Installation & Use
English
!!! IMPORTANT !!!
Do not connect any other electronic devices to the RJ45 ports!
The extender MUST never be connected to your network!
Cat.5/6 connection cable
Please use Shielded Twisted Pair cable to connect the transmitter and
receiver. The longer the length of cable used, the higher the quality of the
cable must be.
For distances up to 50m standard patch cables may be used. For longer
cable runs RJ45 cables with solid cores (network installation cable fitted
with RJ45 connectors) will provide the best results for picture clearness.
When available please use low skew RJ45 cable. A cable with high skew
will cause the RGB signals to arrive at different time at the monitor and
red, green and blue pixels will not match to give a white dot or vertical
line but a colour fringe dot or line.
•
Connect the transmitter to your VGA source and to an available USB
port to power up the extender. The USB port must be self powered to
supply up to 0.5A to the extender. If no USB port is available please
use a USB power supply that provides 5VDC with at least 0.5A, i.e.
LINDY No.73093.
•
Connect one end of the RJ45 twisted pair connection cable. Use a
direct connection cable if possible. Avoid additional connections. Never
connect to electronic devices on your network!
•
Connect the receiver to your VGA display and to the RJ45 cable and
switch on the devices.
EDID / DDC emulation
•
The transmitter uses a predefined data set of common resolutions
(DDC data) up to 1920x1200 and 1080p. If the resolution of your
display cannot be set correctly on your video source (computer) or if
certain emulated resolutions shall not be selectable at all, please copy
(clone) the DDC data from your display into the transmitter unit. To do
so power the transmitter via its USB port, then connect it to your
display and power up your display. The yellow LED on the transmitter
will flicker rapidly for 2 to 3 seconds while the monitor’s DDC
information is stored permanently. Disconnect the transmitter and
install it as described above. Please note that the original EDID data
cannot be restored by the user. If a problem occurs while copying the
DDC data, the yellow LED will show a number of distinct flashes. Note
the number of flashes and contact the LINDY support team.
Sharpness adjustment
•
Use high contrast large black characters on white background (Word or
text editor file). Adjust the screw on the receiver for optimum sharpness
on your display.
•
If vertical edges and lines show coloured shadows the skew of your
RJ45 connection cable is too high. In this case use a Cat.5 VGA
extender with skew compensator or a lower skew cable.
LED indicators
The receiver is powered from the transmitter via the RJ45 cable. The
transmitter always performs a check before applying power to the RJ45
cable, which is shown by flashing the yellow LED. When power is
applied, the yellow LED will remain on.
The transmitter will disable the power and begin flashing its yellow LED
if:
o
The RJ45 cable is disconnected
o
Line power is overloaded
Standby and power saving mode
If the host computer goes into standby (turns off the display screen,
usually by disabling sync pulses) the transmitter will disable line power
and go into a low power mode after a period of approximately 16
seconds. The yellow indicator will remain off until video input is restored.
Trouble Shooting
English
If you are experiencing problems with the video quality please check for
the above mentioned topics, especially the last bullet point in previous
column (Cable Skew).
If problems cannot be solved please contact the LINDY support team. It
may be helpful to note the LED status information.
