I wanted to hold off on this until I had the encoders mounted. Once the encoder and encoders are mounted on the dob I did'nt want cords hanging everywhere and to have to drill holes larger than the cable itself but, at the same time I need to test the encoders and the board itself hooked up.

I cut a pair of 4 pins to mount to the board, if you look at the bottom of the board the N/C, and ground are shorted, only 4 pins are needed and the part you ordered(if you used Dave Ek's part list which was spot on, no problems) is for 4 pins.

Two pairs of 4 pins cut to be soldered to the board.

Test fitting the 5 pin connector to the encoder, note one computer pin is partially sticking out of the hole.

Both the 4 connection with the jumper pins and computer pin and encoder pictured

The two pairs of 4 pin jumpers soldered to the board. NOTE: I had to drill slightly larger hole's than the normal holes drilled like for the serial connector. Just be sure they are not any larger than they have to be, and check the bottom of the board just to make sure you are not messing up the traces. After you have drilled scrape lightly with a small wire brush before soldering. You want to select a bit, that is just larger than the hole, before you use it match it up with the solder pad on the bottom of the board to make sure your it's not too big and your going to drill thru the pad.

Again, the Ground and N/C connections are connected if you look at the bottom of the board, this is the correct placement of the pins (or you could just clip off 5 of them solder all 5 but, this makes it less confusing (esp) if you should have to hook it up in the dark.

For this I am using US Digital Cat-3, I have a few hundred feet in a 1000 foot spool (well less now, it was free)

It has eight wires I only need 4, so I keep the color coded wires clip the 4 white wires and the fuss.

If you get a chance pick up a variety pack of heat shrink tubing for cables I try and use it whenever I make cables but, it's up to you.

I cut a small piece of heat shrink tubing that fit and placed it a ways up, clipped the extra wires and fuss, then stripped the wires for attaching computer pins

Computer Pins pictured, they come on a strip and you just break them off as you need them, and crimp them on. If you don't have a crimper, simply use a needle nose, it works fine takes a little longer to do it right but, while the $10 crimper in Dave Ek's list is a good deal if you do alot of crimping it's probably a waste of money for a one time use.

Cable with some pins attached, might not be bad idea to order and extra four pin, a five pin, and extra computer pins (they are cheap)

Pins attached, heat shrink covering, non shrunk

Cables done, I might be able to put a large second layer small band of heat shrink around the connector to seal all the wires, you don't want these shorting, or just wrap, a piece of electrical tape aroud the very end including a small portion of the connector.

Triple check the connections, first make sure you have continuity from one pin to another but, then also check you are placing the pins in the correct hole. The cable pictured here has two pins in the wrong order.
