Congratulations on your purchase of the Wireless VGA LR. Your complete
satisfaction is very important to us.
Gefen
Gefen delivers innovative, progressive computer and electronics add-on solutions
that harness integration, extension, distribution and conversion technologies.
Gefen’s reliable, plug-and-play products supplement cross-platform computer
systems, professional audio/video environments and HDTV systems of all sizes
with hard-working solutions that are easy to implement and simple to operate.
The Gefen Wireless VGA LR
The Wireless VGA Extender LR allows a VGA display or projector to be
conveniently located up to 100 feet away from the source.
The Wireless VGA Extender LR features line-of-sight signal transmission and
through walls at resolutions of up to 1280x1024, using industry-proven 2.4GHz
802.11b/g/n Wireless network technology. The Extender can be operated on any
one of 4 channels to minimize interference.
How It Works
This product is a plug-and-play solution. No special configuration is necessary.
The Wireless VGA Extender LR system consists of a Sender and a Receiver.
The Sender is connected to the VGA source with a VGA cable. The Receiver
is connected to the display with a VGA cable. 12V external power supplies are
connected to the Sender and the Receiver.
Supported A/V input sources also include Component, S-Video and Composite
Video. A/V sources can be individually selected by pressing the Source Selector
button on the front panel of either the Sender unit or the Receiver unit. The
current wireless channel can be selected in the same way with the Channel
Selector button.

OPERATION NOTES
READ THESE NOTES BEFORE INSTALLING OR
OPERATING THE WIRELESS VGA LR
• The Wireless VGA LR will accept component video signals (YPbPr) up
to 1080p. However, 1080i and 1080p signals will be down scaled and
transmitted at 1280x720. Please see the table at the bottom of this page for
a list of input and output resolutions and framerates.
• For better transmitting quality, please do not place units into cabinets or
cupboards that will reduce the wireless transmitting signal. Also, please note
that only one set can be used at any given time at a location. Multiple sets in
close proximity may cause interference with each other.

How to Setup the Wireless VGA LR Sender Unit
1. Connect source devices to the Wireless VGA LR sender unit. The sender
unit has the following connection options:
VGA
Component
S-Video
Composite
2. Connect a single analog audio source to the Wireless VGA LR sender unit
using a 3.5mm mini-jack audio cable.
3. Connect one or both of the following output device types to the Wireless
VGA LR receiver unit:
VGA (VGA cable included)
Component
4. Connect a single analog audio output device to the 3.5mm mini-jack output
on the Wireless VGA LR receiver unit.
5. Connect the included 12V DC power supplies to both the Wireless VGA LR
sender and receiver units.
6. Toggle the power switch on both the Wireless VGA LR sender and receiver
units.
7. Turn on all output and source devices.
How to Operate the Wireless VGA LR
Once all units, sources, and output devices are powered and turned on, the
sending and receiving units will begin their boot-up sequence.
During this sequence all channel LEDs (blue) on the sender and receiver units
will turn on and remain on. The output will display a blue screen with the text:
“Wi-Fi initial...”
Once the initial boot-up sequence is complete, the currently selected input (on
the sender) and output (on the receiver) will be active (blue). The LED for the
channel in operation will also be on (blue). The output will display a blue screen
with the text:
“Search channel XX” (where XX is the current channel)
During the final stages of the boot-up sequence, the Wi-Fi LED should turn on
(green) while the sender and receiver units attempt to establish contact with each
other.
Once a link has been established, the Wi-Fi LED will begin to blink rapidly. This
will indicate that data is being transmitted from the sender to the receiver unit.
Video should now be output through the Wireless VGA LR receiver unit.
CONNECTING AND OPERATING THE WIRELESS VGA LR

11
CONNECTING AND OPERATING THE WIRELESS VGA LR
If the Wi-Fi LED remains on (green) and does not blink, the sender and receiver
units are not linked and video/audio is not being transmitted. When this occurs,
video will not be displayed and the output will remain on a blue screen. This text
will be displayed:
“No Wi-Fi connection”
Try moving the sender or receiver unit’s location until a link is established and the
Wi-Fi LED is blinking green.
The Wi-Fi LED may occasionally blink red. This indicates low signal strength.
While the link between the sender and receiver units will most likely remain
intact, video/audio drop-outs may occur. Try moving the sender or receiver unit’s
location until a link is established and the Wi-Fi LED is blinking green.
If the Wi-Fi LED remains red, the signal strength is too low and no video will be
output. Try moving the sender or receiver unit’s location until a link is established
and the Wi-Fi LED is blinking green.
How to Switch Input Sources on the Wireless VGA LR
Use the switch button on the front panel of the Wireless VGA LR sender unit,
labeled “S”, to cycle between the available input sources. The currently selected
source will be indicated by a blue LED. Each press will progress to the next input
in the following order:
VGA Component S-Video Composite
How to Switch Outputs on the Wireless VGA LR
Use the switch button on the front panel of the Wireless VGA LR receiver unit,
labeled “S”, to cycle between the available outputs. The currently selected source
will be indicated by a blue LED. Each press will progress to the next output in the
following order:
How to Switch Channels on the Wireless VGA LR
If there is significant interference on a particular channel, or the currently selected
channel is unstable, changing the channel may alleviate the issue. To change the
channel, press the channel button, labeled “C” on either the sender or receiver
unit. Changes on one unit will automatically be reflected on the other unit. If there
is currently no link between the sender and receiver, the channel button will not
be operational.
