The computer cable for the K2 requires only three wires connecting pins 2, 3 and 5 on each end. The other pins must not be connected since the KIO2 signals on these pins are not RS-232 capable. Connecting them to an RS-232 connector will cause damage in the K2.
The K3 can use a standard RS-232 cable. A standard 9-conductor straight-through cable will work just fine. AD5SS is correct. While the KRC2 and Transverters can connect to the K2 using a short straight-through cable, you need a two conductor cable connected to the K3's Aux IO port to use these devices with the K3. Hope this helps. Jack Brindle, W6FB Elecraft Engineering On Mar 18, 2010, at 2:25 PM, K. Edwards wrote: > I have a K2 and a K3.
