Card Installation
This section provides a brief overview of the required Rear Modules and physical installation of the
9229-QS.
Note — The 9229-QS requires either the RM20-9229-C Rear Module and therefore is
not compatible with the 8310-BNC frames (frames with the pre-installed 100-BNC fixed
backplane).
Rear Modules
The procedure for installing the Rear Module in your openGear frame is the same regardless of the
frame or module used. However, a different module is required depending on the openGear frame you
are using. The Rear Module requires four slots in an HPF-9000 or 8321 series 20-slot frame.
RM20-9229-C Rear Module
The RM20-9229-C Rear Module provides a passive looping BNC on all four SDI inputs (Bkgd A, B,
C, and D). The SDI source signal should be connected to the BNC IN input and if required, the SDI
input signal may be propagated to one more downstream equipment using the associated BNC Loop
output. Refer to the section “Looping Rear Module RM20-9229-C” for BNC designations and for
additional cabling information.
ƒ If you are using the BNC Loop output(s), then the looping SDI cable must drive only one
piece of downstream equipment properly terminated with a 75 Ohm load at all time. If the
downstream equipment must be disconnected for servicing, it is recommended to first
disconnect the cable at the BNC Loop output of the RM20-9229-C Rear Module, otherwise
the looping cable without termination will cause signal reflection that will likely corrupt the
9229-QS SDI input signal.
ƒ If you are not using the looping output, then the BNC Loop should be left open without any
cable or standalone 75 Ohm termination attached to the BNC.
Installing the Rear Modules
If the Rear Module is already installed, skip this section.
Caution — It is not recommended to install this card in the Slots 1,2 combination in
an 8310 series frame, or in Slots 1,2, 3, 4 in the 8321 series frames. These
combinations provide the least air flow cooling in the frame and the card may overheat
if installed in this location.
Use the following procedure to install a Rear Module in 20-slot frame:
1. Refer to the frame product manual to ensure that the frame is properly installed according
to instructions.
2. (non-current) If you are installing the 9229-QS in an 8310 series frame, Cobalt Digital
Inc. recommends installing the Rear Module in one of the following combinations:
• Slots 3, 4 • Slots 7, 8
