Wiring for Input Selection by Contact Closure
The Contact port provides an alternative method of input selection. Connect a
push-button contact closure device to this port to switch the desired input to the output
as follows:
1. Plug one of the provided 5-pole connectors into the Contact port. On the SW6 and
SW8 HDMI, plug connectors into either or both parts of the dual Contact port.
2. Insert the signal wire of the contact closure device into the slot representing the
desired input number on the SW HDMI Contact port.
Pin 1 = Input 1 contact
Pin 2 = Input 2 contact
Pin 3 = Input 3 contact (SW4, SW6, and SW8 HDMI only)
Pin 4 = Input 4 contact (SW4, SW6, and SW8 HDMI only)
Pin 5 (G) = Contact ground
Pin 6 = Input 5 contact (SW6 and SW8 HDMI only)
Pin 7 = Input 6 contact (SW6 and SW8 HDMI only)
Pin 8 = Input 7 contact (SW8 HDMI only)
Pin 9 = Input 8 contact (SW8 HDMI only)
Pin 10 (G) = Contact ground (SW6 and SW8 HDMI only)
3. Insert the ground wire of the contact device into the G slot of the Contact port (pin 5
or 10).
After wiring the connector, press the button on the contact device to switch the
connected input to the output.
