2. Logic supply dc return is connected to all odd pins on the signal side.
3. Signal pin is pulled up to +Vcc when not asserted, down to dc return when asserted.
4. Power-side terminals are polarized for dc applications, and non-polarized for ac applications.
5. The backplane is shipped with a jumper configuration to supply the logic voltage through pin 49 of the edge connector.
