SkySafari 7 Pro supports Ascom, so it is best to make a connection in that way.

The mount needs to have correct date, time and site information before it can perform GOTO correctly. The 8401 HC has a backup battery to remember the date and time between the sessions. The site information includes longitude, latitude and time zone offset, will be stored in HC flash memory until you change them.
If your GoToNova kit equipped with an optional GPS receiver (#8411), the hand controller will receive the local time, longitude and latitude information from satellites after the link is established.
The iOptron mounts may be controlled by a number of popular astronomy software programs. For astronomy software that does not have an embedded iOptron mount driver, an ASCOM driver and related platform are needed. Please refer to Appendix F for more information.
Appendix F. Use a PC to Control an iOptron Mount
In general you need the followings to use a PC to control an iOptron mount:
- A GoToNova Hand Controller with USB port, such as 8402 or 8401 Hand Controller;
- Download USB2COM driver from iOptron website http://www.ioptron.com, click on Support, select GoToNova Hand Controllers.
- For 8401, 8402 hand controller, download cp2102.zip or CP210x VCP driver
depends on your windows operation system; - For 8402G hand controller, download PL-2303 VCP driver
- For 8401, 8402 hand controller, download cp2102.zip or CP210x VCP driver
- Install USB2COM to establish the connection between the mount and the PC;
- Download and install ASCOMPlatform5b.msi from http://www.ascom-standards.org/
- Download and install ASCOMPlatform5.5.1 Update from http://www.ascom- standards.org/.
- Download and install iOptron Telescope ASCOM drive 1.03b from iOptron website, click on Support, select ASCOM Driver.
- Please remove previous installed iOptron ASCOM driver before installation
- If your computer does not have a Visual C++ 2008 SP1 Redistribute, which gave an
error message during ASCOM installation, you need download and install one from http://download.microsoft.com/download/d/d/9/dd9a82d0-52ef-40db-8dab- 795376989c03/vcredist_x86.exe.
- Planetarium software support ASCOM protocol. Follow software instruction to select iOptron Telescope.
