LED electronic display common problems

 

 

01. Can't load may be what reason is caused? Can't load may be caused by the following reasons, please listed according to the contrast with your operating:

 

A. to ensure that the hardware of control system has the correct access to electricity. (+ 5 v)

 

B. check and make sure the serial port used to connect to controller for straight line, not cross line.

 

C. check and confirm the serial ports on both ends of the cable is in good condition and no loose or falls off phenomenon.

 

D. contrast control software and control card of their selection to choose the right product model, the right of transmission mode, the correct serial number, the correct baud rate and software available to dial the code switch figure set correctly on the control system hardware address and the baud rate.

 

E. check the jumper cap is loose or fall off; If the jumper cap without loose phenomenon, please make sure the jumper cap in the right direction.

 

F. if there is still a loaded after the above check and correction, please use multimeter measure, connected by the computer or the control system hardware serial port is damaged. To confirm whether they should get back the computer control system hardware return detection or manufacturer.

 

02. Communication is not on what could be the cause?

 

With load on communication is not no reason is roughly same, may be due to several reasons for this, please listed according to the contrast with your operating:

 

A. to ensure that the hardware of control system has the correct access to electricity. (+ 5 v)

 

B. check and make sure the serial port used to connect to controller for straight line, not cross line.

 

C. check and confirm the serial ports on both ends of the cable is in good condition and no loose or falls off phenomenon.

 

D. contrast control software and control card of their selection to choose the right product model, the right of transmission mode, the correct serial number, the correct baud rate and software available to dial the code switch figure set correctly on the control system hardware address and the baud rate.

 

E. check the jumper cap is loose or fall off; If the jumper cap without loose phenomenon, please make sure the jumper cap in the right direction.

 

F. if there is still a loaded after the above check and correction, please use multimeter measure, connected by the computer or the control system hardware serial port is damaged. To confirm whether they should get back the computer control system hardware return detection or manufacturer.

 

3. Why the system will prompt the wording "please connect the controller"?

 

Many customers friend from the company website "download center" direct download to get the "control system", after the installation is run after 20 minutes will be appeared with the words "please connect the controller", this is because the system was not detected in the test of time seems notions of width control system hardware.

 

At this time, please will you buy one end of the control system hardware is connected to a computer, the other end connected to the HUB distribution board, the HUB of distribution board wiring plug connected to every unit of part of the interface.

 

After the connection, then enter the "Settings" in "Settings screen and set up the relevant parameters, closed again after the completion of open software, at this time, the software will appear above the wording" connection is successful ". At this point, the system has detected display control system hardware, can be normal use without a time limit.

 

04. Why control system hardware for a few seconds in the first power on light lines or "flower screen"?

 

Will display controller connected to the distribution of computers and the HUB board and the display screen is in order, the need to provide the controller + 5 v power supply to make it work properly (at this point, do not directly connected to 220 v voltage). The electric instant, the screen will appear a few seconds of bright lines or "flower screen", the bright line or "flower screen" is the phenomenon of normal test, to alert users to display screen is about to start work.

 

2 seconds, automatically eliminate the phenomenon, screen into the normal working condition.

 

05. Automatic or manual brightness adjustment is what mean? Brightness control refers to the display screen can display between the darkest and brightest make adjustments. Rather than light regulation.

 

Automatic brightness adjustment according to the different time periods are different brightness and should appear from notions of width control system automatically adjusts to a scheduled brightness.

 

Manual brightness adjustment refers to the end users through to the notions of the operation of control system to achieve a specified brightness.

 

6. Why the controller display screen are not shown above when everything is all right?

 

Controller under the condition of setting and connected properly, without is sometimes also can appear on screen display, is usually caused by one of the following reasons, contrast, please check:

 

A. if there is something wrong with electricity.

 

B.H UB attachment whether meet the distribution board with display screen.

 

C. the edit and send program for null.

 

07. Unit board in the whole screen is not bright, dark bright.

 

A. visual power cables, cell plate between 26 p ribbon cable and power supply module indicator light is normal.

 

B. the multimeter measurement unit plate with and without normal voltage, measuring the output voltage power supply module is normal again, if no, is bad judgment for the power module.

 

C. measure the low voltage power supply module, regulate the fine-tuning fine-tuning (near the lamp power supply module) make voltage up to standard.

 

08 appears black screen is what reason is caused? In control system used in the process, we occasionally meet, the phenomenon of the black screen. The same kind of phenomenon may be caused by different reasons, even display blackening process will vary with different operating or because of the different environment. Such as it may be a moment of electricity is black, may also be black in the loading process, also may be black, and so on. After sent met please note that this phenomenon may refer to the following aspects to judge "failure" :

 

A. please make sure that all hardware, including control system, has fully correct electricity. (+ 5 v, don't pick up the, wrong)

 

B. check and double-check the serial port of the used to connect to the controller for loose or falls off phenomenon. (if the black in the loading process, probably because the reason is caused, namely in the process of communication was interrupted because of loose communication line, so the screen black. Don't think that display body did not move, the line can not be loose, please to check, it is important for you want to quickly solve the problem.)

 

C. check and confirm the connection and the distribution of the HUB board connected to the master card is close connections, whether against
