3. Hold down the R and ACS keys, and then cycle the power to the generator.
The following message appears on the front panel LCD.
4. Release the R and ACS keys.
The generator is placed in Hot-Plug Format mode. This loads the Format knob list with
formats supported by the connected HDMI display (hot-plug formats read via EDID
structure of attached display).
Note: To toggle between the factory default and hot-plug Format knob lists, press and
release the R and ACS keys. Using the factory default Format knob list will disable the
generator’s ability to automatically select the appropriate output signal protocol (HDMI
or DVI) as performed in step 6. In this case, you must manually select the proper TMDS
output signal via Toggle DVI/HDMI key operation (R and G keys).
5. Hold down the Step , G , and B keys while starting the genertor, until Status display
appears on the LCD.
6. Release the Step , G , and B keys to enable status display on the generator (see
example below).
The format status on the LCD will indicate whether the unit is outputting HDMI or DVI
signal protocol from the Tx connector. An “H” in the format status (H8C in the example
above) indicates HDMI output; a “D” in the format status indicates DVI output.
Note: With the compliant Hot-plug Formats mode active and a hot-plug detected, the
generator automatically selects the appropriate TMDS output signal protocol (HDMI or
DVI) for the attached display (via EDID read).
7. If the output signal protocol is DVI, toggle to HDMI protocol by holding down the R key,
then pressing and releasing the G key.
The format status changes to “H” (from “D”) on the LCD.
