GTO Keypad Freezes Problem
Terry Johnson <tjohnson@...>
Marj, I spoke with Roland about a problem I was having with my 600GTO mount. The problem centers around the GTO keypad. I have explained the problem below in more detail. Would you please see that he gets this information. I will also provide a printed copy when I send you the equipment he requested.
I was just completing a polar alignment process using the north polar alignment procedure, I was using Polaris and Vega as my two stars, as I was doing a final alignment on Vega, and was asked to press 'menu' to have the scope slew to polaris for the final time, I pressed the 'menu' key on the keypad and nothing happened. I pressed the key several more times and still nothing happened. I pressed other keys and still nothing happened. The keypad was locked on the 'press menu to exit' command.
I was able to get around the problem by turning off and on the power to the GTO control box. I now had to polar align again.
Since I was very near completing the alignment in the previous aligning process, it did not take long to polar align this time. After aligning, I slewed the scope to Vega. I then added the additional equipment for taking exposures(see Equipment, after polar aligning, below). I was going to slew to another location in the sky, however, the keypad was lock up again while on Vega. The problem was the same where the keypad was locked on the 'press menu to exit' key.
I gave up for this evening, packed up and went home.
The next night I was able to polar align correctly. I then added my guiding equipment for camera exposures (see Equipment after polar alignment, below) I slewed to arcturus to practice my guiding on a bright star. After having success on the guiding practice, I decided to take an exposure of M-13. I keyed in M-13 using the keypad, pressed the 'GOTO' key and the scope did not move, however, the keypad did display the information about M-13 as it normally does after you press the 'GOTO' key. I pressed other keys and still no response. I had to power off/on the GTO control box to clear the problem.
I would appreciate any advice or experience on what is causing this problem. Roland has asked that I send in my keypad, cables, and GTO control box to be checked out. I will send the equipment in tomorrow.
Thanks for your help in this matter...Terry Johnson
