See some of the various system layout options available. You can click on the buttons for more information on those items. These are but a small sample of the possible system configurations. Please contact us to let us guide you through the clock selection process.

TimeCast Wireless System

TimeCast Analog TimeCast Digital TimeCast Base Station

TimeCast wireless system can combine battery or wired clocks. Power wires of an existing system can be reused to save on battery replacement costs.  The appropriate TimeCast clock can be powered by 120V or a simple 24V power supply.


 

Wi-Fi  Wireless System

TimeCast Analog TimeCast Digital TimeWise Server Master Clocks

TimeCast clocks can function as stand-alone Wi-Fi clocks. For system monitoring, they can directly check-in to National’s free cloud portal using existing Wi-Fi infrastructure. If only local monitoring is desired, a TimeWise Supervision Server or any LAN capable National Master Clock can be used.


 

3-Wire Synchronous System

DLU Digital Spectrum SeriesMaster Clocks

A typical National 3-wire clock system. Retired EX Series and RDS Series clocks can be replaced with DLU digital or Spectrum clocks.


 

2-Wire Instant Reset System

DLX Digital Spectrum Series Master Clocks

National’s exclusive instant reset protocol can send power and data over the same pair of wires.  The clocks can reset as soon as power is restored, eliminating the long wait for a 12-hour reset of other systems.


 

Replacement/Retrofit Options

DLU Digital  Spectrum Series

National Spectrum and DLU Digital clocks can coexist on Conventional 3-wire systems of other manufacturers. Refer to the clock datasheets for supported formats.


 

3-Wire System Upgrade

DLX Digital Spectrum Series Master Clocks

Conventional 3-wire clock systems of many manufacturers can be upgraded gradually with a National master clock.  Two-wire instant-reset clocks can coexist on the same wires as older 3-wire clocks (National or other’s).  After a power outage, the new clocks can reset to the correct time immediately.  Older clocks will reset as usual at the next 12-hour reset period.
