This sounds all noob but I’m soldering a 9 pin sub d connector onto my A032 so I can plug it straight into the back of my Seatracer AIS but I’m a bit unsure about where or if the A032 ground wire should go? I also want to check the A032 receives the AIS transmit and transmits to the AIS recieve like a plotter would or as it’s a multiplexer or is it TX to TX and RX to RX?
So A032 being first
Blue to Blue or Blue to White
White to Yellow or White to Green
Black to White or Black to Blue
Grey to Green or Grey to Yellow
Brown to where?
Apologies in advance, I would/should test it on the boat before but I’m 100 miles away (I probably will actually)
Kind Regards Tom

I would suggest you try firstly:
A032 TX- —> Seatracer RXa
A032 TX+ —> Seatracer RXb
A032 RX- —> Seatracer TXa
A032 RX+ —> Seatracer TXb
If it won’t work, please try swap + AND – on each pairs.
If it still won’t work, then please try:
A032 TX- —> Seatracer RXa or b
and then GND to the other RX on Seatracer.
A032 RX- —> Seatracer RXa or b
and then GND to the other TX on Seatracer.
Keep us updated please.
Good to know I’m not being stupid, I assume most nmea devices run a ground/shield wire then? I’ll test the combination before soldering the plug onto the A032.
I have had the Seatracer sending AIS data to a Standard Horizon CP180 by connecting the Seatracer Green TXa to the CP180 blue port 1 input and the Seatracer White TXb to the CP180 Green NMEA common.
Another couple of questions
1. Can the A032 be powered through the USB or solely through the nmea plug? I’m still waiting on a lead to try the connections.
2. I noticed in the Seatracer instructions I posted above it says you can wire an NMEA0183 4800 (wind data) into the RX and it’ll multiplex it with the AIS info and send it out. I’m wondering if I send info from the A032 into the Seatracer will it then duplicate the information back to the A032 confusing things especially when connected into the NMEA2K? (or does the A032 only transmit the same baud rate as it is programmed to recieve?)
Maybe it’ll be better to leave the Seatracer RX wires off the A032 and have them seperate incase I need to feed other 0183 stuff through the Seatracer in the future?
I’ll certainly test the connections and report back when I next get down the boat.

Hi A032 needs to be powered through N2K network. USB doesn’t have enough current to power it up. Regarding to your second question, I guess you need to check it with Seatracer AIS. Thanks for your understanding.
