ESS-ID
The ESS-ID is an identification code required for communication in a wireless
LAN.
The same ESS-ID must be set to the access point and the wireless LAN PC to
enable communication.
The ESS-ID is upper/lower case sensitive and can consist of up to
32 alphanumeric characters including the under bar (_). The factory default
ESS-ID for the WLI-PCM is "RoamLAN".
The factory default is effective when using the WLI-PCM in a network consisting of only wireless LAN PC’s, however, this may allow unauthorized access
by an external computer equipped with the same model LAN card. We recommend that you change the ESS-ID to your own personal ID.
DS channel
Select 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 the
same DS channel to enable access.

Connection to Network
After all required settings for the computer are completed, you can
try connecting to the network. This chapter describes how to
access the network, check signal and communication conditions,
and select the target computer on the network.
Connection to network
Follow the steps below to access the network.
There are two types of connection: direct connection between wireless LAN PC’s
and connection to a computer on a wired LAN via an access point (available separately). The setting procedures vary depending on the connection type. Select
the appropriate procedure for your operating environment.
Connection between wireless LAN PCs
The factory default ESS-ID (RoamLAN) can be used for connection between
wireless LAN PCs, however, we recommend that you change the ESS-ID to
ensure further security.
When adjacent companies build networks using the same (factory default, for
example) ESS-ID, their networks may be inadvertently connected and confidential information may leak. It is safer to configure the network using an
access point (MELCO INC.’s WLA-T1) with a unique identification code automatically assigned.
If you change the ESS-ID, be sure to change that of the destination
computer. Computers with different ESS-IDs cannot be connected. Contact the administrator for the ESS-ID.

WLI-PCM User’s Manual
Assign IP address
An IP address must be set for each computer and other devices on the TCP/IP
network. There are several rules to observe when assigning an IP address to a
computer on the network.
■Rule 1
The same address cannot be assigned to multiple devices on a single network.
The IP address of each device must be unique.

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 2
You 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 is
included in the IP address, and communication is impossible if the network number is different.

If the sub net mask is "255.255.255.0", devices are regarded to be on the same
network when the first 3 elements of the IP address are the same. The IP
address 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 intercommunication is impossible.
Continued on next page
WLI-PCM User’s Manual
115
IP 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 address
192.168.1.255: Not available for use as IP address (used as the broadcast
packet)
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 communicate
with "192.168.2.1".
■Rule 3
The 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 can
refer to. Be sure to consult your network administrator, if possible, before assigning IP addresses.

Appendix
This chapter contains definitions of special terms and the specifications of the WLI-PCM.
Terminology
Networking terms used in this manual are defined below.
■ESS-ID
An identification code to classify computers on the wireless LAN into groups.
Computers can directly communicate with each other on the wireless LAN if they
have the same ESS-ID (i.e. they are in the same group) and are using the same
DS channel. Note that communication is possible only in the same group with
the same ESS-ID assigned. The ESS-ID is upper/lower case sensitive and can
consist 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 is
used by which device.
■IRQ (Interrupt Request)
Requests from all peripheral devices connected to your computer are processed
by the CPU, however, the CPU cannot estimate when a request is sent from
which device. If the CPU monitors all devices continuously, the monitoring time
becomes longer than the processing time, reducing performance. Therefore,
each device requests an "interruption" via an IRQ number with an urgent task for
the CPU. The CPU recognizes which device is requesting the interruption by its
IRQ number and processes the task. After the task is processed, the CPU
resumes its normal process.
■LAN (Local Area Network)
A network constructed in a relatively small area such as a single building or campus. Generally based on a data rate of 10 ~100 Mbps.
118
WLI-PCM User’s Manual
■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 latter half is the user code. The vendor code is controlled and assigned by the
IEEE, while network card manufacturers assign a unique number for the user
code. Therefore, the MAC address assigned to your card is not used anywhere
else in the whole world. Frames transmitted using Ethernet are based on this
address.
■Microsoft network client
Client software for using server services, such as Windows98/95/NT4.0. The
protocol used is generally "NetBEUI".
■NetBEUI protocol
Network transport protocol for small- and medium-size LANs. NetBEUI is equivalent to the transport and network protocol of the OSI protocol model. Integrating
NetBEUI and NetBIOS ensures an effective communication system in a workgroup LAN. This protocol is supported by Windows98/95/NT4.0.
■Peer to Peer connection
Communication between computers of the same level, performed via LAN or
WAN. Different from the server-client system, all computers on the network can
allow other users to access and use their resources. In regard to wireless LANs
in particular, this connection refers to the direct communication between wireless
LAN 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 reference model. This protocol is defined by RFC. Therefore, different terminals can
communicate with each other using TCP/IP.
• Includes general application protocols such as TELNET and FTP.
• TCP/IP is the standard protocol for the Internet.

■Access point
Device 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 is
connected to the access point.
■Client
Computer that receives services. The client can use the information and services
provided by the server.
■Protocol
Procedures and rules for transmitting data between terminals on a network.
For example, when two computers are communicating with each other, several
requirements for communication must be determined, such as which one sends
what message first, how the other one receives the message and replies to it, the
data format, and measures for communication errors. These requirements
ensure correct data communication.
■Resources (system resource)
Generic term for the IRQ, I/O port address, etc. assigned to peripheral devices
connected to computers (mouse, keyboard, etc.), LAN board, and LAN card.
