once between this connector and the source or destination.

• The length and preparation of exposed wires is important (see the second and

Amber — The unit is receiving power, either locally or remotely (on the DTP cable).

Green — The unit is receiving an active HDMI input, either on the HDMI input if a

transmitter, or transmitted on the DTP cable if a receiver.

Green — The unit is receiving power locally.

After the transmitter, the receiver, and their connected devices are powered up, the system is

fully operational. If any problems are encountered, ensure all cables are routed and

connected properly.

NOTE: Ensure that the video source and display selected for the DDC are properly

connected to the transmitter and receiver pair, and that the transmitter, the receiver,

and the display have power applied before power is applied to the video source.

If the other devices are not turned on before the video source, the image may not

appear.
