10.7.1 Power supply connections
The internal voltage regulator will allow the CPXX to operate normally over the
power supply voltage range from 10 to 32 Vdc. Connection between the CPXX
and the external power supply is accomplished by means of the supplied power
cable, which is approximately 1.5 meters long.
After connecting the cable to the power source, push the plug as far as it will go
into the three pin receptacle marked “PWR” on the rear of the cabinet and turn
the plug’s coupling ring clockwise until it makes a click.
10.7.2 Fuse
Warning! A fuse should always be installed to protect the unit.
Using a fuse which is not specified for your equipment can cause it to blow the
instant the CPXX is switched on or it will not protect the equipment as intended
– see fuse rating in section 10.12 Specifications.
10.7.3 NMEA0183 interface connections
NMEA0183 interface connections are made to the receptacle marked “NMEA1”
or “NMEA2” on the rear of the cabinet – turn the plug’s coupling ring clockwise
until it stops.
) The CPXX must be turned off while connecting/disconnecting the interface
cable.
10.7.4 PC up/download via NMEA connection
A PC can be connected via the NMEA port to enable exchange of waypoint and
route data. See 10.8 Optional connections.
