Disabling EDID Minder
Some applications require that the distribution amplifier does not automatically
read the EDID from one or more specific outputs. In those cases, the EDID Minder
feature can be disabled so those specific outputs are ignored during the automatic
scanning process:
1.
Remove and keep the screws holding the cover to the base. For the DVI DA4,
there are three screws along the rear edge of the top and two screws on each
side. For the DVI DA6 and DVI DA8, there are four screws along the rear edge
of the top and three screws along each side. Set aside the top.
2.
Check the part number of the printed circuit board (outlined in yellow in the
figures below). The boards must have a part number of 20-1496-01LF and
higher for the DVI DA4 or 20-1497-01LF or 20-1497-01LF and higher for the
DVI DA6 or DVI DA8.
N If the board's part number is lower than these values, you cannot deactivate the
EDID Minder on your model. Replace the cover as described in step 5.
3.
Locate the DIP switches. There is a single bank of four switches for the
DVI DA4 (outlined in red in the figure below). Each switch regulates the
correspondingly numbered output (1-4).
There are two banks of four switches for the DVI DA6 (outlined in red in the
figure below) and the DVI DA8. In the first bank of DIP switches, each switch
regulates the correspondingly numbered output (1-4). In the second bank of
DIP switches, switches 1 and 2 correspond to ouputs 5 and 6 for the DVI DA6;
switches 1-4 correspond to ouputs 5-8 for the DVI DA8.
4.
By default the switches are in the off/down position,
allowing the EDID information to be read from the
corresponding output. To deactivate EDID Minder for one
or more outputs, move the switch for that output to the on/
up position. In the diagram at right, the unit will read EDID from output 3, but
not from outputs 1, 2, or 4.
5.
Replace the cover, using the screws that were removed in step 1.
