small but even more powerful
Biemme italia present a panel HMI 4.3 rooted, android 5.1 technologies with outputs on board.
His name is Ltouch43.
Stainless steel frontal frame and stainless steel rear cover !
Thanks to the free development Android Studio you can create your own personalized app.
Graphics and Logics all in the same IDE.
Android 5.1 and its many functions allow you to connect with the worlds. In order to leverage the flexibility of the Android OS, the board has a native modus RTU library for Android that is able to communicate with every device through RS485.
Android 5.1 rooted
much faster in thread management
use it for IOT projects
lower absorption current
The product will comes with a free Android modbus library that can be used to communicate with any commercial products such as PLC, I/O modules, temperature controllers and in general with any device that support the modbus protocol through rs485.
RS485 full isolated
We developed our own library to support hardware I/O in all Android projects; it is reliable, fast in terms of execution time and open source . It is simple to import our library in eclipse projects and write your (java) project to handle I/O
RS485 it is polarized, so as to allow communication over long distances,
all RELAY outputs are protected by varistors, high quality relay, output: 24VDC max 5A, 250V max 5A
all connectors are removable
RED signaling LED for power supply anomaly
GREEN signaling LED for voltage presence
If a board is connected to a network via Ethernet before it is powered on it will automatically obtain an IP with DHCP activated after it is powered up. If you want to set up a static IP you can use the user interface or modify the kernel
Stay connected from anywhere
On board there is a module low-power consumption module which has all of the WiFi, Bluetooth. With seamless roaming capabilities and advanced
security, also could interact with different vendors’ 802.11b/g/n Access Points in the wireless LAN.
The wireless module complies with IEEE 802.11 b/g/n standard and it can achieve up to a speed of 72.2Mbps with single stream in 802.11n draft, 54Mbps as specified in IEEE 802.11g, or 11Mbps for IEEE 802.11b to connect to the wireless LAN.
Electrical noises. The most important rules
Maximization of PCB Ground area
Functional grouping of components for EMI control
Optoisolated RS485 Line
Short tracks for limiting radiation and crosstalk issues
Analog inputs far from noise sources
Capacitors split for removing any high frequency noises
There are no limits for Ltouch43
Possibility to implement a server inside the Ltouch43 with which any wifi device can exchange information.
Just connect to the Ltouch43 network generated with hotspots.
Ltouch43 is rooted
This application starts automatically when the device starts.
We have created a series of settings to adapt it to all situations. Some of the settings
-p Password to access server
-e Path to encrypted password file to access server
-r Screen rotation (degrees) (0,90,180,270)
-s Scale percentage (20,30,50,100,150)
-z Rotate display 180 (for zte compatibility)
Upload all the projects you want, just use what you need
You can have all your projects contained within Ltouch43, only when you need and without any external device you can choose the app that is right for you.
let the operator choose
install your app in your smartphone and show your work to the customer.
You can securely connect to a remote computer or server using a text-based interface.
When a secure SSH connection is established, a shell session will be started and it will be possible to manipulate the server by typing commands within the client on the local computer.
we can install the SSH server inside the touch
Power Supply Voltage Recognition
The hardware architecture recognizes the supply voltage when there is a difference of 20% Ltouch43 and turns off.
4 power relays installed directly in the Ltouch43. Thanks to the library you can easily use the outputs on board
