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. 

 

 

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.

 

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. 

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