Embedded Serial-to-Ethernet Module, RS232 US$20.00

Embedded Serial-to-Ethernet Module, RS232

The WE-200M is a small Serial-to-Ethernet embedded module which adds network and webserver function to legacy RS-232/422/485 devices. The WE-200M provides a transparent data channel between a serial device and the TCP/IP network, so that the serial device can be accessed by using standard TCP/IP protocols. The WE-200M can behave as a TCP server, a TCP client or an UDP node on a Ethernet network to fulfill versatile application requirements.

Note: This product does not have RJ45 and RS232 connectors. It is intended to be used as a daughtercard for your own designed base board or with the SE-100M Eval Board.

Alternatively the Aport-211W provides a WE-200M with a base board including Ethernet connector and magnetics in a metal enclosure.
