Serial data in and out?

[affinite]

Hi, I am currently running OP 1.0.0 alpha on a RP3 and it works fine with GPS and AIS data in from my em-trak B100 AIS transciever connected with an USB to serial adapter. I would also like to send NMEA 1083-data out to my Raymarine ST1000 autopilot.

In Openplotter i have got one serial connection and 3 Kplex connections added automatically but I can't change the serial connection under Kplex to be both in and out. 

Isn't it possible to have one in/out going serial connection? If it is, how do I set it up? All the wiring is done and worked when I sent NMEA fronm my old GPS to the autopilot.

II have a similar setup to you.
GPS,AIS and Raymarine instruments
've now moved onto OP2 but I still have a copy of my old kplex.conf file from OP1.2.
From memory I think you need to go into USB manager, advanced settings.
This opens kplex.conf for manual editing.
In there, define a port like mine below. 
I called mine "Seatlalk" as I use a NMEA/Seatalk bridge ti link to my Seatalk instruments and Autopilot
