Anyone know if either of the Icom data jacks can be used to work with the URIx successfully for a simplex node? Documentation notes this: DATA IN - Input terminal for data (common for both 1200 and 9600 bps) GND - Ground line for the DATA IN, DATA OUT and AF OUT. PTTP - Transmits when this terminal is grounded. DATA OUT - Received data output terminal for 9600 bps operation. AF OUT - Received data output terminal for 1200 bps operation. SQL - Output terminal for squelch condition (Open/Close). Outputs grounded level signal when squelch is opened, +8 V level signal when squelch is closed. I wired it up but not getting tx audio or rx audio to work. Tried using SQL with the URI COR_DET line. Maybe that's inverted here... Anyone have luck using this kind of data port to do the interfacing? thanks!
