Wired Clock System

Wired Technology :

---

A master clock drives and synchronises the slave clocks, and keeps precise and accurate time to all clocks.

The master clock is usually connected to a Radio or a GPS antenna.

In a wired network, slave clocks can be synchronised either by current impulses or by a digital signal coming from the master clock.

Time Distribution : Impulse

A signal is sent through polarised impulses every minute, half minute or second.
This technology is suitable for small installations where there is a limited number of slave clocks, and limited wiring distance.

Advantage :

- Cost effective solution for small clock systems with analogue clocks

Time Distribution : AFNOR / IRIG B 

The AFNOR / IRIG B (Time Code) signal provides an accurate and secured time transmission. This type of distribution is mainly used in large installations (Airports, Railways) with a long distance between the slave clocks.

Advantage :

- Perfect for large installations including digital clocks in new buildings

- Digital signal coming from the master clock

Time Distribution : NTP

NTP (Network Time Protocol) is a protocol designed to synchronise clocks or equipment (computers...) over a network.

Why is NTP Important?

Time is essential in many applications, especially in those such as Trading Offices, Security Services and Air Traffic Control where precision timing is critical.

Advantage :

- Permits the automatic synchronisation of all the equipment that is connected. The protocol is known and used worldwide.

Bodet analogue or digital clocks utilise ntp over ethernet to continuously display an accurate synchronised time. Our clocks operate with any of ntp time resources, including our Sigma NTP server.

For simplicity of operation, the clocks can be Power-over-Ethernet (PoE) devices.  No mains socket is required, the device is powered from the network jack plug. Installation is therefore very straightforward, and the units can be easily moved, making it a very portable system.

If your network is not PoE enabled, power adapters are available.

Worldwide customers have chosen Bodet solutions for their application :

- Education premises
- Transport (airport, railway)
- Healthcare buildings
- Finance offices ...
