Page 8: Audio Inputs And Outputs
Each connector has three pins for each signal: signal hot (+), signal cold (-) and screen. The same pattern of wiring is used on all connectors (except Q16-AA-1604 and 1608, see above), 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.
Page 9 Asynchronous (crash switch) Q16-DA-1616-US Synchronous (soft switch and shuffle) Synchronous Digital audio router Q16-DA-1616-US must have an AES or video reference connected for proper operation. The video or unbalanced AES reference signal is connected to the BNC reference connector. On the digital audio main router module 3 links must be correctly set to enable the reference circuits.

Page 11 Quartz Q16/Q32 System Manual For digital audio it is important to use data cable with a characteristic impedance of 110Ω rather than audio cable. For error free transmission, care should be taken to ensure the cable losses are acceptable over the intended length.
Page 12: Rs422 Data Routers
Quartz Q16/Q32 System Manual 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.
Page 13 Quartz Q16/Q32 System Manual The Q1600-RR-1600 Port RS422 or RS232 Router The internal design of the Q1600-RR port router uses a relay matrix. This means that the D9 connector signal pins 2, 3, 7, 8 have no specific function and pin 2 of one connector is connected to pin 2 of a corresponding connector when a route is made.
Page 14: Relay Routers
Two pole routers support two independent signals or one pair of signals. Four pole routers support four independent signals or two pairs or signals. The chassis sizes are the Q16 (1U) supporting matrix sizes up to 16x8 and the Q32 (2U) supporting matrix sizes up to 16x16. The Q32 chassis also supports a redundant PSU where required.
Page 15 Quartz Q16/Q32 System Manual Outputs 1-8 appear on the J4 connector signals 1-8. Outputs 9-16 (Q32-RR-1616-xx only) appear on the J8 connector but also using signals 1-8. 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.
Page 16: Remote Control - Q-Link
Quartz Q16/Q32 System Manual 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 75Ω video cable daisy-chained from frame to frame and panel to panel. Each end of the link must be terminated in 75Ω.
Page 17 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.

CI-0001 or CI-0004 module. The Q16 range of routers only support one serial port due to limited rear panel space. The Q16 and Q32 routers have a link on the backplane to allocate the rear panel Q-Link BNC connectors to looping single Q-Link or dual Q-Link operation.
Page 19: Alarm Connector
Quartz Q16/Q32 System Manual All Quartz products use the same pin-out for the serial D9 connectors. The wiring of the connectors is different for RS232 and RS422. RS-232 RS-422 TX 0V RX 0V Not Used Not Used Not Used Not Used The cable between the PC and the router (RS232) only needs to use TX, RX, and GND as shown below.
Page 20 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 On all Q16/Q32 products the PSU is auto ranging and the power line voltage does not need to be set. 18 May 2004 Issue 5.00...
Page 21: Configuring The Frames
Quartz Q16/Q32 System Manual 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.

Quartz Q16/Q32 System Manual switch overrides the normal battery backed memory operation, but can only be set on the master router. The DIP-4 switch is used for this function. Set DIP-4 switch UP = Battery backed memory DOWN = Force to input (WinSetup) Press the RESET button to accept the new setting.

Quartz Q16/Q32 System Manual TV Line Switching Sometimes it is important to change the TV line in the vertical-blanking interval during which the routing switcher makes its cuts. Any line from 6/319 to 10/323 may be selected using the three jumper links LK6, 7, 8.
Page 24: General Description
GENERAL DESCRIPTION Introduction This section describes features of the Q16 and Q32 routing systems and how to apply them in your own particular situation. The Quartz range of routing switchers handles virtually all signal formats in sizes from 16x1 to 1024x1024.
Page 25 Quartz Q16/Q32 System Manual Units are stacked together to provide multiple levels. E.g. a system could be provided with serial digital, composite video, three levels of component video, four levels of audio, time code and RS422. Remote control panels are usually supplied as part of a system and these are connected back to the routers by a standard video co-ax cable called Q-Link.
Page 26: Control System
Quartz Q16/Q32 System Manual 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. A variety of other options may be supplied. These include additional RS232/422 Computer Interface Cards to communicate with computers, Parallel Interfaces for connection to custom control panels, or a Video Status Display to show on a TV picture monitor how the routes have been assigned.
Page 27: Embedded Control: Fu-0003
Quartz Q16/Q32 System Manual The system is configured before shipment to make it work in the unique way required by each customer. This configuration is generated by the WinSetup program and downloaded to the master router, where it is stored in non-volatile memory (NVRAM).

Quartz Q16/Q32 System Manual Router Baud Rate (DIP-1) : This switch forces default baud rate (9600 or 38400), or allows the user to define a baud Processor rate using WinSetup. Up=Default, Down=User defined. Computer Port (DIP-2) : This switch sets the mode of operation of the computer port between diagnostics or protocol mode.

Router Options manual. Local Control Panel This panel is available only on 1U frames, mainly Q16 units. The design of the panel is similar to the CP-1600A remote panel and can be ordered as CP-1600A-LP. It can be fitted to the front of the frame. This saves an extra rack unit when a panel is required adjacent to the rack, perhaps for engineering use and, because it shares the electronics hardware in the main unit, it is of lower cost than the CP-1600A remote panel.
Page 30: Analogue Video Routing
Matrix On the Q16 system a single crosspoint chip selects the 16 inputs to the 16 outputs. This is mounted on a small PCB assembly. On the Q32 system a similar assembly replaces this containing two crosspoint chips to select the 32 inputs to the 32 outputs.
Page 31: Analogue Audio Routing
Analogue Audio Routing In the Q16 the main audio router card provides a two level 16x16 matrix (Stereo or A1, A2). The card may be controlled as two levels for split (breakaway) audio or together with the first level (married), according to how the system is set up.

Page 35: Q1600-Rr-1600
Power System 1U frames, mainly Q16 units, can only have a single power supply. All other frames have the option of dual supplies to protect against the failure of one of the supplies or, equally likely the loss of incoming ac power.
Page 36 Quartz Q16/Q32 System Manual Remote panels are used to indicate current routes and to make new route selections at various locations to suit the user. Most panels are connected to the frame via the 'Q-link' coaxial link. The identity of each panel is determined by the unique setting of a rotary hex switch in each panel.

Page 43: Some Common Faults
Further fault finding will usually involve the use of schematic diagrams and optional extender modules. This should be entrusted to an experienced technician. Alignment The Q16/Q32 products use modern high stability components, have a conservative design, and have low heat dissipation. Therefore there are no user alignments needed. Routine Maintenance The only items requiring routine maintenance are the cooling fans fitted in some matrix frames.
