GPS Network Time Server After following the steps 1-4 the equipment has to lock on to the GPS sources and synchronise, this can take up to 30-minutes. When synchronisation is complete, the "locked" LED on the front panel, will turn green. A "power"... -
Page 13: Start-Up
GPS Network Time Server Start-Up Preliminary connections Before starting up the GPS Network Time Server, the following operations should be performed: • Place the system so that the lower and upper cooling air inlets are not obstructed. • Place the GPS antenna outdoor in a position such that it views the sky directly over 360 degrees (e. -
Page 14: Connection Quality
GPS Network Time Server • Connect the power supply circuit to the mains socket, or connect a DC power supply (24V for Series 2S or 48V for Series 2T) to the DC Power connector J2. CAUTION A break of the arrester conductor, inside or outside the unit, or disconnecting the earth terminal may turn the unit hazardous. - Page 15 Under such condition, the time message is no longer distributed (Time Of Day message, connector J3) and the clock no longer synchronizes with the GPS source. In such a case, contact the Black Box technical support. When all indicators are out, the clock is not powered.

Page 16: Operating Faults
110-9. Under such condition, the clock no longer synchronizes with the GPS source. In this case, contact the Black Box technical support. In continuous operation, the same faults cause the "POWER" indicator to go red. Setting out of service To set the GPS Network Time Server out of service, set the switch to position O and disconnect the "DC Power"... -
Page 17: Operation
GPS Network Time Server Operation Adjusting to UTC time This mode is used to acquire the time output from an external U.T.C. reference and to initialise the internal time of the system. The U.T.C. time reference is acquired fully automatically from the GPS receiver. This operating mode is accessed automatically at the end of successful self-testing. -
Page 18: Ntp Server Operation
GPS Network Time Server NTP server operation The GPS Network Time Server is a level 1 time server, according to the definition of time broadcasting and synchronization given in the NTP recommendation. It operates in conformance with the NTP version 3 described in recommendation RFC 1305. It delivers time information over the network in the server mode, only in response to client polling. -
Page 19: Maintenance
GPS Network Time Server Maintenance The GPS Network Time Server operates automatically. It requires no maintenance over a 10- year period. Apart from replacing, where necessary, one of the installation units, following damage or fault, the only curative maintenance operation consists of replacing the 2 fuses of the AC power supply. -
Page 20: Performance Characteristics
GPS Network Time Server Performance Characteristics Environment The GPS Network Time Server meets the safety recommendations for industrial equipment • Operating temperature: - 40 °C to + 85 °C ; • Relative humidity: 90%, no condensation, at + 40 °C ; •... - Page 21 GPS Network Time Server The overall synchronization performance including the client is highly dependent on parameters external to the GPS Network Time Server. Such influence is inherent to the operation of exchanges on UDP protocol for NTP. This performance depends on the message path over the interconnecting network(s), the load on the routing networks, the setup and the operating system used by the client.
