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.
