Glossary
This section explains the glossary of terms used in this manual that are required to configure the
network.
Wireless Channel
If there is more than one Wireless LAN network with different ESS-ID on the same floor, and
they are communicating with each other, the baud rate may be slowed, due to the same radio
frequency being used. If this happens, you can still communicate regardless of other LAN
networks by using to use different frequencies (wireless channels).
Note: If they are communications using the wireless LAN, be sure to set all the Units the
same wireless channel.
DHCP Server
When configuring the network TCP/IP, be sure to set the IP address in each personal computer
and other devices. When there is a DHCP server on the network, it can assign IP addresses
automatically to the personal computers and the Access Point on the network. For the Windows
NT server and dial-up router, or other DHCP server function, refer to the Windows 2000,
Windows NT, or dial-up router manual, or consult the manufacturer.
ESS-ID
This ID is used to prevent cross-communication during communication between the Access
Point and personal computers within the wireless LAN. The Wireless LAN personal computers
that have the same ESS-ID as the Access Point can communicate with the Access Point. The
ESS-ID is case sensitive. You can enter a maximum of 32 alphanumeric characters, and the
underline "_".
LAN (Local Area Network)
Read as one word. A LAN is a network in a comparatively small area, such as campus or within
a single building. The LAN baud rate varies from 10 Mbps to 100 Mbps.
MAC Address (Media Access Control Address)
The MAC address is a physical address specific to each network card. The MAC address is
configured from a total of six bytes as follows: A vendor code comprising the lead three bytes
and a 3-byte user code. The vendor code is managed and assigned by IEEE. The user code is
managed using a unique (unduplicated) number from the network card manufacturer. That is, the
MAC address is assigned as a physical address unique throughout the world. In an Ethernet
LAN, the MAC address is used as a base to create a frame for sending and receiving.
TCP/IP (Transmission Control Protocol/Internet Protocol)
TCP/IP is a protocol equivalent to the network and transport levels of the OSI reference model,
and it is defined using RFC. Consequently, different terminals can communicate with each other
using TCP/IP.
• Normally, TCP/IP includes the application protocols TELNET and FTP.
• TCP/IP is the standard Internet protocol.
