\Screaming mode on\ Be careful. The DB9 socket on the back of the K2 is ***** NOT ***** RS232. It's proprietary. Pins 1, 4, 6,7,8 are used for proprietary purposes and it's possible you can ***** SMOKE ***** your computer or K2. You ***** MUST ***** use the method in your manual or its equivalent to split off ***** ONLY ***** 2, 3, 5 for RS232 use. ***** YOU HAVE BEEN WARNED ***** \Screaming mode off\ Some people have gone so far to plug up one hole in the socket so a regular DB9 male plug simply can't be inserted accidentally. Some years ago, when the KIO2 was new, there was a regular smoke-em parade of those who had ignored the admonishment and burned something up. Some folks did it two or three times. In WWII the military solved this ghastly problem by having a gazillion multi-pin plug and socket layouts, so you could ONLY plug something in where it actually matched up wire for wire. If your dog could get the plug in on his own it was right. No doubt saved a few lives. 73, Guy.
