  • Page 6: Overview

    The serial communication is quite simple to implement but has weaknesses like short distance and hard maintenance. CSE-H55 lets the serial devices connect to the Internet. To communicate on the Internet, devices should use TCP/IP protocol, so CSE-H55 processes the converting serial data to TCP/IP.

  • Page 15: Installation And Test

    Before testing CSE-H55, users should connect both serial and Ethernet port to a PC. To connect the RS232 port of your PC and CSE-H55 via serial, you need a RS232 to 422/485 converter. It will be no problem that the Ethernet connection includes network hubs.
  • Page 16 Windows, and this is comfortable to use because it doesn’t need installation. First, search your CSE-H55 via network. All the values of parameters are set the default values in the factory. To apply it to your system, proper values should be set via ezManager.

Because CSE-H55 doesn’t have a RS232 port, a RS232 to RS-422/485 converter is needed. Of course, H55 should be in operation as [Serial Configuration Mode] and set to RS-422 (RS-485 is not available on this configuration).

  • Page 26: Communication Modes

    In this mode, CSE-H55 functions as a TCP server. CSE-H55 listens to a TCP connection from remote host. Once a host tries to connect to CSE-H55, it responses that request. After the connection is established, CSE-H55 converts the raw data from the serial port to TCP/IP data and sends them to the network and vice versa.
