USR-TCP232-E2 is an embedded TCP/IP module provide solutions to build serial to ethernet connectivity while also controlling your serial device and make data tramission. This article is to introduce ethernet module USR-TCP232-E2:

 

To realize two-way transparent transmission between COM and TCP/IP,manage COM on remote device over network.

To communicate to multiple serial devices at the same time across a LAN or WAN network.

UART to Ethernet

The global unique MAC address bought from IEEE, defined MAC address is available

Virtual COM ports connect PC/servers to remote serial devices over Ethernet

Hardware flow control RTS/CTS

Modbus TCP to Modbus RTU, work as slave

httpsD Client and Websocket function available

Up to 8 simultaneous clients when act as TCP Server

Support DNS & DHCP, automatically access IP

Two TTL interface can be worked at one time

Reload button, a key restore default Settings

With network transformer,connected to RJ45 directly

Without RS-485 Pull-up and Pull-Down Resistor
