transmission link paths and to provide alarm and status information to centralised monitoring facilities.
The following features are provided:
• Automatic operation.
• Selection of main / reserve / standby priority.
• Local / remote control of all functions.
• Remote and local status information.
• Audio fail override facility using IRT AG‐738 / AAD‐4130 audio detector.
The video signals of the main, reserve and standby paths are monitored, with an indication provided to show the
loss of the input signal. Any of the main, reserve or standby paths can be selected as the priority path and,
provided a signal is present, this selection will be the ON AIR source.
If the priority selected path should fail the unit will provide control signals to select another input. Where a failure
occurs on main, reserve and standby inputs then the system will select the local input. Once any input signal is
restored, the system will switch back from the local signal to an input signal, with the priority‐selected input
having precedence when more than one input signal is available.
The front panel indicators and controls provided are:
• Fail LED's on the main, reserve and standby paths.
• Indication of the priority source selected.
• Indication of the ON AIR source.
• Auto/manual enable indication.
• Push buttons for priority selection of sources in auto mode and direct selection of manual mode.

Revision 15
Operational Description
The CDC‐3062 Eurocard module has three video failure detectors; designated main, reserve and standby.
Full interfacing to IRT 3000 series Eurocard switchers is provided, in addition it also has four logic level outputs for
selecting one of four crosspoints on an IRT Eurocard series switcher. (Types VA‐710, AA‐720 and / or AA‐751 (obsolete))
The four crosspoints may be designated main, reserve, standby and local.
The controller may be operated in one of two modes; manual or auto.
Manual mode:
In manual mode, the four front panel switches provide direct selection of the four controlled crosspoints.
Switching between auto and manual modes may be made using the front panel pushbutton switch or by an opto‐
isolated remote interface. The action of this switch / remote input is a toggle action and it is therefore essential
that this switch be returned to the auto position once any servicing work requiring manual operation is completed.
A visual indication of manual mode is provided by the red LED immediately below the manual switch. A remote
tally of this mode is also provided so that the mode is known when operated by remote control.
Auto mode:
In auto mode, the four front panel switches are used to set the “priority” of the four crosspoints.
If main has the priority then:
If a valid signal is present on main then main is selected.
If main fails and a valid signal is present on reserve then reserve is selected.
If main and reserve both fail and a valid signal is present on standby then standby is selected.
If main, reserve and standby all fail then local is selected.
If reserve has the priority then:
If a valid signal is present on reserve then reserve is selected.
If reserve fails and a valid signal is present on main then main is selected.
If main and reserve both fail and a valid signal is present on standby then standby is selected.
If main, reserve and standby all fail then local is selected.
If standby has the priority then:
If a valid signal is present on standby then standby is selected.
If standby fails and a valid signal is present on main then main is selected.
If standby and main both fail and a valid signal is present on reserve then reserve is selected.
If main, reserve and standby all fail then local is selected.
If a failed signal is restored then selection takes place according to the above priorities.
A video failure is deemed to have occurred when the synchronising signals of a composite video signal fall in level
by more than 6 dB from standard.

Revision 15
Front panel controls & indicators:
Pushbuttons:
The front panel has four selector pushbuttons called main, reserve, standby and local.
In manual, these are used to select crosspoints 1, 2, 3 & 4 of the connected video switcher.
In auto
main sets main as the priority channel
reserve sets reserve as the priority channel.
standby sets standby as the priority channel.
Each switch has an LED indicator.
In manual mode, the LED’s act as tallies indicating the selected path.
In auto mode the LED’s act both as tallies and indicators of the currently selected priority by intermittently
flashing.
Pressing either the main, reserve or standby switches for a period longer than 2 seconds causes the selected
switch to act as the priority.
Auto / manual switch:
This switch selects auto mode under the direction of the priority controller and failure detectors or manual mode
for direct control regardless of failure status.
Note that the action of this switch is to toggle between the two modes and hence pressing the switch will change
from the current mode to the other.
In order to know which mode is current a warning LED and remote tally is provided to indicate manual mode when
selected.
Failure indicators:
An LED indicator is provided for the main, reserve and standby channels, which lights in the event of a failure being
detected on that channel.

Technical Description
See drawing 804084 sheets 1 ‐ 2.
Video inputs.
Each video input connects to a high impedance emitter follower buffer that allows a loop through connection to
be made if required. If the loop through is not connected, a 75 Ohm termination BNC connector should be fitted
to the loop through socket to ensure correct levels are present at the detector.
The detector circuit uses an Elantec EL4583C integrated circuit. Pin 2 is the "Set Detect Level" and determines the
value of the minimum signal that will trigger the "No Signal Detect Output" on pin 10.
The relationship is VpMIN = 0.75 * RV 1 / 680 K, where VpMIN is the minimum detected sync pulse amplitude
applied to pin 4. The detection operates on both horizontal and vertical sync.
The delay from loss of input signal to "No Signal Detect Output" is typically 600 s. This is too fast for this
application as the loss of an individual horizontal sync pulse is of no consequence.
Furthermore, if the sync pulse level falls to near the threshold any noise on the signal will cause repetitive
triggering. As the switchers being controlled normally switch only during the vertical interval, a delay of up to one
field will not effect switching performance.
To overcome these problems the "No Signal Detect Output" is passed through a filter circuit that both increases
the time constant and introduces hysteresis to provide differing "ON" and "OFF" timing.
Response time is set by the time constant for charging / discharging C 6, 14, 22. The diode isolates the charging
and discharging paths.
The resistor values shown are found to be good for most applications, but may be changed if required.

The output of the hysteresis circuit is connected to an LM311 comparator with open collector output. See Audio
only operation for a detailed description of this part of the circuit.
Audio override inputs.
The name of these inputs is not intended to imply that they be used for audio signals, but rather that they are
normally used for alarm outputs from audio fail detectors.
They may in fact be used with any type of external alarm signal, for example those available from digital decoders
or timebase correctors.
Due to the complexity of decision making in determining what constitutes an audio failure, this is left to a separate
module. See IRT's AG‐738 stereo failure detector manual.
The audio override inputs are via opto isolators and may be configured for various modes of input signal. See
Configuration for more details.
Logic processing.
The outputs of the three path alarm inputs, switch data and other inputs and outputs are processed and
controlled by U 12. This programmed logic controller contains firmware programming which provides the
necessary logic functions. It is only available from IRT and cannot be serviced in the field except by replacement
with an IRT supplied chip.
A full explanation of the programming is beyond the scope of this manual.

Tally & status outputs.
See also information under Installation ‐ Connections.
The tally and status outputs from the PLA logic chip are buffered by 75452 relay / lamp drivers with open collector
outputs. These provide ample current and voltage rating for normal applications. Links are provided to allow a
choice between a logical voltage output and a current sinking output.
The Reserve OK and Standby Tally are not provided with these links due to space limitations. These outputs
require an external pullup resistor if they are to provide voltage outputs.
Remote automatic/ manual operation input.
This input is opto‐isolated using the same technique as the Audio Override inputs. The action of this input is to
toggle between manual and automatic modes of operation. The opto‐isolator output is directly connected to the
front panel switch that provides the same function and so either will cause a change of mode. See Installation ‐
Connections for more information.
Switcher interface:
The connections from the PLA chip to an IRT 3000 series switcher are via connectors PL 4 & PL 5. For a full
description of this interface and switcher protocol, see the 3000 Series Switchers manual.
Relay Function:
(Applies to serial numbers later than 9912000 only. See circuit diagram 804084 Sheet 1 rev. 2+ and 804084 sheet
3)
A relay is mounted on the rear connector unit via PL3 for connecting to any of the alarm outputs via PL1 to provide
a relay closure alarm output. Connection is made by the user connecting pin PL3‐8A to the chosen relevant pin on
PL1.
Power supply:
The module may be powered by AC or DC, single or dual supplies. Resistors F 1 to F 4 provide fusing protection to
the power supply buss in the event of catastrophic failure of the module. If the module is subjected to continuous
high voltage supply input, these resistors might go high in value with a consequent loss in voltage delivered to the
regulator circuits and consequent loss of regulation.
Diode bridges D 1 to 4 and 5 to 8 function as full wave rectifiers for AC supplies and as reverse voltage connection
protection and isolation for DC supplies.
A standard 3 pin voltage regulator is used to provide the +12 Volt supply rail.
The +5 Volts required by the logic circuits are supplied from a DC/DC converter. This is connected across the
positive and negative unregulated supplies so that a balance is maintained in the current drawn from these two
sources. This would normally result in a higher than normal input voltage being applied to the converter. So the
combination of resistors R 55, R 56 and Zener diode ZD 1 are included to ensure that the converter is always
operated within its safe input margin.
Capacitors C 25, 36, 37 and 38 are located at key points in the circuit layout to provide local high frequency bypass
to the +5 Vdc supply.
Internal Adjustments
The following adjustable resistors are factory set and should not be adjusted unless a component has been
replaced. They are not 'operational' controls. Before adjusting any of these controls, allow time for the module to
reach temperature stability.
RV 1
RV 2
RV 3
Main video sync failure sensitivity.
Reserve video sync failure sensitivity.
Standby video sync failure sensitivity.
Correct setting for each of the above is as follows:
Apply a 1V video signal via a 75 Ohm attenuator box to the video input and set the corresponding control so that
the corresponding front panel FAIL LED is off with 6 dB attenuation and on with 7 dB attenuation.

Revision 15
Audio only operation:
The CDC‐3062 may be used without video for audio only applications or for use with general alarm signals using
the audio override inputs. This allows the complex logic of the CDC‐3062 to be applied to many situations where
analogue video is not present, but fail alarms are provided.
These include digital video, audio, data, FSK and ACS path switching.
The output of each video sync detector is fed to a comparator's inverting input. The non‐inverting input is
connected to a reference voltage formed by resistors R 28 & R 29. By removing R 29 the comparison is now made
to +5 Vdc. This will result in the output of the comparator always being high.
Note that this modification affects all three video inputs. Its main advantage is that it may be done simply by
snipping the lead at one end of the resistor and can easily be restored later if the required use changes.
If only one or two video inputs are to be disabled, the LM311 for those inputs should be removed.
The comparator used is an LM311, which has an open collector output.

The collector is normally pulled high to +5 Vdc by a 560 Ohm resistor (R 51, 52 or 53) and the control panel LED
failure indicator for that channel.
The open collector output allows a second connection to be made from the audio override input. This can also pull
the output line low and so the arrangement functions as an OR gate for the two alarm sources.

Installation
Operational Safety:
WARNING
Operation of electronic equipment involves the use of voltages and currents that
may be dangerous to human life. Note that under certain conditions dangerous
potentials may exist in some circuits when power controls are in the OFF position.
Maintenance personnel should observe all safety regulations.
Do not make any adjustments inside equipment with power ON unless proper
precautions are observed. All internal adjustments should only be made by suitably
qualified personnel. All operational adjustments are available externally without
the need for removing covers or use of extender cards.
Pre‐installation:
Handling:
This equipment may contain or be connected to static sensitive devices and proper static free handling
precautions should be observed.
Where individual circuit cards are stored, they should be placed in antistatic bags. Proper antistatic procedures
should be followed when inserting or removing cards from these bags.
Power:
AC mains supply:
Ensure that operating voltage of unit and local supply voltage match and that correct rating
fuse is installed for local supply.
DC supply:
Ensure that the correct polarity is observed and that DC supply voltage is maintained within
the operating range specified.
Earthing:
The earth path is dependent on the type of frame selected. In every case particular care should be taken to ensure
that the frame is connected to earth for safety reasons. See frame manual for details.
Signal earth: For safety reasons a connection is made between signal earth and chassis earth. No attempt should
be made to break this connection.

CDC‐3062 Instruction Book
Revision 15
Installation in frame or chassis:
See details in separate manual for selected frame type.
Connections:
Video:
The three video inputs provided are of a loop through type and must be terminated in 75 Ohms. Use either a
termination plug on the second BNC connector provided for each input or connect the second BNC connector to
another piece of equipment where the 75 Ohm termination is made.
In normal use, it is expected that the CDC‐3062 will be connected at the end of any chain of equipment whose
inputs are looped to provide the maximum sensing capability for a fault in these connections. In a PIE (Program
Input Equipment) configuration, the input to the program switcher controlled by the CDC‐3062 should loop
through the switcher input and then be connected to the corresponding CDC‐3062 input, where it is terminated
using a 75 Ohm BNC termination plug.
Audio override: (External alarm inputs)
The main, reserve and standby opto‐isolated audio override inputs provide for optional connection of an IRT
AG‐738 / AAD‐4130 audio failure detector.
Although termed audio override inputs these inputs may be used for the insertion of any external alarm by means
of a contact closure or a DC voltage. See Configuration.
Note that an audio signal should not be applied to these inputs. The term audio override is derived from the input
frequently being used in conjunction with an audio loss detector.
Care should be taken to ensure that the correct pins of connector PL 3 are connected according to the type of
alarm input.
Two connections are provided: One is normally tied to the internal +5 Vdc supply via a series resistor.
For normally open contacts, the ‐ve serves as a grounding contact to activate the failure indication.
For normally closed contacts the ‐ve should be connected to ground and the +5 V connected to the normally
closed contact to ground.
The internal supply connection may be disabled by a link (LK1, LK2, LK3) on the main module if required. However,
if this is done care should be taken to ensure that the correct supply polarity is observed and that a series resistor
is included to limit the current through the diode of the opto‐isolator. This should not exceed 20 mA.

Remote control inputs:
The remote control inputs offer the same facilities as the pushbuttons provided on the front panel of the
CDC‐3062.
Selection is made by making a momentary clean contact to the Gnd connection.
Special care should be taken with the connection to the Manual / Auto function. This function is a toggle action
and so any contact noise may be interpreted as more than one toggle command. If this input is to be used with
relay or switch contacts that may not always provide a clean connection then noise suppression capacitors should
be fitted to the contacts or a de‐bouncing circuit should be included.
Intelligent use of this input can only be made when tally information is returned to the remote location. Without
this information, the manual or automatic status cannot be assured.
The Manual / Auto input has been provided with an opto‐isolator to improve immunity to damage by transient
voltages. The remaining inputs have a degree of protection provided by series resistors between the control lines
and the logic circuit. Care should be taken however to ensure good earthing of remote equipment to eliminate
static discharge from passing down the control lines.

Program switcher connectors ‐(3000/4000 series Eurocard switchers):
Connection to the 3000/4000 series Eurocard switchers is made using 10 way ribbon cables observing the
direction of PL 5 (out) connects to PL 4 (in) on either switchers, control panels or the CDC‐3062.
The cables are wired on a pin for pin basis.
Before activating the switchers, control panels or the CDC‐3062 priority controller a check should be made of all
link settings on all switchers and panels to ensure that no conflicting settings are present.
In all cases, the number of switchers connected to one CDC‐3062 should not exceed 10.

Maintenance & Storage
Maintenance:
No regular maintenance is required.
Care however should be taken to ensure that all connectors are kept clean and free from contamination of any
kind. This is especially important in fibre optic equipment where cleanliness of optical connections is critical to
performance.
Storage:
If the equipment is not to be used for an extended period, it is recommended the whole unit be placed in a sealed
plastic bag to prevent dust contamination. In areas of high humidity a suitably sized bag of silica gel should be
included to deter corrosion.
Where individual circuit cards are stored, they should be placed in antistatic bags. Proper antistatic procedures
should be followed when inserting or removing cards from these bags.
Warranty & Service
Equipment is covered by a limited warranty period of three years from date of first delivery unless contrary
conditions apply under a particular contract of supply. For situations when “No Fault Found” for repairs, a
minimum charge of 1 hour’s labour, at IRT’s current labour charge rate, will apply, whether the equipment is
within the warranty period or not.
Equipment warranty is limited to faults attributable to defects in original design or manufacture. Warranty on
components shall be extended by IRT only to the extent obtainable from the component supplier.
Equipment return:
Before arranging service, ensure that the fault is in the unit to be serviced and not in associated equipment. If
possible, confirm this by substitution.
Before returning equipment contact should be made with IRT or your local agent to determine whether the
equipment can be serviced in the field or should be returned for repair.
The equipment should be properly packed for return observing antistatic procedures.
The following information should accompany the unit to be returned:
1.
2.
3.
4.
5.
6.
7.
A fault report should be included indicating the nature of the fault
The operating conditions under which the fault initially occurred.
Any additional information, which may be of assistance in fault location and remedy.
A contact name and telephone and fax numbers.
Details of payment method for items not covered by warranty.
Full return address.
For situations when “No Fault Found” for repairs, a minimum charge of 1 hour’s labour will apply,
whether the equipment is within the warranty period or not. Contact IRT for current hourly rate.
Please note that all freight charges are the responsibility of the customer.
The equipment should be returned to the agent who originally supplied the equipment or, where this is not
possible, to IRT direct as follows.
