The ADC-A12C31 does not support decoding of SMPTE drop-frame, reverse running, VITC,
NTSC, color frame, blackburst or other video time code formats and synchronization options.
Please refer to the “Specifications” section of this document for additional details.
Introduction
The ADC-A12C31 is a precision analog clock containing a stepper motor drive and advanced
microprocessor controlled electronics.
IRIG-B
Defined by the Range Commanders Council, U.S. Army White Sands Missile Range. IRIG (Inter-range
Instrumentation Group) is used by military, government, power industry and many other commercial
and industrial applications. The ADC-A12C31 decodes IRIG-B in both a 1 kHz modulated (IRIG-B1) and
un-modulated/pulse width coded/DC level shifted (IRIG-B0) format. All formats of IRIG-B time code
decoded by the ADC-A12C31 use the time of year information BCD (Binary Coded Decimal). All
formats of IRIG-B time code decoded by the ADC-A12C31 also use the extended year/date and time
zone information in the control functions as defined by the IEEE 1344 specification. SBS (Straight
Binary Seconds) information is not decoded. Manchester format/encoding is not supported.
The ADC-A12C31 can be configured for world-wide time zone offset and automatic DST
(Daylight Saving Time) adjustment and allows for reliable, accurate and maintenance free
operation. Use of the automatic DST feature requires that the clock be enabled to accept the
time code date encoding, using the USB port and ADC-Set (Clock Time Code Display) USB
Configuration Utility (i.e. Windows software application). The time code reference must
provide date encoding in the control bits/fields to date encoding standard for SMPTE or the
IEEE-1344 year encoding for IRIG-B.
SMPTE
Society of Motion Picture and Television Engineers format is available in frame rates of 24, 25, and
30 frames second. The ADC-A12C31 time code clock supports all three formats. All formats of
SMPTE time code decoded by the ADC-A12C31 use the full date information in the user bits as
defined by the standard.
Features
RTC (Real Time Clock) backup retains time during loss of power or reference.
Self-correcting hands once power and/or Time Code reference is established.
Time zone offsets
DST configuration.
TCXO (Temperature Compensated Crystal Oscillator) for +/- 1 min per year accuracy when
no reference available (freewheeling).
All configuration settings retained in non-volatile flash memory.
Second Hand with sweep or step option.
Self-correcting hands after loss of power and/or time code reference and DST changes.
Loss of LTC status LED on clock face, located at the 6 o’clock position.
ADC-A12C31 Operator’s Handbook Rev. A P. 9

LED STATE
STATUS INDICATION
Off
The clock acquired valid time code and has synchronized its internal
RTC to the time code reference. The internal clock time is considered
accurate. The clock hands may be adjusting/correcting rapidly either
clockwise or counter-clockwise during a correction.
On Solid
The clock is not able to decode the time code reference or the
reference is not present. Time displayed on the face of the clock is
based upon internal and TCXO and should not be considered
accurate.
Operating Environment
The ADC-A12C31 clock contains a stepper motor and microprocessor control electronics designed to
operate indoors between 32˚ to 140°F (0˚ to 60˚C) with 0-90% relative humidity, non-condensing.
Operation
After applying power, the clock will go through an internal check. Time from the RTC backup will be
applied until a Time Code reference is acquired.
During this period the red status LED will be on solid and the hands will move in either a clockwise or
counter clockwise motion.
Status LED
The red LED on the ADC-A12C31 clock face, located at the 6:00 indicates;
Correction Behavior
The correction cycle engages when there’s a change to the internal RTC as compared to the time
code reference.

Reset Device
ADC-A12C31 Operator’s Handbook Rev. A P. 15
The hands of the ADC-A12C31 cannot be set manually. Do not attempt to open the clock to
access the hands. This action will void your warranty. This device has no user serviceable
parts inside.
Please refer to the “Configuration” section of this document for additional details on
how to adjust the settings.
If the configuration software is used to configure the clock, the DIP switch settings will
be ignored. In order to restore the configuration mode to the use of the DIP switches,
the unit must be reset to factory default. (As shown on page 22)
If the time code input to the ADC-A12C31 is not UTC, do not adjust the time zone and/or
DST offset.
The incoming time code must have the date encoded in a format recognized by the ADCA12C31 for DST adjustments to be performed. For best reliability Imagine Communications
Corporation recommends a time code reference that encodes full date information.
Hand Position
The hands will set (adjust) to the time code reference, plus any time zone and/or DST offsets.
If for any reason the clock hands become slightly out of alignment, a calibration setting function has
been provided in ADC-Set configuration utility or using the buttons located on the back.
The ADC-A12C31 series can be configured using one of the following methods:
DIP Switches and buttons.
ADC-Set, USB Configuration Utility via the USB port.
Time Zone Offsets
All time code analog clocks maintain time as UTC.
A time zone offset can be used to adjust the time for display purposes. The can be set as a positive (+)
offset indicating that the unit leads the UTC time or negative (-) offset value indicating the unit lags
behind UTC time. An offset with a resolution of one half hour (via DIP switches) or 1 second (via ADCSet configuration utility) can be achieved.
Daylight Saving Time
An automatic DST setting can be configured separately and in addition to a time zone offset.
For SMPTE time codes, date must be encoded to the specification. IRIG-B date decoding is supported
for the IEEE 1344 standard.
ADC-A12C31 Operator’s Handbook Rev. A P. 16
To ensure proper hands-free year-around operation, DST adjustments must be configured
using the daylight time option and not with the time zone offset option.
The ADC-A12C31 analog clock provides flexible configuration options supporting most world DST
standards.
Pre 2007 Standard – U.S.A. and Canada
Traditional US/Canada daylight/summer time is configured as one (1) hour positive offset.
For the U.S. (through 2006) and Canada, daylight savings time begins on the first Sunday of
April at 2:00AM (Local Time) and ends on the last Sunday of October at 2:00AM (Local
Time).
Post 2006 Standard – U.S.A. and Canada
On August 8, 2005, the Energy Policy Act of 2005 was signed. This Act changed the time
change dates for Daylight Saving Time in the U.S, effective in 2007. DST now begins on the
second Sunday of March at 2:00 AM (Local Time) and end the first Sunday of November at
2:00 AM (Local Time).
EU Standard – European Union
In the European Union, daylight change times are defined relative to the UTC time of day
instead of local time of day (like in the U.S.). For the European Union, summertime period
begins at 1:00 AM UTC on the last Sunday of March and ends at 1:00 AM UTC on the last
Sunday of October. Please carefully consult the section entitled “Device Settings” for details
on setting daylight time.
Freewheeling Accuracy
The ADC-A12C31 has built-in provisions to allow the clock to freewheel and maintain accuracy for
extended periods in the absence of time code. These features also allow the unit to be set manually
and operate without time code.
TCXO and RTC circuit
The ADC-A12C31 contains a precision TCXO and RTC circuit allowing the clock to maintain an
accuracy of +/- 1 minute per year to the last known time code input (+/- 165 mS per day)
when time code is not preset or cannot be decoded (i.e. freewheeling mode).
Maintenance-free Rechargeable Battery
The RTC and TCXO are maintained continuously from a rechargeable battery circuit during
periods of power outage. Minimum holdover period is two weeks once the battery is
charged. The battery will automatically charge when the unit is next powered and requires
no maintenance.
Non-Volatile Configuration
The clock configurations are maintained in non-volatile memory allowing the current settings to be
retained during power outages.

The visual determination of the accuracy of the hand display should be done by comparing
the clock hands only after the ADC-A12C31 indicates that it is synchronized to time code and
then only to a digital display or other reference that has also been locked, preferably to the
same time code reference. The reference display should be set adjacent to the ADC-A12C31
unit and eye movements should be minimized when doing comparisons.
After releasing the button, the hands will rotate in the desired direction until any button
is pressed. This feature allows for easier setting of the hands.

USB Device Drivers
A USB type B port has been included on the rear cover of the clock to provide a means of configuring
the clock via software and to allow for firmware upgrades for either firmware corrections or future
product enhancements.
To utilize the USB port, connect a USB type A to USB type B cable from the computer to the clock.
Installing the Device Driver
First, power-on the ADC-A12C31. Next, use a USB cable (not supplied) and connect to the PC.
The Windows Plug and Play manager will detect a new USB device and request device drivers. If
Windows is unable to install the USB device drivers, the system will send an alert.
Open “Device Manager” and locate “Time Code Display” listed under “Other devices”.
Right click the device and click on “Update Driver Software”. This will need to be
performed for both USB device drivers (i.e. COM and BUS).
There are two locations for the USB Device Driver:
1. C:\ Program Files\Imagine Communications Corporation\ ADC-A12C31\Drivers\
2. CD labeled, “Clock Products” X:\ADC-A12C31\Drivers\
Note: “X” is the CD/DVD drive letter of your Windows PC.
ADC-A12C31 Operator’s Handbook Rev. A P. 26
The ADC-A12C31 can be configured to display local time using time zone offsets and DST
settings. These offset changes are made relative to UTC time. The clock always interprets
the incoming time code as UTC.
Using ADC-Set, USB Configuration Utility
Open ADC-Set from the “Start Menu” or by double-clicking the shortcut icon on the desktop.
The top left section of the main window shows the firmware version and serial number of the
clock. Located below this information is the current status of the clock display, this information is
constantly updated. The Local Time is the time displayed on the clock face, including any time
zone or DST offset information.
The UTC Time is the internal time reference derived from the incoming time code and treated as
UTC. This display update is not precise, but is meant to give you a view of the clock display time
for basic troubleshooting and maintenance purposes. Also included is a Time Code Status which
displays the type of incoming time code and/or the synchronization status.
The brightness level of the clock face is controlled by sliding the “Illumination” bar or using the
DIP switches located on the back of the clock.
The [Time Zone] and [Daylight Saving Time] buttons on the right half of the window, give the
clock complete flexibility to set and display any time zone and worldwide DST combination.

you a list of time zones, including descriptions to help with the selection. Select the desired time
zone and click [OK] to close the window. Changes are applied when you click [OK].
Daylight Saving Time
Configure and/or enable the daylight saving function by clicking the [Daylight Saving Time]
button. North American and European Union DST settings are quickly entered by clicking the
appropriate button; [US\Canada Standard] or [EU Standard].

ADC-A12C31 Operator’s Handbook Rev. A P. 28
Time Code Settings
To use the automatic DST adjustments requires that date/year encoding is enabled.
This product contains an automatic detection and gain control circuit for the incoming SMPTE
30/25/24 fps longitudinal/linear time code or for IRIG-B(0) pulse width modulated or IRIG-B(1)
amplitude modulated time code.
To support common SMPTE/IRIG-B standard time codes without date/year encoding to the
aforementioned standards, an option of ignoring the date information encoded in the time code is
provided.
ADC-A12C31 Operator’s Handbook Rev. A P. 29
Practical use of this feature requires the clock to be removed from the time code
reference.
When the clock has access to a valid time code reference, information obtained via
time code will immediately overwrite any manually established time/date.
Set Date Time
The [Set Date Time] feature lets you manually set the time and date for the clock. This may be
most useful for lab situations as the clocks keep time via their internal precision oscillator and
real-time clock when time code is not present. The time can either be set to the time of the PC or
a manual time and date can be entered.
Clock Hand Position
The Clock Hand Position button provides two functions.
Allows the user to calibrate or fine tune the hands of the clock
Set the second hand mode function from sweep to step mode.
ADC-A12C31 Operator’s Handbook Rev. A P. 30
You can check the new settings with a digital display reference at this point to ensure
that the hands have been correctly set.
Sweep mode
Sweep mode is the default mode and displays a continuous second-hand smooth motion.
Step mode
The step mode motion is similar to the motion of a quartz clock. The hand will pulse in one-second
intervals.
To adjust the hands
1. Click [Clock Hand Position] to enter the alignment window.
2. Select the box, “Check to set clock”.
3. Enter the correct hour, minute and second currently displayed on the face of the clock.
If the second is not currently aligned on a second mark, you can nudge the second hand
forward incrementally by clicking [Forward].
4. Click [OK] to accept the new settings.
The new hand alignment settings will be stored in non-volatile flash. The clock hands will adjust to the
new settings and display the time after several moments.

Troubleshooting
The time is incorrect.
Red status LED is always on.
Possible reasons/solutions:
1. The ADC-A12C31 is not currently connected to a valid time code reference.
2. There is a problem with the cabling between the ADC-A12C31 and the time code reference. Verify
that all cables and connectors are in good condition.
3. There is a ground loop or other type of interference between the ADC-A12C31 and the time code
reference. Verify that a common ground exists between the ADC-A12C31 and the time code
reference. If the cabling distance between the time code reference and the ADC-A12C31 is large
you might consider inserting an audio distribution amplifier or an Imagine Communications
Corporation TCA100 time code amplifier in-line.
4. The signal level of the incoming time code is out of the range of the ADC-A12C31’s time code
decoder’s circuitry. See the ADC-A12C31 specification section for acceptable signal level ranges.
5. The time code reference, to the ADC-A12C31 is not a recognized format. Verify that your time
code reference is providing one of the time code formats that the ADC-A12C31 can decode.
Not displaying the correct [local] time.
Possible reasons/solutions:
1. The unit is not receiving time code. Verify that the front LED status indicator is off.
2. The time code reference is referenced to UTC but your local time zone has not been configured.
3. Your DIP switch settings for DST may have been overridden by ADC-Set configuration utility.
4. You may be seeing the result of a double offset. Determine the time zone reference of your time
code reference and then set the ADC-A12C31’s time zone offset to arrive at a correct local time.
If the time code reference is already providing time code with local time zone and/or DST
offsets, then set the time zone and/or DST offset of the clock to UTC.
If the time code reference is providing UTC time code, then configure your clock to have a
local time zone and/or DST offset.
5. Your time code reference is not providing the time/date that you expect. Contact the individual
responsible for the time code reference for more information.
ADC-A12C31 Operator’s Handbook Rev. A P. 35
There are no user serviceable parts inside the ADC-A12C31 analog clock.
Please contact Imagine Communications Corporation if you require servicing or repair.
Displayed time [local] is off a small amount.
Possible reasons/solutions:
1. Perception/recognition response time. The average human ability to visually perceive and
recognize time synchronization and/or instantaneous change between two visually separated
systems is limited due to the movement of the eyes and the delayed response to process the
data. To reduce this effect:
Place a digital display adjacent to the clock you are trying to verify the time on.
View the clocks from a position that will avoid eye movements.
Ensure that both clocks are locked to an accurate time code reference.
Ensure that both units have the same offset settings for time zone and/or DST.
2. ADC-Set configuration utility’s screen display is a GUI (Graphical User Interface) that is not being
run at the highest priority level for the system. There will likely be a delay in processing the data
and updating the screen, therefore it should not be considered an accurate reference.
3. Ensure that you are not using Drop-Frame SMPTE time code. Drop-Frame time code is not
supported. Accurate time cannot be guaranteed with drop-frame time code.
4. The clock hands have been incorrectly calibrated with either the calibration buttons or ADC-Set
configuration utility. See the calibration procedure for details on how to recalibrate the hands.
DST is not properly negotiated.
The date shown in the status window of ADC-Set configuration utility is always 01/01/2000.
Possible reasons/solutions:
1. Your time code reference is not providing date/year information. The DST adjustment will not
work unless valid date information is provided. Verify that your time code reference has either
date encoding to the SMPTE standard for SMPTE time code or year/date encoding to the IEEE
1344 specification for IRIG-B/B1 time code.
2. The TC control DIP switches S2-1 and S2-2 have both been set to off and/or the time code date
encoding has been disabled in the ADC-Set configuration utility.
3. Your time code reference already provides the DST adjustment. The DST adjustment in the ADC-
A12C31 should be disabled.
4. You have disabled the DST setting or the incorrect DST setting was enabled. The ADC-A12C31 has
DIP switches for enabling various modes of DST or disabling the DST option. In addition to the DIP
switches, the ADC-Set configuration utility may be used to set the DST settings as well as all
configuration settings of the clock. If the ADC-Set configuration utility is used, it will over-ride the
DIP switch settings.
The clock hands are not moving and the red status LED is off.
Possible Reasons/solutions:
1. The clock does not have power applied.
2. The Run/Set switch is in the SET position or the ADC-Set configuration utility is being used.
3. The internal power supply or the motor/motor drive has failed.

Care and Cleaning
Adherence to regular and proper cleaning procedures is recommended to preserve appearance.
Scratched or otherwise damaged lenses caused by misuse, mishandling, and improper storage or
improper cleaning is not covered under the limited warranty.
Job Site Precautions
It is recommended the clock be removed from the wall and stored face up in its protective shipment
bag during painting and construction.
New construction and renovations frequently require that the job site be cleaned of any excess
mortar, paint, sealant, primers or other construction compounds. Only recommended cleaners
should be used to clean the polycarbonate lens. Contact with harsh solvents such as methyl ethyl
ketone (MEK) or muriatic acid can result in surface degradation and possible crazing of the
polycarbonate.
When the clock is first installed, glazing compound and masking tape adhesive can be easily removed
from the lens by applying naphtha (VM&P) or kerosene with a soft cloth, followed immediately with a
thorough soap and water cleaning.
Stainless Steel Case
If your clock has a stainless steel case, a cleaner and polish designed for use on stainless steel is
recommended. Use a recommended product to maintain and protect the stainless steel finish while
resisting water spots and fingerprints.
Compatible Cleaners & Polish
The following cleaning and polish agent has been found to be compatible with the
stainless steel case finish. Manufacturer's instructions should be followed.
Magic® Complete™ Stainless Steel Cleaner & Polish Spray (Magic American Products.
Washing to Minimize Scratching
Wash with a mild soap or detergent (such as 409™ (Clorox Co.), cleaner) and lukewarm water, using a
clean sponge or a soft lint free cloth. DO NOT USE PAPER TOWELS OR PAPER PRODUCTS TO CLEAN OR
DRY THE LENS. Rinse well with clean water. Dry thoroughly with a chamois or moist cellulose sponge
to prevent water spots. Do not scrub or use brushes or abrasives on these products; the UV coating is
not mar resistant. Also do not use butyl cellosolve in direct sunlight.
Fresh paint splashes, grease and smeared glazing compounds can be removed easily before drying by
rubbing lightly with a good grade of naphtha or isopropyl alcohol. Follow the alcohol rub with a mild
detergent wash with warm water and end with a thorough rinsing with clean water using a clean
damp lint free cloth.
ADC-A12C31 Operator’s Handbook Rev. A P. 37
Minimize Hairline Scratches
Always store the clock face-up in the protective plastic shipping bag until ready for installation and
during transporting to the installation site. Do not place the clock face (lens surface) down on any
surface as this may scratch or mar the lens.
Scratches and minor abrasions can be minimized by using a mild automobile polish. Three such
products that tend to polish and fill scratches are Johnson Paste Wax, Novus Plastic Polish #1 and #2,
Novus, Inc., Minneapolis, MN and Mirror Glaze plastic polish (MG M10) Mirror Bright Polish Co.,
Pasadena, CA. It is suggested that a test be made on a very small section of the polycarbonate lens
with the product selected and that the polish manufacturer's instructions be followed.
"Don't" - Very Important
Don't store the clock without the protective plastic shipment bag.
Don't store or place the clock face down on any surface, as this may scratch the lens.
Don't use abrasive or highly alkaline cleaners.
Don't use paper towels, paper products, rayon or polyester cloths to clean or dry the lens.
Don't scrape the lens with squeegees, razor blades or other sharp instruments.
Don't ever use benzene, gasoline, acetone, methyl ethyl ketone (MEK), muriatic acid or carbon
tetrachloride on the lens.
Don't clean lenses in hot sun or on very hot days.
Cleaning the Lens
The following cleaning agents have been found to be compatible with the Polycarbonate and Acrylic
lens. Manufacturer's instructions should be followed. Formula 409™ (Clorox Co.), Top Job™ (Proctor
& Gamble), VM & P grade Naphtha Joy™(Proctor & Gamble), Windex w/Ammonia D™Drackett
Products), Palmolive Liquid™(Colgate Palmolive).
Foreign Substance Removal
Butyl Cellosolve (For removal of paints, marking pens, lipstick, etc.)
The use of adhesive tape or lint removal tools work well for lifting off old weathered paints.
To remove labels, stickers, etc., the use of kerosene, naphtha or petroleum spirits is generally
effective. When the solvent will not penetrate sticker material, apply heat (hair dryer) to
soften the adhesive and promote removal. Gasoline should never be used.
