1 imaging Quartet Housing Frames
1.1 Introduction
The
imaging
Quartet housing frame family support and provide power to a
maximum of 4
imaging
series modules in the same single rack unit housing frame.
A Quartet, Quartet-C or Quartet-M housing frame can accommodate any
combination of
imaging
series
video
modules; a Quartet-A-75, -A-110, -M-A-75 or
–M-A-110 housing frame can accommodate any combination of
imaging
audio
modules (combination of video and audio modules are not possible within the same
housing frame).
Two
imaging
Quartet housing frames can be interconnected via a rear panel
connector in order to provide power redundancy. In a redundant dual housing frame
installation, the power supply installed in the second frame is in back-up mode,
which maintains DC power levels in case of a local power supply failure. Refer to
section 3.2,
DC Power Redundancy
for more details.
Some Quartet housing frames are equipped with an RS-422 serial interface
providing remote configuration of
imaging
modules using Miranda's ICP-S
application. An RS-422 loop-through allows Quartet housing frames to be daisy
chained together and controlled by a host computer.
Audio modules can now be installed in Quartet housing frame supporting 75 ohm or
110 ohm I/O connections.
