Please note that, as of 2011, I no longer support the Intelliscope driver.
I recommend David Ek's driver for those who may be interested.

David's driver may be found here:
ASCOM Driver for EkBox and Other Interfaces

ASCOM Intelliscope Driver Help File, March 2010

This file contains preliminary information about the current Imaginova driver for Orion Intelliscope. This driver should work with the following Digital Setting Circles (DSC): Celestron Advanced Astromaster, David Chandler Co. Deep Space Navigator, Discovery Digital Setting Circles, Grecner Navigator, JMI NGCMAX, Lumicon Sky Vector, Mountain Instruments Star Pilot, Orion Sky Wizard 3, and TeleVue Sky Tour, as well as BBox, Ouranos, MicroGuider III and V, and other similar units.

The Orion Intelliscope driver has been developed by Imaginova. It is based on an earlier ASCOM driver written by Dave Ek for his DSC interface.

Start by installing the latest ASCOM 5 platform. Next, be sure to install any platform updates that are available. At present this would be the 5.5.1 update. After installing the platform, please install this driver by way of the stand-alone exe installer Intelliscope Setup.exe Intelliscope stand-alone driver for ASCOM 5 platform

Be sure to enter your Comm port and encoder resolutions under driver properties setup screen. Different encoder resolutions are used on various telescopes, common values include 2048, 4000, 8000, and 10,000 (older DSCs may not handle 10,000 tic encoders). The encoder resolution for Intelliscope is 9216. You will not be able to connect to your telescope until you have specified non-zero encoder resolution and set the correct Comm port values.

You do not need to perform any DSC stand-alone alignment steps with your DSC hardware, because the DSC only sends raw encoder values to your serial port. You can skip the alignment star process on the DSC, and just follow the steps from the ASCOM driver.

On some DSC, you may need to set the vertical or horizontal position of the telescope and use the enter key on your DSC so that encoder readings will be sent for both Alt/Dec and Az/RA. If your tracking is bad, check your encoder values and try the driver setup screen option to reverse RA/AZ axis.
