1. OVERVIEW
The SC-500E system controller is a platform designed to manage all communication and interface
requirements for small to medium routing systems.
Housed in a 1RU frame the SC-500E system controller manages the communication between multiple
Evertz/Quartz products and third party equipment. It can also be configured to provide communication
translations between Q-Link, RS-422/RS-232 and Ethernet.
The SC-500E is powered from a single external power supply that connects to the frame via a secure
bayonet locking connector. A redundant external power supply can also be fitted if required.
The SC-500E in its standard configuration provides two Q-Link ports, two RS-422/RS-232 serial ports
and a single Ethernet port. There are also two additional ports that can be used as a Q-Link port or a
RS-422/RS-232 serial port.
The SC-500E is capable of supporting up to 32 router control panels simultaneously. The panels can
be connected to the SC-500E via Q-Link, Ethernet, or a mixture of both.
The SC-500E is capable of controlling up to 16 independent routers on 16 individual levels.

1.2. DEFINITIONS
4:2:2: The sampling ratio used in the HDTV digital video signal. For every 4 samples of
luminance there are 2 samples each of R-Y (Red minus Luminance) and B-Y (Blue
minus Luminance).
16x9: A wide screen television format such as HDTV in which the aspect ratio of the screen
is 16 units wide by 9 high as opposed to the 4x3 of normal TV.
AES/EBU: (Sometimes abbreviated as AES) Refers to the digital audio standard (AES3-1992) set
by the Audio Engineering Society and European Broadcast Union, and used by most
forms of digital audio from CDs to professional digital video.
ASPECT RATIO: The ratio of width to height in a picture. Theatre screens generally have an
aspect ratio of 1.85 to 1, widescreen TV (16x9) is 1.77 to 1, and normal TV (4x3) is
1.33 to 1.
CCIR (International Radio Consultative Committee): An international standards committee. (This
organization is now known as ITU.)
CCIR-601: See ITU-R601.
CLIFF EFFECT: (Also referred to as the ‘digital cliff’) This is a phenomenon found in digital video
systems that describes the sudden deterioration of picture quality when due to
excessive bit errors, often caused by excessive cable lengths. The digital signal will
be perfect even though one of its signal parameters is approaching or passing the
specified limits. At a given moment however, the parameter will reach a point where
the data can no longer be interpreted correctly, and the picture will be totally
unrecognizable.
COMPONENT ANALOG: The non-encoded output of a camera, video tape recorder, etc.,
consisting of the three primary colour signals: red, green, and blue (RGB) that together
convey all necessary picture information. In some component video formats these
three components have been translated into a luminance signal and two colour
difference signals, for example Y, B-Y, R-Y.
COMPONENT DIGITAL: A digital representation of a component analog signal set, most often Y,
B-Y, R-Y. The encoding parameters are specified by ITU-R709 for HDTV signals.
SMPTE 274M and SMPTE 296M specify the parallel interface.
COMPOSITE ANALOG: An encoded video signal such as NTSC or PAL video that includes
horizontal and vertical synchronizing information.
COMPOSITE DIGITAL: A digitally encoded video signal, such as NTSC or PAL video that
includes horizontal and vertical synchronizing information.

SC-500E System Controller
Page 4 Revision 1.0
DROP FRAME: In NTSC systems, where the frame rate is 29.97002618 frames per second, the drop
frame mode permits time of day indexing of the frame numbers by dropping certain
frame numbers. Specifically frames 0, and 1 at the beginning of each minute except
minutes 0,10,20,30,40, & 50, are omitted, to compensate for an approximate timing
error of 108 frames (3 seconds 18 frames) per hour. A flag bit is set in the time code
to signal when the drop frame mode is in effect.
EBU (European Broadcasting Union): An organization of European broadcasters that among
other activities provides technical recommendations for the 625/50 line television
systems.
EMBEDDED AUDIO: Digital audio is multiplexed onto a serial digital video data stream.
ITU: The United Nations regulatory body governing all forms of communications. ITU-R
(previously CCIR) regulates the radio frequency spectrum, while ITU-T (previously
CCITT) deals with the telecommunications standards.
ITU-R601: An international standard for standard definition component digital television from
which was derived SMPTE 125M and EBU 3246-E standards. ITU-R601 defines the
sampling systems, matrix values and filter characteristics for Y, B-Y, R-Y and RGB
component digital television signals.
NTSC: National Television Standards Committee established the television and video
standard in use in the United States, Canada, Japan and several other countries.
NTSC video consists of 525 horizontal lines at a field rate of approximately 60 fields
per second. (Two fields equals one complete Frame). Only 487 of these lines are used
for picture. The rest are used for sync or extra information such as VITC and Closed
Captioning.
PAL: Phase Alternating Line. The television and video standard in use in most of Europe.
Consists of 625 horizontal lines at a field rate of 50 fields per second. (Two fields
equals one complete Frame). Only 576 of these lines are used for picture. The rest are
used for sync or extra information such as VITC and Teletext.
PIXEL: The smallest distinguishable and resolvable area in a video image. A single point on
the screen. In digital video, a single sample of the picture. Derived from the words
picture element.
SMPTE (Society of Motion Picture and Television Engineers): A professional organization that
recommends standards for the film and television industries.
SMPTE 12M: The SMPTE standard for Time and address code. SMPTE 12M defines the
parameters required for both linear and vertical interval time codes.
SMPTE 125M: The SMPTE standard for bit parallel digital interface for component video signals.
SMPTE 125M defines the parameters required to generate and distribute component
video signals on a parallel interface.

2. INSTALLATION
2.1. 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 which can be found on the rear of the frame. Check that
power cords supplied are suitable for your country and that the equipment is compatible with your
mains (line) voltage.
The SC-500E range uses a common external PSU ‘brick’ that is auto-ranging and converts nominal
115V or 230V AC mains voltages to safe 12V DC. This then connects to the SC-500E where any
internally required voltages are generated. The external PSU has an IEC inlet and approximate 1.7m
of DC lead terminated in a two-pin bayonet style connector.
IEC connectors have an earth pin and as a matter of safety this earth pin must be connected to a solid
ground to ensure a proper earth connection.
In the UK, equipment is supplied with a power cord already fitted with a 3 pin mains plug. Should the
lead be re-wired then please make connections 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 is removed before
commencing to service the unit.
All SC-500E PSU’s are auto-ranging and no adjustments are required.
2.2. PHYSICAL INSTALLATION
2.2.1. System Controller
All units are designed for mounting in standard 19” equipment racks. The depth of the frames is 260mm
(approx.) excluding connectors. In addition, allowance must be made for the cables to be installed at
the rear of the frame.
Overall power dissipation is very low and cooling is by natural convection.
Do not place the SC-500E directly above very hot equipment or in sealed equipment racks that are not
adequately cooled.

SC-500E System Controller
Revision 1.0 Page 7
2.3. ELECTRICAL CONNECTIONS
Figure 2-1: Rear View of SC-500E
2.4. STANDARD CONFIGURATION
The following are the standard options that are supplied with the unit. Further options can be added
depending on the system requirements.
2.4.1. Power 1 PSU 12VDC Input
This is the main 12 Volt DC input. The SC-500E is supplied with the external power supply unit (PSU)
QT-PS. Before using, please check that you have been supplied with the correct unit. The PSU does
not contain any serviceable parts and for safety reasons should not be opened as there is a significant
risk of electric shock. A redundant external power supply can also be fitted, if required (see section
2.5).
2.4.2. Q-LINK 1, Q-LINK 2, Q-LINK 3, Q-LINK 4 Ports
These are Q-Link ports. The sockets are a standard BNC coaxial type. Q-Link is a unique network that
interconnects Evertz/Quartz routers and remote control panels. It uses a standard 75ohm video cable
that daisy-chains from frame-to-frame and panel-to-panel. A ‘T-piece’ connector allows any control
panel to be removed from the network without disruption.
2.4.3. Serial 1, Serial 2, Serial 3, Serial 4 RS-422/RS-232 Ports
These are RS-422/RS-232 serial ports and are fitted as standard. The sockets are RJ-45 connections.
"
Note: Q-LINK 3 and Serial 3 share the same communications lines so only one of
the two ports can be used at any one time.
"
Note: Q-LINK 4 and Serial 4 share the same communications lines so only one of
the two ports can be used at any one time.
2.4.4. Alarm Connection
This connection is used to provide an alarm if there is a complete power failure of the unit. This is an
RJ45 connection.
2.4.5. Ethernet Connection
This is a standard RJ-45 Ethernet connection. The socket is an RJ-45 type. The port is compatible with
a 10BaseT network running TCP/IP protocol.

SC-500E System Controller
Page 8 Revision 1.0
2.4.5.1. Connecting to an Ethernet Network
The SC-500E uses 10Base-T (10 Mbps), 100Base-TX (100 Mbps) or Gigabit (1Gbps) twisted pair
Ethernet cabling systems. When connecting for 10Base-T systems, category 3, 4, or 5 UTP cable as
well as EIA/TIA – 568 100ΩSTP cable may be used. When connecting for 100Base-TX systems,
category 5 UTP cable is required. The cable must be “straight-through” with a RJ-45 connector at each
end. Establish the network connection by plugging one end of the cable into the RJ-45 receptacle of
the SC-500E and the other end into a port of the supporting hub.
The straight-through RJ-45 cable can be purchased or can be constructed using the pin-out
information in Table 2-1. A colour coded wiring table is provided in Table 2-1 for the current RJ-45
standards (AT&T 258A or EIA/TIA 258B colour coding shown). Also refer to the notes following the
table for additional wiring guide information.

8 N/A Brown/White or Brown Brown/White or Brown Not used (required)
Table 2-1: Standard RJ-45 Wiring Colour Codes
Note the following cabling information for this wiring guide:
•Only two pairs of wires are used in the 8-pin RJ-45 connector to carry Ethernet signals.
•Even though pins 4, 5, 7 and 8 are not used, it is mandatory that they be present in the cable.
•10BaseT and 100BaseTX use the same pins (a crossover cable made for one will also work with
the other).
•Pairs may be solid colours and not have a stripe.
•Category 5 cable must use Category 5 rated connectors.
The maximum cable run between the router and the supporting hub is 300 ft (90 m). The maximum
combined cable run between any two end points (i.e. router and PC/laptop via network hub) is 675 feet
(205 m).
Devices on the Ethernet network continually monitor the receive data path for activity as a means of
checking that the link is working correctly. When the network is idle, the devices also send a link test
signal to one another to verify link integrity.

SC-500E System Controller
Revision 1.0 Page 9
2.5. OPTIONAL CUSTOMIZED CONFIGURATIONS
2.5.1. Power 2 PSU 12 VDC Input
This is the redundant power supply input. The power supply can be supplied as an option. Use only the
approved power supply unit QT-PS. The part number for this unit is PSU-S-105. The use of non-
approved power supply units might have unpredictable results and may cause damage.
2.5.2. Serial 5, 6, 7 RS-422/RS-232
These are standard RS-422/RS-232 ports and the socket is an RJ-45. These ports are currently
unsupported.
2.6. ABOUT Q-LINK
Quartz routers use a communication system called Q-Link that allows routers and panels to be
connected together using a single coaxial video cable.
As standard, routers and panels have one Q-Link port for connection to other Quartz products. They
also have one or two optional serial (RS-422/RS-232) ports for connection to third party equipment.
The daisy chained Q-Link system is simple to install and has a connection limit of 64 devices. Each unit
being connected to the Q-Link has its own address switch, which is set up as part of the system
configuration. The maximum cable length is 500m.
Each end of the link must be terminated in 75.
WARNING: The installer must fit a 75Ωterminator at each end of the cable.
This daisy-chain method ensures the best transmission quality of the control signals down the cable.
Shortcuts that might save cable, such as running stubs to some panels, are not recommended as this
may under certain circumstances cause data errors.
