4X4 DVI DL KVM MATRIX CONFIGURATION
AUTOMATIC LINK SELECTION / DUAL LINK ONLY MODE
The 4x4 DVI DL Matrix has the ability to run both Single Link and Dual Link DVI sources.
There is a feature that will either automatically select the link mode, or lock the unit in Dual
Link mode. By default, Dip Switch 3 is in the OFF position (Automatic Link Selection).
Turning Dip Switch 3 to the ON position will lock the unit in Dual Link mode and will only
allow Dual Link signals to pass properly.
PRE-EMPHASIS
Pre-Emphasis is used to help extend a signal travel over a distance of cable. When a DVI
cable connected to a display is over a long cable, it is recommended that Pre-Emphasis
be enabled. Pre-emphasis is enabled by default on all display outputs. For short
cables, disable pre-emphasis on each output by turing it’s corresponding Dip Switch to
the ON position. If any type of extension device, such as a DVI CAT5 Extreme, is used
pre-emphasis must be disabled for proper operation.
