GPS Time Server (SYNTIME) is capable for the time synchronization requirements in various industries like power, process, IT, telecommunications, etc. It generates wide range of time code and pulse signals via different output ports like 1PPS, IRIG-B TTL/AM, NTP, Serial (RS232/RS485), PTP, Fiber ports.
GPS Time Server (SYNTIME) has redundant and non-redundant options for power supply and GPS receiver functionality. SYNTIME has a 16 x 2 LCD display for viewing of time parameters, status of GPS receiver parameters, discrete LEDs provide at-a-glance status and health information. The GPS receiver has a built-in RT with battery backup to maintain accurate time during power loss and instant recovery upon power restoration.
ENQUIRE
Network Time Protocol (NTP)
GPS Time Server (SYNTIME) is a Stratum 1 GPS-based full featured NTP Server for synchronizing all types of NTP and SNTP clients in LAN. NTP v2/v3 and v4 with all modes (Unicast/Broadcast/Multicast) and NTP related all necessary MD5 authentication mechanisms are provided in this device.
Networking Protocols
SYNTIME supports a full suite of networking protocols for its own administration and configuration management. These are IPv4, TCP, HTTP, SNMP, SSH, SCP, SYSLOG.
Security Features
