appears on the generator’s display as shown below.
b. Choose the HDMI-H item by pressing the adjacent soft key. The interface is
activated and the port outputs the currently selected image and format.
c. Alternatively, to activate the interface through the command line interface, enter the
following commands:
XVSI 4 // Selects the HDMI-H interface
ALLU // Applies the interface setting to the generator
