If you're having difficulty displaying AIS on your chartplotter, 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 NMEA 0183 transmit wires on the B900 Series (Brown is TX+, Blue is TX-) to the corresponding NMEA 0183 receive wires on your compatible chartplotter. You'll need to connect the positive wires together and the negative wires together. For example:
- TX+ to RX+
- TX- to RX -
The user manual details the function of each wire, but for your reference please see below a table explaining the connections on the B900 Series:
