DTP T USW 333 • Setup Guide
This guide provides instructions for an experienced installer to set up and operate the
Extron DTP T USW 333 switching video transmitter. The DTP T USW 333 transmitter switches among
an analog video and two digital (HDMI) video inputs and, paired with a compatible receiver, can
extend the selected signal up to 330 feet (100 m). If the selected input is HDMI, the extended video
signal is HDCP-compliant.
Installation
Step 1 — Mounting
Turn off or disconnect all equipment power sources and mount the transmitter as required.
Step 2 — Making Connections
Inputs
a
Input 1 (RGB) connector
— Connect a VGA cable
between this port and the VGA output port of the analog video
source.
b
Input 2 and 3 (HDMI) connectors
— Connect HDMI cables
between these ports and the HDMI output ports of the digital video
sources.
NOTE:
See the
LockIt
®
Lacing Brackets
on page 3 of this guide to securely fasten the HDMI connectors to the transmitter.
c
Audio input
— Connect an unbalanced stereo audio source to this 3.5 mm mini stereo jack for an analog audio input.

Remote control
f
Remote Contact port
— If desired, for contact closure control, plug a locally-constructed contact closure control device into this
3.5 mm, 4-pole captive screw port. Momentarily short the pin for the desired input (1, 2, or 3) to G to select that input. To force an
input to be always selected, leave the short in place.
NOTES:
•
Contact closure control overrides front panel input selections.
•
For contact closure control, auto-input switching mode must be off (see
Selecting the switch mode
on the next page).
