System operation
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.
N
Ensure that the video source and display selected for the
DDC are properly connected to the transmitter/receiver
pair, and that the transmitter, the receiver, and the
display have power applied before power is applied to
the video source. If all other devices are not turned on
before the video source, the image may not appear.
Technical Points for Digital Video and Content
Protection Encryption
• Digital Visual Interface (DVI) is a digital video format
that was created by the computer industry in 1999.
• High Defi nition Multimedia Interface (HDMI ™ ) is a
multimedia format that was created by the consumer
video industry in 2003.

The HDMI format is built onto the DVI format,
adding digital audio and control while reducing the
size of the connector.

The HDMI format is likely to replace the DVI format
in the near future.

With passive adapters, the HDMI format is backward
compatible with the DVI format.
• With Extron adapters and/or cables, the DVI 201 fully
supports either format, regardless of the connector
type on the video source and display. See appendix A,
Reference Information , for part numbers.
