Automatic Time Adjustment

The digital clocks utilize the NTP protocol to maintain accurate time. They can synchronize to any local or internet NTP or SNTP time server. A Windows server can also be configured to provide NTP to the clocks. TimeTools also has a range of GPS referenced NTP servers that can be used as master clocks.

The clocks adjust automatically for Daylight Saving Time, no manual intervention is required, saving time and money.

Power-over-Ethernet (PoE)

Industry standard Power-over-Ethernet (PoE) allows data and power to be provided to the clocks over a single CAT5 network cable. A mains outlet is not required, simplifying installation and reducing costs.

Clock Mounting Options

Two keyhole cut-outs on the rear panel of the clock make mounting on a flat surface or wall simple.

Warranty and Support

  • 12-month warranty.
