Frequently Asked Questions


  • If I have a system made up of multiple independent clocks, can I keep it synchronized?

    It is possible to synchronize a single clock by using a GPS kit or to implement centralized synchronizing by using a Master Clock connected to the various devices.

  • In a complex time information system can I have redundancy?

    It is possible to implement a system with two different levels of Master Clocks, with one clock acting as a primary clock (master) and the others, on a secondary level, acting as slaves to the first. When configuring a clock, a primary clock may be specified, as well as an optional alternative clock for synchronization purposes, should the connection to the primary master clock fail.

  • I have a dated clock system that I don't want to change. I need some clocks to install in new rooms. Can I keep the old clocks and purchase only clocks for the new rooms?

    Yes, our newly designed clocks that use the NTP protocol can coexist with pre-existing clocks. There are several master clocks that based on the model are capable of managing one or more impulse lines, so as to synchronize traditional clocks as well as NTP clocks.

  • I would like to install and MCK in a room with an electrical power outlet but no Ethernet available. Can this clock only be powered by PoE?

    In the absence of Ethernet connectivity, is possible to use this device anyway: just use the power supply kit with which it is possible to connect it to a standard 230Vac outlet.

  • Can this device already be synchronized by GPS or do I need to buy the additional GPS 2290/NTP antenna?

    The device can be synchronized via NTP or GPS. However, in the latter case, the MCK must be equipped with the GPS 2290/NTP antenna. Therefore, it is necessary to complete the MCK with this accessory in order to use GPS for synchronizing.

  • What does NTP mean?

    NTP stands for Network Time Protocol. It is a protocol used for synchronizing clocks. Solari's most recent designs use this technology.

  • What does PoE mean?

    PoE is an acronym for Power over Ethernet. This technology makes it possible to use an ethernet cable as a power supply as well.

  • What are the advantages of PoE?

    The advantage is that costs are reduced since it is not necessary to install electric cables to supply power to the system and since it is far more simple and quick to install the system itself. Furthermore, the low-voltage power supply makes this device much safer.

  • Is maintenance necessarily performed directly on the device?

    Not necessarily. Our recently designed devices have an integrated Web server, and therefore configuration and synchronization can be performed remotely, by means of a simple browser. This feature greatly simplifies and speeds up maintenance, especially when the clock' s location is not always easily reached.
