Before Installation - Clock Setup - Network Servers
Time Input – From an In-House NTP Time Server or from a Master Clock
If the facility has their own in-house NTP Time Server or a master clock capable of providing time data to
the IP clocks, the IP clocks should be programmed accordingly. To set the clocks to receive the time data
from the in-house time source, please follow the below steps:
• Set the in-house NTP Time Server or master clock (capable of providing time data to the IP clocks) with a
static IP address.
• Once the IP address of the in-house time source has been identified, program it in the clock “1st Server
Address” text box in the “Network Servers” tab of the clock built-in web interface.
• Make sure to click the circle next to the “1st Server Address” text box, which will command the clock to
take time data from this selected time source.
• Make sure that the option “Rotate Servers” is not selected, which commands the clock to receive time
data from the “1st Server Address” as long as it is active.
• Regardless of what server or master clock you are using as a time source, all IP clocks must still be set
with the UTC/GMT Offset and DST separately, as explained in this manual.
• If you only want the clocks to receive time data from the in-house NTP time server or from the in-house
master clock, you can delete all other pre-loaded server addresses (2nd Server Address – 10th Server
Address). If you leave these third-party time servers listed, they can be used as a backup to the in-house
NTP time server, as long as the clocks can access the internet.
