Bob,
I think I bought a TC2004A-03R board to interface with my TT4.
Have you or anyone in groups.io have the hookup and command settings for this board?
Thanks, Greg

Subject: Re: [TinyTrak] Driving GPIO pins
You set up these commands: (they may not be exact since htis is from memory) but similar:
NODISP on
MSGCOMMAND ON
etc
THen, over the air, you send a message to the devices callsign "!OUT=$FF" where $FF is the state you want for the port bits

Evening all
I have a memory that it is possible to drive a gpio pin in a Tinytrak 4 high or low based on the receipt of an over the air command in an APRS packet. 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.
Thanks and regards
