The EZTCP CSE-M53N is a micro-sized embedded serial to Ethernet module which is pin-compatible with CSE-M53.

This module provides conversion functions to remotely control and manage serial devices over Ethernet. The ezTCP CSE-M53N is the perfect solution for environments where industrial operating temperature range (-40C ~ +85C) is demanded and those who plan to move forward to next-generation Internet protocol, IPv6. This embedded serial to Ethernet comes preloaded with basic communication functions (TCP, UDP, etc.) and strong security functions(SSL, MAC/IP filtering, etc.), along with a packet fragmentation separator so that it can be used diverse applications. This serial to Ethernet has a high speed(up to 921,600bps) UART port which can be extended to RS232/RS422/RS485 in accordance with the users' environment.

The CSE-M53N is ideal for various environments such as RFID Systems, Remote Monitoring Systems, Extending distance between two devices through the LAN, etc.
