Dick,
Not really being a wiz at this the only thing I might think of to try is to
maybe see the set up works with an ASCOM driver.

Subject: [sac-forum] Anybody Got an Idea?
Hi, All.
I have a Celestron C11 on a CI700 mount with an NGC-Max digital setting
circle control. I used to use it with an old Laptop using TheSky 6.0. My
old laptop had a serial port on it, so the RS-232 cable was a direct
connect. All was going well until my laptop entered a black hole this
summer.
The new one, of course, does not have a serial port ("What's that?" asked
the clerk.) So I got one of Thomas Hilton's RS-232 to USB converter
adapters and installed it on my new laptop (a Dell Vostro).
I set up TheSky's Telescope setup dialogs as I had before, but now when I
sync the laptop with the scope, strange things happen. At sync, the Warp
(or "difference") is in good agreement with the NGC Max. But when I start
to slew, the RA and DEC readouts (in Telescope, Digital Setting Circle mode
in TheSky) change WAY too fast. For instance, a slew of 30 minutes in RA
causes a 4 HOUR change in the readout, and a slew of 20 degrees in DEC
causes a 40 or 50 degree change in the readout.
I am at a loss to figure this out, having tried all sorts of tweaks in the
setup dialog. My encoders are hi res (4,000 tics per rev).
Anybody have any suggestions?
