About the DTP T HWP 231 D and 331 D Extenders
The Extron DTP T HWP 231 D and 331 D extenders are HDMI transmitters (see figure 1)
which are housed in enclosures that can be mounted in Underwriters Laboratories (UL)
standard wall boxes with Decora
®

receiver extends the usable distance of HDMI digital video and RS-232 or IR control signals
over one shielded twisted pair (STP) cable.

Figure 1. A Typical DTP T HWP 231/331 D Point-to-Point Application
A DTP T HWP 231 D and 331 D system consists of a transmitter (Tx) and a compatible
receiver (Rx). A typical system can handle a single HDMI digital video signal and a
bidirectional RS-232 or IR link. Each purchased 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 a compatible receiver can power both
units through the twisted pair cable that links the units (see Power Supply Wiring on
page 11 for more information).
