Disable Network
: uncheck
Host Name:
(Any name will suffice, but since this name appears on each line of the Time Delay’s
diagnostic logs, it is a good idea to keep this short.) The name should also be unique from other
devices on the network.
If
“Use DHCP”
if not checked, then enter a fixed IP address compatible with your local subnet.
For example,
IP Address:
192.168.1.20
Net Mask:
255.255.255.0
Default Router:
192.168.1.1
The
Name Servers
and
NTP Servers
fields provide the information needed to reach the public time
servers.
Note that NTP and the System Time in no way affects the accuracy of the Time Delay.
The
NTP Servers
field contains a list of time servers, either by numeric IP address, or by site name
(URL). Entries are separated by spaces.
The nonprofit Internet Systems Consortium, Inc. (ISC) maintains sites that automatically return lists of
public time servers to an NTP client such as the server. Hence, the
NTP Servers
field is initially filled
in with the URL’s for these sites (0.pool.ntp.org, for example). Of course, this list with the addresses
of specific time servers you may want to use can be overwritten. However, any attempt to clear the
NTP Servers
field will reset it to the default list.
Note:
When URLs (non-numeric site address such as pool.ntp.org) are used in the
NTP Servers
field, the IP address of at least one DNS (Domain Name server) in the
Name Servers
field must be
provided. Typically, this address is supplied by the Internet Service Provider.
These name servers translate URL names into numeric IP addresses needed to access the sites in
question.
When using a GPS-based time server which is connected directly to a local area network, enter its
numeric IP address (such as 192.168.1.60) into the
NTP Servers
field, leaving the
Name Servers
field
blank.
Also, if the numeric IP addresses of the public or corporate time servers on the Internet is known,
these addresses can be entered, separated by spaces, in the
NTP Servers
field, leaving the
Name
Servers
field blank, since there would be no URLs to be resolved.
Note:
Not all time servers allow unlimited public access. Refer to www.ntp.org for more
information.
