No, I did not put the HC in PC direct mode. I wanted to use the mount in Alt-Az mode. I only use the eqmod direct connection for equatorial mode.
When connecting with the Synscan driver, you first have to do the alignment procedure via HC, than you should be able to connect to the HC without going in PC direct mode. The PC direct mode will bypass the HC. One can do this as an alternative to the eqmod direct connection for eqmod.
Just wonder, why I can´t sync.
