Hi,

Please ensure baud rate is set to the same speed for both the A032’s output and the VHF radio’s input (4800bps or 38400bps, if high speed data transfer is required, e.g., for AIS data).

If the connection does not work, swap the NMEA + and NMEA – data wires:

A032 NMEA 0183 OUT+   ->   VHF radio’s NMEA IN-

A032 NMEA 0183 OUT-    ->   VHF radio’s NMEA IN+

Please switch off your devices and disconnect them from their power supply before connecting/disconnecting data wires.

Hope this helps.
