Intelix DIGI-VGASD-R
Installation Manual
Introduction
The Intelix DIGI-VGASD-R active receiver balun transmits VGA video,
stereo audio, and IR or RS232 up to 350 feet over a single twisted pair cable.
The unit features dual amplified outputs and adjustable video equalization.
When used with a compatible Intelix send balun, the DIGI-VGASD-R
provides 1600 x 1200 video performance and 20 Hz to 20 kHz, hi-fidelity
audio performance.
The unit requires power and includes a 5V power supply.

Installation
To install the Intelix DIGI-VGASD-R balun, 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 straight-
through.
2. Power-off the connecting audio, video, and control equipment.
3. Connect a compatible send balun to the VGA output of the video source,
the audio output of the audio source, and an IR or RS232 control source.
Do not connect the 5V power supply.
Note the DIGI-VGASD-R does not support IR and RS232
simultaneously. If both signals are connected, IR will take precedence
over RS232.
4. Connect the DIGI-VGASD-R receive balun to the VGA input of the video
destination, the audio input of the audio destination, and an IR or RS232
control destination. If required, connect a second video destination. Do not
connect the 5V power supply.
5. Complete the connection between the send and receive baluns using one
run of twisted pair cable. Ensure there are no split pairs or taps.
6. Connect the 5V power supply to the send balun.
Compatible Intelix send baluns include:
DIGI-VGASD-WP-S wallplate send balun
DIGI-VGASD-S modular send balun
DIGI-VGASD-T4 1 input by 4 output modular send balun
DIGI-VGASD-T8 1 input by 8 output modular send balun

7. Connect the 5V power supply to the DIGI-VGASD-R receive balun.
8. Power-on the connecting audio, video, and control equipment.
9. Verify picture quality. If necessary, adjust the signal using the blue, green,
and red dials on the DIGI-VGASD-R receive balun.
Warning! Do not use any IR receiver (eye) or IR emitter other than those
sold exclusively for the DIGI-VGASD series of products to prevent damage
to the balun. Using 12V-
b
ased IR components may permanently damage the
IR circuitry of the product and void the warranty.
Required IR Emitter: Intelix DIGI-VGASD-IREMT
Required IR Receiver: Intelix DIGI-VGASD-IREYE

Example System

Troubleshooting
Symptom Causes Possible Solutions
No signal No continuity in
video link
Verify cable continuity between pairs of
baluns.
Verify the max distance has not been
exceeded.
Verify the audio, video, and control
cables between the equipment and
hardware are connected and pass signal.
No signal Power off Check power supplies of video
equipment.
Verify the LEDs on both the send and
receive units are illuminated.
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.
Unusual colors
Rolling signal
Horizontal
video bars
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.
No control Simultaneous
RS232 and IR
Verify only IR or RS232 are being used.
Background
pattern
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.
