4 VS-88DTP - Overview
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 (1.65Gbps per graphic channel)
•8 DVI-D inputs on DVI-I connectors
•8 DGKat twisted pair outputs on RJ-45 connectors
•HDTV compatibility (no HDCP compliance)
•DGKat™ Signal Integration that converts TMDS as well as control and
communication to signals that run over twisted pair cables. Kramer strongly
recommends using Kramer DGKat™ cables designed specifically for
optimum performance
•Kramer Equalization & re-Klocking™ Technology that rebuilds the digital
signal integrity to travel longer distances
•I-EDIDPro™ Kramer Intelligent EDID Processing™, an intelligent EDID
handling & processing algorithm that ensures Plug and Play operation for
DVI systems
•A system range of up to 30m (98ft) at 1080p on shielded BC-DGKat524
cable; up to 70m (230ft) at 1080p on shielded BC-DGKat623 cable; up to
90m (295ft) at 1080p on shielded BC-DGKat7a23 cable
•Flexible control options including: front panel, IR remote (included), RS-232
(K-Router™ Windows®-based software is included), RS-485, Ethernet
(Windows®-based Ethernet Configuration Manager & Virtual Serial Port
Manager included)
•Output disconnect for each output
•Front panel lockout to prevent tampering with the front panel buttons

RS-485 port on the rear panel of the VS-88DTP
•Connect the G pin on the RS-485 port of the PC to the G pin on the RS-485
port on the rear panel of the VS-88DTP
5.2.1 Setting the RS-485 Machine Number
When several VS-88DTP units are connected, the machine number determines
the unique identity of the VS-88DTP on the bus (see Figure 6).
Note:
•When using a stand-alone VS-88DTP unit, set the machine number to 1
(factory default)
•When connecting more than one VS-88DTP, set the first machine
(connected via RS-232) to be machine number 1. The other
VS-88DTP units must each be set to a unique machine number between 2
and 16
The machine number on the VS-88DTP is set using the DIP-switches on the rear
panel.
To set the RS-485 machine number using the DIP-switches:
Figure 4illustrates the factory default MACH # DIP-switch settings.
