Network timing server is a high-tech equipment developed for computers and automation equipment. This product can obtain standard time signals from GPS satellites (Beidou satellite, CDMA, B code interface, PTP), and transmit these signals to the equipment (computer, protection device, fault recorder, pulse) in the automation system through various interfaces (NTP/SNTP, serial port, B code, PTP).
HR series network time service server is produced by ARM embedded system technology, controlled by high-speed chip, without hard disk and fan design, with high precision, good stability, strong function, no accumulated error, high cost performance, simple operation, automatic intelligent operation, no need for operation and maintenance, and suitable for unattended operation. This product can provide accurate standard time signal and time stamp service for computer network system, electric power automation system, water conservancy automation system, e-commerce system, online B2B system and database preservation and maintenance system, and has been successfully applied in government, finance, communication, transportation, radio and television, security, electric power, water conservancy, national defense, medical care, education, IT and other fields.
Second, the network time server product features:
High precision, serial port/pulse up to 30ns, NTP client better than 2ms, fast time synchronization.
◆ Dual CPU works at the same time, 32-bit CPU dual-core processor, and DSP/CPLD is used to complete real-time high-speed processing;
◆ Unlimited expandable independent physical isolation ports with 10/ 100M (each port has an independent MAC address), and each port can be flexibly configured and used in different subnets and physical isolation networks;
As a first-class time server, it can provide time service for tens of thousands of clients, servers and workstations at the same time.
◆ Support Windows 9x/NT/2000/XP/2003/Vista, LINUX, UNIX, SUNSOLARIS, IBM AIX, HP-UX and other operating systems and all network devices supporting NTP protocol.
A variety of configuration methods (TELNET/WEB), easy to manage and upgrade, supporting MD5 encryption and SNMP network management;
◆ The equipment supports NTP and NTP protocols, and provides IBIG-B code mutual standby signal interface, so that the computer network and its network equipment can automatically and accurately synchronize time without additional programming.
◆ Support power interruption, GPS lost contact signal alarm (please indicate when ordering).
Dedicated embedded system, no hard disk and fan design, shockproof design, stable and reliable system.
◆ The case is treated with anti-magnetic treatment, which has strong anti-interference ability.
GPS receiving antenna pays attention to lightning protection design, stability design and anti-interference design, which has high signal receiving reliability and is not limited by geographical conditions and environment.
◆ The equipment has a variety of serial information output and interaction modes to meet the needs of different users.
◆ The serial port signal output is programmable, with key setting and convenient operation.
◆ The device can display the number of stars currently received online through the digital tube, which directly reflects the synchronization status of the device.
Rack structure, 1U/2U, 19 inch standard chassis, easy to install.
