Automatic Acquistion of IP Addresses from a DHCP Server
Appendix-15
CBM-20A/20Alite
Name Solution Using NetBIOS over TCP/IP
The CBM-20A allows names to be solved by using NetBIOS over TCP/IP (NBT). NBT can be
used when the PC and CBM-20A are in the same subnet, and the system name of the CBM-
20A is used as the NetBIOS name. For example, if the system name of the CBM-20A is the
initial value (unit serial number L20234301234), entering http://L20234301234/ as the
address in Internet Explorer will start the CBM-20A’s "group monitor" application.
The relationship between the NetBIOS name and IP address is cached in the PC for a
set time (about 10 minutes). Consequently, if the IP address of the CBM-20A is
changed, it may not be possible to solve it from the PC based on the NetBIOS name
until the cache is cleared.
When using Internet Explorer 7 or later as the browser, change the browser setting so
that the system name is included in the intranet.
"2.9 Precautions Related to Internet Explorer Operations" P. 2-32
The name solution using NBT is available both when the IP address setting is DHCP
mode and when it is Fixed IP address mode.
Character Types and Name Length
The character types and name length that can be used with the CBM-20A are indicated in the
table below.
Due to system name and PC restrictions, the permissible ranges for the character types and
length of the host name and NetBIOS name may be narrower than those stipulated with RFC.
