Connecting a “Silent” switch (optional)
A toggle switch can be connected to the AIS transponder to provide remote control of silent mode.
Connect the toggle switch between the White(+) and Blue(-) wires as shown below. Connection of an ex-
ternal switch to toggle silent mode is optional and not essential for normal operation of the product.

Connecting to NMEA0183 compatible equipment
The AIT2000 has two independent NMEA0183 data ports which are pre-configured at the following data
rates; Port 1 = 38400 baud and Port 2 = 4800 baud.
Each port consists of a two wire Input and a two wire Output, which are colour coded as shown in Table 1.
Connect the wires to the appropriate connections on your NMEA0183 compatible equipment. Please re-
fer to your equipment manual for more information and pay particular attention to any menu settings
that must be configured to configure and display AIS or other NMEA data.
The high speed NMEA Output port 1 is intended primarily to connect to a chart plotter, while the low
speed NMEA Input and Output of port 2 are intended to connect to other NMEA0183 devices.
