Yes just having a look at the specs for you digital yacht ant200. It does output RS232 signal however we feel it can be sorted without the use of the bridge device.
1. On your ant200 You should have a wire that is NMEA OUT+ (according to the specs is grey) which we would ask you to connect to the NMEA IN – on you A031 device
2. Secondly on your ant200, wire the NMEA OUT- to the POWER – on your A031 device. (please make sure it is in the POWER- part of your device. Else the device will be damaged by the current)
Please let us know how you get on.
