How to cascade the led display 2 sending cards

1. Hardware preparation.

1. A DVI line (a line where one end of the DVI line turns to two ends).

Zhang Ling Xingyu 802 sending card.

3. A ten-needle line.

2. Hardware connection.

Figure 1 Connecting two sending cards with a 10-pin cable.

Figure 2 Key settings.

3. Insert the two sending cards into the PCI socket of the computer, connect the DVI of the graphics card with the two sending cards with the DVI one-to-two cable, insert the DVI port of the graphics card at one end, and insert the DVI port of the two sending cards into the two ends respectively. See Figure 3.

Figure 3: Connect the DVI interface of the two sending cards.

3. Software settings.

After the cascading of the two 802 sending cards, it can be brought to a maximum of 1600*1200 pixels, and the two sending cards have a total of four RJ45 signal output ports, which are 1U1D2U2D, as shown in Figure 4. The RJ45 of the sending card with the unchanged red button is 1U1D, and the RJ45 of the other sending card is 2U2D

Figure 4 Relationship between the output ports after the two cards are cascaded.

When operating the CON file, set it according to the connection method of the screen, because the RJ45 of each sending card has a height of 400 points, and if it is higher than 400 points, use another RJ45 port, so as to push it up, starting from the 1U port, 1U-1D-2U-2D, and setting the CON file as follows.

The specific method is set according to the on-site connection method, and after the setting is completed, it will be sent to the receiving card and saved to the receiving card.

In addition, there are many products on the group IDC network**, which are cheap and have a good reputation.

There are switches on the card, one to 1 and one to 2.

LED display: A flat panel display that consists of small LED module panels.

LED, Light Emitting Diode (Light Emitting Diode abbreviation). It is a display method that controls semiconductor light-emitting diodes, and diodes made of compounds of gallium (Ga) and arsenic (As), phosphorus (P), nitrogen (N), and indium (In) can emit visible light when electrons and holes are recombined, so they can be used to make light-emitting diodes. It can be used as an indicator light in circuits and instruments, or as a text or digital display.

GaAs diodes glow red, GaN diodes glow green, silicon carbide diodes glow yellow, and indium gallium nitrogen diodes glow blue.

Cascade refers to a series of single-line reply messages, where each message is a reply to the previous message, and contains the most recent changes to all the previous packets, and each line is preceded by a news reader's delivery command with an improperly shortened "" (sometimes other characters) to indicate the 6, cc of the previous message.

Cascade also refers to the design of one-to-many relationships. For example, a table stores the teacher's information: Table A (name, gender, age), and the name is the primary key.

There is also a table that holds information about the class the teacher is teaching: Table B (name, class). They cascade by name.

Cascading operations include cascade update, cascade delete. When you enable a cascading update option, you can change a primary key value if a matching foreign key value exists. All matching foreign key values are updated accordingly.

If the record with the name Zhang San is changed to Li 4 in Table A, then all the records with the name Zhang San in Table B will also be changed to Li 4. Cascading deletions are similar to updates. If you delete a record with the name Zhang San in Table A, all records with the name Zhang San in Table B will also be deleted.

Video processors can do it.

You can try it directly from your computer.

There are switches on the card, one to 1 and one to 2.

LED sending card is a control card software, which converts and transmits the audio signal of the computer to the LED display, also known as the control system. The LED display Yuli screen sending card is to package the image information and send it to the receiving card, and the receiving card is unpacked for image processing. The control area of each receiving card is a certain amount, which is related to pixels.

The LED display screen has the instructions from the computer control software, so it is necessary to have a receiving card to decode the received instructions, and then control the light and off of different LEDs.

There are many sending cards, what card do you have?
