CB2 Manual
Default NMEA Port Settings
The CB2 includes 2 bidirectional NMEA 0183 ports.
The baud rate for each port can be configured via the set-up application. Both ports can
be multiplexed to enable GPS data provided to one port to be combined with AIS data and
output on the other port.
Typically port 1 is connected to an MFD and configured for 38,400 baud rate, the baud rate
required for AIS data transfer. Port 2 is connected to a Heading sensor or other NMEA 0183
device and configured for 4,800 baud rate.
Details of the NMEA0183 sentences accepted and transmitted by each channel are to be
found in Section 7.1. NMEA0183 Data Sentences Supported.
2.2.3 External Silent Mode Switch
NMEA Port 2 can be used to allow the user to stop the unit from transmitting from a switch
mounted near the helm. This switch will take priority over ALL other user selectable silent
mode settings (though a mobile App or using the LED push button). Any latching double
pole switch will be suitable.
Silent Mode is selected when the switch is closed
The option for External Silent Mode Switch must be selected during initial configuration.
