Self-Setting Analog Clocks The ADC-5100 Series clocks are designed to
combine the advantages of large, easily read analog time displays with
the self-setting capability of digital SMPTE/EBU serial time code readers.
This advanced mode is made possible by a unique digitally-controlled
drive mechanism. A microprocessor is used to decode the digital
information and precisely position the hands.
Master Operation
When no source of time code is available, the ADC may be configured as a
time code generator, using its internal quartz crystal. An internal cable
change is all that is required. The secondary reference must be set to
internal, and the time code format DIP Switch must select either SMPTE or
EBU format.
In addition to SMPTE/EBU time code, the clocks can operate on the
internal quartz time base, or from the 50/60 Hz power line. This
three-way reference capability allows easy integration into new or
existing clock systems.
When used as a generator, the ADC can drive multiple high
impedance, time-code-reading devices.
The clocks are available in a variety of sizes for wall- or rack-mounting.
Wall-mount models can be easily adapted to rack-mount. The standard
clock face has two sets of numerals, i.e. 1 ... 12 in black and 13 ... 24 in
red.
Secondary Drives
The internal crystal oscillator or the power line reference may be selected
to provide automatic back-up if time code fails. Either time base can also
be used to run the clock as a stand-alone device, when necessary. The
ADC automatically detects the presence of 50 or 60 Hz power line
frequency.
Time Code Operation
Clock installation is simple when SMPTE or EBU format time code is
available. Apply power, connect time code, and the clock takes care of
the rest.
Battery Back-up
If AC power is lost, the ADC maintains time internally via a crystal
oscillator. Self-setting to this time will occur if no input time code is
available on power-up.
On initial power-up, the clock will start to run at whatever time the hands
indicate. The error LED at the bottom of the clock face is illuminated.
When time code is connected, the processor moves the hands the
shortest distance to the correct time. Once the clock is set, the error LED
is turned off. This process takes less than 15 minutes.
REAR PANEL FACILITIES
If time code fails, the error LED flashes, and the clock automatically switches
to the preselected secondary reference. This can be the internal quartz time
base or power line. Any time discrepancy on return of time code causes the
hands to move directly to the correct position. This also applies to time code
changes, such as Standard Time to Daylight Savings Time.
Time Offsets
The LEITCH CSD-3901 Master Clock System Driver allows programming
of time code user bits. This facility can be used to include a specific time
offset in the time code. The operating mode of one or more ADCs in a
system can then be set to read this offset. A typical application is the
display of GMT in addition to local time.
Additionally, ADCs may be preset to display an offset from local time.
This local offset allows the display of any or all time zones at one
location. This offset is user-programmable.
Primary Drive Connectors .
The rear panel input connectors for
time code are color-coded
(red/black), spring loaded
speaker-type connectors. A
standard three-prong AC receptacle
is also provided.
Mode Configuration A six-position
DIP switch is used to set the clocks
operating modes. The first switch
selects the primary drive. The second switch selects SMPTE or EBU
time code format for use when operating as a generator. The third
switch selects the secondary drive, which will be used if the time code
input fails. The secondary reference may be the internal quartz crystal
oscillator or AC power line. The fourth switch selects either normal
time code operation or time offset (requires time code from
CSD-3901). This allows certain clocks in the system to display a
different time, according to an offset programmed into the user bits of
the time code. The fifth switch specifies whether the clock should run

from the preselected primary or secondary drive. The sixth switch is used
to select a step or sweep second hand. 115 or 230 VAC selection is
made via internal wire jumpers; 50 or 60 Hz detection is automatic.

Manual Setting
When operating in a mode other than time code, the clock can be
accurately set by means of three miniature pushbuttons on the rear
panel. One of the buttons selects the manual set mode. The other two
buttons move the hands clockwise or counterclockwise in appropriate
increments. These buttons are also used to program a local offset
from time code.
