Spark EXT pinout

Hello. I am creating a module for the back of my camera and would like to know the pinout for the EXT port. 

Here’s what’s in the user manual. 

Thanks! I am curious of the GPO functional differences. Might have to wait for the device and figure it out on my own.

Right now I think only R/S is enabled in the camera, that is what it appears to be anyway in my camera.
