Guarantee and compensation
Barco provides a guarantee relating to perfect manufacturing as part of the legally stipulated terms of guarantee.
On receipt, the purchaser must immediately inspect all delivered goods for damage incurred during transport, as
well as for material and manufacturing faults. Barco must be informed immediately in writing of any complaints.
The period of guarantee begins on the date of transfer of risks, in the case of special systems and software on
the date of commissioning, at the latest 30 days after the transfer of risks. In the event of justified notice of
complaint, Barco can repair the fault or provide a replacement at its own discretion within an appropriate period.
If this measure proves to be impossible or unsuccessful, the purchaser can demand a reduction in the purchase
price or cancellation of the contract (redhibition). All other claims, in particular those relating to compensation for
direct or indirect damage, and also damage attributed to the operation of software as well as to other services
provided by Barco, being a component of the system or independent services, will be deemed invalid provided
the damage is not proven to be attributed to the absence of properties guaranteed in writing or due to the intent
or gross negligence on the part of Barco.
If the purchaser or a third party carries out modifications or repairs on good delivered by Barco, or if the goods
are handled incorrectly, in particular if the systems are commissioned or operated incorrectly or if, after the
transfer of risks, the goods are subject to influences not agreed upon in the contract, all guarantee claims of the
purchaser will be rendered invalid. Not included in the guarantee coverage are system failures which are attrib-
uted to programs or special electronic circuitry provided by the purchaser, e. g. interfaces. Normal wear as well
as normal maintenance are not subject to the guarantee provided by Barco either.
The environmental conditions as well as the servicing and maintenance regulations specified in this manual must
be complied with by the customer.

2.1 Properties
ARGUS was designed to control large, modular OVERVIEW display walls. Its multi-screen capability allows you to
control displays of virtually unlimited size. The display area is one logically connected display. Digital imaging
devices based on modern technologies such as Single LCD, DLP and Poly-Silicon LCD with the highest display
quality are controlled digitally. Digital data transfer is immune to electromagnetic interference and therefore
ensures the display wall picture to be displayed in absolutely distortion free image quality. ™
CRT monitors and analog projectors can also be controlled by ARGUS, using the analog output mode of the graphic
cards. Thus, multi-monitor operator stations can be ergonomically designed and easily implemented.
(DLP is a trademark of Texas Instruments Incorporated)
The hardware and software of ARGUS is based on world-wide accepted standards. ARGUS offers the following ex-
ceptional capabilities:
•High performance graphics output using the most modern processor and chip technologies
•Supports current LAN and WAN interfaces
•Graphic and video outputs in high color quality
•Video in a window, up and down scaleable up to full-screen
•Overlapping and freely moveable video and graphics windows of unlimited size
•Up to 4 videos on one to four projection modules.
The ARGUS system provides a flexible and scalable architecture, which is suitable to support all sizes of display
walls. Just one ARGUS PROCESSOR and one to five ARGUS OMNIBUS devices can be used to set up a monolithic system.
Or for more complex configurations a distributed system can be used consisting of a central processor and multi-
ple rendering engines to control a display wall of any size and number of input sources.
Independent of the usage of a monolithic system or a distributed system, both the user and the application soft-
ware ‘see’ one single display. Installation, operation and service do not differ from that of a standard X terminal.
ARGUS offers the possibility to operate it in normal boot mode or in eXtended safety boot mode. Normal boot
mode offers full write access to the hard disk and enables the operation of the wall management software OSIRIS.
eXtended safety boot mode offers in addition to normal boot mode a backup partition for improved system
safety. With eXtended safety boot mode the system files are stored safely, and faultless startup is guaranteed
even after unpredictable events, e.g. power failure.
ARGUS is the perfect solution for the integration of video and RGB sources into desktop graphic data into digitally
controlled display walls. However graphics only systems support also analog display connection.

Argus - monolithic system
A monolithic system consists of an ARGUS PROCESSOR that connects to up to five ARGUS OMNIBUS devices. The PROCES-
SOR is the host computer of the OMNIBUS. A monolithic system allows to control up to 72 projection modules with
the ability to display video and RGB windows on the whole wall or even larger display walls that display video
and RGB only on parts of the wall.

Argus - distributed system
In a distributed system one ARGUS PROCESSOR is used as central processor. It is equipped with keyboard and mouse.
Via a sub-net the central processor controls the rendering machines. Each rendering machine consists in an ARGUS
PROCESSOR used as rendering processor and one or two ARGUS OMNIBUS devices. The rendering processor is the host
computer of its one or two OMNIBUS devices.
The processors distribute and process the graphic data of the X server, whereas the OMNIBUS devices are
equipped with the Barco graphic cards, OMNISCALERS and input cards to integrate video and RGB data and to dis-
play it on the display wall.
The distributed system enables to set up display walls of any size where video and RGB windows can freely be
moved.
