DH Settings Click to access the DH Settings page, you can set the mode for asg IP addresses in a LAN. DH automatically assigns IP addresses to the network devices. If you are using the DH server, you need to do the configurations on the PC connecting with the device. For details, see "Configuring the Network Connection". • IP Address: The default IP address of the device is 192.168.1.1. • Subnet Mask: The combination of the subnet mask and IP address enables the flexible sub netting. By default, the subnet mask is 255.255.255.0.

Clip Settings • DH Server: It is used to assign IP addresses dynamically. If the DH server is Enabled, it can automatically assign IP addresses for PCs. It is recommended to select Enabled for the DH server. • Start IP Address/End IP Address: It is used to define the IP address range that the host can use during the IP address assignment. For example, in the network segment 192.168.1.0/24, the default IP address of the device is 192.168.1.1. The host IP address can range from 192.168.1.2 to 192.168.1.254. The minimum range is a single IP address. • DH Lease Time: The DH server automatically assigns an IP address to each device connected to the network. When the leased time expires, the DH server checks whether the device is connected to the network. If the device is disconnected from the network, the server assigns the IP address to another device. Thus, the IP address is not wasted. Start IP Address must be smaller than Note • The or equal to the End IP Address. • If the DH Server is Enabled, the configurations of Start IP Address, End IP address, and DH Lease Time are valid; otherwise, you cannot configure them.
