If you're having difficulty displaying AIS on your chart plotter, please follow the instructions below.
- Some old Chart plotters do not support AIS so you'll need to confirm compatibility by checking the manual for reference to AIS and/or VDM.
- Check the receiving port can be configured to 38400 baud on the chart plotter.
- Make sure it's connected correctly by simply connecting the NMEA0183 Transmit wires on the B400(Blue/White is TX B - , White/Blue is TX A +) to the corresponding NMEA0183 Receive wires on your compatible Chart plotter device. You'll need to connect the positive wires together and the negative wires together. For example:
- TX A to RX A
- TX B to RX B
The user manual details which cables do what, but for your reference, please see below for a table explaining the connections on the B400.
