This connector provides means for eight general-purpose inputs and eight general-purpose outputs. Inputs and
outputs may be configured to accept or provide either +5V or +24V signals. Outputs can be made sourcing with
an IC (U55 to UDN2981) and jumper (E1 and E2) change. E7 controls whether the inputs are pulled up or down
internally. Outputs are rated to 100mA per line.
