The MDC gets all its inputs from the engine sensors, tach signal, ignition switch and battery. All these inputs go into the 18-pin (INPUT) connector from the engine harness. Always make sure the MDC has a good ground and 12 volts before troubleshooting.

Speed information is fed to the MDC through the two inputs labeled Primary and Secondary. This is accomplished with the speed pickups at the back of the boat and the tubing running to the primary and secondary inputs.

The 5-pin connector is considered the output connector because it delivers all the power and information for the instruments to operate. Never attach anything other than instruments to the output harness.

• Shifting technology (from air core to digital)

• Increased use of multiplexed communications

• Pitot to paddle wheel

• Increased feature content

• Increased value

The Marine Data Concentrator

The MDC receives digital and analog data from the sensors in the boat and converts them to digital messages for the analog display instruments. This module is limited to the digital instruments and does not support additional accessories.

The Marine Data Concentrator (MDC) is usually mounted on the interior surface of the pod as close to the rear of the instrument panel as possible. Use 4-6 fasteners to attach the MDC through the mounting holes.

Select the best fastener for the mounting environment.

Self-tapping screws or small bolts may be best.

These are pressure hose connectors for one or two pitot lines marked

“primary” and “secondary.”

This is the input socket for the

Packard 18-pin

input connector.

This is the output socket for the Packard

5- pin output connector port. Display data exits here and passes through the Universal Bridge Harness to the instruments.


Instruments

All instruments contain a processor that has its identity defining whether it is a speed, tach, fuel or so on.

Lighting is achieved by using LEDs. LED draws only

20 ma and is very bright. It is also available in several colors.

Stepper motors replace the air core for pointer movement. The stepper motor has 30 times more torque than the air core. With that torque you can achieve accuracy of 1/3 of a degree.

Packard 5-pin MDC Connector

and Instrument Connectors

It is very easy to cause failures to any system by not using proper methods when probing connectors.

Whenever possible, avoid sticking probes, clips, and anything larger than the terminal into a connectors mating side. This will damage the terminal by either stretching it or forcing it out of the connector.

Back probing with a “T” pin will help eliminate any damage to the connector.

It is very easy to damage the terminals if testing is done on the front side of the connector. Damaging the terminal in this fashion will cause intermittent or failure of the MDC or instruments.

L K J H G

Using “T” pins in the back of the connector will help prevent any damage to the connector or terminals.


The Multi-Marine Data Concentrator

The MMDC gets all its inputs from the engine sensors, paddle wheel, ignition switch and battery. All these inputs go into the 24 pin (INPUT) connector from the engine harness. Always make sure the MMDC has a good ground and 12 volts before troubleshooting.

LCD Options

• Plug-in play options: When an option is plugged in the data will appear on the LCD.

• Depth/Air temp: 400-foot depth; adjustable shallow alarm.

The hour meter is displaying boat hours and is stored in the MMDC. Replacing the MMDC will erase the hours.

The MMDC will only count when the RPM is above 300.

From this screen you can also change the LCD to metric.

This is done by holding down the LCD button for three seconds. When prompted, use the LCD button to select English or metric. After selection, wait three seconds and the display will return to normal operation.

The clock can be adjusted by holding down the LCD button when the clock is displayed. After three seconds the colon will stop flashing. After it stops flashing, adjust hours by pressing down and adjust minutes by pressing up. When complete, wait three seconds and the clock will return to normal operation.

MasterCraft LCD System

The MasterCraft LCD system has a clock, hour meter, digital tachometer and lake temperature standard. It also has a plug-and-play software, making it easy to add options such as depth finder, air temperature or GPS, using the same display.

Also, the LCD display has several alarms. The following messages will be displayed if an alarm occurs.

VOLT = volts below 11.5.

OIL = oil below 4 psi when rpm is below 1000 rpm or oil pressure is below 10 psi and above 1000 rpm.

TEMP = high temperature alarm from the engine

ECM.

TRAN = transmission alarm from the engine ECM.

All adjustments are done with the same LCD button.

You can toggle through the display and make changes to the clock, shallow alarm, select Met/Eng, activate the self test, and even auto calibrate using a GPS when installed.

Lake temperature is also standard on the LCD system. Lake temperature comes from the paddle wheel under the boat. If the sensor becomes open or shorted to the battery the temperature will read 32 o

F or it will not be displayed. If the sensor is shorted to ground, it will read 150 o

F.

MasterCraft Depth Option Operation

The MasterCraft module is an option that will work as a plug-and-play feature with the MasterCraft LCD system.

Just plug the connector into the MasterCraft dash harness and connect the power for the Lowrance depth unit.

After the connections have been made, the depth information will begin to display on the speed LCD.

The depth module will read up to 400 feet and has a shallow alarm.

The shallow alarm is adjusted by doing the following:

1. Depth displayed on the LCD.

2. Hold the LCD button down for three seconds or until current set point is flashing.

3. Adjust set point by pressing the LCD button up or down.

4. When adjusting is complete, do nothing for three seconds and the display will return to normal operation.

The MasterCraft LCD system comes with clock, hour meter, tachometer and lake temperature standard.


Note 2: Voltage will read 0 vdc when the switch is pressed down. Voltage will read 5-12 vdc when switch is open or button is not pressed.

MMDC-IN Harness Pin Detail

2004

Under normal conditions, the depth will indicate up to

400 feet. To change the alarm set point, press the LCD

Model button when in depth mode for three seconds or until the depth flash. At this point the shallow alarm set point is flashing. Use the LCD mode switch to change the setting up and down. When finished, wait three seconds and the display will go back to normal operation.

If “BAD” is displayed, the depth module has lost power on the red and black wire located on the depth module. If power is present the module has gone bad.

When “NRES” is displayed, it means the depth module did not transmit any depth information to the MMDC.

This will only happen when a depth module fails during operation.

The new LCD system all starts at the MMDC. If all the segments appear at start-up or during self test, the

LCD is probably good.

Controlling the LCD is done with the LCD momentary switch located on the dash. Momentary pressing up or down will toggle you through the LCD. If the toggle up does not work, look for the following problem:

The wire to pin 14 on the 24-pin connector is open (momentary ground on this pin makes the LCD toggle forward).

For toggle down failure the following may be the problem:

The wire to pin 17 on the 24-pin connector is open (momentary ground on this pin makes the LCD toggle backwards).


The hour meter is automatically incremented when the RPM is above 300 RPM. If it does not increment or fails to save the hours the following may be the reasons:

1. The battery wire located on pin 12 of the 24-pin connector was removed before ignition was removed

(pin 11 on the 24-pin).

2. Not receiving RPM signal from the engine on pin 6 of the 24-pin connector.

3. Ground on pin 24 of the 24 pin has come off.

6-pin connector to Depth/GPS.

After the clock is set it will keep correct time unless all power is removed. It will not save the correct time for the following reasons:

1. The battery wire located on pin 12 of the 24-pin connector was removed before ignition was removed

(pin 11 on the 24-pin).

2. Ground on pin 24 of the 24 pin has come off.

Under normal conditions, the Depth will indicate up to 400 feet. The LCD will flash the last known depth if the transducer fails to get a solid reading. It will also flash if the transducer fails or is not hooked up.

If “BAD” is displayed when one of the following problems have occurred.

1. The black or red wire powering the Lowrance unit is not attached.

2. The depth module has failed.

Lake temperature comes from the paddle wheel under the boat. At room 70 o

F the sensor will read about

10000 ohms.

1. If the sensor wire (pin 3 on the 24-pin connector) becomes open or shorted to the battery, the temperature will read 32 o

F or it will not be displayed on the LCD.

2. If the sensor is shorted to ground it will read 150 o

F.

When “NRES” is displayed, it means the depth module did not transmit any depth information to the MMDC.

This could happen under the following conditions:

1. Power or data to depth has come off or failed.

2. Unit failed during operation.

Troubleshooting

Both the Depth/GPS plug and play options are connected through the 10-pin connector. The connections are as follow:

1. 7 volt power pin E.

2. Ground pin F.

3. Digital high C.

4. Digital low H.

There is a 6-pin connector that connects the 10-pin

MMDC connector to the Depth/GPS module.

1. 7 volt power pin C.

2. Ground pin D.

3. Digital high B.

4. Digital low E.

Any one of those pins are not correct or missing the

Depth/GPS will not show on LCD.

The other half of the Depth module is the LSM-3 made by Lowrance. The Lowrance unit has its own power and ground wires. Without those power wires attached, the LCD will display “BAD.”

Measure the senders disconnected from the MMDC for resistance and attached with power on for voltage.

Resistance can be checked by disconnecting the

24-pin connector and measuring between the sender wire and ground.

Voltage can be measured by back probing the sensor wires.


DVM Readings

Note 1: Reading can be taken with an ohm meter on the brown for lake temp (pin 7) and yellow for the air temp (pine 13). All sensor wires are found on the 24-pin connector.

Note 2: All voltage readers are not exact; use +/-

The Multi-Marine Data Concentrator

CAN Version

The CAN MMDC is designed to use CAN data from the engine ECM. CAN is a much more reliable and faster than the old data from the ECM. Faster data lets us have more information to display to the users. Basically all the engine information is being broadcast on the CAN system.

Always ensure the MMDC has a good ground and 12 volts before troubleshooting.

The 10-pin connector is considered the output connector because it delivers all the power and information for the instruments to be operated. Never attach anything other than instruments to the output harness.

MasterCraft Cruise LCD

The MasterCraft Cruise LCD was designed to take advantage of the throttle-by-wire system offered by the engine upgrade. This is a basic cruise that will allow the user to select three different modes of control: RPM, speed or manual.

In all cases when the engine has control until the

LOCK icon is on solid. The LOCK will flash when the engine does not have control.

Another feature is PULL mode. The PULL mode lets the user have control of the throttle until the boat is up to speed. You must be below 7 mph and 1000 RPM to use this feature. After the engine has reached the speed, it will display DEC to let the user know it is adjusting to the set point.


Cruise Control Operation in OFF Mode

Please refer to the operators manual for more detailed information.

System Start-up. When the ignition is turned on the cruise control system starts in OFF mode. While the system is in OFF mode, the LCD will show the current time.

The MasterCraft Cruise LCD comes standard with the engine upgrade that includes throttle-by-wire.

RPM Set Point Adjustment. In order to adjust the

RPM Set Point in OFF mode, first move the RPM/SPEED mode selection switch to the RPM position. Then, using the +/- switch select the desired Set Point. The RPM icon will illuminate and the LCD will display the current

Set Point. Short presses of the +/- switch will increase or decrease the Set Point by 20 RPM. Holding the switch increases or decreases the Set Point by 100 RPM. The

RPM Set Point is limited to a minimum of 1200 RPM and a maximum of 5000 RPM.

The cruise LCD has a built-in clock that will be displayed with the cruise is off and the key is on. After the cruise has been turned on you have three possible MODES to select from: speed, RPM or manual. Speed and RPM set points can be adjusted without turning on the cruise. This is done by selecting RPM or Speed on the mode switch and then pressing the adjust switch up or down.

The RPM mode works by giving the engine ECM a request for the RPM set point. The engine will attempt to hold the RPM set point as long as the throttle has been opened past the set point. If the throttle is below or moved below the set point the cruise will not LOCK.

Pulling back on the throttle and turning off the cruise system are the only ways to disengage the cruise.

Speed Set Point Adjustment. In order to adjust the Speed Set Point in OFF mode, first move the RPM/

SPEED mode selection switch to the SPEED position.

Then, using the +/- switch select the desired Set Point.

The SPEED icon will illuminate and the LCD will display the current Set Point. Short presses of the +/- switch will increase or decrease the Set Point by 0.2 MPH. Holding the switch increases or decreases the Set Point by 1.0

MPH. The Speed Set Point is limited to a minimum of

10.0 MPH and a maximum of 50 MPH.

The Speed mode works by giving the engine ECM a request for a speed. As long as the throttle has been opened enough the engine will attempt to hold that speed. There is a lower limit of 10 mph and an upper of

50 mph. After the engine has taken over the control of the throttle a LOCK will appear solid on the display.

Turning ON RPM Cruise Control Mode. To turn ON the Cruise Control System in RPM Control mode, make sure that the RPM/SPEED mode selection switch is in the RPM position and that the current engine speed is at least 400 RPM less than the Set Point. Then press and hold the ON/OFF switch in the ON position for approximately one second. The LCD should now display the current engine speed, the RPM icon should be illuminated and the LOCK icon should be blinking. The system is now in RPM Control mode.

The Manual mode works like a car cruise. If the switch is in manual mode and the cruise is turned on the current RPM is what the engine tries to hold. As with all the modes you can increase or decrease that set point by pressing the increase-decrease button.

Turning ON Speed Cruise Control Mode. To turn on the Cruise Control System in Speed Control mode, make sure that the RPM/SPEED mode selection switch is in the SPEED position and that current vessel speed is at least 3.0 MPH less than the Set Point. Then press and hold the ON/OFF switch in the ON position for ap-


proximately one second. The LCD should now display the current vessel speed, the SPEED icon should be illuminated and the LOCK icon should be blinking. The system is now in Speed Control mode.

Turning ON Manual Cruise Control Mode. To turn on the Cruise Control System in Manual Control mode, make sure that the RPM/SPEED mode selection switch is in the MANUAL (center) position and that current engine speed is at least 1200 RPM. Then press and hold the ON/OFF switch in the ON position for approximately one second. The LCD should now display the current engine speed and the LOCK icon should be blinking.

The system is now in Manual Control mode.

Cruise Control Operation in RPM Control Mode

Using Normal RPM Control Mode. Normal RPM

Control mode starts with the cruise control system on but not engaged. This is indicated by a blinking LOCK icon. In order to engage the cruise system, accelerate the boat until the LOCK icon stays on. Now the engine will hold the engine speed to the RPM Set Point.

Disengaging the Cruise Control System. There are two ways to disengage the system: Pulling back the throttle and moving the ON/OFF switch to OFF.

• Pulling back the throttle will disengage the system at any time. The system remains on and can be engaged by accelerating the boat until the LOCK icon stays illuminated.

• Moving the ON/OFF switch to OFF will turn the cruise system off. It is best to disengage the system by pulling the throttle back before turning the system off.

Cruise Control Operation in Speed Control Mode

RPM Set Point Adjustment. The RPM Set Point can be adjusted using the +/- switch. The RPM icon will illuminate, the LOCK icon will disappear and the LCD will display the current Set Point. Short presses of the

+/- switch will increase or decrease the Set Point by 20

RPM. Holding the switch increases or decreases the Set

Point by 100 RPM. The RPM Set Point is limited to a minimum of 1200 RPM and a maximum of 5000 RPM.

Speed Set Point Adjustment. The Speed Set Point can be adjusted using the +/- switch. The SPEED icon will illuminate, the LOCK icon will disappear and the

LCD will display the current Set Point. Short presses of the +/- switch will increase or decrease the Set Point by

0.2 MPH. Holding the switch increases or decreases the

Set Point by 1.0 MPH. The Speed Set Point is limited to a minimum of 10.0 MPH and a maximum of 50.0 MPH.

Using Pull Up Mode. Pull Up mode allows the driver to control the throttle until the boat gets up to speed.

When the boat is up to speed, the cruise control system will take over and decelerate the boat to the Set Point.

To use Pull Up mode, slow the boat down so that the engine speed is less than 1000 RPM and the boat speed is less than 7.0 MPH. The LCD will indicate that Pull Up mode is active by displaying PULL.

Using Speed Control Mode. Speed Control Mode starts with the cruise control system on but not engaged.

This is indicated by a blinking LOCK icon. In order to engage the cruise system, accelerate the boat until the

LOCK icon stays on. Now the engine will hold the vessel speed to the Speed Set Point.

After the boat is up to speed, the engine will decelerate down to the Set Point. The LCD display will indicate this by displaying DEC.

After the boat has decelerated, the system returns to normal RPM Control mode operation.

Disengaging the Cruise Control System. There are two ways to disengage the system: Pulling back the throttle and moving the ON/OFF switch to OFF.

• Pulling back the throttle will disengage the system at any time. The system remains on and can be engaged by accelerating the boat until the LOCK icon stays illuminated.

• Moving the ON/OFF switch to OFF will turn the cruise system off. It is best to disengage the system by pulling the throttle back before turning the system off.


Cruise Control Operation in Manual Control Mode

Manual Set Point Adjustment. The Manual Set

Point can be adjusted using the +/- switch. The LOCK icon will disappear and the LCD will display the current

Set Point. Short presses of the +/- switch will increase or decrease the Set Point by 20 RPM. Holding the switch increases or decreases the Set Point by 100 RPM. The

Manual Set Point is limited to a minimum of 1200 RPM and a maximum of 5000 RPM.

Almost make sure the MMDC has a good ground and 12 volts before troubleshooting.

The 10-pin connector is considered the output connector because it delivers all the power and information for the instruments to operate. Never attach anything other than instruments to the output harness.

Push the MENU button once to return to the MENU

DISPLAY screen.

Setting Specific Dealer Information

TThe following steps should be followed to access the specific dealer information:

1. You will need to be able to access an additional file. It has been sent with this Service Advisory and is called vdigsetup.txt. It will open in Notepad on PCs equipped with Windows. If it appears in your e-mail as a Plain

Text Attachment with the information already showing in the message, you can block and copy directly from the message.

2. The lines DEALER_LABEL_1 through DEALER_

LABEL_8 are the editable lines (shown in the vdigsetup.txt file with the factory information in italics) in which the dealer information can be substituted instead.

Edit the data on these lines ONLY. Do NOT change

any other information. Note that dealerships can input up to 21 characters per line on each of those lines 1-8 for display on the VDIG screen.

3. Save the vidgsetup.txt file to a USB flash/jump drive.

Do NOT re-name the file. The file MUST be called vdigsetup.txt in order for the VDIG to recognize and accept the information. Experience has shown that

VDIG likes a dedicated USB flash/jump drive. Dual engine vdigsetup.txt information on the same USB flash/jump drive will confuse the VDIG; it will search and try to download other files that may also be on the

USB flash/jump drive.

4. Insert the flash/jump drive into the USB port in the arm rest on the boat.

5. Turn the ignition key ON.

6. On the VDIG, advance to the Set-up screen.

7. Select “Reset VDIG.”

8. On this screen, press Select again to re-set the

VDIG.

9. While the VDIG is re-setting, press both the UP and

DOWN buttons simultaneously.

10. The VDIG should now display the “Boot loader” screen.

11. Use the UP and Down to select “Upload VDIG Setup

File.”

12. The bottom of the screen should say, “Programming

xxx bytes.”

13. The VDIG will automatically re-set again.

14. Verify the data under Setup/Dealer Info.

15. Turn the ignition key off.

16. Remove the flash/jump drive.

After the first time, downloading the information will take only about one minute to complete. The same file (and only this file) can be used on any single or dual-engine 2009 VDIG boat.
