[Elecraft] KPA500 AUX Button & Serial cabling

[Eric Swartz WA6HHQ - Elecraft]

Hi Bill,

The AUX button is for future expansion. Not determined at this time.

The computer RS-232 is for firmware downloads and remote control, if desired. It does not need to be connected for regular AMP operation. You do not daisy chain the KPA500 at all. 

The second RS-232 is for monitoring Kenwood band info, since those rigs do not have dedicated band data outputs.

73,
Eric
