Wiring for RAS SPID Rotator - BenningtonCS/Telescope-2014 GitHub Wiki

The document that came with the rotator can be found here for additional information on the rotator and wiring it.

Tool List

• Screwdriver (Phillips)
• Utility Knife
• Adjustable Wrench
• Small Screwdrivers (Phillips & Flathead)
• Soldering Iron
• Solder

Instructions

On the rotator, there is a plate with two screws and two waterproofed wire outputs. On the face next to the plate should be a sticker detailing the EL AZ wiring.

First, unscrew/remove the two waterproof outlets, and unscrew the two screws on the plate.

The edge of the plate may be painted over, so use a utility knife to edge the plate.

Using the back of a screwdriver, tap around the corners of the plate to loosen it.

Using a screwdriver or some other means of leverage, insert one end into a hole left from unscrewing the waterproof outlet, and pry off the plate. This may take some time since the plate has a tight fit.

Underneath the plate are two wiring terminals, one for AZ and one for EL.

Test Cables to Controller

A set of test cables were made, approx. 75 cm long. Our test cables consisted of four cables, each cable containing two wires, so there were two cables per terminal, or four wires per terminal. The ends of the wires were stripped and tinned.

The ends of the wires were secured in their respective rotator terminal.

The free end was then soldered to a head which connects to the controller.

The head was assembled and connected to the controller.

Once everything was secure and connected, the power supply and controller were turned on, with the mouse attached to the controller.

The 'F' button on the controller was pressed, and then the mouse was able to control the rotator!
