Marine Embedded Intelligent Master Clock CJCZ-3M II Q2 is one type of master clock in the marine master salve clock system. Marine Master Slave Clock is specialized for the time service system in the vessels. The system is composed of one master clock and dozens of slave clocks, they are connected to each other through signal cable and power cable. It can show the local time, international coordination UTC time and Beijing time simultaneously. The functions of marine master slave clock is as below:
1.Show the unified standard time.
2.Provide time signal to other devices.
As the basis of the whole clock system, the master clock is able to receive signals from the GPS standard time,alibrate its own time accuracy, and distribute the accurate time signals to each clock and other equipment. Also it can do the point-to-point control of slave clocks by keyboard. Master clock receives the GPS standard time signal via standard RS422 interface.When the external time source works normally, the signal will be as the master clock time benchmark. But when the external time source fails, the master clock will use its own crystal up benchmark as time.
