GPS, NTP or WiFi: which jumbo clock do I need?

The synchronization method decides where the clock can be installed and how accurate it stays.

A jumbo clock keeps time in one of four ways. The right one depends on what your location already has: a clear view of the sky, a network cable, or WiFi.

Several clocks in one building

Use a master clock with slave clocks, wired (RS485) or wireless. Tell us how many slaves and the cable length.

Power cuts

An internal UPS backup module is available so the clock keeps running during a power failure.

Long antenna cable

A 10 m GPS antenna extension cable is available for rooftop or external-wall mounting.
