Product Manual

The 1200T series Analog Clock Displays take master and slave clock technology to new levels of convenience and excellence. The clocks are microprocessor controlled and employ separate direct drive motors for each hand. This means that, as well as being able to set the time almost instantaneously, the new displays are also silent in operation. The hands of the clocks can be programmed to move in sweep mode or in steps.

Each clock can be programmed for automatic Daylight Saving Time adjustment, as well as for any time zone offset using a laptop computer. It is then only necessary to supply the clock system with Universal Coordinated Time (UTC) from the master clock. Daylight Saving Time changes will be automatic, as will adjustments for different time zones.

Each clock can be used as a master or slave clock. When used as a slave clock, it reads SMPTE linear timecode (LTC) from a master clock. When used as a master, it generates LTC for distribution to other slave clocks. In fact, any clock in the chain can generate timecode as soon as it loses timecode input from the master. The system is therefore extremely robust and reliable.

When the +T option is added, the 1200T series clocks can lock to time distributed as Network Time Prototcol (NTP) over Ethernet.

The problems of power distribution have also been considerably simplified. With other clock products, it is necessary to install power outlets wherever clocks are to be located. The 1200T series system slave clocks are powered from the Ethernet cable that distributes both power and NTP time. The clocks may also be powered locally using the AC to 12V DC adapter provided.

Internal crystal oscillators ensure that the clocks will continue to operate in the absence of input timecode. Internal battery backup ensures that each clock will continue to keep time in the absence of timecode and power. When power resumes, the hands will immediately reset to the correct time.

The 1200T series clock displays are offered in two sizes. Backlighting is available for all models.
