7. 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 "_".
