I thought I'd un-bury these questions from the AC tread, I don't know if it will get answered otherwise:

Input Question:

Inputs have three leads: low ref, high ref, and sensed right?

Is the low ref side the same as ground?

Can I leave sensor low reference disconnected from the board and connect it to gnd somewhere else if I plan to use that path as a return path for current from a servo motor as well as sensor low reference?

Will that affect sensor reading at the middle terminal?

See http://www.mp3car.com/vbulletin/1141485-post8.html for context.

Output question:

Can I tie the + side of several digital outputs together, I would assume it would be fine, and that the + side of the outputs (the non transistor side) comes from one place anyway, but I thought I'd ask.

Then again, it's not like I can get these things to work on my computers anyway

all three wires should be run back to teh fusion brain. we sell 3 pin extensions for this.

you can tie together the + side. ground is switched.

bad news for me. how much current can the low side take?

Edit: Enough for a servo motor's drive current?

There, I bought some 3 pin extensions, are you happy now?

I guess I'll have to hack the servo and seperate the two circuits, pre brain....thanks for the info.
