1. The power cord is not properly connected This may seem obvious, but make sure the power cord is connected to the back of the touchscreen and plugged into a power outlet. If it looks like it's connected correctly, disconnect and reconnect both ends of the power cord to make sure the cable isn't loose. 2. The power cord is damaged ...

Virtual serial port configuration process: 1. Open the virtual serial port configuration software and create two pairs of serial ports; 2. The circle is the physical serial port in the computer, and the virtual serial port in the box; 3. Two groups have been added, and friends who want to add port tests can do so in the window on the right.

Since the launch of the cMT-SVR, the innovative body and screen separation architecture has subverted the market's imagination of HMI. With the continuous cultivation of Weiluntong, this unique detached HMI has gradually gained a foothold in the market and is now widely used in the market. 　　In order to meet the needs of the new generation of industrial Internet of Things ...

(1) FILM - that is, the film used for touch, the base material is PET. When touched, the ITO of the upper and lower layers is brought into contact by deforming the film, resulting in different "resistance values" in the X and Y axes (similar to the principle of moving rheostats). Depending on the requirements of use, the table of FILM ...

1. Check whether the power supply of the host is working normally. First, check whether the host system is powered by checking whether the power indicator on the host chassis panel is on and whether the power supply fan is rotating. Secondly, use a multimeter to check whether the external voltage meets the requirements, the voltage is too high or too ...

The parameters of the touch screen to characterize the characteristics of the capacitor include the loss factor D value, the figure of merit Q, the series equivalent resistance ESR, etc., the essence is the same, take a parameter to know the quality of the capacitor, but take the loss factor D value reference meaning. These parameters are usually not possible with a digital bridge.

1. The optical performance is the best. The clarity and light transmittance are the highest, the reflection is the least, and there is no color distortion, this is because the sound wave screen body is pure glass, unlike the resistive screen with multiple layers of composite film; The capacitive screen is coated with a layer of film on the surface, and the light transmittance is worse. 2. Anti-scratch and anti-barbaric use ...
