Intelix DIGI-HDMI-HR
Installation Manual
Introduction
The active Intelix DIGI-HDMI-HR balun transmits an HDMI (high-definition
multimedia interface) audio and video signal up to 150 feet via inexpensive
twisted pair cabling, such as Cat 5e or Cat 6. The DIGI-HDMI-HR supports
standard HDTV resolutions and is HDCP compliant.
Two individual runs of twisted pair cable are required when installing the
DIGI-HDMI-HR balun. The unit is fully compatible with Cat 5e and Cat 6. In
environments susceptible to high electromagnetic interference, two shielded
twisted pair cables should be used.
The Intelix DIGI-HDMI-HR includes one send balun, one receive balun, one
power supply, and two mounting brackets. The system is powered on either
the send or receive end.

Caution: Do not attempt to disassemble or alter the balun housing. There are no
user-serviceable parts inside the unit. Doing so will void your warranty.
To install the Intelix DIGI-HDMI-HR baluns, perform the following steps:
1. Turn off power and disconnect the audio/video equipment by following the
manufacturer’s instructions.
Caution: To minimize the possibility of equipment damage from electrostatic
dischar
installation. This includes signal extenders, splitters, and switches.
2. Make certain that outlets and cross connects to which you will connect the DIGI-
Caution: Do not connect the balun to a telecommunication outlet wired to
unrelated equipment. Doin
Ensure all connected twisted pair cabling is straight-through (point-to-point).
3. Verify the desired twisted pairs are not being used for other LAN or telephony
Note: For your convenience, it is recommended that you uniquely mark the ends
of the twisted pair cable before pulling them through a wall or conduit.

an HDMI cable. Be sure to test both HDMI cables required for system installation.
5. Connect the DIGI-HDMI-HR send balun to the HDMI output of the video source.
6. Connect the DIGI-HDMI-HR receive balun to the HDMI input of the receiving
device at the remote end. Do not connect the 5V power supply.
7. 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.
8. Connect the 5V power supply to the send or receive DIGI-HDMI-HR balun.
9. Power-on the video equipment.
10. Verify picture quality.
