The Input/Output Guide was put together by Jim and I and tested extensively to make sure that inputs and outputs worked smoothly and were well documented.
The first page outlines how peripherals are attached to the Dobot, and the second page is the Digital Signal guide that shows you how to test inputs and outputs.
Page three is Inputs & Outputs for the Magician V1, and page four is exclusively devoted to the V2.
Page five just gives you a great way to test a handshake module with a voltmeter, and an idea for wiring multiple outputs for one cable.
