This module plugs into a driver socket to redirect the signals to the terminal block. The shift registers have the power to driver the opto couplers. They should be run with the 5V Vcc jumper installed.
Some external drivers require the common to be Gnd, some require 5V and most don't care. The jumper allows you to select.
