Figure 4-5. Network Clock Settings.
8. Select to Use DHCP (Dynamic Host Configuration Protocol) which is a protocol
used by networked devices (clients) to obtain the parameters necessary for
operation in an Internet Protocol network. This is the default.
Or
Select Use Fixed IP Address when desiring to use a static IP address, and
enter the following:
 Fixed IP address for the Web Clock. Obtained from network administrator.
 Subnet Mask for the Web Clock. Obtained from network administrator. In
computer networks based on the Internet Protocol Suite, a subnetwork, or
subnet, is a portion of the network's computers and network devices that
have a common, designated IP address routing prefix.
 Default Gateway for the Web Clock. May have to obtain from network
administrator. A default gateway is a node (a router) on a computer
network that serves as an access point to another network.
9. Select Service Port (default = 7) for the Auto-Sync Time Clock’s built-in TCP
service that allows a user to initiate an operation from an external application
(i.e., the Auto-Sync Utility functions). Any unreserved port 1 thru 65535 can be
used.
10.Select Enable Zero Configuration (default) for Zero Configuration to obtain
the parameters necessary for operation in an Internet Protocol network at a
local level. This is where you would turn Zero Configuration off if you did not
want the clock to broadcast its location. The most direct way to get to the clock
when this function is disabled is to know the IP address.
11.When finished entering the network settings, click on the button to save
network settings for the clock.
