I am totally confused.??
Steven VK2BOS was asking about using GPIO pins using over the air commands.
It appears the thread was hijacked for lcd interfacing?
Steve VK2BOS,
Did you get an answer to your question?
Greg,
You should start a new thread on interfacing "TC2004A-03R board to interface with my TT4".
The information us on Byonics website.
Thus totally different than Steve VK2BOS thread.

I have looked at the manuals and this mailing list but can't find anything. I am looking to drive a relay to switch a repeater on and off at a remote mountain site which is battery powered.? Is my memory more faulty than usual?? Could someone point me to some doco on this.
