Features 1 Expansion of supported GNSS satellite system

QZSS and GLONASS are now supported in addition to conventional GPS to minimize system operation stopping risk caused by GPS satellite failure and signal jamming.

Features 2  Significant improvement in processing capacity

NTP packet processing capacity has been improved more than 5 times and power consumption has been reduced by about 25%. 1000BASE-T (3Speed) is adopted as LAN interface to apply to the recent broadband network environment.

Features 3  Pursuit of operability

NTP server construction can be completed in 15 minutes via Web browser. In addition to the existing simplified setting function and the time synchronization status display from the front panel, the CLI setting function is available.

Features 4 Various fault monitoring function

SNMP and syslog as failure monitoring function ensure stable operation. Unauthorized access is prevented by Web setting. Immediate time distribution after starting is also possible by holding time information up to 6 hours.
