Synchronisation
TimeTools SR Series is a complete range of
Linux based Network Time Servers. The range
provides a real breakthrough in price and
performance. By utilising a customized Linux
kernel and an unmodified version of the latest
network time protocol distribution, NTP version
4.2, the SR series offers true Stratum 1
NTP/SNTP functionality.
Synchronize Multiple Platforms
The SR Series provides an accurate time
reference for synchronising multiple platforms,
including: Windows, Linux, CCTV, DVR’s, wall
clocks and network infrastructure.
5-Year Warranty and Free Lifetime Support
The SR Series NTP Server is a low-power
convection cooled device with no moving parts,
aiding long-term reliability. Our confidence in
the reliability of the device is reflected in the
provision of an industry leading 5-year warranty.
High Quality Rack-Mountable Enclosure
Housed in a compact, yet rugged, 1U high,
rack-mountable aluminium enclosure, the SR
series takes up minimal valuable rack-space.

KEY BENEFITS
Synchronize Windows,
Linux, DVRs, Wall Clocks
and Network Infrastructure
Accurate, Traceable Source
of Time Inside Your Firewall
Accurately Synchronize
Time Critical Processes
Secure
The SR series provides a reliable, highly
accurate, traceable, source of time inside your
firewall. No need to compromise security by
opening ports in your firewall. A secure, easy to
use, password-protected browser interface
(HTTP / HTTPS*) is provided for system
configuration and management. FTP/SCP* can
be utilised to download NTP statistics and
upload firmware upgrades, provided by
TimeTools free of charge.
High Sensitivity, Single Satellite in View GPS
A cutting-edge high-sensitivity GPS receiver
that can often operate with an indoor located
GPS antenna is utilised by the SR series.
Additionally, the new receivers can operate
from a single satellite-in-view making operation
from a window often possible. These features
potentially provide a great saving on installation
costs when compared to traditional roofmounted GPS antennas. Of course, our GPS
antennas are completely weatherproof and can
be mounted outdoors.
Multiple Reference Clock Options
Multiple optional external reference clock
combinations can be provided with the SR
series; GPS, MSF radio, DCF-77 radio and dual
GPS / radio reference capabilities. The SR
series provides true flexibility.
High Stability TCXO Oscillator Options
High-stability, GPS/ LF disciplined, TCXO
backup oscillator options are available to
maintain accurate time for extended periods in
the event of primary reference clock signal loss.
SR7110 – Competitively Priced
The SR7110 is an entry-level Linux based true
NTP time server at a highly competitive price. It
can utilise GPS or LF radio time references to
provide stratum-1 NTP functionality, ideal for
synchronising digital wall clocks and smaller
networks.
SR9210 / SR9750 – Feature Rich, Value
The mid-range SR9210 and SR9750 models
are high specification NTP network time
references. They incorporate a high-throughput
Ethernet network interface, combined with the
ability to accept GPS, LF radio or dual GPS/LF
external time references. The SR9750 also
incorporates a high-stability GPS/LF disciplined
Temperature Controlled Crystal Oscillator
(TCXO) for extended holdover. The SR9210
and SR9750 are ideal time references where a
large number of network time clients are to be
synchronised accurately and reliably.
SR9860D – Dual LAN, High Accuracy
The top-of-range SR9860D incorporates dual
independent LAN capability for synchronising
multiple networks. It also provides enhanced
precision along with a GPS/LF disciplined
TCXO for extended holdover. Ideal for reliably
synchronising multiple large networks with a
high degree of accuracy.
