2.4.7 ‘reboot’Command With ‘reboot’command, the LS100W will be rebooted immediately. Changed parameter values will be applied when the LS100W is up again.
3: Wireless LAN Configuration 3.1 Overview IEEE 802.11, a Wireless LAN standard, is the basic network element used by this device. It requires one or more nodes and a wireless LAN access point (hereinafter referred to AP). Often, the word “node” refers to the notebook computers, personal computers, and PDA’s that use Wireless LAN cards or LS100W products, in this section we will assume the “node” as LS100W, and describe further. 3.1.
Even when a certain value or an asterisk (‘* ’) symbol is entered in a channel value entry using the ‘set’ command, the LS100W will ignore those values and automatically set the values as the AP channel values of the group in which it belongs. 3.1.4 Security 802.11b based applications are different from wired Ethernet applications in the way they support security functions. The 802.11 Committee recognizes that the wired Ethernet supports a very high level of internal security.
Table 3-1 Wireless Lan Setting Parameters Parameter Values SSID Default / (Max 16 32 characters) Type Infrastructure mode or Ad-hoc mode Channel CH .1 ~ CH.13 (can be checked during booting sequence) Encryption Type None(0), 64 or 128 bits Key Input Method ASCII or Hexadecimal SSID Factory default value of SSID is “Default”. User can change this value according to the SSID of his AP to be used.
- ch: set channel number when adhoc mode - WEP1: 0=none / 1=64bit / 2=128bit - WEP2: a=ASCII type pass,h=Hexdecimal type pass - WEP_Key: ASCII type = 5(64bit) or 13(128bit) character input, - Hexdecimal type = 10(64bit) or 26(128bit) number input Note : If the type is set as infrastructure, channel will be set to the same value of the connected AP internally regardless of the value set by the user.
4: IP Address Configuration A valid IP address of the LS100W 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 LS100W will not have a valid connection to the network. Users can choose the desired IP mode out of the two IP operating modes, i.e., Static IP and DHCP. The factory default IP mode is DHCP mode.
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 a proper IP address which is unique and valid for your network environment. A subnet represents all the network hosts at one geographic location, in one building, or on the same local area network.
4.2 DHCP 4.2.1 Overview Dynamic Host Configuration Protocol (DHCP) is a communications protocol that allows network administrators to manage and automate the assignment of IP addresses centrally in an organization's network. DHCP allows a network administrator to supervise and distribute IP addresses from a central point and automatically send a new IP address when a computer is plugged into a different place in the network. As described in the section 4.
4.3 IP Filtering The LS100W has an IP address based filtering feature to prevent unauthorized remote hosts from accessing LS100W . 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 LS100W - Hosts on the a specific subnet can access the LS100W - Any host can access the LS100W The user may allow a host or a group of hosts to access the LS100W.
5: Host Mode Configuration Host mode represents the operating session mode of the LS100W. 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 5-1 shows the brief description of the host modes. A factory default host mode is TCP Server. Table 5-1.
set host hostmode par1 par2 ...
Sync-Sent If the LS100W 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 LS100W 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 LS100W, all the incoming data from the serial port are discarded.
5.1.2 TCP Server Mode Configuration To configure the LS100W 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.
5.2 TCP Client Mode Operations 5.2.1 Overview The LS100W 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 LS100W 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.
5.2.2 TCP Client Mode Configuration To configure the LS100W 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.
Or [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 LS100W is always connected to the specified remote host.
5.3.2 TCP Server/Client Mode Configuration To configure the LS100W 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.
6: Serial Port Configuration To attach the serial device to the LS100W serial port, its serial port operation should match exactly to that of the serial device. Serial port configuration parameters are summarized in Table 6-1. Table 6-1.
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 LS100W side. The DTR option can be set to one of three types: always high, always low or show TCP connection. If the DTR behavior is set to show TCP connection, the state of the DTR pin will be maintained high if the TCP connection is established.
7: System Administration Users can configure administrator username, password and device name using set command as follows: set admin username password devicename username: login username password: login password devicename: device name Figure 7-1 shows administrative parameters configuration example: > set admin adminuser adminpassword LS100W_test1 OK > Figure 7-1 Administration parameters configuration 43
