  • Page 36: Communication Mode

    5 Communication Mode 5.1 Introduction Normal communication mode is suitable for the purpose of using CSW-H80. Normal communication mode can be classified into four modes – T2S, ATC, COD, and U2S – each of which is described in the following table.

  • Page 37: T2S

    5.2 T2S In T2S mode, the CSW-H80 functions as a server. When a host connects to predefined local port, the CSW-H80 accepts a TCP connection. When the ezTCP accepts TCP connection, then the TCP connection is established. After connection is established, TCP/IP processing is performed on the data coming to the serial port, which is then transmitted to the remote host.

    [Access Lock] function. 5.2.1 Serial Data Before the TCP Connection If the [Byte Count] is 0, all data from the CSW-H80‟s serial port before the TCP connection are ignored. If the [Byte Count] is over 0, CSW-H80 stores serial data to its memory and it transmits these data when CSW-H80 is connected.

  • Page 39: Cod

    <COD connection sequence – Byte Count: 3> 5.3.1 Serial Data Before the TCP Connection If the [Byte Count] is 0, all data from the CSW-H80‟s serial port before the TCP connection are ignored. If the [Byte Count] is over 0, CSW-H80 stores serial data to its memory and it transmits these data when CSW-H80 is connected.

  • Page 40: Dns

    After CSW-H80 gets the IP address from the DNS server, it tries to connect the IP address. When CSW-H80 is in DHCP or PPPoE mode and the [Obtain DNS server address automatically] is set, CSW-H80 use the DNS server that it gets DNS server IP address during the DHCP or PPPoE connection.

    CSW-H80 User’s Manual Ver. 1.2 5.5 U2S U2S mode allows for UDP communication. In UDP mode, data are transmitted in blocks, which requires dividing data coming to the serial port into blocks before transmitting data. A procedure for dividing data into blocks is as follows:...

  • Page 43: Atc Mode

    6 ATC Mode 6.1 Overview CSW-H80 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, CSW-H80 communicates several hosts alternatively.
