[Elecraft] K2 USB to 9 Pin Cable (info)

[Harry Yingst]

 To Clarify this information
-
The color codes are from the wires on the FTDI USB Cable (USB-RS232-WE-1800-BT-0.0)
-
The only wires that will be connected are the
Yellow Wire that will be connected to Pin 2 of the Male 9 pin connector
Orange Wite that will be connected to Pin 3 of the Male 9 pin connector
Black Wire that will be connected to Pin 5 of the Male 9 pin connector
-
The Green Wire on the USB cable is the RTS Line
The Brown Wire on the USB cable is the CTS line
The Green and Brown Wires should be connected to each other and nothing else.-
The Red wire is unused 
-
This should clear up any confusion

 
 I'm passing this info along for those who may have a K2 and find this useful.

FTDI makes a USB to RS-232 Cable Part Number: USB-RS232-WE-1800-BT-0.0
The cable has a USB plug on one end and is terminated in wires on the other end.
