3: Wireless LAN Configuration 3.1 Overview IEEE 802.11, a Wireless LAN standard, requires one or more nodes and a wireless LAN access point (hereinafter referred to AP) as basic network elements. Normally, the word “node” refers to the notebook computers, personal computers, and PDAs that have Wireless LAN cards, although “node” refers to LS100W devices in this manual. 3.1.1 Infrastructure Mode and Ad-hoc Mode An AP is used to connect the LS100W to the Ethernet.
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 recognized that the wired Ethernet supported a very high level of internal security.
z Channel 11 (can check during booting sequence) WEP 64 or 128 bits PassKey ASCII or Hexadecimal WEP1 If the WEP function is to be used, a WEP key value must be set. The WEP1 key field is used to select between a 64 bit key or a 128 bit key. If WEP1 is set to ‘0’, the WEP function will be disabled. z WEP2 The WEB2 field selects whether ASCII code or Hexadecimal code will be used to represent the data values in WEP1. z Passkey The Passkey field is for user authentication.
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.
4.1 Static IP 4.1.1 Overview In the Static IP mode, users have to manually specify all the parameters such as IP addresses of the LS100W, 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 4-1. IP configuration parameters setting of Static IP mode 4.2 DHCP 4.2.1 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.
4.2.2 DHCP Configuration To make the LS100W work in DHCP mode, just set IP mode to DHCP as in Figure 4-2. > set ip dhcp OK > Figure 4-2.
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].
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.
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.
5.2.1 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].
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 periodically. Figure 4-3 shows the State Transition Diagram of the session operations in TCP client mode.
cyclic_connection_interval = cyclic connection interval in minutes inactivity_timeout = inactivity timeout in seconds. Destination IP address and destination TCP Port are the information on the remote host to which the LS100W will try to connect in TCP client mode. The IP address (or domain name) should be specified together with the TCP port number.
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.
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.
supported by the LS100W. 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 LS100W side. The DTR option can be set to one of three types: always high, always low or show TCP connection.
