[Elecraft] KPA500 firmware load fails?

[Don Wilhelm]

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.
Multiple receivers can monitor what is going on, but multiple drivers on 
any signal will cause confusion and failure (and possible damage to the 
drivers).
