Set the Netmask
A netmask defines the number of bits taken from the IP address that are assigned for
the host part.
Netmask: Number of Bits for Host Part (0=default) (0) _
The unit prompts for the number of host bits to be entered, then calculates the
netmask, which displays in standard decimal-dot notation when the saved
parameters display (for example, 255.255.255.0).
Table 5-1. Standard IP Network Netmasks Representing Host Bits
Network Class Host Bits Netmask
A 24 255.0.0.0
B 16 255.255.0.0
C 8 255.255.255.0
Change Telnet Configuration Password
Setting the Telnet configuration password prevents unauthorized access to the setup
menu through a Telnet connection to port 9999 or by web pages. The password must
have 4 characters.
Change telnet config password (N) ? _
An enhanced password setting (for Telnet access only) of 16 characters is available
under option 6 Security from the Change Setup menu.
Note: A password is not required to access the Setup Mode window through
a serial connection.
DHCP Name
If a DHCP server has automatically assigned the IP address and network settings,
discover the unit by using the DeviceInstaller network search feature.
There are three methods for assigning DHCP names to the unit.
 Default DHCP Name: If the DHCP name is not changed and the IP is
0.0.0.0, then the DHCP name defaults to CXXXXXX (XXXXXX is the last 6
digits of the MAC address shown on the label on the bottom/side of the unit).
For example, if the MAC address is 00-20-4A-12-34-56, then the default
DHCP name is C123456.
 Custom DHCP Name: Create your own DHCP name. If using an IP address
of 0.0.0.0, the last option in Server configuration is Change DHCP device
name. This option allows you to change the DHCP name to an alphanumeric
name (LTX in the example).
Change DHCP device name (not set) ? (N) Y
Enter new DHCP device name : LTX
 Numeric DHCP Name: You can change the DHCP name by specifying the
last octet of the IP address. When you use this method, the DHCP name is
LTXYY where YY is what you chose for the last octet of the IP address. If the
IP address you specify is 0.0.0.12, the DHCP name is LTX12. This method
only works with 2-digit numbers (0-99).
