Step 5 - Connecting an external switch for Silent Mode operation A toggle switch can be connected to the AIS transceiver to provide Fig. 10 External switrcehmote control of silent mode. Connect the toggle switch between the light green and orange wires as shown in Figure 10. Connection of an external switch to toggle silent mode is optional and not essential for normal operation of the product. Warning: Do not connect a voltage source across the switch inputs, as this may damage the transceiver.

Each port consists of four colour-coded wires, as shown in the table (Step 4) and in the diagram in Figure 11. Connect the wires to the appropriate connections on your NMEA 0183 compatible equipment. Please refer to your equipment manual for more information. The AIS transceiver has a high speed bi-directional port, which operates at 38,400 baud and a low speed bi-directional port, which operates at 4,800 baud. The high speed port is intended primarily to connect to a chartplotter, while the low speed port is intended to connect to other NMEA 0183 devices. A multiplexing feature is provided, which means any messages received via the low speed port are automatically transmitted via the high speed port and viceversa. This is particularly useful when using a chartplotter having 20 | Installation | NAIS-400 User Manual
