Enable the enhanced password setting and create a strong 16-character password. For details,
see

We do not recommend that you only use the 4-character basic password as it does not
offer sufficient security. Using no passwod is very dangerous.

DHCP Naming
If a DHCP server has automatically assigned the IP address and network settings, you can
discover the unit by using the DeviceInstaller network search feature or Monitor Mode (see
.
Note:
When you enter Monitor Mode from the serial port with network connection enabled and
issue the
NC
(Network Communication) command, you see the unit’s IP configuration.
There are three methods for assigning DHCP names to the unit.
Default DHCP Name
: If you do not change the DHCP name, and you are using an IP of
0.0.0.0, then the DHCP name defaults to XX.XX.XX.XX (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
: You can create your own DHCP name. If you are using an IP address
of 0.0.0.0, then 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 our 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, then the
DHCP name is LTX12. This method only works with 2 digit numbers (01-99).
