Figure 8. Power Indicators
APower (and signal) LED (front panel) —
Amber — The unit is receiving power, either locally or remotely (on the DTP cable).
Green — The unit is receiving an active DVI input, either on the DVI input if a transmitter, or transmitted on the DTP cable if a receiver.
BPower LED (rear panel) —
Amber — The unit is receiving power remotely (on the DTP cable). Green — The unit is receiving power locally.
CDDC Route switch — This rear panel switch selects either the remote or local DVI display as the DDC reference (for EDID communications).
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.
