Product Overview
Package Contents
The DigitaLinx DL-HD70 HDBaseT extender set transmits HDMI (1080p, 4K (UHD/HDR) and 3D) including HDCP 2.2,
bidireconal IR, and RS232 up to 70 meters away using a single Category 6 twisted pair cable.
Built-in surge protecon and diagnosc LEDs ensure hassle-free and robust installaons. Flexible power design allows the
units to be powered at either the TX or RX end, and only one power supply is required. The 18 volt power supply is secured
with a screw-on connector to prevent the power from being accidentally disconnected.
The DL-HD70 is sold only as a set. The individual transmier and receiver are not compable with other HDBaseT devices
due to proprietary PoE circuitry.

Installaon Instrucons
Quick Start
1. Connect video source to transmier HDMI IN
2. Connect display technology to receiver HDMI OUT
3. Connect transmier and receiver together with a shielded Category 6 cable
4. Connect control (oponal)
5. Apply power to either transmier OR receiver to power enre circuit
Connect an HDMI source device to the HDMI input on the DL-HD70 transmier labeled HDMI IN using an HDMI
cable that is less than or equal to 5 meters in total length. For HDMI source devices that are further away, an
acve HDMI cable may be required to complete the connecon.
Connecng a Video Source
HDMI Input (Transmier)
Connecng a Display
HDMI Output (Receiver)
Connect the display to the HDMI output on the DL-HD70 receiver labeled HDMI OUT using an HDMI cable that
is less than or equal to 5 meters in length. It is recommended to keep the DL-HD70 receiver near the display
input as it is not recommended that an acve HDMI cable be used on the HDMI output on the DL-HD70 receiver.

Connect one end of a Category cable to the DL-HD70 transmier labeled TWISTED PAIR, then connect the other
end of the Category cable to the DL-HD70 receiver labeled TWISTED PAIR
HDBaseT Connecon
Twisted Pair Wiring
Use TIA/EIA-568B wiring for Category 6
connecon between send and receive
units.
To ensure proper performance of the DL-HD70, it is recommended that you use solid core, shielded Category 6 F/UTP
cabling at a minimum. Category 5e F/UTP may perform well up to a certain length but may not support power over
HDBaseT reliably longer distances.
For opmized performance use the following Liberty Wire and Cable branded cabling;
Category 6 plenum; 24-4P-P-L6SH
Category 6A plenum; 24-4P-P-L6ASH
Category 6 NON-plenum; 24-4P-L6SH
Category 6A NON -plenum; 24-4P-L6ASH
When using shielded category cabling ALWAYS...
....use shielded connectors
....properly ground the category cable
Connecng RS232 Control
RS232 Wiring
Connect the controller or device RX signal
to TX on the DL-HD70 extender. Connect
the controller or device TX signal to RX on
the DL-HD70 extender.
RS232 or serial control signals can be transmied through the DL-HD70 using the RS232 connecon ports on he
DL-HD70 transmier and receiver.

Connecng IR Control
Source Device Control using IR
Aach the IR emier to the IR receiver of the source device, insert the TS 3.5 mm plug of the emier to the IR
OUT port of the DL-HD70 transmier. Insert the TS 3.5 mm plug of the IR receiver (eye) to the IR IN port of the
DL-HD70 receiver. Point the source device IR remote at the display locaon where the IR receiver is located, IR
signals will now travel through HDBaseT to the DL-HD70 transmier side where the IR emier is aached to the
source device.
Aach the IR emier to the IR receiver of the display device, insert the TS 3.5 mm plug of the emier to the
IR OUT port of the DL-HD70 receiver. Insert the TS 3.5 mm plug of the IR receiver (eye) to the IR IN port of the
DL-HD70 transmier. Point the source device IR remote at the source device locaon where the IR receiver
is located, IR signals will now travel through HDBaseT to the DL-HD70 receiver side where the IR emier is
aached to the display device.
The DL-HD70 is capable of transming bi-direconal IR signals through the HDBaseT circuit. The DL-HD70
comes with 2 IR receivers (eye) and 2 IR emiers (ashers) so you can control devices from either end of the
extender circuit.
Remote Display using IR
To pass 3rd party IR system signals through the DL-HD70, such as a control system, connect the TS connector
of the IR-AC coupling cable (provided) to the IR output port of the control system and connect the TRS connec-
tor of the IR-AC cable to the IR IN to either transmier or receiver of the DL-HD70.
Source / Display Control from Control System
Passing IR Signals:
The DL-HD70 is capable of passing IR signals between 33 and 55 KHz. To prevent damage to
any of the electronics, the extenders should be powered o while inserng or removing any IR
components. Inserng an IR transmier into the IR IN port may damage the IR circuit for that
extender.
