Getting nmea data out of Signal K/OpenCPN

Node red is fantastic & extremely powerful, but you shouldn't really need to use it for data apart from deeper fiddling. Well worth investigating though, can be useful for problem solving. 

Did you solve your problem yet?

No, I can't seem to establish data out of OpenCPN.  Full data in, everythign working, but nothing back up to the usb bi directional multiplexer (and on to autopilot) and nothing to the VHF down the usb rs485.

Frustrating with the VHF, clearly debug mode shows data flowing down the usb rs485 cable, the cable itself has led indicators that show data arriving, but no GPS data at the vhf.  I checked continuity, even swapped over the wires, but nothing.  Having GPS at the VHF in iteself isn't critical, but if I could get it to work I know I could also get the autopilot working.  At the moment I cannot confirm that OpenCPN is sending data back up to the bi directional multiplexer.
