Connect the HDMI source (for example, a DVD player) to the HDMI IN 2 connector. 3.
5 Acquiring the EDID This is usually done only once, when the machine is being set up in an installation. Once acquired, the EDID is saved in non-volatile memory and further acquisition is not necessary. Initially, the VM-22H operates with the factory default EDID. This lets you connect the power before connecting one of the acceptors or sources.
3. Press and hold the EDID SETUP button to select the desired EDID. The OUT LEDs illuminate in the following cycle: OUT 1, OUT 2, both flash (default) and both illuminate (auto-mix). 4. Release the button when reaching the desired set up. The EDID is now acquired. If you set the machine to acquire the EDID from an output that is not connected, the default EDID is acquired.
