- 36 - APPENDIX D: PERSONAL COMPUTER (PC) CONTROL OF THE #1697 CDS Remote operation of a computerized telescope has only been a fanciful dream for most amateur astronomers. The realization of fully controlling a telescope through a personal computer has previously been a staggering proposition involving high monetary cost and expert knowledge of software and hardware.
- 37 - 2. CDS Test Program Once you have the RS-232 cable constructed, you will want to test the cable. Below is a simple program called "CDS TEST” that is written in GW Basic programming language and will work with virtually any IBM compatible computer. CDS Test is an effective program to fully check the RS-232 line communications from your personal computer to the CDS, allowing you to concentrate on de-bugging your RS-232 cable.
- 38 - 3. CDS Command Set Intended for professional programmers, the CDS Command Set is used to write custom software for remote operation of the telescope with a PC. Each command is listed in a section appropriate to its type. Each entry in the command list includes the command name, any parameters, any return values, and a description. The parameters and the return data are shown in a manner that indicates their format.

- 50 - APPENDIX E: CARE AND MAINTENANCE OF THE CDS 1. Keeping Your Components Clean Prevention is the best recommendation that a telescope owner can follow in keeping astronomical equipment in top working order. Proper measures taken during observations and when storing the equipment between observation runs can ensure many years of trouble free use. Dust and moisture are the two main enemies to your telescope and electronics.
NOTICE This equipment has been tested and found to comply with the limits for a CLASS B digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses, and can radiate radio frequency energy and, if not installed and used in accordance with the instructions contained in this manual, may cause harmful interference to radio and television communications.
