User Guide Owner's manual
The 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 TP cable that carries DVI video.
TP Cable Advantages
Twisted pair cable is much smaller, lighter, more flexible, and less expensive than coaxial or 
DVI cable. These transmitter and receiver twisted pair (TP) products make cable runs simpler 
and less cumbersome. Termination of the cable with RJ-45 connectors is simple, quick, and 
economical.
NOTE: Do not use Extron UTP23SF-4 Enhanced Skew-Free
™
 AV UTP cable or 
STP201 cable to link the transmitter and receiver. The DTP DVI 301 Tx/Rx does 
not work properly with these cables.
Control Communications
The RS-232 and IR communications are via a passive pass-through only; the transmitter and 
receiver do not generate or respond to these signals.
Features
Transmits single link DVI signals over a singleCAT 5e, CAT 6, or CAT 6a cable — 
Standard twisted pair cables provide an economical, easily installed cable solution.
Transmits analog audio signals over a separate, optional CAT 5e or CAT 6 cable — 
Standard twisted pair cables provide an economical, easily installed cable solution.
Long distance transmission — Up to 100 feet (330 m)
Supports Display Data Channel (DDC) transmission — The transmitter and receiver pair 
fully supports long distance transmission of the DDC signals.
Control communications pass-through — Bidirectional RS-232 and IR control signals 
can be transmitted alongside the DVI signal, so that the remote display can be controlled 
without the need for additional cabling.
Supports CEC signal transmission with the appropriate DVI-to-HDMI adapters
1-inch high, quarter rack width, metal enclosures — With low profile enclosures, the 
transmitter and receiver can be discreetly installed in locations such as behind a plasma or 
LCD flat-panel display.
External 100 VAC to 240 VAC, 50-60 Hz, international power supply 
(part number 70-775-01) — Included with the transmitter
Remote powering of transmitter or receiver — Only one power supply is necessary to 
power both devices.
