Hello, I would like to enable contact closure output from HL2 when pressing TUNE button in PowerSDR. Is there a way to configure GPIO to do that?
I need contact closure for enabling 10dB attenuator to reduce external amplifier power from 270W down to about 15W. Drive setting is already set to 1 or lowest setting for TUNE function.
Another way to achieve what I want is to enable GPIO contact input that will place PowerSDR into TUNE mode. I guess that can be done via CAT commands? So I will need some kind RS232 controller to tell PowerSDR to go into TUNE?
