Power Wiring
Power the ADL2 via a separate switch and a 5 Amp fuse. The separate
switch is recommended so that the computer can communicate with the ADL2
without needing to turn the rest of the vehicle power on.
Ground Wiring
Ground the ADL2 to a good ground. The ground should have a direct
connection to the vehicle battery.
USB Wiring
See Appendix J: USB Wiring for USB wiring details.
CAN Bus Wiring
Refer to Appendix H: CAN Wiring for details.
Sensor Wiring
MoTeC can supply wiring details for all sensors.
External Buttons
A number of external buttons are required for various functions of the ADL2.
Typically these buttons are used for:
• Display
Mode
• Display Next Line (and optionally Previous Line)
• Alarm
Acknowledge
• Lap Number Reset
• Fuel Remaining Reset
These buttons are normally wired to the ADL2 Switch Input pins, but may also
be wired to the Digital or Analog Inputs, if the Switch Inputs are occupied.
The buttons should be wired between an ADL2 input and ADL2 0V pins.
Note that if wired to an Analog Voltage input an external pull-up resistor must
be connected between the input pin and the 5V sensor supply.
