21.5′′ Touch Passenger Elevator Display for Otis

Brief introductionTouch LCD is a car touch COP, including floor touch buttons, elevator floors, elevator status, full view of warning information and HD display. This LCD is easy to install and easy to use. It can be embedded to be installed on COP.Performance index Working temperature:  -10~70ºC Storage Temperature: -20~80ºC Relative humidity:  95% 40ºCElectric Spec Input voltage                   DC20~60V Consumed power                19.92W(21.5) CPU Clock Speed               Cortex™-A9 1000MHz ROM space            4GB DDR3(The maximum can be extended to 64GB) RAM space            1GB(The maximum can be extended to 2GB) USB interface          USB2.0*3(Two terminals and a pin) LVDS interface         2ch/24bit*1 1920*1080(MAX) HDMI interface         24bit1920*1080(MAX) I2C                  1*2 Audio                One Audio Line out L and one Audio Line out R  Ethernet              10M/100M*1(RJ45 with indicator)Human-Computer Interaction      Support mouse, keyboard, touch screenVideo Format           mpeg4,*.mp4Operating system        Android 4.3   Structure sizeScreen specification  21.5"Overall dimension   21.5 350*650*28(mm)Display dimension   21.5 268*476(mm)Display parametersResolution        1920*1080Screen Ratio       16:9Luminance        250cd/m2Contrast ratio      5000:1Color            16.7M Visual angle (horizontal / vertical)        178°/178°Response time(ms)                  6msThe minimum diameter of touch objects    6.5mmCommunication interface protocol 4PIN port pin:1234The definition of input signal :+30VGNDClockData Product function   Elevator floor selection button functionOpen and close door button functionCOP current floor displayElevator warning information display, such as fire, overloading information tips, no smoking tipsProvide two interface display styles which can be set up in the configuration interfaceDisplay date, time, lift load on the interfaceFloor guidance information can be setProvide two ways to replace the display contentsInsert only U disk into the device to automatically updateProduct function diagram  Chapter 2Installation instruction    Touch outline dimensions and installation drawings  RS32 board outline dimensions and installation drawings  Installation diagram (1):The elevator panel opening and screw holes (4):On the back of the panel,use screws to lock the display  Embedded installation steps (2):The display is directly inserted into the panel from the front face of the panel (3):Fully embedded, bottom fit    Chapter 3The working conditions and environmental requirements  1. The connection and disconnection of any cable must be carried out under power failure.   2. The connection of the cable must be firm and anti-seismic.    3. Try to keep the LCD away from the strong electromagnetic environment(except 220VAC).    4. Keep the working environment of the LCD dry, ventilated and without strong magnetic radiation.    5. The stabilized voltage supply input remains constant(AC220V).    6. The maintenance system needs to connect to the network(Choose one of LAN,WIFI,4G).    7. The rated working voltage of LCD and RS32 communication board shall be within the range of DC24V to DC40V;    8. When connecting the power supply plug, please pay attention to the direction of the socket and do not install anti.    9. During the installation process of RS32 board, it should avoid falling, collision to prevent damage to components;    10. When installing the RS32 board, be careful not to cause serious deformation of the circuit board to prevent damage to the components.    11. The RS32 board must be protected against static electricity when it is installed;    12. In normal use, it should avoid short circuit caused by the collision from metal shell and other conductive objects and even can burn the circuit;     /* March 10, 2023 17:59:20 */!function(){function s(e,r){var a,o={};try{e&&e.split(",").forEach(function(e,t){e&&(a=e.match(/(.*?):(.*)$/))&&1
