• If the NMEA 0183 device has only one input (receive, RX) wire (no A, B, +,
or -), you must leave the TXB wire unconnected.
• If the NMEA 0183 device has only one output (transmit, TX) wire (no A, B,
+, or -), you must connect the RXB wire to ground.
NMEA 0183 Device Connected with a Single Receive Wire
In this example, the NMEA 0183 device is receiving data from the chartplotter.

Orange Accessory on
Lamp and 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 1 A, and a relay is needed to limit the current from
the chartplotter to 1 A.
• To manually toggle visual and audible alerts, you can install single-pole,
single-throw switches.
