SC Series NTP Server Overview

TimeTools new SC 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, aluminium desktop enclosure the SC series takes up minimal valuable space.

By utilising a customized Linux kernel and an unmodified version of the latest network time protocol distribution, NTP version 4.2, the SR/SC series offers true NTP/SNTP functionality.

“The SC 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 SC series; GPS, MSF radio, DCF-77 radio and dual GPS / radio reference capabilities. They provide true flexibility along with high stability and performance.

The SC 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.

T-3072 GPS and MXS-01 Radio Antennas

Of course, our GPS antennas are completely weatherproof and can be roof-mounted outdoors, if required.

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

Customer Testimonials

Product: SC Series NTP Server
How would you rate your opinion of our company? Very High
How would you rate your opinion of our products? Very High
How willing are you to recommend our products to others? Very Willing
Feedback: “NHR was looking for a dedicated time sever as the Charity does not have direct internet access at the studio. We needed to have our PCs on the LAN synchronised to the correct time to enable the 24-hour broadcasting service (using PSquared’s Myriad suite) to run to time.
TimeTools provided excellent pre-sales advice, making suggestions based on our needs, rather than what they wanted to sell us. The SC Series NTP server is a very high quality product which has so far proved 100% reliable. TimeTools continues to provided occasional after-sales support when required which is the measure of a good company.
We would not hesitate to recommend Time Tools to anyone in the public, private or voluntary sector and we were delighted to buy British!”

SC7105 – LF\GPS Referenced
The SC7105 is an entry-level Linux-based true NTP time server at a highly competitive price. They can utilise GPS or LF radio time references to provide stratum 1 NTP functionality, ideal for synchronising digital wall clocks and smaller networks.

SC9205 – LF\GPS Dual Referenced
The mid-range SC9205 model 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 radio external time references. The SC9205 are ideal time reference where a large number of network time clients are to be synchronised accurately and reliably.

SC9705 – LF\GPS Dual Referenced With TCXO

The top-of-range SC9705 has all of the advanced features of the SC9205 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.
