5.5.8.1 DHCP Function
DHCP (Dynamic Host Configuration Protocol) allows network administrators
centrally manage and automate the assignment of IP (Internet Protocol)
addresses on a computer network. When using the TCP/IP protocol (Internet
protocol), it is necessary for a computer to have a unique IP address in order to
communicate to other computer systems. Without DHCP, the IP address must
be entered manually at each computer system. DHCP lets a network
administrator supervise and distribute IP addresses from a central point. The
purpose of DHCP is to provide the automatic (dynamic) allocation of IP client
configurations for a specific time period (called a lease period) and to minimize
the work necessary to administer a large IP network. To manually configure the
IP address of the controller, move the cursor bar to DHCP Function item, then
press Enter key to show the DHCP setting. Select the “Disabled” or “Enabled”
option to enable or disable the DHCP function. If DHCP is disabled, it will be
necessary to manually enter a static IP address that does not conflict with other
devices on the network.

that the assigned IP address is in the same range as the default router address
and that it is unique to your private network. However, it is highly recommend
