I usually click the "Now" button in the AP V2 window, which as I understand it does something similar to the Auto-Config, except as a discreet one-time command.
My setup routine is as follows:
The other night I wanted to try connecting the AP V2 Driver dirrectly to the mount through the ethernet cable instead of through the virtual COM port in APCC. I changed the COM setting in the AP V2 Driver to use the IP address and it worked fine. Now I want to go back to the normal setup described above, but for some reason the AP V2 driver COM settings are "stuck" on the IP address mode and every time I change them back to the APCC virtual COM port they revert back.
