LED VIDEO PROCESSOR 8
Notes: LVS5066 adopts 2-level switching architecture. Level 1
switching is input pre-selection switching, namely the switching
among 4 signals in a single channel; Users can proceed to level 2
switching namely switching between channels until all inputs
pre-selection of each are completed. which is used to realize a series
special switching effects such as seamless switching, fading-in/out,
WIPE or used to select PIPs. Seamless switching can be realized
among signals in channels.
2) Select output brightness
Button names Description
BRT - Decrease output image brightness of
LVS5066, the lowest brightness is 0.
BRT + Increase output image brightness of LVS5066,
the highest brightness is 64.
LVS5066 supports 32 levels Brightness, “0” represents the
lowest brightness, and 64 represents the highest brightness. To
ensure full gray level of output image, normally the output
brightness is set as 64!
3) VGA input auto adjustment (Auto)
With this button, LVS5066 can automatically adjust the
sampling parameters of VGA input signals to make VGA picture
clear and complete. Operating procedures: when the main output is
the VGA input signal, first press VGA input selection button of the
channel, for example, VGA button of Ch3. Press “Auto” button
before the message “Source Ch2.=VGA” disappears in the screen.
In general, this operation is made only when new VGA signal
source is to be connected in. The time spent in auto adjustment
may vary with the conditions of signal source, but it is usually
shorter than 1 minute. Sometimes user need repetitively do such
adjustment till VGA picture looks clean, complete and stable.
4) Information display (Info)
This button can be operated to display the Current settings of
LVS5066.
press Info button to display current settings and information of
LVS5066. There are total 29 entries of information. Press “Info”

button again before the information disappears in LCD, the next
entry of information will appear in LCD.
5) CUT mode
LVS5066 will automatically enter seamless switching mode
after startup. Now the indicator is ON. If the moment LVS5066 is in
other switching modes, you can press CUT button to enter
seamless switching mode. The system will realize seamless
switching between the six channels, i.e.: Ch1, Ch2…Ch6. The
picture will change fluently and stably without flicker, tremble, stasis,
delay, tearing or black screen occurring.
PS: the switching between different signals of current channel
will lead to black screen. The above switching effects are only
realizable in the switching between different channels.
6) Fade-in/Fade-out(Fade)
Press Fade button while in operation mode, LVS5066 will enter
Fade-in/Fade-out(Fade) mode, the moment the switching time
“Fading Time= N Seconds”will appear in LCD (N represents the
number of seconds, e.g.: 1, 2, 3…). The moment, the system can
realize seamless switching between the 6 channels, i.e.: Ch1,
Ch2…Ch6 without any tremble or interference occurring.
While in Fade-in/Fade-out(Fade) mode, user can press Fade
button to change fading time.
7) Fader mode
Press Fader button while in operation mode, LVS5066 will
enter Fader mode. Now you can operate T-Fader manually to
control the fading process, or stop it halfway to make new picture
and old one overlay each other in transparent mode. LCD displays
the ratio of the signals in the recent two channels, e.g.: “CH3=100%
CH5=0%”.
Operating procedures: press a button to select the channel to
be switched, then push T-Fader forward or backward, the image will
change in fading-in/out mode. If no signal is selected, when T-Fader
is pushed, the screen will return to the picture of the channel most
recently displayed.
8) WIPE mode

LVS5066 User’s Manual
---------------------------------------------------------------------------------------------------
LED VIDEO PROCESSOR 10
LVS5066 supports 4 WIPE modes. Press WIPE1, WIPE2,
WIPE3 while in operation mode, LVS5066 will enter corresponding
wipe mode, the moment corresponding mode will appear in LCD
(e.g.: “Switch Mode= Wipe: L→R”). Table below lists the
descriptions of each switching mode and their respective operation
buttons:
Switching
direction Description of mode Buttons
L→R Wipe from the left toward the right
L←R Wipe from the right toward the left
WIPE1
(as
described
in note)
L←M→R Wipe from the centre toward both
sides
WIPE2

centre perimeter
WIPE3
Note: Both L→R and L←R modes (as described in above
table) are operated using WIPE1 button. User can press this button
to switch the modes.
9) PIP / POP
LVS5066 has PIP function, that is to say, it can add a zipped
picture (PIP) to current picture (background). The PIP can be

between PIPs is made in Fade-in/Fade-out(MIX) mode.
Operating procedures:
Enter PIP display mode: press PIP button while in any mode,
LVS5066 will enter PIP mode, in the meantime, the information on
the background channel and the position and channel of PIP to be
added will appear in LCD, e.g.: “Background=CH2，PIP_3=CH5”.
Select PIP: while in PIP mode, select 1 channel from the 6
channels, the picture in this channel will be set as PIP.
Change position of PIP window: press PIP button while in
PIP mode, the position of the PIP in LCD will become vacant, e.g.:
“Background=CH2，PIP_3=CH”. Press PIP again, PIP will move to
another position. When PIP arrives at the position you selected
(e.g.: PIP_4), reselect PIP channel (e.g.: CH1), the PIP will appear
in the new position after a Fade-in/Fade-out action (the moment

LVS5066 User’s Manual
“Background=CH2，PIP_4=CH1” will appear in LCD).
Change the background: you must first switch LVS5066 into

Notes: Users must switch to current channel under operation
model and enter into set menu to set the size and position of PIP
pictures.
Items 29: “PIP _Frame”
Users can set the width of black frame of images by themselves. If
the value is set as “0”, it means that PIP has no black frame. If it is set
as “1”, it means PIP has a black frame of 1 pixel wide. The maximum
value of the black frame width is 16.

10. Factory district setup
The following settings must be made by relevant qualified
technicians or the guidance of the plant technician, otherwise the
incorrect and improper operation will result to abnormal situation.
Item31:“Init”
While in operation mode, press SETUP for 8 times continuously,
“Password: 8 Enter Setup …” will appear in LCD, LVS5066 then
enter item 1 setup, then press SDI button of Ch1 once, LVS5066 will
then enter item 31 setup “Init”. Press “ ←” or “ →” ro select “ OK”,
then press Enter, the processor will be reset to default settings made
in factory, and the system will remind you “the device has been reset,
please power off it then restart it”, please operate following this
instructions.
Item 32: “Auto ADC”
After inputting the analog signal to the video processor who’s ADC
has not been revised, the picture on the display may appear some bad
phenomena, such as color cast, extreme-darkness. LVS5066 can
overcome all of problems by automatically revising white balance in
terms of the input analog signals (AV, YPbPr and VGA). Figure below
shows the method of “Auto ADC”.
When switched to the corresponding analog input signal, the
processor will receive and output the signal to the LED display, then,
get into the No.18 Item, press “ ←”or “ →” to select “ Yes”, at last, press
“ Enter” to carry on auto ADC.
Caution: All video processors have gone though the auto
ADC, please use this item delicately!
Item 33: “Bias”
In order to decrease the noise on gray scale display, the LED
display system usually removes the lower gray scale one of all input
signals, which will cause the lose of the video information, especially
in dark scene ,such as night view.

LVS5066 User’s Manual
---------------------------------------------------------------------------------------------------
LED VIDEO PROCESSOR 20
LVS5066 can improve problems as follow mentioned by adjusting the
“ Bias”, whose limit ranging from 0 to 32. When losing the signal of dark scene,
you can restore the drop-out information to the LED display by increasing the
value.
Normally in order to keep the completeness of output signals, the
standard value is set as 0!
