2.1

Concepts and meanings for the items and parameters on the configuration page are as follow.Read the following content before any configuration operation.

Module Info

Information about modules will be shown in the Module Info panel after configuration. The

information includes chip type, resolution, scan rate, data flow direction, decoding and data

set counts. The last received settings for these parameters will be set as their default values

next time when this page is opened.

Click button on the right for details about the Modules and these detail information will

be shown on the Details Of Module dialog, as in Fig.11. Shown in the Run Line Table is the

routing that LED lights are lighten.

Fig.11 the Details Of Module page

Cabinet Info

Pixel array size and module cascade direction can be set in this panel. Note that the Regular

panel is for regular cabinets parameters setting and the Irregular panel is for irregular cabinets

parameters setting.

Width/Height

These two items specify the width and height of the cabinet pixel array. Note that the two

numbers circled in Fig.12 are the maximum values that can be set, which could also be namedas Maximum Width and Maximum Height.

Maximum Width

Maximum width varies with parameters of refresh rate, gray scale levels, and shift clock

frequency. Normally, the higher the refresh rate is and the finer the gray scale levels are, the

smaller the maximum width will be; while the higher the shift clock frequency is, the larger

the maximum width can be. But as the shift clock frequency is limited by driver chips and

module design, the maximum width is also limited.


11/35

( ) 86 2 84507048 ( ) 86 755-33592492

. .

Maximum Height

It is related to the module design.

Fig.12 the Regular panel

Symmetrical Output

If selected, the two 50pin output ports of a scan board will work for the left and the right half

of the cabinet pixel array respectively.

D clock as the second road extended to 32 sets of data

If selected, the scan board will provide 32 sets of output data for the cabinet.

Image Refresh Rate

This is the rate images shown on a LED display are update. The higher the image refresh rate

is, the video is more stable for watching.

Gray Scale

Normally, 256 levels of gray scale is enough for two-color LED displays, 4096 levels enough

for indoor full color LED displays, and 16384 levels enough for outdoor full color LED

displays. And apparently, the more levels the gray scale is divided into, the more exquisite the

shown images will be.

Gray Mode

There two options for Gray Mode, Traditional and Advanced. Traditional mode is for normal

use and it has lower brightness loss. In Advanced mode, image refresh rate can be greatly

increased, but the cost is 8% of brightness loss.

Accelerate Rate

This parameter is used to increase the image refresh rate. If N is selected, the image refresh

rate will be increased by N times. For Traditional Gray mode, 1, 2, 4 and 8 are available for N.

And for Advanced Gray mode, 1, 2, 4, 8 and 16 are available for N.

DCLK Frequency


12/35

( ) 86 2 84507048 ( ) 86 755-33592492

. .

This is the shift clock frequency. The shift clock frequency depends on the performance of

driver chips and the circuit design of the modules. The higher the driver chip performance is

and the better the module circuit design is, the higher the shift clock frequency can be. A

higher shift clock frequency will results in a larger pixel array, more gray levels or higher

refresh rate that a receiver card can support.

Occupy

This is the duty cycle for the shift clock. The shift clock frequency can be increased by

changing this parameter. Normally, the duty cycle should be set as 50%.

Phrase

By phrase here refers to the time relation between the shift clock and the corresponding data

to be shifted. This parameter can be used to eliminate the errors due to the phrase, such as

image dislocation and flashing pixels.

Blank Interval

This is the line blanking interval. This parameter can be used to weaken the decoy. Increase

the value of this parameter if decoy is serious.

Line Change Point

This parameter refers to the time to switch to the next row. It is used in conjunction with

Blank Interval to weaken the decoy of scan mode LED displays.

Control End Point

This refers to the time to end the process for weakening decoy. It is used in conjunction with

Blank Interval and Line Change Point to weaken the decoy.

Smart Configuration

Smart configuration is for automatic detection of the module driven mode and signal flow

direction. Counts of steps for smart configuration could be different as some of the steps may

be skipped if certain information is known. Cabinets will be able to work after smart

configuration is successfully performed.

Load File

Load the pre-saved settings to the received card from a configuration file.

Save FileSave the information of modules, cabinets and other parameters to a .rcfg file.
