Aha!!!! I have just found out that the cable in question is NOT the celestron serial cable with the 9pin serial to 4pin phone connector!
It is the celestron PROGRAMMING cable with the 9pin serial to 8pin phone connector.
It plugs into the pc port of the telescope, not the hand control port in the fork arm. Why they complicate these things is beyond my comprehension. As if these scopes arent complicated enough!!
Maybe I should have spent those big dollars on a simpler scope with twice the aperture!!!
