How to export rtk NMEA0183 from teensy to rs232

Just wondering if anyone has got the nmea out working on a board with dual receivers?

I too would like to know if this is working reliability for someone. I’d like to upgrade to dual but have everything working well on single and don’t want to break it.

I’m looking at being able to send VTG, RMC and GGA (looks like wiht GP prefix) to a SeedSense 20/20 for planting next spring. What is the current recommended approach. Still using UART2, or with the GPS out functionality in AgOpen, is there a way to have an ethernet to Amphenol 4 pin GPS signal plug? i’d like the 20/20 to be using the exact same corrected values as AgOpen does.

GPSout works fine for us on a gen 2 20/20 and gets you roll correction.

Any help on the wiring and how to make that connection. I’m struggling to understand the wiring for what it would take to connect the GPSout to the 20/20 4 pin amphenol
thanks!

I used this cable. Probably could make your own though.


Also need usb to db9 cable

Here is some info if you are wanting to build your own cable

I’m sure there is a simpler way to do it, but we have a usb to 9 pin rs232 serial cable on the tablet, and then this adaptor on the precision harness.

Thanks. Seeing if I can find a used cable – be simpler than making one. I already have the USB to DB9 adapter cable.
