The Schematic layout of the system is as give above .The Digital Clock system has one MASTER CLOCK  &  Multiple  SLAVE  CLOCKS. The data generated at the MASTER is transmitted  to the SLAVES, using the RS-485  SERIAL mode of communication.

The master clock uses Micro-controller based circuitry. Its Clock functions are generated from a quartz controlled RTC chip. The uniqueness of this chip is that it is backup on power failure  by a LITHIUM battery and the low power consumption of the circuit gives a long battery life. The time is displayed using four digits of RED LED displays,   two digits to the left .  for HRS.  and the two digits to the right for MINS. Two rugged Push-to-ON switches are used to set the clock .

The  data from the master clock is received through a 3 – core Cable using the Serial mode of communication & it is processed and displayed  using  Microprocessor-based circuitry. The time is displayed  using  RED LED displays.  The Slave Clock in addition to being synchronized with the MASTER has its own RTC chip with Battery backup , which continues to work independently providing normal Clock functions during a link failure with the master. All these inbuilt safety factors makes it a very reliable CLOCK system
