The EZTCP CSE-M53G is a micro-sized embedded serial to Ethernet module that is pin-compatible with CSE-M53N.

The CSE-M53G module provides conversion functions to remotely control and manage serial devices over Ethernet. CSE-M53G is the perfect solution for environments where an industrial operating temperature range (-40℃ ~ +85℃) is required and for those who plan to move forward to the next generation Internet protocol, IPv6. 

This embedded serial to Ethernet module 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 in diverse applications. It has a high-speed (up to 921,600bps) UART port which can be extended to RS232/RS422/RS485, in accordance with the user's environment.

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

 Package includes:

1X CSE-M53G Embedded Serial to Ethernet Module

NOTE: This device is a module, requiring an interface board to provide the mounting and interface.  The EVB-M53G evaluation board, which can be purchased separately, has been developed for testing the CSE-M53G module before users design their own interface board. The evaluation board provides many interfaces including a DC jack, a serial port that is selectable for both RS232 and RS485, and an RJ45 for network connectivity.

Delivery is stock to 2 weeks, if the item is out of stock, please contact us for availability.
