●Support three configuration method: serial AT command, PC software and web page
●Support local firmware upgrade by PC software
●Support “Keep-Alive” to guarantee TCP connection
●Support user password authorization for security
Industrial temperature range (-40℃~+85℃)

Basic Function

ED2 can realize two-way data transmission between TTL UART and Ethernet,
3 UART ports work independently at the same time, without mutual influence.

Block Diagram

Multiple Working Modes

ED2 supports five working modes: TCP Client, TCP Server, UDP Client,
UDP Server, and HTTP Client, which can be flexibly
selected according to the usage scenario.

Hardware Watchdog Protection

Built-in hardware watchdog, stable
operation for 24 hours without downtime.

Configuration Software Upgrade

Parameters can be configured across network segments, the page is
more concise.The firmware can be upgraded directly through the
built-in webpage, which is convenient and quick.

Modbus gateway

Support Modbus RTU and Modbus TCP protocol conversion
Support Modbus multi-host polling
