Note
Except where noted, the term “DTD-523x” is used in this manual to
refer to the DTD-5230, DTD-5231, and DTD-5233 digital time/date
display clocks.
The DTD-523x series are digitally controlled, self-setting clocks. They
operate in one of two modes: Stand-alone mode via power line
frequency or internal crystal, or with an SMPTE or EBU serial timecode
input as either a clock or a timecode reader.
When provided with an SMPTE or EBU timecode source, the
DTD-523x series of clocks are instantly self-setting. In the event of a
power failure, the DTD-523x clocks maintain the correct time internally
via a battery-backed timekeeping memory. If power is restored without
timecode, the clocks will self-set to the correct time as maintained by
the battery backup, and then continue to operate on internal crystal or
power-line time base.
