Description

Here's a lightly used, very good condition, fully working SyncServer S200 NTP server that obtains highly accurate and traceable time from the GPS satellite constellation. This unit has the upgraded OCXO oscillator installed for better free-running stability. The original GPS receiver system has been replaced with the latest generation of technology for assured service for years to come (see comments below for why this is important for anyone considering buying a SyncServer). Screenshots taken during my testing of the unit are provided below. The unit is in very good cosmetic condition and the VFD display is bright, clear and quick to light up. The photos show the actual item for sale. No antenna is included, but I would be happy to quote for including one if needed as I have the matching Symmetricom AT575 type listed separately. The antenna voltage is 12V so you cannot use one of the generic 5V antennas commonly offered for sale. And for best results the antenna needs to be mounted outside with a complete view of the sky. The unit has been reset to the factory logon defaults (logon with admin:symmetricom) ready for your install. The installed firmware is v1.36 which takes into account the April 2019 GPS epoch roll-over and prior leap second adjustments. The listing comprises the items you see in the images (only). No printed manual is included but a copy may be downloaded from https://www.prostudioconnection.net/0912/SyncServer_S200_S250_S250i_UserGuide.pdf if required. No other cables, documents or accessories are included.

Why Replace the GPS Receiver Module?

This unit has been upgraded with a new, latest generation GPS receiver module from iLotus. Why is that relevant (and maybe worth paying a little more for)? Pretty much all GPS clocks are by design going to fail at a future date. The problem is that the GPS system does not send out a date, but a week number. And in the GPS system there was only capacity in the original design to have a calendar of 1024 weeks (ie. a bit less than 20 years). At the end of the 1024 week period, the calendar goes back to the beginning again and many clocks start showing dates that are 1024 weeks in the past. The OEM Furuno GPS modules supplied in stock SyncServers are going to experience this "week number roll over" in September 2022 so I suggest that it's a reasonable approach to do a planned hardware upgrade now at very modest cost rather than just leave the problem out in the field and praying that someone else gets the "WTF just happened" call when the old card's firmware decides it's time to travel back in time to 2002.

The SyncServer S200 sets the standard which is shared by Symmetricom's other SyncServer network time servers.

Easy To Set Up and Maintain
SyncServers are the easiest to set up and maintain network time servers in the world. The front panel of the SyncServer S200 is designed to quickly bring the server online with a few front panel keystrokes or DHCP. To fully configure the unit, use the very intuitive web interface or the step-by-step wizards for the most common operations.

Highly Robust and Secure
The S200 provides reliable and secure network synchronization technology by combining multi-port, high-speed/ high-capacity network interfaces and versatile GPS timing receiver technology.

Flexibility and Performance
The multiple ports of the S200 provide the flexibility to adapt to different network topologies as networks grow and change. It supports a wide range of network protocols including IPv4 and IPv6, for easy management and seamless integration into your existing and future network. The high speed processor and a nanosecond clock assure high bandwidth NTP performance for hundreds of thousands of network clients.

Assured Perfect Timing
The Stratum 1 level S200 derives extremely accurate time directly from the atomic clocks aboard the GPS satellite system. Reliability is further enhanced via Stratum 2 operation by retrieving time from other user-designated time servers. All SyncServers can be upgraded to an internal Rubidium atomic oscillator to keep the time server accurate if the GPS signal is lost.
