E103-W02DTU is a UART-WIFI server supporting RS232/RS485 to WIFI two-way transparent transmission. It enables the UART device to immediately have TCP/IP network interface function, which extends the operation range of the device.
E103-W02DTU is developed based on the TICC3200, users could select RS232 or RS485 interface to communicate. This UART server is a transparent transmission server for network access through UART by AT command.
E103-W02DTU supports standard IEEE802.11b/g/n protocol and complete TCP/IP protocol stack, supports STA/AP mode, supports Smart Config, UART transparent transmission, transparent transmission on power-up, etc. Network connection can be achieved after easy configuration.
It supports both RS232 and RS485
Configuration through webpage
The user can access the server through webpage to read and configure the parameters
Transparent transmission on power-up
The server can automatically connect to WIFI network upon power-up and connect with target server with transport protocol.
In STATION mode, the server will automatically reconnect the lost connection.
The user can use SmartConfig to connect network and configure the server quickly.
Remote AT command
The module supports remote AT command for easily configuring parameters.
