Hi there:

Is is possible to control Rotator (COM1) and CAT (COM2) using the same cable conected to the Control RRC mini usb at the same time?

I hardly remember that was possible, but I'm trying to do it (for my friend @ea5zj) and doesn't work.

System is working with two separated cables on control RRC:

  • Mini USB for COM2 (CAT)
  • USB FTDI converter for COM1 (Rotator)

But would be easier and cleaner with only one usb conection for everything....

Is it possible?

Hi Juan Carlos,

It should work. You need to make sure that in the RRC serial port menu that COM1 "use USB com port as COM1" is set to YES.
Is it set correctly? If the FTDI converter is being used, then it needs to be set to NO and maybe you forgot to change it.

Hi Mitch:

Unfortunately, is not stable enough....sometimes works, but sometimes doesn't work....I don't know why.

With two different cables, even with a prolific one on COM1 (the one we have at home), is working.

Many thanks

Hi Juan Carlos,

The instability issues are usually caused by Windows and can often be solved by making some changes to the
Windows settings. See the following excellent presentation by N6TV for tips on how to make the changes:
https://www.kkn.net/~n6tv/N6TV_Dayton_2020_Everything_USB.pdf
The relevant part starts at page 26.

I hope this helps.
