Prior to installing the 360 transducer and heading sensor,
my GPS puck would communicate location data to my vhf marine radio,
the nmea 0183 location using 4800 baud rate that the radio requires.
There are no optional baud rates.
Since installing the 360 and GPS with heading sensor,
the 1198 now sets the baud rate to 38,400 for everything when nmea is set on
which my vhf marine radio needs to receive the location data.
Question, is there a way to get the location data from the 1198 or heading sensor pigtail
by using a different connection point on the 1198 to get 4800 baud rate.
I have most wires available to try patching something together.

George,
I believe that GPS Receiver is only capable of the 38,400 baud rate.
Suggestion: You can connect up your old GPS Receiver and use it again for the NMEA 0183 input to your VHF DSC Radio.
Which GPS Receiver do you have?

It came with the 1198
AS GRP is on the underside.
This is the one that previously worked with the VHF radio

baud rates 4800 9600 38400 are available if NMEA is off
baud rate 38400 is the only one available if NMEA is on
Unfortunately, I need to output the NMEA at 4800 baud
It would seem that this is a software switch being set that maybe could be altered in the future
to allow this capability to return for use.

I went through the same thing late last year.
The HS puck would not work with my radio do to the baud rate.
My fix was to install the HS puck to my console 998 and the standard puck to my bow 958. The two units are connected with Ethernet. I spliced some wire onto the bow puck and ran it back to the console and connected it to the radio.
The main drawback was that the bow 958 had to be on when ever I wanted GPS to the radio.
Therefore, this spring I purchased a new radio with GPS built in. I'll sell the old one on eBay.

You could just connect the AS-GRP you have to the boat’s 12-volt system (through a switch) and use the NMEA output from it for your DSC radio. Would be cheaper than buying a new radio.
