TimeTools digital wall clock time displays utilise NTP over ethernet to display a continuously accurate synchronised time.

The synchronised time displays are available as four-inch high numerals with four or six digits. The large wall clock obtains time from an intranet or internet based NTP server, to provide an accurate time display to one-fifth of a second.

The Ethernet NTP digital wall clock operates with any of NTP or SNTP time resource including TimeTools NTP server products. The unit can also utilise internet based time sources, such as NIST.

For simplicity of operation, the units are Power-over-Ethernet (PoE) devices (IEEE 802.af) using the same network components as IP telephones. If required single or multi-port PoE injectors can be provided at a very reasonable cost.

The large digital wall clock plug into an Ethernet jack on your local area network. No mains socket is required, the device is powered from the network jack plug. Installation is therefore very straightforward, and its easy to move the units around.

The devices are powered over the standard CAT5 cabling using Power-over-Ethernet (IEEE 802.af), the same ethernet standard as voice-over-IP telephones. If your network is not PoE enabled, single or multi-port mid span converters (power injectors) are available at very low-costs.

The digital wall clocks are highly accurate, requiring no human intervention. All time updates are performed automatically using SNTP over the network. No special hardware or software is required. The devices can automatically detect available NTP time servers on the network.

Additionally, you can configure and control hundreds of clocks from any PC on your network using a simple telnet session.
