Clock Protocol - A specific time and duration of a set of correction pulses sent from a master clock to synchronize
a clock system. Through the development of clock systems many different clock system manufacturers designed
their own clock protocols. For this reason clocks cannot generally move from one system to another unless
the system has the same clock protocol. The AllSync Plus clock is designed to recognize many different clock
protocols.
Cold Start - AllSync Plus operational state in which power is applied for the first time or after the clock has not
had power for a sufficient amount of time to drain it to the point it resets its internal processor.
LED - Light Emitting Diode - Indicator light on the back of the AllSync Plus clock.
Master Clock - In a clock system, a device that acts as the source of time. The master clock transmits the time to
any number of secondary (or slave) clocks.
Movement - The inner mechanism of an analog clock that moves the clock’s hands.
Secondary Clock - Also known as a slave clock, this is a clock that synchronizes its timekeeping to that of a
connected master clock.
Synchronization - The process of bringing two clocks or time sources into phase so their difference is zero. In
the case of a timekeeping system, time synchronization takes place between the master clock and all secondary
clocks.
