Preston Wireless FF Unit to Start/Stop Red

[Jamie Metzger]

Anyone have any ideas on how to use the run button on the Preston remote to start/stop the red? We have tried both 12v AUX ports and tried changing the GPIO settings to IN-High and Out-Low. I read this somewhere else, explaining that the first pulse is set to high, and the second pulse is set to low.
No luck

please respond ASAP. Thank you
Jamie

Assuming your camera control cable is wired up correctly then the top GPIO port should be configured correctly with the default firmware settings.
