Description:
•
GPS NTP time server is very simple low cost solution for Ethernet / Intranet time synchronization.
•
Each computer or devices with Ethernet connectivity to GPS NTP3 Time Server, can adjust own
local time to worldwide atomic clock standard via the GPS Global positioning system. GPS time is
linked to USA NIST atomic cesium standard.
•
In time server is built in NTP Ver.3 protocol (Network Time Protocol). It is platform independent of any
kind operation system.
•
NTP3 Broadcasting supported
•
SNMP traps output for UTC LOST FIX monitoring.
•
Time Server has built in HTTP Web implementation, to visit actual status of GPS receiver, local time,
and server setup.
•
Delivery included External GPS Receiver with active antenna built in waterproof case. Connection to
server through standard TP twisted pair cable up to 100m.
•
Real Time Clock is implemented with Lithium backup battery CR2430 also. Built-in RTC safely
keeping the time/date when the GPS signal is lost.
•
Time server is without AC/DC adaptor 12V/300mA shipped.

Summary of Contents for Black Box GPS NTP3
- Page 1 GPS NTP time server is very simple low cost solution for Ethernet / Intranet time synchronization. • Each computer or devices with Ethernet connectivity to GPS NTP3 Time Server, can adjust own local time to worldwide atomic clock standard via the GPS Global positioning system. GPS time is linked to USA NIST atomic cesium standard.
- Page 2 GPS DIN Wiring:...
- Page 3 Mounted LEDs: • Green LED near the ethernet RJ45 connector indicates ethernet connection. • RED LED if flashing, inform about UTC FIX Error. Server is not synchronized to GPS system. • Blue LED must flashing in 1sec interval, it is copy of the PPS pulse signal from external receiver Recommendation to power source: It is possible to use non stabilized DC power source, in range 9..24V.
- Page 4 Installation steps: • Short the jumper on PCB. It will cause default Ethernet Setup to below table values: IP address: 192.168.0.16 Subnet Mask: 255.255.255.0 Default Gateway: Not implemented = 0.0.0.0 Authentication name: Password: 123456 • Connect Time Server to DC power source, with standard AC/DC adapter. Required is 9..24V DC voltage with max current consumption 300mA.
- Page 5 Note: - be sure that your current proxy setup is correct or disabled, - inspect your firewall setup also. First time we strongly suggested to setup new password with link to Password Setup: Before new password window setup, old password will be requested; in the default setup is 123456.
- Page 6 From main window Click to link Network Setup: on setup window user can check actual network values, and change any value. • Broadcasting Interval: Time period in seconds, when Server sends the NTP3 broadcast message to broadcast IP address. • SNMP Trap IP: IP address of computer to which will be sending SNMP traps.
- Page 7 System status window Click to System Status link from main window: Anytime it is possible refresh this web page to obtain new values pressing Browser RELOAD button. NTP protocol: Time server has built in NTP Ver 3 protocol. All platforms such as UNIX, WINDOWS NT,XP,2000 supports NTP protocol.
- Page 8 SNMP TRAP description GPS Time server produce SNMP trap message on every UTC FIX lost. Status Byte: Description 1 = PPS pulse from GPS receiver missing , GPS receiver is not connected 0 = GPS data message present 1 = GPS Data missing , Fatal error, GPS receiver is not connected or Zodiac Data Message cable error Max period of SNMP trap is 1sec in according to every 1second GPS sends Data message about UTC FIX status and number of satellites measurements.
