The 1200DD & 1201DD are LED digital clocks with 7-segment-digits display. They may operate as a timecode-reading clock or as a SMPTE ST 12-1 linear timecode reader, simply displaying the input timecode. In addition to SMPTE ST 12-1 timecode, the clocks can operate on the internal quartz time base from IRIG-B, a GPS antenna or NTP. This multi-way reference capability allows easy integration into new or existing clock systems.
The model 1200DD clock face has 2.25" tall digits that may display HH:MM:SS AM/PM or HH:MM:SS FF, depending on the control settings. The model 1201DD clock face has 1.00" tall digits that may display HH:MM:SS AM/PM or HH:MM:SS FF depending on the control settings. The brightness of the digital LEDs is adjustable.
Clock installation is simple when one of the time sources is available. Apply power, connect time, select the input source and the clock takes care of the rest, instantly setting to the correct time. If time source fails, the colons flash twice per second to signal it's absence. Any time discrepancy on return of timecode is instantly corrected. This also applies to timecode changes such as Standard Time to Daylight Savings Time.
The 1200DD series displays may be preset to display an offset from local time. This local offset allows the display of any or all time zones at one location. This offset is user-programmable from -12 hours to +12 hours. When no source of timecode is available, the 1200DD & 1201DD may be configured as timecode generators, using their internal quartz crystal. When used as a generator, the 1200DD series displays can drive multiple high impedance, timecode-reading devices.
If AC power is lost, the 1200DD series displays maintain time internally via a crystal oscillator powered by a lithium battery. The display will show this time if no input time source is available on power up.
The rear panel input and output connections for timecode are XLR connectors. The IRIG-B input is a BNC and the NTP is a RJ-45 Ethernet connector. The GPS input is a DB9 connector. The GPS feature requires the +GP option to be purchased. When operating with no time source, the clock time can be easily set by means of three miniature pushbuttons on the front panel, which are also used to control the setup menu.
