If the RS-232 is only using GND and TX/RX (cw switching), how does it
get rig control info from software like DXLab and HamRadioDeluxe?
I've heard you could fry the K2 RS232 board by using the wrong serial
cable - which I think is a design flaw as these cables (null modem vs
straight through) are not marked differently so it's easy to make a
mistake.
Should I open the cable I'm going to use up and make sure only three
pins are connected?
thanks and 73,
Paul
DO NOT CONNECT RS-232 to your KIO2 without opening all unused (by RS-232)
pins. ONly Sig Ground, TX and RX go from computer to K2. All other lines on
the KIO2 are not RS-232 and can't tolerate the +- 15V the computer will
supply.
