Communication interface: for the Q series of CPU''s built-in bus connection interface F940GOT-LWD-C. The first characteristic of touch screen: Transparent, it directly affects the visual effect of touch screen F940GOT-LWD-C The problem of transparency is the degree of transparency, infrared technology, touch screen and surface acoustic wave touch screen is separated by a layer of pure glass, Transparency can be considered a leader, the other touch screen this is a good scrutiny, transparency", The touch screen industry, is a very broad concept, many touch screen is a multilayer composite film, It''s not enough to generalize its visual effect with only a little transparency, It should include at least four characteristics: transparency, color distortion, reflection and clarity, but also, For example, the degree of reflection, including the degree of specular reflection and diffraction, But the touch screen surface diffraction reflection has not reached the extent of the CD disk, For users, these four metrics are basically enough F940GOT-LWD-C F940GOT-LWD-C. "RS-422/485 serial communication unit (D-sub9 pin (header). Applicable models: GT15, GT16, GT27, GT25. Function: high performance and low price in the middle end model. Picture size: 10.4 inches. Resolution: VGA. Display: TFT color. Open frame type. Panel color: white. Power type: DC24V. Middle end model of high performance and low price. GT25 standard supports SD memory card and standard equipped with Ethernet, RS-232, RS-422/485, host/device USB interface. Even in the log, script, alarm, soft component data transmission, such as high load processing period, but also to achieve smooth operation of the screen. Connect GOT front USB interface and computer, Can be through the FA, the GOT machine programming, start and adjust the operation, Save the trouble of opening the control cabinet and changing the cable.
