EDIT key.

Use the entry methods described in the Creating a

Multi-Waypoint Active Route section, following the exceptions noted above.

Simrad MX500 | 59

If you have a route in RTE1 that is not stored in RTE2, you can copy it into the Route Bank by selecting Insert then

Insert Route, either in the forward or reverse direction.

5 When you are finished selecting waypoints, highlight the Route Name softkey and press ENT. You can enter any name, number or symbol you want this route to be identified by.

6 Highlight the Done softkey and press ENT when you are finished editing the name.

It is a good idea at this point to select Lock Route so that way you won’t accidentally erase the route.

7 Finally press the EDIT key to exit the edit mode.

The RTE1 screen is inactive if an MX antenna is not connected or not detected.

60 | Simrad MX500

Waypoint

The Waypoint Bank (WPT) is a single list of up to 2,000 waypoints that you store for use in the routes you create.

It also stores special coordinates and time, through the use of the Mark or Event function key or external input, or the MOB function key or external input. You can also enter waypoints from other NMEA 0183 devices (see

CFG1 WPT & RTE In), such as plotters. You can also output waypoints and routes from the CDU to other NMEA

0183 devices (see CFG1 NMEA Out Rnn, RTE, and WPL).

You can input very accurate coordinates, down to 18 cm in Lat/Lon or 0.1 m in UTM. You can select from more than 110 Datums to store your waypoints in. The CFG1

Position screen controls which coordinate reference system is used by the CDU.

While entering waypoints in the list is rather straight forward, the software does provide some helpful features that should be mentioned before giving any examples.

There are six methods to view or sort waypoints:

• Sort By Number - displays the waypoints in waypoint numerical order, starting with waypoint 0.

You can manually alter Waypoint 0 to a different Point of

Departure if you don’t want to start your route from your present position.

Sort By Name - displays the waypoints by name in alphabetical order.

Sort By Type - displays the waypoints by symbols, numbers, then names.

Sort By Distance - displays the waypoints which are closest to your present location first.

Sort By Age - displays the waypoints entered most recently, first.

Simrad MX500 | 61

• Search For WPT - allows you to type a symbol or name and the screen displays all waypoints having the exact match of the name you type. If you are unsure of the complete name, type a few of the characters you know are in the name, and the software will display all waypoints having the corresponding characters.

For example, if you are looking for the LA HARBOR

ENTRANCE and you enter HAR, the screen will display all waypoints with these three characters in this exact order.

Creating and Editing Waypoints

When editing a waypoint, you are always prompted to select the appropriate datum. You might occasionally see a prompt warning you that the waypoint is used either in a stored route or the active route. You ultimately have the final decision whether to continue editing the waypoint, or exiting this waypoint by pressing the EDIT key again to

exit the edit mode.

Creating and editing waypoints is easy.

You can press the EDIT key when you finish editing a waypoint. This is treated the same as highlighting the Done softkey and press ENT.

Highlighting Done then press ENT allows you to continue editing and entering other waypoints.

Waypoint Lock/Unlock

Locking a waypoint forces the user to consciously unlock the waypoint before it can be modified and prevents the waypoint from being overwritten when waypoints are be-

66 | Simrad MX500

ing input over the data port. Note that when a waypoint received on the data port has the same waypoint number as a locked waypoint already stored in the CDU, the waypoint data received on the data port is disregarded and lost. Waypoints are locked by one of three methods: 1) selecting Lock this WPT when in the waypoint bank edit mode for a particular waypoint; 2) selecting Lock this

WPT when in the waypoint bank edit mode; or 3) incorporating a waypoint into a route stored in RTE2 and then locking the route.

Waypoints that are locked from the waypoint bank are indicated by a closed padlock in the display. Waypoints that are party to a locked route will display a message indicating that waypoint can not be modified.

Removing Waypoints

Unlocked waypoints can be overwritten by waypoints received on the NMEA port or downloaded from the USB stick. Waypoints that are contained within a stored route can not be removed until they are removed from the stored route in the RTE2 screen. If you try to remove a waypoint stored in a route, a warning will be displayed indicating the first route a waypoint is stored in.

If the waypoint you want remove is locked, refer to the

Waypoint Lock/Unlock section for a step by step procedure, and then return to this section.

Simrad MX500 | 71

If the destination waypoint number is already being used, you will be prompted to either overwrite the first waypoint (Yes) and each subsequent waypoint that is to be overwritten, confirming each waypoint one at a time, overwrite all the waypoints (Yes To All), not overwrite any waypoints (No); or Escape back to base softkey menu.

Downloading Waypoints & Routes to Other

Devices

Refer to the Installation section of this manual for hardware interfacing guidelines.

The CDU can download all of your stored waypoints and routes, and your active route to other NMEA 0183 devices which accept the RTE, Rnn, and WPL data sentences.

These sentences are controlled in the CFG1 NMEA Out screens for the identifier given below. The CDU outputs these sentences in the following format:

72 | Simrad MX500

Rnn - Routes:

Waypoint identifiers, listed in order with starting waypoint first, for route number “nn”. The active route in the

CDU is always route zero, but in the Rnn sentence the route number can be transmitted as either route 00 or

01.

Rnn is NMEA version 1.5. Use of GPRTE is recommended to comply with NMEA version 2.1.

field#: 1 2 3 4 1 1 1

4 5 6

$GPRnn,cccc,cccc,cccc,.....,cccc,cccc*hh<CR><LF> explanation / actual use:

1: nn = active route number, 00 or 01

can be set to 00 or 01 (default 00).

2 - 15: 14 field sequence of route waypoint IDs.

16: Checksum can be set on or off (default on).

RTE - Active Route:

Waypoint identifiers, listed in order with starting waypoint first, for the identified route. Two modes of transmission are provided: “c” indicates that the complete list of waypoints in the route are being transmitted; “w” indicates a working route (active) where the first listed waypoint is always the last waypoint that has been reached

(FROM), while the second listed waypoint is always the waypoint that you are currently heading toward (TO). The remaining list of waypoints represents the remainder of the route.

RTE can be sent as version 2.1 and 2.0.

field#: 2 3 4 5 6 1 1 1

5 6 7

$GPRTE,x,x,a,cccc,cccc,.....,cccc,cccc*hh<CR><LF> explanation / actual use:

2: Total number of messages being transmitted (a single route may require the transmission of multiple messages). A maximum of 11 waypoints are transmitted in each messages.

Simrad MX500 | 73

3: Message number.

4: Message mode: c = complete route, all waypoints, w

= working , 1st listed waypoint is ‘FROM’, 2nd is ‘TO’ and remaining are the rest. c/w can be set to c or w (default w).

5: Route identifier, always 00 (Active Route only).

6 - 16: Waypoint identifiers, (less than 11 waypoints may be in the message).

The number of remaining waypoints can be set to 1, 2 or

“all” (default all) shortening the drawn track on the plotter.

17: Checksum can be set on or off (default on).

WPL - Waypoint Location - NMEA 0183

Standard:

Latitude and Longitude of specified waypoint. The content of this sentence will normally be the position of the next waypoint in the route.

The CFG1 NMEA out WPL has a special “Send All” option.

Selecting this feature will send all the waypoints in the

Waypoint Bank once, independent of the WPL sentence setup as ON or OFF. This format conforms to the NMEA

0183 standard.

WPL can be sent as version 1.5, 2.0 or 2.1.

Uploading Waypoints from Other Devices

The CDU will accept waypoints from any device which follows the WPL formats identified earlier in the Waypoint section. The first two characters following the $ can be any NMEA defined talker ID. You do not have to calculate and include the checksum; however, you must end each data record with a carriage return and line feed. If you do include the checksum at the end of the data record, the CDU will verify the checksum. If the checksum is invalid, the waypoint will be rejected.

Waypoints received on the data port will be stored to the waypoint location specified in the WPL record. If the waypoint location specified in the WPL record is already occupied, the CDU will overwrite the existing waypoint

(if it is unlocked). If the existing waypoint is locked, the

WPL record received on the input port will be ignored and dropped.

The CDU will only recognize waypoints from one input port at any given time. This port is defined in CFG1 WPT

& RTE In.

Uploading Waypoints from a Personal

Computer

You can use any terminal or communications program to download or upload waypoints and routes to or from the

CDU and a PC.

Set the PC to:

4800 baud

8 bits

1 stop bit no parity no flow control

78 | Simrad MX500

When sending data to the CDU, it must be sent in block form, followed by (with an appended) CR (carriage return) and LF (line feed). Normal communications programs, like Windows XP Hyper Terminal are sufficient to get the job done.

Using Windows XP Hyper Terminal, do the following (from the Program Manager):

1 Using an RS-422 to RS-232 convertor, connect the

CDU’s port 1 or 2 to the PC’s communications port

(Refer to the page 195 - MX500 PC Interface sec-

Uploading Waypoints from a USB Memory

Stick

Waypoints and routes can also be downloaded or uploaded using a USB device (i.e. USB flash drive). Please refer to the CFG1/USB feature of this manual for details.

Mark or MOB

This is a dual function key that either stores your present position, date and time at the next available waypoint location in the Waypoint Bank or when pressed continuously for 3 seconds, calculates a MOB range and bearing to a saved spot. A window pops up on the screen to confirm your key depression, and to tell you where the Mark position is being stored. You can go into the WPT menu and edit the coordinates or description later. This key function is disabled for 2 seconds after each depression.

The cross-hair symbol to the left of the date in the

Waypoint Bank indicates that the Mark or Event key created this waypoint. Note that you can also select the cross-hair symbol from the various symbols for other waypoints when editing waypoints.

The CDU is also capable of performing this function from a remote contact closure input via the 8-pin AUX Cable

“MOB/Event” wire. Refer to the Installation Section of this manual for interface instructions. Contact closure on the two input pins for 1 second causes a Mark position to be generated. Contact closure on the two input pins for 3

80 | Simrad MX500

seconds causes a Man Over Board condition to be generated.

The marker function stores the position of the antenna location. Keep this in mind if you are trying to pinpoint items such as buoys, crab pots, etc. For some special applications such as these, you may need to locate the antenna at the point on the boat or ship where you need to make this exact measurement.

GOTO

Using the GOTO function key is the fastest way to create a single leg route. This method will cause the existing active route to be erased and overwritten with the new position you define.

1

2

From any screen press the GOTO key.

Press the EDIT key.

3 Select the waypoint determination method you want:

Waypoint Number - allows you to choose a waypoint stored in the Waypoint Bank, where you enter the waypoint number.

Choose in Bank - as used in the Route function (refer to Route - Choose In Bank section of the manual), allows you to view waypoints in the

Waypoint Bank as a list.

Lat. Lon., UTM- allows you to define a coordinate and description, which is also stored at the next available waypoint location in the Waypoint Bank.

Bearing Range - allows you to define a coordinate by specifying the bearing and range from your

Simrad MX500 | 81

4 present position, which is also stored at the next available waypoint location in the Waypoint Bank.

If you make a mistake, you can use the cursor key to position the cursor over the mistake and overwrite the error.

Use the DGPS key or cursor key to insert a space in the description, if needed.

Use the CFG key to select a special character, if needed.

To activate the GOTO waypoint, press the EDIT key. A warning is briefly displayed indicating that the active route will be replaced with the GOTO route.

If you decide you don’t want to continue with this function, highlight the Escape softkey and press

ENT, then select another function key (e.g. NAV).

Your original route will be left intact.

Press the RTE function key. You will see two waypoints defined in the center of the screen.

Waypoint 0, the first waypoint, is your Point of Departure, or the position you were at when you created the route.

The CDU saves and displays the original coordinates, date and time when you created the route in Waypoint 0.

82 | Simrad MX500

Waypoint 0 is displayed in Inverse Video, that is, white characters on a black background (when in the normal

Daylight display mode; see CFG Lighting). This indicates that you have already passed this coordinate. The time stamp at the lower portion of the description window, indicates when the route was created.

To the right of the coordinate window of Waypoint 0 is a bent arrow. The bend in the arrow is adjacent to the range and bearing between the waypoint you just passed and the waypoint you are approaching.

Keep in mind that these are the fixed calculated values between these two coordinates and not the real time changing values that you will see in the navigate screens between your present position and your next waypoint during normal navigation.

Below Waypoint 0 is the waypoint you defined in the

GOTO function. Notice that this information is in standard video, black characters on a white background, and that an ETA time is displayed in the same position as the waypoint passed time in Waypoint 0. This indicates that the waypoint has not been passed yet. Remember that the ETA time is filtered over time, so allow a few minutes for the filter to settle when you first get underway or make course and speed changes.

Plot

The RTE1 and WPT functions are highly interactive with the PLOT screen. The PLOT1 screen displays graphic information around the boat at your present position. The boat always remains in the center of the screen. The Plot screen provides basic navigation information, zoom-in/ out capability and scaling factors for the display from around 10 to 20 meters, depending on your latitude, out to 128 nautical miles.

The Plot screen will not show your route and cross-track error lines when in Great Circle Navigation mode.

Simrad MX500 | 83

The following CFG menus directly impact the PLOT functions:

• Navigation - sets a variety of important functions and alarms.

-

Rhumb Line or Great Circle navigation

Range units: nautical miles, nautical miles and meters (when under 1,000 meters), nautical miles and feet (when under 1,000 feet), statute miles, statute miles and meters (when under 1,000 meters), statute miles and feet (when under 1,000 feet), kilometers, or kilometers and meters (when under

1,000 meters)

-

-

Waypoint Pass Criterion and distance

Waypoint Approach distance

-

-

Autopilot alarm control

Cross-track error limits

• COG / SOG Filter Settings.

Take a quick look at both screens. They both have a graphical area to the right, and a text data area to the left.

In the PLOT screens the UP arrow key is the Zoom-out key; the DOWN arrow key is the Zoom-In key. Each time you depress one of these arrow keys, you scale by onehalf or by double the graphical area. If you look to the top of the screen, just right of the page number (PLOT

1 ), you will see a number in a white square. This is the scale of the graphic window based on the units selected in CFG1 Navigation.

Now look along the left and right edge of the graphic window, you will see some vertical black and white dash marks (these are harder to see at small scales like 1 and

84 | Simrad MX500

2 or at large values such as 64 or 128). Each solid dash mark represents 1 nautical mile. A broken dash mark indicates 1/100th of a nautical mile when you are zoomed in at low scale. You will find your bearing and range to the next waypoint just below the page number.

The CFG1 Navigation menu allows you to display fractions of the major unit (nautical miles, statute miles, or kilometers) ranges less than 1000 in alternate units of feet or meters.

PLOT 1 - Relative to Boat

The information in PLOT1 is always relative to your present position. The boat always remains in the center of the screen and the bearing and range are always from your present position to the next waypoint identified in RTE1.

Customizing the Display

There are a number of display options available, press the EDIT key to modify the screen to your needs.

Highlight the Display Options softkey and press the ENT key.

The following choices are available:

Simrad MX500 | 85

Show Boat - Yes is the default condition, which places the boat icon in the middle of the screen. No places the boat in a Compass Rose in the upper right corner of the screen (see the diagram below), where your direction is indicated by the boat in the Compass Rose.

The boat’s position is then indicated by an X in the center of the screen.

Show All Waypoints - Yes is the default condition, which displays all waypoints, where the first character of the description is a symbol, in its proper location relative to the boat’s position. No causes none of the waypoints to be displayed.

Show Active Route - Yes is the default condition, which causes the active route (course lines) and its waypoint symbols to be displayed. No causes the course lines not to be displayed. Note that these lines can only be displayed in Rhumb Line navigation mode (see CFG1

Navigation).

Show Recorded Track - Yes is the default condition, which causes the course you have already traveled to be displayed. No causes the traveled course not to be displayed.

Show Off Track Limit - Yes is the default condition, which causes the active route cross-track error lines to be displayed. These are only displayed for the leg of the course you are presently on. If you reset your cross-track error, these lines are redrawn to reflect the course change (see NAV2). No causes the crosstrack error lines not to be displayed. Note that these lines can only be displayed in Rhumb Line navigation mode (see CFG1 Navigation).

86 | Simrad MX500

• Show Lat/Lon Grid - No is the default condition, which causes the coordinate grid not to be displayed. Yes causes the Lat/Lon grid to be displayed (regardless of positioning reference system selection in CFG1

Position). Note that the grid is only displayed at the 4

Nm scale or lower.

Selecting Erase Track then pressing the ENT key allows you to clear your recorded track. You can keep a portion, say the last mile or two, of your recorded track if you like, by specifying the range after you highlight the Erase

Track softkey and press ENT. Highlight Erase Now and press ENT to confirm your action. Highlight Escape and press ENT to return the previous screen without erasing or EDIT to abort this process.

Simrad MX500 | 87

Selecting Record Track then pressing ENT allows you to define how your course is saved. Choosing not to save your track may free the processor up to run other functions a little bit faster; however, you are not likely to notice any difference in performance unless all data ports are near their full throughput capacity. You also have three different levels of track saving capability: Normal,

Fine, and Detailed. The software saves each calculated position coordinate to draw the lines for the plot screen.

There are a finite number of plot points which can be saved in memory, before the CDU begins overwriting the first set of plot points. If you are traveling a long distance at a high rate of speed (say over 10 knots) you probably will want to use the Normal selection, which only stores a plot point when your direction changes. If you are doing some tight maneuvering or station keeping tasks, you will probably want to use the Detailed selection, which stores a position every 0.5 meters. The Fine selection stores a plot point every 7 meters.

The PLOT screen is inactive if an MX antenna is not connected or not detected.

88 | Simrad MX500

Man Over Board

The Man Over Board function key shares the same key with the “Mark or Event” function key. When depressed for 3 seconds, it activates a number of automatic functions described below.

Most obviously, it brings up an MOB1 (Plot) screen. This is an automatic scaling screen. The screen centers on half the distance between your present position and the

MOB position. In addition, the MOB position is displayed in the upper left corner, so that you can quickly read the coordinates to others who may be available to render assistance. This plot screen also provides the vital bearing and distance back to the MOB position, as well as your present course over ground.

The MOB position, date and time are stored in the next vacant waypoint memory of the Waypoint Bank for future reference (e.g. log book entries). An MOB symbol is used to denote an MOB waypoint.

The range and bearing in the PLOT, NAV, and MOB screens all reflect your bearing and range back to the MOB position, not the active route, until the MOB is canceled.

NMEA 0183 sentences (i.e. BWC and BWR) and the printer output are changed to reflect the current crisis situa-

Simrad MX500 | 89

tion by also indicating the bearing and range back to the

MOB position (until the MOB is canceled). This way, other interfaced equipment can also help guide you back to the

MOB position. When the MOB condition is canceled, the

NMEA sentences will automatically revert to the active route information. Don’t forget to cancel the MOB so your

interfaced equipment will read the correct data.

The MOB function key and remote MOB input are disabled from subsequent activation until Cancel MOB is selected.

Other functions such as Position and Navigate can still be accessed; however, the screen will revert to the MOB Plot screen after 30 seconds.

To cancel an MOB condition, make sure you are in the

MOB Plot screen. Press the EDIT key, then highlight the

Cancel MOB softkey and press ENT. Press EDIT again to exit the edit mode.

Remote MOB

The MX500 is capable of performing the MOB function from a remote contact closure input via the AUX (8-pin) cable. If the contact closure is made for 3 seconds, the input is registered as a MOB Position. Refer to the installation section of this manual for wiring interface instructions.

90 | Simrad MX500

Auxiliary

There are eight Auxiliary screens described in this section:

AUX1 - Alarm Log

AUX2 - Speed Graph

AUX4 - Sun Almanac

AUX5 - Moon Phases

AUX6 - Batteries

AUX7 - Unit Information

AUX10 - Current Tide Display

AUX11 - Tide Table Port List

AUX1 - Alarm Log

All alarms are registered in this screen, whether or not they have been corrected, until the log is erased or the log is full. When the log is full, the oldest alarms are overwritten. Alarms with an asterisk (*) next to the alarm number have not been corrected and can not be reset until they are corrected.

Reset Log clears the alarm log entries, except for any alarm conditions which have not been corrected and any alarms which have occurred since the uncorrected alarm.

Simrad MX500 | 91

AUX2 - Speed Graph

The graph scales automatically to the speed you are at.

You can zoom out to the last 56 minutes or in to the last

3.5 minutes. It is a handy tool if you are trying to maintain a certain speed.

AUX4 - Sun Almanac

This almanac provides the sunrise and sunset times for a given day and location. You can enter another date or location of interest by pressing the EDIT key, and editing the appropriate date and/or place.

92 | Simrad MX500

AUX5 - Moon Phases

There are no edit functions available here. Moon phases are given in approximately one week increments and include all dates for new, half, and full moon. You change the year displayed by pressing the up or down cursor keys.

AUX6 - Batteries

This is where you reset the Lithium battery age. Press the EDIT key and highlight the Reset Age softkey then press ENT after you replace the Lithium battery. Please note that the age reset requires that the unit is tracking satellites.

Battery replacement should be done by an authorized servicing dealer.

Simrad MX500 | 93

AUX7 -Unit Information

This screen indicates the specific CDU model, software version number, the hardware configuration, and the printed circuit board (PCB) serial number of your CDU.

If you are having problems with your CDU, refer to this screen for information to provide to customer service personnel.

A special softkey sequence displays sub-version levels, the actual software build date and time, and allows access to a selftest sequence. This information is useful to the technician and our Field Engineers during troubleshooting. To activate the screen press the EDIT key, then press the ‘1’ or ‘NAV’ key three (3) times. Additional information in the Software window will be displayed.

MX500 AUX7 Screens

This also activates several engineering screens (the same as turning Engineering Display to Yes in CFG1 Operation).

Refer to Appendix C - Engineering Mode for more details.

94 | Simrad MX500

Tide

There are two TIDE screens, which are located under the AUX option. The AUX 10 screen displays graphic and digital information about the tide conditions at your present position. This is based on tide table constants that you must enter in the AUX 11 screen, then access through the AUX 10 screen. You can store up to 100 tide tables in AUX 11.

The following CFG1 menus directly impact the TIDE functions:

• Depth - sets the measurement units in meters, feet, or fathoms.

The Tide function is not active in the MX500 Basic model without the MX antenna.

AUX 10 - Current Tide Display

This screen provides the current tide conditions for the tide constants indicated in the upper left hand corner.

The number in the upper left corner of the window is the identification number of this table in the British Admiralty

Tide Table and in the AUX 11 screen. The name to the right of this number is the port name you entered in the

AUX 11 screen.

A graphical representation of the tide is given in the middle of the screen. The tide peak references are given to the right of the High/Low time on the right of the screen.

High/Low tide times are given to the right of the graph.

The marker time (indicated by the clock icon or + sign in the graphic area) and tide condition are given below the

High/Low tide information.

The tide marker automatically updates to the current

Simrad MX500 | 95

time. When the tide marker is in the automatic mode, the cross-hair indicator is enclosed with a circle (like a clock).

You can move the marker forward or backward in time using the softkeys at the bottom of the screen. Return the marker to the present time by simply highlighting the

Marker to Now softkey then pressing the ENT key. When you move the tide marker off of the present time, the marker changes to a + sign. The marker will remain at the manually positioned mark until you either select one of the manual marker control softkeys, or until you highlight the Marker to Now softkey and press ENT - which returns the marker to automatic mode (indicated by the clock marker).

The tide measurement units can be displayed in meters, feet, or fathoms. Tide units are controlled along with depth units in the CFG1 Depth screen.

To select another port’s tide table, press the EDIT function key, and use the Change softkey to scroll down the list or the Go Back softkey to scroll up the list. You can also use the left and right cursor keys to scroll through the tide tables available in AUX 11.

While in the edit mode, you can also move the cursor down to the date and manually change it to any date you are interested in.

Once you have found the table you need, press the EDIT key again to load the table.

AUX 11 - Tide Table Port List

AUX 11 is where you store the constants for the port tide tables you are interested in. You can store up to 100 tide tables. The constants you need can be derived from Part

III of:

The display provides the required tide table document name and section (Admiralty Tide Tables, Part III) under the Help softkey when in the edit mode as an added aid to help you identify the proper reference material.

The Admiralty Tide Tables port lists are also available, free of charge. Contact your dealer or us at the address, fax, e-mail, or phone number provided at the back of this manual if you have not received a copy of these tide table lists.

Simrad MX500 | 97

Adding a Port

To add a port to the list, first locate it in Part III of the tide table book, then align the cursor with Add port to

the Port List and press EDIT. The Zone in the upper left corner refers to the time zone offset to UTC. Use the name given in the tide table for the name given in the

Place portion of the screen. To help you locate this port in the printed volume later, use the table number given in the first column of the manual as the tide number in the

CDU.

Then simply follow along the table in the manual and enter the appropriate offsets. The software is setup just like the manual. You may encounter a table that requires seasonal offsets. Where these might apply, the

CDU provides you the opportunity to input a Fixed value or the seasonal Table values. Highlight the first softkey and press ENT to toggle between these two selections.

Highlight the second softkey, Edit Table, and press ENT to make the necessary corrections. Highlight the Done softkey and press ENT when you finish the seasonal table, otherwise press the EDIT key when the necessary data is entered.

You can scroll through the entered tables with the up and down cursor keys when you are not in the edit mode. You also have the option to modify or delete a port from the list.

Tide table information is mapped to an area of RAM which is saved during future software upgrades.

98 | Simrad MX500

Position

There are three POS screens in the CDU. The POS functions are highly interactive with a number of CFG1 menu selections.

GPS - sets an offset for calculating the GPS antenna position if you can’t physically locate the antenna exactly where you want it (i.e. over the centerline of the boat); sets the minimum elevation angle to look for satellites; and in 6 channel models, it also controls the satellite selection process.

Navigation - sets a variety of important functions and alarms (used in other function screens), but only the

Range units:

-

-

-

-

-

-

-

nautical miles (Nm) nautical miles and meters (Nm/mtrs) nautical miles and feet (Nm/ft) statute miles (Sm) statute miles and meters (Sm/mtrs) statute miles and feet (Sm/ft) kilometers (Km), or kilometers and meters (Km/mtrs), affect the POS screens.

Position - sets Lat/Lon or UTM, Grid (optional) and some alarm limits.

Time - sets appropriate offsets, and 12 or 24 hour clock mode.

Simrad MX500 | 99

POS1 - Position Display (Large Digits)

This single window display provides the largest presentation of the coordinate information from the CDU. In addition to the coordinates and datum in use, this screen displays the current course and speed over ground.

There are no edit functions available in this screen unless it is in Demonstration mode. Refer to Appendix E -

Demonstration Mode for a full description of this feature.

Latitude & Longitude

UTM

When using the UTM reference system in the polar regions of the Earth, the CDU displays position using the

UPS coordinate system instead of invalid UTM coordinates.

User GRID

User defined grids is an optional feature of the MX500.

When enabled you can set the receiver to provide Easting and Northing position data based on a local grid. The grid function is set up in the CFG1 Position screen. A license is required to activate this special feature.

100 | Simrad MX500

POS2 - Position, Altitude, Magnetic Variation,

& Time

This screen is divided into three windows. The upper left window provides your position coordinates, the antenna altitude (above Mean Sea Level - MSL), altitude mode (2D or 3D), the magnetic variation (Variation) for your present position, and the present datum in use for calculating your position.

The lower left window displays your course and speed over ground. If the degree symbol has a small ‘c’ under it, this indicates that the magnetic variation and compass deviation table are being calculated and displayed. Refer to the CFG1 Compass section for more details on how to set this up.

The right hand window indicates today’s date and time.

This setup is in the CFG1 Time menu. It can be set for

UTC time, local 12 hour time, or local 24 hour time.

There is an added summer/winter feature to help you remember which direction to set the clock for day light savings in the summer.

There are no editing capabilities in this screen.

POS3 - Position & Log

This screen is divided into three windows. The upper left window is the same as POS2 and provides: your position coordinates, the antenna altitude (above Mean Sea Level

- MSL), altitude mode (2D or 3D), the magnetic variation

(Variation) for your present position, and the present datum in use for calculating your position.

Simrad MX500 | 101

The lower left window is also the same as POS2 and displays your course and speed over ground. If the degree symbol has a small c under it, this indicates that the magnetic variation and compass deviation table are being calculated and displayed. Refer to the CFG Compass section for more details on how to set this up.

The right hand window indicates your accumulated mileage since the CDU was first turned on.

You will also find two Trip Reset softkeys if you press the

EDIT key. Two trip logs are provided so that you can log the mileage for: a the current leg or day of your trip; and b the entire trip.

You will also find a flashing cursor on the second line in the Trip Log. This is provided so that you can label what type of mileage you are logging. Edit this field the same way you would any of the description fields for the waypoints.

102 | Simrad MX500

GPS

Several GPS and DGPS screens are available under the

GPS function key. The GPS/DGPS functions are highly interactive with these CFG1 menu selections:

GPS - sets the lowest elevation at which a satellite will be tracked.

DGPS - sets the internal beacon receiver to Auto,

DGPS only, or Off.

GPS1 - GPS Status Screen

There are two windows in this display. The left window has twelve graphic Power Bars representing the twelve

GPS receiver channels of the MX421 antenna. The PRN

(PseudoRandom Number) under each power bar represents the satellite ID number assigned or being tracked on that channel. The power bars indicate the valid receiver power range from 30 to 50. Any portion of the power bar which is filled in, indicates that a satellite is being tracked on that channel. If a power bar is empty, but a PRN number is labeled under the power bar, then the identified satellite is not currently being tracked.

The graphic on the right hand side of the screen indicates where the satellites are relative to your present position. The outer ring represents 0° elevation. The inner ring represents 45° elevation. The + sign represents 90° elevation and your present position. Under normal conditions, the best satellites to track are usually between 15 and 75 degrees in elevation.

GPS 3 through GPS 4 screens are skipped under normal operation.

Simrad MX500 | 103

GPS2 - GPS Health Screen

There are two windows in this display, the top window is a table indicating which satellites are reported

Healthy or Unhealthy by the satellite almanac. The PRN

(PseudoRandom Number) ID table is divided into columns and rows. The rows represent the 10’s digit of the

ID number and the columns represent the 1’s digit of the ID number. The satellite system consists of up to 32

ID numbers. The ID numbers are called PseudoRandom

Numbers.

To find a particular satellite ID, for example PRN 24, go down the left hand column and locate the 10’s digit (2- in this case). Then go across the row until you intersect with the appropriate 1’s digit (in this case 4).

The bottom window provides some basic satellite tracking performance information. The HDOP and VDOP values indicate the current Horizontal or Vertical Dilution Of

Precision.

The Used Sats value indicates the number of satellites used in the navigation filter to calculate your position

The Elevation Mask sets the lowest elevation at which a satellite will be tracked. Satellites with an elevation below this number will not be tracked, even if they are otherwise available to track.

Unhealthy Satellites

Satellites are expected to fail at some point in time and they may cause the position calculation to become erroneous. With RAIM enabled units, you will be able to determine which satellite PRN number is causing the position error. The operator can then decide to manually force the offending satellite to “unhealthy”. A satellite that is marked as unhealthy will not be used for position calculation.

Press the EDIT key to exit.

GPS5 - RAIM Status Screen (for RAIM Enabled

Models Only)

RAIM (Receiver Autonomous Integrity Monitoring) is a standard feature in the MX500 CDU. The RAIM feature is mandatory for IMO compliant vessels. It alerts the operator that a condition may exists in the GPS positioning solution that reduces the desired accuracy of the ship’s position.

This feature requires at least five or more GPS satellites to operate properly, four satellites or less are considered to be a caution or unsafe RAIM condition. If the statistical RAIM error exceeds a selected limit (100 meters default) a “RAIM Unsafe” or “RAIM Caution” alarm will be indicated in the MX CDU.

This means that the the RAIM estimated position error is equal or greater than the preset limit. The operator is advised to take extra precautionary measures when using the navigation solution until the RAIM indicator switches to “RAIM safe” condition. When less than 5 satellites are receivable a “RAIM Caution” will be indicated.

The GPS5 screen shows the position Lat/Long, height of antenna, HDOP, number of satellites used, the satellite ID number that may cause the statistical error and its bias

Simrad MX500 | 105

value. It also shows a table containing the PRN numbers of satellites in use, their residual errors and elevations.

Below it is the RAIM Status indicator and time. The RAIM icon is shown on the top-right corner of the display.

Position errors may be caused by unhealthy satellites, incorrect pseudoranges, poor DGPS corrections and excessive atmospheric interference. When the RAIM caution or RAIM unsafe alarm is on, the GPS/DGPS accuracy may be degraded but still usable when navigating in open waters.

When the RAIM option is enabled an icon is posted on the top right corner of all screens.

- means RAIM safe condition

- means RAIM Unsafe condition, position errors exceeded the range limit specified under the CFG/GPS/

Accuracy Rng.

- RAIM Caution. Not enough satellites are available for proper RAIM calculation.

The GPS5 RAIM Status screen is available in MX500 models with program version 3.0 and using the MX421,

MX521A, MX525A or MX575A antenna sensors.

The MX500 and RAIM feature is an aid to navigation ONLY. Under no circumstances should it be used in lieu of authorized government charts. Its accuracy can be affected by many factors such as equipment defects, environmental conditions, or improper operation. The user is responsible for safe navigation of the vessel. This includes consulting authorized government charts and exercising common prudence and navigational judgement at all times.

GPS6 - DGPS STATUS

There are several windows in this display, the left hand windows are divided into control and configuration windows. The right hand window displays all the corrections that are being received. Shown below is the GPS6 screen.

MX500 GPS6 Screen

Status will tell you whether the correction data is being decoded is error free or not. Normally, Status will indicate either DGPS mode Off, DGPS OK, Tracking or

Searching (Automatic search mode) or No Lock (Manual tuning mode). DGPS OK indicates that RTCM SC-104

DGPS corrections are being received without errors within the Age Limit set in CFG1 DGPS.

These information originates from the MX421B beacon receiver. Searching indicates that the beacon receiver is searching for the appropriate frequency and/or modulation of the beacon transmitter in automatic search mode.

No lock indicates that the beacon receiver is not receiv-

Simrad MX500 | 107

ing DGPS corrections from the selected station in manual tuning mode. You might see the label Tracking, which indicates that a MSK beacon signal is present but DGPS corrections are not being received. This is usually caused by high noise on the beacon receiver or external device.

If you press the EDIT key, you can select between

Automatic beacon search mode, Manual beacon tuning mode, or Off. When the receiver is in the Manual tuning mode, you can use the cursor key to scroll down into the large window below Station Selection and edit the Reference Station name. The name you enter will always be associated with the frequency to which you programmed the receiver. If you move to another region that uses a frequency and name you previously entered, the receiver will display the previously entered name.

You can enter a new name for any manually tuned frequency at any time.

Use the cursor key to move down the screen again and program the frequency you desire. The receiver will automatically update the Station ID. If the beacon station is transmitting its location, the receiver will calculate the distance between the reference station and the receiver, otherwise this will be blank. You can usually find current beacon status, location, and operating information from the governing country’s Coast Guard or Maritime Safety

Administration. You will find a list of known beacon stations in Appendix B - Beacon List at the end of this manual. This list may be incomplete at your location, in which case we encourage you to contact the appropriate governing agency.

108 | Simrad MX500

When you are in manual tuning mode, pressing the EDIT key will bring up the cursor on the Frequency. You can only complete the manual tuning operation by pressing the EDIT key when the Frequency is highlighted.

Program the frequency you desire and press the EDIT key. The CDU will automatically update the Station ID.

If the beacon is transmitting its location, the CDU will calculate the distance between the reference station and the receiver.

You can usually find the current beacon status, location and operating information from the governing country’s

Coast Guard or Maritime Safety Administration. You will find a list of known beacon stations in Appendix B -

Beacon List at the end of this manual. This list may be incomplete, in which case we encourage you to contact the appropriate governing agency.

Once you have entered the data for several beacon stations, you can cycle between these stations by pressing the Next Station or Previous Station softkeys. These softkeys are only displayed if you have entered a name for the reference station.

The window on the right side of the display indicates which satellite ID’s are receiving corrections. When the

PRN number is shown in inverse video, this indicates that the receiver is using the correction in the navigation solution. The Corr value is the actual satellite range measurement correction, given in meters. This value is typically between -20 and +20. The Age value indicates how long it has been since the satellite range correction was generated, given in seconds.

Simrad MX500 | 109

GPS7 - DGPS Messages

This screen will display the Type 16 messages received from the beacon station being used. These messages may contain information regarding operational problems and status or any scheduled equipment maintenance of beacon stations operating within the general area.

The GPS screens are inactive if an MX antenna is not connected or not detected.

3 Advanced Operation

Configuration

The CFG screen includes setup and control of all of the receiver’s primary functions. There are more than 20 separate configuration items in this screen. The display is divided into two windows. The left hand window identifies the primary configuration items. The right hand window displays the current settings. Use the cursor key to select a configuration item of interest, then press the EDIT key to edit the actual settings. There are some settings which can not be changed; however, these are displayed so that you have a better understanding of exactly how the receiver is configured. The Item list is arranged alphabetically based on the language chosen. This section of the manual is arranged alphabetically for English. You may choose to skip to only the items that interest you at first, then read this complete section at a later time.

The configuration list is too long to show in one page of the display. To view all of the configuration menu, scroll through to the bottom of each list with the cursor key.

Alarms

This screen allows you to quickly see which alarms are active and inactive. The list of available alarms is interactive with the remaining screens described in this section.

Therefore, changing the state of the alarm in a screen such as Anchor from Off to On will also cause the anchor alarm in this screen to go from Off to On. Likewise, if you turn the anchor alarm from On to Off in this screen the

Anchor screen will also match this one.

Simrad MX500 | 111

Anchor - Anchor Watch Alarm

This screen allows you to setup an anchor watch alarm and maximum drift radius after you drop the anchor.

The receiver will remember the drop coordinates and provide an alarm if the antenna drifts beyond the maximum distance you entered. If you are on a large commercial ship, don’t forget that the anchor may be several hundred feet from the receiver antenna. You will need to consider this when setting in the distance.

COG SOG - Course & Speed Filter

Settings & Setup

This screen controls the Speed Over Ground (SOG) unit of measure (meters per second, kilometers per hour, miles per hour, or knots). You can also set a filter time to average your speed and course over ground measurements. This helps to smooth these measurements on the display and NMEA output, a particularly useful tool for slow moving vessels. The default filter setting is 2.0 seconds.

112 | Simrad MX500

Compass - External Compass Input &

Magnetic Variation Table

The receiver will accept a magnetic compass input using the NMEA 0183 data record of xxHDT, xxHDG, xxHDM, xxHCC, xxHCD, xxVHW, or any of the above. “xx” refers to the Talker Identifier as specified in the NMEA 0183 standard. The receiver will accept these data records from any talker ID, and from any version (1.5 or higher) of the NMEA 0183 standard.

To implement this feature, change Compass Connected to Yes.

Identify the appropriate input port that the compass connects to the receiver by using the Change softkey.

Select whether or not the receiver should give an alarm if data is not received on the input port.

Select the compass type, either Magnetic, Gyro, or

MX575A. Only the NMEA 0183 records identified above are accepted for the gyro input.

Magnetic:

Select the magnetic deviation method: either In Compass

- the deviation is corrected before being sent to the receiver; or In Navigator - the deviation is corrected by editing a deviation table (Edit Table softkey) in the receiver.

Simrad MX500 | 113

Gyro:

Set the constant Gyro Heading Offset (or bias) if any.

Specify the input NMEA 0183 record for the Input

Sentence. HDT, HDG, HDM, HCC, HCD, VHW, or Any.

MX575A:

Set the constant MX575A Heading Offset (or bias) if any. If the MX575A is used as a positioning and heading device, set Data input port no: to 3. If the MX575A is used as a heading device only, set Data input port no: to any available port (1 or 2) other than port 3 (See MX575A

Satellite Compass Installation & Operation Manual for

details).

Datum - Current Position Calculation

This screen controls which datum the receiver uses to display any position. There are over 100 datums to choose from. Appendix A provides a complete list of available datums. You can enter an offset to WGS-84 if your specific datum is not provided for in the receiver.

Use the Previous or Next softkeys or the cursor key to scroll through the list until you find the datum you need.

Highlight Escape then press ENT to go back to the original datum displayed when you first pressed the EDIT key.

114 | Simrad MX500

Depth - NMEA Input Control

This screen allows you to configure the depth unit (meters, feet, or fathoms) for the NAV 4 and TIDE 1 screens.

Depth information is accepted by the receiver from the

NMEA 0183 data sentence DBK, DBS, DBT, or DPT on any input NMEA port. Refer to the Installation section of this manual for hardware interface instructions.

Press the EDIT key and move the cursor to the Echo

Sounder Connected line. Use the Change softkey to activate the input data options described below:

Depth Unit - select between meters, feet, or fathoms.

This data field sets the depth unit displayed in NAV 4 and

TIDE 1, regardless of whether a sensor is connected or not.

Echo Sounder Connected - causes the receiver to look for one of the appropriate NMEA 0183 data sentences when set to Yes.

Data Input Port No. - Select the appropriate NMEA 0183 port that the sensor is connected to (Port 1 or 2). Ports

3 and 4 are reserved for the MX antenna controls.

Offset - Input the appropriate offset for the sensor, based on the measurement you are most interested

Simrad MX500 | 115

in. If your boat draws about the same amount of water each time you use it, you may want to put in the difference between the sensor and the waterline height. If your boat’s draught changes from one trip to another, as would be the case when the receiver is used on a freight ship, you may want to put in the difference between the sensor and the lowest point of the ship’s hull.

Shallow Alarm Active - allows you to receive an alarm if the sensor receives depth data lower than the limit you set in Alarm Limit (below). The default setting is No.

Alarm Limit - allows you to specify at what depth you want an alarm to activate. This alarm limit is enabled by the Shallow Alarm Active selection of Yes.

Alarm If No Data - Allows you to receive an audible and visual alarm if NMEA 0183 data is not being received on the data port at regular intervals (typically every few seconds). The available choices are Yes (default) and No.

Input Sentence - Specifies the NMEA 0183 data sentence to read the depth data from. The available choices are

Any (default), DPT, DBS, DBT, or DBK sentence. It is better to specify the appropriate sentence because more than one method of reporting depth may be available on the port.

The window in the lower portion of the screen allows you to see the depth data that is received on the data port

(Input:) and the data that is actually displayed in NAV 4

(Used Value:).

DGPS - DGPS Configuration

This screen controls the built in beacon receiver in the

MX smart antenna unit.

116 | Simrad MX500

Internal Beacon Menu

DGPS Mode:

Auto - sets the receiver to automatic DGPS or GPS modes. This is the default setting. If DGPS corrections are being received and their age is less than the Max Age limit, the receiver will operate in DGPS mode (assuming you are receiving corrections for enough satellites to operate in DGPS mode). Otherwise, the receiver operates in GPS positioning mode.

The traffic light will be green when it is in DGPS mode.

Then it drops to GPS mode, a DGPS symbol will be displayed (indicating Non Differential GPS mode), and the yellow and green traffic light will be on.

Use this mode when maximum navigation coverage is more important than accuracy. Reverting to GPS mode will degrade the overall navigation results, but it is better than no navigation results at all in most circumstances.

DGPS Only - sets the receiver to only provide DGPS position fixes. If corrections are being received and their age is less than the Max Age limit, the receiver will operate in

DGPS mode (assuming there are enough corrections to operate in DGPS mode). Otherwise, the receiver will not provide any position fix at all.

Use this mode when accuracy is more important than maximum navigation coverage. When operating in this mode, you should also set the Max Age to 30 seconds.

Off - sets the receiver to operate in GPS mode only.

Max Age -sets the maximum time limit that the last received DGPS correction will be applied to the satellite range measurement in the receiver. The default setting is 60 seconds. The receiver will accept values from 10 to 999 seconds. Due to the removal of the S/A dithering from the satellite signal, you may now use values of 300 seconds in the maximum age and still be very accurate.

Message 16 Alarm - sets the alarm to On or Off if a reference station text message is received. The default setting is Yes. Received Type 16 messages can be displayed on the GPS7 screen, regardless of the alarm setting.

Alarm For No Corrections - sets the alarm to on or off if

DGPS corrections are not received within the Max Age.

Simrad MX500 | 117

The default setting is Yes. If the alarm is set to Yes, you should notice that the receiver drops out of DGPS mode and into the mode selected in DGPS Mode described earlier in this section at the same time the alarm sounds.

Alarm on health change - Sets the alarm to On or Off if the satellite becomes unhealthy or unusable.

WAAS/EGNOS enabled - sets the source of differential correction to come from satellite based augmentation system such as US-WAAS or European-EGNOS system.

Although this systems are available, they are still not considered as IMO compliant systems. Use of these differential correction sources should be done with great caution.

External DGPS Enabled - gives the user the capability to accept RTCM SC-104 corrections from an external beacon receiver (Coastguard or a Private Beacon Reference

Station). The MX500 allows you to control the baud rate of SC-104 Data input port. The following baud rates can be used - 2400, 4800, 9600, 19200.

WAAS/EGNOS and External DGPS are available only for the MX521A or MX525A antenna with the MX500 CDU.

DR - Dead Reckoning

DR, or Dead Reckoning, is an added navigation feature of the MX500.

When the DR setting is set to ‘Yes’ and appropriate compass/heading and speed log sensors are connected and activated, the MX500 will automatically switch to DR calculation when the GPS positioning becomes unavailable.

A DR icon on the top right corner of the display indicates that the position displayed is derived from DR calculation.

118 | Simrad MX500

To set the DR to ‘Yes’ press the EDIT key then highlight the ‘Change’ softkey and press the ENT key. Press the

EDIT key again to exit the edit mode.

Dual Control - Dual Station Control

This screen sets the functional control between two or more MX500 CDU’s interfaced together. The default setting is No. When this selection is changed to Yes, one receiver is set to Master, the other receiver(s) is set to

Slave(s). If the MX500 is a Slave, it will have the Repeater option. If Repeater is enabled, the MX500 only acts as a display unit. A Repeater unit does not have the capability to modify any setting unless a password (which is set by the Master unit in CFG1/Security) is entered. These units will share a common database and one antenna. Refer to

Appendix D for more detailed information about the dual control and multiple unit control setup and operation.

CFG1/LAN must be setup before enabling this feature.

A dual control system consists of one Master and one

Slave. A multiple unit control system consists of one

Master, at least one Slave (maximum of two), and up to three (if any) Repeaters. A multiple unit control system must contain a minimum of three MX500 and a maximum of five MX500 units altogether.

In a Multiple Unit Control configuration, this option must be enabled (by changing Dual Control to Yes and press the EDIT key to exit edit mode) for all

Slave and Repeater units before enabling it in the

Master unit.

MX500 Dual Control Menu

Simrad MX500 | 119

GPS - Elevation Mask Control

This screen controls the elevation mask angle, or the angle above the horizon, at which the receiver will attempt to track a satellite. Satellites with an elevation below this angle will be tracked but will not be included in the position solution. You can set the elevation limit to any value up to 90°. For most marine applications, the default limit of 5° is appropriate.

The Antenna Offset allows you to virtually offset your antenna location. That is, if you are forced to place the antenna in a location other than where you want your position fix calculated (due to superstructure or other high power antennas), you can place the antenna in a practical location. Then enter the appropriate Antenna Offset, and the receiver will calculate your position in the place where you would have preferred to place the antenna.

The RAIM menu is normally set to YES. RAIM stands for

Receiver Autonomous Integrity Monitoring. For more information about RAIM, see page 105.

Init Pos - Initial Position Entry

This screen is provided to help the GPS receiver in the

MX antenna to get a faster first position fix. While the smart antenna is capable of computing its position without any user input, this feature can cause a position fix to occur several minutes earlier. Another time this feature is useful is when the receiver has been moved over

300 miles from the last location it was used while in the off condition.

Again, the receiver will calculate a position fix without any user input in this circumstance. However, moving the receiver to a new location and not inputting a new initial position will cause the receiver to select a satellite con-

120 | Simrad MX500

stellation consistent with the last known receiver coordinates. In this event the receiver may “get lucky” and find common satellites between the old position and the new location, or it may take up to 20 minutes to go through all of the constellation possibilities.

Note that the receiver will stay on the original constellation for 15 minutes before attempting other constellation possibilities. We assume the receiver will be turned on and off in the same general area each time, and we provide the unit every opportunity to try and track satellites at the last known coordinates.

LAN - Local Area Network

This feature allows the MX500 to communicate with another MX500 via LAN interface (RJ45). This data link is used by the MX500 for dual control, integrity monitoring, and multiple control applications.

To activate LAN, press the EDIT key and select the

Change softkey to change LAN Enabled to Yes. Use the

Change softkey to modify the options described below:

Type - select between Host or Client. In a dual or multiple unit control system, the Master will be the Host and the Slave(s) will be the Client(s).

Simrad MX500 | 121

Number - this option is only available when Type is Client.

The available values are 1, 2, 3, or 4 (which determines the IP address of the CDU). Each Client has to be assigned with a unique number (1, 2, 3, or 4). Any two or more Clients with the same number will create an IP address conflict, and therefore, will activate an IP Conflict

Alarm. Please refer to the table below for the MX500 IP

Address.

When the connection is successful, the Status will display

ESTABLISHED.

LAN Output (NMEA 0183 OVER IP)

This screen is very similar to the NMEA Out screens. It sets the specific NMEA 0183 output record parameters.

The default setting is No. When this selection is changed to Yes, you can turn on individual data records, and transmit using the Local Area Network (LAN) connection.

This feature can be used to integrate the MX500 to an

Integrated Bridge System by connecting the CDU to a

PC-based IBS system using LAN (RJ45).

CFG1/LAN must be setup before using this feature.

122 | Simrad MX500

LORAN-C Integration

The MX500 has two selections for Loran-C integration (Raytheon and Locus). This feature will be available when the Loran-C license is activated. Please copy the PCB & part number and call SIMRAD to obtain the license.

Raytheon

To implement this feature, change LORAN-C connected to

Yes.

Identify the appropriate input port (1 or 2) that the

LORAN-C device connects to by using the Change softkey.

Select the appropriate Version Number with the range from 0 to 9.

The Antenna offset option of the LORAN-C feature is tied to the Antenna offset from the GPS feature. Note that any changes you make to the Antenna offset in LORAN-C will also modify the Antenna offset in the CFG1/GPS screen. The Antenna offset allows you to virtually offset your antenna. That is, if you are forced to place the antenna in a location other than where you want your position fix calculated (due to superstructure or other high power antennas), you can place the antenna in a practical location. Enter the appropriate Antenna offset, and the receiver will calculate your position in the place where you would have preferred to place the antenna.

After the LORAN-C (Raytheon) feature is enabled, you will have 3 new screens (POS 4, POS 5, POS 6), which display the following information:

POS 4 - GPS/LORAN-C Combined Position

POS 5 - LORAN-C Calibrated Position

POS 6 - LORAN-C Stand Alone Position

Simrad MX500 | 123

The POS 4 screen displays the GPS/LORAN-C combined

position and navigation modes received from the $PMVX1 message (which is based on (D)GPS if GPS is available, and based on (D)GPS calibrated LORAN-C position if

GPS is not available) from the LORAN-C receiver. The

$PMVX1 message is formatted just like the NMEA GGA message, except that its GPS quality indicator ranges from 0-5. The GPS quality indicator is displayed as a navigation mode on the POS 4 screen.

The POS 5 screen displays the (D)GPS calibrated

LORAN-C position received from the GLL message from the LORAN-C receiver.

The POS 6 screen displays the stand alone (uncorrected)

LORAN-C position received from the RMA message from the LORAN-C receiver.

124 | Simrad MX500

When Loran-C (Raytheon) is enabled, the MX500 gives the option to accept EUROFIX DGPS corrections instead of the External DGPS corrections under the CFG1/DGPS

Configuration screen.

Navigation - Navigation Method & Waypoint

Pass Criterion Control

This screen sets the navigation mode to Rhumb Line or Great Circle, Cross-track Error limits and alarms,

Waypoint Pass Criterion, and Waypoint Approach alarms.

These settings have a direct effect on your route calculation and how data is displayed in the NAV and PLOT screens.

130 | Simrad MX500

Navigation:

Sets navigation to Rhumb Line (default) or Great Circle mode.

When the navigation mode is set to Great Circle, the

PLOT screens will not show your course or cross-track error lines.

Range Unit:

Sets the unit of measure for all range calculations. You can choose between Nautical Mile (default), Nautical Mile

& Meters, Nautical Mile & Feet, Statute Mile, Statute Mile

& Meters, Statute Mile & Feet, Kilometers, and Kilometers

Direction:

Sets all displays which indicate direction to True or

Compass. If you want the receiver to agree with your magnetic compass, select Compass. The receiver will automatically add or subtract the appropriate magnetic variation and deviation. Enter the compass deviation table into the receiver in this screen. You can differentiate between True and Compass settings by observing the degree symbol on any bearing or heading display. True is indicated by a degree symbol (°), Compass is indicated by a degree symbol with a small c under the symbol ( c ).

Simrad MX500 | 131

XTE Limit:

Sets the distance left or right from the course line you consider to be the maximum allowable off-track error

(known as cross-track error, “XTE”). The PLOT screens will display the scaled cross-track error distance. The

NAV screens will indicate the cross-track error in numerical format and present the cross-track error graphically scaled left or right of the course line.

XTE Alarm:

Causes an alarm to sound if your position exceeds the maximum XTE Limit defined above when Yes is selected.

To disable the alarm, select No (default) with the Change softkey.

WPT Pass Criterion:

Sets the waypoint passed determination method. There are five methods available:

Complex:

This is the default setting. Passing the waypoint is determined by reaching an imaginary perpendicular line.

Or you can pass the waypoint by crossing the bisector line of an acute angle (providing you are within 0.2 NM of the waypoint) or an obtuse angle between your present course line and the next leg of your route.

Manual:

Passing the waypoint can only be accomplished by manually skipping a waypoint. Refer to the Skipping and

Unpassing Waypoints in the Route section of this manual.

This is a great way to perform station keeping maneuvering. Refer to the Plot Screen Use Examples in the Plot section for further details on this application.

132 | Simrad MX500

Distance:

Passing the waypoint is determined by reaching an imaginary circle around the waypoint, the radius of which you can define in WPT Pass Distance. The default value is

0.10 Nm.

If you set this distance to 0.00, you will never pass the waypoint. This is a great way to perform station keeping maneuvering. Refer to the Plot Screen Use Examples in the Plot section for further details on this application.

Bisector Line:

Passing the waypoint is determined by reaching the bisector line of an acute or obtuse angle between your present course line and the next leg of your route.

Perpendicular Line:

Passing the waypoint is determined by reaching an imaginary perpendicular line from your present course line.

Approach Alarm:

Causes an alarm to sound if your position is within the radius defined in Approach Distance (below) when Yes is selected. To disable the alarm, select No (the default condition) with the Change softkey.

Approach Distance:

Sets the waypoint approach alarm distance (above) to sound if your position is within the radius defined. The default setting is 0.30 Nm. This is a convenient tool for large boats and ships that need to perform Transfer and

Advance maneuvers prior to reaching the waypoint.

Simrad MX500 | 133

Autopilot Alarm:

Causes an alarm when your position is outside the crosstrack error limit defined in XTE Limit (above) or when you change course to a new leg in your route (manually or automatically passing a waypoint) when Yes is selected.

It also causes the NMEA data records of APA, APB, and

XTE to change their reported status of Valid to Invalid when you reach the waypoint of the current leg. This tells the autopilot not to use the data from the receiver.

When the alarm is canceled, which requires your highlighting of the Cancel Alarm softkey then press ENT

(displayed during the alarm condition), these data fields will revert to valid data and the autopilot will accept the receiver data again. This is provided as a safety feature so that the boat does not turn toward a new direction without your knowing of the impending change. To disable the alarm, select No (the default condition) with the

Change softkey.

NMEA Out 1 and 2 - NMEA 0183 Output Data

Control

These screens set the specific NMEA 0183 output record parameters as well as the port control. The default setting is No. When this selection is changed to Yes, you can turn on individual data records. Refer to the installation manual of the device you interfaced with the receiver to determine which output records are required. Refer to the Installation section of this manual for receiver hardware interface information.

MX500 Model - has two user NMEA ports available, two antenna ports (NMEA3 & 4) dedicated to the MX smart antenna, and one Local Area Network (LAN) port.

Pre plan your interface requirements to ensure all of your interfacing needs are met. All NMEA Ports are RS-422 electrically. We recommend using these ports to interface to a computer or other “single ended” interface.

The default condition of each port is Off. When you want to output data on a NMEA port, scroll down the Item menu to the appropriate NMEA Out port number and change Port Active to Yes. In doing so, the receiver will display all available NMEA 0183 output sentences.

134 | Simrad MX500

MX500 NMEA Out Menu

Scroll down the list using the cursor key to the desired

NMEA 0183 sentence. Highlight the Change softkey then press ENT to select On.

Highlight the Details softkey then press ENT to view the characteristics for the NMEA record you select. If you notice that the top of some text is cut off by the Capacity

Needed window, this indicates that there are more selections available than can fit in the window. Use the cursor key to scroll down the list. Each record is controlled separately. Generally speaking, the following controls are available to you for most or all of the records:

Checksum On or Off - NMEA 0183 version 2.1 and above requires that the checksum is present. Versions 1.5 and

2.0 do not require the checksum. The receiver provides you the option of turning the checksum on or off to provide flexibility in interfacing.

Output Rate - maximum once per second, unless the

Multi-Hertz option is installed. Refer to the Total Load Is section which follows.

All position information contained in any data record is output in the local datum selected in CFG/Position; except GGA, which provides a selection in the Details screen to output in either WGS-84 or the datum selected in CFG/Position.

Simrad MX500 | 135

Most:

NMEA Version - Some of the NMEA 0183 records are no longer supported by version 2.3. However, you may have an autopilot, plotter, or other older model equipment that does not support the newer version of the NMEA

0183 standard. The receiver provides you the flexibility to interface using older versions of the NMEA standard to support these devices.

Decimals In Lat/Lon - The software allows you to select from 2 to 5 decimal places in records containing position or waypoint information. The receiver provides you the flexibility to match the expected input on these devices.

Decimals In BRG or HDG - The receiver allows you to select from 0 to 1 decimal places in records containing bearing information.

xxx loads the port by - The NMEA 0183 standard limits the port baud rate to 4800 bits per second. It is impossible to turn on every NMEA 0183 data record on one port in the receiver at a once per second output rate, due to the NMEA standard limi tation. xxx loads the port by tells you how much throughput capacity is required to send the selected data record out the port (where xxx is the NMEA data sentence identifier).

If you change the Output Rate, xxx loads the port by: value will adjust to reflect the change after you move the cursor to the next line. This is a very helpful tool to

136 | Simrad MX500

ensure that you don’t lose data due to lack of throughput on the data port.

Total load is - Due to the throughput limitation of the

NMEA 0183 standard, you can not turn on all of the output records available from the receiver at a once per second output rate at one time. The “Total load” counter will help you maximize the port usage on the receiver. It monitors the total throughput capability of all the output records that are currently turned on. If you go over

100% and you require all of the data records that are currently turned on, try reducing the Output Rate for one or more of the less critical data records. Continue this process until the Total load is 100.0% or less.

There are several special case screens which provide added support.

Rnn - Active Route Data Record:

The NMEA-0183 standard allows you to output the active route with an ID sentence that begins either as GPR00 or

GPR01. Some of the equipment you might interface may require this sentence to outputs R00 and other equipment may require this data record as R01. The receiver allows you to configure the ID either way (R00 is the default).

WPL - Waypoint Location Data Record:

The receiver outputs all of the waypoints in the active route. If you want to output the complete Waypoint

Bank, simply high light the Send All softkey then press

ENT from the NMEA WPL screen.

Simrad MX500 | 137

The WPL record, as defined by the NMEA 0183 standard, technically does not allow the output of waypoint descriptions when interfacing to other devices such as Chart Plotters. However, SIMRAD realizes that with

2000 waypoints, you have spent a lot of time preparing your library of waypoints with definitions and symbols.

You probably will want to record these to a PC, just in case the memory in the receiver fails in the future. For this reason, we have provided you the option to Include

Waypoint Names in the WPL record to save your waypoints to a PC or to meet the NMEA 0183 standard for interfacing to other marine equipment. The definition of the differences between these two formats is given in the

Basic operation section and in the Installation section of this manual.

138 | Simrad MX500

Other Special Cases Affecting NMEA 0183

Records:

BWC, BWR, APA, APB, RMB, RMC, and Man Over Board

(MOB):

During the period when the Man Over Board function is activated, NMEA 0183 records which contain bearing and range data, such as those identified above (but not limited to these), will reflect the bearing and range back to the MOB position until the MOB function is canceled.

Refer to the MOB section of this manual.

APA, APB, XTE, and the Navigation Autopilot Alarm:

Refer to the CFG Navigation section. When the Autopilot

Alarm is set to No, the receiver always indicates a mode

‘A’, or valid data to the autopilot or other marine device which might be receiving this data. If the Autopilot Alarm is set to Yes, then the receiver changes the mode ‘A’ to

‘V’, indicating invalid data when you reach a waypoint or exceed your cross-track error limit set in the CFG

Navigation XTE Limit field. When the alarm is canceled, which requires your highlighting of the Cancel Alarm softkey then pressing ENT (displayed during the alarm condition), these data fields will revert to Valid data and the autopilot will accept the receiver data again. This is provided as a safety feature so that the boat does not turn toward a new direction without your knowing of the impending change.

Output Port Configuration Conflicts:

The NMEA output ports can only be assigned once. If you have already defined a given port for one format, and you attempt to define a different format for the same port, the receiver will warn you of the port conflict. The first format to be defined on a port maintains the port.

The second format will be ignored.

Simrad MX500 | 139

Operation - General Setup and Control

Settings

This screen controls a few basic operating settings:

Remember Display: When set to Yes (default), the receiver remembers the Page Number or screen you viewed the last time you used a particular function. For example, if you normally monitor the NAV3 display and you decided to look at the PLOT1 screen, the next time you press the NAV function, the receiver will automatically revert to the NAV3 screen immediately.

If you select No for Remember Display, the receiver will always display the first page of a function when you press the function key.

Edit Timeout: You can set the timeout limit between

None (default), or 1 to 10 minutes. If you enter the edit mode on any screen and have a timeout period other than None, the receiver will automatically exit the edit mode if no keys are touched and the timeout period expires.

Preceding Zeroes: Places zeroes (0s) before directions less than 100° when Yes is selected. For example, 079°.

Otherwise directions are shown without the leading zeros when No is selected (default). For example, 79°.

Beeper: If you attempt to perform a key function that is not allowed, you normally hear an Error Tone. This is performed when the Beeper is set to On (default). If you don’t want to hear the error or any other keyboard beep, set the Beeper to Off.

Retain External Alarm: Allows the CDU to hold the external alarm while the alarm condition still exist. When

Retain external alarm is set to On, the external alarm will normalize only when the cause of alarm is corrected.

140 | Simrad MX500

Engineering Display: This enables an expanded series of display screens in some of the functions. In general, these screens are used by the technician during troubleshooting or by SIMRAD engineers during development testing. Screens which are relevant for troubleshooting are described in Installation section of this manual. The default setting is No. If you should enable these screens, the receiver will automatically turn them off the next time power is cycled on the unit.

Demonstration Mode: This enables the receiver to function as though you are under way, even though you are completely stationary. The default setting is No. When set to Yes, all three Traffic Lights will be illuminated, and a D symbol is displayed in the upper right corner of every display. Generally speaking, this feature is used by

SIMRAD and your dealer for show room or trade show demonstrations. However, you can use it as a training tool until you become familiar with the receiver. As a safety feature, you can not use it to output NMEA 0183 records on the data ports to test and demonstrate other devices such as autopilots, chart plotters, and radars.

Refer to Appendix E of this manual for a full description of the Demonstration Mode.

Organizer - Automated Message Reminders

This screen enables you to program the receiver with up to 25 different message reminders (up to 30 characters in length). You can program it to alarm for shift changes, log entry intervals, medication intervals, weather fax updates, etc.

When the Organizer alarm is activated, the voltage on the Alarm Output Port is also activated. If you have other devices connected to this port, you might need to consider what other systems will be affected when the alarm sounds. SIMRAD offers an External Alarm control software option. Check with your dealer or SIMRAD for details on this software package.

Simrad MX500 | 141

The setup is straight forward. Use the Change softkey to increment forward through the available choices. Use the Go Back softkey to increment backward through the available choices. You can also use the left and right cursor keys to accomplish these same operations. Enter text the same as you do for the waypoints and routes. Use the numeric key pad to enter the appropriate time. Don’t forget to set Message Active to Yes when you are finished editing, to enable the alarm.

Position - Positioning Reference, Mode, &

Alarm Control

This configuration screen controls several important parameters which determine your present position.

Reference System:

This setting controls the coordinate system used to display your position. The available choices are Lat/Lon

(default) or UTM (Universal Transverse Mercator). The receiver will automatically convert any waypoint in the

Route Bank or Waypoint Bank when a different coordinate system is entered. Note that when you select a coordinate system other than Lat/Lon, data in the NMEA

0183 records will remain in the Lat/Lon format, as defined in the NMEA 0183 standard.

142 | Simrad MX500

When you select UTM, you can set the Zone yourself

(Man), or let the receiver calculate the zone for you

(Auto, default).

Alarm For High HDOP:

This allows the receiver to create an alarm for HDOP values which rise above a number that you determine. This indicates that position accuracy is becoming bad, due to poor satellite geometry relative to your position and/or the number of satellites currently under track. You may want to set the alarm to Yes if position accuracy is critical to you. Otherwise this alarm is normally set to No.

HDOP Alarm Limit:

Sets the HDOP value which will cause the alarm to sound.

The default value is 4. The valid range is from 1.0 to

9.9. The higher your HDOP value, the more error you will have in your position fix. Refer to the GPS1 Current

Satellite Status section of this manual for more information about the HDOP value.

Alarm If No Update:

This setting causes an alarm when you stop calculating a position fix for a few seconds when set to Yes (default). A setting of No disables the alarm when position fix can not be obtained.

Printout 2 - Printer Output Control

This menu item controls the printer output sometimes required for commercial shipping. The interface is accomplished on NMEA Out 2 port. The printer output is simple ASCII text designed to operate on any serial line printer, including narrow column printers.

The receiver has two print formats, namely: Full or Brief.

Simrad MX500 | 143

A sample of the Full printer output format is given below:

‘No’ value would allow the MX500 to use ROT data from any available port other than Port 3 when the MX575A is used as a heading device only (See MX575A Satellite

Compass Installation and Operation

Manual for details).

146 | Simrad MX500

Security

The Security screen allows you to lock out the EDIT key in order to keep crew members or visitors from changing settings that you have made. Once this feature is enabled, a press of the EDIT key will require the correct password to gain access. To disable the security functions, you will be prompted to enter a 5 digit password.

You will then be prompted to reenter the password. The security function is then disabled until you enter a new password through the CFG1 Security screen again. Be sure to keep your password in a safe place. If you lose your password, you will need to call the factory to reset the security feature.

Serial I/O

This menu provides a means to verify the status and baud rate settings of all the NMEA ports. Note that the

NMEA ports 3 & 4 are reserved for the MX antenna GPS and Beacon receiver interface. You have no control in these two ports. You can not change the baud settings in its original values.

MX500 Serial I/O Menu

Simrad MX500 | 147

Time - Mode and Format Control

This menu item sets the method in which time is displayed on the receiver.

Time System: Sets the time to UTC (default) or Local.

When Local is selected, several parameters associated with local time are displayed.

Time Format: Sets the time to either a 24 Hour (default) or 12 Hour clock.

Time Offset: Sets the local offset to UTC time. 0:00 is the default.

Summer Time: Sets the local clock ahead one hour in the summer for daylight savings time when set to Yes, or to the Local Offset time when set to No.

The adjusted time value is displayed in the lower window so you can verify the current time without having to leave the screen.

USB - USB Mass Storage Configuration

This option controls the saving and restoring of your waypoints, routes, and system configuration via an external USB device. In the event where you do a software upgrade for your MX500 CDU for example, all your waypoints, routes, and system configuration will be lost.

This option allows you to save them to a USB device (i.e.

148 | Simrad MX500

USB flash drive) beforehand, and restore them from your

USB device after the software upgrade is completed.

This way, you do not have to manually re-enter all your waypoints, routes, and system configuration settings.

To implement this feature, plug your USB device into the USB port of the MX500 CDU first, and change USB

Connected to Yes. Allow a few moments for the CDU to read and detect your USB device. Ensure that status displays Connected before continuing.

Select the data type, either Waypoints, Routes, Config, or All by using the Change softkey.

Waypoints:

This sets the CDU to save (Save to USB softkey) or restore (Restore softkey) your waypoints using your USB device.

Routes:

Select routes will set the CDU to save (Save to USB softkey) or restore (Restore softkey) your routes using your

USB device.

Config:

Allows the CDU to save (Save to USB softkey) or restore

(Restore softkey) your system configuration settings using your USB device.

All:

Allows the CDU to save (Save to USB softkey) or restore

(Restore softkey) your waypoints, routes, and system configurations all at once.

Simrad MX500 | 149

If you are finished using this feature and wanted to remove your USB device from the CDU, ensure that USB

Connected is changed to No and press the EDIT key once more to exit EDIT mode before removing the device.

Please format your USB device using FAT32 file system before use. Refer to page 192 for formatting procedure and hardware compatibility list.

Wind

The receiver will display wind information in the NAV4 screen when connected to a NMEA 0183 sensor which can provide the MWV or VWR sentence.

Data Input Port: 1 (default) or 2.

Wind Speed Unit: miles per hour, meters per second, knots, kilometers per hour.

Alarm If No Data: Allows you to receive an audible and visual alarm if NMEA 0183 data is not being received on the data port at regular intervals (typically every few seconds). The available choices are Yes (default) or No.

AWA Offset: Allows you to input a constant angle correction value.

AWS Correction Factor: Allows you to input a wind speed correction factor.

Input Sentence: Specifies the NMEA 0183 data sentence to read the depth data from. The available choices are

Any (default), MWV, or VWR sentence. It is better to specify the appropriate sentence, because more than one method of reporting wind may be available on the port.

150 | Simrad MX500

Wpt & Rte Input - Uploading Waypoints into the Receiver

This screen enables the input data port to receive waypoints and routes from a chart plotter, PC (VMS), or other device to the receiver. You can receive this data through any of the user NMEA 0183 input data ports.

Load the WPL sentences first, then the RTE sentences.

Change Transducer Connected from No (default) to Yes and select the appropriate port. Refer to the Waypoints -

Uploading Waypoints from Other Devices section of this manual for more details on the software interface.

Turn the WPT & RTE In option to No after the waypoint and route banks have been downloaded to prevent an inadvertent change of the MX500 memory bank.

Installation notes

General

The MX500 Control and Display Unit (CDU) is splashproof and can be installed both above and below deck. To ensure that the back of the display unit remains splashproof, protection covers must be used around the connectors. The installation should meet the requirements of the helmsman, the crew or other users. To flush mount, use the optional flush mount bracket. Ensure that the navigator is mounted in a dry place or where water flows off easily. Avoid places where water may accumulate for any period of time.

Electronic Connections

Refer to figures for the mechanical drawings of the display console and for the electrical interface cables. The

MX500 has four connectors at the back, namely;

Power/Data Connector (12-Pin) (included)

Wire Preparation Procedure

Power/Data (12-pin) Cable:

This is a 6-pair twisted cable. We recommend that the main cable insulation (black plastic) be stripped about 5 inches back to expose the color-coded leads. Below are the color and signal designation of the wires:

Pin 1 --- Red ----------- +10-32 VDC

Pin 2 --- Black -------- Negative GND.

Pin 3 --- Blue ------- NMEA TX1-

Pin 4 --- Brown ------- NMEA TX1+

Pin 5 --- Orange --------- NMEA RX1-

Pin 6 --- Green ------ NMEA RX1+

Pin 7 --- Yellow -------- NMEA TX2 -

Pin 8 --- White ------- NMEA TX2+

Pin 9 --- Purple ---- NMEA RX2-

Pin 10 -- Grey ------ NMEA RX2+

Pin 11 -- Lite Green -- GND Fast Channel IN

Pin 12 ------------ GND

Strip the individual wire insulation about 1/2 inch to make it more convenient to connect the wires to a terminal strip posts. Use electrical tape or shrink tubing to protect exposed shield wires. Use a 20-position terminal strips to terminate the Pwr/Data and Auxilary cables.

This item is not supplied with the product, we suggest getting it from a local electronic store.

Simrad MX500 | 169

Auxiliary (8-pin) Cable:

This is a 4-pair twisted cable. Below are the color and signal designation of the wires:

Pin 1 --- Yellow ------- Ext. MOB Input

Pin 2 --- Green -------- GND.

Pin 3 --- Blue ----------- Dry Contact 1

Pin 4 --- Purple -------- Dry contact 2

Pin 5 --- Grey ----------- Speed Log IN +

Pin 6 --- White --------- Speed Log IN -

Pin 7 --- Orange ------- Speed Log Out +

Pin 8 --- Brown --------- Speed Log Out -

An optional Junction Box with all wires installed is available for easy plug & play installation.

External Power

The MX500 will to operate on 12 ~ 32 VDC supply. It can tolerate voltages no lower than 10 volts and no higher than 35 volts. It draws about 1 Ampere at 12 VDC (with an antenna connected). Power wire colors are red (+) and black (-). Even though the navigator has a reverse polarity protection device, we recommend that the installer observe proper polarity before hooking up the power leads. It is recommended using a 2 amp. fuse in line with the red wire as close to the battery as possible. This not only protects the navigator but also the cabling.

Navigator Grounding

The internal electronic circuits of the navigator are isolated from the external power supply. Connect the ground stud to ship’s seawater ground to avoid static charge build up.

‘Seawater ground’ is any electrically conductive material that is directly in contact with sea water.

MX GPS Antenna Installation

Antenna Location

The MX antennas (MX421, MX521 & MXB5) are designed for exposed installation. They should be mounted with a relative clear view of the horizon. Do not, mount the antenna on top of a very tall mast, as this may degrade the COG and SOG calculations, particularly when in DGPS mode. Ensure the antenna is placed outside the beam path of transmitting radar (typically +15° horizontally from the array’s center point) and INMARSAT satcom (A,

B, C, or M; typically +10° from the array’s center point in any of the possible transmitting directions and at least

5 meters from any side lobe or back lobe direction). The

GPS antenna should be mounted below and at least 5 meters away from these types of antennas. Do not place it within 3 meters of a SSB or VHF radios or their antennas.

Antenna Options

Four antenna models can be used with the MX500, namely:

MX421 D/GPS smart antenna

MX521A D/GPS smart antenna

• MX525A D/GPS Sensor

• MX575A Satellite Compass

Wiring hook-up to the MX421, MX521A, and MX525A antenna models are identical. The antenna model is indicated on the serial number tag on the underside of the antenna. The drive voltage to the antenna is 12-32 VDC

+10%, and normally provided by the MX500.

Antenna Connector

The 10-pin connector at the bottom of the antenna housing provides the necessary interfacing between the smart antenna and the MX500 CDU. Refer to the MX antenna wiring diagram shown in pages 163, 166 or 167 of this manual.

External Differential Connection

Differential corrections from an external beacon receiver can only be connected to either the MX421-10 or the

MX521/MX525 GPS model. Connections are done directly through Pins 7 (yellow) and 8 (white) of the antenna cable for the MX421-10, and Pins 9 (purple) and 10 (grey) of the antenna cable for the MX521 and MX525. It will accept the RTCM SC-104 signal at 2400, 4800, 9600, or

19200 baud.

MX500 Navigator Installation

The Navigator or CDU is the primary unit with the integrated display and keypad. The navigator can be mounted using one of two techniques:

Gimbal mount (supplied)

Frame mount (optional)

Each of these techniques are described below. All the hardware necessary to complete Gimbal mount is provided with the MX500. You will need rear panel access to complete these types of mounts. The Frame mount is an option for applications where front panel removal is not desired or rear panel access is not available. The hardware necessary for the Frame mount is sold separately.

It is important to consider the space behind the unit to prevent sharp cable bends before commencing with the installation. A minimum of 200 mm. free space is needed behind the unit for cable dressing.

Gimbal Mounting

A pivot Mounting Bracket including finger screws are supplied with the MX500. Use the two machine screws with the large palm grips to secure the MX500 to the mounting bracket. To adjust the viewing angle, lossen the side crews and then adjust the tilt angle of the display.

Flush Mount Frame

An optional Flush Mounting Frame is available. First, survey and mark-out the location where the unit is to be mounted. Make sure there is a minimum clearance of 200 mm behind the panel. Cut the mounting hole as shown on Figure 4.5. Mount the MX500 to the mounting frame.

Simrad MX500 | 173

Attach all the cable interfaces to the appropriate connectors. Finally, mount the entire assembly to the panel from the display side.

Turning Power On and Off

The navigator is turned on by briefly pressing the key. Please do not keep the key pressed for more than one second, as this will turn the navigator off again when the key is released. This key is also used to turn the power off by either of two methods: a Software Control:

Pressing the key momentarily will display the softkey option boxes (Yes and No). Respond

Yes by pressing the ENT key to turn the navigator off. Selecting No cancels the operation, and returns the unit to normal operation.

b Hardware Control:

Pressing the key for more than 3 seconds, turns the power off under hardware control. The

MX500 can not be turned on again for 10 seconds when this method is used. Attempting to turn the unit on during this 10 second period, will only activate the navigator for as long as the key is not released. This option is not normally used, and is provided as an emergency alternative to the software power control.

If the external power to the unit fails for any reason, the navigator will remember if it was on or off for about 20 minutes. That is if the navigator was on when the power failed and the power comes back within 20 minutes, the navigator will turn itself on again. Otherwise, it will stay turned off until the key is pressed.

174 | Simrad MX500

Equipment Interfacing

Introduction

The MX500 has two user NMEA ports. Anyone of these ports can be used to communicate with other external equipment which utilize the NMEA 0183 standard. All

NMEA interface ports are configured for RS-422 standard. This configuration complies with NMEA 0183 version 3.0 and earlier. The RS-422 electrical interface will almost always work with the older NMEA 0183 version

1.5 electrical interface; both of which are balanced line

interfaces. If for some reason you can’t get this interface to work, use an RS232-to-RS422 interface converter.

Other features available from the MX500 are:

• External Man-Over-Board (MOB) switch input (also used for external Event input)

Pulse Counter inputs for the speed log,

Pulsed Log output.

External alarm

Compass row displays (when connected to an MX575A

GPS Compass)

Refer to the Installation Section of this manual for interface instruction.

External Man Over Board & Event

An external push button switch can be connected between the pin 1 (MOB/Event) input and REF GND of the

AUX cable . Connect the appropriate MOB/Event pins to a

normally open push-button switch.

The Man-Over-Board (MOB) function is activated when the external switch is pressed for 3 seconds. Once activated, the MOB condition can only be canceled from the

MX500 front panel display. Refer to the Operation section of the manual for this operation and more details on the

Man Over Board function. When this switch is pressed for

1 second, this causes your present position and time to be stored as a waypoint in the waypoint bank. A message indicating which waypoint number is used will be displayed on the MX500 screen for up to 5 seconds.

Simrad MX500 | 175

Speed Over Ground Pulse Output

The MX500 can output the GPS calculated speed over ground in a pulse format. Refer to the Specifications section of this manual for signal characteristics.

The pulse output is derived from pins 7 (orange) & 8

(brown) of the AUX cable. The speed log out (+) is the orange wire, while the speed log (-) is on the brown wire.

It is an RS-422 level signal, and may not be compatible with every installation.

To setup the MX500 software, select the CFG1/Log Pulses screen. This screen controls the output port (Pulse) of the speed over ground log output from the MX500 at a user determined pulse rate of 100 to 500 pulses per nautical mile (200 is the pre-selected value). The default condition of the Speed-Over-Ground output is “No” or not active.

External Alarm Output

The MX500 Ext. alarm output connection is on pins 3 and

4 of the AUX (8-pin) cable. They are held open (floating) during normal operations. In an alarm condition, the external alarm pin is switched to ground potential. When an alarm condition is cleared or acknowledged, the Ext. alarm signal will return to open condition automatically

(refer to table below for relay conditions). However, it is possible to retain the external alarm condition by setting the “Retain external alarm:” to ON. At this setting, the external alarm signal can only be cleared by correcting the problem.

NTE Electronics Relay - P/N R14-11D10-12 for use in a

12 VDC supply). The negative ground of the alarm power supply must be connected to Pin 3 (Blu) of the AUX (8pin) cable (refer to the relay diagram below).

NMEA Interface

The MX500 meets the NMEA 0183 version 2.3 electrical standard for marine interface communications with other marine equipment, such as:

Radars, Plotters, Autopilots, Fish Finders, etc.

There are differences in the electrical interface specification between NMEA 0183 version 1.5 (introduced in

1987) and NMEA 0183 version 2.0 and later (introduced in 1994). Some older model equipment utilize RS-232, others use RS-422, and others meet the older version

1.5 specification. In an effort to simplify your interface capabilities, you should take the time to determine which electrical interface specification all of the interfaced equipment meets.

NMEA Interface to other Equipment

The MX500 meets NMEA 0183 version 2.3 electrically, and in protocol. As version 2.1 is not necessarily compatible with the older version 1.5, the differences in hardware are mentioned here to avoid possible conflicts:

Listener:

The listener input works with a threshold of 2 volts compared to the former 4 volt. It is still an insulated input and, in general, there should not be any interface problems receiving data from the older standard.

Talker:

The talker output is a RS-422 output:

NMEA talker output B is active compared to GND or shield of the navigator. In the old version, output B was normally tied to GND or shield.

The maximum drive voltage between the talker A and B outputs is ±6 volt.

Compared to the former 0 to 15 volt output, the negative voltage between the talker A and B output may be a problem on older listeners which do not meet the new standard.

The minimum output voltage may be as low as ±2 volt.

This is not compatible with the former 4 volt input

178 | Simrad MX500

threshold and may be the cause of interface problems. If this is the case, try using an RS-232 to RS-422 convertor to interface with the MX500. This may more likely solve the problem. Otherwise third party conversion boxes may be necessary.

Cables provided for the NMEA signals are shielded pairs.

If extension cables are needed, be sure to use similar shielded pair cables in order to avoid spurious signal radiation. More than one NMEA listener can be connected in parallel to the same NMEA talker. The maximum number of listeners connected to a single talker is dependent on the combined listener input impedance’s, and the capacity available for data throughput.

MX500 NMEA 0183 Sentences

The NMEA Standard provides for asynchronous transmission, with a single Talker and multiple Listeners per line.

Typical use includes information transfer from electronic positioning and navigational devices to autopilots, plotters, terminals, printers, etc.

The NMEA 0183 Standard uses an 8 bit ASCII block oriented protocol, that is not compatible with the NMEA

0180 simple format or the NMEA 0182 complex format due to differences in data format, baud rate and parity bits.

Data Format

Data are transmitted in different sentences, each containing one or more data fields. A field consists of a string of characters immediately preceded by a “,”

(comma) character, except for the first (address) field which is preceded by “$”, indicating the beginning of a new record. Hex 0D 0A <CR>< LF> - end of sentence - must follow the last field in each sentence.

The data fields are identified only by their position within the sentence as determined by the field delimiters (comma). Numerical data fields within a sentence may vary in length from one sentence to another, depending on the precision available.

Data field position is therefore determined only by counting “,” (commas) rather than counting the total number

Simrad MX500 | 179

of characters from the beginning of the sentence.

The last data field is not followed by a comma delimiter.

When a checksum is used, the last data field is followed by an asterisk “*”, indicating that the checksum follows.

The checksum is the absolute value calculated by exclusive -OR’ing the 8 data bits (no start bits or stop bits) of each character in the sentence between, but excluding “$” and “*”. The hexadecimal value of the most significant and least significant 4 bits of the result are converted to two ASCII characters (0- 9, A- F) for transmission. The most significant character is transmitted first.

RMB is transmitted only if an active route is present. Please refer to the Route section of the Operator’s

Manual for details on setting up an active route.

APA, APB and XTE are transmitted only if an active route is present and the Autopilot Alarm in each of these

NMEA sentence setup screens is Enabled and this feature is not in an alarm condition.

Input NMEA 0183 Sentences

The MX500 recognizes version 1.5, 2.0, 2.1, 2.3, and 3.0

NMEA input records. The MX500 can utilize the following input sentence formats:

Depth: DBK, DBS, DBT, and/ or DPT

Position: GLL, RMA, RMC

Speed: RMA , RMC , VHW, VTG or pulses-per-second

Transducer: MMB, XDR

Waypoints: The received WPL data will overwrite the memory content of the waypoint location which is contained in the received WPL sentence

The MX500 does not process the TALKER identifier (first two characters following the $ of NMEA 0183 sentences)

Simrad MX500 | 181

for any NMEA sentences received. Any pair of characters within the NMEA specification are recognized.

The MX500 does process floating numerical formats in the received sentences.

Although the current version of the NMEA 0183 standard requires that a checksum be present, the checksum is not required by the MX500. However, if the checksum is included in the NMEA sentence, the MX500 will reject any sentence where the checksum and data do not correlate.

Viewing Input Data

You can view data being sent to the MX500 by other equipment or loop a MX500 output port back to an unused input port to verify if it is outputting data to other equipment. This is a great tool to use when you are first interfacing equipment.

To activate the Input Data screen:

Press CFG .

Scroll through the menu and select Operation.

Press EDIT and change Engineering Display from No to

Yes.

Press EDIT again to exit the edit mode.

Press the left cursor key until the CFG3 Input Data screen is displayed.

182 | Simrad MX500

Press the up or down cursor key until the proper input port number is selected.

The data that you will see on the screen is unprocessed.

Therefore, if there are errors in the data, you can compare the data against the NMEA 0183 standard. You can also use this screen to verify that data is being received from external RTCM sources or other equipment communicating with the MX500.

Dual Control (Remote) Interface

The Dual Control feature allows you to connect two (or more) MX500s in a Master / Slave configuration where a common database is shared between two (or more)

MX500 control heads. This configuration also allows you to use one antenna connected to the Master unit, for all

MX500s in the network. The remaining data ports, the

MOB /Event input port, and the alarm output ports are still available on each unit for individual use.

Connected

The interface between the two (or more) units takes place over a high speed (100 Mbps) data link. The master unit must be connected to the smart GPS antenna unit (MX421, MX521, MX525, or MX575). The master unit receives the position data then transfer it to the slave unit(s) at a one second rate (the same as the position calculation). Due to the high speed data link, there is virtually no visible position delay between the two (or more) units.

When the two (or more) units are first configured as master and slave(s), the master listens for a configuration polling message from the slave(s). Once the master recognizes the slave’s polling message, the Common

Data Base (see Table below) is downloaded from the master to the slave(s). This function also takes place each time the units are powered up.

However, it continuously compares the “used” solution to the “other” solution. If the “other” solution is better, it will switch to use that position solution. Essentially, the Master mode will transfer automatically to the unit whose position solution is being used for navigation.

Troubleshooting Guide

The MX500 is virtually maintenance free. There are, however, a few important points to note.

Please check your installation carefully before returning the MX500 to the dealer or factory for service. A few troubleshooting tips follow.

The MX500 performs a variety of self tests during normal operation. If a function fails the self test, the navigator will display an Internal Error message every one minute.

Problem Diagnosis

No response:

(Black LCD display and no traffic light)

No external power supply

Check supply voltage

Check for reverse polarity

No keyboard response or partial keyboard response

Check wire installation

Check if external fuse is blown

Corrupted memory

Faulty keyboard

Faulty processor

Return the unit for repair

Battery low alarm External battery low.

Check power supply voltage and installation

No position update; won’t track satellites (Red traffic light blinking for more than

10 minutes)

Jamming by other on- board or adjacent transmitters.

Faulty antenna or antenna cable.

Relocate GPS antenna.

Connect the MX421 power directly to the external 12 VDC supply.

Replace antenna.

No position update; tracking satellites (Red traffic light solid all the time)

Return the unit for repair.

DGPS mode set to DGPS Only and no corrections are being received.

GPS satellite signals weak (satellites dropping in and out).

Check maximum cable length restrictions and cable condition (for weak satellite signal condition).

Return the unit for repair.

188 | Simrad MX500

Problem

All data lost at power up

No DGPS update; not tracking beacon station

No data output to peripheral equipment

Diagnosis

Backup battery is dead.

Replace the internal backup battery.

DGPS mode set to Off, so no corrections are being received.

Station Select is set to Manual.

Faulty antenna

NMEA output data not configured

Wrong NMEA version

Wrong output rate, or format

Wrong electrical standard

Too many data sentences turned on

(throughput overflow)

More than one NMEA talker on the circuit

Faulty port

The MX420 requires the user to enable

NMEA

Return the unit for repair

Memory Backup Battery

The internal real time clock and memory which stores the waypoints, alarm limits, etc., is backed up by a lithium battery. The expected life time is 2 years at 21°

C, but this is based on the temperature the navigator is stored at when not in use. The higher the temperature, the shorter the life and vice versa.

Backup Battery Replacement

Marine electronics dealers or radio supply stores will typically stock the replacement battery, Type TL-5902,

3.6 V (1/2 AA) Lithium battery.

The battery is mounted in a socket located on the MX500 processor board. SIMRAD recommends this service to be done by a qualified service technician.

MX500 PC Interface

The MX500 data ports 1 & 2 are both RS-422 type data interface. If you need to connect the MX500 to a PC we recommend using an RS-422 to RS-232 converter as shown below.

Appendix C - Engineering Mode

The Engineering Display, which is activated in CFG1

Operation, enables an expanded series of display screens in some of the functions. In general, these screens are used by the technician during troubleshooting or by

SIMRAD engineers during testing and software debugging. This section describes what information is relevant to you, or the information we need to help you troubleshoot your MX500.

Information which is not described here is unsupported, which means SIMRAD will not expand or provide any more information than what is provided in this manual.

If you should enable these screens, they will be turned off automatically the next time power is cycled on the

MX500.

AUX7 - Unit Information & Self Test

When the Engineering Display is active, the AUX7 screen adds one line of detail to display the engineering level that is turned on.

In addition, you can press the EDIT function key and run a complete self test by highlighting the Make Selftest softkey then pressing ENT. The first display of the self test is a keypad test. Press each function and softkey once. When you have pressed each once the test will automatically advance to the Traffic Light test. Observe that the three traffic lights go from dim to bright. Highlight the OK softkey then press ENT if they illuminate correctly or Fail if they don’t.

The CDU will go on to conduct a Contrast test. Observe that the display goes through its full range of contrast

Simrad MX500 | 221

from white to black. Highlight OK then press ENT if it varies correctly or Fail if it doesn’t. Next, the CDU will conduct a Backlight test. Observe that the display goes through its full range of illumination. Highlight OK then press ENT if it varies correctly or Fail if it doesn’t.

Then, the CDU will conduct a Keylight test. You may need to dim the lights in the room or shade the keyboard so that you can see the backlights behind the function and softkeys. Observe that the keypad backlights go through their full range of illumination. Highlight OK then press

ENT if it varies correctly or Fail if it doesn’t. Next, the

CDU will conduct a Beeper test. Listen that the internal beeper activates for about a second. Highlight OK then press ENT if it varies correctly or Fail if it doesn’t. Finally, the CDU will conduct an External Alarm test. Listen that the external alarm activates continuously. Highlight OK then press ENT if it varies correctly or Fail if it doesn’t.

Upon completion of the above tests, a Test Results screen will be displayed. In addition to the visual tests which you witnessed, the CDU also performs background tests on the program memory (FLASH ROM), the realtime Clock, and the Serial (NMEA) Ports. These tests check about 90% of the CDU. The items which it does not check are the GPS and Beacon receivers in the antenna.

If one of the background tests fail, you can try clearing the CDU’s memory to see if the problem will clear.

222 | Simrad MX500

However, when you clear the memory (also known as a

Cold Start), you will erase all waypoints and configuration settings. A cold start sets the CDU back to factory default settings.

Otherwise, record the failure(s) and contact your dealer or SIMRAD to arrange for service or repairs. It is possible, but unlikely, that a cold start will correct other failures noted during the selftest. SIMRAD will need the CDU serial number (from the rear panel) and the Software

Version number to help you further.

Press the EDIT key when you are finished viewing the results.

CDU Cold Start - Clearing Memory to Factory

Default

When you Cold Start the CDU, you will erase all of your waypoints and configuration settings. A cold start sets the CDU back to factory default settings. Perform this procedure if the CDU becomes non-responsive, fails one of the self tests described above, or starts acting very unusually.

To perform the cold start:

1 Turn the CDU off use:

. There are three methods you can a Press the On/Off function key and highlight the Yes softkey then press ENT. This causes a software shut down of the CDU.

b Press and hold the On/Off function key for up to

5 seconds, this causes a hardware shut down of the CDU.

2

3

4 c Turn power off at the circuit breaker panel feed or power supply which feeds the CDU. This is the preferred method.

Hold the CLR button down while applying power to the CDU; continue holding the button until you hear a normal key click for the softkey.

Release the button.

Press the POS function key. If the position reads N

00° 00.0000, W 000° 00.0000, then the CDU was

Simrad MX500 | 223

properly reset. If it does not, try the procedure again.

A common source of memory corruption is an aged

Lithium memory back-up battery. This will result in either a slow deterioration of memory retention or it may abruptly dump all its memory.

SIMRAD recommends the battery be changed every 2 to

3 years of operation by an authorized technical dealer.

Marine electronics dealers or radio shops will typically stock the replacement battery, Lithium type TL-5902,

3.6V (1/2 AA).

GPS - GPS CDU Troubleshooting

GPS3 - Visible Satellite Information

This screen provides some basic information about the

MX smart GPS antenna performance, in that it is basically an extension of GPS1 screen. It tells you what satellites are available to track at the moment under the

PRN number. The signal strength of satellites under track is in the second column labeled S/N. The weakest signal strength that the GPS receiver can track is 25. However, any satellite with a signal strength under 32 is considered

troubled, and the GPS receiver will not use that satellite in the navigation solution. Troubled satellites tend to cause position jumps and greatly reduce the accuracy of the GPS position fix.

The EL, AZ, and STA values represent the satellite’s

Elevation and Azimuth, and Almanac Status respectively.

Low signal to noise (S/N) quality numbers may be an indication of local interference from on-board electronic equipment such as Radar, INMARSAT, VHF, SSB and

224 | Simrad MX500

other high power transmitters. Review the installation of the entire system to ensure you have followed proper procedures for cabling, power, and, most importantly, grounding and antenna placement. The majority of these problems will be resolved by better grounding and antenna location selection. Regarding grounding, the water intake for the engine, or any other electrical ground relying on the engine or generator for Earth ground, is not good for the GPS and especially the beacon receiver.

GPS4 - GPS Position Uncertainty

This screen presents a bar graph representing the HDOP for the past 23 hours. If you are trying to do precision work or navigation in the same general area (within 100 miles) as the day before, you can look at this screen to see when the best HDOP periods are. The GPS constellation shifts back 4 minutes per day. That means you can expect the GPS coverage to be virtually the same today as it was yesterday.

The small 1 hour gap in the bar graph represents the

24th hour. The gap is provided to ease the readability of the bar graph for the present time. The dashed line extending horizontally from the 4 represents the current HDOP Limit Alarm, which is set in CFG Position. The current HDOP and VDOP values are given in the upper window.

MX Ant. Reset & CSI Reset Tools

Special tools are available in the MX500 CDU that can be used to reset the GPS and Beacon engines in the MX antenna. Use them only in extreme cases when the GPS or beacon receiver fails or takes too long to lock-on. The

MX Ant Reset” softkey will clear the satellite almanac memory of the GPS engine and reset all settings of the antenna to factory default conditions. The “CSI Reset”

Simrad MX500 | 225

softkey resets the differential beacon board.

MX Ant Reset Procedure:

This procedure will work only under Engineering level mode.

1 Press the AUX key several times to bring up the

AUX7 screen.

Appendix D - Multiple Unit

Control (Via LAN Connection)

Dual Control Configuration:

The Dual Control mode, which is enabled in the CFG Dual

Contrl. screen, allows you to connect one MX500 as a

Master and another MX500 as a Slave unit. This allows a common data base to be shared between the two CDU control heads. This configuration also allows you to use one antenna connected to the Master unit for both CDUs.

The remaining data ports, the MOB/Event input port, and the alarm output ports are still available on each unit for individual use on each CDU. The hardware interface is accomplished by connecting the two units together via the Local Area Network (LAN) port. You can use an

Ethernet cross-over (null) cable or an Ethernet switch.

The interface between the two units takes place over a high speed (100 Mbps) data link. The master unit must be connected to the antenna. The master unit receives the NMEA signals from an MX antenna and pass it along to the slave unit at a one second rate. Due to the high speed data link, there is virtually no visible position delay between the two units.

When the two units are first configured as master and slave, the master unit mirrors to the slave, and the

Common Data Base (see Table D-1) is downloaded from the master to the slave. This function also takes place each time the units are powered up. If you happen to have the CFG1 Dual Control screen active, the status bar will indicate Mirroring during the database update period.

Simrad MX500 | 227

Multiple Unit Control Configuration:

The Multiple Unit Control mode, which is enabled in the CFG Dual Contrl. screen, allows you to connect one MX500 as a Master, up to two MX500 as the Slave units, and up to three MX500 as the Repeater units. The

Repeater unit, however, only acts as a display unit. It has no capability to modify any setting unless a password

(set by the Master unit in CFG1/Security) is entered.

The Multiple Unit Control system must have a minimum of three MX500 and a maximum of five MX500 units altogether (see Table D-3). The system must have one

Master and at least one Slave. This allows a common data base to be shared among the CDU control heads.

This configuration also allows you to use one antenna connected to the Master unit for all CDUs. The remaining data ports, the MOB/Event input port, and the alarm output ports are still available on each unit for individual use on each CDU.

The hardware interface is accomplished by connecting the units together via an Ethernet switch. Refer to LAN

Turning Master and Slave Units Off

Before turning the power off to either the master or slave unit(s), make sure you go to the CFG1 screen and disable the dual control function. If the master unit is turned off while in dual control mode, the slave unit(s) will not be connected to the antenna nor display a position. The unit that remains on will alarm until the data link is re-established, the unit is turned off, or Dual Control is turned off.

230 | Simrad MX500

Dual-Control Integrity Monitoring

The Dual-Control Integrity Monitoing (IM) feature is an optional feature wherein two independently navigating

MX500 units connected as a master/slave configuration can compare their position solutions. The unit that has the best position accuracy becomes the controlling unit.

Its Position, Speed and Course calculations are used for display, navigation and data output. The basic requirements are; they are both MX500 models with each own

GPS/DGPS smart antenna and both have the IM option enabled.

This IM feature can be found under the CFG/Dual Control menu in units that has the IM license. This menu item is normally hidden and will show only when the slave

MX500 unit has been detected.

Appendix E - Demonstration

Mode

This enables the CDU to function as though you are under way, even though you are completely stationary. The default setting is No. When set to Yes, all three Traffic

Lights will be illuminated, and a D symbol is displayed in the upper left corner of every display. Generally speaking, this feature is used by SIMRAD and your dealer for show room or trade show demonstrations. However, you can use it as a training tool until you become familiar with the CDU. You can also use it to output NMEA 0183 records on the data ports to test and demonstrate other devices such as autopilots, chart plotters, and radars.

In the CFG Operation screen, activate the Demonstration

Mode by selecting Yes.

Active Route: causes the CDU to use the route loaded in

RTE1 screen.

Rhumb Line: causes the CDU to follow the bearing you input in this screen under Demonstration COG.

Demonstration SOG: causes the CDU to simulate a speed of up to 99 knots. Slower speeds of 5 to 25 knots provide the best demonstration results.

Demonstration COG: causes the CDU to simulate a course over ground of up to 359.9 degrees when Follow is set to Rhumb Line.

To setup your course, load the desired waypoints into

RTE1. Notice that the CDU loads your point of departure as N 00, W 000.

Simrad MX500 | 233

Before you adjust your position, set your WPT Pass

Criterion to Distance in the CFG1 Navigation screen. To adjust your position, pick a point near your first waypoint. A distance of 1 or 2 miles from the first waypoint is good to start with. Go to the POS1 screen and press

EDIT.

Next, press the NAV function key, then the E key. Press the Reset XTE softkey. Press the EDIT key. This resets your cross-track error and updates the active route in

RTE1 with the adjusted position.

Now just use the CDU as you normally would. You can output NMEA 0183 data records to other devices. Be careful, however, other instruments will interpret the

data as completely valid. So, don’t run the Demonstration

Mode while you are underway and connected to devices that are being used in real time, like your autopilot.
