    C ‑ C ppendix loCk eQUenCe nTrodUCTion The GCS can be used to synchronize the real‑time clocks of various rail signal products. The procedure for doing so is referred to as the Clock Set Sequence. The sequence utilizes several different schemes that are categorized into three groups. The groups are identified by the hardware and messaging interfaces they employ.
  • Page 92 GCS U anUal – The GCS always attempts to set the time and date for each assigned Target Duration Device. Typically, 15 to 20 seconds are required to set the time and date for each Target Device. – The Terminal Ports implemented on all MICRO‑AIDE CWR, VDL Latency Compensation and PSM products are designed to support high speed, machine‑driven interfaces (e.g., a PC running GEA software).

    GCS U anUal • SNTP‑Unicast responses are only sent if the GPS Receiver is locked onto a valid GPS signal. This is done intentionally to avoid sending potentially inaccurate time and date data to perhaps hundreds of Target Devices connected to the LAN or WAN. It follows that when using Time Server Mode, the GPS antenna should be positioned to insure optimal signal reception.
