1. Observe the signal indicator of Hitec touch screen, the light flashes regularly under normal circumstances, about once per second, when touching the screen, the signal light is always on, and after stopping the touch, the signal light resumes flashing.

2. If the signal light is still on when there is no touch, first check whether the touch screen needs to be cleaned; Secondly, check whether the serial slogan connected to the hardware is consistent with the serial slogan set by the software, and whether the serial port of the computer host is working normally.

3. Run the COMDUMP command in the driver disk, the command is a DOS command, add a space and the code 1 or 2 of the serial port after the COMDUMP when running, and touch the screen to see if there is any data rolled out. If data is rolled out, the hardware connection is normal, check whether the software settings are correct and whether there are conflicts with other hardware devices. If there is no data rollover, the hardware will fail, and the specific fault point is to be determined.

4. Run the SAWDUMP command in the drive disk, the command is a DOS command, when running the program, the program will ask for the type of control card, the port number of the connection, and the transmission rate, and then the program will read the relevant data from the control card. Please note that if the AGC value of the X axis and the AGC value of the Y axis are in the lower left corner of the screen, if the value of either axis is 255, the transducer of that axis will fail and needs to be repaired.

5. After installing the driver, pay attention to the details of the system error. "No control card found", "Hitec touch screen is not connected", etc., check the corresponding parts according to the prompts. For example, whether the touch screen signal cable is firmly connected with the control card, whether the keyboard cable is all connected to the host, etc.

6. If it still cannot be ruled out, please ask a professional for maintenance.
