Quick Setup Instructions UDC-5212 and DTD-5225 Digital Clocks
4. Setting the Clock Secondary Reference Source
If the UDC/DTD is set to Clock mode, you can use DIP switch 4 to select the secondary
reference source. If the timecode source fails, the UDC/DTD will use the secondary
reference as the time source. You can select a secondary reference from one of the these
two options:
• INTERNAL The UDC/DTD uses its internal crystal oscillator as the clock
reference source.
To select this option, set DIP switch 4 to the left position.
• LINE The UDC/DTD uses the AC power line frequency as the clock reference
source.
To select this option, set DIP switch 4 to the right position.
5. Enabling Timecode Auxiliary Offset
Using DIP switch 3, you can enable a user-programmed auxiliary offset from the input
timecode user-bits. To use this option, the input timecode source must come from a
MTG-3901, CSD-3901/3902, or CSD-5300 clock system driver.
To enable the timecode auxiliary offset, set DIP switch 3 to right position. To disable the
timecode auxiliary offset, set DIP switch 3 to left position.
6. Setting LED and Date Display
Using DIP switch 2 you can select options for the LED and date display.
• NORMAL When using the this setting, if the input timecode source fails, the
colon LEDs flash twice per second.
• RUN ON SECONDARY When using this setting, if the input timecode source
fails, the colon LEDs stop flashing. If the timecode source is a MTG-3901,
CSD-3901/3902 or CSD5300, the UDC/DTD displays the date.
7. Setting 12 Hour or 24 Hour Display
Using DIP switch 1, you can set the UDC/DTD display to either 12 hour or 24 hour
display.
• 12 HOUR When in Clock mode, the clock displays time in A.M. and P.M time
convention. When the clock is in Timecode Reader mode and DIP Switch 2 is set to
the left position (NORMAL), the clock displays timecode as HH:MM:SS. When
the clock is in Timecode Reader mode and DIP Switch 2 is set to the right position
(date if code is present), the clock displays timecode as DD:MM:YY.
To select this option, set DIP switch 1 to the left position.
• 24 HOUR When in Clock mode, the clock displays time in 24 hour time
convention (00—23 hours). When the clock is in Timecode Reader mode and DIP
Switch 2 is set to the left position (NORMAL), the clock displays timecode as
MM:SS:FF. When the clock is in Timecode Reader mode and DIP Switch 2 is set to
the right position (date if code is present), the clock displays timecode as
MM:DD:YY.
To select this option, set DIP switch 1 to the right position.
