PRODUCT OVERVIEW

TimeTools new SR Series NTP servers are a range of Linux based true Stratum 1 NTP Network Time Servers that provide a real breakthrough in price and performance.

Housed in a rugged, yet compact, 1U high, rack-mountable enclosure, the SR series takes up minimal valuable rack-space.

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 NTP/SNTP functionality.

“The SR series provides a reliable, highly accurate, traceable, source of time inside your firewall”.

UPDATE !!! The SR/SC series is now provided with a cutting-edge high-sensitivity GPS receiver that can often operate with an indoor located GPS antenna. 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 roof-mounted GPS antennas. Of course, our GPS antennas are completely weather-proof and can still be roof-mounted, if required.

MULTIPLE REFERENCE CLOCK OPTIONS

Multiple optional external reference clock combinations can be provided with the SR and SC series; GPS, MSF radio, DCF-77 radio and dual GPS / radio reference capabilities. They provide true flexibility along with high stability and performance.

High-stability disciplined TCXO oscillator options are available to maintain accurate time for extended periods in the event of GPS / radio reference clock signal loss.

EASY TO CONFIGURE AND MAINTAIN

An easy to use password-protected web interface is provided for system configuration and management. FTP can be utilised to download NTP statistics and upload firmware upgrades, provided by TimeTools free of charge.

INDUSTRY LEADING 5-YEAR WARRANTY

The SR Series NTP Servers are low-power, convection cooled, devices with no moving parts, aiding long-term reliability. Our confidence in the reliability of the SR range of devices is reflected in the provision of an industry leading 5-year warranty.

MODELS

SR7110 - LF / GPS REFERENCED

The SR7110 is an entry-level Linux based true NTP time server at 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 - LF / GPS / DUAL REFERENCED

The mid-range SR9210 provides a high specification NTP network time reference. It incorporates a high-throughput Ethernet network interface, combined with the ability to accept GPS, LF radio or dual reference GPS / LF external time references. The SR9210 is an ideal time reference where a large number of network time clients are to be synchronised accurately and reliably.

SR9750 - LF / GPS / DUAL REFERENCED WITH TCXO

The top-of-range SR9750 has all of the advanced features of the SR9210 but also incorporates a high-stability GPS disciplined Temperature Controlled Crystal Oscillator (TCXO). The high precision TCXO backup reference clock provides extended holdover periods in the event of primary reference signal loss.
