Hi,
I have a problem with FS2 controller
the version of FS2 is 1.26.
The controller is connected to the pc via serial/usb adapter.
The Kstars version is the 3.5.8 and the Ubuntu version is 20.04.4
After the connection with indi Fs2 it does the sync and goto only once, then it stops responding.
Who can help me?

Ciao Raniero!

The FS-2 provides two LX200 modes. One is xx:xx,x and the other is xx:xx:xx. They can be set in the menu. The FS-2 driver requires the FS-2 to use the xx:xx,x format.

Hope this helps.

thank you very much Alfred, I'll try!

hello Alfred, i tried changing the settings of FS2 but the result is the same.
it seems that the system is losing the serial port

Hmm, maybe a cable or serial/usb adapter issue? Do you have an alternative adapter to test?

I tried with the direct RS232 serial.
i will also test an adapter
