About this Guide
This guide describes the Extron DTP DVI 230 D family of Digital Visual Interface (DVI) 
Extenders, which consists of the DTP DVI 230 D Tx and DTP DVI 230 D Rx. This guide 
describes how to install, operate, and configure them. 
About the DTP DVI 230 D Extenders
The Extron DTP DVI 230 D extenders are a family of DVI transmitters and receivers (see 
figure 1) which are housed in enclosures that can be mounted in Underwriters Laboratories 
(UL) standard wall boxes with Decora
®
-style face plates. A transmitter and receiver pair 
extends the usable distance of DVI digital video and RS-232 or IR control signals over one 
Category (CAT) 5e, 6, 6a, or 7 unshielded twisted pair (UTP) or shielded twisted pair (STP) 
cable. The DTP DVI 230 D transmitter and receiver also route audio. The video, control, and 
audio (if applicable) signals can be transmitted up to 230 feet (70 m).

Figure 1.  Typical Transmitter and Receiver Application
A DTP DVI 230 D system consists of a transmitter (Tx) and a receiver (Rx). The pair can 
handle a single link of DVI-D digital video and a bidirectional RS-232 or IR link. 
The DTP DVI 230 D transmitter and receiver are sold separately. Each transmitter is shipped 
with a single external desktop 12 VDC power supply that accepts 100 to 240 VAC, 
50-60 Hz input. A single power supply connected to either the transmitter or the receiver 
can power both units through the twisted pair cable that links the units.
