Masterclock NTDS Series User Manual – v2 – December 2012

2. Verify that a gateway/router/firewall has been configured
that allows the device to communicate outside of its local
network.
3. Verify that the IP address configured for the device is
correct. If you manually enter or DHCP assigns an IP address
that already exists on the network, this will create an IP
address conflict. The device will reset its address to one
within the link-local address space “169.254.xxx.xxx”. If you
see that the IP address starts with “169.254”, obtain a new
IP address for the device or resolve the duplication. Consult
your network administrator for a range of available IP
addresses to avoid IP address conflicts.
4. If using DHCP mode, consult your network administrator to
ensure that your DHCP server is configured to automatically
supply the NTP server address before selecting the
“Use
NTP server(s) address provided by DHCP server”
checkbox. If
the DHCP server cannot automatically supply the NTP server
address(s), then deselect this option and enter the NTP
server(s) address(s) manually.
5. Verify that the device is connected to the Ethernet LAN.
6. Verify that all network cables, hubs, etc. are in proper
working order. Be sure that Ethernet crossover “patch
cables” are not being used where inappropriate.
Clock is not displaying
the correct local time or date
Possible reasons and solutions:
1.
Clock did not properly negotiate the DST to standard time
(or vice-versa) transition
2.
Time Zone offset has been configured incorrectly. Provide
the correct Time Zone configuration.
2. DST has been configured incorrectly. This is configured
separately from the Time Zone configuration. Provide the
correct DST configuration by either manually entering the
DST rules or selecting the single button configuration under
WinDiscovery. If using the convenient single-button
configuration for [US/Canada] or [EU DST], be certain to use
the latest version of WinDiscovery and apply it for each
device. If using the [Current Windows Setting] button to
apply the DST rules, verify that the rules on the computer
are correct.
3. If using DHCP/BOOTP for network configuration, consult
with your network administrator to see if the optional Time
Zone option has been changed as this option as provided by
DHCP can override manual settings.
4. If you have used the Set Time/Date function, note that the
device assumes that you have entered UTC and will apply
your Time Zone and DST configuration relative to the
manually entered time.
