Dave (and all).
That RS-232 (XCVR) connector on the back of the KPA500 is to support
Kenwood transceivers.
Yes, you are correct - RS-232 cannot be daisy-chained - it is point to
point only. The only exception is for devices like SteppIR which can
work in "listen-only" mode.

I use this USB/RS232 4-port adapter:

$45 and works great. Since my K3, KPA500 and PowerMaster all use RS232
interfaces, I went ahead and used

By the way, an easy solution to the plugging/unplugging requirement is
