Parameter value display help [group] + Shows command usage screen. - If group is omitted, shows help screen. - If group is specified, shows 'set' command usage of the group.
next indicates the default gateway IP address. If users want to change only one of the parameters of the group, users can omit trailing parameters and/or can use ‘*’ to keep a parameter value. The screen below will show how to change subnet mask only without changing IP address and gateway IP address. > set ip static * 255.255.0.0 OK > Figure 2-10 Changing only one parameter value example Command usage of ‘set’ will differ depending on the groups.
The group means the category where parameters belong to as like ‘set’ command. For example, if users want to view parameter values related to IP configuration, get command as Figure 2-12 can be used. > get ip IP_mode: static IP_address: 192.168.1.100 Subnet_mask: 255.255.255.0 Gateway: 192.168.1.1 > Figure 2-12 Getting ip configuration screen ‘status’ group is a special group where ‘set’ command does not apply. ‘get status’ will show current system status screen. > get status Serial_no.
2.4.3 ‘help’ Command With ‘help’ command, users can find command usage help in the console screen. Basic command usage is as follows: help [group] + where, if group is omitted, overall help screen will be displayed if group is specified, ‘set’ command usage of specified group will be displayed. Figure 2-15 shows help screen when no group is specified while Figure 2-16 shows help screen with ‘ip’ group specified. > help set group par1 [par2 ...
2.4.4 ‘factorydefault’ Command With ‘factorydefault’ command, users can load factory default parameter values in console. Command usage of ‘factorydefault’ is as follows: factorydefault [option] + where, - if option is omitted, all parameters are set with factory default values. - if option='-ip', all parameters except IP settings are set with factory default values. Loaded values are not saved until ‘save’ command invoked.
2.4.7 ‘reboot’ Command With ‘reboot’ command, the LS100 will be rebooted immediately. Changed parameter values will be applied when the LS100 is up again.
3: IP Address Configuration A valid IP address of the LS100 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 valid connection to the network. Users can choose the desired IP mode out of the three IP operating modes, i.e., Static IP, DHCP and PPPoE.
3.1 Static 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 an identification number assigned to a computer as a permanent address on the network. Computers use IP addresses to identify and talk to each other on the network. Choose the proper IP address which is unique and valid on the network environment.
> set ip static 192.168.1.10 255.255.255.0 192.168.1.1 OK Figure 3-1 Setting IP configuration parameters for Static IP mode 3.2 DHCP 3.2.1 Overview Dynamic Host Configuration Protocol (DHCP) is a communications protocol that lets network administrators manage and automate the assignment of IP addresses centrally in an organization's network.
3.2.2 DHCP Configuration To make the LS100 work in DHCP mode, just set IP mode to DHCP as in Figure 3-2. > set ip dhcp OK > Figure 3-2 Setting DHCP mode 3.3 PPPoE 3.3.1 Overview PPPoE (PPP over Ethernet) is a specification for connecting multiple computer users on an Ethernet local area network to a remote site through common customer premises equipment, which is the telephone company's term for a modem and similar devices.
3.4 IP Filtering The LS100 has an IP address based filtering feature to prevent unauthorized remote hosts from accessing LS100. The user can allow one of the following scenarios by changing the parameter settings: - Only one host of a specific IP address can access the LS100 - Hosts on the a specific subnet can access the LS100 - Any host can access the LS100 The user may allow a host or a group of hosts to access the LS100. Then the user must enter the IP address and subnet to be allowed for accessing.
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 connectionoriented 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.
set host hostmode par1 par2 ...
Sync-Sent 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 represents “an open connection”. If one of the hosts accepts a connection request from the other host, the connection is opened and state is changed into [Established].
2) Operations Serial data transfer When a session has been established, the LS100 reads the data from the serial port buffer till internal serial buffer is full or inter-character time interval reaches the time specified as intercharacter timeout value. Then, it transfers the data to the IP address of the remote host. If there’s no remote host connected to the LS100, all the incoming data from the serial port are discarded.
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 + where, listening_TCP_port: Listening TCP port Inactivity_timeout: Inactivity timeout in seconds. Listening TCP port is the TCP port number through which remote host can connect a TCP session, and, send and receive data. Incoming connection request to the ports other than Listening TCP Port will be rejected.
4.2 TCP Client Mode Operations 4.2.1 Overview The LS100 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-Sent] --> [Established] --> [Data] --> [Closed] At start-up, an initial TCP state is [Closed].
Cyclic Connection It Cyclic Connection function is enabled, the LS100 will make an attempt to connect to the userdefined remote host at certain interval even if there’s no incoming serial data from the device. If the remote host prepares certain data, it will be transferred to the serial device via its serial port after the connection is established.
4.2.2 TCP Client Mode Configuration To configure the LS100 to work as a TCP client, use set command as follows: set host tcpc dest_ip dest_port cyclic_connection_interval inactivity_timeout + where, dest_ip = destination IP address dest_port = destination TCP port cyclic_connection_interval = cyclic connection interval in minutes inactivity_timeout = inactivity timeout in seconds.
[Listen] --> [Sync-Sent] --> [Established] --> [Data] --> [Closed] --> [Listen] The initial state is [Listen]. If there are data coming from the serial port, it will connect to the remote host as a TCP client. If there is incoming connection request from the remote host, it will accept the connection as a TCP server, and then transfer data through the serial port. Thus, users can assume that the LS100 is always connected to the specified remote host.
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 where, listening_port = listening TCP port dest_ip = destination IP address dest_port = destination TCP port cyclic_connection_interval = cyclic connection interval in minutes inactivity_timeout = inactivity timeout in seconds.
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.
The factory default setting of the flow control is None. Only hardware flow control using RTS/CTS is supported by the LS100. Hardware flow control method controls data communication flow by sending signals back and forth between two connected 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 read-only input signal in the LS100 side.
