CONFIGURING THE 4X4 DVI DL MATRIX

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 is used pre-emphasis must be disabled for proper operation.
