Ignition input switch jumper (CN8)
This jumper determines if the Vehicle Mounted Computer can be acti-
vated by linkage to a vehicle ignition switch.
The default setting reserves the jumper open. To enable the power-on
function via the vehicle ignition switch, it is necessary to change the
power fail function setting from BIOS (
See Appendix B.2
) and connect
the signal pin of the power cord supplied with the TREK (
See Section
2.2.1
) to the car engine circuit. This function can be disabled by either
closing the jumper or connecting the signal pin of the power cord with the
anode of car battery. The setting is shown below:
Table 4.12: Ignition input switch jumper (CN8)

Ignition turn-on disable
Note:
See Chapter 2, Section 2.2.1 for a diagram of
the ignition signal wire on the power cord.
