3.3.2 Connecting to the ignition
The Communication Unit has an ignition function. When this function is used, the
Communication Unit switches on/off when you start/stop the engine of your vessel
(provided the power switch on the Communication Unit is on; on the 19” rack version
both power switches must be on).
Note: You must set up the ignition function in the Communication Unit. For details, see
the Operator’s Manual for your FELCOM251/FELCOM501.
To implement the ignition function, connect the appropriate pin in the I/O connector to
the ignition key switch:
• Active high (default): Connect pin 8 to "high" (12 to 24VDC (-10% to +30%)) when
the ignition is on.
For pinout, see section 5.8.
For information on the standby current when the ignition power is off, see the Opera-
tor’s Manual (OME-57050) for FELCOM251/FELCOM501.
