CSE-M32 ezTCP Embedded 2-Port Serial Ethernet Module

  • $69.00

The ezTCP CSE-M32 is a 2 port embedded serial to Ethernet module that accomplishes conversion functions (serial to TCP/IP and vice versa) to provide your serial devices with seamless network connectivity. With the CSE-M32, you can remotely control and manage serial device over networks without changing existing software. This serial to Ethernet module is equipped with a TCP/IP stack optimized for compact size and multiple UART ports to enable high speed data transmission. Also, CSE-M32 supports DNS, DDNS, Telnet COM Port Control Option and two UART ports to be extended to RS232/RS422/RS485.

The CSE-M32 is especially suited for Secure Communication through the Internet, Bank Automation Systems, Extending distance between two devices through the LAN, etc.
