A Word of Thanks
Congratulations on choosing the openGear® 9257 1x9 MADI Audio Distribution Amplifier. The 9257
is part of a full line of modular conversion gear for broadcast TV environments. The Cobalt Digital line
includes video decoders and encoders, audio embedders and de-embedders, distribution amplifiers,
format converters, and much more. Cobalt modular conversion gear will meet your signal conversion
and distribution needs now and well into the future.
Overview
Should you have questions pertaining to the installation or operation of your 9257, 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 of our cards.
The 9257 is a high quality 1x9 MADI Audio Distribution Amplifier The 9257 can reliably equalize up

ESD
Susceptibility
Unpacking
Unpack each card 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 Cobalt Digital directly.
Static discharge can cause serious damage to sensitive
semiconductor devices. Avoid ha ndling circuit boards in high
static environments such as carpeted areas, and when wearing
synthetic fiber clothing. Always exercise proper ground ing
precautions when working on circuit boards and related
equipment.
Page 8 9257 Owner’s Manual •••• (V 1.2)
Rear Module Installation
If you are installing the card into a slot with no rear module, you should have ordered and received a
Rear Module with your card. You will need to install it in your 20-slot frame before you can connect
cables.
Use the following steps to install the rear module in an 20-slot openGear
1. Refer to the frame Owner’s Manual, to ensure that the frame is properly installed
according to instructions.
2. On the rear of the frame, locate the card frame slot.
3. As shown in Figure 2, seat the bottom of the rear module in the seating slot at the
base of the frame’s back plane.
®

Figure 2. Rear Module Installation
4. Align the top hole of the rear module with the screw hole on the top edge of the
frame back plane.
5. Using a Phillips driver and the supplied screw, fasten the rear module to the frame
back plane. Do not over tighten.
This completes the procedure for installing the rear module in the frame.
9257 Owner’s Manual •••• (V 1.2) Page 9
Board Installation
Use the following steps to install the card in the 20-slot frame:
1. Refer to the Owner’s Manual of the 20-slot frame to ensure that the frame is properly
installed according to instructions.
Warning
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 convection cooling.
2. After selecting the desired frame installation slot, hold the 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 plugs are properly seated on the midplane and
rear modules.
This completes the procedure for installing the card in the 20-slot frame.

Cable Connections
This section provides instructions for connecting cables to the installed BNC rear modules on the 20slot frame backplane. Connect the input and output cables according to the following diagram. Split
rear module RM20-9257-A/S and RM20-9257-B/S allow two cards to be installed in adjacent slots.
B/S versions are available in DIN1.0/2/3 and HDBNC versions.

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.
