1 Overview

1.1 Overview

Almost all communication devices including PC are using serial transmission. In this type,

devices send and receive data in the order of each byte. The serial communication is quite

simple to implement but has weaknesses like short distance and hard maintenance.

To overcome those weaknesses, we offer “Serial Networking Solution” which allows the

serial devices to transmit/receive data over unlimited distance. CSE-H55N2 is one of “serial

networking” devices which lets the serial devices to connect to the Internet by converting

serial data to TCP/IP packet, and vice versa.

CSE-H55N2 is an upgrade version of CSE-H55N that has been designed to improve

stability against noise and electrical damage on RS422/485 line. There is no change in its

software

1.2 Features

IPv4 / IPv6 dual stack

Stateless / Stateful (DHCPv6) address auto-configuration

RS422/RS485 (Terminal Block)

Industrial temperature range (-40℃ ~ +85℃)

Variety of monitoring status (ezManager, TELNET)

Security Protocols SSL3.0/TLS1.0
