Let's see if anyone here can help me avoid killing my 203v's!!

I need to know what the cat hair is "disable"?

And to what exactly do I connect to terminal 10?

5vdc? ground 5 v? pin 18 thru 25 on the printer port?

The instructions could be a whale of a lot more concise, considering the price paid!! (just a little annoyed!)

jb,
You are using a breakout board aren't you? If not, I would strongly advise that you do. The breakout boards make life so much easier. Although the G203 doesn't require the 15mA drivers of the older products, it's sometimes nice to have a breakout board just as an insurance policy to protect the computer.

On the G203, Terminal #10 is signal ground. It is connected to the ground connection on the power supply that drives the Step and Direction signals. Quoting from the 'manual': (TERM. 10) COMMON Connect this terminal to the controller ground output.

The PMDX-122 breakout board that I use has a jumper to select between using 5V or 0V as the COMMON.

Once you've had a chance to work with the G203 a little, I think you'll be very pleased that you picked that model. I have four G212s that were converted to G202 by removing the pulse multiplier boards and I have four G203s. Both do a perfectly good job, but the G203s are smaller. The G203s run cooler. The stepper motors 'sound' smoother when connected to the G203s.
