Page 22: Notify Ip Change
3.6.1 DDNS (Dynamic Domain Name System) If the CSE-H25 obtains its IP address, it notices to the service provider. Then the service provider serves DNS service. So, even though user doesn‟t know the CSE-H25‟s IP address, user can connect to the CSE-H25 by the host name (after DNS looking up.) The DDNS service provider that the CSE-H25 supports is only Dyndns (http://www.dyndns.com) -

Page 29: Communication Mode
5 Communication Mode 5.1 Introduction Normal communication mode is suitable for the purpose of using CSE-H25. Normal communication mode can be classified into four modes – T2S, ATC, COD, and U2S – each of which is described in the following table. -
Page 30: T2S - Tcp Server
[Event Byte] settings. If the [Event Byte] is 0, the data that comes to serial port of CSE-H25 will not be recognized. If it is not 0, the serial data before TCP connection will be temporarily saved to be sent to the host after the connection. -
Page 31: Disconnection
CSE-H25 User’s Manual Ver. 1.2 designated [Data Frame], CSE-H25 will send the saved data. If the [Data Frame] is 0, CSE- H25 will send serial port‟s data immediately. The unit used for the [Data Frame] is 10m seconds, so CSE-H25 rounds down rest of the values. -
Page 32: Cod - Tcp Client
Data before TCP connection will be handled based on the [Event Byte] settings. If the [Event Byte] is 0, the data that comes to CSE-H25‟s serial port will not be recognized. If it is not 0, the serial data before TCP connection will be temporarily saved to be sent to the host after the connection. -
Page 33: Dns
[Timeout] is 1 second. 5.3.4 DNS If users set the host name instead of the IP address on the [Peer Address] box, CSE-H25 query the IP address of the host to its Domain Name Server (DNS). The IP address of DNS can be configured on ezManager. -
Page 34: Atc
CSE-H25 User’s Manual Ver. 1.2 In ATC mode, the user can control the CSE-H25 in a similar way to controlling the modem using AT command. In ATC mode, only a TCP connection is possible and both the server and the client can be configured. - Page 35 U2S is a mode that performs UDP communication. In UDP communication, data is sent in block units. Therefore, data that comes through CSE-H25‟s serial port must be classified in block units to send it elsewhere. The block unit classification process is performed as the following.
-
Page 36: Atc Mode
ATC Mode Overview CSE-H25 can be controlled by AT commands in ATC mode. For example, the peer host IP address can be set by AT+PRIP command and connect to the host by ATD command. Therefore, CSE-H25 communicates several hosts alternatively. -
