L3000-ENC02「6-Port Ethernet Interface」General for enterprise compute

The L3000-ENCRB "Six-Port" NTP network time server provides accurate, reliable, and secure high-precision satellite time reference for network devices, terminals, and servers within the firewall. It can synchronize the time for tens of thousands of clients using the standard Network Time Protocol (NTP, including versions 1/2/3/4) and the Simple Network Time Protocol (SNTP).

NTP network time servers have been widely applied in various fields such as finance, transportation, securities, electricity, mobile communications, petroleum, industry, e-commerce, industrial automation, cloud computing, security, smart cities, the Internet of Things, energy, and national defense.

The L3000-ENCRB "six-network-port" adopts a redundant architecture design, with a separate CPU and FPGA circuit internally constructed to form a taming system. The taming system receives ephemeris data from various satellites within the GPS Beidou system and atomic clock frequency reference, and achieves local clock synchronization and high-precision timing functions through delay compensation, filtering, and PID algorithms. With professional digital hardware design and an efficient Linux operating system, it possesses various reliable clock signal output functions.

The product design supports the full version of the NTP protocol, symmetric MD5 security encryption protocol, and asymmetric RSA certificate encryption protocol, with a client time synchronization accuracy better than 2 milliseconds. It also supports serial port NMEA0183 output, 1PPS, signal output, local and remote logging, green terminal dry contact alarm, USB port upgrade, network data upload and download, and other functions. When combined with unified monitoring software, it enables real-time monitoring of server operating status, client deviation status, client synchronization status, and alarm functions.
