4. Host Mode Configuration

Host mode represents the operating session mode of the LS100. Several host modes are available for the data communication between the serial device and remote hosts. Since TCP is connection- oriented protocol, server, client, server/client modes are provided. Table 4-1 shows the brief description of the host modes. A factory default host mode is TCP Server.

Mode

Description

 

 

TCP server

Select this mode, when users want the LS100 to operate as a TCP server. The LS100 stands

 

by until there is any TCP connection request. If TCP connection is not already established at

 

that time, the LS100 accepts the request and the session is established. In the established

 

state, it transmits the data through the serial port if there is any data from the remote host.

 

Since the LS100 supports only one TCP session for the serial port, the additional TCP

 

connection request will be rejected if already established. This mode is useful when users

 

want to send data to the serial device at any time they want.

 

 

TCP client

Select this mode, when users want the LS100 to operate as a TCP client. When the serial

 

device sends data or pre-defined timer is expired, the LS100 tries to establish a TCP

 

connection to a remote server through its TCP port. If a TCP session is established between

 

them, the LS100 will send data to the server. If there’s any data from the server during the

 

session, it will also send the data through the serial port. However, if the LS100 failed to

 

connect to the remote server, the data from the serial port will be discarded. This is useful

 

when the serial device initiates sending data such as data gathering application.

 

 

TCP

If you are not sure which mode to choose, select this mode since it will be applied in most

server/client

applications. In this mode, the LS100 operates as TCP server AND client. If the connection is

 

not established, it will accept all incoming connection and connect to the remote host if there

 

are any data from the serial device. Otherwise, it will send data back and forth. In summary,

 

the LS100 will work as if it is virtually connected to the remote host.

 

 

For each host mode, required parameters for configuration is summarized in Table 4-2.
