WLI-PCM User’s Manual10ESS-IDThe ESS-ID is an identification code required for communication in a wirelessLAN.The same ESS-ID must be set to the access point and the wireless LAN PC toenable communication. The ESS-ID is upper/lower case sensitive and can consist of up to32 alphanumeric characters including the under bar (_). The factory defaultESS-ID for the WLI-PCM is "RoamLAN".The factory default is effective when using the WLI-PCM in a network consist-ing of only wireless LAN PC’s, however, this may allow unauthorized accessby an external computer equipped with the same model LAN card. We recom-mend that you change the ESS-ID to your own personal ID.DS channelSelect the DS channel from channels A, B, or C.Selecting a channel sets the frequency used to transfer data. The target access point and the wireless LAN PC must be set to thesame DS channel to enable access.

WLI-PCM User’s Manual 115An IP address must be set for each computer and other devices on the TCP/IPnetwork. There are several rules to observe when assigning an IP address to acomputer on the network.■Rule 1The same address cannot be assigned to multiple devices on a single network.The IP address of each device must be unique.<Example>Computer A: 192.168.1.1 (255.255.255.0)Computer B: 192.168.1.2 (255.255.255.0)Computer C: 192.168.1.3 (255.255.255.0)::Computer X: 192.168.1.254 (255.255.255.0) The code in the brackets is the sub net mask. If the IP address is set to"192.168.x.x", the sub net mask should be "255.255.255.0".■Rule 2You cannot assign the network start address (XXX.XXX.XXX.0) or end address(XXX.XXX.XXX.255) to a device on the network. The network number isincluded in the IP address, and communication is impossible if the network num-ber is different.<Example>If the sub net mask is "255.255.255.0", devices are regarded to be on the samenetwork when the first 3 elements of the IP address are the same. The IPaddress represents the network number when the 4th element of the address is"0".Network A: 192.168.1.0 (network 192.168.1)Network B: 192.168.2.0 (network 192.168.2)Network C: 192.168.15.0 (network 192.168.15)Network D: 192.168.133.0 (network 192.168.133)Network E: 192.168.202.0 (network 192.168.202)Networks A through E are recognized as different networks and intercommunica-tion is impossible.Assign IP addressContinued on next page
WLI-PCM User’s Manual116IP addresses in network A are as follows.192.168.1.0: Not available for use as IP address (used as the network number.)192.168.1.1 ~ 192.168.1.254: IP address192.168.1.255: Not available for use as IP address (used as the broadcastpacket)When the sub net mask of network A is "255.255.255.0", for example,"192.168.1.1" can communicate with "192.168.1.2", but cannot communicatewith "192.168.2.1".■Rule 3The following IP addresses are generally used for a LAN.192.168.0.0 ~ 192.168.255.255 (255.255.255.0)There are a large number of detailed books about TCP/IP available that you canrefer to. Be sure to consult your network administrator, if possible, before assign-ing IP addresses.Windows98/95When TCP/IP is installed, follow the steps below to check the MAC address.Check MAC address1Click the Start button and select Run....2Enter "WINIPCFG.EXE" and click the OK button.The "IP Configuration" dialog box appears.3Select "MELCO WLI-PCM Adapter".

WLI-PCM User’s Manual1189AppendixThis chapter contains definitions of special terms and the specifica-tions of the WLI-PCM.Networking terms used in this manual are defined below.■ESS-IDAn identification code to classify computers on the wireless LAN into groups.Computers can directly communicate with each other on the wireless LAN if theyhave the same ESS-ID (i.e. they are in the same group) and are using the sameDS channel. Note that communication is possible only in the same group withthe same ESS-ID assigned. The ESS-ID is upper/lower case sensitive and canconsist of up to 32 alphanumeric characters, including the under bar (_).■I/O port address (Input/Output)A port for communicating information between the CPU and peripheral devices.An I/O port address is assigned to each device in order to determine which port isused by which device.■IRQ (Interrupt Request)Requests from all peripheral devices connected to your computer are processedby the CPU, however, the CPU cannot estimate when a request is sent fromwhich device. If the CPU monitors all devices continuously, the monitoring timebecomes longer than the processing time, reducing performance. Therefore,each device requests an "interruption" via an IRQ number with an urgent task forthe CPU. The CPU recognizes which device is requesting the interruption by itsIRQ number and processes the task. After the task is processed, the CPUresumes its normal process.■LAN (Local Area Network)A network constructed in a relatively small area such as a single building or cam-pus. Generally based on a data rate of 10 ~100 Mbps.Terminology
WLI-PCM User’s Manual 119■MAC address (Media Access Control Address)Unique physical address assigned to a network card.The MAC address consists of 6 bytes; the first half is the vendor code and the lat-ter half is the user code. The vendor code is controlled and assigned by theIEEE, while network card manufacturers assign a unique number for the usercode. Therefore, the MAC address assigned to your card is not used anywhereelse in the whole world. Frames transmitted using Ethernet are based on thisaddress.■Microsoft network clientClient software for using server services, such as Windows98/95/NT4.0. Theprotocol used is generally "NetBEUI".■NetBEUI protocolNetwork transport protocol for small- and medium-size LANs. NetBEUI is equiv-alent to the transport and network protocol of the OSI protocol model. IntegratingNetBEUI and NetBIOS ensures an effective communication system in a work-group LAN. This protocol is supported by Windows98/95/NT4.0.■Peer to Peer connectionCommunication between computers of the same level, performed via LAN orWAN. Different from the server-client system, all computers on the network canallow other users to access and use their resources. In regard to wireless LANsin particular, this connection refers to the direct communication between wirelessLAN cards without using access points.■TCP/IP (Transmission Control Protocol / Internet Protocol)A protocol corresponding to the network level and transport level of the OSI refer-ence model. This protocol is defined by RFC. Therefore, different terminals cancommunicate with each other using TCP/IP.• Includes general application protocols such as TELNET and FTP.• TCP/IP is the standard protocol for the Internet.

WLI-PCM User’s Manual122■Access pointDevice required for a wireless LAN PC to access a computer on a wired LAN.The ESS-ID of the target access point is required when the wireless LAN PC isconnected to the access point.■ClientComputer that receives services. The client can use the information and servicesprovided by the server.■ProtocolProcedures and rules for transmitting data between terminals on a network.For example, when two computers are communicating with each other, severalrequirements for communication must be determined, such as which one sendswhat message first, how the other one receives the message and replies to it, thedata format, and measures for communication errors. These requirementsensure correct data communication.■Resources (system resource)Generic term for the IRQ, I/O port address, etc. assigned to peripheral devicesconnected to computers (mouse, keyboard, etc.), LAN board, and LAN card.
