Thank God someone posted this diagram!!!! I just bought PMDX 126 board to replace a faulty Sound Logic Combo board. The Sound Logic was pre-labeled with all the location for the limit switches, each axis drive, E-stop, etc, making it easy to work with. Once I got the PMDX 126 I was ready to pull my hair out, as nothing is labeled. In fact there is not even a decent photo diagram of the board in the manual. So having someone create this wiring diagram, even though it is for a router, is very helpful to get things started. Would be nice to have a updated manual from PMDX that is more descriptive with pictures/diagrams, as it makes it a lot easier to understand than reading.
