    3.1.5. Authentication Protocol Some wireless network requires authentication protocol (IEEE802.1x). Because EZL- 300L doesn’t support any authentication protocol, EZL-300L is not adoptable to some wireless LAN network if the network uses authentication protocol. In this case, use another product of Sollae Systems.

  • Page 32: Normal Communication Mode

    T2S (TCP To Serial) In T2S mode, the EZL-300L functions as a server. When a host connects to predefined local port, the EZL-300L accepts a TCP connection. When the EZL-300L 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.
