Line Finders from Solenoid Breakout

Hey all,

We were given some advice today on our line-finders, which were working fine at home but failing at the Rally today: Wire the power (individually) to the pins on the solenoid (pneumatic) breakout, which is powered 24V instead of 12V, and thus has less likelihood of dropping the line finder voltage below 10.9 V (where they stop working).

Problem: To do this successfully, we must program LabView to turn them on (while you have to do no such thing if they are wired to the PDB).

Problem compounder: Our main student programmer and both of our programming mentors are in various places in the Caribbean for the week. (Though not together, as that would be somewhat on the strange side of things.)

Anticipated solution: Knowledge of how to turn on the line finders when they are wired to the two-pin connectors on the Solenoid breakout (which I believe goes in slot 8).

So... Could someone point me in the right direction so that we could figure out tomorrow how to get the line finders to turn 'on' in this situation?

Thanks much!

Patrick
