"TheSky" control of Celestron Ultima

[solissydney (Ken)]

Following Software Bisque instructions I am unable to make TheSky communicate with the scope. I suspect the problem is the wires in the RS-232 plug. Firstly I tried the yellow wire on pin 1, green on pin 2, red on 3 and black on 4. No good.
Then the green wire on pin 2, yellow on pin 3, red on 7 and black on 8. No luck.
The option is to connect pin 4 to pin 8, and pin 6 to pin 20 (20 ???) some misprint.
Can anyone help?

Post a phot of what you did - I thought there were only 3 wires to attach - not four and how is there pin 20 or a serial post?

Lastly - check you have the driver (teleapi.dll) added to the correct ASCOM directory per The SKy's instructions in teh read me file.

Attached to the laptop is a USB Serial Converter that, via a 4 wire cable, is inserted in the hand controller. No where in the Ultima manual is any mention of the file you mentioned, which is a Windows file. Also, I have not come across any ASCOM file??

Thanks

Ken,
You need the ASCOM drivers for The Sky. You can download it here.

Thank you for your replies and support. However, having installed the Ascom files, I fail to understand how that will help TheSky communicate with the scope, and help solve the problem of the pins-out in the 232 plug ???

Now that I have the correct pins-out I am able to control my Ultima using TheSky software. Bliss.
Matthew , you were correct in that only three of the wires are needed.

Glad to hear its resolved - still reckon someone should post a short article plus pictures on how to do this - so the next folk that need this information will find it easier to solve.

Any takers?

Cheers,

Be very very careful with with getting the pins wrong on on the serial stuff as you may just fry you mount.
