7 Synchronisation via Serial Interface

7 Synchronisation via Serial Interface

In addition to the synchronisation via the integrated DCF77 receiver it is possible to synchronize the ANZ14 V4
by a time sting from the serial port input. In this case the ANZ14 can be used as a display for a pre-connected
master clock. The incoming time string sets the ANZ14 time that is running free from this moment. The ANZ14
keeps synchronisation to the master clock if the time string comes periodically (once per second or once per
minute). This time string is spread concurrently by the serial port output to apply the time string to one or
more further displays.(Examples for cascading:)

The RS422 current loop interface allows to span distance up to 1200 meters between the systems. Using the
RS232 driver the distance between two systems is limited to 15 meters.
