Park Brake and Engine Cutoff (Fuel Valves?) and FS2Phidgets

Thanks Matt,
Here are two (large) screen shots.
All of a sudden the Park Brake worked, and I have no clue what I did.

The detail page gives me the creeps.
There are too many buttons (a MCP is more simple to me ;-)
Especially the FS value types box and the Possible values box.

The manual is not clear enought to me what option I have to select.

So what steps do you take to program a switch.
Lets assume I want to make the fuel cut-off switches for ENG1 and ENG2 to work.

I believe these are the offsets:

3590 4 Engine 1 Fuel Valve, 1 = open, 2 = closed. Can write to operate. [FS2002+]
3594 4 Engine 2 Fuel Valve, 1 = open, 2 = closed. Can write to operate. [FS2002+]

How do I enter this into FS2Phidgets detail screen?
