The 6890 time servers are fully special network time server systems for NTP (Network Time Protocol). They support Global Navigation Satellite Systems (GNSS) GPS, Galileo, GLONASS and BeiDou for accurate and reliable time synchronization at very competitive prices. The 6890 series network time server systems have a compact design with a small enclosure for DIN rail installation. With an integrated 72-channel GNSS receiver for GPS, Galileo, GLONASS and BeiDou, reliable satellite time signal evaluation ensures the quality of received frequencies even in challenging and noisy installation conditions. This small and very high-quality time server is one of the most competitive time servers in the world with POE and 24V DC power supply and extensive protocols and internal firewall. 

The GPS6000-PRO Time Receiver accurately synchronises your time server with international atomic standards. The GPS6000-PRO provides highly accurate time data. With 32 satellite parallel tracking and class-leading high performance design, the GNSS decoder supplies time data accurate to within 30 nsec of UTC. The user programmable cable delay compensation ensures timing accuracy is maintained, even over long cable runs.

KEY BENEFITS 

• High accuracy timing for your time server 
• Reliable performance, even in weak signal and hostile RF environments 
• 30 nsec timing accuracy 
• Multi-constellation support (GPS/GLONASS/Galileo ready) 
• Simple installation into your data centre using existing cat 5 structured cabling

The MC2000 addresses the challenges of time synchronisation across multiple or large networks. With two fully independent network ports, flexible synchronisation options and reliable performance, the MC2000 is the solution for secure enterprise grade timing on large networks. The MC2000 provides high accuracy timing across two independent networks. With its triple processor architecture and high performance design, the MC2000 dual LAN NTP server enables the accurate synchronisation of devices across multiple networks. The high stability TCXO ensures timing accuracy is maintained, even during periods of antenna synchronisation loss.

Equipped with Ethernet/RS485/RF communication capabilities, the master and slave clocks can communicate effectively to ensure synchronization. In addition, the system features a built-in RTC to provide a backup timekeeping function in case the NTP server/GPS data is not available.The user-friendly browser-based configuration utility allows for easy setup and customization of time formats, timezone settings, and daylight saving time adjustments. Front panel LED indications provide visual feedback on the status of the system.

Time server 6842 is one of the most widely used time servers of the German Hopf brand. This time server has been installed in many projects. Time Server 6842 is installed in a modular way and has many expansion boards. Among these board is the antenna card. The antenna card has GPS and DCF77 antenna inputs. This board is updated based on the development of satellite frequencies for time servers. Versions 4505, 4507 to 4511 are add-on cards for the antenna card, which are replaced with pins on the antenna card. Devices similar to 6842 that do not have good satellite reception or their connection to the satellite has a problem, by replacing this board, the satellite connection will be established accurately and the system will be overhauled. Many collections are thinking of upgrading the firmware software on these cards, which is not accepted by HOPF and has caused many failures in the systems.
