Introduction Components Technology Barco Wall Control Manager

OV-7xx

OV-5xx

Wall naming convention

OVf-SRR OV= overview S = screen size

– 5 = 50 inch– 7 = 70 inch– 8 = 80 inch– 10 = 100 inch

RR = resolution – 08 = XGA = 1024x768 = 786 000 ~ 8– 13 = SXGA = 1280x1024 = 1 310 720 ~13– 15 = SXGA+ = 1400x1050 = 1 470 000 ~15

f = front accessible

Examples : OV-508 OV-715 OV-1013

Screens

Rear projection screen requirements Viewable from all angles High contrast Focused Minimal reflection

Cleaning of screens : Avoid to touch screens !!!! See user manual for cleaning instructions.

Screens

Screens can be mounted in different ways. Expand/shrink due to temperature and moisture Canned

– Minimal gap between screens– Visible gap– Only 50” and front access 70 “

Canned – seamless– No gap– Screens push against each other– Only 50”

Stitched– Small needle like wires hold the screens together– No gaps– Only from 70” onwards

Components : Projection Unit

Projector Alignment

Correct geometry on the screen by tilting the projector in its frame

Service personnel only !

Components : Illumination unit

Components : Dual Lamp system

•120W/132W lamp•two lamps in each projector•Switch automatically upon failure•Lamp lift mechanism

Components : Intelligent Lamps

Mounting handle and locking mechanism

120W/132W lamp

Lamp ID chipAir inlet for burner cooling

power

Lamp cut-off voltage – lamp retry

When lamps get older they can Simply stop working and refuse to start again Explode…… : no danger !

Graph not representative, for illustration purposes only !

Maintenance actions

- Defective lamp :- Retry lamp first (reset error + reselect lamp)- When fails again (same day)- Replace lamp- Lamp warm-up – wait 2 min.- Optimize the new lamp! (only possible in service mode).

Air Filter Replacement- Dependent on Contract and/or Need- Don’t shake the dirty filter- Dispose used filters – DO NOT CLEAN

Components : Typical delays & button functions

Cooling / warming : 2 min Color stabilizing : 5 min Overtemp before shutdown : 5 min

On/Res button: Up

– 1-3 sec: switch on from standby– 4-8 sec: toggle between IP address and error status– > 10 sec: reset lamp error

Down – 1-3 sec: switch to standby– 4-8 sec: not used (yet)– >10 sec: self diagnostic of IU

Technology

What’s inside the projector units ?

Technology : DLP chip

DLP-chip technology– One chip containing more than 1m mirrors– Each mirror representing one pixel– Pixel value is created through reflection time modulation– See movie...

Light-path

Technology : PU - Color sensor

Allows the BCM software (see further) to Have equal brightness on every projector Have equal color on every projector.

Barco Wall Control manager (BCM)

Controlling all your walls from an easy to use software

Network Interfacing: Wall Control Network

BCM for administrators – simple view

Features Overview of cubes Shows health Multiple walls Can generate reports

BCM for administrators – lamp view

BCM for administrators – input view

BCM: Brightness Lock

3 basic modes: Uncalibrated

– Brightness locking not active so dimmer wheel stays in last known position.

– Color correction not active so native colors are shown.

Brightness locked– The brightness is dynamically controlled with the dimmer

wheel by using only the brightness information of the color sensor. The colors are static.

Sense 6 (License required, see BLM)– Next to Brightness, color is also dynamically controlled. This

is done with the DMD chip.

BCM for administrators

Problems or alarms Severity :

– Green– Yellow– Orange– Red

Recommended solution

BCM: License

Following options will require licenses:– Hot standby– Sense6– High power (120 -> 132 W)– Scaling

Checking for the required licenses:– Via BCM, Help menu
