Garmin GPSMAP 8X10, Installation Instructions Manual

Page: 5 / 8

• You must use 28 AWG, shielded, twisted-pair wiring for
extended runs of wire. Solder all connections and seal them
with heat-shrink tubing.
• Do not connect the NMEA 0183 data wires from this device
to power ground.
• The power cable from the chartplotter and the NMEA 0183
devices must be connected to a common power ground.
• The internal NMEA 0183 ports and communication protocols
are configured on the chartplotter. See the NMEA 0183
section of the chartplotter owner's manual for more
information.
• See the chartplotter owner's manual for a list of the approved
NMEA 0183 sentences that the chartplotter supports.
NMEA 0183 Device Connections
This diagram illustrates two-way connections for both sending
and receiving data. You can also use this diagram for one-way
communication. To receive information from a NMEA 0183
device, refer to items , , , , and when connecting the
Garmin device. To transmit information to a NMEA 0183 device,
refer to items , , , , and when connecting the Garmin
device.

Tx/B (Out -) Pink Rx/B (In -)
If the NMEA 0183 device has only one input (receive, Rx) wire
(no A, B, +, or -), you must leave the pink wire unconnected.
If the NMEA 0183 device has only one output (transmit, Tx) wire
(no A, B, +, or -), you must connect the white/orange wire to
ground.
Lamp or Horn Connections
The device can be used with a lamp, a horn, or both, to sound or
flash an alert when the chartplotter displays a message. This is
optional, and the alarm wire is not necessary for the device to
function normally. When connecting the device to a lamp or
horn, observe these considerations.
• The alarm circuit switches to a low-voltage state when the
alarm sounds.
• The maximum current is 100 mA, and a relay is needed to
limit the current from the chartplotter to 100 mA.
• To toggle visual and audible alerts manually, you can install
single-pole, single-throw switches.

NMEA 0183 with Audio Cable Pinout
The optional NMEA 0183 with audio cable (010-12852-00)
includes bare wires and an RCA connector for an audio out
connection to a stereo, including Fusion ® stereos. This cable can
be purchased from garmin.com or your local Garmin dealer.
You can connect the RCA connector to the AUX input of the
stereo. Audio received from the HDMI
®
input to the chartplotter is
output to the stereo.
The NMEA 0183 with audio cable provides one differential
NMEA 0183 input and output port.
