Download

This function allows downloading of software changes and upgrades available from Orion’s website. To use this option, you must have the optional IntelliScope-to-PC cable, available from Orion. Check www.telescope.com for more information about available software downloads for the IntelliScope Computerized Object Locator.

Checksum

The checksum function is used to make sure that software has loaded into the controller properly. It has no purpose until a new software version is downloaded. Check the IntelliScope download section on www.telescope.com to see what the proper checksum should be for each new software version.

Rewrite

Rewrite is also only used after a new software version has been downloaded. It rewrites the new software into its memory in order to prevent any potential problems from arising after the software transfer.

Clock

This function allows use of the IntelliScope system with equatorial platforms for Dobsonian telescopes. If you are using your IntelliScope with a Dobsonian equatorial platform, press Enter when the selection “CLOCK” is displayed from the available “hid- den” function choices. The LCD screen will then show the word “ON” blinking. For normal operation of the IntelliScope system, the controller’s internal clock should be on. For use with a Dobsonian equatorial platform, use the up or down arrow button to change “ON” to “OFF,” and pressEnter. The controller is now ready to be used with a Dobsonian equa- torial platform. Now, when you press Power to turn the controller on, the LCD screen will state “CLOCK IS OFF” on the second line of its introduction screen.

To turn the controller’s internal clock back on, access the hidden functions, select “CLOCK,” pressEnter, change the “OFF” back to “ON,” and pressEnter again.
