For more information about interface installation, refer to
the appropriate installation guide.
Pre-installation Testing
Before installing the interface into the wall, furniture, or floor
box, test the system as follows to verify that the connections and
settings are correct.
1.
Apply power to the interface. The power/signal LED on
the interface should light to indicate that the interface is
receiving power.
2.
Check all connectors and controls to make sure they are
functioning properly.
Troubleshooting
If the power/signal LED does not light or an installation
component does not function properly, first check the wiring at
both the interface and the power supply, and then ensure that
the power supply is connected to a power source.

Check the computer’s user’s guide or contact Extron to

video to the external video port. Also, many laptops’
screens shut off after the external video port is activated.
