1. What could be the reasons for not loading?
The loading failure may be caused by the following reasons, please compare with your operation according to the listed items:
A. Ensure that the control system hardware is powered on correctly. (+ 5V)
B. Check and confirm that the serial cable used to connect the controller is a straight-through cable, not a crossover cable.
C. Check and confirm that the serial port connection cable is intact and there is no loosening or falling off at both ends.
D. Select the correct product model, correct transmission method, correct serial port number, correct baud rate according to the control software and the control card you choose, and set the address on the control system hardware correctly according to the dial switch diagram provided in the software Bit and baud rate.
E. Check whether the jumper cap is loose or detached; if the jumper cap is not loose, make sure that the jumper cap is in the correct direction.
F. If you still can't load after the above check and correction, please use a multimeter to measure whether the serial port of the connected computer or control system hardware is damaged. To confirm whether the computer manufacturer should be returned or the control system hardware should be returned for testing.
2. What could be the reason for the communication failure?
The reason for not communicating and loading is probably the same. It may be caused by the following reasons, please compare with your operation according to the listed items:
A. Ensure that the control system hardware is powered on correctly. (+ 5V)
B. Check and confirm that the serial cable used to connect the controller is a straight-through cable, not a crossover cable.
C. Check and confirm that the serial port connection cable is intact and there is no loosening or falling off at both ends.
D. Select the correct product model, correct transmission method, correct serial port number, correct baud rate according to the control software and the control card you choose, and set the address on the control system hardware correctly according to the DIP switch diagram provided in the software. Bit and baud rate.
E. Check whether the jumper cap is loose or detached; if the jumper cap is not loose, make sure that the jumper cap is in the correct direction.
F. If you still can't load after the above check and correction, please use a multimeter to measure whether the serial port of the connected computer or control system hardware is damaged. To confirm whether the computer manufacturer should be returned or the control system hardware should be returned for testing.
3． Why does the system prompt 'Please connect the controller'?
Many customers and friends directly download the 'control system' from the 'Download Center' on the company's website. After installation and running for 20 minutes, the prompt 'Please connect the controller' will appear. This is because the system did not The cause of the hardware of the control system was detected.
At this time, please connect one end of the control system hardware you have purchased to the computer and the other end to the HUB distribution board. The cable socket of the HUB distribution board is connected to the interface of each unit part.
After the connection is completed, you can enter the 'Setting Screen Parameters' in 'Settings' to set the relevant parameters. Close and reopen the software after completion. At this time, the word 'Connection succeeded' will appear at the top of the software. At this point, the system has detected the hardware of the display control system and can be used normally without time limit.
4． What does automatic or manual brightness adjustment mean? Brightness adjustment refers to the adjustment between the darkest and brightest that the display can show. Instead of sensitivity adjustment.
Automatic brightness adjustment is based on the different brightness that should appear in different time periods, and is automatically adjusted to a certain predetermined brightness by the wide control system.
Manual brightness adjustment refers to that the end user achieves a certain brightness through the operation of the control system.
