01. Do not load on what may be the cause?
Do not load may be due to several reasons, listed according to the operation of your control:
A. To ensure that the control system hardware has the right power-on. (+5 V)
B. Check to make sure the controller's serial port to connect straight line for line, and not cross lines.
C. Check to make sure the serial port to connect both ends of the line intact and not loose or fell off the phenomenon.
D. LED display control software to control their own choice and control cards to choose the right product model, the correct way of transmission, the correct serial number, baud rate and the right software to provide control of dial code switch plans to set up the correct control system hardware The address of the place and the baud rate.
E. To see whether the jumper cap off or loose; If the jumper cap is not loose, make sure the jumper cap on the right track.
F. If, after checking the above and after the correction still does not load, please use measurement multimeter if this is connected to the computer control system or the hardware serial port were damaged. To confirm whether or not to return or computer manufacturers will return control system hardware detection.

02. Communications may not be what causes?
Communication is not loaded with no more or less the same reasons, may be due to several reasons, listed according to the operation of your control:
A. To ensure that the control system hardware has the right power-on. (+5 V)
B. Check to make sure the controller's serial port to connect straight line for line, and not cross lines.
C. Check to make sure the serial port to connect both ends of the line intact and not loose or fell off the phenomenon.
D. LED display control software to control their own choice and control cards to choose the right product model, the correct way of transmission, the correct serial number, baud rate and the right software to provide control of dial code switch plans to set up the correct control system hardware The address of the place and the baud rate.

To confirm whether or not to return or computer manufacturers will return control system hardware detection.

03. Why will be prompted to "connect LED display controller"?
A lot of friends from the customer's site on the "Download Center" to download directly to be "LED display control system", after the installation of running after 20 minutes there will be "connected LED display controller" tips, this is due to the system In the test of time not detected go wide control system hardware of the reason.
At this point, I would be grateful if you purchased the LED screen at one end of the control system hardware and computer connected to the other side of the plate connected with the HUB distribution, HUB distribution panels and cable outlet LED display unit in all parts of the interface is connected.
After connecting, you can enter the "settings" in the "screen set parameters," the provision of the relevant parameters, after the completion of the re-closure of the open software, this time, the software will appear at the top of the "connected". At this point, the system has been detected screen control system hardware can be no time limits to the use of the normal.

04. Why LED display control system hardware at the power-on time there will be a few seconds or a bright line "Hua Ping"?
And the computer will display controller HUB and the distribution of display panels and connect properly, the need to provide +5 V power supply controller in order to make it work (at this time, not directly connected with the voltage 220V). Instant power-on, the screen will appear a few seconds or a bright line "Hua Ping", the bright line or "Hua Ping" tests are normal, to remind the user display is about to begin work.
2 seconds, the automatic elimination of the phenomenon, the display into the normal working condition.

05. Automatically or manually adjust the brightness What does this mean?
Light regulation is the best display in the show's most dark and the brightest among the adjustments made. Rather than adjust sensitive.
Automatic brightness adjustment is based on a different time period appears to be different from the brightness and go wide LED screen control system to automatically adjust the brightness of a target.
Manually adjust the brightness refers to the end users go through the wide LED screen control system operated by the LED display to reach a specified brightness.

06. Why all the normal controller when there is no display screen above?
Controller and set up cable to connect properly, sometimes LED display will also appear on the screen does not show, usually caused by one of the reasons, please check:
A. LED display is the normal power-on.
B. HUB distribution panels and display anti-access connection is.
C. The editor of the program and send it to air.

07. Unit does not screen the entire board appears bright, light dark.
A. Visual power cable, cell plate 26P cable between the power module and light are in working order.
B. Multimeter measured by whether or not the normal cell plate voltage, and then measuring the output voltage power supply modules are in working order, and if not, what is judged as a bad power supply module.
C. Measurement of low-voltage power supply modules, fine-tuning adjustment (power module close to the Office of the fine-tuning light) so that the voltage is up to standard.

08. LED display is a black screen appears, what causes?
In the application of control systems, we occasionally encounter LED screen appear black. The same phenomenon may be caused by a variety of reasons, even the black screen of the course will be different as a result of the operation or because of different circumstances vary. For example, it may be a power-on moment is black, also in the process of loading in the black, but also may be sent in after dark, and so on. Please note that this encounter could be in the light of the following to determine all aspects of the "failure":
A. Please ensure that the control system, including all the hardware has all the right power-on. (+5 V, not to take anti-, followed by mistake)
B. Inspection and confirmed again and again to connect the controller serial line if there is loose or fell off. (If in the process of loading in the black, it may be due to the reasons, that is, in the process of communication due to the interruption of communication lines and the loose, and therefore screen. Do not think that no-screen action, the line can not be relaxed, Hands-on look, which you want to solve the problem quickly is important.)
C. Check to make sure to connect with the LED display and the main control card connected to the distribution of the HUB's board is closely connected, whether or not the anti-inserted.

E. To see whether the jumper cap off or loose; If the jumper cap is not loose, make sure the jumper cap on the right track.
