Introduction
The Krontek GPS SNTP Timeserver is a fully featured, high
performance Stratum 1 referenced timeserver which derives its
time from the GPS satellite system. Its accuracy is within a few
milliseconds of GPS time which is referenced to the Atomic Clocks
maintained by the American National Institute of Standards and
Technology (NIST). The KT2000 series Timeservers will provide time
according to the SNTP protocol with only three satellites in view.
Configuration of the Timeserver is simple and is conducted via the
network using an easy to understand telnet interface. Once
configured, and in absence of a change in network
circumstances, your Timeserver will be fit for years of service
without additional maintenance.
Installation
The most important requirement in installation of your GPS SNTP
Timeserver is ensuring that the antenna is exposed to as much
clear sky as possible.
To facilitate this, the Timeserver comes with a GPS antenna with 5
meters of cable, a second 5m antenna cable extension, and an
angled window bracket to mount the antenna. NB: Do not
connect or disconnect the antenna while power is applied as this
may damage the GPS receiver.
Choose a window with an unobstructed view of the sky. You may
need to experiment to find a suitable position. This can be done
by placing the antenna in various positions
to check the satellite count. The antenna is weather-sealed and
may be mounted outside the building if required.
Once a suitable position has been identified, the mounting
bracket can be attached to the window using the included
Velcro® tape. For windows exposed to high temperatures, the
use of a silicon adhesive is recommended. The antenna is
magnetic and should be attached to the surface of the bracket
that has the small hole in it.
Screw the antenna connector to the antenna socket on the
timeserver end plate. Ensure connector is tightened to finger-tight
only. Connect the server to the network, then apply power to the
device.
