Modern NTP time server based on GPS

Modern NTP time server based on GPS
Product Detailed
1. Stratum 1 time server 2.Rubidium clock built in 3.CE/FCC/RoHS 4.Compatible with different OS 5.Heartbeat check



l           Serves as stratum 1 time server, receive signal from GPS setallite, or GPS and GLONASS dual satellite(optional), or from external serial port. Can be set as slave time server to synchronize with host time server.

l           Adopts RFC1119/1305 Network Time Protocol to transfer time.

l           Supports RFC1769/2030 SNTP(Simple Network Time Protocol) 

l           Compatible with different Operating System, namely Windows 98/2000/NT/XP,Linux,Unix,FreeBSD etc.

l           Four 10M/100M adaptive ports, among which port 0 serves as management port and cascade port, and supports SSH/SNMP/HTTP/NTP etc, while port 1,2,3 are for time transmission only.

l           Response capabability: >1000times per second.

l           Keeps highly precise time information when external time source does not work because of highly stable crystal or Rubidium atomic clock built in.

l           User can conduct settings, for example IP setting, through keyboard and display, which brings convenient installation and debugging.

l           Supports SNMP, with serial port log-on available

l           Supports HTTPS, can be managed through logging on Web.

l           Supports IRIG input and output, and 1PPS input and output (optional)

l           Supports TOD/1PPS/10MHz output (optional)

l           Supports 220VAC dual power supply or 48VDC power supply(optiona)

l           Supports interlocking between two servers. Two servers can conduct heartbeat detection and serve as backup for each other, which increases the reliability of time transmission.

l           CE/FCC labeled, and RoHS compliant.
