NMeA 0183 connection exceptions
The orange (Accessory-ON) wire is used when
connecting the antenna to a Garmin chartplotter,
or other NMEA 0183 device that has a defined
accessory signal wire. If you are connecting the
antenna to a device that does not have an accessory
signal wire, the orange wire from the antenna should
be connected to ground.
If you are connecting the antenna to a device that
does not have an accessory signal wire (Accessory-
ON), connect the antenna power wire to the ignition
or install an in-line switch. The antenna will drain the
battery of the boat if it is not switched.
• If your NMEA 0183-compliant device has
only one receiving wire (Rx), connect it to the
gray wire (Tx/A) from the antenna, and leave
the white/red wire (Tx/B) from the antenna
unconnected.
• If your NMEA 0183-compliant device has only
one transmitting wire (Tx), connect it to the white
wire (Rx/A) from the antenna, and connect the
white/orange wire (Rx/B) from the antenna to
ground.
Limiting the Antenna update Rate
By default, the antenna outputs position data
updates 10 times per second using serial
communications rate of 38400 bps. By installing the
included resistor cable the antenna can be limited to
output position updates once per second using serial
communications rate of 4800 bps.
1
Mount the antenna according to these
instructions.
2
If necessary, cut the cable to the appropriate
length for the installation.
3
Solder the included rate-change cable in-line with
the orange Accessory-ON wire.
4
Use heat-shrink tubing around the soldered
connections.
5
If you have not connected the antenna already,
connect the power and data cables.

Important Safety and Product
Information
Your GPS unit may use an internal, non-user-
replaceable battery for various purposes, such as the
real-time clock.
Do not remove or attempt to remove the non-user-
replaceable battery.
When disposing of the unit, take it to a professional
service, such as a waste electronics treatment
facility, to have the battery removed and recycled.
