Symmetricom PTP SyncServer S350 UPGRADED ublox GPS NTP Network Time Server 10MHz
( 364707449318) )
Tested/Guaranteed • PTP Grandmaster IEEE-1588 Option • Brand New ublox GPS Receiver Installed • TCXO Oscillator • Bright & Clear Display • GPS Discplined NTP Server • Latest Firmware • IPv6 Ready • Rack Ears Included
The photos show the actual item for sale
Note: This unit has been upgraded
with a new, latest generation GPS receiver module from
ublox. It is therefore unaffected by the September 18th
2022 week number rollover event that caused most
SyncServers to fail to sync to GPS and eventually to
show an incorrect date. The new card is good for
accurate GPS time and date reception until beyond 2037,
also achieves lock to GPS time much more quickly, with
the right antenna,
A lightly used NTP server that obtains highly accurate and traceable time from the GPS satellite constellation, in very good cosmetic condition and which has a bright and clear VFD display. The photos show the actual item for sale. This unit has the standard TCXO internal oscillator for free-running timekeeping should the GPS signal be lost temporarily. It also has the IEE-1588 PTP Master feature enabled. Rack ears are included as shown. It has been tested and confirmed to be fully working Firmware has been updated to v2.83.2 so it is compliant with the April 2019 GPS week number roll-over and previous leap second adjustments.
Note that an antenna is not included but I have matched 12V types listed separately and can edit the listing to include one if required. For best results the antenna needs to be mounted outside with a complete view of the sky. The unit's password has been reset to the factory defaults (logon admin:symmetricom) ready for your install. 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/1910/SyncServer-S300-S350_User_Guide.pdf. No other cables, documents or accessories are included. Screenshots taken during my testing of the actual item for sale are provided below for your peace of mind.

Unmatched High Performance with Unparalleled Flexibility and Security
The S300 has four dedicated and isolated Ethernet ports, one of which is Gigabit Ethernet - more than enough to meet the need of servicing thousands of NTP requests per second while maintaining microsecond caliber timestamp accuracy. Multiple ports 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. An optional upgrade to IEEE 1588 PTP grandmaster operations with hardware based, nanosecond accurate time stamping is available.
Enhanced Security - Secure and Easy Network Integration and Management
The S300 provides very reliable and secure network synchronization technology by combining multi-port network interfaces with multiple time reference technology and enhanced security protocols. TACACS+, RADIUS, SSL, Autokey, MD5, passwords, access control lists and more are standard for maximum security. All of the expected network management and monitoring protocols are standard in the S300.
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 S300 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.
Redundancy and Time Assurance
The internal modem is standard to connect directly to legal time provided by national time authorities. An optional AM radio is available to synchronize to national time broadcasts, which can be an alternative to GPS when GPS is not viable option.
Assured Perfect Timing
The Stratum 1 level S300 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.
Alarm Relays for Monitoring Systems
Aside from extensive software based alarms, the hardware based alarm of the S300 relays further enhance Alarming choices.
Customer Tested Time Server Design
The 5th generation Microsemi SyncServer S300 has decades of design experience behind it. Customer input is evident in every detail. From the front and rear panel design configurations to the state-of-the art web interface, the S300 is unsurpassed in reliability, accuracy, security and ease of use.
The SyncServer S300 is your answer to bringing perfect timing and therefore the highest performance to your network - securely, reliably and easily.
