This is a new 6300 which is up and running with DDutil 3 and DAX to control the PW1 frequency and connect to PC software. But, it does not key over the PTT cable and TX 1. I checked the voltage on the PTT line and it reads about  3.5V DC constant, even as I push the MOX button on SmartSDR. I can key PTT on the PW1 by grounding the cable. I tried all of the recommended software settings in these posts. Is it a hardware issue or other? Thanks. 73, Bruce K6ZB

You need to enable the PTT Line in the startup screen

AND you need to have DDUTIL set to OPERATE which activates that line
