Extron Electronics DVI DL 101 Setup Guide - Manual (Page 2)

Input cable lengths
For the highest transmission rate of 330 MHz (for dual link) or 165 MHz (for single link), the maximum cable length should
be 200 feet (61 m). Longer cables can be used at lower rates.
The DVI DL can operate in dual link mode or single link mode. The table below shows the maximum cable lengths
recommended for each resolution in both modes.
Video Resolution Single Link Mode Dual Link Mode

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 image
problems, changing this setting to engage the DDC buffer should correct
them.
To enable the buffer:
1. Remove the seven screws that hold the top cover onto the unit and the
two jack screws on either side of the front panel DVI input connector.
2. Slide the top cover forward until it clears the input connector, then lift it
off the unit.
3. With the DVI DL rear panel toward you, 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 lets the DDC lines pass straight through without buffering.
4. Lift each jumper off its pins and slide it down onto the inside and middle
pins. (See figure 2 at right.)
5. Replace the top cover onto the unit and slide the cover back until the DVI
input connector protrudes through its slot in the front panel.
6. Replace the two jack screws and the seven Philips
screws that you removed in step 1.
