EW10/EW11


RS232/RS485 to WIFI Serial Convertor



EW10/EW11

RS232/RS485 to WIFI Serial Convertor

 

 


 

 

The EW10/EW11 module provides RS232/RS485 interface to Wi-Fi connectivity. The module integrates a TCP/IP controller, memory, high-speed serial port, a fully developed TCP/IP network stack, and mbed OS. The EW10/EW11 also supports remotely configuration & monitoring with IOT Service.

The EW10/EW11 module is a complete solution for serial port device connecting to network. This powerful device supports a reliable and proven operating system stored in flash memory, an embedded web server, a full TCP/IP protocol stack, and standards-based (AES) encryption.

The module can work in 4 modes: TCP Server, TCP Client, UDP Server, and UDP Client.

The Elfin-EW1X integrates all serial to Wi-Fi functionality with 61 x 26 x 17.8mm size.

RS232 Interface

Device RS232 does not support hardware flow control. The physical voltage is about ±7V.

 

 

 

 

 

RS485 Interface

RS485 use two wire links, A(DATA+), B(DATA-). Connect A+ to A+, B- to B- for communication. You might need to connect GND together when interference is very severe.

The RS485 interface support maximum 32 devices. The cable maximum length is 1200 meters. Need to add 120Ohm terminal resistor for over 300 meters.
