Intelix DIGI-HD-IR2
Installation Manual
Introduction
The Intelix DIGI-HD-IR2 transmits HDMI and IR up to 300’ over two twisted pair
cables, such as Cat 5e or Cat 6. In environments with high electromagnetic
interference (EMI), two shielded twisted pair cables should be used.
Built-in HDshāk® technology provides dynamic HDMI, EDID/DDC and HDCP
mode selection, gauranteeing performance and image quality.
The DIGI-HD-IR2 features electrostatic discharge (ESD) protection circuitry which
safegaurds the HDMI circuit against static electricity and other destructive stray
voltage.
Design with Intelix and Design with Intelligence.
Installation
To install the Intelix DIGI-HD-IR2 baluns, perform the following steps:
1. Turn off power and disconnect the audio/video equipment by following the
manufacturer’s instructions.
2. Make certain that outlets and cross connects to which you will connect the DIGI-
HD-IR2 are configured properly and labeled correctly to identify the point-to-point
circuit.
3. Verify the desired twisted pairs are not being used for other LAN or telephony
equipment.
4. Verify that the source and destination equipment work when directly connected with
HDMI cables. Be sure to test both HDMI cables required for system installation.
5. Connect the DIGI-HD-IR2 send balun to the HDMI output of the video source. Do
not connect the 5V power supply.
6. Connect the DIGI-HD-IR2 send balun to the IR emitter.
7. Connect the DIGI-HD-IR2 receive balun to the HDMI input of the receiving device
at the remote end. Do not connect the 5V power supply.
8. Connect the DIGI-HD-IR2 receive balun to the IR receiver.
9. Complete the connection between the send and receive baluns using two runs of
twisted pair cable. Ensure the cable conforms to EIA 568B crimp standards and
there are no split pairs or taps.
10. Connect the 5V power supply to the DIGI-HD-IR2 receive balun.
Caution: Do not attempt to disassemble or alter the balun housin
g
. There are no
user-serviceable parts inside the unit. Doing so will void your warranty.
Caution: Do not connect the balun to a telecommunication outlet wired to
unrelated equipment. Doin

11. Connect the 5V power supply to the DIGI-HD-IR2 receive balun Power-on the
video equipment.
12. Verify picture quality.
13. If necessary, adjust the dip switches on the send and receive baluns to select modes
of operation.
Note: Dip switches are located under the cap on the side of the unit.

Verify that both ends of the twisted pair
cables use 568B crimp pattern.
No signal
Status LED is off
Incorrect cable
connection
Swap the twisted pair cables in the AV and
HDCP RJ45 inputs on the receive balun.
No signal Insufficient power Verify the power supplies are connected to
both the send and receive baluns.
Verify the power LEDs on both the send
and receive units are brightly illuminated.

issues
Power off the destination device and power
it back on to force renegotiation.
Unplug and re-plug the HDMI cable from
receive balun to force renegotiation.

Video signal exceeds
bandwidth of cabling
Use shorter runs of twisted pair cabling.
Drop the HDMI signal to the next lower
resolution; i.e., decrease resolution from
1080p to 1080i, etc.
Replace the twisted pair cable with a
higher grade twisted pair cable; i.e.,
replace Cat 5e with Cat 6.

If the destination device is incapable of
displaying the video signal, alter the source
signal; i.e., decrease resolution from 1080p
to 1080i, etc.

Change source device to output PCM other
than Bitstream audio
Enable PCM down sampling if supported
