IN1804 Seamless Scaling Switchers • Introduction 2
Integrated Digital Twisted Pair Extension
The DTP2 inputs and outputs are proprietary signals that are created within any of
the Extron DTP Extender systems and transmitted over a single shielded twisted pair
(STP) cable. The IN1804 accepts DTP inputs from transmitting devices such as the
DTP T USW 333.
NOTE: Extron XTP DTP 24 shielded twisted pair cable is strongly recommended for
optimal performance.
• The IN1804 DI and IN1804 DI/DO can receive signals from remote DTP or DTP2
transmitters at a conference table, lectern, or wall.
• The IN1804 DO and IN1804 DI/DO can transmit to a DTP or DTP2 receiver or directly to
an HDBaseT enabled display device.
All twisted pair models can be integrated into an XTP II matrix switcher system. Additionally,
they can send power to selected DTP or DTP2 endpoints over the same shielded CATx
cable, streamlining system design and installation.
DTP transmitters and receivers are available in compact, low-profile enclosures, plus
decorator-style wallplate and floorbox versions to suit the installation requirements of a
specific application.
RS-232 and IR signal insertion
Bidirectional RS-232 and IR signals can be inserted from a control system and transmitted
over the single shielded CATx cable together with the video and audio, enabling control of
a source or display. The DTP2/XTP/HDBT output on IN1804 DO and IN1804 DI/DO can
be configured for compatibility with HDBaseT-enabled displays to send digital video and
embedded audio, plus bidirectional RS-232 and IR signals up to 330 feet (100 meters) over
a shielded CATx cable.
Matrix switcher integration
In addition to supporting DTP endpoints, the IN1804 twisted pair models can be integrated
into an XTP CrossPoint matrix switcher system. This enables facility-wide AV system
applications with a centralized AV signal distribution infrastructure, as well as several

AAC Power connector — Connect a standard IEC power cord (provided) from a
100 to 240 VAC, 50-60 Hz power source to this connector. The front panel button
LED for the selected input (see figure 16, B) on page 21) blinks for approximately
30 seconds. When the unit is ready for operation, the input selection LED lights steadily.
If auto-input switching has been enabled, the Auto SW LED lights also (see Auto
Switch on the OSD Advanced submenu on page 39).
BDisplayPort input connector (input 1) — Connect a DisplayPort source to this
female DP connector.
CHDMI input connectors — Connect HDMI video sources to these female HDMI
connectors. (The standard and DO models have three HDMI input connectors while the
DI and DI/DO models have two.)
TIP: Use Extron HDMI LockIt Lacing Brackets to secure HDMI cables to the
device (see HDMI Connections on page 17).
DOver TP IR pass-through port for input (IN1804 DI and IN1804 DI/DO only) —
To transmit and receive infrared data to and from a source
connected to the DTP2 transmitter or XTP matrix switcher, connect a
control device (such as an Extron IPCP Pro Control Processor) to
this 3-pole IR Over TP captive screw port (see the illustration at
right).
NOTE: RS-232 communication can also be sent to the far end
of the twisted pair connection, but it must be done through
RS-232 insertion via Ethernet. A signal sent to an IN1804
LAN port can be routed to the RS-232 port of any connected
twisted pair device (see Ethernet to RS-232 Insertion on
page 44).

ATTENTION:
• Do not connect these ports to a computer or telecommunications network.
• Ne connectez pas ces ports à des données informatiques ou à un réseau de
télécommunications.
• DTP2 remote power is intended for indoor use only. No part of the network that
uses DTP2 remote power should be routed outdoors.
• L’alimentation DTP2 à distance est destiné à une utilisation en intérieur
seulement. Aucune partie du réseau qui utilise l’alimentation DTP2 à distance
ne peut être routée en extérieur.
NOTE: Depending on the connected transmitter, the DTP2 input can travel up to
330 feet (100 meters) without loss of signal integrity.
FDTP2/XTP/HDBT output connector (output 1A, IN1804 DO and IN1804 DI/DO
only) — The DTP output signal can travel up to 330 feet (100 meters) without a loss of
signal integrity.
Connect a DTP or DTP2 receiver, an XTP matrix, or an HDBaseT-compatible device to
this twisted pair OUT connector. For cable wiring and recommendations, see Twisted
Pair Recommendations for DTP2, XTP, and HDBaseT Communication.
The output 1A connector has the following LEDs:
• Signal LED — Lights when the switcher is sending a signal.
• Link LED — Lights when a valid link is established.
