Jim, Look at the navigator for this purpose as a USB to RS-232 converter. So, you have the USB cable from the computer to the Navigator (I trust you have loaded the applicable drivers). That enables the RS-232 port on the Navigator to be connected to the K3 - use the 'Y' connector that you got with your SteppIR at the K3, and connect the cable to the Navigator to one side of the Y and the SteppIR controller to the other side of the Y. Mechanical stuff is complete, all the rest is software applications - it should work.
Note, the other part of the Navigator provides an external soundcard function - that has nothing to do with the Navigator USB to RS-232 conversion - keep the two separate in your mind. 73, Don W3FPR On 2/24/2012 8:01 PM, James Meade wrote: > The K3 is connected to the Navigator and the KPA500 via the ACC port > which is a 15 pin D.
