Connecting NMEA 0183 from nexus classic

[daydreamerjr]

Hello,

I have a Nexus Classic server on my boat and I would like to connect a WiFi Bridge I purchased the WiFi bridge connections are:

NMEA IN+
NMEA IN-
NMEA OUT-
NMEA OUT+
Question I have if anybody has connecting that format to a nexus server. This is my box:

I have tried wiring it assuming that the returns were the (-) that did not work. I’m wondering if it’s an RS232 vs RS422 thing and I need a bridge and if so how would I even wire that. I apologize if this has been asked before.

Anyone?

Did you realize that IN on the server needs to get the OUT from the WiFi and same the other way?

Senang, I am aware. So in doing some digging it would appear that it is a single ended connection (rs232). It looks as though I need to jumper pin 10 with pin 12. Then the output and input then become single ended.

I just ordered a converter between rs232 and 442. In the interim I’m going to jumper it then connect the (pin 11-out) on the gateway NMEA IN+ and (pin12-ground) to NMEA IN-. In researching this I have found numerous write-ups that say you can make them communicate this way. Alternative I may use my old chart plotter (garmin 540) and see if that will connect.

I am not aware if I can post a link to another nautical website, but in this link you have some usefull information about NMEA0183 and RS422 networks.

Questions seem to come up on occasion about wiring for NMEA , and use of RS-232. Hopefully this article will help understand the issue and be of use for other folks setting up an NMEA network on their

daydreamerjr were you ultimately able to connect your Nexus Classic to a wireless bridge? If so, which bridge? Thanks.
