Set Gateway IP Address
The gateway address, or router, allows communication to other LAN segments. The
gateway address should be the IP address of the router connected to the same LAN
segment as the unit. The gateway address must be within the local network.
Netmask
A netmask defines the number of bits taken from the IP address for the host section.
The host section is the part of the IP address that is specific to the UDS.
Note:
Class A: 24 bits; Class B: 16 bits; Class C: 8 bits.
The unit prompts for the number of host bits to enter, then calculates the netmask,
which appears in standard decimal-dot notation when the saved parameters display
(for example, 255.255.255.0).

Change Telnet configuration password
Setting the Telnet configuration password prevents unauthorized access to Setup
Mode using a Telnet connection to port 9999 or using Web pages. The password is
limited to 4 characters. An enhanced password setting of 16 characters is available
under Security Settings for Telnet access only.
Note:
No password is required to access the Setup Mode using a serial
connection.
DHCP Naming
A DHCP name is a unique identifier used for managing multiple DHCP hosts on a
network. Your unit ships with a default DHCP name of Cxxxxxx, where xxxxxx is the
last six digits of the Mac address.
You can change the DHCP name (up to eight characters) when configuring the
server in Setup Mode. Change the DHCP name to LTXdd, where 0.0.0.dd is the IP
