Installation Guidelines 3 INSTALLATION GUIDELINES Installation guidelines Careful consideration of things such as image size, ambient light level, projector placement and type of screen to use are critical to the optimum use of the projection system. * Environment Do not install the projection system in a site near heat sources such as radiators or air ducts, or in a place subject to direct sunlight, excessive dust or humidity.
Installation Guidelines * What Image Size? Where to Install the Projector? The projector is designed for projecting an image with an aspect ratio of 4 to 3. Screen sizes : min : 2.4 m x 1.8 m (7.9" x 5.9") max : 7.0 m x 5.25 m (23" x 17.3") The distance between projector and screen (= projection distance) depends on the screen width and the projection angle. Due to all of these dependencies, it is recommended to use the BARCO Lens Program to calculate the projection distance.
Installation Set Up 4 INSTALLATION SET UP Connecting Optical Block and Electronic Block together In order for the projector to work, the following parts must be connected to each other: è ç Electronic block (image1) ç è Cable tube (image 2) Optical block (image 3) To gain access to the connectors of the electronic block, follow the procedure as described below : 1. Loosen both indicated screws (image 1). 2. Take off the protection cover.
Installation Set Up Connecting the cable tube to both blocks. The cable tube contains 9 cables which have a connector at each end of the cable tube. The following cables can be distinguished: RED - GREEN - BLUE (75 Ω cable) Focus RED - Focus GREEN - Focus BLUE (20 kV cable) EHT (50 kV cable) Signal cable A Signal cable B (both cables have a male 36 pin connector.
Installation Set Up Connecting signal and data cables to the optical block. Plug the R-G-B cable with BNC plug into the BNC connector in the optical block. The cables and the connectors are marked with the respective colors. Plug the 36 pin plug with the white wires into connector J1. Plug the 36 pin plug with the green wires into connector J2. Plug the 24 pins plug with the gray wires into connector J3. Interchanging of the two connectors with 36 pins is prevent by a build-in key in the female connectors.
Installation Set Up Note: It is possible to change the interance of the cable tube in the electronic block. There is an opening to mount the cable tube in at each side of the block. The unused opening is closed with a protection plate. To change the interance, remove on both sides the plates with the indicated screws and remount them in the opposite way. Scan Adaptation The scanning can be switched by changing the position of the scan switches of the Horizontal and Vertical deflection.
Installation Set Up 2. Remove the Horizontal Deflection module to access the horizontal scan switches. 3. Loosen the securing screws of the Hor. Amplitude coils and pivot the module. The switches are accessible. 4. Remove the Vertical Deflection module to access the vertical scan switch. Horizontal Deflection Vertical Deflection module module Horizontal Deflection Coils Vertical scan switch Connectors for the vertical deflection module To remove a module, follow the next procedure : 1.
Installation Set Up Position of the scan switches for the different mounting configurations are illustrated on in next drawing. +RUL]RQWDO 9HUWLFDO VFDQ VFDQ VZLWFKHV VZLWFK After setting the scan switches, re-insert all modules and close all covers. Reconnect the power cord to the wall outlet. Note : Switching over from floor to Ceiling or vice versa requires a complete re-adjustment of picture geometry and convergence.
Projector set-up 5 PROJECTOR SET-UP The DIP switches on the controller board allow the SET-UP of the projector : ρ 8 DIP switches for setting the projector address. r 1 DIP switch for setting the power up mode. r 3 DIP switches for setting the baud rate for communication. r 1 DIP switch for setting the password mode. To gain access to the DIP switches : - Open the top cover of the electronic block (see chapter Installation setup).
Projector set-up Setting the address is a hardware SET-UP of your projector which must be done during installation. Use the 8 DIP switches provided on the controller board labelled 'Projector Address'. Each DIP switch has its own decimal value. The sum of the values associated to those DIP switches gives the address. As shown in the table, if Switch No. 1 is set to ON, it represents a decimal value of 128, Switch No.2 for 64, Switch No.3 for 32, and so forth.
Projector set-up Baud Rate for communication with a computer The communication speed between the projector and the computer has 8 possible settings. With DIP Switch No. 6, No.7 and No.8 of the 8 DIP switches on the controller board, labelled as Baud rate code (sum), it is possible to select the baud rate (communication speed). Each DIP switch has its own decimal value. The sum of the values associated to those DIP switches gives the baud rate code. Each baud rate code corresponds an communication speed.

Power Connection 6 POWER CONNECTION Power (mains) cord connection Use the supplied power cord to connect your projector to the wall outlet. Plug the female power connector into the male connector at the front of the projector. PROJECTOR MODE PORT 1 PORT 2 PORT 3 PO RT 4/5 7 KL V GHYL FH F R PS O LHV Z LWK S D UW R I COMM.
Power Connection Input power (mains) voltage adaptation. Attention The BARCOREALITY 812HS - R9002260 leaves the factory to operate on a mains (power) input of 230 Vac. The BARCOREALITY 812HS - R9002239 leaves the factory to operate on a mains (power) input of 120 Vac. Adaptation of the power input of the projector from 230 VAC to 120 VAC or vice versa is possible. Follow the procedure as described below. Procedure - Unplug the power cord from the power input on the front panel.
Power Connection - Pull out the 'power selector plug' and reinsert as illustrated, depending on the wall outlet in the room. - Reinsert the module. - Re-insert the module and secure with both screws. 120V 230V Power selector on 230V Fuses AC power Warning ! For continued protection against fire hazard : Fuses Power selector on 120V Order Number 230 Vac T6.3A/250V (2x) R314145 120 Vac T10A/250V (2x) R314154 Replace with the same type of fuse.
Power Connection Starting up with a full white image When the projector is set to start up with a full white image, the "Projector warm up" menu will be displayed for 30 seconds. PROJECTOR WARM UP A FULL WHITE PATTERN WILL BE GENERATED FOR 20 MINUTES. FOR IMMEDIATE USE OF THE PROJECTOR, PRESS . Start up with "Warm up period" If no action is taken, a white image will be displayed for 20 minutes. This white image will be shifted on the faceplate of the CRT to avoid CRT burn-in.
Installation adjustment mode 8 INSTALLATION ADJUSTMENT MODE Access to Installation Adjustment Mode It will be necessary to perform several mechanical adjustments while in the Installation Adjustment Mode. It will be required to open and remove the projector's top cover in order to gain access to the adjustment points.
Installation adjustment mode Important : Access to adjustments The top cover of the projector should be removed in order to gain access to the adjustments. Please refer to p.4-1 for how to remove the top cover. Projector Distance On the screen, a drawing will be displayed together with parameters indicating a correct installation position.
Installation adjustment mode Raster Centering The raster must be centered on the CRT faceplate of each tube, therefore, it is necessary to look into the lenses. 5$67(5 &(17(5,1* Caution : To avoid eye discomfort while performing these adjustments, reduce the contrast and gradually increase the brightness level until the raster becomes visible behind the image. Warning : In order to ensure maximum CRT longevity and to avoid CRT damage, do not shift the raster outside the phosphor area of the CRT.
Installation adjustment mode CRT Projection Angle Adjustment The projection angle of the red and blue CRT's is dependent on the desired size of the projected image. If the centers of green, blue and red do not coincide, the CRT projection angle must be adjusted. NOTE : Never try to correct this misalignment with the shift correction or the static convergence controls. These controls may only be applied to correct small errors which cannot be corrected by the CRT angle adjustment.
Installation adjustment mode Loosen bolts E, F, G and H to pivot the blue CRT until the center of the Blue image and the center of the Green image coincide. When the angle of the blue CRT is corrected, tighten the four bolts. Press the key to continue with the diagonal focusing menu. Press the key to return to the CRT projection angle adjustment.
