Intelix DIGI-DVI-F

Installation Manual

Introduction

The active Intelix DIGI-DVI-F balun allows a DVI (digital visual interface)
video signal to be transmitted up to 150 feet via inexpensive twisted pair
cabling, such as Cat 5e or Cat 6. The DIGI-DVI-F supports standard HDTV
and VESA resolutions, as well as the DDWG standard for DVI compliant
monitors. In addition, the unit is Mac compatible and HDCP compliant.

Two individual runs of twisted pair cable are required when installing the
DIGI-DVI-F balun. Two runs of Cat 5e are required for 480i, 480p, 720p, and
1080i video. In environments susceptible to high electromagnetic interference,
two shielded twisted pair cables should be used.

The Intelix DIGI-DVI-F includes a send balun, receive balun, and one power
supply. The system is powered on either the send or receive end.

Installation

To install the Intelix DIGI-DVI-F baluns, perform the following steps:

1. Identify the pin configuration of the baluns and RJ45 connectors on the
twisted pair cabling. To eliminate crosstalk, the pin configuration must
follow the EIA/TIA 568B standard. Please ensure that wiring is straight­through.

Warning! To minimize the possibility of equipment damage from electrostatic
discharge (ESD), all source and destination equipment must be turned off
during the installation of video equipment. This includes signal extenders,
splitters and switches.

2. Connect the DIGI-DVI-F send balun to the DVI output of the video
source.

3. Connect the DIGI-DVI-F receive balun to the DVI input of the receiving
device at the remote end. Do not connect the 5V power supply.

4. Complete the connection between the send and receive baluns using two
runs of twisted pair cable. Ensure that there are no split pairs or taps.

5. Connect the 5V power supply to either the send or receive DIGI-DVI-F
balun.

6. Power-on the video equipment.

7. Verify picture quality.

Symptom Probable Causes Possible Solutions

No video No continuity in video

link

Verify cable continuity between pairs of
baluns.

Verify the max distance has not been
exceeded.

No video Power off Check power supplies of video

equipment.

No signal Improper connection or

swapped pairs

Check that baluns are connected to
correct video inputs and outputs.

Verify both ends of the twisted pair cable

conform to the EIA 568B crimp pattern.

Improper grounding or
cable type

Verify the source and destination devices

are grounded. Different electrical circuits

may cause a voltage differential on the

building’s electrical ground plain. The

video display or source deceive may need

to be grounded.

EMI interference Identify possible radiating frequency

sources (i.e.; wireless LANs, switching

power supplies) and isolate them.

Replace any unshielded twisted pair cable

with shielded twisted pair cable.
