Input side is connected to the ActiveWire bus connector so that it can be easily plugged in to the ActiveWire USB board.

Output is optically isolated bi-polar transistor.  See spec of the chip here.
In above table, 'C#' corresponds to Collector, 'E#' corresponds to Emitter.




Following example demonstrates controling RC servo motor.
Please refer to the wiring diagram below.

ActiveWire Optoisolator board Example

Please select Device# at first.
Device# is the number sequentially assigned to each board by Windows operating system.
If you have only 1 board plugged into your system, Device# is 0.
If you have 2 boards plugged into your system, the first board is 0, the another is 1.

Click in the box below, type in a number, then click Open.
