2.5 Data and Power Connection

LED display power cable is the cable connecting power distributor and LED screen. GB/CE/UK/UL standard 3*2.5 or 3*4 Sqmm cable is usually used. GB/CE/UK/UL 3*2.5 Sqmm cable loading capacity is not more than 4.5KW. GB 3*4 sqmm cable loading capacity is not more than 6KW. Please note to make wiring in accordance with the standard. Conventional method is horizontal cabling but there are some special situations who can choose only vertical wiring.

In three-phase and five-wire power supply mode, the load of each phase must be evenly distributed to achieve three-phase balance.

LED display data cables include HDMI, DVI and CVBS cables from signal source to processor, HDMI and DVI cables from processor to sending card, USB cable from computer to sending card, and network cable between sending card and receiving card.

Here we mainly talk about the network cable wiring between the sending card and the receiving card. The loading of a network cable cannot exceed 655360 Pixels, and it is a rectangular loading and snake connection wiring. In addition, the load of the sending card or video controller also has the limitation of width, height and total load, which must be considered comprehensively to avoid wiring errors.

Below are the sample about the power wiring and data wiring connection demonstration:

1. For the cabinet containing the receiving card, after the connection is normal, the LED screen will display a normal picture, but not a complete picture. In this case, it is recommended to read from the receiving card and save it to a file for backup, so as to avoid the incorrect operation of later staff to find the correct configuration file (.RCFGX).
2. For the LED screen without receiving card, the basic can be set intelligently according to the module information; Non-professional, you can find the manufacturer to get the correct RCFGX file, load it from the file, then send it to the receiving card, and finally solidify.

According to the previous network cable wiring, configure the display screen, change the number of receiving card columns, rows, and load width and height of receiving card. For MRV412, MRV416 and AXS series (A5s, A8s, etc.) receiving cards, you can open the Mapping function, see the cable routing mode, and then click the corresponding grid (grid is the front view), and then send to the hardware (Send to HW), solidification (Save). Finally, it can be saved to a file to avoid the loss of screen connection files by mis-operation.

After the connection, the screen displays into a complete picture. Well done!!

4.5 Other Important Tips for Moisture Protection

a) The daily running time of the LED Screen should be more than 1 hour (video can be played if there is no need for use);
b) Avoid air conditioner blowing directly on the screen, ensure that the ambient humidity of the screen is controlled at 70%.
c) Do not allow the LED Display beads to come into contact with water or wet rag.
d) Avoid touching the display beads directly with your hands or with items that can generate strong static electricity. (e.g., nylon, wool sweaters, etc.)

Illustration showing hands cleaning a surface with a spray bottle and a red X mark, likely indicating anti-smoking or disinfection.

Illustration showing a hand touching a grid with lightning bolts and a red X symbol, likely indicating electric shock or hazard.

(e) It's prohibited to use 84 disinfectant containing (Fluorine, Bromine) or highly effective disinfectant water to spray directly on the environment where the display is used. If disinfection is required, it's recommended that 75% medical alcohol be used and the power to the display must be turned off during disinfection. Prohibit flames, prevent static electricity, maintain ventilation and pay attention to safety.

(f) If the display has not been used for a long time (two use time not more than 5 days), be sure to dehumidify before use, using a gradual increase in brightness, slow warming to remove the accumulated moisture in the unused period of the product, specific operation methods are as follows:

No.	Time (H)	Dehumidification Steps
1	At 0-2 hours	leave the screen in a black state to warm up
2	At 2-4 hours	Level 30 grayscale aging
3	At 4-6 hours	Level 60 grayscale aging
4	At 6-9 hours	Level 90 grayscale aging
5	At 9-12 hours	Level 150 grayscale aging

PS: Reduce or extend the aging time according to the actual usage environment, climate and shutdown time.
