Time servers (rack and din-rail) are delivered as two main components:

  • independent ntpserver case
  • external IP65 GPS receiver

Cable schematics

gps-cable
  • It is strongly recommended to use standard TP cable for ethernet networks. It is low cost and good solution.
  • Low impedance chip drivers are used on gps receiver board
  • Time server is mounted with 100 Ohm resistors on both lines: DATA, PPS, to minimize glitches and noise.
  • GPS DATA baudrate: 9600b/sec
  • Protocol: ZODIAC connexant
