PRODUCT OVERVIEW

TimeTools SR Series provides a complete range of Linux based, true Stratum-1, NTP Network Time Servers that represent 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.

GPS, Radio and Dual Reference Clock Options
Multiple 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.

The SR series is also 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 weatherproof and can be roof-mounted outdoors.

High Stability Extended Holdover Option
High-stability GPS/LF disciplined Temperature Controlled Crystal Oscillator (TCXO) options are available to maintain accurate time for extended periods in the event of GPS / radio reference clock signal loss.

Secure Configuration and Maintenance
A secure (HTTPS), easy to use, password-protected user interface is provided for system configuration and management. FTP/SCP can be utilised to download NTP statistics and upload firmware upgrades, available from TimeTools free of charge.

5-Year Warranty
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.

SR7110 – Entry Level, Competitive Price
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 clocks, DVR’s and smaller networks.

SR9210 – Feature Rich, Value
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 GPS / LF radio 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 – High Stability, Extended Holdover
The SR9750 provides all the features of the SR9210 with the additional benefit of a high-stability disciplined TCXO oscillator for extended holdover in the event of primary reference loss. Ideal where a highly reliable source of time is required.

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.
