6. Special Function Instruction


6.1 Point to point correction

6.1.1 Start the “LED manager 2010” (see Figure 6-1)





6.1.2 Select Point to Point Correction Function

After the setting of the screen, click the "Screen Correction" under the "Tools" option.(see Fig 6-2)






6.1.3 Check the Correction Result

Select "Open correction" under the "Screen Correction", then click the button "Save to Screen"(see Figure 6-3) , and now you could check the correction result on the screen.





6.2 Environment Monitoring

6.2.1 Installation Instruction






Notice: Environmental monitor is combined with the temperature and humidity probe for use. The temp&humi.probe is with shield and free of wind and water (the rain), so it can be installed outside the screen. Illumination probe is also wind and water resistance, and generally installed on the decorative edge (frame) of the screen, with the same direction as that of screen face.


6.2.2 Software Operation

After connecting the Environment Monitor and installing the probes, open the "LED Manager 2010",click the "Environment Monitoring" under the menu of "Settings" (see Figure 6-5)





In "Environment Monitoring", it lists the specific data of the current brightness, temperature, and humidity. Besides, if we add the temperature and humidity window in the playing program, the temperature and humidity parameters will real time display on the screen.


In "Environment Monitoring", click the "Monitor Settings",you can set some parameters for the environment monitor (see figure6-6 below).The sending card's port connected with the monitor should be set correctly, otherwise the software can not read the data correctly. Additionally, from this window we can find: the recommended brightness probe scope is 0-4000Lux, temperature probe scope is -10-60 Celsius Degree, and humidity probe scope is 0-100%RH.





The software offers” Start up Automatic Brightness Control” check box, and if this item is selected, when the software finds the monitor the software will adjust the illumination automatically according to the brightness value. If this item is not selected, the software just indicates the brightness value but won't adjust the brightness automatically according to the monitoring.“Start up Automatic Brightness Control” is not selected as the default setting.


The software window offers four options for LED screen: Minimum Brightness, Maximum Brightness, Current Brightness, and sensitivity.


●  Minimum Brightness: It indicates the minimum brightness of the screen (never less than it) when the screen is automatically controlled by the monitoring device. The maximum value is 100, the minimum value is 1. (Filling in integer between 1 to 100,not allowing the decimal).This value is set by customer and the original default value is 50.

● Maximum Brightness: It indicates the maximum brightness of the screen (never exceed it), when the LED screen is automatically controlled by the monitoring device. The maximum value is 100; the minimum value is 1(Filling in integer between 1 to 100,not allowing the decimal).This value is set by the customer, and the original default value is 100.

● Current Brightness: It shows the data of brightness synchronously with the monitoring. This number is restricted by the Maximum and Minimum Brightness, it is between them.

● Sensitivity: It supplies five ranks of choice, it decides between what scope of the environmental brightness that the monitor will react.(See the follow figure 6-7)


  Sensitivity   1(Maximum)   2    3 (Default)   4    5(Minimum)
  Responding scope   0 to 4000Lux   0 to 4000Lux   0 to 1200Lux   0 to 800Lux   0 to 500Lux





All the data could be adopted according to the requirement, we could set up the "sampling rate", we could choose 1s, 5s,30s,60s,300s,600s, and this data decide the frequency that the software refreshes brightness, humidity and temperature. For example, if we choose the sampling rate at 600s, then the every 600s, the software refreshes the brightness, humidity and temperature, meantime conduct a brightness automatic adjustment. The original default setting is 10s.


The priority of the Automatic Brightness Adjustment, Timing Brightness Adjustment, and Manual Brightness Adjustment is set forth below:

●  Whether the Automatic Brightness Adjustment or Timing Brightness Adjustment is adopted, the Manual Brightness Adjustment is available.

●  When adopt the Automatic Brightness Adjustment, the Timing Brightness Adjustment is void.



6.3 Fiber Optical Transmitting

In the diagram below, device 1 is PC, device 2 is sending card, device 3 is receiving card, device 5 is photoelectric converter. The devices are usually connected with CAT-5E, and this cable's transmitting distance is 100M.If the distance is more than 100 M, we propose to adopt optical fiber transmission. Between two devices, we use CAT-5E and photoelectric converter to connect, and between two photoelectric converters we use optical fiber to connect. Multimode fiber's transmission is more than 500M, single mode fiber 'transmission is up to 10KM.Note: between every two devices, photoelectric converter can be adopted to prolong the transmitting distance.
