DIGI-VGASD2-T8 Installation Guide
VGA, Audio, & RS232/IR over Twisted Pair Transmitter with Multiple Outputs
Rev. 120821
The Intelix DIGI-VGASD2-T8 transmits computer video, stereo audio, and control signals to eight remote destinations over a single twisted
pair cable, such as Cat 5e or Cat 6.
The DIGI-VGASD2-T8 features local computer video and stereo audio output.
The DIGI-VGASD2-T8 features built in EDID tables that emulate common resolutions (1024x768 and 1280x800). The DIGI-VGASD2-T8
features an EDID copy function that will copy all EDID information from the destination device. The DIGI-VGASD2-T8 will retain the copied
EDID information if power is disconnected.
The DIGI-VGASD2-T8 features up to 1920x1200 computer video performance and high-fidelity 20Hz to 20kHz audio performance extension
up to 350 feet. The DIGI-VGASD2-T8 features bi-directional IR and RS232 on Output 1, and uni-directional (transmitter to receiver) IR and
RS232 on all other outputs.
Connector Descriptions:
1. Power LED –Lit when unit is ON.
2. ACT LED –Will flash when IR or RS232 data is passing through the system
3. Power inlet –Connect the (included) 12vDC, 2A power supply.
4. EDID Mode –Use a small screwdriver to adjust the DIP switches to the desired EDID mode
5. EDID Copy Button –This activates the EDID copy operation when EDID Mode is set to “COPY”
6. EDID Status –This LED will flash when EDID is being copied successfully.
7. RS232 Pass-through –This connection allows RS232 commands to be passed through the extender connected to [Output 1]. Connect
a control system to either end, and control the remote source or display.
8. 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.
9. IR OUT –Connect a VGASD2-EMT (not included) to this port. IR information sent from the DIGI-VGASD2-R connected to [Output 1]
will be emitted for the purpose of controlling the source with the OEM remote (place the emitter over the source’s IR window).
10. 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.
11. Stereo Audio Output –Connect to desktop speakers. This is a “Loop Output” which receives signal from the transmitter’s audio
input.
12. VGA Input –Connect to laptop or other VGA source.
13. VGA Output –Connect to your PC Monitor This is a “Loop Output” which receives signal from the transmitter’s VGA input.
14. Twisted Pair Outputs –Connect these to (8) DIGI-VGASD2-R using Cat5e (or equivalent) cable.

you wish to copy, apply
power to the transmitter,
and press the copy button.

*Note: The unit must be off during DIP switch changes. Be
sure to disconnect the power adapter, adjust the switches,
then reapply power.
Important notice:
Do not attempt to disassemble or alter the extender
housing. There are no user-serviceable 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-
to-point).
Allow proper ventilation to reduce the risk of thermal
failure.
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?)
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-T8). 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.
Twisted Pair
Wiring - Use
T568B wiring
for Cat5e/6

between send
and receive
units.
