• XTP DTP 24/1000 Non-Plenum 1000 feet (305 meters) spool
• XTP DTP 24P/1000 Plenum 1000 feet (305 meters) spool
• XTP DTP 24 Plug Package of 10
• 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-T568B standard.
• Limit the use of 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 Category 6 or 6a shielded
couplers and punch down connectors.
NOTES: 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 65 feet (20 meters), where cables are straightened, aligned, and
secured in tight bundles.
• Loosely place cables and limit the use of tie wraps or hook-and-loop fasteners.
• Separate twisted pair cables from AC power cables.

TP Cable Recommendations for Ethernet Communication
It is vital that your Ethernet cable be the correct cable type and that it be properly terminated with the correct
pinout. Ethernet links use Category (CAT) 3, 5e, or CAT 6, unshielded twisted pair (UTP) or shielded twisted pair
(STP) cables, terminated with RJ-45 connectors. Ethernet cables are limited to a length of 330 feet (100 meters).
The cable can be terminated as either a patch cable or a crossover cable (see figure 5) and must be properly
terminated for the application:
• Patch (straight-through) cable — Connection of the device to an Ethernet hub, router, or switch that also
hosts a controlling computer.
• Crossover cable — Direct connection between the switcher and a controlling computer.

Pins:
A cable that is wired as TIA/EIA T568A at one
end and T568B at the other (Tx and Rx pairs
reversed) is a "crossover" cable.
A cable wired the same at both ends is called
a "straight-through" cable because no pin/pair
assignments are swapped.

LockIt Lacing Bracket Installation
HDMI signals run at a very high frequency and are especially prone to errors caused by bad video connections,
too many adapters, or excessive cable length. To avoid the loss of an image or jitter, follow these guidelines:
• Limit or avoid the use of adapters.
• Use only cables specifically intended for HDMI or DVI signals.
To securely fasten an HDMI cable to a device:
1. Plug the HDMI cable into the panel connection (see figure 7, 1).

Figure 7. LockIt Lacing Bracket
2. Loosen the HDMI connection mounting screw from the panel enough to allow the LockIt lacing bracket to be
placed over it (2). 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 (3).
ATTENTION:
• Do not overtighten the HDMI connector mounting screw. The shield to which it fastens is very thin
and can easily be stripped.
• Ne serrez pas trop la vis de montage du connecteur HDMI. Le blindage auquel elle est attachée
est très fin et peut facilement être dénudé.
4. Loosely place the included tie wrap around the HDMI connector and the LockIt lacing bracket (4).
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 (5).

Figure 8. DTP3 T 203 Front Panel
APower LED — Lights green when the unit is receiving power and operational.
BReset button — This recessed button initiates three levels of reset on the DTP3 T 203. To initiate the different
reset levels, use a pointed object such as a small Phillips screwdriver or stylus to press and hold the button
while the switcher is running or while it is being powered up (see Resetting on page 15 for details).
NOTE: The switcher can also be reset to its factory default settings using SIS commands (see Resets on
page 39) or PCS (see the DTP3 T 203 Help File).
CAuto Switch LED — Lights green when auto-input switching is enabled (see Auto-input Switching on
page 13 for procedure to set up automatic input selection).
DConfiguration port — Connect a USB-C cable to a computer to configure the device and update the
firmware via PCS, SIS commands, or internal web pages. To enter SIS commands, use a secure
communication utility that supports Secure Shell (SSH). Enter 203.0.113.22 for the IP address where
requested on port 22023. The IP address cannot be changed.
EInput selection buttons and LEDs — Press one of these buttons to select an input to switch to the output.
The LED at the right of each button lights when the corresponding input is selected. If auto-input switching is
in effect, these buttons are disabled, but the LEDs continue to light to indicate the selected input. If the
switcher has been reset prior to powering down, the default input selected is input 1.
FSignal status LEDs
• Inputs — Each input has a corresponding numbered SIGNAL LED which lights when a source is
connected to the input connector and TMDS clock activity is detected.
NOTE: If the source device connected to the selected input is HDCP encrypted (requires HDCP
authentication), the corresponding signal LED may not light unless HDCP has been authenticated.
• Outputs — Lights when an active sink (output) device is connected to the HDMI output.

DTP3 T 203 • Operation 12
GHDCP status LEDs (see figure 8 on page 11)
• Inputs — Each input has a corresponding numbered HDCP LED. If the connected source requires HDCP,
the corresponding LED lights when authentication is successful.
NOTE: HDCP is authenticated on each input regardless of the currently selected source.
• Outputs — Lights if the currently selected input requires HDCP and the connected output device has
been successfully authenticated.
NOTE: HDCP is re-authenticated on the output whenever a new input is selected.
HUSB-C power delivery LED — Lights green when the unit is powering a connected USB-C source.
Operation
After the switcher and the connected devices are powered up, the system is fully operational. If any problems are
encountered, ensure all cables are routed and connected properly.
NOTE: The transmitter can be configured via PCS (see the DTP3 T 203 Help File) and SIS commands (see
SIS Configuration and Control on page 26).
Powering on the Switcher
To power on the unit:
1. Connect all input and output devices to the rear panel connectors on the switcher (see Rear Panel Features
on page 4 for rear panel connections).
2. Power on the display.
3. Power on the DTP3 T 203 unit. Plug a standard IEC power cord into the power port on the switcher rear
panel. During the boot process:
a. The unit performs a self-test, during which the front AUTO SWITCH, INPUTS, SIGNAL, and HDCP LEDs
each blink once in sequence from left to right.
b. The power LED blinks for approximately 45 seconds. During this time, the switcher reads the available
EDID information from the connected output device and writes it to memory on each input. When power
is removed, these settings remain in the memory and are in effect when power is reapplied.
c. At the end of the boot process, the power LED turns off, and the LED for the most recently input lights.
4. Power on the input devices.
Selecting an Input
To switch (tie) an input to the output, you have the following options:
• Front panel buttons — Press the desired input button on the front panel (ensure
auto-input switching is not enabled). The LED corresponding to the selected input button lights.
• The appropriate front panel input LED lights to indicate the selected input. The LED remains lit until a new
input is selected.
• Only one input can be switched to the output at a time.
NOTE: Buttons are disabled in auto-switch mode, but LEDs still indicate the selected input.
• Contact closure — Plug one of the provided 4-pole captive screw connectors into the rear panel CONTACT
port. If a push-button contact closure device is attached to a CONTACT port, press the button that is
connected to the slot that corresponds to the desired input (see Contact Closure Wiring on page 9 for more
information).
NOTE: If an input pin is latched permanently to the ground pin, input switching by any other method is
disabled while those pins are connected.
