Dear OMs,
I am a very, very new SunSDR2 Pro user (1 week old).
I just wanted to share with you and to confirm to you one interesting solution which might help
Microham STATION MASTER and/or Ultrabeam/Steppir users.:
Yes, Station Master can be connected to SunSDR2 Pro, so it can control Ultrabeam and/or Steppir Antennas (and rotors and various other things).
I have a bit complicated system: Ultrabeam and Yaesu Rotor connected to Station Master and Station Master to PC and of course SunSDR2 Pro to PC.
I wanted to have a system, where I can “tune” Ultrabeam, either from ExpertSDR OR from my logging program (UCXLog, HRD) and can also control rotor from log program (DX cluster).
With the help and kind advices of Björn SM0MDG

and Jozef OM7ZZ (of Microham) I could do it!
If you need similar system, you will need following:
-Microham cable CAT RS232-YX ("crossed” cable) this cable connects PC to Station Master
-either RS232 connector on your PC or in my case a Prolific USB-to-Serial adapter
-VSPE or other virtual port program
In VPSE I created „Virtual Connector” in my case COM6.
ExpertSDR is connected to COM6 and also my log program is connected to COM6.
Than -again in VSPE- I created a „Serial Redirector” connecting COM6 to COM5 (which is address of USB-to-Serial adapter.
So basically ExpertSDR emulates a Kenwood TS-480 for Station Master.
Do not forget to set physical jumpers in Station Master for RS232 and also in Station Master software setting Kenwood TS480.
I also found out I needed to download Prolific Windows 10 driver and „Stock” WIN10 drivers did not work,
73!
