Garmin GPS 17 Installation Manual page 13

To wire the GPS 17 to a NMEA Device or PC
Connector:
1. Connect the White (Port 1 Data Out) wire from the
GPS 17's power/data cable to the DATA INPUT line
of the NMEA device or to pin 2 on a DB-9 (pin 3 on
DB-25).
2. Connect the Blue (Port 1 Data In) wire to the DATA
OUTPUT line of the NMEA device or pin 3 on the
DB-9 (pin 2 on DB-25).
3. Connect the Black (-) wire to the GROUND wire of
the NMEA device and/or pin 5 on the DB-9 (pin 7
on DB-25). If connecting to a PC, the Black (-) wire
must also be run to a ground.
If the Black wire is connected to the same ground
terminal as the NMEA device, no additional
connection is required, unless a separate data return
line is required by the NMEA device.
4. Connect the Red (+) wire from the power/data cable
to a 8–40 VDC power source.
GPS 17 Installation Guide
5. If the receiver is being wired to a circuit that is
already switched, (with the NMEA device for
example) connect the Yellow wire to the same place
as the Black wire. When the Black and Yellow wires
are combined, the GPS 17 will turn on/off when
power is applied/removed to the Red (+) wire.
If a remote power switch is being installed, refer to
Figure 6 on page 7. This will allow the GPS 17 to
remain connected to a power source but manually
powered on (pull down to less than 0.5 volts) and off
(open).
Some non-Garmin devices may have a separate data line
labeled RETURN, DATA GROUND, or DATA -. If one of
these lines exist, connect the Black wire from the power/
data cable to it.
You may output data to up to three NMEA devices. The
number of devices is determined by the total amount of
impedance from all devices.
