23 3: IP Address Configuration A valid IP address of the L S 100 needs to be assigned before it starts to work in the user's network environment. A network system administrator may provide the user with this IP address setting information for the network . The IP address must be unique within the network . Otherwise, the LS100 will not have a [...]

24 3.1 St atic IP 3.1.1 Overview In the Static IP mode, users have to manually specify all the parameters such as IP addresses of the LS100, valid subnet mask and the default gateway IP address. IP address is a n identification number assigned to a com puter as a permanent address on the network . Computers use IP addresses to identify and talk to [...]

27 4. Host M ode Configuration Host mode represents the operating session mode of the L S 100 . 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 mod[...]

28 set host hostmode par1 par2 ... where, hostmode: tcps=TCP server / tcpc=TCP client / tcpsc=TCP server & client parameters: if hostmode = TCP server ( tcps ) , par1 = listening TCP port, par2 = inactivit y timeout (sec) if hostmode = TCP client ( tcpc ) , par1 = destination IP address, par2 = destination TCP port, par3 = cyclic connection int[...]

29 - Sync - Sen t If the LS100 sends a connection request to a remote host, the state is changed from [Closed] to [Sync - Sent]. This state is maintained until the remote host accepts the connection request. This state is valid only in TCP client mode. - Established It repr esents “an open connection” . If one of the hosts accepts a connection [...]

30 Serial data transfer When a session has been established , the LS100 reads the data from the seria l port buffer till internal serial buffer is full or inter - character time interval reaches the time specified as inter - character timeout value . Then, it transfers the data to the IP address of the remote host. If there ’ s no remote host con[...]

31 4.1.2 TCP Server Mode Configuration To configure the LS100 to work as a TCP server, use ‘ set ’ command as follows: set host tcps listening_TCP_port inactivity_timeout + <CR> where, listening_TCP_port: Listening TCP port Inactivity_timeout: Inactivity timeout in se conds. Listening TCP port is the TCP port number through which remote h[...]

32 4. 2 TCP Client Mode Operations 4.2.1 Overview The L S 100 works as a TCP client, and the default TCP state is [Closed] in this mode. The remote host will be either Ethernet - Serial communication devices acting as a TCP server or a socket program acting as a TCP server running on users ’ PC. 1) Typical State Transition [Closed] -- > [Sync [...]

33 after the connection is established. Eventually, users can monitor the serial device periodically by making the remote host send the serial command to the LS100 whenever it i s connected to the remote host. This option is useful when users need to gather the device information periodically even if the serial device does not send its data periodi[...]

34 dest_ip = destination IP address dest_port = destination TCP port cyclic_connection_interval = cyclic connection interval in minutes inactivity_timeout = inactivity timeout in seconds. Destination I P address and destination TCP Port are the information on the remote host to which the LS100 will try to connect in TCP client mode. The IP address [...]

35 2) O perations The only difference from TCP server mode is that the LS100 will try to connect and send serial data to the remote host even if the TCP session is not established. The difference from TCP client mode is that it will accept i ncoming connection request from remote host if the session is not established. The detailed operation princi[...]

Parameter definitions for TCP server and c lient mode configuration are the same with TCP server mode and TCP client mode par[...]

37 5 : Serial Port Configuration To attach the serial device to the LS100 serial port, its serial port operation should match exactly to that of the serial device. Serial port configuration parameters are summarized in Table 5 - 1. Table 5 - 1. Serial Port Configuration p arameters Parameter Values Baud rate 1200, 2400, 4800, 9600, 19200, 38400, 57[...]

38 supported by the LS100. Hardware flow control method controls data communication flow by sending signals back and forth between two conn ected devices. The purpose of the DTR/DSR pin is to emulate modem signal control or to control TCP connection state by using serial port signal. The DTR is a write - only output signal, whereas the DSR is a rea[...]
