Normal Communication Mode 

5.1.

 

T2S(TCP To Serial) 

When a host connects to predefined local port, the EZL-200L accepts a TCP 
connection.  When the EZL-200L 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.  And the 
TCP/IP data coming from the remote host is TCP/IP-processed and transmitted to the 
serial port to establish data communication.   (Data coming to the serial port before TCP 
connection is established will be ignored.)   

To limit the peer host, user should set [Peer IP Address]. The only pre-defined host can be 

accessible. If [Permitted IP Address] is 0.0.0.0, any host can connect to EZL-200L.
