Chip, Look at that cable with "different eyes" only the pin 2 and pin 3 connections carry RS-232 signals - Oh yes, pin 5 is also RS-232 Signal Ground. All other pins are internal K2 signals which are used between the K2 and the KPA100, KAT100, KRC2 and/or the XV series transverters. By design, there is no conflict on these internal K2 signals,
If you observe carefully, you will find that pins 2, 3 and 5 connect only between the K2 and the computer. A single point to point connection - that is NOT a "Y" connection for the RS-232 signals. As an aside, if you are looking at the K2 AUX I/O connector as an RS-232 connector, forget that - it is not - all DB-9 connectors are NOT an RS-232 connector. If you plug a standard computer serial port cable into the K2 AUX I/O connector, you can damage your K2. Use the cable wired as indicated in the KAT100 manual and forget about any additional "splitter" - all will be well. 73, Don W3FPR On 8/8/2012 7:23 AM, Chip Stratton wrote: > I do have a properly wired Rs232 to KIO2 adapter cable which I have been > using for K2 to computer comms.
