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. The default setting is 0.

DHCP Name

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 10: Monitor Mode).

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.
