Bart,
That was my suggestion, and it was only a post on the reflector, I did not
write up anything further.
The details are as you recall - Pin 4 is not used, so that is the one to
sacrifice. To plug the hole, you can use most anything, a whittled down
piece of toothpick for example. I used a bit of wire just large enough to
stay securely in the hole.
I have also implemented a different cure - I just made a short IO cable
(about 5 inches long) that is permanently screwed onto the KIO2 connector,
the short cable is built just like the normal K2 cable except that I
connected the shield on both ends. Since the wires that may damage the K2
are not connected in this short cable, any normal RS-232 cable can be used
with no harm, but for shielding/isolation purposes, I use the normal K2 to
PC cable.
So now you have 2 ways of providing protection - take your pick.

I seem to recall that somebody somewhere reported adding a safety measure
to the IO connector and the matching cable. It involved plugging one hole
in the K2's IO socket and cutting a pin fom the corresponding connector on
the cable, I think.
The idea was to prevent one from using any old cable in a moment
of -let's-get-it-going- rush, a phenomenom we all seem to recognize... ;-)
Anyway, being in the proces of building the KIO2, I cannot find the
article anywhere but contemplate implementing such a safety feature. I
wouldn't know which pin to sacrifice (might take one out that is needed in
a future application). Any pointers from the list?
Best,
Bart de PA3GYU
