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
aInput 1 (RGB) connector — Connect a VGA cable between this port and the VGA output port of the analog video source.
bInput 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.
cAudio input — Connect an unbalanced stereo audio source to this 3.5 mm mini stereo jack for an analog audio input.
NOTE: Audio is not embedded in the HDMI signal; it is transmitted simultaneously and is present on all inputs.
Over DTP RS-232 and IR pass-through
dRS-232 and IR connector — To pass serial or infrared data or control signals on the Over
DTP RJ-45 output, connect the controlling device to the transmitter via the RS-232 and IR
captive screw connector. Connect the device to be controlled to the receiver.
DTP output to receiver
ATTENTION: Do not connect this device to a computer data or telecommunications network.
eDTP RJ-45 connector — Connect the transmitter DTP Out port to the DTP In port on the receiver. Extron
recommends that you terminate both cable ends in accordance with the following specications, at a
minimum:
• TIA/EIA T 568B •CAT 6a, shielded
• 24 AWG, solid conductor
Signal LED — Lights when the unit is outputting a TMDS clock signal on the DTP output.
Link LED — Lights when a valid link is established between the units on the DTP cable.
Remote control
fRemote 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).

DTP T USW 333 • Setup Guide (Continued)
gRemote Tally port — If desired, to remotely identify the currently selected input, plug a locally-constructed device into this 3.5 mm,
4-pole captive screw connector. Connect the power wire for the device into the +V pin and connect the ground wire for the each
indicator into the corresponding tally output pin: 1, 2, or 3.
When an input is selected, by either contact closure or front panel selection, the corresponding tally output pin shorts to ground,
closing the circuit and lighting the connected indicator (LED).
hRemote RS-232 port — Plug a serial RS-232 device into the switching transmitter via this rear
panel 3.5 mm, 3-pole captive screw connector for remote control of the switching transmitter.
Reset button
iReset button — This button initiates two levels of reset. For different reset levels, use an
Extron Tweeker or small screwdriver to press and hold the recessed button either while the
switcher is running or while applying power. See the DTP T USW 333 User Guide, available at www.extron.com, for details.
Power
jPower connector — Connect an IEC power cord between the included 12 VDC
power supply and a 100-240 VAC, 50-60 Hz source. Connect the power supply to
either unit, transmitter or receiver, as shown at right. Use the included tie-wrap to
strap the cord to the captive screw connector.
NOTE: Only one power supply is required. A single power supply connected to
either unit in the pair powers both units. A power supply is included with the
transmitter.
Front panel Configuration port
aConfiguration port — Plug a PC or other controlling device into the switching transmitter via this front
panel mini-USB connector for remote conguration of the switching transmitter.
Operation
Switching inputs
Select the desired input by pressing the associated input button. Observe that the
LED for the selected input lights.
NOTE: The switcher must be in normal (manual) mode (see below).
Selecting the switch mode
In auto-input switching mode, the switcher selects to the highest numbered input
with a sync signal present. Turn auto-input switching mode on and off as follows:
1. Press and hold the Mode (Input 1) button.
2. Press and release the button for the desired mode:
Auto (Input 3) — The Auto Switch LED lights.
Normal (Input 2) — The Auto Switch LED goes off.
3. Release the Mode button.
Locking and unlocking the front panel
(Executive mode)
The switcher has a front panel lock feature that locks the front panel. If you try to make
front panel input selections when the panel is locked, all front panel LEDs ash three
times. Toggle the front panel lock on and off by pushing and holding all three Input
buttons simultaneously for 5 seconds. All front panel LEDs ash three times.
Release the buttons.
Interpreting the Status LEDs
Signal LEDs (1 through 3) —Indicate that the switcher detects horizontal sync
(Signal LED 1) or TMDS clock (Signal LED 2 and Signal LED 3) signals on the associated input.
HDCP LEDs (2 and 3) —Indicate that the corresponding input signal is HDCP encrypted.

LockIt®Lacing Brackets
Use the included LockIt Lacing Brackets to securely fasten both HDMI cables as follows.
1. Plug the HDMI cable into the panel connection.
2. Loosen the HDMI connection mounting screw from the panel enough to allow the LockIt lacing
bracket to be placed over it. The screw does not have to be removed.
3. Place the LockIt lacing bracket on the screw and against the HDMI connector, then tighten the
screw to secure the bracket.
ATTENTION:Do not overtighten the HDMI connector mounting screw. The shield it fastens
to is very thin and can easily be stripped.
4. Loosely place the included tie wrap around the HDMI connector and the LockIt lacing bracket as
shown.
5. While holding the connector securely against the lacing bracket, use pliers or similar tools to
tighten the tie wrap, then remove any excess length.
