then reapply power.

Connector Descriptions:

1. Stereo Audio Input – Connect a line level source. Audio will be present at the

DIGI-VGASD2-R audio outs. Video signal is not required for audio to pass.

2. Stereo Audio Output – Connect to desktop speakers. This is a “Loop Output”

which receives signal from the transmitter’s audio input.

3. VGA Input – Connect to laptop or other VGA source.

4. VGA Output – Connect to your PC Monitor This is a “Loop Output” which

receives signal from the transmitter’s VGA input.

5. IR IN – Connect a VGASD2-EYE (not included) to this port. The IR eye will send

IR information to the DIGI-VGASD2-R for the purpose of controlling the display
with the OEM remote.

6. IR OUT – Connect a VGASD2-EMT (not included) to this port. IR information

sent from the DIGI-VGASD2-R will be emitted for the purpose of controlling
the source with the OEM remote (place the emitter over the source’s IR
window).

7. EDID Mode – Use a small screwdriver to adjust the DIP switches to the desired

EDID mode

8. EDID Copy Button – This activates the EDID copy operation when EDID Mode is

set to “COPY”

9. EDID Status – This LED will flash when EDID is being copied successfully.

10. Power inlet – Connect the (included) 12vDC, 2A power supply.

11. Twisted Pair Output – Connect this to the DIGI-VGASD2-R using Cat5e (or

equivalent) cable.

12. Power LED – Lit when unit is ON.

13. RS232 Pass-through – This connection allows RS232 commands to be passed

through the extenders. Connect a control system to either end, and control
the remote source or display.

Installation Instructions:

1. Install units securely using attached mounting ears.

2. Set EDID Mode DIP switches to desired mode

(target resolution).

3. Connect twisted pair cable between the transmitter

and the receiver (DIGI-VGASD2-R). Ensure T568B
straight-thru wiring.

4. Connect VGA, audio, and control cables between

the display and the receiver (DIGI-VGASD2-R).
Connect ONLY IR or RS232.

5. Connect VGA, audio, and control cables between

the source and the transmitter (DIGI-VGASD2-S).
Connect ONLY IR or RS232.

6. Connect the included power supplies to the

transmitter and receiver.

7. Power on attached audio/video devices.

8. Adjust trim pots on the receiver until color levels in

the image are equal and any video “streaking” is

not visible in the image. Start with Green, then
Red, then Blue.

DIGI-VGASD2-S Installation Guide

VGA, Audio, & RS232/IR over Twisted Pair Transmitter

The Intelix DIGI-VGASD2-S transmits computer video, stereo audio, and control signals over a single twisted pair cable, such as Cat5e or Cat6.

The DIGI-VGASD2-S features local computer video and stereo audio output.

The DIGI-VGASD2-S features built in EDID tables that emulate common resolutions (1024x768 and 1280x800). The DIGI-VGASD2-S features
an EDID copy function that will copy all EDID information from the destination device. The DIGI-VGASD2-S will retain the copied EDID
information if power is disconnected.

The DIGI-VGASD2-S features up to 1920x1200 computer video performance and high-fidelity 20Hz to 20kHz audio performance extension up
to 350 feet. The DIGI-VGASD2-S features bi-directional IR and RS232 extension up to 350 feet.

 Distances, picture and audio quality may be affected by cable grade,

cable quality, source and destination equipment, RF and electrical.

Important notice:

 Do not attempt to disassemble or alter

the extender housing. There are no user­serviceable parts inside the unit. Doing so
will void your warranty.

 To minimize the possibility of equipment

damage from electrostatic discharge
(ESD), all source and destination
equipment must be powered off during
installation.

 Do not connect the extender to a

telecommunication outlet wired to
unrelated equipment. Doing so may
damage the unit or any connected
equipment. Ensure all connected twisted
pair cabling is straight-through (point-to­point).

 Allow proper ventilation to reduce the

risk of thermal failure.

Twisted Pair
Wiring - Use

T568B wiring

for Cat5e/6

connection

between send

and receive

units.

RS232 Wiring:

Consult the
manual of the
control devices
to determine
which pins the
TX/RX signals are
carried on. Be
sure to ALWAYS
connect TX to RX
and RX to TX.

Troubleshooting tips:

1. Noisy Audio – Increase the

source volume

2. Horizontal scrolling video bars –

Ground loop problem - try lifting
or grounding the transmitter or
receiver (VGA capture nut is a
ground)

3. No video – Perform EDID copy on

transmitter, check Cat5 cable,
check source settings (is it on?)
