Using a Master Clock Interface it is possible to synchronise several Drax or Darlex to the same time signal. The interface accepts data in either RS485, RS422 or RS232 form from a master clock, such as the Tecton Master Clock. This information is then passed to the multiplexer by RS232. Each interface can synchronise 2 units.
The interface requires 12 V DC and takes 5-10 seconds to automatically detect and lock on to the incoming data. The unit is now synchronised. After the initial synchronisation, the time is synchronised on the hour, every hour.
The Rugby clock, maintained in Rugby, England, operates from a timing source based on radioactive decay to provide very high accuracy timing. The time is broadcast and using a receiver, can be used as the basis of a master clock. A source such as this can be used for the ultimate accuracy in evidential recordings.
