CMA-8011A User Manual (Iss.05) Introduction •1-1

Overview
The CMA-8011A Component Monitoring Amplifier provides a convenient and cost effective dual-
purpose solution for signal distribution and picture monitoring requirements in serial digital
component (4:2:2) systems. The complete unit occupies only a single card slot in a standard RossGear
8000 series digital products rack frame. Ten modules may be mounted in the 2RU frame, with four
modules in a 1RU frame.
The CMA-8011A addresses high quality imaging requirements by converting the 8 MsB's of an SDI
signal to analog composite video. It uses a 10-bit DAC with a 10MHz bandwidth, thereby achieving
low artifact video output.
The CMA-8011A provides four composite analog monitoring outputs and can work in either NTSC or
PAL environments. In addition to converting the digital signal, the CMA-8011A also outputs four
reclocked SDI streams. The SDI input has an exceptionally good cable equalizer that will give error-
free performance with up to 305 meters (1000 ft.) of Belden 8281 cable.
Several user-selectable settings are available to place the CMA-8011A into the proper operating mode.
Some of these modes are; setting the monitoring outputs to monochrome, output a 75% color bar
pattern and blanking the vertical interval.
Of special interest on the CMA-8011A is the inclusion of an adjustable analog cable equalizer for the
analog output signal. This adjustment can be set to equalize up to 90 meters (300 ft.) of Belden 8281
cable, thus ensuring that the monitoring signal is delivered to the destination without chroma loss.
The CMA-8011A has card-edge LED indicators to confirm adequate serial digital input signal
strength and to indicate monitoring errors.

Output Mute Jumper
Select one of the following options on JP1 as follows, to enable or disable the Output Mute option:
• Low Sig — output will be muted if the input signal degrades to the point that the
input EQ can no longer guarantee error-free performance. When the red ERROR
LED is on, the outputs will be muted.
• Off — the card will work to the limits of the input stage (default setting).
Fault Report (SMPTE 269M) Jumper
Select SMPTE 269M Fault Reporting, ENABLED or DISABLED, via JP5. The default is EN.
See Chapter 3, “SMPTE 269M Fault Reporting” for complete details.
Equalization Setting
Use figure 2, the card labeling, and the following discussion to adjust the CMA-8011A equalization
setting.
Set the analog output EQUALIZATION adjustment (RV2) for the cable length used between the
amplifier and analog destination equipment. Plug the board into the frame and apply power.
The equalization control is calibrated for Belden 8281 cable. For other types of cable, put the board
on the extender, apply a D1 color bar signal and, using a scope, set the EQUALIZATION adjustment
for correct chroma level at the destination.
Board Installation
Use the following steps to install the CMA-8011A cards in a RossGear DFR-8104A or DFR-8110A
digital frame:
1. Refer to the User Manual of the RossGear 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 CMA-8011A 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.
BNC Labels
Affix the supplied BNC label, as per the included instructions, to the BNC area on the rear of the rack
frame.

LED Color Status Description
OK Green
The input signal is suitable for achieving error-free
performance. It is within the capability of the cable
equalizer and reclocking circuit to restore the signal.
ERROR Red
This indicates that the input signal is too low or absent.
In some circumstances, the signal may still be restored
correctly but the circuits will be working close to the
limit of their capability and reliability cannot be assured.
Red This indicator identifies a problem either with the input
signal or with the analog conversion section of the card.
Red long flash

There is no input signal, or the SDI equalizer is working
at, or beyond, its maximum capability.

SMPTE 269M Fault Reporting
In This Chapter
This chapter contains the following sections:
• Overview
• Jumper Setup
• Frame Connections
• Details
Overview
The SMPTE 269M Fault Reporting system, also known as a SMPTE “alarm”, provides indication if
one or more frame modules encounter a fault or an abnormal condition. The CMA-8011A module
provides a jumper to enable SMPTE-269M fault reporting. The card connects by means of an internal
interface circuit to an auxiliary telco connector on RossGear 8000 series frames. When the frame
connection is interfaced with a customer-designed system of LEDs or audible alarms, faults can be
traced to a specific frame when a card fault occurs within that frame.
The following diagram illustrates a general arrangement for SMPTE 269M alarm reporting:
Figure 5. SMPTE 269M Alarm Reporting: Internal interface and typical connections
CMA-8011A User Manual (Iss. 05) SMPTE 269M Fault Reporting •3-1

Jumper Setup
If fault reporting for the CMA-8011A is desired, use jumper JP5 - FAULT REPORT (269M) to set
up the card.
1. To access the jumper, remove the card from the frame by pressing down the white
card ejector tab and pulling the card from the frame slot.
2. Observing all static discharge and handling precautions, place the card with the
component side facing up on a clean flat surface.
3. To enable SMPTE fault reporting, set jumper JP5 to EN position.
4. To disable SMPTE fault reporting, set jumper JP5 to DIS position.

Frame Connections

Details
The fault report contacts are closed when the card detects an internal failure or a power loss condition.
The fault report will pulse closed for 1 to 2 ms every 16ms when the input signal is low, missing, or
invalid.
Some internal failures are:
• Failure of the card to initialize
• Failure in the fault reporting circuitry
• Failure to detect a valid input signal to the card
For additional information on alarm system design, refer to the SMPTE document ANSI/SMPTE
269M - 1999.
