Step 3: Wiring Ins & Outs

Did you have us create a wiring map for you, generate documentation, and provide you with working config files?  If so, you don’t need to do any of this.  If not, here is enough information to get you started:

There is no right or wrong way to layout the wiring in a console.  This is a guide explaining how we do it…  Decide HOW you are doing this BEFORE you run a single wire.  Super important to figure out what goes where before the first wire gets attached!

First things first: keys.

Card 1 – Swell Keys
Card 2 – Great Keys
Card 3 – Pedals

Card 4 – Pedals


Less than 32 pistons total?  Put them on the left over half of the card with pedal keying.  More than 32?  Start another card with them.

Last thing to “bring in” is the sense wires from the tabs (or drawknobs or both).  Try to figure a logical order.  Try NOT to skip spaces.  If at all humanly possible, make the tab senses one continuous string from beginning to end (we are going to think of the coils the same way shortly).  If there are prepared stops with SAMs installed, wire them in.  If there are locations for prepared stops (and you are wiring to the locations), wire them in.

Now that you have an idea of what is going where, do a reality check to make sure you have enough cards to do what you need to do.

As far as driver cards, the coils are wired in a predictable order (stop one on, stop one off, stop two on, stop two off, etc.).  Each 8 pin connector therefore gets the wiring for two stops.  If you accidentally wire them all backwards (stop one off, stop one on, stop two off, stop two on, etc.) it’s okay – there is a way to switch the bits in software.  Any place you skipped a pin in the sense inputs, skip two pins in the driver card wiring.  It is very important to get the wiring in order where it “lines up with” the input wiring.
