Send Power switch — Set the switch as desired:
OFF (default) — Do not send power. The transmitter must receive power from an optional local power supply.
SEND PWR – Send 48 VDC power across the TP cable to remotely power the transmitter.
NOTE: Remote power to the transmitter is only available if the transmitter is also in the Extron DTP3 series. The
switch should be OFF for any other transmitter type.
Signal LED — Indicates the unit is receiving a valid signal on the DTP3 IN connector.
Link LED — Indicates a valid link is established between the units on the DTP3 cable.
J HDMI Output port (see figure 2 on page 1)— Connect a video display to this HDMI connector.
NOTE: See LockIt™ Lacing Brackets on page 3 to use the bracket to secure the connector to the unit.
K Audio Output port— This 5‑pole, 3.5 mm captive screw connector outputs the transmitted, unamplified, line
level analog audio. Connect an audio device, such as an audio amplifier or powered speakers (see Analog
audio output port on page 4 to wire the connector).
L USB Device ports — The four port hub has female USB Type A connectors; two are HID (keyboard and
USB HID
3
4
mouse only) and two that are USB 2.0 (all USB devices, such as thumb drives and cameras). HID
ports can provide 100mA to power connected peripherals. USB 2.0 ports can provide 500mA. An
external hub can be connected only to a USB 2.0 port and adds to the total system hub count.
M Over DTP3 port — Connect a serial RS‑232 signal to this 3.5 mm, 3‑pole captive screw connector for
RS-232
OVER DTP3
bidirectional RS‑232 communication (see Over DTP3 connector port on page 4 to wire the connector).
N Power connector — Plug an external 12 VDC power supply into this 2‑pole connector (see Power port on page 4).

ATTENTION:
• Do not connect any external power supplies until you have read the Attention notications in the Power
Supply section of the DTP3 T/R 301 User Guide.
• Ne branchez pas de sources d’alimentation externes avant d’avoir lu les mises en garde dans la section «
Power Supply » du DTP3 T/R 301 User Guide.
O Reset button — This button initiates two levels of reset (see the DTP3 T/R 301 User Guide, at www.extron.com).
LockIt™ Lacing Brackets
Use an included LockIt lacing bracket to securely fasten an HDMI cable to each device as follows:
1 Plug the HDMI cable into the panel connection.

222
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.
• Ne serrez pas trop la vis de montage du connecteur HDMI. Le blindage auquel
elle est attachée est très n et peut facilement être dénudé.
4 Loosely place the included tie wrap around the HDMI connector and the LockIt lacing bracket as shown.
5 Hold the connector securely against the lacing bracket, use pliers to tighten the tie wrap, then remove any excess length.
