5000/5100 Series Digital Analog Clocks Installation and Operation Manual 1

Chapter 1: DAC-5000 Series Digital Analog Clocks

Introduction

The DAC-5000 Series Digital Analog Clocks feature a quiet, digitally
controlled drive mechanism. Each hand is driven independently by a
separate motor and drive train. The exact position of each hand is
microprocessor controlled and virtually error free.

The standard clock face provides two sets of numerals: 1 to12 are black,
and 13 to 24 are red. A clock face with only black numerals from 1 to
12 is optional.

The DAC-5000 Series clocks operate with standard drive signals and
consequently can be easily integrated into new or existing systems.
Selection of the drive signals is made by switches located on the back
panel. The usable drive signals are:

• Serial Timecode (SMPTE or EBU)

• 12 VDC Impulse Clock

• Internal Time Base

• Line Frequency Reference

All clock models accept Serial Timecode are in either the SMPTE or
EBU format.

If reception of the timecode is lost, the error LED located on the clock’s
face will light up and the clock will automatically switch to either the
Internal Time Base or the Line Frequency Reference, as selected on the
back panel switches, without interruption of its operation.

The Internal Time Base is provided by a 4.9 MHz crystal oscillator. The
Line Frequency Reference uses a 50/60 Hz power line. Selection of
either 50 or 60 Hz is made by soldering a jumper on the 5000DL Drive
Logic module.

The following models are available:

• DAC-5016 16 inch illuminated, wall mounting. Rack mounting
kit optional.

• DAC-5012 12 inch illuminated, wall mounting. Rack mounting
kit optional.

• DAC-5008 8 inch illuminated, wall mounting. Rack mounting kit
optional.

• DAC-5006 5 inch non-illuminated, rack mounting.

• DAC-5005 5 inch non-illuminated, desk top.

Calibration of the Internal Time Base

This procedure is used to adjust the frequency of the 4.9152 crystal
oscillator. The accuracy of this adjustment directly affects the accuracy
of the Internal Time Base. The only equipment required is a high
resolution frequency counter.

Connect the frequency counter to the clock test point provided at pin 9
of the CMOS NSC800N Microprocessor IC11. Adjust the 6-25 pF
trimmer capacitor connected to pin 11 of IC11 until the counter
indicates 2.457.600 Hz. It is recommended to use the longest sampling
time possible.

8 5000/5100 Series Digital Analog Clocks Installation and Operation Manual

General Operation

Clock Control Modes

Primary Reference Mode

The Primary Reference Mode provides two options, the Timecode and
the Impulse Clock modes. Selection of either mode is done by switch
SW1.

Timecode Mode

No setting of time is required when the timecode mode is selected.
However, selection of either SMPTE or EBU format should be made by
means of switch SW2.

Upon selecting Timecode mode, the microprocessor will start reading
the code and will light the error LED of the clock face (found under the

6) to indicate that the unit is not yet synchronized with the timecode.

Chapter 1: DAC-5000 Series Digital Analog Clocks

Once the timecode is decoded, the clock hands will move in a clockwise
direction towards the 12:00 position where the three hand detectors are
located. The clock hands will then move to their new position via the
shortest route and the error LED will go off to indicate that the unit is
synchronized with the timecode.

If there is a change in the timecode, the error LED will activate again
while the microprocessor verifies the code to ensure that there is a valid
time change and not a transient condition. This verification requires 30
consecutive full code frames or 1 second for SMPTE format operation,
and 1.2 seconds for EBU format, depending on the selection of switch
SW2. Once the verification is completed and if there is a valid change,
the clock hands will move to the new time position as previously
described and the error LED will go off.

If the timecode is lost due to a mechanical failure such as a
disconnected cable or to a malfunction of the master clock, the error
LED will light up again. The clock, however, will continue to operate
and show accurate time since it will automatically switch to the
secondary time base selected by switch SW3 (either the line frequency,
or the internal crystal oscillator). Once the malfunction is eliminated the
clock will automatically switch back to timecode and re-synchronize to
the incoming timecode, and the error LED will go off.

5000/5100 Series Digital Analog Clocks Installation and Operation Manual 9

Chapter 1: DAC-5000 Series Digital Analog Clocks

Impulse Clock Mode

The DAC-5000 Series clocks will emulate a standard impulse clock.
Like any impulse clock, it must be manually set to the correct time and
will stop if the impulses from the master clock also stop. The unit will
check the polarity of the pulses so that the positive pulses from the red
input connector on the rear panel will move the second hand to an even
number of the clock face (i.e. 2, 4, 6 etc.), while the black input
connector will handle the odd numbers.

This check will only occur after the position of the second hand is
known by the microprocessor. This takes place when the hand passes
the detector located near the 12:00 position.

Correct hand position will be established automatically by the
microprocessor when the clock hands pass their detection positions.
However, to establish the minute hand, the position of the second hand
must be already established. To establish the hour hand, the position of
both the minute and second hands must also be established.

The error LED will not be on when operating as an impulse clock.

Secondary Reference Mode

The DAC-5000 Series clock will run as a standard wall clock with no
exterior Timecode or Impulse drive when selected by the run on
secondary switch SW5. Selection of either Internal reference or Line
frequency is done by switch SW3. Correct hand position is established
in the same manner as for the Impulse Clock. The time must also be set
manually.

The error LED will not be operational when this mode is selected.

Clock Setting Controls

Manual Setting

The clock is manually set by means of three push-buttons located on the
rear panel.

• MANUAL SET Press this button once to select the hour hand,
twice to select the minute hand, three times to select the second
hand, and four times to set the clock. When selected, the hands will
start shaking briskly to visually indicate their status.

Chapter 1: DAC-5000 Series Digital Analog Clocks

• CCW This button moves the selected hand counter-clockwise

one unit. When the time is set, press the MANUAL SET button (a
fourth time) and release it at the exact time that the clock is to be
set. The clock will now return to normal time keeping with the
second hand advancing one second after the

MANUAL SET button

is released.

• CW Press this button to move the selected hand clockwise one

unit. When the time is set, press the MANUAL SET button (a
fourth time) and release it at the exact time that the clock is to be
set. The clock will now return to normal time keeping with the
second hand advancing one second after the MANUAL SET
button is released.

The

USE OFFSET function allows the addition of a user programmed

constant offset to the user bits of a standard timecode. Therefore, the
availability of a timecode generator capable of programming the user
bits of the timecode is essential.

This function is generally used when it is desired to simultaneously
provide GMT and local time with two clocks being fed the same
timecode.

The

USE OFFSET function is selected by closing the control mode

switch SW4 of the rear panel. Six bits of data are used to specify the
offset. The six bits are divided into two three bit sections. The first three
bits follow the unit minutes at bits 36, 37 and 38 of the timecode. The
second three bits follow the unit hours data at bits 52, 53 and 54. The
minimum offset allowed is 30 minutes. This can be incremented in 30
minute periods until reaching 23 hours and 30 minutes which is the
maximum offset allowed.

Chapter 2: ADC-5100 Series Analog Digital Clocks

Introduction

The ADC-5100 Series Analog Digital Clocks are a group of quiet,
digitally controlled, self-setting analog face clocks. These may operate
either stand-alone via power line frequency or internal crystal, or with a
SMPTE or EBU serial timecode input.

When provided with a SMPTE or EBU timecode source, the ADC
Series Clocks are self-setting. If the timecode is valid, the ADC Series
Clocks will advance or reverse their hand positions to the correct time.

In the event of a power failure, the ADC Series Clocks maintain the
correct time internally via a battery-backed timekeeping memory. If
power should be restored without timecode, the ADC Series Clocks will
self-set to the correct time as maintained by the battery backup, and
then continue to operate on internal crystal or power line timebase.

The ADC clocks may operate with either a sweep or step second hand,
and will automatically decode either SMPTE or EBU timecode inputs.
Additionally, the ADC may function as a timecode generator when
operated from its internal crystal. Either SMPTE or EBU timecode may
be generated and used to drive other clocks (in Master Mode).

Note

Internal connector ‘P1’ must be reversed for Master Operation.

The ADC Series clocks are compatible with a user-defined auxiliary
offset when driven from the following clock system drivers;

• MTG-3901 Master Timing Generator

• CSD-3901/3902 Master Clock System Driver

• CSD-5300 Master Clock System Driver.

A local offset can also be provided by electronically re-positioning the
clock hands.

In the event of a timecode input failure, an error LED (located on the
clock face under the 6) will flash at the rate of twice per second. The
ADC clock will then automatically switch to the user-selected
secondary timebase, either power line frequency or internal crystal. The
power line frequency is automatically determined during power-up. The
error LED will illuminate during power-up to indicate 50 Hz power line
frequency detection.

Chapter 2: ADC-5100 Series Analog Digital Clocks

If timecode operation is not required, the ADC clock may be set to use
the secondary timebase permanently, and the error LED will be
extinguished.

Reference input (i.e. SMPTE Serial Timecode or Impulse Drive
signals). Note that the correct polarity (i.e. red-to-red) is not required.

There is an indicator along the left side of the clock rear panel noting
whether the clock is in “MASTER” or “SLAVE” configuration. All
clocks are shipped configured for timecode input (slave) operation,
unless otherwise specified when ordering. The clock type and operating
voltage are also indicated on the rear panel.

A standard AC connector for the power feed of the unit can be found in
the recessed area running across the middle of the rear panel.

Chapter 2: ADC-5100 Series Analog Digital Clocks

General Operation

Clock Control Modes

Primary Reference (timecode) Mode

No setting of time is required when input timecode is provided to the
ADC Series clock. Once valid timecode is detected, either SMPTE or
EBU, the clock will begin to self-set. The self-setting procedure moves
the hands at a rapid rate in either the clockwise or counter-clockwise
direction until the correct position is obtained. If the hands and the
correct time are the maximum distance apart (6 hours), the self-setting
process may require up to 15 minutes to complete.

Once the clock hands match the correct time, as indicated by the input
timecode, the error LED on the clock face will extinguish to indicate
that the clock is synchronized with the timecode.

The clock may require up to 2 additional minutes of normal operation
(following self-set) for the second hand to completely re-synchronize.
This is due to accumulated gear slippage during counter-clockwise
movements.

If there is a failure of the input timecode, the clock will switch to the
Secondary Reference as selected by DIP switch SW4 on the rear panel.
Either the clock’s own internal crystal or the power line frequency may
be selected as the secondary reference. Both will provide the clock with
a timebase during the absence of input timecode. (Note that either a 50
Hz or 60 Hz power line frequency is suitable for the timebase, since the
clock automatically selects the correct frequency available.)

To signal the failure of the input timecode, the error LED on the clock
face will flash at a rate of twice per second. When correct timecode is
re-established, the clock will again self-set to the new time, and the
error LED will extinguish.

Similarly, if there is an error in the input timecode, the clock will
automatically switch to the secondary reference, and the error LED will
flash.

Note

Impulse input is not currently recognized by the ADC-5100 Series
clocks.

24 5000/5100 Series Digital Analog Clocks Installation and Operation Manual

Secondary Reference Mode

The ADC-5100 Series clocks will run as standard wall clocks when no
input timecode is provided. Rear panel DIP switch SW4 selects the
timebase to be used, either the clock’s internal crystal, or the power line
frequency (50/60Hz).

Chapter 2: ADC-5100 Series Analog Digital Clocks

Auxiliary Offset

Rear panel DIP switch SW2 should be switched to the

SECONDARY

position when the clock is used in this mode. When in

RUN ON

this position, the error LED on the clock face will extinguish. Note that
the clock will still function without selecting

RUN ON SECONDARY.

However, the error LED will flash at the rate of twice per second to
indicate the absence of input timecode.

When operating in this mode, the time must be set manually using the
rear panel set switches,

MANUAL SET, CW, and CCW. Once set,

however, the correct time is maintained even in the event of a power
failure. Upon the return of external power, the clock will automatically
self-set to the correct time. The internal battery-backed timekeeping
function will maintain time for up to two years in the absence of
external power.

DIP switch SW3 allows access to a user-programmed auxiliary offset
from the input timecode’s user bits. The timecode source, however,
must have the ability to generate the correct information in the user bits.

The MTG-3901, CSD-3901/3902, and CSD-5300 Clock System
Drivers are real time timecode sources 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.

5000/5100 Series Digital Analog Clocks Installation and Operation Manual 25

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 SW3 on the ADC-5100 Series clock is in the

OFFSET

position, the auxiliary offset found in the input timecode’s

USE

user bits is added to the input timecode. The clock hands then display
the total. If no input timecode is available, then DIP switch SW3 has no
effect. If the user bits are incorrectly programmed, then the offset is
disregarded.

Chapter 2: ADC-5100 Series Analog Digital Clocks

Local offsets (hand position offsets) are still in effect while using the
auxiliary offset. The hand positioning local offsets are totally
transparent to the input timecode’s user bit offset.

If input timecode is removed while
will retain the time with the offset added, not the original time.

Timecode Generator Mode (Master Clock)

The ADC Series Clocks can also function as real time timecode
generators, essentially operating as master clocks. In this mode, the
clock will be accurate to within +
MTG-3901, CSD-3901/3902, and CSD-5300 master clocks are
accurate to within +

To configure the ADC as a timecode generator, an internal connector
must be transposed so that the rear panel speaker-type connectors
become the timecode output terminals.

To do this, remove the 10 screws along the outside edge of the clock.
Carefully lift the rear panel from the chassis taking care not to disturb
the cables connected to the motor assembly. (If the cables become
disconnected, the time shown on the hands may become offset from the
real time, in which case, see “Clock Setting” on page 26.)

Follow the two wires from the speaker-type terminals to their connector
on the PC board. The connector, attached at point P1, must be removed
and reversed. Normally, the wires on the connector are located near the
corner of the board at pin 1. Reversing this will relocate the wires on the
connector to pin 10. When completed, return the rear panel chassis and
re-fasten the 10 screws.

USE OFFSET is selected, the clock

4 seconds per month. (The

1 second per year.)

After completing this process, the rear speaker-type connectors will
output real time timecode when DIP switch SW4 is set to the

INTERNAL position.

To set the time, see “Clock Setting”.

Clock Setting

When shipped from the factory, the hands are set to 12:00. The clock’s
internal microprocessor has been re-set to memorize this hand position,
and the internal battery has been electronically disabled to preserve
battery life during storage and shipping.

26 5000/5100 Series Digital Analog Clocks Installation and Operation Manual

Manual Setting

Chapter 2: ADC-5100 Series Analog Digital Clocks

When first powered up, the clock will start from 12:00:00. Or, if the
external timecode is present, the clock will automatically reset to the
correct time. This may take up to 15 minutes.

The battery is enabled when power is first applied. Henceforth, the
clock will continue to retain time information for the lifetime of the
battery, even if the power is disconnected.

The ADC Series clocks may be manually set using the three
push-button switches located on the rear panel. These push-buttons,
labelled

MANUAL SET, CW, and CCW may be used to reposition the

hands of the clock for any of the following reasons:

• The clock will be used as a Stand Alone Clock, locked to its own

internal crystal or AC line frequency. In this case the hands must be
initially set to the correct time.

• The clock will be used as a master timecode generating clock.

• The clock hands must be offset for a different time zone.

• The offset must be removed. (For example, an offset of hours,

minutes, or seconds may have been inadvertently applied if the rear
buttons were actuated without following the correct procedure. In
this case, the hands and the internal microprocessor must both be
set to the same time. The clock will then display the correct time
when timecode is applied).

•

Local Time Offsets

The clock hands may be electronically repositioned to provide a local
offset from the input timecode. This is particularly useful for displaying
multiple time zones from the same timecode source. There are a number
of methods to achieve this and the simplest is described below.

28 5000/5100 Series Digital Analog Clocks Installation and Operation Manual

Chapter 2: ADC-5100 Series Analog Digital Clocks

This method assumes that the local time reference is 12:00:00. The
hands are manually set to the required offset time (according to
Table 2-13 on page 29) and the microprocessor is then reset. This tells
the microprocessor that the hands are at the 12:00 position, whereas in
fact they are set to the offset time. When timecode is applied, the clock
will set itself to the correct offset time. To set an offset, follow these
steps:

1. Disconnect the timecode input.

2. Enter the Manual Set Mode by pressing and holding the

SET

button until the hands come to a complete stop and the error

MANUAL

LED at the bottom of the clock face is illuminated.

3. Set the hands to the offset time using the

CW and CCW buttons as

described in “Repositioning the Hands” on page 28. (For example,
to apply a + 4 hour offset, set the hands to 4:00. If the hands are a
long way off, the process may take up to 15 minutes. A short cut
method is described in “Hands are Offset” on page 32.)

4. Once the hands are positioned at the appropriate time, press and

hold the
still holding the

MANUAL SET button until the error LED flashes. While

MANUAL SET button, press and hold the CCW

button to reset the microprocessor. Once the LED extinguishes,
release the

CCW button and then the MANUAL SET button.

5. Re-connect the timecode. The hands should move to the correct

offset time.

Troubleshooting

Hands are Offset

Sometimes the hands are offset by any number of hours, minutes, or
seconds. This generally occurs when the microprocessor loses track of
where the clock hands are positioned. This problem may occur if the
rear push buttons have been pressed in the wrong sequence.

The hands can be re-aligned (see t“Repositioning the Hands” on

page 28). This involves setting the hands to 12:00:00, which may take

up to 15 minutes. A short cut method is provided below.

Note

You cannot use the short cut method for the
24-hour model ADC-5124.

In the shortcut method, the hands are re-positioned to the top of the
closest hour and then the microprocessor is advised of the new hand
position. To re-calibrate the hands using this method follow these steps:

1. Disconnect the timecode. The front LED will flash twice per
second.

2. Press and hold the

MANUAL SET button until the LED stays

illuminated.

3. Using the

CW and/or CCW buttons (as described in the section

“Repositioning the Hands” on page 28), position the hands to the

top of the nearest hour.

4. Press and hold

5. While holding

MANUAL SET. The error LED will start to flash.

MANUAL SET, press and hold the CCW button until

the error LED extinguishes.

6. While continuing to hold the
momentarily press the

CW button once for every hour indicated on

MANUAL SET and CCW buttons,

the hour hand. For example, if the hands are set to 7:00, press the

CW button seven times. The LED will flash once every time the
CW button is pressed. Doing this will tell the microprocessor what

time the hands are showing. To apply offset times, add or subtract
the number of hours offset to the number of times the
pressed. For example, for -3 hours offset, press the

CW button is

CW button 4

times (7 - 3). In case of difficulties, please see t“Local Time

Offsets” on page 28.
