Hi Marty,
I am thinking you left out the word "not" from your reply where you say "will respond". I think you meant "will NOT respond". If I'm wrong, I apologize. My experience with control of Legacy Powermasters with Cab3 has been that the Halt button doesn't work with them set up on Cab3 as TR's.
