Wiring
the GPS 16
I
If the GPS 16 is being connected
to a PC, a DB9 or DB25 serial
connector (normally female) will
be needed. Check with a PC or
electronics supplier for this item.
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.

Basic Wiring for the GPS 16 to a NMEA 0183
Device or PC Connector:
1. You may reference the following diagrams for the
wiring: Connect the WHITE (Port 1 Data Out) wire
from the GPS 16’s power/data cable to the DATA
INPUT line of the NMEA 0183 device or to pin 2 on
a DB9 (pin 3 on DB25). You may typically output
data to no more than three NMEA devices.
2. Connect the BLUE (Port 1 Data In) wire to the DATA
OUTPUT line of the NMEA 0183 device or pin 3 on
the DB9 (pin 2 on DB25).
3. Connect the BLACK (-) wire to the GROUND wire
of the NMEA device or pin 5 on the DB9 (pin 7
on DB25). If connecting to a PC, you must also run
a separate BLACK (-) wire to a power ground. If
the BLACK wire is connected to the same ground
terminal as the NMEA 0183 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 DC power source.
5. If a remote power switch is being installed, refer-
ence the following page for wiring a switch. This
will allow the GPS 16 to remain connected to a
power source, but manually powered on (pull down
to less than 0.5 volts) and off (open). Otherwise,
if the receiver is being wired to a circuit which is
already switched, (with the NMEA 0183 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 16 will turn
on when power is applied to the RED (+) and
BLACK (-) wires.
