Videotek® ADCA12C31
Analog Clock Display
The Videotek® ADC-A12C31 is a precision analog clock containing
a stepper motor drive and advanced, microprocessor-controlled
electronics to provide an accurate delivery of time. The clock is
designed with a powder-coated steel case for wall mount
applications (mounting bracket supplied). The ADC-A12C31
supports LTC using SMPTE timecode. Clear labeling and an internal,
LED-lit face make this clock readable from long distances. Standard
power connection and BNC connection for the LTC are provided.
Features
Battery backup retains time during loss of power or reference
Self-correcting hands once power and/or timecode reference is established and after loss of power and/or timecode reference and DST
changes
Time zone offsets (to one second resolution)
DST (Daylight Savings Time) configuration
TCXO (Temperature Compensated Crystal Oscillator) for ± 1 minute per year accuracy when no reference available (free running)
All configuration settings retained in non-volatile flash memory
Second hand with sweep or step option
Status LED on clock face, located at the 6 o’clock position
Microprocessor-controlled stepper motor for reliable, accurate and quiet operation
Universal AC input voltage and frequency
Fully configurable via USB interface with supplied ADC-SET software
-11.5 to 12 hour time zone offsets in 30-minute increments
Self-correcting to non-drop frame timecode
SMPTE, EBU and IRIG B (modulated and unmodulated) timecode support
