Outputs - NTP Server
This Master Clock is an NTP server. This means that it can generate NTP or SNTP time data. This time data
can then be sent over a wired computer network to any other networked machine that accepts NTP/SNTP
time data. Some examples of devices that can accept NTP data from this master clock are DVRs, Voice-over-
IP telephones, IP-operated cameras, and desktop computers.
When using this master clock as an NTP server, the Master Clock
MUST BE SET TO A STATIC IP
ADDRESS
. A master clock that has been set to DCHP will occasionally refresh its IP address, making it
impossible for other devices to consistently receive NTP time data. Refer to the sections of this manual
labeled “Basing Configuration - DHCP and Static IP” and “Web Interface - IP Settings” for more
information.
IP devices may receive NTP/SNTP time from this master clock through the following procedure:
1) Locate the master clock IP address. There are three methods for doing this:
a) On the Web Interface, look under the IP Status tab for the field “IP” address.
b) For NTP 8000 master clocks, press and release the 1 and 9 buttons on the keypad simultaneously to
display the IP address.
2) Enter the master clock IP address as the NTP source for the NTP compatible device. Consult the IP
device’s manual for information on where to enter the IP address.
3) Confirm that the IP device is receiving NTP data from the master clock by comparing the time on the
master clock LED display to the time on the device. Consult the IP device’s manual for information on how
to view the time on the device.
