About this Guide
This guide describes the Extron DTP T USW 333 switching transmitter. The switcher
outputs a signal to a compatible DTP receiver. This guide describes how to install, operate,
and configure the switcher.
NOTE: In this guide, the DTP T USW 333 is commonly referred to as a “switcher” or a
“switching transmitter.”
About the DTP T USW 333 Switcher
The DTP T USW 333 is a 3 input VGA and HDMI switcher with a DTP transmitter output
(see figure 1). It switches among one analog VGA and two HDMI inputs, including embedded
audio (or DVI video with the appropriate adapters). The switcher converts the selected input,
an optional analog audio input, and bidirectional RS-232 and infrared (IR) control signals
to a proprietary digital signal. It outputs the signal to a compatible DTP DVI 330 Rx or
DTP HDMI 330 Rx receiver. The switcher and receiver extend the usable distance of video,
audio, and control signals up to 330 feet (100 m) over a single twisted pair cable.
The DTP T USW 333 is housed in a half rack width metal enclosure. It can be set on a
tabletop or mounted in a rack, or under or through furniture.
The included external desktop 12 VDC power supply accepts 100 to 240 VAC, 50-60 Hz. A
single power supply connected to either unit can power both units through the TP cable.
DTP T USW 333 • Introduction1
Features
TP Cable
Extron recommends XTP DTP 24 shielded twisted pair (STP) cable for best performance.
Category (CAT) 5e, CAT 6, CAT 6a, or CAT 7 STP or unshielded twisted pair (UTP) cable
is acceptable. Extron recommends at least 24 AWG, solid conductor, STP cable with a
minimum bandwidth of 400 MHz.
NOTE: Do not use Extron UTP23SF-4 Enhanced Skew-Free AV UTP cable or
STP201 cable to link the switching transmitter and receiver. The DTP T USW 333 does
not work properly with these cables.
Twisted pair cable is smaller, lighter, more flexible, and less expensive than coaxial
cable. The DTP 330-enabled products make cable runs simpler and less cumbersome.
Termination of the cable with RJ-45 connectors is simple, quick, and economical.
Control Communications
The RS-232 and IR communications are pass-through only. The switching transmitter and
receiver do not generate or respond to the RS-232 and IR communication signals.
Transmits HDMI or analog video, control, and analog audio up to 330 feet
(100 meters) over a single CATx cable — The DTP T USW 333 provides high reliability
and maximum performance on an economical and easily installed cable infrastructure.
Inputs — Two HDMI, one RGBHV or component video on 15-pin HD, one 3.5 mm stereo
mini jack for audio
Supports computer video to 1920x1200, including HDTV 1080p/60 Deep Color and 2K —
The DTP T USW 333 supports digital signal transmission up to 330 feet over a single
twisted pair cable and maintains superior image quality at the highest resolutions.
Accepts additional analog stereo audio signals — The DTP T USW 333 accepts a
direct analog audio connection from Blu-ray Disc players, laptops, or other devices with
stereo output and digitizes them for simultaneous transmission over the same single twisted
pair cable. A DTP 330 receiver can output balanced and unbalanced audio, allowing
streamlined integration within an AV system.
Bidirectional RS-232 and IR insertion for AV device control — Control and IR signals
can be transmitted alongside the video signal over DTP connections, allowing the remote
device to be controlled without the need for additional cabling. Bidirectional control insertion
eliminates the need for control system wiring to remote devices.
Remote powering of transmitter or receiver — For simplified installation, only one
power supply is necessary to power both devices.
Digital conversion of analog input signals — Analog signals are digitized, ensuring that
a reliable, high quality digital video signal is sent to the output destination.
EDID Minder — Automatically manages EDID communication between connected devices,
ensuring that all sources power up properly and reliably output content for display.
Key Minder — Authenticates and maintains continuous HDCP encryption between input
and output devices, verifying HDCP compliance for quick, reliable switching in professional
AV environments.
Compatible with all DTP HDMI 330 and DTP DVI 330 receivers, and
DTP 330-enabled products — Enables mixing and matching with desktop and wallplate
receivers, as well as other DTP 330-enabled products to meet application requirements.

The DTP T USW 333 is compatible with CAT 5e, 6, 6a, and 7 shielded twisted pair (F/UTP,
SF/UTP, and S/FTP) and unshielded twisted pair (U/UTP) cable.
Cable recommendations
Extron recommends using the following practices to achieve full transmission distances up
to 330 feet (100 m) and reduce transmission errors.
• Use the following Extron XTP DTP 24 SF/UTP cables and DTP 24 connectors for the
best performance:
• XTP DTP 24/1000 Non-Plenum 1000’ (305 m) spool 22-236-03
• XTP DTP 24P/1000 Plenum 1000’ (305 m) spool 22-235-03
• XTP DTP 24 Plug Package of 10 101-005-02
• If not using XTP DTP 24 cable, at a minimum, Extron recommends 24 AWG, solid
conductor, STP cable with a minimum bandwidth of 400 MHz.
• Terminate cables with shielded connectors to the TIA/EIA T 568 B standard.
• Use no more than two pass-through points, which may include patch points, punch
down connectors, couplers, and power injectors. If these pass-through points are
required, use CAT 6 or 6a shielded couplers and punch down connectors.
NOTE: When using TP cable in bundles or conduits, consider the following:
• Do not exceed 40% fill capacity in conduits.
• Do not comb the cable for the first 20 meters, where cables are straightened,
aligned, and secured in tight bundles.
• Loosely place cables and limit the use of tie wraps or Velcro®.
• Separate twisted pair cables from AC power cables.
VGA connector wiring
The 15-pin HD (VGA) universal analog input ports accept RGB (RGBHV, RGBS, RGsB) and
component video. Figure 4 shows the pinouts for each format type on the connector.

NOTES:
• The power supply included with the switching transmitter can normally power both
units.
• If you have removed the ground jumpers (see Disconnecting the Ground on
page 19) because of ground potential differences, one unit of the pair cannot
remotely power the other unit. Each unit requires a local power supply.
Figure 5 shows how to wire the connector. Use the supplied tie-wrap to strap the power
cord to the extended tail of the connector.
Figure 5. Power Connector Wiring
CAUTION: Electric shock hazard —
• The two power cord wires must be kept separate while the power supply is
plugged in. Remove power before wiring.
• The length of exposed wires is critical. The ideal length is 3/16 inch (5 mm).
• If the stripped section of wire is longer than 3/16 inch, the exposed wires may
touch, causing a short circuit.
• If the stripped section of wire is shorter than 3/16 inch, wires can be easily pulled
out even if tightly fastened by the captive screws.
• Do not tin the power supply leads before installing them in the connector. Tinned
wires are not as secure in the connector and could be pulled out.
ATTENTION:
• This product is intended to be supplied by a Listed Power Unit marked “Class 2”
or “LPS,” rated 12 VDC, 1.0 A minimum. Always use a power supply supplied by
or specified by Extron. Use of an unauthorized power supply voids all regulatory
compliance certification and may cause damage to the supply and the end product.
• Unless otherwise stated, the AC/DC adapters are not suitable for use in air handling
spaces or in wall cavities.
• The installation must always be in accordance with the applicable provisions of
National Electrical Code ANSI/NFPA 70, article 75 and the Canadian Electrical
Code part 1, section 16. The power supply shall not be permanently fixed to a
building structure or similar structure.
• Power supply voltage polarity is critical. Incorrect voltage polarity can damage the
power supply and the unit. The ridges on the side of the cord (see figure 5) identify
the power cord negative lead.
To verify the polarity before connection, plug in the power supply with no load and check the
output with a voltmeter.

Front Panel Operations
The following paragraphs detail the power up process and provide sample procedures for
switching inputs, changing between normal and auto-input switching mode, and toggling
executive mode on and off.
Power
Power is automatically applied when the power cord is connected to an AC source. When
AC power is applied, the switcher performs a self-test that blinks the front panel LEDs
during the test. An error-free power up self-test sequence leaves the Auto Switch and Input
LEDs on or off in the same configuration as they were when power was last removed.
If an error occurs during the self-test, the switcher locks up and will not operate. If your
switcher locks up on power-up, call the Extron S3 Sales & Technical Support Hotline.
Plug in all system components and turn on the input devices (such as Blu-Ray players
and computers) and the output devices. Set the input devices to output video using the
operating instructions of that device. Select an input. The image should appear on the
screen. If no image appears, see Troubleshooting — If No Image Appears on the next
page.

SIS commands consist of one or more characters per field. No special characters are
required to begin or end a command character sequence. When a command is valid, the
switcher executes the command and sends a response to the host device. All responses
from the switcher to the host end with a carriage return and a line feed (CR/LF = ]), which
signals the end of the response character string. A string is one or more characters.
Switcher-Initiated Messages
When a local event occurs, such as a front panel operation, loss or restoration of an input
signal, or an error condition, the switcher responds by sending a message to the host. The
switcher-initiated messages are listed below:
The switcher issues the copyright message when it first powers on. Vx.xx is the firmware
version number and 60-nnnn-nn is the part number.
Inn All
]
The switcher also sends the Inn message whenever the selected input is changed. n is the
input number. A 0 in the n field indicates no input is selected.
]
Error responses
When the switcher receives a valid SIS command, it executes the command and sends a
response to the host device. If the switcher is unable to execute the command because the
command is invalid or it contains invalid parameters, the switcher returns an error response
to the host. The error response codes are:
Pauses of 10 seconds or longer between command ASCII characters result in a timeout.
The command operation is aborted with no other indication.

Reference
Information
This section provides procedures for mounting the DTP T USW 333 switching transmitter
and disconnecting the ground between it and a compatible receiver.
• Mounting the Switcher
• Disconnecting the Ground
Mounting the Switcher
ATTENTION:
• Installation and service must be performed by authorized personnel only.
• Avoid ground potential differences between the switching transmitter and receiver
installation sites, which can lead to equipment damage or a missing or unstable
picture. If a potential difference cannot be avoided, remove the ground connection
between the units and locally power both units (see Disconnecting the Ground
on the next page).
The 1-inch high, half rack width DTP T USW 333 switching transmitter can be placed on a
table, mounted in a rack, or mounted under a desk or table.
Tabletop Use
Affix the included rubber feet to the bottom of the unit and place it in any convenient
location.
Mounting kits
Mount the unit using any optional compatible mounting kit listed on the Extron website
(www.extron.com), in accordance with the directions included with the kit. For rack
mounting, see UL Rack-Mounting Guidelines on the next page.
DTP T USW 333 • Reference Information18
UL Rack-Mounting Guidelines
Remove 9 Screws
The following Underwriters Laboratories (UL) requirements pertain to the installation of the
unit into a rack.
• Elevated operating ambient temperature — If installed in a closed or multi-unit rack
assembly, the operating ambient temperature of the rack environment may be greater
than room ambient. Therefore, consider installing the equipment in an environment
compatible with the maximum ambient temperature (TMA = +122 °F, +50 °C) specified
by Extron.
• Reduced air flow — Installation of the equipment in a rack should be such that the
amount of air flow required for safe operation of the equipment is not compromised.
• Mechanical loading — Mounting of the equipment in the rack should be such that a
hazardous condition is not achieved due to uneven mechanical loading.
• Circuit overloading — Consideration should be given to the connection of the
equipment to the supply circuit and the effect that overloading of the circuits might have
on overcurrent protection and supply wiring. Appropriate consideration of equipment
nameplate ratings should be used when addressing this concern.
• Reliable earthing (grounding) — Reliable earthing of rack-mounted equipment
should be maintained. Particular attention should be given to supply connections other
than direct connections to the branch circuit (such as use of power strips).
Disconnecting the Ground
If you cannot resolve a ground potential difference between the switching transmitter and
receiver installation sites (as suggested by a missing or unstable picture), remove the ground
connection between the units as follows:
NOTE: Once you have removed the ground jumpers, the DTP T USW 333 cannot
extend analog audio and one unit cannot remotely power the other. No analog audio
is output and the paired receiver requires its own dedicated power supply.
1. Disconnect any cables and remove the switching transmitter from any rack or other
installation option.
2. Remove and retain the screws (nine screws, three on each side and three on top)
securing the cover to the switching transmitter. Slide the cover forward slightly and lift it
off the unit (see figure 11).
TIP: Be careful not to bend the electrical contact “legs” of the button and LED
assemblies on the circuit board. If the buttons or LEDs are misaligned with the
holes in the cover, it may be difficult to reassemble the switcher.
Figure 11. Opening the Switching Transmitter
DTP T USW 333 • Reference Information19
3. Locate and lift off jumpers JMP1 and JMP2 (see figure 12).
P1
JMP2

Figure 12. Jumper Locations
4. Reinstall the switcher cover, securing it in place with the screws removed in step 2.
5. Reinstall the switcher in the rack or other installation option (see Mounting the
Switcher on page 18).
6. If you are using shielded cable, disconnect the cable shield from the connector at
either end of the cable.
7. See the manual for the applicable receiver, DTP DVI 330 Rx or DTP HDMI 330 Rx,
available on the Extron website (www.extron.com), and remove the ground jumpers in
the receiver.
8. Obtain a second 12 V power supply (one supply is provided with the switching
transmitter and normally powers both units), and locally power both units (see Power
supply wiring on page 7).
