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.

3 Installation

3.1 Rack Mount Installation

Quartet housing frames can be mounted in a standard 19" rack. The unit's front
panel is secured to the rack by installing the appropriate rack screws and nylon
washers. The front panel's paint finish may be damaged if nylon washers are not
used.

For proper ventilation, make sure that the front panel is installed and that the front
panel air vents and rear panel fan assembly are not blocked when power is on.

3.2 DC Power Redundancy

For those Quartet housing frames supporting DC power redundancy, the external
DC power supply connector may be used to get DC power from a second Quartet
housing frame or a Quartet-RPS frame. Interconnecting two Quartet frames
equipped with a DC connector is possible if the total power consumption for all
imaging modules installed into the two housing frames (for a maximum of 8) does
not surpass the current capacity of one power supply. To find out how much
current is required for the installed modules, refer to the Specifications section of
the module’s Guide to Installation and Operation. If the total consumption
surpasses the current capacity, a dedicated redundant power supply may be
installed in a Quartet-RPS frame which may hold up to three power suplies for
redundancy purpose. In both cases, during normal operation both power supplies
are active. If a power supply fails, the other power supply instantaneously provides
power to all modules. The FAIL LED will be switched on in the defective unit to
indicate its malfunction. In Quartet-RPS and Quartet frames listed in Table 1.1, a
dry contact may be wired to a remote monitoring system to indicate the power
supply failure. Refer to section 4 Power Supply for more details.

Figure 3.1 indicates how to interconnect two imaging Quartet housing frames. Refer
to figures 3.2 and 3.3 for cable construction.

3.4 RS-422 Serial Connection

y

For those Quartet housing frames supporting ICP-S, the rear panel includes 2
identical RS-422 ports which may be used interchangeably as the source or daisy
chain loop-through. This port directs communication between a series of housing
frames and a remote Windows NT workstation. A module's configuration may be
modified from this workstation without the need to push buttons or position jumpers.
Refer to the following steps for a single Quartet or multi-Quartet to remote Windows
NT workstation installation.

Single Quartet Installation:

1. Connect the RS-422 cable of Figure 3.7 between the PC/RS-422 converter and
one of the RS-422 ports situated on Quartet's rear panel.

2. Connect the Windows NT workstation and the PC/RS-422 converter with a
proper cable. Refer to the converter vendor documentation.

3. The final step in a single Quartet installation is the serial identification
assignment required for the housing frame. Refer to section 3.5 RS-422 Serial
ID Assignment.

Multi-Quartet Installation:

1. Connect the RS-422 cable of Figure 3.7 between the PC/RS-422 converter and
one of the RS-422 ports situated on the first housing frame in the daisy chain.

2. Connect the Windows NT workstation and the PC/RS-422 converter with a
proper cable. Refer to the converter vendor documentation.

3. A maximum of 16 Quartets, a maximum of 16 Symphonies, and a maximum of
16 Solos can be daisy chained together. Therefore, interconnect the housing
frames as shown in Figure 3.4 using appropriate cables (refer to section 3.6).
The final housing frame requires the supplied termination.

4. The final step in a multi-housing frame installation is the serial identification
assignment required for each individual housing frame. Refer to section 3.5
RS-422 Serial ID Assignment.

3.5 RS-422 Serial ID Assignment

In a multi-housing frame installation, each frame must be recognized by the
workstation. The only way to accomplish this is to assign an identification code to
each member of the daisy chain. This is similar to assigning different addresses to
buildings on a street. Follow these steps in order to identify each housing frame in
the daisy chain.

Assigning the RS-422 Serial ID on Quartet-C

1. Locate the ID rotary switch on Quartet-C's rear panel. Refer to Figure 3.5.

2. Using a small flat-edge screwdriver, identify each housing frame by setting a
unique address to each. The available addresses are 0, 1, 2, 3, 4, 5, 6, 7, 8, 9,
A, B, C, D, E, and F producing a total of 16 ID assignments. Two Quartet
housing frames cannot have the same address. However, a Quartet housing
frame, a Symphonie housing frame and a Solo housing frame can have the
same address.

3. Configure the workstation software to reflect the ID assignments of step 2.

on figure 3.12 below.

5. Replace the front panel. Make sure to rotate the thumb screws clockwise in
order to secure the front panel to the chassis.

N.B.: For proper cooling of the imaging modules do not leave the front door
removed for a long period of time when power is on.

3.11 imaging Extender Module

(

)

The optional imaging extender module allows easy access to any imaging series modules
requiring testing, repairs, or calibration. In order to install the extender module, remove the
imaging module under test from the housing frame. Replace it with the extender module.
Insert the module under test in the extender module making sure it is firmly installed. Refer
to the Figure 3.13.

To remove the module under test, simply push on the ejectors situated at the front of the
extender module and pull out the module under test. To remove the extender module,
carefully pull on it in order to detach it from the housing frame's rear motherboard.

For complete instructions on module installation and module removal, refer to sections 3.7
and 3.8 respectively.

4 Power Supply

4.1 Powering Up and Local Power Monitoring

To turn on power in a Quartet frame, remove the front panel and place the power switch in
the '1' position. The PWR indicator will light up. The following indicators provide information
on the power supply's status.

• PWR

The PWR LED turns on to indicate the housing frame is powered.

• FAIL

The FAIL LED turns on to indicate that at least one power supply voltage level has
failed. This may also occur after a thermal shutdown by the power supply. A thermal

shutdown occurs at a temperature of 70°C (158°F) setting all output voltage levels to 0.
The power supply will restart only when its temperature has dropped to at least 50°C
(122°F).

• O/L

This LED lights up to indicate a current overload has been detected on one of the DC
power lines. This indicates a problem with either the power supply or one of the housing
frame's modules.

4.2 Remote Power Failure Alarm and Cable Construction (optional)

)

The power supply remote monitoring feature in Quartet frames detailed in Table 1.1 informs
the user of a power supply problem. A power failure alarm is provided by the dry contacts
of the rear panel mini-Din 8 connector.

Figure 4.2 describes the pinout of the rear panel mini-Din 8 connector. The mini-Din 8
connector is viewed from the back where the actual wire connections are to be made. The
mini-Din 8 rear panel connector provides a normally closed contact and a normally open
contact. During normal operation, there is a closed contact between pins 1 and 7 and an
open contact between pins 2 and 7. If the power supply fails or experiences a current
overload, contact between pins 1 and 7 opens and contact between pins 2 and 7 closes.
