Central Clock System

Central Clock System

A master clock system is a set of synchronized clocks designed to always show exactly the same time by communicating with each other. Clock networks usually consist of a central master clock kept in sync with an official time source, and one or more slave clocks which receive and display the time from the master.

A Guide to Master-Slave Time Clock Systems

A master clock system is an electronic device that provides time synchronization signals to a number of slave clocks on a network. Typically, the master time clock maintains accurate time from a hardware clock source, such as GPS, GLONASS, Galileo or other sources of precise time.

A slave clock is a hardware device that typically depends on a master clock to for accurate time. A number of slave clocks synchronize with a master clock to provide a display of accurate time.
Slave clocks come in many shapes and sizes. They can connect to the master clock through either a cable or a short-range wireless signal. Slave clocks typically communicate on a clock network. The clock network can either be a simple wired serial network, a wired pulse signal or a more complex Ethernet network.
