Mike, I purchased one of these 3 way cables from the web site below and it arrived yesterday. I got both the serial port from the PC and the 301 encoder connected to the cable and the cable plugged i
Does the 301 work if you plug it thru the Y-adapter and have the other side of the Y disconnected? If not, then you may have gotten a cable that does not have all the pins wired. 73, Duane On Tue, 4
