Introduction
Overview
The CMA-9011 SDI Component Monitoring Amplifier is a high quality
monitoring solution for SDI signals and part of a growing family of GearLite
self-contained, small brick-format modules.
The CMA-9011 addresses high quality imaging requirements by converting the
eight MSBs of an SDI Signal to Analog Composite Video (CVBS). A 10bit
DAC and special filtering techniques used in the design achieve a low-artifact
video output.
The front panel of the CMA-9011 chassis provides a power status LED for
visual reference. In addition, user-selectable settings are available to place the
CMA-9011 into the proper operating mode. Some of these modes are:
monochrome output, 75% color bar pattern, and vertical interval blanking.
The CMA-9011provides conversion of 525 and 625 SDI signals (SMPTE
259M). NTSC, PAL, and PAL-N standards are supported. Special measures
have been taken to ensure excellent return loss at both input and output. This
guarantees error-free performance with short cables.
The CMA-9011 is delivered with a universal power adaptor and line cord
suitable for the country of use. Various mounting options are included that allow
a wide range of installation choices. The CMA-9011 provides a
broadcast-quality SDI component monitoring solution in a small, stand-alone
package.

Installation
Static Discharge
Whenever handling the CMA-9011 and other related equipment, please observe
all static discharge precautions as described in the following note:
ESD Susceptibility — 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 CMA-9011 module you received from the shipping container and
check the contents to ensure that all items are included. If any items are missing
or damaged, contact your sales representative or Ross Video directly.
Mounting and Installation
The CMA-9011 can be mounted in any convenient location. However, to ensure
long life for this product, observe the following precautions and operating
requirements:
• Maintain an ambient temperature of 20°C to 40°C.
• Allow for air circulation around the chassis for convectional cooling.
Many different mounting positions are possible with the included mounting
hardware. Some installation options are permanent and require careful
consideration of the final positioning before installation. Please note that in
some mounting locations, the power adaptor must be affixed in a similar manner
as the chassis.
Other possible options include the use of adhesive magnetic sheets (not
included) affixed to the chassis and the power adaptor, for removable mounting
on metal cabinets etc.
Cable ties may be necessary in some applications to relieve strain on the
mounting hardware and the connectors.
Surface Mount Strips
The included VELCRO® brand surface mount strips allow the GearLite module
and power supply to be affixed to a permanent location during use and easily

removed for adjustments. Carefully consider the installation location before
proceeding; the adhesive is very aggressive and is not easily removed. The
adhesive will cure fully in 24 hours.
To install the Surface Mount Strips
1. Remove the Protective Backing Film from the adhesive on the
bottom of the two VELCRO® brand Surface Mount Strips.
2. Adhere the Surface Mount Strips to the bottom side of the chassis.
(Figure 2)
Figure 2 Surface Mount Installation Option
3. Remove the Protective Backing Film from the other side of the
VELCRO® brand Surface Mount Strips.
4. Press the chassis into position on the surface you want to mount it to.
Operating Tip — An additional VELCRO® brand Surface Mount
Strip is available to mount the power adapter.
Non-Slip Pads
Four non-slip adhesive pads have been supplied for desktop placements. Simply
remove the protective backing film from the adhesive and affix one non-slip pad
to each of the four corners on the bottom of the chassis.
Optional Mounting Accessories
Ross Video is committed to providing practical solutions for the needs of your
high-quality broadcast facility.

Flat Metal Plate
Use the flat metal plate for permanent mounting to a rack, a desk, or any other
location where bolts or screws can be applied. Be sure to position the module to
allow for operator adjustments, if required.
To install the Flat Metal Plate
1. Remove the 2screws from the bottom of the chassis.
2. Install the Flat Metal Plate onto the bottom of the chassis (Figure 3)
using the screws provided in the Mounting Kit. Do not use the screws
removed during Step 1.
Figure 3 Flat Metal Plate Installation Option
3. Install the chassis in the desired location using the Mounting Holes
on the Flat Metal Plate. Mounting screws are not provided by Ross
Video.
Angle Mounting Bracket
The Angle Mounting Bracket (Figure 4) allows a single GearLite module to be
installed in positions not possible with the flat metal plate. The bracket has a 90°
angle. Mounting screws are not provided by Ross Video.

Setup
Power Adapter and Supply
Connect the PS-9000 power adapter to the power supply connector. The
PS-9000 provides up to 2A of regulated +5V DC (5%). The DC power cord has
a locking connector that securely fastens into the power supply DC jack on the
CMA-9011. The CMA-9011 has a standard miniature power jack (center pin
positive).
If using an adapter other than the PS-9000, ensure that:
• the polarity is correct
• the voltage is +5V DC regulated to 5%
• sufficient current for the CMA-9011 is supplied
Caution — Use of improper adapters may damage the CMA-9011
and will void the warranty.
Installations outside of North America using line voltages of 200-240V require a
plug, certified for the country of use, to be installed on the supplied line cord.
Refer to the section “Important Regulatory and Safety Notices to Service
Personnel” at the front of this manual for details.
Cable Connections Overview
Connect the cables to the CMA-9011 according to the designations indicated on
the chassis label and Figure 5. The input is internally terminated at 75ohm. It is
not necessary to terminate unused outputs.
