[TG] [TG11] AIS700 integration c80 not getting GPS fix now

[Tom - Raymarine - Moderator]

Hello Swish,

The problem here is that by setting the C80's input speed to 38400baud for AIS, that input is no longer compatible with standard 4800baud NMEA0183.

What you need to do is connect the NMEA0183 devices to the AIS700's 4800 input and output (in the same way they were previously connected to the C80's input and output), and connect the AIS700 to the C80 over 38400 input and output (you currently have the C80 input connected, but perhaps not the output.)

The AIS500, AIS650 and AIS700 included internal multi-speed NMEA 'multiplexers' for exactly this reason, and this is one of the advantages of having bought an AIS700 in the first place over another brand. The C80 will transmit receive and transmit at 38400 with the AIS, and the AIS will convert this to/from 4800 for the other devices. The AIS700's handbook calls the 38400 channels 'HI' and 4800 channels 'LO'.

Tom
