INSTALLATION
Introduction
This section describes how to install your Q6400 system with the minimum of fuss and time. The system
has been designed with the aim of being simple to install.
Unpacking
Carefully remove the equipment from the boxes and check it against the Packing List. This shows what
items have been shipped against your order and includes all options. Any error should be reported to your
supplier immediately. After you have unpacked the equipment please save all the packing material as this
could be useful in the future if the unit needs to be returned for maintenance.
Check each item supplied for transit damage. Any damage should be reported in detail to your supplier.
You must state the serial number of the unit (to be found on the rear or side of each unit).
Check that power cords supplied are suitable for your country and that the equipment has been set to the
correct mains (line) voltage. Note that standard remote panels are mains powered and must also be
checked. Instructions are to be found later in this section on how to change the voltage.
Do NOT change any DIP switch or rotary switch settings at this stage as these will have been correctly
set before leaving the factory.
Physical Installation
All frames are designed for mounting in standard 19" equipment racks. When preparing for installation
bear in mind that the modules are plugged in from the front and extra space is required for the modules to
mount on an extender module. You should allow at least 800mm clearance at the front for maintenance.
The depth of most router frames is 485mm plus connectors from the front of the equipment rack. In
addition allowance must be made for the high numbers of cables to be installed at the rear of the frame.
Power dissipation in most frames is relatively low and cooling is achieved by natural convection through
the sides of the frame. In the interests of long term reliability it is advisable, where possible, to leave a 1U
gap or to fit a unit with a depth of less than 200mm above every router.
The Q6400 Serial Digital Video Router, Q6400 Analogue Video Router, and Q6400 Analogue Audio
Router are fan cooled, drawing cool air from the front of the router and expelling it through the right
hand side vents.
In all cases, it is important to keep the apertures clear of obstructions e.g. cables.
Electrical Connections
This section shows the rear panel views of the Q6400 frames.
Video Inputs and Outputs
These connections are made using standard video 75Ωcoaxial cable. A high quality cable such as
PSF1/2 (TF3255) or PSF1/3 (TF3304) or equivalents should be used for optimum performance. It is both
important and good practice that cables are properly supported and not hanging on the connectors as this
can put unnecessary stresses on the connectors.

Quartz Q6400 System Manual
08 November 2005 Issue 6.00 Page 9
The video inputs are terminated within the equipment. The video outputs are dual outputs on Q6400-SV
systems.
The Q6400 (3U) Analogue Video Frame
The Q6400 (8U) Serial Video Frame
Video Reference
The Ref input is a looping input. Any video signal with standard syncs may be used as a reference signal
to determine when cuts are made during vertical (picture) blanking. Whilst a burst is not required the use
of colour black is the most commonly available signal and is preferred. This can be looped through into a
video input on composite video systems.

Quartz Q6400 System Manual
08 November 2005 Issue 6.00 Page 10
Mixed sync pulses of 2v amplitude may also be used. 4v pulses can be used but a modification is
required to the main video router module and involves the addition of a single 4.7K 5% resistor.
Note: If one of the looping input connectors is not used then a 75Ωterminator plug must be fitted on the
unused connector. Otherwise the level on the line will be twice that expected, and may cause incorrect
operation of other equipment attached to the line.
The Q6400-SV router has two looping reference inputs “REF-A” & “REF-B” intended to allow mixed
625 and 525 working. In a 625/50Hz only installation then the sync reference must be looped through
both pairs of connectors.
If no reference signal is connected then the unit will switch at random intervals at a rate of about 40Hz.
Audio Inputs and Outputs
The connections of the audio signals to the equipment are made using 50 way multi-way connectors.
One connector is used for 16 inputs and another for 16 outputs. The same type or polarity of connector is
used for inputs and outputs. A larger drawing is included at the end of this section.
Standard D50 pin-out
The mating halves of these connectors are PLUG types and available as options (AK-0006). They are not
supplied as standard because many customers prefer to buy their connectors in bulk and prepare the
cables in advance of the equipment being shipped.
Each connector has three pins for each signal: signal hot (+), signal cold (-) and screen. The same
pattern of wiring is used on all connectors, i.e. Input 1 is wired the same as Output 1. All the connectors
on the rear of the frames are sockets. It is sound analogue audio practice not to earth the cable screens
at both ends, as sometimes hum can be introduced owing to earth potential differences. However, with
digital audio is better to ground at both ends.
For unbalanced AES audio, standard video cable and frames with BNC connectors are used.

One frame can handle stereo signals. Four connectors are provided for the left or A1 inputs 1-16, 17-32,
33-48, and 49-64. Four connectors are provided for the left or A1 outputs 1-16, 17-32, 33-48, and 49-64.
These are then duplicated for the second audio channel. Above 64x64 this router can also be supplied in
mono only in matrix sizes up to 128x64.
The Q6400 (3U) Digital Audio Balanced AES Frame
For digital audio it is important to use data cable with a characteristic impedance of 110Ωrather than
audio cable. For error free transmission, care should be taken to ensure the cable losses are acceptable
over the intended length.
The unbalanced audio version of this product uses the Q6400-SV router frame shown earlier in this
section.

Quartz Q6400 System Manual
08 November 2005 Issue 6.00 Page 12
RS422 Data Routers
There are several different types of RS422 data router to support different applications. Port routers allow
any one connector to be routed to any one other connector, making a point-to-point connection. Matrix
routers have both input and output connectors that are permanently connected to either controlling
devices such as edit controllers or controlled devices such as VTR’s. See application note AN-0014 for
further information.
The Q6400-PR Port RS422 & RS232 Router
The Q6400-PR port router can be supplied with 16, 32, 48, or 64 ports. Extra ports can be added by
installing internal dual channel SIMM modules. Ports can work in an electronic ‘auto-sense’ mode to
correctly assign the RS422 Tx/Rx pairs to pins 3 & 6 or 5 & 4. This allows a mixture of controlling and
controlled devices to be connected through the port router with the minimum of effort.

Note A: The TX+/- and RX+/- pairs are assigned electronically and normally work in auto-sense mode to detect the type of device
connected to the port. Auto-sense mode can be disabled from WinSetup.
In some installations the auto-sense capability can cause problems. This is possible with controlled
(slave) devices that tri-state their RS422 drivers when not transmitting. This then stops the auto-sense
circuit from ever configuring the correct pin-out. If a direct connection between the controlling and
controlled device works but routing through the port routers does NOT work then try using WinSetup to
configure the controlled (slave) device port to have a fixed Tx/Rx pair. See WinSetup, Frame Dialog,
Frame System Data.

If one of the above Tx/Rx configurations does not work on the controlled (slave) device port then the
controlling (master) device port might also need to be configured to have a fixed Tx/Rx pair.

Remote Control - Q-link
All the frames and remote control panels are connected by a single coaxial link called Q-link. This link
uses standard 75Ωvideo cable daisy-chained from frame to frame and panel to panel. Each end of the
link must be terminated in 75Ω. A pair of connectors is fitted to the frames and the link looped through
them.
On frames with several Q-Link connectors the “Q-Link-1” or “Q-Link 1a/1b” is always available. The
extra Q-link connectors are only supported when a CI-0004 module is installed on to the FU-0003
processor. Only one connector is fitted on the panels and a T-piece needed to tap off the Q-link. In this
way a panel can be removed from service and replaced without disrupting the link, even temporarily.
This daisy chain method ensures the best transmission quality of the control signals down the cable.
Short cuts that might save cable, such as running stubs to some panels, are not recommended as this
may cause data errors under certain circumstances. The maximum cable length is shown in the
Technical Specification in Section 2 of this manual.
A total of 64 devices (V5 firmware) can be supported, normally organised as 16 frames and 48 panels.
Each unit connected to the Q-link has its own address switch that is set up as part of the system setup.
In medium sized systems it may be more suitable to have several Q-Links on the master frame and to
wire off in different directions. This requires a CI-0004 module in the master router.

Quartz Q6400 System Manual
08 November 2005 Issue 6.00 Page 15
In larger systems the extra processing power of the SC-1000 is often required. This is a separate 2U
controller that supports an optional backup controller and backup PSU. The large number of Q-Links
allows a system to be split into physical areas such as vision control, audio, production, and engineering.
As a system design guide the SC-1000 should be considered when the router grows above 128x128
single level or has more than 10-15 total Q-Link devices. See section 6.10 for further information on the
SC-1000.
In large buildings or outside broadcast vehicles (OB trucks) the Q-Link system can be affected by mains
earth differences between physically remote areas. This causes currents to flow in the outer of the Q-
Link cable that can disrupt the Q-Link communications. To prevent this problem Quartz can supply a SI-
0004 Q-Link opto-isolator unit.

Quartz Q6400 System Manual
08 November 2005 Issue 6.00 Page 16
In large buildings the SI-0004 would only be installed once a problem had been identified. In OB trucks it
is good practice to install an SI-0004 between the internal Q-Link and any external ‘tail gate’ or bulk head
patch panels. Multiple SI-0004 units can be used where several external Q-Links are required.
Refer to Application Note AN-0016 for further information on the SI-0004 interface.
Remote Control - RS232/422 Computer Port
The connectors (9 way D-type or RJ45 sockets) for the computer ports are fitted on the rear of each
router frame. All routers fitted with the FU-0003 processor have one computer port driver fitted, and this
normally connects to the ‘Computer’ or ‘Serial 1’ connector. Second serial ports may require a CI-0001 or
CI-0004 module to be installed, refer to the Router Options manual for further details.
For real time or high-speed control it is essential that the serial port on the master router be used. As Serial
1 is normally required to configure the routing system from WinSetup, Serial 2 would normally be used for
the high-speed connection and this requires a CI-0001 or CI-0004 module.
The Q6400-SV router has a four way backplane link to allocate the rear panel ‘Serial 2’ connector to either
the upper input module FU-0003 processor or the second serial port provided by the lower input module
CI-0001 or CI-0004 module. The factory default setting for these links is the RS-1 position.

All Quartz products use the same pin-out for the serial D9 connectors. The wiring of the connectors is
different for RS232 and RS422.

The computer port connector on the rear of a remote control panel only functions if a CI-0003 module is
installed. Controlling the routing system through a panel computer port is possible but is not
recommended, these ports are only provided for stand-alone S7 panels i.e. CP-3200-S7.

Alarm Connector
This connector allows remote sensing of a power supply failure in dual PSU systems or control processor
failure. The exact connection details vary depending on the product.
Product Alarm Functions
Q6400-AA Pins 1, 2 = Right PSU, Pins 3, 4 = Left PSU (viewed from front)
Q6400-AV Pins 1, 2 = Right PSU, Pins 3, 4 = Left PSU (viewed from front)
Q6400-DA-xxxx-B Pins 1, 2 = Upper PSU, Pins 3, 4 = Lower PSU
Q6400-DA-xxxx-D Pins 1, 2 = Upper PSU, Pins 3, 4 = Lower PSU
Q6400-SV Pins 1, 2 = Upper PSU, Pins 3, 4 = Lower PSU
Each PSU and the controller alarm is a relay with normally open contacts that are held closed for a
working system. An alarm will therefore be indicated for a fault, loss of power, or a disconnected/broken
cable. Alarm functions can be daisy-chained together to give a single alarm or wired back individually to
give more information.
Power
IEC connectors are used to supply power to frames and panels alike. Each connector has an earth pin
and as matter of safety this earth pin must be connected to a solid ground to ensure proper earthing of
the metalwork.
In the UK equipment is often supplied with a power cord suitable for wiring into a plug of the user's choice.
Please wire the plug using the colour code below:
Brown Live (Line or Phase)
Blue Neutral (Return)
Green/Yellow Earth (Ground)
Some of the frames are fitted with screw terminals so that the CHASSIS and TECHNICAL earth can be
wired to different earth points. The equipment is shipped with a wire link fitted between these terminals. If
the link is disconnected then it is imperative for personal safety that a proper earth connection is
established.
Setting the Power Line Voltage in the Frames and Panels
All Q6400 frames PSU’s are auto ranging and therefore do not need the power line voltage set.

Quartz Q6400 System Manual
08 November 2005 Issue 6.00 Page 19
Configuring The Frames
Winsetup and the configuration file largely define how the router frames work within a routing system.
Before using WinSetup some basic hardware parameters must be set up. This section describes how to
do this for all video and audio frames. The next section covers the same processes for the remote control
panels.
Note: The rotary hex and DIP switches are only read at power up or following a RESET. If you make any
changes you must press the RESET button so that the new settings are acted upon.
Frame Mode: Master or Slave
One matrix module in the system must be set as the Master and the others as Slaves. This is very
important, as there will not be proper communications unless this rule is followed. The Master frame
contains the non-volatile RAM (NVRAM) to store the complete matrix route status and the separate
NVRAM in which to store the setup or configuration of the system.

Serial Port Mode: Diagnostics or Protocol
The computer port can be set to diagnostics mode or protocol mode. Normally the setting is for
diagnostics mode so that the matrix outputs basic error logging information. Use this mode with the
WinSetup ‘PC Comms Window’ or any dumb terminal. The protocol mode is used if a computer is being
used to download a new system configuration from WinSetup, or if the matrix is to be controlled from an
external computer in a remote switching application.

Force Input: Force input or use battery back settings
The router system normally remembers the crosspoint settings after a power loss. In some situations it
may be preferable to restore the router to a defined input, say bars/tone, after a power loss. This switch
overrides the normal battery backed memory operation, but can only be set on the master router.

Address Switch
The rotary hex switches are used to set the unique address of the matrix modules in the frame. The
purpose of the switch setting is to ensure that each matrix module has a different code. This distinguishes
different frames in a multi-frame system so each is updated with the correct crosspoint settings. The
exact setting will depend on your WinSetup configuration.
A small screwdriver is needed to fit the slot and make the selection. Rotate the switches, which have 16
positions from 0 through 9, then A to F (hexadecimal notation).

Buzzer
The sounder fitted on most matrix modules is used to provide warnings when certain buttons on a local
panel are pressed. This can be enabled or disabled by moving a link adjacent to the buzzer.
Analogue Video Routers
The items covered in this section are specific to the analogue video routers.
Input Coupling Mode
Normally there is a dc restorer on each video input. These restore the sync tips (the lowest part of the
signal) to a voltage of -300mv. Then, irrespective of the dc or average picture level of the incoming
signal, the dc of the black level on the output will be constant.
