The ezTCP CSE-H55N2 from Sollae Systems is an industrial RS422/RS485 to Ethernet converter designed to be more stable against noise and electrical damage. It supports IPv6 addressing architecture as well as IPv4 and comes equipped with a terminal block for RS422 and RS485 interfaces.

The basic concept of this converter is to quickly and easily adding networking capabilities to your serial equipment to help you remotely control and monitor your serial equipment from anywhere in the world. The CSE-H55N2 features industrial operating temperature range (-40℃ ~ +85℃), various communication functions such as DNS, DDNS, and strong security functions (SSL, MAC/IP filtering, etc).

As well as industrial environments, the CSE-H55N2 is ideal for serial RS-422 / RS-485 to Ethernet control of diverse applications such as Solar Energy Management Systems, Converting RS422/RS485 Systems to TCP/IP Networks, and Remote Controlling Pan Tilt Cameras, etc.
