Testing HDCP between HDMI transmitter and DVI receiver
HDCP 1.1-compliant devices must interoperate with HDCP 1.0 compliant devices using
the DVI protocol. Generators with an HDMI transmitter can be used to test HDCP with
devices that have an DVI receiver.
To test HDMI Tx with DVI Rx:
1. Hold down the G and B key while starting the generator put the generator in digital
friendly mode.
Alternatively, enter the following command:
SROP 2
2. Establish a command terminal connection with the generator, using HyperTerminal or
VGM.

The DVI mode setting is saved until you change it.
4. Use an HDMI-to-DVI cable (provided with HDMI generator) to connect the HDMI
transmitter to the DVI receiver.
5. Load the HdcpProd image. This image assumes that both the transmitter and receiver
are using production keys.
The image will indicate if the test passed or failed. If the test fails, see “Troubleshooting
HDCP errors” on page 191.
To change HDMI transmitter from DVI to HDMI mode:
