Cigarette Lighter Power Adapter
To use external DC power, plug the power cable's cigarette lighter
adapter into a cigarette lighter receptacle. Next, pull aside the rubber
cover on the bottom of the unit and insert the other connector as shown
in the following image. A small clip on the connector should hold the
connector in place.
Attach external power cable to the iFINDER.
WARNING:
Do not remove the cigarette lighter adapter and splice
the exposed wires directly to a 12-volt power system. The
cigarette lighter adapter contains in the plug a protec-
tive fuse and a voltage regulator to convert 12 volts
down to about 3 volts. Without this regulator, connecting
your unit to a 12-volt power source will destroy the unit.
This damage will not be covered by your warranty.
The iFINDER can use two other optional external cables to supply a
NMEA/serial data connection or a combination of power and data. These
cables are discussed in the following segment on NMEA connections.
NMEA Cable Connections
NMEA is a standard communications format for marine electronic
equipment. For example, an autopilot can connect to the NMEA interface
on this unit and receive positioning information. The unit can exchange
information with any device that transmits or receives NMEA 0183 data.
To exchange NMEA data, Lowrance offers an optional data only cable
and a power/data combo cable:
The PC-DI7 is a NMEA/serial communications cable. It has a standard
female DB-9 connector on one end to attach your unit to a computer's
serial communications port.
The PC-DI8 combines a cigarette lighter power adapter with a DB-9
plug for a NMEA/serial com port connection to a laptop computer or
