Recently, I have received inquiries from several customers: "Is this sending card installed inside or outside the screen? "To be honest, if this thing is installed in the wrong position, the entire screen may become bricked! Today we broke up and broke it and talked about the correct way to set up a home for the sending card.

1. The sending card is not a USB flash drive, the location is very particular

​​1. Regular installation of gold​​
90% of the large LED screens hide the sending card in the right back waist. Just like the SIM card slot of the mobile phone has a fixed position,​ ​When standing facing the display, the groove area on the back of the box on the right hand side​ ​It is the standard installation position. Here is close to the control card, the signal line is the shortest, which can reduce signal interference by more than 30%.

​​2. Transformation of special scenes​​
What should I do if I encounter a curved screen or a special structure? When installing a curved advertising screen in Singapore last year, the engineer moved the sending card to the top beam. ​ ​Key Principles​ ​: No more than 5 meters away from the receiving card, avoid strong electromagnetic interference sources (such as air conditioning units).

3. Installation steps to prevent overturning guide

1. ​​Find the positioning hole before unboxing​ ​: There are usually 3 M8 screw holes on the back of the box, arranged in a triangle shape
2. ​​Don't use brute force​ ​: Install the DVI port fixing screw first, and then lock the PCI blank
3. ​​The cable should be serpentine​ ​: Referring to a Tokyo Stadium plan, the cable bending radius ≥5cm can extend the life span by 30%

​​Important Tips​ ​: When plugging in the 4-pin power supply interface, smoke will come out! The correct posture is to align the plug groove with the bulge.

4. Life and death line of heat dissipation and ventilation

1. ​​Leave 3cm up and down​ ​: Last year, the Seoul transparent screen card burning accident was caused by wall installation
2. ​​Ambient temperature should not exceed 40℃​ ​: The sending card with intelligent temperature control can automatically reduce frequency and save life
3. ​​Regular cleaning schedule​​：

   Usage environment	Cleanup cycle
   Indoor shopping mall	12 months
   Outdoor construction site	3 months
   Stage rental	Every time

5. Lightning protection in high-incidence areas

1. ​​Signal interface oxidation​ ​: When the humidity in the rainy season is > 80%, special anti-oxidation paste should be applied to the interface
2. ​​Electrostatic breakdown​ ​: Be sure to wear anti-static bracelets before installation in dry areas in the north
3. ​​Electromagnetic interference​ ​: Stay away from the inverter and high-power motor at least 2 meters

There is a real case: a certain landmark screen frequently flies the screen, and finally it is found that a 5G base station is installed next to the sending card. Later, the metal shield was installed to solve the problem.

To be honest, the sending card is like a person's heart. Only when the position is placed correctly can the qi and blood flow smoothly. I have seen too many customers messing around in order to save space, and the repair fee is even more expensive than the screen. When choosing equipment, you have to choose a large factory with a monthly output of over 10,000 square meters. There are 18 processes in the production base in Bao'an District alone. The sending card made by this process is easy to install anywhere!
