The only difference from
TCP server
mode is that the LS100 will try to connect and send serial data to

detailed operation principles are the same as that of
TCP server
and
TCP client
mode.

4.3.2 TCP Server/Client Mode Configuration
To configure the LS100 to work as a TCP server/client mode, use ‘set’ command as follows:
set host tcpsc listening_port dest_ip dest_port cyclic_connection_interval inactivity_timeout
