8 UDC-5212 and DTD-5225 Digital Time/Date Display Clocks Installation and Operation Manual
Chapter 1: UDC-5212 Universal Digital Clock
The MTG-3901, CSD-3901/3902, and CSD-5300 Master Clock System
Drivers are real time timecode source, which can program such an
offset into the timecode’s user bits. The offset is programmed in 30
minute intervals up to 23 hours and 30 minutes, using 6 bits of the
timecode’s user bit space.
The offset is encoded using timecode bits 36, 37, 38, 52, 53, and 54. Bit
36 is the least significant bit (LSB), while bit 54 is the most significant
bit (MSB).
When DIP Switch 3 on the UDC-5212 clock is in the USE AUX
OFFSET position, the auxiliary offset found in the input timecode’s
user bits is added to the input timecode. The clock then displays the
total. If no input timecode is available, DIP Switch 3 has no effect. If
the user bits are incorrectly programmed, the offset is disregarded.
A programmed local offset (See -Clock Setting Controls on page 1 of
this manual) is still in effect while using the auxiliary offset. The local
offset is totally transparent to the input timecode’s user bit offset.
If input timecode is removed while USE AUX OFFSET is selected, the
clock will retain the time with the offset added, not the original time.
Date Display
The UDC may display the date on the central digits when used with a
MTG-3901, CSD-3901/3902, or CSD-5300 Master Clock System
Driver. The perimeter seconds LEDs will continue to follow the time
from the input timecode. DIP Switch 2 must be set to the RUN ON
SECONDARY (DATE IF CODE PRESENT) position to activate the
Date display. DIP Switch 1 is used to select the date display format;
either DD:MM:YY or MM:DD:YY may be displayed.
Timecode Generator Mode
The UDC-5212 clock can also function as real time timecode generator,
essentially operating as a master clock. This timecode output may be
used to drive other clocks or Time-Code-reading devices.
To configure the UDC as a timecode generator, an internal connector
must be transposed so that the rear panel speaker-type connectors
become the timecode output terminals.
