There was a another suggestion made, that I've done. Cut a slot in the shell of the male connector directly above pin 3, and solder a bit of wire for a key onto the shell of the female connector.

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. 73, Don W3FPR ----- Original Message ----- > > I seem to recall that somebody somewhere reported adding a safety measure > to the IO connector and the matching cable.
