Connectors
This table shows each connector and the boards they connect to. Note that the connectors on each
board are joined to the same numbered connector on other boards. For example, J4 on the Analog I/O
board connects to J4 on the Mic/Line control surface.
The following pages show each connector in detail, including the labeling and designation on each
pin on either end of the connecting cable.
