6.17.1 How to enable the ignition function
The ignition function can be used to turn on/off the Communication Unit by means of
an external signal. The external signal that triggers the ignition function is positive DC
voltage, however the switch at the back of the Communication Unit must be turned on.
The ignition function uses pin 8.
Note: When this function is enabled, the system cannot be turned on unless an igni-
tion signal is received.
