DHCP Operation and IP Address Display during Startup

DHCP Operation

DM-NC40 supports DHCP.

If there is DHCP server in same LAN, network settings, i.e. IP address, subnet mask, default gateway, are provided from the DHCP server to the unit after power on or rebooting.

After turning on the power or rebooting, the unit displays IP address. If there is DSCP server in same LAN, provided IP address from the DHCP server will be displayed on the front of the unit.

If there is no DHCP server, IP address “10 0 0 1” is displayed after about 2 minutes and the IP address and subnet mask are set to the default values of 10.0.0.1 and 255.0.0.0, respectively.

If the IP address could not be acquired:

After about 2 minutes

Initialization operation

When DHCP server is not available, network settings by manual may be required. Use Web browser (see page 30) or API commands described in page 54 to change the setting to “Manual”.

*Changing from DHCP to Manual is possible from Web browser, but you need to use API command to change from Manual to DHCP.

*During DHCP is enabled, IP Address, Subnet Mask, Default Gateway, Domain Name and DNS Server settings cannot be set from Web browser.
