PCS-9785 Satellite-Synchronized Clock
1-2
Date: 2019-07-05
IEEE 1588 protocol
This device supports the IEEE 1588 protocol (BC mode and OC mode) for clock
synchronization in SNTP or PRP network.
SNTP/NTP protocol
This device supports the SNTP/NTP protocol and can work as a network time server.
PRP/HSR
This device supports the Parallel Redundancy Protocol (PRP) and High-availability Seamless
Redundancy (HSR) protocol.
Recording
Automatically, this device stores all the self-diagnostic record, binary status change and
service log in its internal storage.
Output clock synchronization signal
The kinds of output clock synchronization signal is rich, including PPS (Pulse Per Second),
PPM (Pulse Per Minute), PPH (Pulse Per Hour), IRIG-B signal, timing message (serial),
SNTP/NTP timing message (network), IEEE 1588 signal, etc.
Output interface
Various kinds of output interfaces are provided, including RS-484, RS-232, TTL, dry contact,
AC modulation, optic fiber, RJ45, etc.
Dual power supplies redundancy
Dual power supply module is an option. The extra power supply module will be placed at the
other side of the device rack and works independently.
Double devices redundancy strategy
With a interconnection in using of IRIG-B signal, a set of two PCS-9785 can form the "dual
device dual network" redundancy strategy to provide a higher reliable and accuracy clock
synchronization system.
Output interface extension
The output interface extension is very flexible. In addition, the enormous interfaces are
isolated to each other.
Easy synchronization bus extension
It is simple to extend the time synchronization bus by adding a new PCS-9785 extension
device.
Human machine interface
The friendly HMI provides large scale LCD and navigation keypad for the display of real time,
satellite tracking status, IRIG-B inputting status, current clock source, etc.
