Wiring the power connector

CWhen you are connecting the power supply, voltage polarity is extremely important. Applying power with incorrect voltage polarity could damage

the power supply and the equalizer. Identify the negative lead by the ridges on the side of the cord (see the illustration above).

CDo not tin the stripped power supply leads before installing the captive screw connector. Tinned wires are not as secure in the captive screw connectors and could be pulled out.

WThe two power cord wires must be kept separate while the power supply is plugged in. Remove power before continuing.

To verify the polarity before connection, plug in the power supply with no load and check the output with a voltmeter.

Enabling the DDC Buffer

The DDC clock and data lines by default are routed straight through to the output, bypassing the DDC buffer.

However, if you experience any of the following image problems, changing this setting to engage the DDC buffer should correct them.

•The image cuts in and out, or cuts out completely, after a period of time.

•The image is clear at first, then displays snow (HDCP error).

•No image appears.

•Incorrect color space selection (purple or blue tint)

•Corrupted EDID data (The computer or source cannot read the EDID of the connected display correctly due to a long cable run.)

To enable the buffer,

1. Using an Extron Tweeker or other small Philips screwdriver, remove the seven screws (three on each side and one on top) that hold the top cover onto the unit.

2. Remove the two jack screws on either side of the DVI input connector on the front panel (see the illustration on the next page).

3. Slide the top cover forward until it clears the input connector, then lift it off the unit.

4. Facing the DVI DL rear panel, locate the two DDC jumpers (J5 and J4) on the two sets of three pins in the lower-right corner of the internal board. By default, these jumpers are on the middle and outside pins, which permits the DDC lines to pass straight through without buffering.
