[Elecraft] AUXBUS Troubleshooting

[Jack Brindle]

Karin;

Please elaborate on exactly what you are trying to do and what you are seeing.

The AUXBUS data stream is not a part o the CAT system, and is used only internally for
communications between our modules. If you are seeing CAT issues, then I strongly
suspect something else is going on. One thing to remember with the K2 is that the
AUX I/O connector carries more than just RS-232 signals, and when connecting the
radio to the computer these non-RS-232 signals MUST NOT connect to the computer
DE-9 connector at all, or very bad things will happen.
