Q1601 & Q1602 System Manual
V1.64 5
DESCRIPTION
INTRODUCTION
The Q1601 and Q1602 are small routing switchers ideal for monitoring and emergency
switching applications. The Q1601 is 16x1 and the Q1602 16x2; versions are available
for both sizes to cover most signal formats including combined video and audio routers in
the same 1U frame.
The Q1602 model has an internal mains/line power supply (PSU). The Q1602E uses one
or two external power ‘bricks’ (PSU’s) to convert mains/line voltages to low voltage DC
and this allows the Q1602E series to support a backup PSU.
All models are available as a high definition, serial video, or analogue video base model
complete with a main video module, a single power supply, and a standard controller.
Options include an audio module, backup PSU (Q1602E only), passive local or remote
panel, and a separate Advanced Controller module, which offers more control
functionality.
Units may be stacked together so that for instance three video units could be used to
provide a component analogue video router. This application is called Stack Mode.
With the standard controller, a local control panel may be attached in place of the blank
front panel or a passive remote panel connected to the rear of the unit.
With the Advanced Controller option installed the full range of control features of the
larger Quartz routers become available. The most obvious benefit of this option is that
any of the standard Quartz remote control panels can be connected to the router via the
Q-Link.
Another major benefit of the Advanced Controller is that several routers can be combined
to appear and operate like a single router with a large number of inputs. This application
is called Cascade Mode.
ANALOGUE VIDEO
A single main module is fitted to the base of the chassis. The video and control
connectors are of the right-angle variety and protrude through apertures in the rear of the
chassis for cabling.
The video inputs are terminated in 75Ωand dc coupled, enabling it to handle composite or
component signals. The output amplifiers are adjustment-free with a bandwidth to over
100MHz. In the 16x1 model there are four output feeds but in the 16x2 model there are
twin output feeds of the signal.
Switching occurs during the vertical blanking interval of the signal on Input 1.
SERIAL VIDEO (SD)
The matrix is capable of handling signals in the following formats:
143Mb/s D2 NTSC composite
177Mb/s D2 PAL composite
270Mb/s D1 component
360Mb/s future wide screen applications
The serial video inputs are terminated in 75Ωand fed to an input receiver circuit that
provides equalisation for losses, mainly at high frequencies, to serial video signals that
have travelled down long cables. This equalisation varies automatically to suit the length
and type of video cable used. The output stage re-clocks the signal from the crosspoint
so that the correct pulse widths and timings are regenerated. It automatically selects the
correct sample rates from those mentioned above. The output amplifiers are designed to
drive 75Ωvideo cables. Output 1 has twin feeds but the second output has just one feed
of the signal.

Q1601 & Q1602 System Manual
6 V1.64
Vertical interval switching is referenced to the Sync Input and complies with SMPTE RP-
168.
HIGH DEFINITION VIDEO (HD)
The matrix is capable of handling signals in the following formats:
1.485Gb/s
1.485/1.001Gb/s
The serial video inputs are terminated in 75Ωand fed to an input receiver circuit that
provides equalisation for losses, mainly at high frequencies, to serial video signals that
have travelled down long cables. This equalisation varies automatically to suit the length
and type of video cable used. The output stage re-clocks the signal from the crosspoint
so that the correct pulse widths and timings are regenerated. It automatically selects the
correct sample rates from those mentioned above. The output amplifiers are designed to
drive 75Ωvideo cables. Output 1 has twin feeds but the second output has just one feed
of the signal.
Vertical interval switching is referenced to the Sync Input, which can be either HD tri-level
sync or standard sync (complies with SMPTE RP-168).
ANALOGUE AUDIO
This module fits above the main video module. It is installed from above and connects to
the main module via a single ribbon cable for power and control. It is fixed in place with
the audio connectors accessible from the rear of the unit. It is a dual channel module so
video and stereo audio is available within a single unit.
The inputs are electronically balanced to provide a high common mode rejection over a
wide frequency range. The input connectors are two D50 multi-way types and outputs
are a single D15. The output stages are balanced and the insertion gain so accurately
maintained that no adjustment is required. A jumper link for each output is provided to
correct the gain when driving into 600Ωloads. If it is necessary to drive unbalanced loads
then just one of the output lines and 0V are used, resulting in a 6dB drop in level.
AES/EBU DIGITAL AUDIO
This module fits above the main video module. It is installed from above and connects to
the main module via a single ribbon cable for power and control. It is fixed in place with
the audio connectors accessible from the rear of the unit. This unit supports the standard
110ΩAES3-1992 interface.
The audio inputs and outputs are transformer coupled and the connectors are a D50 multi-
way type for inputs and a D15 for the outputs.
For applications using the SMPTE 276M 75ΩAES3-ID coaxial interface a standard video
router can be used. Contact the factory for more details about this application.
POWER SYSTEM
The Q1602 model has an internal mains/line power supply (PSU). The Q1602E uses one
or two external PSU’s to convert mains/line voltages to low voltage DC and this allows
the Q1602E series to support a backup PSU.
There are no ac power switches fitted to the equipment as these products are normally
installed in permanent installations and power switched to whole equipment racks by
overall power switches. This reduces the risk of a unit being switched off inadvertently.
The Q1602 power IEC inlet connector is fitted on the rear panel and incorporates a fuse.
The correct ac power for the country in which the unit is used is selected automatically by
the internal PSU. The internal PSU consists of a self-contained switch mode supply that
converts nominal 110v or 230v ac to DC power at +5V, +/-15V. These clean DC voltages
are used directly by the router modules.

Q1601 & Q1602 System Manual
V1.64 7
When power is applied to a Q1602 the front panel indicator will be on (Green).
The Q1602E external PSU is fitted with a mains/line IEC inlet and converts the nominal
110v or 230v ac to DC power at 12V. A 2m flying lead terminated with a two pin locking
low voltage connector is then used to connect this 12V supply to the Q1602E. An internal
PSU converts the +12V to +5V, +/-15V. These clean DC voltages are used directly by
the router modules.
The Q1602E front panel indicator operation depends on an internal ‘PSU’s Fitted’ link,
located on the front of the right hand internal voltage converter module. If the ‘PSU’s
Fitted’ link is set to position ‘1’ then the front panel LED will be on (Green) when power is
applied. If the link is set to position ‘2’ then the LED will be on when both external PSU’s
are connected and powered up, and flashing if one fails.
Options that can be ordered for use with the Q1602E are:
Backup or spare power supply QT-PS
PSU mounting bracket, main/right QT-TR
PSU mounting bracket, backup/left QT-TL
STANDARD CONTROL SYSTEM
With the standard control system fitted the remote control port supports passive panels.
These are panels in which each push button switch and its associated LED is connected
to a single pin of the remote control connector. Thus the connector has one pin for each
button/LED plus pins for power and 0V. When a button is pressed the control pin goes to
0V sending a command to the router where, if accepted, it is latched to a low state (near
0V) so that when the button is released the LED stays lit.
A series of jumper switches can be set up to determine how the unit operates. Refer to
Page 18 in the Installation section for details of what they do and how they are set.
STACK MODE
When 16x1 routers are stacked for, say a component (YUV or RGB) analogue video
router then the remote control port on the rear of each unit is wired externally in parallel
and to the passive remote control panel, if used. For similar 16x2 applications the
Advanced Controller is required.
ADVANCED CONTROL SYSTEM
INTRODUCTION
By fitting the optional FU-0003 controller module the full range of control features of the
larger Quartz routers become available, resulting in the following major benefits:
1. Any standard Quartz remote panel can be connected to the router.
2. It is possible to connect this router into a larger Quartz routing system so that, for
instance, it could provide output monitoring for another much larger router.
3. Several 16x2 routers can be stacked, e.g. three routers to handle component
analogue video signals. This is called Stack Mode.
4. Up to seventeen routers can be stacked to provide a router of up to 256x1 for large
monitoring applications. In this application, called Cascade Mode, up to sixteen
upstream routers are cascaded into a seventeenth downstream router which is
designated the master and which is equipped with the Advanced Controller option.
With this option fitted the rear control connector changes function and becomes a
data bus feeding control commands from the downstream/master router to the
upstream ones.

Q1601 & Q1602 System Manual
8 V1.64
5. The FU-0003 Advanced Controller supports an RS232/422 port, enabling the router to
be controlled from another piece of equipment. On the earlier FU-0001 this required a
further option CI-0001.
6. Crosspoint status is maintained while the unit is powered down.
With this option fitted it is possible to reconfigure the system using the Quartz WinSetup
Windows software package.
The option is currently supplied under the part number FU-0003.
THE Q-LINK SYSTEM
Q-link is used to interconnect the panels and router frames using a single coaxial cable,
making it very easy to install. A total run of over 500 metres of standard video cable can
be used between panels and the frames.
The Q-link is daisy-chained from one panel to the next and between router frames. The
link must be terminated with 75Ωat both ends, standard video practice. One or two
hex switches in each unit set the identity of each so that they are correctly addressed by
the control system. Up to 32 devices can be supported.
The Q1601 and Q1602 routers, when equipped with the Advanced Controller, and the
standard remote panels have a single Q-Link BNC connector so a T-piece is used to tap
off the Q-link signal into the units. In this way a unit can be removed from service without
the Q-link being interrupted, even momentarily.
SERIAL PORT
The serial port is used to connect to computers or other third party equipment. This
feature is available when the Advanced Controller option is fitted, processor FU-0003.
CASCADE MODE
When the Advanced Controller option is fitted several routers can be connected together
to appear like a much larger router, for instance a 76x1 router can be built from five 16x1
routers, or a 30x2 router can be built from two 16x2 routers. The outputs of the upstream
routers are cascaded into the downstream router, which acts as a master controller for
the system. In this application the Advanced Controller is installed in the downstream
router only.
These techniques are applicable to video, audio and audio-follow-video mixed routers.
The only limitation with this system is that the levels of the second destination of an ‘nx2’
router are always married.
The following table gives the maximum sizes that can be achieved by cascading a
number of Q1602 routers together.

LOCAL CONTROL PANEL
On units with the standard controller the local panel is the CP-1601A-LP. It has sixteen
grey buttons for source selection and a yellow button, which can be used either as a Lock
or Enable button or to switch control between the two destinations, if fitted. These
choices are made using jumper links inside the unit. See Page 31.
On units with the Q-Link Option then the local panel is the CP-1600A-LP.
This has more buttons and a display so it can support sixteen sources, two destinations,
four levels of breakaway and a Lock function. Refer to Quartz manual MANUAL-05 for
details of the Q-Link control panels and their operation.
REMOTE CONTROL PANELS
If the standard controller is fitted then the standard passive panel available with this
product is the CP-1601A-P.
This is functionally identical to the CP-1601A-LP local panel, mentioned above. As there
are no high voltages within the unit and as the panel is benign from the EMC point of view it
is packaged without a rear cover.
Just one remote panel may be used but it can be set up to control both destinations, if fitted.
Note the local panel and remote panel connectors are directly wired together internally pin
for pin so that the two panels if used together will always follow each other exactly.
If the Advanced Controller option is installed then the rear panel control connector is not
available for connection to passive remote panels so panels using Q-Link must always be
used and their operation is determined by the configuration of the master unit in the
system. Refer to Quartz manual MANUAL-05 for details of the Q-Link control panels and
their operation.

INSTALLATION
This section describes how to install the system with the minimum of fuss and time. The
system has been designed with the aim of being simple to install; we trust that you will
agree.
UNPACKING
Remove the equipment carefully from the boxes and check against the Packing List
supplied with each unit. 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. Note that some remote
panels are mains powered and must be set to the correct mains (line) voltage.
PHYSICAL INSTALLATION
REMOTE PANELS
The passive remote panels are extremely shallow (45mm) and standard panels are
130mm deep plus cables. All remote panels are designed to fit into standard 19"
equipment racks and can be mounted at any angle.
ROUTER FRAMES
All units are designed for mounting in standard 19" equipment racks. The depth of the
frame is 280mm plus connectors. In addition allowance must be made for the high
numbers of cables to be installed at the rear of the frame.
Power dissipation in all units is low and cooling is achieved by natural convection.
Q1602 models will have the IEC mains/line plugged directly into the rear of the frame.
Q1602E models have and external PSU and this can be mounted on the optional rear
mount power supply tray if preferred, available in left hand and right hand versions.
These trays must be fitted to the Q1602E chassis before installation in the equipment
rack.

ELECTRICAL CONNECTIONS
The view of the rear panel shows the connections.
Figure 1: Rear View of Q1601 and Q1602 Routers
Figure 2: Rear View of Q1601E and Q1602E Routers
VIDEO INPUTS AND OUTPUTS
These connections are made using standard 75Ωvideo coaxial 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 and possibly reduce their working life.
On the Q1601-AV the four output feeds are provided on the two connectors marked OUT
1, J1 and J2. On the Q1602-AV the pair of OUT1 connectors are for the twin feeds of
Output 1 and J1 & 2 for those of Output 2.
On the Q1601-SV and Q1602-SV J2 is used for the SYNC Input, OUT 1 for the twin
feeds of the signal from Output 1 and J1 for the single feed from Output 2.
VIDEO SYNC
Analogue video routers take their switching reference signal from Input 1.
Serial Video routers have a separate terminating Sync input J2 that takes any standard
analogue video signal with standard sync. Mixed sync pulses of 2V amplitude may also
be used.
High Definition routers have a separate terminating Sync input J2 that takes either tri-
level sync or any analogue video signal with standard sync.
If no reference signal is connected then the unit will make crosspoint changes 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 input connector is used for each audio channel. The outputs are
accessible on a single D15 connector.
The matching cable connectors are all PLUG types. An accessory kit AK-0010 contains
a full set of matching halves of the audio and control connectors used on this equipment.
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.

Q1601 & Q1602 System Manual
V1.64 13
Each connector has three pins for each signal: signal hot (+), signal cold (-) and screen.
Figure 3 below shows how the cables are wired into the mating plugs. It is good analogue
audio practice to earth the cable screens at one end only, as hum can sometimes be
introduced owing to earth potential differences. However with digital audio it is better to
ground at both ends. For digital audio it is important to use data cable with 110Ω
characteristic impedance rather than audio cable. For error free transmission care
should be taken to ensure the cable losses are acceptable over the intended length.

In Stack Mode one control panel is connected to more than one router and so it is
necessary to use a daisy chain cable that links all the units together. Note that one router
and one router only must be used to provide power to the panel, therefore pins 22 & 23
must be connected to one router only.
The Sync signal on pin 21 is a control signal used to interconnect several routers
ensuring that they all switch in the same TV field or frame. This pin is not used in the
passive panels and so it is acceptable for the pin to be wired in the cable to all units.
These pins have a different function when the router has an Advanced Controller.

REMOTE CONTROL - USING Q-LINK
If the Advanced Controller option is fitted then all the Q1601 and Q1602 routers fitted with
this option, standard routers and standard remote control panels can be connected
together by a single coaxial link called Q-link. This link uses standard 75Ωvideo cable
daisy-chained from frame to frame and from panel to panel over a maximum cable length
of 500m. Each end of the link must be terminated in 75Ω. The installer must fit a 75Ω
terminator at each end of the cable.
Only one connector is fitted on each unit and a T-piece needed to tap off the Q-link. In
this way a unit 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 under certain circumstances cause data errors.
The system can support up to 32 devices. Each unit being connected to the Q-link has
its own address switch, which is set up as part of the system configuration.
RS232/422 SERIAL PORT
The D9 connector on the rear of the router functions only if the Advanced Controller
option has been installed. If the Advanced Controller option is the FU-0003 controller
module then the serial port is included. Early units, however, have the FU-0001
controller, in which case the CI-0001 Serial Card is required.
RS422 or RS232 Mode
The FU-0003 controller has a jumper link to select either RS232 or RS422. Set the link
to 232 or 422 as appropriate.
External Connections
The router has been built to minimise RF emissions. It is important you use tin and
dimple D-type connectors with metal shells connected to the screen of external cables in
order to achieve low RF emissions from this equipment. The shells are fixed by screw
locks with 4-40 UNC threads.
The Computer Interface connector on the equipment is a D-Type 9 socket using the pin
connections shown below. The wiring of the connectors is different for RS232 and
RS422.

CASCADE MODE
In this application several routers are connected together to appear like a much larger
router. The output of each of the upstream routers is connected to an input of the
downstream router. In this way it is possible to build a 256x1 router or a 128x2 router.
Q1601 Cascade
This allows a maximum router size of 256x1 to be built. In the example below a 48x1
router can be built from four 16x1 routers. The outputs of the three upstream routers are
cascaded into the downstream router, equipped with an Advanced Controller module,
which acts as a master controller for the system.

Cascade Control
From a control point of view it is necessary to install the Advanced Controller module in
the downstream router. This unit then connects to the Q-link just like any other Quartz
router, communicating to the other routers and remote control panels.
The downstream router sends commands in parallel digital form through a cable
connected to the CONTROL connector, which is daisy-chained to the upstream routers.
When commands are received from the control panels they are processed in the
Advanced Controller in the downstream router. It then sends commands to its own
crosspoints to make a new route selection, but simultaneously sends commands out of
the CONTROL connector to the upstream routers. If a new route selection requires a
source from a different upstream router from that currently selected then a command is
sent through the CONTROL connector to all the upstream routers, which switch in
tandem to the new input at the same time as the downstream router.
This technique is applicable to video, audio and audio-follow-video mixed routers. The
only limitation to this is that the levels on the second destination are always married.
Note that the analogue video router takes its switching reference point from the signal on
Input 1. It is therefore important in a cascade application that all the inputs of the
upstream router feeding Input 1 of the downstream router have valid video signals,
otherwise video switching will not occur in the vertical blanking interval.

POWER
IEC connectors are used to supply power to the router frames, external PSU’s, and
panels. Each connector has an earth pin and as matter of safety this earth pin must be
connected to a solid ground to ensure a proper earth connection.
Q1602E models use an external PSU and therefore the router chassis metalwork will not
be directly connected to earth. A separate chassis earth point is provided for users that
require equipment to be earthed.
All power cords are supplied with a mains plug suitable for the country of use (where
known). Should it be necessary to change the mains plug please wire the plug using the
colour code below:
Brown Live (Line or Phase)
Blue Neutral (Return)
Green/Yellow Earth (Ground)
There is no power switch on the unit so it is essential that the power cord be removed
before commencing to service the unit.
SETTING THE POWER LINE VOLTAGE
On units with no voltage selector the PSU is auto-ranging and no adjustments are
required.
SETTING THE Q1602E PSU LINK
On Q1602E models the internal ‘PSU’s Fitted’ link must be set to match the number of
external PSU’s connected, either 1 (main) or 2 (main plus backup).
The ‘PSU’s Fitted’ link controls the action of the PSU Status LED and the Front Panel
power on LED and is located on the front of the right hand internal voltage converter
module. If the ‘PSU’s Fitted’ link is set to position ‘1’ then the front panel LED will be on
(Green) when power is applied. If the link is set to position ‘2’ then the LED will be on
when both external PSU’s are connected and powered up, and flashing if one fails.

SW1-8 Up=Frame, Down=Field
Note on SW1-3: When a FU-0003 processor controls the router module, this setting optionally
switches all levels (video, audio1, and audio2) from the video ‘take’ i.e. married levels. This
functionality is not required as the configuration can control this aspect of operation so it should be left
in the Normal/Up state.
TV LINE SWITCHING
Serial Video Router
Switching complies with the SMPTE RP-168 standard (525 = line 10/273, 625 = line
6/319). It is also possible to choose whether to permit switching on every TV field or only
on the first field of each picture, important in certain editing applications, using SW1-8.

The Sync signal is derived from Input 1, so it is important that a valid signal is provided at
this input, otherwise video switching will not occur in the vertical blanking interval. Note
that in a cascade application all the inputs of the upstream router feeding Input 1 of the
downstream router must also have valid video signals.
