3 Overview The VS−88DTP is a high−performance matrix switcher for DVI signals. The unit accepts up to eight DVI inputs, reclocks and equalizes the signals, and routes to any or all DGKat™ twisted pair outputs simultaneously for connection to compatible TP receivers, for example, the PT-572HDCP+ or TP-574. More specifically, the VS-88DTP features: • A maximum data rate of 4.95Gbps (1.
• A worldwide power supply of 100-240V AC • A standard 19” rack mount size of 1U with included rack “ears” Note: The VS-88DTP requires STP (shielded twisted pair) cable. For optimum range and performance, use Kramer's BC-DGKat524, BC-DGKat623 or BC-DGKat7a23 cables. The transmission range depends on the signal resolution, graphics card and display used. The distance using non-Kramer CAT 5, CAT 6, and CAT 7 cables may not reach these ranges.
