COM 1 ports for rotator control

[Dieter]

I am trying to control my Yaesu G-2800 DXC rotator with Yaesu computer controller GS-232 B, using the COM 1 interfaces of the two RRC's.But it doesn't work.I configured both boxes as follows: 9600 baud, 8/1/0 bits.I tried all modes from mode 1 to mode 5, but nothing worked.If I connect the two straigt cables (the one from the computer to the one to the GS-232 B rotor controller, it works.I tested the output COM 1 (Radio Side) with a scope and found no signals, but there are signals at the input COM 1 (Control Side)

What is probabely wrong ? Any help would be appreciated very much.

Hi

If you check the pin numbering on the connector page, you find out that you can not use a straight cable from RRC to rotor. The one from PC to RRC can be straight.
