On Position valid in an enhanced accuracy mode

(WAAS/EGNOS/MSAS/DGPS).

 Flashing means that the LED is turning on and off at a 1 Hz rate - 0.5 seconds on and 0.5 seconds off.

Troubleshooting:

• If the power is on but the yellow LED does not flash within one minute, then no satellites are being tracked. There may be excessive blockage or the AG-Star may be defective. Make sure the AG-Star has an unobstructed view of the sky. Try power cycling the AG-Star.

• If the yellow LED is flashing but doesn’t progress to solid yellow within one minute, then insufficient satellites are being tracked or the signal quality is poor and ephemeris data cannot be received.

Normally, four satellites are sufficient for a valid position as long as they are widely distributed in the sky.

If LED is stuck on blinking yellow, there may be excessive signal blockage or the AG-Star may be defective. Make sure the AG-Star has an unobstructed view of the sky. Try power cycling the AG-Star.

• If the yellow LED is on, but the green doesn’t turn on within five minutes than no SBAS or DGPS positions are available. If you are using SBAS, make sure SBAS is available in your area and that the

AG-Star is configured to enable SBAS positions (SBASCONTROL ENABLE and

SELECTCHANCONFIG). For DGPS, make sure the AG-Star is configured with the correct serial port parameters and to accept the DGPS protocol your area is using and that your data modem is connected and working.

• The green LED blinks when SBAS is detected then it comes on solid when SBAS is enabled. The LED will stay dark if SBAS is not detected.

MKI and PPS Strobes

The Mark Input (MKI) and Pulse Per Second (PPS) strobes provide status and synchronization signals. PPS is a 3.3V CMOS output; MKI is a 5V logic tolerant input. For more information about the PPS and MKI

signals, see Section A.2, AG-Star Specifications on page 44.

Pin-out information can be found in Table 7, AG-Star Communication/Power Cable Pinouts on page 48.

2.2.3

Emulated Radar (ER)

The AG-Star outputs an emulated RADAR signal via the bare wires labeled ER GND and ER_OUT on the

AG-Star cable. See Table 7, AG-Star Communication/Power Cable Pinouts on page 48 for the pin-out details

of this cable.

The ER outputs a logic high of supply voltage minus 0.5 V minimum and logic low of 0.5 V maximum with a rise and fall time of less than 1 ms. The ER output references signal GND and provides logic low output until the receiver’s speed is greater than 1 km/Hr. ER can be configured to operate at one of three distinct frequencies (26.11, 28.12 or 36.11 Hz/km/Hr, with 26.11 Hz/km/Hr being the default value) and with an

effective range from 1 km/Hr to 55 km/Hr for near-horizontal applications. See Section B.5,

RADARCFG Configure the ER Output on page 57 for more information.

2.2.4

Controller Area Network (CAN)

NMEA 2000 is a CAN standard created by the National Marine Electronics Association and designed to support networking in marine applications. It functions over a longer physical distance, and supports more physical nodes than ISO 11783. The relationship between NMEA2000 and SAE J1939 is that J1939 is the standard, while the NMEA 2000 group has added some new messages (called PGNs or Parameter Group

Numbers) and added a new, additional transport protocol called FastPacket. NMEA2000 compliant, for all intents and purposes, means J1939 compliant plus support for new NMEA2000 messages. J1939 is additionally “harmonized” with ISO 11783, a standard for the agriculture industry.

The CAN module is generally not user-interactive. It is activated when a SETCANNAME command (see

page 60) is entered, and after a SAVECONFIG, the CAN module is activated immediately on all subsequent

start-ups. The module supports the following NMEA2000 Parameter Group Message (PGN):

• PGN 129029 GNSSPositionData (1 Hz)

• PGN 129025 GNSSPositionRapidUpdate (10 Hz)

• PGN 129026 COGandSOGRapidUpdate (10 Hz)

 Details about the PGN messages are found in the NMEA2000 specification which can be purchased directly from the National Marine Electronics Association (www.nmea.org/).

Chapter 3 Operation

Before operating the AG-Star for the first time, ensure that you have followed the installation instructions in

Chapter 2, Installation and Setup on page 13. It is assumed that a computer is used during initial operation

and testing for greater ease and versatility.

3.1

Communications with the Receiver

Communication with the receiver typically consists of issuing commands through the communication ports from an external serial communications device. This could be either a terminal or computer that is directly connected to the receiver serial port using a DB-9 connector on the AG-Star multi-cable. If you are using a radio, it connects to another DB-9 connector on the same multi-cable by means of the radio serial cable supplied with the radio. It is recommended that you become thoroughly familiar with the commands and logs detailed in the OEMStar Firmware Reference Manual to ensure maximum utilization of the receiver’s capabilities.

 When power is applied to the AG-Star, the Power LED lights and the AG-Star begins a self test and the boot up process. After the self test and boot up have completed, the command prompt becomes available on the serial port.

3.1.1

Serial Port Default Settings

The receiver communicates with your computer or terminal via an RS-232 serial port. For communication to occur, both the receiver and the computer or terminal have to be configured properly. The receiver’s COM1 and COM2 default port settings are as follows:

• 9600 bps, no parity, 8 data bits, 1 stop bit, no handshaking, echo off

Changing the default settings requires using the COM command. See Section B.2, COM Configure COM

Port on page 51 for details.

The data transfer rate you choose determines how fast information is transmitted. For example, outputting a log whose message byte count is 96. The default port settings allows 10 bits/byte (8 data bits + 1 stop bit + 1 framing bit). It therefore takes 960 bits per message. To get 10 messages per second then requires 9600 bps.

Also remember that even if you set the bps to 9600, the actual data transfer rate is lower and depends on the number of satellites being tracked, data filters in use and idle time. It is suggested that you leave yourself a margin when choosing a data rate (115200 is recommended for most applications).

 Although the receiver can operate at data transfer rates as low as 300 bps, this is not desirable.

For example, if several data logs are active (that is, a significant amount of information needs to be transmitted every second) but the bit rate is set too low, data will overflow the serial port buffers, causing an error condition in the receiver status and loss of data.

3.1.2

Communicating Using a Remote Terminal

One method of communicating with the receiver is through a remote terminal. The receiver is pre-wired to allow proper RS-232 interface with a data terminal. To communicate with the terminal, the receiver only requires the RX, TX and GND lines to be used. Request to Send (RTS)/ Clear to Send (CTS) hardware handshaking is not available. Ensure the terminal’s communications set-up matches the receiver’s RS-232 protocol.

AG-Star User Manual Rev 4 20

Operation Chapter 3

3.1.3

Communicating Using a Computer

A computer can be set up to emulate a remote terminal as well as provide the added flexibility of creating multiple command batch files and data logging storage files. Any standard communications software package that emulates a terminal can be used to establish bidirectional communications with the receiver. For example, HyperTerminal or NovAtel’s Graphic User Interface (GUI) program NovAtel Connect. All data is sent as raw 8-bit binary or ASCII characters.

3.2

Getting Started

3.2.1

Starting the Receiver

When first powered, the AG-Star undergoes a complete self-test. The results of this test can be viewed by connecting to the receiver and requesting the RXSTATUS log. Refer to the OEMStar Firmware Reference

Manual for more information.

If a persistent error develops, contact your local NovAtel dealer first. If the problem is still unresolved, contact

NovAtel directly through any of the methods listed in Customer Support on page 10.

3.2.2

Communicating with the Receiver Using NovAtel Connect

NovAtel Connect is a Windows-based GUI used to access the receiver's many features. The Convert utility is a Windows-based utility that converts between file formats and strips unwanted records for data file compilation. Both are included in the NovAtel Connect PC Utilities bundle available from: www.novatel.com/ support/search/items/PC%20Software .

Launch the NovAtel Connect program and select Device | Open from its main menu. The Open Configuration window appears.

Figure 7: Open Configuration Window

Refer to the NovAtel Connect help file by selecting the Help | Contents menu or pressing F1 while the cursor is in a NovAtel Connect window. Ensure the Console and ASCII Messages windows are open by selecting them from the View menu.

When the receiver is first turned on, no data is transmitted from the COM ports except for the port prompt.

The console window displays a port name:

[COM1] or if connected to COM1 port

[COM2] if connected to COM2 port or through Bluetooth

AG-Star User Manual Rev 4 21

Operation Chapter 3

Any of these prompts indicate that the receiver is ready and waiting for command input.

 1. You may also have to wait for output from receiver self tests. For example, on start-up, the

AG-Star receiver is set to log the RXSTATUSEVENTA log ONNEW on all ports. Refer to the

OEMStar Firmware Reference Manual for more details.

2. If you find that NovAtel Connect is unable to locate your AG-Star receiver, try using a different COM port to communicate to the receiver. Once communication has been established, issue the command FRESET STANDARD. You should now be able to use your original communication port again.

Commands are typed at the interfacing computing device’s keyboard and executed after sending a carriage return character which is usually the same as pressing the <Enter> key.

An example of a response to an input command is the FIX POSITION command. It can be as:

[COM2] FIX POSITION 51.11635 -114.0383 1048.2 [carriage return]

<OK where [COM2] is the port prompt, followed by the command entered and [carriage return] is a prompt to press the <Enter> key.

The example above illustrates the command input to the base receiver’s COM2 port, which sets the position of the base station receiver for differential operation. Confirmation that the command was actually accepted is the appearance of <OK.

If a command is entered incorrectly, the receiver responds with:

<Invalid Message ID (or a more detailed message)

 Ensure the Control Panel Power Settings on your computer are not set to go into Hibernate or

Standby modes. Data will be lost if one of these modes occurs during a logging session.

3.3

Channel Configuration

The 14 channels available on the AG-Star are configured by selecting one of eight predefined channel configuration sets using the SELECTCHANCONFIG command. For information about the

SELECTCHANCONFIG command, see page 58.

3.4

Transmitting and Receiving Corrections

DGPS corrections can be transmitted from a base station to a rover station to improve position accuracy.

 The AG-Star can receive RTCM, RTCA, CMR, CMR+, RTCM 2.3 and RTCM 3.0 corrections to resolve DGPS solutions. With the DGPS_TX model upgrade, the AG-Star can transmit non-carrier phase RTCM and RTCA corrections. Contact your local NovAtel dealer for more information. To locate a dealer in your area contact NovAtel Inc.

The base station is the GNSS receiver, which is acting as the stationary reference. It has a known position and transmits correction messages to the rover station. The rover station is the GNSS receiver which does not know its exact position and can be sent correction messages from a base station to calculate differential

GNSS positions. The AG-Star can be used as a base receiver to transmit DGPS corrections or a rover to

receive the same corrections. An example of a differential setup is given in Figure 8, Basic Differential Setup on page 23.

For an AG-Star receiver with Bluetooth, one of the serial devices connects through COM1 and the other devices must connect through Bluetooth.

System biases can introduce errors, refer to An Introduction to GNSS found on our web site at www.novatel.com/an-introduction-to-gnss/ for more information. In most cases, a data link between the base station and rover station (two NovAtel receivers) is needed in order to receive corrections. SBAS corrections can be accomplished with one receiver and are exceptions to the base/rover concept. Generally a link capable of data throughput at a rate of 9600 bits per second, and less than 4.0 s latency, is recommended.

Once the base and rover are set up, configure them as shown in the configuration examples that follow in

Section 3.4.1, Base Station Configuration on page 24 and Section 3.4.2, Rover Station Configuration on page 25.

AG-Star User Manual Rev 4 25

Operation Chapter 3

3.4.4

Configuration Notes

For compatibility with other GNSS receivers, and to minimize message size, it is recommended that you use the standard form of RTCA, RTCM, RTCMV3 or CMR corrections as shown in the previous base and rover examples. This requires using the INTERFACEMODE command to dedicate one direction of a serial port to only that message type. When the INTERFACEMODE command is used to change the mode from the default, NOVATEL, you can no longer use NovAtel format messages.

If you wish to mix NovAtel format messages and RTCA, RTCM, RTCMV3 or CMR messages on the same port, you can leave the INTERFACEMODE set to NOVATEL and log out variants of the standard correction messages with a NovAtel header. ASCII or binary variants can be requested by simply appending an "A" or

"B" to the standard message name. For example on the base station: interfacemode com2 novatel novatel fix position 51.11358042 -114.04358013 1059.4105

log com2 rtcm1b ontime 2

Using the receiver in this mode consumes more CPU bandwidth than using the native differential messages

as shown in Section 3.4.1, Base Station Configuration on page 24.

At the rover station you can leave the INTERFACEMODE default settings (interfacemode com2 novatel novatel). The rover receiver recognizes the default and uses the corrections it receives with a NovAtel header.

The PSRDIFFSOURCE command sets the station ID values which identify the base stations from which to accept pseudorange corrections. This is a useful command when the rover station is receiving corrections from multiple base stations. Refer to An Introduction to GNSS for more information on SBAS, available from our web site at: www.novatel.com/an-introduction-to-gnss/ .

All PSRDIFFSOURCE entries fall back to SBAS (even NONE) for backwards compatibility.

At the base station it is also possible to log out the contents of the standard corrections in a form that is easier to read or process. These larger variants have the correction fields broken out into standard types within the log, rather than compressed into bit fields. This can be useful to modify the format of the corrections for a non-standard application or to look at the corrections for system debugging purposes. These variants have

"DATA" as part of their names (for example, RTCADATA1, RTCMDATA1, CMRDATAOBS, and more). Refer to the OEMStar Firmware Reference Manual for detailed descriptions of the various message formats.

Information on how to send multiple commands and log requests using Windows, can be found on our web site at www.novatel.com/support/known-solutions/ .

3.5

GLIDE

 GLIDE is an optional feature on the AG-Star. You must order a GLIDE capable model to use this feature.

NovAtel’s GLIDE is an optional feature on the AG-Star. GLIDE is a positioning algorithm for single frequency

GPS and GPS/GLONASS applications. GLIDE produces a smooth position output tuned for applications where optimal time relative (pass to pass) accuracy is more important than absolute accuracy. Because of this, it is well suited for agricultural applications.

Multipath signals tend to induce time-varying biases and increase the measurement noise on the L1 pseudorange measurements. Carrier phase measurements are much less susceptible to the effects of multipath. The GLIDE algorithm fuses the information from the L1 code and the L1 phase measurements into a Position-Time-Velocity (PVT) solution.

GLIDE includes settings for a dynamic mode, a static mode, and an “auto” mode, where the filtering parameters are automatically adjusted as vehicle velocity varies between stationary and dynamic states.

AG-Star User Manual Rev 4 26

Operation Chapter 3

Refer to the NovAtel white papers at www.novatel.com/support/search/items/White%20Paper for more information on GLIDE. Refer also to application note “APN-038 Pseudorange/Delta-Phase (PDP) and GLIDE

Filters” at www.novatel.com/support/search/items/Application%20Note .

3.6

Emulated Radar (ER)

A typical radar sensor emits radio beams that bounce off the ground and computes ground speed based on the speed at which objects are passing in front of the sensor. The output of the sensor is a digital pulse, the frequency of which is proportional to the vehicle’s ground speed. This is often used in agricultural applications such as planting and spraying. The AG-Star eliminates the need for separate ground-sensing radar equipment by converting the GPS-derived velocity to proportional frequency output. The following emulated radar signal parameters can be configured by the customer:

• Frequency Step: Specifies how the frequency output relates to the vehicle speed.

• Signal Update Rate: Specifies how often the frequency output is updated to match the vehicle speed.

• Response Mode: Specifies how quickly changes in velocity are reflected in the frequency output.

Setting a slower response mode reduces spikes (noise) in the velocity but increases latency.

Setting a higher response mode reduces latency, but may result in noisier frequency output. Refer to

Section B.5, RADARCFG Configure the ER Output on page 57 for more detailed information.

After it is configured using the RADARCFG command, Emulated Radar (ER) pulses are output through the

AG-Star cables (see Table 7, AG-Star Communication/Power Cable Pinouts on page 48) and the

RADARSIGNAL log (see page 63).

WinLoad is the simplest and most common way to update or upgrade an AG-Star receiver.

5.3.1

Transferring Firmware Files

To proceed with an update or possibly an upgrade, obtain the latest version of firmware from the NovAtel website at www.novatel.com/support/firmware-downloads .

5.3.1.1

Types of Firmware Files

The firmware update or upgrade file is one of two types:

Update Version (UPDT) - The update version includes the authorization codes for all AG-Star receivers and receiver model upgrades purchased before the cut-off date 1 . The update version is named UPDTXXXX.EXE, where XXXX is the firmware version. If the receiver or model upgrade was purchased after the cut-off date, the authorization code does not appear in the UPDT file and the

OEM version must be used.

OEM Version - Use the OEM version if the receiver or model upgrade was purchased after the cutoff date. When the OEM version is used, NovAtel Customer Service must generate and provide the required authorization code. Authorization codes are obtained by contacting [email protected]

or at www.novatel.com/support/ .

The OEM version is named OEMXXXX.EXE, where XXXX is the firmware version.

For convenience, copy the update file to a GNSS sub-directory (for example, C:\GNSS\LOADER).

If the firmware update file is password protected, NovAtel Customer Support provides the required password.

After copying the file to a computer, perform the following steps to extract the files:

Syntax: [filename] [password] (if required) where filename is the name of the compressed file (but not including the .EXE extension) and password is the password if required for extraction.

Example: L6X010201RN0000.hex

In the above example, a window appears asking for a password.

The self-extracting archive produces the following files: winload.exe

WinLoad utility program howto.txt

Instructions on how to use the WinLoad utility whatsnew.rtf

Information on the changes made in the firmware since the last revision x..x.hex

Firmware version upgrade file, where x..x defines the product name and release (e.g.,

L6X010201RN0000.hex)

The files are extracted to unzip/program files/NovAtel Inc/x.xxx Full Update Disk, where x.xxx is the firmware version.

 NovAtel has an online video tutorial that explains firmware uploading at www.novatel.com/ support/videos .

1. For further information and the exact cut-off date, refer to the NovAtel website at www.novatel.com/ support/firmware-downloads under notes.

NovAtel Firmware and Software Chapter 5

AG-Star Application Software

The AG-Star receiver has two types of software loaded, the OEM6 firmware and the AG-Star Application

Software. The OEM6 firmware provides the features that are common to all OEM6 receivers. The Application

Software provides the special features available on the AG-Star.

The Application Software is available from the NovAtel website at www.novatel.com/support/firmwaredownloads and is loaded onto the AG-Star receiver using the same procedures used for the OEM6 firmware.

An authorization code is not required for Application Software updates.

5.4

Updating using SoftLoad Commands

Use SoftLoad to update a receiver.

 Use SoftLoad if automated loading is required or the platform used to communicate with the receiver if not supported by WinLoad.

 Refer to Section 5.3.1.1, Types of Firmware Files on page 37 for details on updating versus

upgrading.

1. Open a connection to any port on the receiver.

2. Request the SOFTLOADSTATUSA log using the following command:

LOG SOFTLOADSTATUSA ONCHANGED

.

3. Initialize SoftLoad with a

SOFTLOADRESET

command. This command stops all tracking on the receiver to ensure sufficient memory is available for the loading process. A RXSTATUSEVENTA log reports a SoftLoad In Progress status.

4. Open the *.HEX firmware file.

5. Send each line of the *.HEX file to the receiver in a

SOFTLOADSREC

command. The S-Records must be enclosed by quotation marks:

SOFTLOADSREC "<S-RECORD>"

6. Send the

SOFTLOADCOMMIT

command.

7. During the loading process, SOFTLOADSTATUSA logs report the load status. Wait for the

SOFTLOADSTATUSA to indicate loading is

COMPLETE

.

8. Send the new auth-code for the receiver with the following special case of the AUTH command:

AUTH ADD_DOWNLOAD

<auth-code>

9. Reset the receiver by entering

RESET

,

FRESET

or power cycling.

10. Once the receiver resets, the new version of firmware is active.

 The SoftLoad process can be canceled safely at any time during the process using the

RESET

command.

AG-Star User Manual Rev 4 40

NovAtel Firmware and Software Chapter 5

5.4.1

Working with S-Records

• Records beginning with S0, S5 and S7 should be passed to the receiver directly using the

SOFTLOADSREC command. These records contain meta data about the firmware image.

• Records beginning with S3 form the actual firmware image and can be converted to SOFTLOADDATA binary commands. Aside from the header, each pair of characters forms the ASCII representation of binary byte. The format is as follows:

S3 LL AAAAAAAA DDDDDDDD...DDDDDDDD

CC

Check Sum. One's compliment of all other bytes

Little Endian Data. These bytes are copied into the "data" field of the

SOFTLOADDATA command

4 - Byte Address. Set this as the value of "offset" in the SOFTLOADDATA command

Length. This is the hexadecimal number of character pairs to follow in the record. This value minus 4 bytes for the address and 1 byte for the check sum is copied into the "data length" field of the

SOFTLOADDATA command

Header

• Multiple S3 records can be packaged into a single

SOFTLOADDATA

command as long as the data from one S3 record follows immediately after the previous record, up to a maximum of 4096 bytes of data. That is, the address must equal the previous address plus the previous data length. The "offset" field remains the address of the first S3 record and the "data" and "data length" are updated to include the new data.

• The hex file data may contain many gaps and jumps. For example, in most NovAtel hex files data for address 0x000_00000 is stored near the very end of the file.

5.5

Upgrading Using the AUTH Command

The

AUTH

command authorizes the enabling (unlocking) of model features. The

AUTH

command is used to upgrade a new receiver model, available with the same firmware version as the current model. This command only functions with a valid auth-code assigned by NovAtel Customer Support .

The upgrade can be performed directly through the NovAtel Connect command line or from any other communications program.

 Refer to Section 5.3.1.1, Types of Firmware Files on page 37 for details on updating versus

upgrading.

5.5.1

Upgrade Procedure

1. Power up the receiver and establish communications.

2. Issue the

LOG VERSION

command to verify the current model, firmware version and serial number

(refer to Section 5.2, Authorization Code on page 36 for instructions on obtaining).

AG-Star User Manual Rev 4 41

NovAtel Firmware and Software Chapter 5

3. Issue the

AUTH

command, followed by the auth-code and model type (refer to Section 5.2,

Authorization Code on page 36 for details on obtaining any auth-code). The syntax is as follows:

auth <your auth-code here> where auth is a command that enables model upgrades and auth-code is the upgrade authorization code, expressed as follows:

XXXXXX,XXXXXX,XXXXXX,XXXXXX,XXXXXX,MODEL,EXPDATE where:

1. Each X character is a case-insensitive ASCII character.

2. The MODEL string is a maximum of 15 characters long and represents the model enabled by the authcode.

3. The EXPDATE string is the auth-code’s expiry date, in YYMMDD format

Example: auth 7WBMBK,887CB6,K5J3FH,5DF5P2,42PW8G,D1SB0GTT0,121211

When the

AUTH

command is executed, the receiver reboots. Issuing the

LOG VERSION

command confirms the new upgrade model type and firmware version number.

If communicating using NovAtel Connect, the communication path must be closed and reopened using the

Device menu.

AG-Star Communications/Power Cable (01018256)

The AG-Star cable that accompanies the AG-Star Development Kit, see Figure 28, AG-Star Communication/

Power Cable, provides a means of supplying power from a battery while operating in the field. The exposed

wires (red for positive and black for negative) can then be connected to a vehicular power circuit (or equivalent) protected by a 5A fast blow fuse (user supplied). The cable also has two DB-9 connectors. One can accommodate a computer serial (RS-232) communication port and the other can connect to a modem or radio transmitter to propagate differential corrections (refer to your user-supplied modem or radio transmitter user guide for more information on its connectors).

 Bluetooth wireless technology uses the COM2 port. When Bluetooth wireless technology is enabled, COM2 is not available on the AG-Star connector or the cable.

In addition, there are a number of bare wires where the outer insulation is cut away but the wires beneath are

intact. See Table 7, AG-Star Communication/Power Cable Pinouts on page 48 for their pinouts. For more

information on mating connectors and part numbers, see Table 8, AG-Star Mating Connectors on page 49.

This cable is RoHS compliant.

Description

The arguments for each of these commands are described in the following sections.

For a complete listing and description of the other commands that the AG-Star, an OEMStar-based receiver, is capable of processing, refer to the OEMStar Firmware Reference Manual .

B.1 Syntax Conventions

The following rules apply when entering commands, at the command prompt, from a keyboard.

1. Courier font is used to illustrate program output or user input.

2. References to other commands, logs or any of their fields are shown in italics.

3. The commands are not case sensitive. For example, you could type either RESET or reset.

4. Except where noted, either a space or a comma can separate commands and their required entries. For example, you could type either fix position 51.11358042 -114.04358013 1059.4105 or fix position 51.11358042, -114.04358013, 1059.4105.

5. At the end of a command, a carriage return is required. For example, press <Enter> or <Return> on your keyboard.

6. Responses are provided to indicate whether or not an entered command was accepted. The format of the response depends on the format of the command. Refer to the OEMStar Firmware Reference Manual for more information.

7. Optional parameters are indicated by square brackets ( [ ] ). For commands that contain optional parameters, the value used if the optional parameter is not specified is given in the syntax table for the command.

8. Data format definitions, as specified in the “Format” field, are detailed in the OEMStar Firmware

Reference Manual . Note that all binary data is little-endian byte-ordered.

AG-Star User Manual Rev 4 50

B.2 COM Configure COM Port

This command permits you to configure the receiver’s asynchronous serial port communications drivers.

The current COM port configuration can be reset to its default state at any time by sending it two hardware break signals of 250 milliseconds each, spaced by fifteen hundred milliseconds (1.5 seconds) with a pause of at least 250 milliseconds following the second break. This will:

• Stop the logging of data on the current port (see UNLOGALL command in the OEMStar Firmware

Reference Manual ).

• Clear the transmit and receive buffers on the current port.

• Return the current port to its default settings (see Factory Defaults section in the OEMStar Firmware

Reference Manual ).

• Set the interface mode to NovAtel for both input and output (see INTERFACEMODE command in the

OEMStar Firmware Reference Manual ).

 Baud rates higher than 115,200 bps are not supported by standard computer hardware. Special hardware may be required for higher rates, including 230400 bps, 460800 bps and 921600 bps.

Also, some computers have trouble with baud rates beyond 57600 bps.

Message ID: 4

Abbreviated ASCII Syntax:

COM [port] bps [parity[databits[stopbits[handshake[echo[break]]]]]]

Factory Default:

COM COM1 9600 N 8 1 N OFF ON

COM COM2 9600 N 8 1 N OFF ON

 On AG-Star receivers with Bluetooth wireless technology, the default settings for COM2 are: com2 115200 n 8 1 cts off off

Changing the COM2 serial port settings could interfere with the ability to communicate using

Bluetooth wireless technology.

ASCII Example:

COM COM1,57600,N,8,1,N,OFF,ON

Use the COM command before using the INTERFACEMODE command on each port.

 Watch for situations where the COM ports of two receivers are connected together and the baud rates do not match. Data transmitted through a port operating at a slower baud rate may be misinterpreted as break signals by the receiving port if it is operating at a higher baud rate.

This is because data transmitted at the lower baud rate is stretched relative to the higher baud rate. In this case, configure the receiving port to have break detection disabled using the COM command.

B.4 LOG Request Logs from the Receiver

Many different types of data can be logged using several different methods of triggering the log events. Every log element can be directed to any combination of the two COM ports. The ONTIME trigger option requires the addition of the period parameter. See the OEMStar Firmware Reference Manual for further information and a complete list of data log structures. The LOG command tables in this section show the ASCII command format.

The optional parameter [hold] prevents a log from being removed when the UNLOGALL command, with its defaults, is issued. To remove a log that was invoked using the [hold] parameter requires the specific use of the UNLOG command. To remove all logs that have the [hold] parameter, use the UNLOGALL command with the held field set to 1.

The [port] parameter is optional. If [port] is not specified, [port] is defaulted to the port that the command was received on.

 1. The OEMStar family of receivers can handle 30 logs at a time. If you attempt to log more than 30 logs at a time, the receiver responds with an Insufficient Resources error.

2. Maximum flexibility for logging data is provided to the user by these logs. The user is cautioned, however, to recognize that each log requested requires additional CPU time and memory buffer space. Too many logs may result in lost data and degraded CPU performance. Receiver overload can be monitored using the idle-time field and buffer overload bits of the Receiver Status in any log header.

3. Polled log types do not allow fractional offsets or ONTIME rates faster than 1Hz.

4. Use the ONNEW trigger with the MARKTIME or MARKPOS logs.

5. Only the MARKPOS or MARKTIME logs, and ‘polled’ log types are generated ‘on the fly’ at the exact time of the mark. Synchronous and asynchronous logs output the most recently available data.

6. If you do use the ONTIME trigger with asynchronous logs, the time stamp in the log does not necessarily represent the time the data was generated, but rather the time when the log is being transmitted.

The above example shows BESTPOS logging to COM port 1 at 7 second intervals and offset by 0.5 seconds

(output at 0.5, 7.5, 14.5 seconds and so on). The [hold] parameter is set so that logging is not disrupted by the UNLOGALL command.

To send a log only one time, the trigger option can be ignored.

Refer to the Command Formats section of the OEMStar Firmware Reference Manual for additional examples.

 1. In NovAtel Connect there are two ways to initiate data logging to the receiver's serial ports.

You can either enter the LOG command in the Console window, or use the interface provided in the Logging Control window. Ensure the Power Settings on your computer are not set to go into Hibernate or Standby modes. Data is lost if one of these modes occurs during a logging session.

2. Only the ASCII/Abbreviated ASCII log table is included in this manual. Refer to the LOG command in the OEMStar Firmware Reference Manual for binary log details.

Appendix C Logs

C.1 Position Logs

C.1.1

NMEA Logs

The NMEA logs (receiver outputs) supported by the AG-Star are summarized in the OEMStar Firmware

Reference Manual . The available logs include:

• GPGGA, which outputs a log of position system fix data and undulation. There are variants of

GPGGA, specifically:

GPGGALONG, which has both greater precision and the undulation field

• GPVTG, which outputs track made good and ground speed

The steps for configuring the receiver output, through the command line are:

1. Configure the communication port using the COM command, described in Section B.2, COM Configure

COM Port on page 51. To set COM port 2 as follows:

Bit Rate

Parity

Data Bits

Stop Bits

Handshaking

Echo

Break

8

1

9600 none

None

Off

On enter the following string: com com2 9600 n 8 1 n off on

2. Select and configure the NMEA string that you want to output. For example, to log gpgga (position system fix data and undulation) at 2 Hz, enter the following string: log gpgga ontime 0.5

You can configure the log to output at various frequencies, as described in Section B.4, LOG Request Logs

from the Receiver on page 54.

The above command line operations can also be carried out through NovAtel Connect. Information about configuring the communication port can be found in the NovAtel Connect online help. The procedure for adding a NMEA log through NovAtel Connect is summarized as follows:

1. In the Logging control window, click Logging to one or more of the receiver's serial ports. The Add Log window displays.

2. Beside Select list, select Complete List or NMEA List.

3. Beside Log to file, select the NMEA log you want to add.

4. Select the port.

5. Configure the remaining fields then click Add.

AG-Star User Manual Rev 4 61

C.1.2

NovAtel Position Logs

In addition to NMEA logs, NovAtel supports a range of non-NMEA position logs, described in the OEMStar

Firmware Reference Manual , including:

• BESTPOS: This log contains the best available position computed by the receiver, for example: log bestposa ontime 0.5

• BESTXYZ: This log contains the receiver’s best available position and velocity in ECEF coordinates, for example: log bestxyza ontime 1

C.2 Other Logs

The AG-Star firmware generates the logs in Table 16, AG-Star Logs in Alphabetical Order, in addition to

those of the OEMStar family log set. Refer to the OEMStar Firmware Reference Manual , which also contains procedures and explanations related to data logging.
