[ARC5] Questions for all - More info

[Joel R Roberts]

Thanks Mike. The ARA Receiver is the BCB Receiver I "Stole" on the Bay, 
and it is in the single Receiver Rack. It won't matter which set I am 
using as it will always be the same one. Thanks again....Joel  KB0FPT

Assuming that your rack and receivers are still in original configuration, and you are applying power using the normal rack 28vdc connector, you will need a jumper from pin 6 to pin 1 on that 8-pin rack connector when the *local* control adapter is used on the receiver.
