DTD-5230, DTD-5231, and DTD-5233 Installation and Operation Manual
Chapter 3: Operation
Timecode Reader Mode
To operate the DTD-523x strictly as a timecode display, DIP switch
1-6
must be in the
Timecode
(opened) position. When input SMPTE or
EBU timecode is present, the DTD-523x follows it directly: up, down,
or paused.
Timecode Failure
If there is a failure of input timecode, the following occurs:
•
Colon LEDs extinguish
•
Last valid time remains displayed
•
Input timecode does not switch to a secondary reference
Time Display Format
When used in
Timecode Mode
, the DTD-523x always displays time in
24-hour format without AM and PM indications. Using DIP switch
1-1
,
the digits are configured for HH:MM:SS display or MM:SS.FF display.
Secondary Reference Mode
The DTD-523x runs as a standard clock when no input timecode is
provided. To operate the clock in this mode, make these settings:
•
Move the rear panel DIP switch
1-4
to select the time base: The
Internal
(closed) position selects the clock’s internal crystal, while
the
Line
(opened) position selects the power line frequency (50Hz
or 60Hz).
•
Move DIP switch 1-6 to the
Timecode
(closed) position.
•
Move the rear panel DIP switch
1-2
to the
Run on Secondary
(opened) position.
Note
The DTD-523x will still function without selecting
Run On
Secondary
. However, the colon LEDs will flash at the rate of twice
per second to indicate the absence of input timecode.
When in this position, the colon LEDs do NOT flash.
