MoTeC SDL - Manual (Page 21)

MoTeC Installation 19
Power Wiring
Power the SDL via a separate switch and a 5 Amp fuse. The separate switch
is recommended so that the computer can communicate with the SDL without
needing to turn the rest of the vehicle power on.
Ground Wiring
Ground the SDL 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 SDL.
Typically these buttons are used for:
• Display Next Line
• Alarm
Acknowledge
• Lap Number Reset
• Fuel Used Reset (can also be done by holding the alarm acknowledge
button for 2 seconds)
These buttons are normally wired to the SDL Switch Input pins, but may also
be wired to the Digital or Analog Inputs, if the Switch Inputs are occupied.
Note that it is possible to configure the ADL to use the Alarm Acknowledge
button to reset the Lap Number and Fuel Remaining by holding it for a period
of time. This reduces the number of buttons required.
The buttons should be wired between an SDL input and SDL 0V pins.
