Group (http://tech.groups.yahoo.com/group/CelestronCompustar-User/). Mr. Borgman published

this in response to a request for autoguiding wiring posted on the Yahoo Compustar User‟s

Group. He indicated that he had done this wiring for an observatory in Texas and would be

happy to share the schematic.

The diagram has two portions. It shows the wiring scheme for an autoguider relay box, or

interface box, on the right side of the diagram and, on the left side of the diagram, the wiring for

an optional joystick that can be plugged into the joystick port on the right side of the Compustar

computer module. We will be interested in just the right side of the diagram. However, his

diagram showed how to wire the relay box from either RJ-11 pins coming from an ST-V or the

DB-9 male pins on an SBIG ST7, 8, or 9. They all use autoguider languages other than the ST-4

language we will be using, so we can‟t use the pin out wirings shown (still labeled as RJ-11 Pins

for ST-V and DB-9 pins for ST7,8,9 in small print on the upper right of the diagram).

The wiring diagram has been modified to show how it should be wired to work with an RJ-11

cable using the ST-4 language. This is indicated by “RJ-11 Pins” printed in larger font at the

extreme upper right of the diagram. Beneath that are the pin outs for the RJ-11 cable we are

using, and the connections to the relay box are shown with colored lines corresponding to the

corresponding wire colors on the RJ-11 cable.

The relay box with the relay circuits and other parts will have to be assembled from parts by the

reader, provided they are competent at interpreting these diagrams and translating them to

circuits. For those who are not, like the author, it should be built by some competent individual, -

like an electrical engineer. The parts list for this relay interface box is listed below.
