Federal Communications Commission (FCC Statement)
This device complies with part 15 of the FCC R ules. Operation is subject to the following two conditions: (1) This device may not cause
harmful interference , and (2) this device must a ccept any interference that may cause undesired operation.
This equipment has been tested and found to c omply w ith the limits for a class A digital device, pursuant to Part 15 of the FCC rules.
These limits are designed to provide reasonable protection aga inst harm ful interference when the equipm ent is operated in a comm ercial
environment. This eq uipment generates, uses, and can radiate radio frequency energy and, if not installed and used in accordance with
the instruction manual, may cause harmful interference to radio communications. Operation of this equipment in a residential area may

Guaran tee and Compensation
Barco provides a guarantee relating to perfect man ufacturing as part of the legally stipulated terms of guarantee. On re ceipt, the purchaser
must immediately inspect all delivered goods for dam age incurred during transport, as well as for material and manufacturing faults Barc o
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 c omm issioning,
at latest 30 days after the transfer of risks. In the event of justified notice of com plaint, Barco can repair the fault or p rovide a replacement
at its own discretion within an appropriate period. If this measure proves to be impos sible or unsuccessful, the purchaser can demand a
reduction in the purchase price or cancellation of the contract. All o ther claims, in particular those relating to compensation for direct or
indirect damage, and also damage attributed to the operation of s oftware as well as to other services provided by Barco, being a component
of the system or independent service, will be deemed invalid provided the dam age is n ot pro ven to be attributed to the absence of properties
guaranteed in writing or due to the intent or gross negligence or p art of Barco.
If the pur chaser or a third party carries out modifications or repairs on goods delivered by Barco, or if the goods are ha ndled incorrectly,
in particular if t he systems are commissioned 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 a re
system failures which are attributed to programs or special electronic c ircuitry 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 a
s the servicing and m ainten ance reg ulations specified in the this manual must be com plied with by
the customer.

1.1 Safety g uidelines
Installation personnel
This installation must be performed by authorized and qualified technical personnel only.
Accredited safety officers must ensure the safety o f the site, construction, assembly, connection, use, dismantling, transport etc. of
such safety critical systems.
Caution
Installation should be performed on ly after you are thoroughly familiar with all of the proper safety checks and installation instructions.
To do otherwise increases the risk of hazards and injury to the user.
Assembly parts are designed for intended us e only in conjunction with Barco LED-walls.
Do not m odify and/or replicate any component. B arco uses specific materials and m anufacturing processes in order to achieve part
strength. Consult Barco for assistance with custom applications.
Always follow B arco installation instructions. C ontact B arco if you should have any question re garding the safety of an application.
The manufacturer assumes no liability for incorrect, inadequate, irresponsible or unsafe assembly of
system s.
Product care
Structural & mounting c ompo nents s hould be kept clean, lubricated (only if recommend ed), coated properly, and otherwise main-
tained in a manner consistent with part design. Barco products must be used in a manner consistent with their design and inspected
on a routine basis for security, wear, deformation, corrosion and any other circumstances that may affect the load handling capab ility
of the part.
Barco recommends inspections at regular intervals for a ll installations and increasing in frequency for more critical installations. If
a part is found to have damage, w hich may cause a decreas e in load capability, the part must be removed for service or replaced
immediately.
Under no circums tances are Barco parts repairable by anyone other than B arco.

2.1 General functionality
Introduction
The Ambient Env ironment Controller (AEC ) is a device containing four light senso rs. These sensors are used to measure the ambient
environment luminance. The control of the AEC is integrated into the software of the Control Software (E.g. RMS-1). T he A EC-4000
has been specially developed to be integrated in to a DB -x20 or SLite LED-wall display. The AE C-4000 may b e incorporated to a
Barco LED-wall, measuring the environmental light conditions through out the day. The modular concept of the AEC-4000 gives
rise to con fi gurations with maximum flexibility and controllability. The built-in intelligence of the control s oftware allows the system to
detect and configure itself. The mechan ical flexibility and s mall form enables easy installation a nd quick servicing. AE C-4000 units
are only to be used in conjunc tion with a Barco LED-wall. The Control Software (E.g. RMS -1) has an intelligence control algorithm
depending on which the brightness of LED wall is calculated according to the luminance input from A EC-4000

The Y cable used to c onnect AEC-4000 with other tiles has two paths. One path transmits DV I video signal. T his path doesn’t enter
the AEC-4000 and directly goes to the next tile. The second path transmits the command signal (RS422) and power supp ly for the
AEC-4000. The signal in this path will enter the AE C-4000 and then transfer to the next tile (only RS422).
