DTD-5230, DTD-5231, and DTD-5233 Installation and Operation Manual
Chapter 1: Introducing the DTD-523X Clock Series
DTD-523x clocks automatically decode either SMPTE or EBU
timecode inputs. Additionally, these clocks function as timecode
generators when operated from their internal crystals. Either SMPTE or
EBU timecode can be generated and used to drive other clocks.
When driven from the MTG-3901 Master Time Generator or
CSD-3901/3902 Clock System Driver, DTD-523x clocks are
compatible with a user-defined auxiliary time offset and date. Some
abilities are as follows:
•
Local offset can also be programmed up to 23:59:59.
•
Time display can be either
12-
or
24-hour
format, and can display
HH:MM:SS or MM:SS.FF.
•
Dates can be displayed as month:day:year (MM:DD:YY) or
day:month:year (DD:MM:YY).
In the event of a timecode input failure, the colon LEDs flash at the rate
of twice per second. DTD-523x clocks then automatically switch to the
user-selected secondary time base, either power line frequency or
internal crystal. (The power line frequency is automatically determined
during power-up.)
If timecode operation is not required, DTD-523x clocks may be set to
use the secondary time base permanently, and the colon LEDs will not
flash.
If operated as a timecode reader display, DTD-523x clocks continually
track the input code, and then stop when the input fails. The colon
LEDs extinguish when timecode is absent in this mode.
The digital time/date display clocks are available in rack-mount (1 RU)
or desktop versions.
