RS2. Serial connection to Lawrance (NMEA0183)

Hi!

We are trying to connect our Emlid RS2 to an echo sounder (Lawrance HDS 12 Live). We have followed this guide: [https://blog.biobasemaps.com/2019/01/03/networking-3rd-party-gps-gnss-into-lowrance/]When we are trying to stream the positions the Emlid app says “Stream is off”. I can’t see what I’m doing wrong in my setup.

The output position settings are set to:
Serial.
Device: UART
Baud rate: 4800
Format: NMEA

I have attached some photos of the “problems”.

Are there any who how an idea of what I’m doing wrong?

Thanks!

Best regards
Mikkel Knudsen

Hi Mikkel,

May I ask you to share your hardware setup photos? I’d like to check the Reach RS2 to an echo sounder connection: just to exclude any possible issues with that.

Also, I’d recommend double-checking you specified the same baud rate on both devices.

Hi Tatiana.

Sorry for the late answer.
I checked the baud rate and it is the same on both devices.
I have taken some photos of the connection and the setup.

Best regards

Hi, Have you read this

Hi Mikkel!

According to the tutorial you mentioned, the Reach RS2 should be a Talker in the scheme. So, it is necessary to connect Reach RS2 TX wire to the adapter RX+ wire. The RX- adapter wire should be connected to the Reach RS2 Ground pin.

The pinout of the RS-232 port of RS2 might be useful for you.
