After spending several hours wiring up my first control panel I was down to my Happ trackball and Slikstik Tornado spinner. So, since I had never done this before I went to Ultimarc's website and downloaded the following directions:
Connecting a Happ trackball
The Happ trackball is supplied with a connecting cable. Cut off the large plug mounted on one end. Strip a short length of each wire and connect as shown in the table below. Set the jumper to "A/LO".
Black (2 wires) Red (2 wires) Purple Blue Yellow Green
GND +5V X1 X2 Y1 Y2
There are two +5V and GND wires. These can both be connected to the same +5V or GND connection.
The Happ trackballs have a green ground wire. This is to prevent static buildup and can be connected to any convenient ground point.
Set the USB/Serial jumper to the correct position for the interface and cable you are using.
Plug USB cable into the "Port 1" connector on the board and connect to the PC USB port. The PC will auto-detect the device and install a standard mouse driver. (Actually it installs two mouse devices)So without any further thought I chopped off the end of the trackball connector. Unfortunately I didn't find all of the wires that they had listed above.

I only have four wires: red, black, white and green. It was about this time that my stomach dropped through the floor. My Happ trackball had a USB connector on the end of it and I'm very concerned that I have really screwed this up.

But the story does not end there. Hoping to recover from this setback I then moved to installing my Tornado spinner so out come the wire cutters, and clip..... Dang it, it only has four wires as well.
Wait, it continues to get better...So I spend the next 30 minutes wiring these very small wires (must be like 80 gauge wire) into my Optipac and I finally get it wrapped up. So my next step is to hook my Optipac and I-pac up to my computer. I've got a keyboard cable to hook up the I-pac but I have no serial cable to hook up the Optipac. So, I spend the next 45 minutes tearing the house apart and looking in the garbage for a serial to USB cable. Arrrrggghhhh

there is none to be found. So, I send a message off to Andy at Ultimarc to see if he is willing to trade a keyboard cable for a USB connector.
Now I get up this morning and realize that I may have screwed this up big time. Please tell me that I haven
