Function Introduction
BX-V75 receiving cards used for all kinds of full color LED display screen, support most of the module chip.
12nos T75 port on board, data, refresh rate can be reached to 5000Hz. Support Gigabit mode,
asynchronous player and BX-VS/VSE/VHE synchronous sending card. Users can update the firmware
online.
Simple install
Adopt the standard interface, standard hole specifications. Support connecting indicator
light and test button from outside; 2 gigabit Ethernet ports; Support exchange of input and
output. 12nos T75 on board.
Interface
12nos T75 port on board, support E signal, maximum 32 scan mode, signal outputs.
Support exchange the data from any interface, RGB colors will exchange in orders.
Split mode
Support 2 split modes, 3 split modes and 4 split modes, for width, can be different.
Example: 2 split modes: first one is 128 pixels, another one is 64 pixels; 3 split modes: first
one is 128 pixels, middle one is 128 pixels, last one is 64 pixels.
Data direction can be changed
Default is from right to left. According to your requirements, you can set as “left to
right””top to bottom””bottom to top”.
Support special-shaped screens
Support excursion of display data ( from range 0-511 pixels). And maximum, you can set
384 in height for excursion.
Many scan modes
Use LedshowTV software, and support 32, 16, 8, 4 scan modes; Support without 138, and
support 595, RT958 etc. By smart scan function, can support static screen, 2 to 32 scan
modes.

Compatible with many chips
Support normal chip, PWM chip.
Better effects
Adopt high refreshment technology, support high refreshment and high gray scale.
Support 256,512、1024, 2048, 4096, 8192, 16384, 32768,65536.
Used for all kinds of situations, outdoor or indoor. Users can get a good effect by adjusting
the refresh rate, display mode, etc.
Clock adjustment
Support adjustment from 10.42MHz to 31.25MHz. Satisfy cascade characteristics of
different modules, has better effect. On the promise of refresh rate, will increase the width.
Blanking adjustment
Adjust the blanking, as to adjust the virtual light.
Maintenance
Receiving card supports read back function of configuration parameters; Support update
online; It is convenient for customers to update and maintain.

Control Size
Better to control the sized smaller than 256*256, you will get a good effect.
The effect is depending on the width of the screen, as to be more clear, please check the below

Note:
The upon scan modes are for straight lines. If your scan mode is 1/4, one data has 8 lines,
you should choose the data of 1/8; If your scan mode is 1/4, one data has 16 lines, you
should choose 1/16.
If it is OK, you can use split mode as to improve the display effect.

Adjustment Guiding
Choose Parameters
Display mode
Now, we have two modes, refreshment priority and brightness priority. Refreshment
priority is for high refresh rate, and you will get good feedback by mobile phone or camera,
but the brightness is lower. If you use brightness priority, you will get higher brightness but
photo by mobile phone or camera may not so good. Usually,for indoor screen, brightness is
not so important,so you can choose refreshment priority;But for outdoor screen,brightness
is needed,in this situation,need to choose brightness priority.
Brightness mode
For brightness mode, there are 3 modes: lower, normal or high brightness. If the display
mode is fixed, then, the higher the brightness is, the lower the refreshment will be. Or, on
the same refreshment, the control width will be smaller. So, when the brightness is enough,
you can choose lower brightness mode, as to obtain a better refresh rate and shooting
effect.
Gray grade
On the same refresh rate, if the control size is the same, then, the gray grade is higher,
the effect will be better. But if the gray grade is higher, the control size will be smaller. So, we
usually suggest to use 4096 gray scale, do not over than 16384.
Refresh rate
It is not correct that the refresh magnification is higher, the effect will be better. If the
refresh rate is enough, the refresh magnification is lower, the shoot effect will be better.
Replacement clock
Replacement clock is also an important parameters. The higher the replacement clock is,
the control size will be larger(on the same refresh rate). But some kinds of modules are not
so good with quality, cannot use higher replacement clock, usually, there will be some
special flashing on the screen.
Gray from the first grade
If users need better low gray effect, you can choose. But the effect will be not so good, it
will be weird by your eyes. So, usually, we do not suggest.

FAQ
Gigabit or Sending card
If need better shoot effect, choose sending card mode.
Is there any affect for shooting by environment?
Usually, the environment brightness is the biggest fact for shoot. Cause the time of the
camera shutter is according the the environment brightness.
In indoor, the brightness is lower, so, the shutter will be slower, usually, 1/60 - 1/200 seconds.
In this situation, if the refresh rate is about 1000, the shoot effect will be better.
But if in outside, the brightness is higher, the shutter time will be faster, usually, faster than
1/800 seconds. In this situation, the refresh rate should be about 3000.
So, for same screen, the shoot effect in night is better then in day. And that is the reason why
outdoor screen needs a higher refresh rate.
