A Word of Thanks
Congratulations on choosing the Ross Video ADC-8032A Analog Composite to SDI Decoder. You
have purchased a powerful, versatile, and advanced decoder. The ADC-8032A is part of a full line of
Digital Conversion Products within the RossGear Terminal Equipment family of products, backed by
Ross Video’s experience in engineering and design expertise since 1974.
You will be pleased at how easily your new ADC-8032A fits into your overall working environment.
Equally pleasing is the product quality, reliability and functionality. Thank-you for joining the group
of worldwide satisfied Ross Video customers!
Should you have a question pertaining to the installation operation of your ADC-8032A, please
contact us at the numbers listed in this publication. Our technical support staff is always available for
consultation, training, or service.
Overview
The ADC-8032A Analog Composite to SDI Decoder is a 10-bit broadcast quality decoder with a 12bit analog to digital converter. It is specifically designed for broadcast or production situations in
which an analog PAL, PAL-M, PAL-N, or NTSC composite signal must be converted to a component
SDI signal. Four SDI outputs are provided. The ADC-8032A fits into the Ross 8000 series digital
frames, with four cards in the DFR-8104A (1RU), and up to ten cards in the DFR-8110A (2RU).
Please refer to the frame User Manual for specific ventilation and cooling instructions to maintain
optimum operating conditions. This card also fits into Leitch* FR-6800 series frames to provide you
with greater installation versatility. The ADC-8032A is available in two different models:
* Leitch is a trademark of Leitch Technology Corporation
ADC-8032A User Manual (Iss. 04) Introduction • 1-1
• ADC-8032A - The base model decoder includes Proc Amp, Line Delay, and Line
Synchronizer timing modes.
• ADC-8032A-S - The “S” model includes a Frame Synchronizer, along with all the
features available on the ADC-8032A
The ADC-8032A-S version comes with a fully functional frame synchronizer, capable of
synchronizing incoming video to house reference. Various timing modes are available to
accommodate most situations. New techniques in frame synchronization contribute to the board’s low
power requirements and compact design. The complete circuit for the ADC-8032A, including a 12-bit
A-D converter, decoder, frame (or line) synchronizer, serializer, TTL tracking delay pulse, and
microprocessor is contained on a single DA-sized card. Additional daughter cards are not required.
A rich set of features is instantly accessible using simple card-edge switches and controls in
conjunction with a concise Heads-Up Display. The ADC-8032A’s 10-bit decoding process provides
excellent performance with all types of picture sources. In order to achieve the highest level of
precision, all signal processing and decoding is performed entirely in the digital domain. The decoder
uses a very sophisticated 5-line comb filter with advanced adaptive control algorithms.
To make configuration simple and easy, the ADC-8032A offers a Heads-Up Display mode for most
board-level adjustments. This display is especially convenient during setup, and for programming
several ADC-8032A cards with identical configurations. With the display enabled, the parameter
currently being adjusted has its value super-imposed over all board outputs. As an alternative to the
Heads-up Display, the board’s Comlink Terminal Display allows you to view all settings
simultaneously on any PC running VT-100 terminal emulation. The only requirement is a connection
between the PC’s serial port and the ADC-8032A’s Comlink connector. This feature is especially
convenient for making adjustments while the card’s output is on air.

Caution
Whenever handling the ADC-8032A and other related equipment, please observe all static discharge
precautions as described in the following note:
Static discharge can cause serious damage to sensitive
semiconductor devices. Avoid handling circuit boards in high
static environments such as carpeted areas, and when wearing
synthetic fiber clothing. Always exercise proper grounding
precautions when working on circuit boards and related
equipment.
Unpacking
Unpack each ADC-8032A you received from the shipping container, and check the contents against
the packing list to ensure that all items are included. If any items are missing or damaged, contact
your sales representative or Ross Video directly.

Jumper Setup
Use the following steps to set up ADC-8032A jumpers. These steps are performed before installing
the unit in the frame, but may be repeated as required. Refer to Figure 2 for card jumper locations.
Figure 2. ADC-8032A Jumper Locations
1. Using the figure above and the card silk-screening, set JP5 (Input Select) to select
the input video standard:
• Set jumper on pins 1-4 (Auto) to automatically select between
NTSC and PAL (default setting)
• Set jumper on pins 2-5 (PAL-M) for PAL-M decoding
• Set jumper on pins 3-6 (PAL-N) for PAL-N decoding
2. An analog composite reference is required for Line Sync and Frame Sync modes.
Using the figure above and the card silk-screening, set Jumper JP3 (Ext Ref) to
determine the location from which you want to obtain external reference.
• Set jumper on pins 1-2 (Frame) to obtain the reference from the frame’s
master reference (analog reference) connector (default setting)
• Set jumper on pins 2-3 (O/P8) to obtain the reference from connector 8 on
the back-plane
3. (Optional) Using the figure above and the card silk-screening, set Jumper JP4
(269M Fault Reporting) to enable or disable the card’s SMPTE alarm:
• Set jumper on pins 1-2 (EN) to enable SMPTE fault reporting (default
setting)
• Set jumper on pins 2-3 (DIS) to disable SMPTE fault reporting
(See Chapter 5, “SMPTE 269M Fault Reporting” for details on fault reporting.)

Board Installation
Use the following steps to install the ADC-8032A in a RossGear 8000 series digital distribution frame:
1. Refer to the User Manual of the RossGear 8000 series frame, to ensure that the
frame is properly installed according to instructions. If this module is to be installed
in any compatible frame other than a Ross Video product, refer to the frame
manufacturer’s manual for specific instructions.
2. Please note that heat and power distribution requirements within a frame may dictate
specific slot placement of cards. Cards with many heat-producing components
should be arranged to avoid areas of excess heat build-up, particularly in frames
using convectional cooling.
3. After selecting the desired frame installation slot, hold the ADC-8032A card by the
edges and carefully align the card edges with the slots in the frame. Then fully insert
the card into the frame until the rear connection plug is properly seated.

• If you wish to obtain the reference directly from the card’s back plane, connect
a composite analog color black reference to BNC 8. Be sure that pins 2-3
(O/P8) are shorted on Jumper JP3. Please refer to the previous section entitled,
“Jumper Setup”.
Note
BNC 8 is terminated at 75-ohms on the card.
• If you wish to reference the card from the frame’s Master Reference connector,
ensure that a composite analog color black reference signal is connected to the
REF BNC on the frame (see Figure 6 in chapter 5). Be sure that Jumper JP3 is
set to pins 1-2 (Frame).

SW1 – Function Select Switch
The SW1 Function Select switch is a 16-position rotary switch used to select functions such as
decoder channel, video standard, and video setup menu items. The SW1 switch works in
conjunction with the SW2 toggle switch; first, the function category is selected with SW1, and
then the SW2 toggle switch is used to select modes or configuration settings within that function
selection. See Chapter 4, “Using Banks” for complete details.
SW2 – Mode Select Switch
The SW2 Mode Select switch is used to enable, disable, and select specific ADC-8032A
functional modes, or configurations, within the operational function menu (selected first with the
SW1 Function Select switch). The Mode Select switch is a 3-position momentary toggle switch
with an automatic spring-return to the center (null or unity) position.
Two methods of toggling SW2 are used to select basic and advanced level menu items.
• Single toggle to select single options
• Hold toggle to scroll through multiple values or options
Toggling the switch for menu selection is made according to two basic menu design categories:
• menu selections utilizing a scrolling wrap-around style of selection (from last
menu item directly back to first menu item)
• menu selections utilizing a bi-directional upper and lower range limit
