Netmask: Number of Bits for Host Part

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) _

Note:

Class A: 24 bits; Class B: 16 bits; Class C: 8 bits

The unit prompts for the number of host bits to be entered, then calculates the netmask,
which appears in standard decimal-dot notation (for example, 255.255.255.0) when the
saved parameters display.

WLAN Configuration (Option 4)

Without adequate protection, a wireless LAN is susceptible to access by unauthorized
users. For that reason, XPress DR+W features the WPA security standard, based on
IEEE802.11i. WEP is provided for backwards compatibility and interaction with older
devices.

Note:

Due to regulations, the country-specific setting has been removed from the setup

menu and Web Manager. We provide a separate utility for changing the Country/Zone
setting. The utility is called SetZone and is included in the XPress DR+W package. It is
also available for download from the Lantronix web site.

The syntax is SetZone []
