View of Front Panel  (NTS-3000 & NTS-4000)

 

 

 

All NTS-x000 front panels are similar organized. The 2x20 characters LCD display shows: GPS (SAT) status, local or UTC time stamp information, GPS antenna position and various of system parameters lincluding internal temperature etc. The device comes with 6-key keyboard for: quick IP device configuration, firmware rev. info, factory default restoring etc. The RS232 and 2x USB are preserved for firmware upgrade/downgrade and future functionality/service purposes. LAN2 connector contains 2 led: green - indicates cable connection, yellow - flashes while data is being transmitted. Each plugging/unplugging of Ethernet cable will be indicated on LCD display by reviewing TCP/IP configuration for specific LAN interface.

View of Back Panel (NTS-4000)

 

 

On the back panel there is a power connection 110/230V AC (50Hz), LAN1, 2xGPS antenna connectors (A/B)

 

 

  • RJ45 antenna A channel, Input support: GPS, DCF77, 1PPS; Output mode: NMEA emulation   
  • RJ45 antenna B channel, Input support: GPS, DCF77, 1PPS; Output mode: NMEA emulation   
  • BNC  IRIG-B  input    (50 Ohm TTL)  analogue signal  /NTS-4000, NTS-5000 only/
  • BNC  IRIG-B  output  (50 Ohm TTL)  analogue signal  /NTS-4000, NTS-5000 only/
  •  BNC  10MHz  output (50 Ohm TTL)  /NTS-5000 only/
  •  BNC  1PPS   input     (50 Ohm TTL) /All models/
  •  BNC  1PPS   output  (50 Ohm TTL) /NTS-4000, NTS-5000 only/
  •  LED  1&2 /all models/

             Leds are OFF. No time synchronization when both Red & Green LEDs are OFF

 

             Green colour LED:

                 ON     - external time pattern sync (3x NTP servers, IRIG-B, IBM Sysplex)

                 BLINK - 1PPS time sync (internal build-in oscillator or external 1PPS input) 

                              

                           NTS-3000

                                -  RTC  real time quartz clock

 

                           NTS-4000

                                - high precision OCXO oscillator

 

                           NTS-5000

                                - high precision OCXO oscillator #1 (before Rubidium is PLL/FLL locked)

                                - atomic RUBIDIUM super precision oscillator #2 (after Rubidium is locked)

 

                           NTS-7000 (not available)

                               - active Hydrogen Masser

 

                           NTS-9000

                               - cesium beam /atomic clock/

 

                           NTS-dialup (not available, dial-up option transferred to NTP-3000, 4000, 5000)

                               - can be assembled with RTC, TCXO or OCXO oscillator


             Red colour LED:

                 ON     - GPS NMEA  time sync

                 BLINK - 1PPS (GPS) time sync

 

  • D-SUB9 Timer input   1PPS, IRIG-B (digital), IBM Sysplex (IBM Mainframes) /NTS-4000, NTS-5000 only/
  • D-SUB9 Timer output 1PPS, IRIG-B (digital), IBM Sysplex (IBM Mainframes) /NTS-4000, NTS-5000 only/
  • LAN1 Ethernet 10/100 interface /all models/
  • PE grounding /all models/
  • Power 110-230V AC connector w/ power switch ON/OFF /all models/

 

Each antenna Channel (A/B) can operate as INPUT or OUTPUT (GPS NMEA mode). Antenna input mode can support simultaneously SAT + RF AM /e.g. GPS + DCF77*/ receivers. Antenna OUTPUT mode supports only GPS (NMEA) emulation and 1PPS support. Elproma offers additional hardware for NTP time servers. New generation time reference pattern can be simultaneously drown from GPS L1/L2, SBAS, EGNOS, WAAS, GLONASS, and tomorrow from GELILEO too.
