Wiring Connection
• Keep electrical and transducer cables away
from alternator or other noise generating
electrical cables. Avoid connecting the
instrument to power circuits that share
loads with ignition, alternators, inverters and
radio transmitters. Electrical power supply
connections should always be as short as
possible.
• Connect the red wire to the positive supply
via a 1 amp fuse or a 1 amp circuit breaker.
Connect the black wire to the electrical
ground. A 1 amp fuse will provide protection
for up to five 100 series instruments.
Multiple Instruments
The NAVMAN D100 may be used as an individual
instrument or connected with a number of other
100 series instruments to the 100 series
repeater or to other instruments accepting
NMEA 0183 data.

• Connect the RCA phono connector to the
depth transducer cable connector. Do not
cut or shorten the depth transducer cable.
Extension cables are available if the
transducer cable is too short.
• If you are not using a repeater or you do
not intend to provide NMEA data to another
instrument then insulate the bare wire end
of the blue cable.
