Raymarine c95 lost depth after adding AIS

[DaveyG]

anybody know why this has happened, or how to fix it ?

The plotter says look in the manual for e22158-seatalk-stng-converter, but the manual offers zero help

Thx

Was the AIS added by connecting via seatalk, seatalkng, or nmea?
NMEA you probably disturbed the old wires, or tried to double up an input.
Seatalkng, could you have missed out the backbone terminator? Are other instruments working?
Seatalk is supposed to be daisy chained, in one out the other, with no loops.

In the menu's there is buried somewhere settings for where it gets input from, if you moved something from one port to another that might need resetting, although it's normally on auto.

The baud rate of the AIS will be 38400, the depth might be the more traditional 4800 if you've wired them together they would interfere like that. If the rate is the same you sometimes get away with it.

Checked all connections - were good. Disconnected AIS and it all worked, depth is displayed on plotter. Connected it all and lost depth again, scratched head.
Was told to set baud rate on the plotter to 38400, so thought I'd see what happens if set to 4800, and it all works again, plotter shows depth, AIS is all recieved and transmitted.
Could there be any other impacts of setting the baud rate at 4800 instead of 38400 ?

At 4800 you might miss some AIS updates, possibly leaving it more out of date than it could be.

It sounds rather a lot like you've doubled up an nmea input, which you aren't supposed to do but often get away with.
