0OWER SUPPLY CONNECTIONS
The internal voltage regulator will allow the GN30 MKII to operate nor-
mally over the power supply voltage range from 10 to 32 Vdc. Connec-
tion between the GN30 MKII and the external power supply is
accomplished by means of the supplied power cable, which is approxi-
mately 1.5 meters long.
After connecting the cable to the power source, push the plug as far as it
will go into the two pin receptacle marked ’PWR’ on the rear of the cabi-
net and turn the plug’s coupling ring clockwise until it makes a click.
The use of longer cable runs, while possible, always increases the likeli-
hood of increased interference and decreased performance. Care must be
taken when increasing the cable lengths to ensure that proper, adequate
and consistent shielding is maintained, that cable of adequate cross sec-
tion is used, and that all connections are properly made and protected
from the effects of the marine environment.
&USE
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 GN30 MKII has been switched on or it will not pro-
tect the equipment as intended.
.-%! INTERFACE CONNECTIONS
NMEA 0183 interface connections are made to the receptacle marked
’NMEA’ on the rear of the cabinet.
