You really need a special cable where only Send data, receive data and
ground to the computer. On a DB25, this is pins 2, 3, and 7 that should
be the only ones connected to the computer serial port.

The 301 remote tuning knob uses DB25 pins 6 and 8 for the encoder signals.
If I run a Y splitter off the Omni 6 DB25 and connect both the 301 and a
computer, the 301 stops working. Pins 6 and 8 normally carry DSR and CD
serial signals so connecting to a computer will interfere with the encoder
signals on those pins. Can anybody explain the proper way to handle the
Pin 6 and 8 connection in the cable that goes to the computer if a 301 is
also connected to the Omni 6 port? Or are pins 6 and 8 SUPPOSED to be
disconnected in the Omni 6 serial cable?
Thanks& 73,
