Quartz Q6400 System Manual 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.
Page 9: Video Reference
Quartz Q6400 System Manual 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.
Page 10: Audio Inputs And Outputs
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.
Page 11 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. 08 November 2005 Issue 6.00...

Page 14: Remote Control - Q-Link
Quartz Q6400 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 15 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.
Page 16: Remote Control - Rs232/422 Computer Port
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.
Page 17 Quartz Q6400 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.

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. 08 November 2005 Issue 6.00...
Page 19: Configuring The Frames
Quartz Q6400 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.
Page 20: Force Input: Force Input Or Use Battery Back Settings
Quartz Q6400 System Manual 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.
Page 21: Serial Digital Video Routers
Quartz Q6400 System Manual This is fine for composite video signals, but component video signals: Pr (V) and Pb (U) have the potential for signal content both above and below black level. A dc restorer is not suitable for such signals and the signal is dc coupled through the matrix.
Page 22: Winsetup
Quartz Q6400 System Manual WinSetup The WinSetup program is used to configure most of the routing functions, including control panel operation. It allows such things as the number of signal levels to be defined, which routing frames and panels are connected to the system, what the names are for the inputs and outputs.
Page 23: General Description
Backup power supplies are available as an option. Q6400 range handles up to 64 inputs and up to 64 outputs, with each signal format in a separate package ranging from 3U to 8U. Backup power supplies are available as an option.
Page 24 Quartz Q6400 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 25 Quartz Q6400 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 26: Control System
Quartz Q6400 System Manual Control System The microprocessor based control system activities are: • Read buttons and update displays on both local and remote control panels, • Respond to data received through the computer port • Update the router crosspoint switches.
Page 27: Dip Switches
Quartz Q6400 System Manual Router Address Switches : These switches set the high (upper four bits) and low (lower four Processor bits) of the 8 bit Q-Link address. Routers normally have the high switch set to zero giving routers an address range of 0x00 to 0x0f.
Page 28: System Control Bus: Q-Link
Router Options manual. Serial Digital Video Routing The Q6400 router uses two cards of 32 inputs each. These connect via the backplane to two 64x32 combined crosspoint and output cards. These routers are capable of handling signals in the following formats:...
Page 29: Analogue Video Routing
(PC-167) Inputs In the Q6400 routers there can be up to two modules each capable of handling up to 32 inputs. The input stages are mounted on plug-in SIMM modules. The re-clocking function is located on the output stage. This reduces costs in a router with less outputs i.e. 64x32.
Page 30 The signal path has been designed to be as short as possible. This reduces the variations in path length between channels and maintains the overall transparency through the router so important in broadcast applications. The 3U Q6400 frame is shown in schematic form below: PS-0012 PS-0012 Inputs 33-64 &...
Page 31: Analogue Audio Routing
Analogue Audio Routing The Q6400 router uses a single main module for 64 inputs and all the crosspoints. To this can be added output modules that are available in two formats. Two of these main modules can be fitted into a 3U chassis.
Page 32 Quartz Q6400 System Manual This output module has additional circuitry including a 4-to-1 switch. This allows a choice of four modes: normal audio output; silence to output; audio from the adjacent main module; and a mono mix of the audio from the adjacent and main module. With this module fitted the control system allows features such as stereo left/right swap, left to both outputs, right to both outputs, and left+right mix to either output.
Page 33: Aes/Ebu Digital Audio Routing
The Q6400 router allows a 64x64, using two cards of 32 inputs each. These connect via the backplane to two 64x32 combined crosspoint and output cards. The Q6400 is available in an 8U BNC frame providing the 75Ω AES3-ID coaxial interface, or a 3U D50 frame providing the standard 110Ω...
Page 34: Rs422 Control Level Routing
IDLE route. There are currently two sizes of RS422 port router, the Q32-PR and Q6400-PR. Port routers treat all the RS422 RJ45 connectors on the rear panel as general connectors, i.e. neither inputs nor outputs.
Page 35: Power System
Cooling Fans Q6400-SV (8U frame): These have a cooling fan fitted in the rear of the plug in PSU module that draws cool air from the front of the router and expels it through the right hand side vents. It is powered from both power modules, so that if either fails then it continues to run.

Page 42: 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 Q6400 products use modern high stability components, have a conservative design, and have low heat dissipation. Therefore there are no user alignments needed. 08 November 2005 Issue 6.00...
Page 43: Routine Maintenance
Quartz Q6400 System Manual Routine Maintenance The only items requiring routine maintenance are the cooling fans fitted in some matrix frames. Where the fan has a filter, this should be cleaned periodically. The fans used are rated at 50,000 hours so one can expect to replace them after five years.
