Using EX3 to record SD 702T
 

I'm shooting as a one man band, using an EX3 and a Sound Devices 702T. I've set it up so the mixer/recorder automatically goes into record mode when I hit record on the EX3. It all worked fine at Abel Cine yesterday. Today, I'm testing it/getting to know both devices, I can't get it to work. I"ve checked every menu setting on both devices, but it still won't work. any suggestions would be greatly appreciated.

(fyi, after a hair pulling hour we determined that the EX1 will NOT auto start the 702T)
