CRITICAL DATA MODULE / DIGITAL
(part # 1096-0001 / Handlebar Mount)
NOTE: Please read these instructions completely before beginning installation.
Green LED display monitors Speed, RPM, Neutral Safety, Low Oil Pressure, Low Voltage, Engine Indicator,
Turn Signals & High Beam.
POWER
Connect the red wire from the main harness to accessory power from the ignition switch. In addition to powering the display system, this is also where
the low voltage detection circuit monitors the electrical system voltage. A good quality, solid state ignition switch should be used. The contacts on a
mechanical “bar” switch can bounce due to vibration causing the system to momentarily loose power and reboot. Never connect this to a battery charger without a battery. It needs to have a 12 volt battery connected to it. Battery chargers have an unregulated voltage output that will cause the system
to not operate properly.
GROUND
The black wire is the main ground connection for the display. This should be connected directly to the negative cable on the battery. Using a tank or
frame ground may result in a weak or intermittent ground connection. A poor ground connection can cause improper, inaccurate or erratic operation.
NEUTRAL, TURN & HIGH BEAM INDICATORS
The right turn, left turn and high beam indicators are activated by 12 volts at their respective wires. The right turn signal wire is green, the left turn signal wire is orange, and the high beam wire is purple. These can be connected to the same wires that the indicator lights are connected to. The display system wire colors may not match the wire colors in your electrical harness. The neutral indicator is activated when the blue wire is grounded.
Connect the wire to the neutral switch or to the negative side of the neutral indicator light. When the
Indicator is activated; an N will be lit up on the display to the right of the speedometer.
TRIP RESET & FUNCTION SWITCH
The push button switch is found on the rear of the display. To reset the trip
mileage press and hold the switch in. Pressing the switch while turning the power
on will enter the setup menus.
SPEEDOMETER
The speed input connector plugs into the speed sensor to determine how fast you are traveling. For transmissions having the built-in electric sensor, a
three-wire harness adapter connects the transmission speed sensor to the speedometer. This speedometer is fully adjustable and calibration is
discussed below.
SPEEDOMETER CALIBRATION
The speedometer calibration is done using the function (trip) switch. The speedometer can be calibrated two different ways. The first method is to
place the unit in auto-cal mode and drive exactly one mile (one km for metric). The second method is to place the unit in adjust mode and the speed
reading can be moved up or down while driving. The speedometer will provide a reading before it is calibrated, but it may not be accurate. If the
speedometer will only show 00, then it is probably not getting a speed signal. Check all of the wiring and mechanical connections carefully. If you are
using a stock electric transmission sensor, remove it and check for metal filings on the magnetic end. If you are using a cable-driven sensor, make
sure the cable and sensor are turning. If you are using a gear-tooth or bold-head sensor, check the spacing to the steel target (these sensors will not
read aluminum or stainless steel targets).
METHOD 1, AUTOCAL
Make sure the key is off so the module is not powered. Press and hold the function switch. Turn the key on. With the switch still held, start the bike. The
display will show “DISPLAY” “..”. Release the function switch. The display will switch between “AUTO” (auto cal), “ADJ” (adjust), “CYL”, “SET”, “BAR”,
and “VOLT”. The odometer will show “SELECT”. When “AUTO” is displayed press the function switch. This will place the unit in auto calibration mode.
Release the function switch. The odometer will show all zeroes. Drive exactly one mile (or 1 km). The odometer value will be calculated and stored.
The module will now reboot in normal mode with the new speed calibration.
Press and release the function switch. The calibration value will be calculated and stored.

METHOD 2, ADJUST SPEED
Make sure the key is off so the gauge is not powered. Press and hold the function switch.
Turn the key on. With the switch still held, start the bike. The display will show “DISPLAY” “..”. Release the function switch. The display will switch
between “AUTO” (auto cal), “ADJ” (adjust), “CYL”, “SET”, “BAR”, and “VOLT”. The odometer will show “SELECT”. When “ADJ” is displayed press the
function switch. This will place the unit in calibration adjustment mode. Release the function switch. The display shows the speed and the odometer
will show “ADJUST.” Drive at a known speed. Following another vehicle that is moving at a constant, known speed for this. Press the function switch.
The indicated speed will begin increasing until the function switch is released. The next time the function switch is pressed, the indicated speed will begin
decreasing. When the indicated speedometer reading is correct, release the function switch. The new calibration will be saved if no adjustments are made
for 7-10 seconds.
SPEED OUTPUT FOR TURN SIGNAL CANCEL MODULES
The display system also has a speed output signal for cycles equipped with an automatic turn signal cancel module or cruise control module. The white
wire from the controller harness should be connected to the module where the wire from the original analog speedometer was connected. The wire from
the original speedometer is typically a white/green wire.
TACHOMETER
The tachometer is enabled by connecting the yellow wire from the main harness to the negative side of the coil or to an ignition module tach output. The
tachometer is adjustable for 1-15 cylinder settings. The single cylinder setting is used for single-fire ignition systems without a buffered tach output.
The following instructions are used to set the tachometer output:
Make sure the key is off so the module is not powered. Press and hold the function switch. Turn the key on so the module is powered. The display will
show “DISPLAY” “..”. Release the function switch. The display will switch between “AUTO” (auto cal), “ADJ” (adjust), “CYL”, “SET”, “BAR”, and “VOLT”.
The odometer will show “SELECT”. When “CYL” is displayed press the function switch. This will place the unit in tach calibration mode. Release the function switch. This display will switch between “1 C”, “2 C”,…”15 C.” When the desired setting is displayed press the function switch. The display will show
“DONE.” Release the function switch. The system will now reboot normally with the new setting.
TACHOMETER SHIFT INDICATOR / RED LINE
A single bar will light up to indicate a shift point or red line. The rpm where the bar lights up is user selectable and can be turned off completely if
desired. The bar is factory set to approximately 6000 rpm.
The following instructions are used to set the tachometer warning bar:
Make sure the key is off so the module is not powered. Press and hold the function switch. Turn the key on so the module is powered. The display will
show “DISPLAY” “..”. Release the function switch. The display will switch between “AUTO” (auto cal), “ADJ” (adjust), “CYL”, “SET”, “BAR”, and “VOLT”.
The odometer will show “SELECT”. When “SET” is displayed press the function switch. This will place the module in the shift/red line set mode.
Release the function switch. The bar display will star at 2 and begin moving up. After it reaches the top it will go out and then start back at 2.
When the desired rpm setting is displayed press the function switch. To disable this feature, press the function switch while the bar is not displayed. The
display will show “DONE” once the new setting is stored. Release the function switch. The system will now reboot normally with the new setting.
TACHOMETER BAR RANGE
The tachometer bar can be set to 0-5000, 0-8000, or 0-16,000 rpm full scale range. The bar is factory set to 8000 rpm full scale.
The following instructions are used to set the tachometer bar range:
Make sure the key is off so the module is not powered;Press and hold the function switch. Turn the key on so the module is powered. The display will
show “DISPLAY” “..”. Release the function switch. The display will switch between “AUTO” (auto cal), “ADJ” (adjust), “CYL”, “SET”, “BAR”, and
“VOLT”. The odometer will show “SELECT”. When “BAR” is displayed press the function switch. This will place the unit in the bar range set mode.
Release the function switch. The bar display will show the 5000 scale, the 8000 scale, then the 16000 scale. When the desired RPM bar scale is displayed, press the function switch. The display will show “DONE” once the new setting is stored. Release the function switch. The system will now start
up normally with the new setting.
LOW OIL PRESSURE, LOW VOLTAGE, AND ENGINE INDICATORS
The low oil pressure warning light is activated when the gray wire is grounded. Connect this wire to the oil pressure switch on the negative side of the oil
warning light. The low voltage warning light is activated when the voltage at the red “power” wire drops below 11.5 volts & there is a tachometer signal
or below 10.5 volts when there is not tachometer signal. The “ENGINE” indicator is activated when the white/red wire is grounded. Connect this to the
ECM or ignition module black/yellow wire or leave it open on earlier systems.
NIGHT OPERATION (reduced display intensity)
Your display module has a dimming feature that reduces the display intensity during nigh time operation. Normally the panel is at maximum brightness
for optimum daytime viewing. When the brown wire has 12 volts the display intensity will be reduced. A toggle or on/off push button switch can be connected to this wire if this feature is to be functional. To have the display panel at full brightness all the time, leave the brown wire disconnected.

MOUNTING the CDM
The optional mounting bracket must be purchased separately for your application.
To mount the module under the bar:
Remove the rear plate by unscrewing the four screws. Remove the rubber cap from the switch. Flip the rear plate over so the mounting tab is on the top.
The hole for the switch should stay on the same side. Place the switch through the hole and replace the rubber cap. Reattach the rear plate using the
four screws. Place bar mount bracket on the handle bars so that the recessed screw holes are on the top. Using the long screws, secure the module to
the bottom side of the bar mount bracket.
WIRING
In order to ensure that there are no problems with voltage drops causing the system to shut down, a heavy duty solid state ignition switch is recommended. Also, the black wire should be connected directly to the negative battery terminal to avoid erratic operation due to a poor ground connection.
A complete description of the hookup for each wire is discussed in the previous sections of the installation manual. The typical color code for the stock
wiring harness is provided to help in wiring. Not all wires will be found in all bikes. Some bikes may have the same color wire used in more than one
place. The wire color code for the main display system harness is as follows:
