The VM-4Hxl initially operates with the default EDID. This means that you can turn
ON the power before connecting any of the acceptors or the source.
You can acquire the EDID by sending the:
•EDID from a selected output to the input (see Section 6.1)
•Default EDID to the input (see Section 6.2)
•Auto EDID to the input (see Section 6.3)
The auto EDID is an adjusted calculation of the EDIDs of all the connected outputs.
6.1 Acquiring the EDID from a Selected Output
To select an EDID from a selected output, do the following:
1. Press the SELECT button, as required, to reach the desired output, which
flashes.
2. Press the READ button.
The EDID of the selected output is stored in the non-volatile memory when
the READ button no longer illuminates as well as the selected output LED.
6.2 Restoring the Default EDID
To restore the default EDID, do the following:
1. Press the SELECT button several times until the OUTPUT LEDs flash
simultaneously.
2. Press the READ button.
The READ button illuminates.
The default EDID is stored in the non-volatile memory when the READ
button no longer illuminates as well as the output LEDs.
