That cable is the one you use if you want to use computer keying with the DTR pin of the serial port. You will use it if you use the N3FJP macros or the computer keyboard to key the transceiver. You don't use it if you want to key with a straight key or bug. Willis 'Cookie' Cooke K5EWJ

The cable is a serial-to-1/4 jack plug. Here's what is on the N3FJP website regarding this setup: The serial module has been designed to provide a hardware link to the transceiver from your computer's DB-9 serial port using the DTR (pin 4 of the DB-9 connector) lead as the active signal and SGND (pin 5) as reference ground. The parallel module uses pin 17 as the active signal and pin 1 as ground. "Please note that these units replace the STRAIGHT KEY. To function properly, you must turn off the transceiver's automatic keyer and plug the unit into the STRAIGHT KEY socket. Keying is accomplished by the tip and sleeve of the Keying Module plug in the same manner as a straight key would do." I can see on my ICOM 746Pro, I would need to go into the menu setup and change to a Straight Key configuration. But, I'm not sure with the K3, as it has the "Paddle" input and the separate "Key" input. So, in my mind (and I could be wrong) I can leave my paddles plugged in, and also plug in the new cable into the "key" input for the computer. Also, if that's not the case, how do I turn off the K3 internal keyer?
