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).
BNC 7 Output Jumpers
JP4 and JP6 configure the function of BNC 7 for composite or reclocked SDI output. Use figure 2,
the card labeling, and the following discussion to select the output for BNC 7.
Select one of the following options on both
JP4
and
JP6
as follows:
•
D — allows a reclocked copy of the input SDI signal to pass through BNC 7.
•
A — allows an analog composite signal to pass through BNC 7 (default setting).
Fault Report (SMPTE 269M) Jumper
Select SMPTE 269M Fault Reporting, EN ABLED or DIS ABLED, 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-7 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-7 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-7 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.
