A Word of Thanks
Congratulations on choosing the openGearTM ADC-142 Analog to Digital Converter with Audio
Embedding and Frame Sync. The ADC-142 is part of a full line of modular conversion gear for
broadcast TV environments. The Sierra Video Systems openGearTM line includes video decoders and
encoders, audio embedders and de-embedders, distribution amplifiers, format converters, and much
more. Sierra openGearTM modular conversion gear will meet your signal conversion needs now and
well into the future.
Should you have questions pertaining to the installation or operation of your ADC-142, please contact
us at the numbers listed on the back cover of this manual. We are happy to help with any questions
regarding this or any other openGearTM card.
Overview
The ADC-142 is a high quality format converter that also includes a full 16 channel audio embedder, a
12-bit analog to digital video converter, a 8 channel 24-bit balanced analog to digital audio converter,
and a full video frame synchronizer.
The ADC-142 has a full featured, high quality, 12-bit analog to 10-bit serial digital converter. The dual
rate HD/SD analog video input can accept all common analog video formats and will autodetect
between HD and SD.
The embedder functions like an audio router internal to the card. On the input side of the router are the
up to 16 channels (8 pairs) of discrete AES input, up to 8 channels of differential analog audio input.
On the output side are the up to 16 channels of embedded AES audio, and the up to 16 channels (8
pairs) of discrete AES output. The router acts as a full audio cross point: each of the 32 output channels
(16 embedded AES, 16 discrete AES) can receive signal from any one of the 29 (16 discrete AES, 8
Analog, 4 tone generator, 1 silence) input channels. Each output also allows gain adjustment and
optional polarity inversion.
Page 6 of 29 ADC-142 Owner’s Manual •••• (V 2.1)
Audio rates are always 48kHz nominally but discrete AES inputs pass through sample rate converters
to align them with the output timing. The sample rate converters can be disabled if necessary. Output
AES is always precisely locked in time with the output video. Analog audio is differential input and
sampled at 48 kHz with 0 dbFS digital equivalent to a +24 dBu analog.
There are several advanced features available for the AES inputs. These include input sample rate
converter bypass, low-latency embedding of AES inputs, and AES input to output pass through. These
are covered in more detail in the section: AES Audio Input Advanced Features.
The product also provides full color processing control of the output video, with separate controls for
Luma Gain, Luma Lift, Chroma Saturation and Color Phase.
All card configuration is done with a simple front panel menu. There is a four character text display to
view and control parameters, and a toggle switch and two buttons to navigate the menu. Card
configuration can also be done over Dashboard remote control software.
The input and outputs of the ADC-142 are the following:
Input:
One 3-BNC dual-rate HD/SD analog video input
4 dedicated AES input connections (AES input 5-6)
8 differential analog audio inputs
Switchable Input/Outputs:
4 AES connections, switchable between input and output (AES input/output 1-4)
Outputs:
Two dual-rate HD/SD-SDI video outputs
8 dedicated AES output connections. (AES output 1-8)

Notes:
1. All rates displayed as frame rates, interlaced (“i”) field rates are two times the number shown.
Analog Audio
The ADC-142 supports 8 channels differential analog audio. The analog audio is converted in such a
way as to make +24 dBu (analog) equivalent to 0 dBFS (digital).
Discrete AES Audio Input
The ADC-142 can accept 16 channels (8 pairs) of discrete AES audio on 75 ohm BNC connections.
The AES must have a nominal rate of approximately 48 kHz. Sample rate conversion is employed to
account for minor clock rate differences in the input AES stream and the input video stream. However,
the card does not support AES input at 32 kHz, 44.1 kHz, 96 kHz or 192 kHz rates.
Page 8 of 29 ADC-142 Owner’s Manual •••• (V 2.1)
Discrete AES Audio Output
The ADC-142 can emit 16 channels (8 pairs) of discrete AES audio on 75 ohm BNC connections. The
AES clock rate will be precisely locked to the output video rate.
AES Audio Input Advanced Features
AES Sample Rate Converter Bypass
The card’s AES inputs have built in sample rate converters that are enabled by default. This allows the
card to interface with asynchronous AES sources (sources who’s AES timing does not match the video
reference timing.). They can be bypassed with a control in Dashboard or the front panel. This is a
necessity when trying to embed non-PCM AES audio such a Dolby E or Dolby Digital audio streams.
This control is off by default.
Zero-Delay Audio Embedding
Sometimes it is desirable to embed AES with minimum latency. For example, if you want to embed
Dolby E audio into video with no latency, and delay the video by one frame to account for Dolby E
encoding delay. By turning this control on for a given AES pair, the pair will be directly embedded into
it’s corresponding group, bypassing the normal frame sync audio delay. (AES Pair 1 into Embedded
Group 1, ch1 & ch2, AES pair 2 into Embedded Group 2, ch3 & ch4). This control overrides the
standard audio routing system: if AES Pair 1 is selected, then the controls to route into Embedded
group 1, ch1 & ch2 don’t apply. There is no gain or polarity control available when this option is
selected. This control is off by default
Low latency AES Passthrough
This control is similar to zero delay audio embedding. If selected for input pair X it causes AES output
pair X to act as a bit for bit copy of AES input pair X. This over rides the normal audio routing and
delay. No gain and polarity adjustments are possible. This control is off by default.

Card Control and Status
Card Status
The card indicates the status of the input signal with the four blue LEDs labeled with the different
supported formats (1080, 720, 625, 525). When the card has locked to a particular input format, that
LED will be illuminated. When the card has not locked to a particular video format, the card will
search all possible formats, and the lights will cycle rapidly.
Menu Navigation
The card can be configured from a menu system built in to the front card edge. This provides an
intuitive and easy to use method for exploring and using the features of the card.
The menu is navigated by using the toggle switch and the two push buttons. The lower button is the
“Enter” button to enter a submenu, and the upper button is the “Exit” button to exit a submenu. Moving
the toggle switch up or down moves up or down in menu choices, and pressing the buttons moves in or
out of sub menus.
The menu LEDs will illuminate from top to bottom to indicate increasing depth in the menu.

Frame Sync Enable
Enables the frame sync. If disabled the output video timing matches the input video timing.
Horizontal Offset
Allows the user to specify an additional horizontal offset between the output video and the frame sync
reference in sample clock periods. These are sample clocks in the reference format, not the output
video format. For example, if using SD black burst to time 720p59.94 video each sample clock is 37ns,
not 13.5ns.
Vertical Offset
Allows the user to specify an additional vertical offset between the output video and the frame sync
reference in lines. These are lines in the reference format, not the output video format.
Frame Latency
Specifies the smallest amount of latency allowed by the frame sync. This latency measurement is in
frames of the output video. The frame sync will not output a frame unless the specified number of
frames are captured in the buffer. Minimum latency is three lines and zero frames in all video modes.
The maximum latency is format dependent. The operational latency of the frame sync is always
between the specified minimum latency and minimum latency plus one frame (not one field).
ADC-142 Owner’s Manual •••• (V 2.1) Page 15 of 29
Audio Delay
Specifies the amount of additional audio delay after matching video delay. When the change is under
one and a half frames, the change in audio delay will be applied without interrupting audio. When
changing audio delay more than a frame and a half at a time, there will be a slight audio glitch.
Video Delay
Reports the current amount of video delay in ms.
Reset Frame Sync
Resets the frame sync, clearing any buffered audio and video. You must reset the framesync after
manipulating the horizontal and vertical offset in order re-establish correct audio and video co-timing.

Output Source
Because the cards audio system functions like a router, each output can be sourced from any input
channel. This parameter lets you choose from the many different sources. Here is an explanation of the
different source names:
Source Name Description
AeXX Discrete AES channel XX (1 through 16)
AnX Analog Audio channel X (1 through 8)
TgX Test Generator channel X (1 through 4)
Page 16 of 29 ADC-142 Owner’s Manual •••• (V 2.1)
Output Gain
The gain of each output is adjustable from +30 dB to –100 dB in 0.1 dB steps. After –100 dB gain is
set to –Inf, which means that output is present, but muted.
Output Polarity
If set to “Norm” output polarity is the same as input polarity, if set to “Inv” the output polarity is
inverted. This can be used to correct polarity errors in the input signals fed to the card.
Tone Frequency
This sets the frequency of the test tone for each of the four tone generators. Each of the four tone
generators TG1 – TG4 can be set to a different frequency, and are available as audio sources for the
embedded or AES audio outputs. The tones can range from 50Hz to 16kHz.

Service Information
In This Chapter
This chapter includes the following sections:
• Troubleshooting Checklist
• Warranty and Repair Policy
Troubleshooting Checklist
Routine maintenance to this openGearTM product is not required. In the event of problems with your
card, the following basic troubleshooting checklist may help identify the source of the problem. If the
module still does not appear to be working properly after checking all possible causes, please contact
your openGearTM products distributor, or the Technical Support department at the numbers listed under
the “Contact Us” section at the end of this manual.
1. Visual Review Performing a quick visual check may reveal many problems, such
as connectors not properly seated or loose cables. Check the module, the frame, and
any associated peripheral equipment for signs of trouble.
2. Power Check Check the power indicator LED on the distribution frame front
panel for the presence of power. If the power LED is not illuminated, verify that the
power cable is connected to a power source and that power is available at the power
main. Confirm that the power supplies are fully seated in their slots. If the power
LED is still not illuminated, replace the power supply with one that is verified to
work.
3. Reseat the Card in the Frame Eject the card and reinsert it in the frame.
4. Check Control Settings Refer to the Installation and Operation sections of the
manual and verify all user-adjustable component settings.
5. Input Signal Status Verify that source equipment is operating correctly and that a
valid signal is being supplied.
6. Output Signal Path Verify that destination equipment is operating correctly and
receiving a valid signal.
7. Module Exchange Exchanging a suspect module with a module that is known to
be working correctly is an efficient method for localizing problems to individual
modules.
8. Red Error Light – If the red error light is illuminated, verify that the frame sync is
set to the same reference that is being used on the back of the openGearTM frame
(REF1 LOOP or REF2 LOOP), and that the reference is properly terminated.
