Safely connecting LED Video wall modules is one of the most important things to keep in mind by the owner or installer. It might be difficult for some; that’s why we will help and guide you by providing you the essential steps in doing so in this post.

LED video wall module connection is effortless. It only takes nine steps as below:

  1. Connect 220(110) voltage main power cable to the power supply;
  2. One power supply to the next;
  3. Five voltage power cables to the power supply;
  4. Flat cable to the receiving card;
  5. Power cable to the receiving card;
  6. One receiving-card to the next;
  7. Power cable to the LED module power interface;
  8. Flat cable to the LED module signal interface;
  9. Connect Novastar sending box (card) between laptop (PC) and receiving card.

LED video wall module connection needs items as below.

LED-Video-Wall-Module-Connection- 1

  • LED Module;
  • Sending Box (MCTRL300);
  • Receiving-card (MRV336);
  • Power Supply (G Energy);
  • 220V AC Input Power Cable;
  • 220V AC Power Cables;
  • Cat6 Cable;
  • 5V DC Power Cable;
  • Laptop;
  • Ribbon Cable; and
  • Screwdriver.

Connect all items from one to another in a proper way. And to make each step more straightforward for you, let us walk you through the process following the outline below.

  • Power supply input interface

The power supply input voltage is 220(110) voltage. There are three marks in the power supply input port: L, N, and G. L stands for Live, N stands for Neutral, and G represents Ground.

  • 220 (110) V AC power cable interface

The 220/110 voltage main power cable has three wires in three different colors. The brown color is a live wire; the Blue color is the neutral wire; the Yellow and Green color is a ground wire.

Make sure that all connection is incorrect. Each interface: live to live, neutral to neutral, ground to ground. Suppose Blue color wire connects to the L interface, the power supply will burn.

In Jonas’s demo video, you can see that he is using a G energy power supply. But if you are using Meanwell, Chuanglian, VAT, etc. Power supply, connection way is same.


2. Connecting one power supply to the next

The power cables connecting two pieces of the power supply are 220(110) voltage. Make sure that the power supply wire connection is correct.

Every interface: live to live, neutral to neutral, ground to ground. You could check detailed information in step 1.


3. Connecting five voltage power cables to the power supply

  • Power supply output interface

The power supply output is 5V DC to LED module. V+ represents live wire, and V- stands for the neutral wire.

  • 5V DC power cable interface

In the LED screen industry, the 5V DC power cable is short named Red and Black cable. Red wire stands for live wire, and black wire stands for neutral wire.

Make sure that all 5V DC power cable connection is in a correct interface: live to live, neutral to neutral. Otherwise, a wrong link will burn LED module driver IC. And it will damage or burn the receiving-card IC as well.


4. Connecting the flat cable to receiving-card

You should know the serial numbers JH1~JH12 next to each interface in the MRV336 receiving card. And be sure that flat cables connecting in order of 1-12.

Suppose there was a mistake plug order. You will fail to complete an intelligent screen setup or RCFG file upload.


5. Connecting the power cable to the receiving-card

  • Receiving-card input power interface

You will find two power ports on the receiving card. The one close to Lan port marked GND means neutral port, the other one marked 5V is live port.

  • 5V DC power cable interface

The 5V DC power cable, red wire stands for live wire, and black wire stands for the neutral wire.

Ensure that the red wire connects to the 5V port; the black wire connects to the GND port. If there was a wrong connection, the receiving card can not work or damage the receiving card.


6. Connecting one receiving card to the next

You can plug the RJ45 cable into any port in the MRV336 receiving card. Each port in each receiving card can be input and output.


7. Connecting power cable to the LED module power interface

You will find it’s easy and fast to connect the power cable to the LED module. As both interfaces have a buckle design.

Make sure that you can plug the power cable quickly and smoothly. Otherwise, it’s in a reverse direction; turn to another side and fill again.


8. Connecting flat cable to the LED module signal interface

From the module back view, connect the JH1 port to the right up the module. Then JH2 port to the left up the module, JH3 port to the right down module, JH4 port to the left down module.

Make sure that your connection order is correct. The wrong connection order will misplace the display picture.


9. Connecting Novastar sending box between laptop and receiving-card

  • First, connect the power cable to sending package MCTRL300
  • Then, click the USB cable between MCTRL300 and Laptop
  • Afterward, connect DVI port to MCTRL300, and HDMI port to Laptop
  • Connect Lan to MCTRL300 and MRV336 receiving-card

Either OUT1 or OUT2 in MCTRL300 is fine. Meanwhile, you can plug RJ45 to U or D port in MRV336 receiving-card; both can work as input and output.

Above all, it’s easy to connect an LED video wall module. You might have a P10 LED module or any other LED module sizes; the LED module connection method is the same.
