Configuration Checklist
Our NTD200 clocks get their time signals from the Ethernet.
Therefore, before installing this device, one should be
prepared with the following basic configuration information
that the device will require. It may be necessary to obtain
some or all of this information from a network administrator
in your organization.
STATIC NETWORKING CONFIGURATION
__ IP address and netmask designation for device
__ Primary and secondary DNS (Domain Name Server)
__ Gateway/router
__ Primary and secondary NTP time references
DYNAMIC NETWORKING CONFIGURATION
__ Confirm that a DHCP/BOOTP service is accessible on the local
network
__ Determine if DHCP server will provide NTP server configuration
NTP ADDRESSING MODE
__ Determine if this device (client) will query the NTP server
(Unicast mode), listen for NTP broadcast messages (Broadcast
mode), or listen to NTP as part of a Multicast group.
NAMING
All NTP devices can be provided with a verbose name. The
name is arbitrary and may be useful for organizing and
managing devices once installed. By default, device names
are the product name abbreviation followed by the device’s
MAC address. Customers should designate their own custom
names relating to their own organizational requirements, 32
characters max.

internal check. Time from the RTC backup will be applied until
the NTD200 server signal is acquired.
