1. System Introduction
The Espedeo™ PM-2000A is a standalone passive 3D Polarized System specially developed for digital
cinema projectors. Featuring flexible and easy installation, the system can automatically switch to the
corresponding operating position by identifying 2D and 3D signals. Equipped with specified polarized
glasses, the PM-2000A is able to present stunning and brilliant 3D images.
1.1.Key Features
▪Easy Installation
The system can be installed right in front of digital cinema projector by simply using the bracket
delivered along with the system itself.
▪Simple Connection
The entire system is simply connected by two connection cables with the digital cinema projector
and motorized bracket.
▪2D-3D Switching
The polarizer automatically identifies 2D/3D signals. It automatically moves to the front of the lens
while playing 3D images and automatically moves to the standby position when playing 2D images
or system is idle.
▪Easy Maintenance
The polarizer can be cleaned and maintained in an easy and fast manner. In addition, the polarized
glasses can be directly replaced if there are any damages of the polarized glass that affect
projection quality.

4.3.Motorized Bracket
Figure 4: Motorized Bracket
▪The motorized bracket is a passive 3D system apparatus for automatic switching between
3D/2D playing.
▪Installed on top of the bracket support base, the motorized bracket connects to the polarizer
through the DB9M/9F motor signal cable. When the digital cinema projector is playing 3D movie,
the polarizer automatically moves upward to the front of the lens to polarize light paths. When
the digital cinema projector is playing 2D movie, the polarizer automatically moves downward
from the front of the lens.
▪The motorized bracket works with the adjustable bracket extension kit to adjust the position of
the polarizer.
4.4.Bracket Support Base
Figure 5: Bracket Support Base
The bracket support base is placed in front of the digital cinema projector which is used to fix the
position of motorized bracket. The height of the legs can be adjusted to fit various installations.
Moreover, two sets of screw holes are used to fix the bracket for the alternative, as shown in Figure 5.
NOTE
Please ensure that the distance between projector lens and the polarizer is within 15cm after the installation.

5.5.LED indicators of Passive 3D System
Figure 11: LED Indicators on the Polarizer
POWER (Power LED):
Turn ON the power switch of the polarizer for power supply.
oIf the power LED is ON in green color; it indicates that the power supply has been connected.
oIf the power LED is OFF; check whether the signal cables are properly connected and whether the
digital cinema projector has been powered on.
SYNC (Synchronization signal LED):
oIf the Sync LED is ON in green color; it indicates that 3D signals are detected and a 3D movie can be
normally played.
oIf the Sync LED is OFF; it indicates that no 3D signals are detected. In this case, check whether the
synchronization cable is properly connected and whether the digital cinema projector is properly set.
L/R (Left/Right eye switching signal LED):
In case the audiences feel the depth of field is inverted inside 3D image objects; for example, which
makes the background seem to be in the front and front objects are at the back, this is because the light
phase of polarizer and 3D glass is inverted. Then we can press the L/R switch to toggle the Left/Right
eye signal for correction.

5.6.Adjusting the operating position of the Polarizer for 3D Playback
During a 3D movie playback, the polarizer automatically moves to the default/pre-set operating
position. The 3D operating position of the polarizer can be achieved by choosing aluminum rods of
suitable lengths and adjusting the height of the rod, as shown in Figure 12.

5.7. Adjusting the default 3D operating position of the Motorized
Bracket (When adjustments mentioned in Section 5.6 cannot be performed)
When the aluminum rods fail to enable the polarizer to be aligned to an appropriate operating position,
you would need to set the default 3D operating position of the motorized bracket, as shown in Figure 13.
Step ①: Turn OFF the power switch on the polarizer.
Step ②: Manually raise the clamping block of the motorized bracket to a height of about 300 mm from
the bracket support base, and then adjust the 3D operating position of the polarizer (so that the light
path projected out of the digital cinema projector from the lens can be completely reflected on the
polarizer and falls in its center).
Step ③: Hold the setting button and turn ON the power switch. Do not release the setting button until
the power LED is ON and the synchronization signal LED and left/right eye switching LED starts flashing.
Step ④: After the above setting is completed, the polarizer automatically moves back to the standby
position and then moves to the designated 3D operating position. Restart the system to complete the
setting operation.
If the position of 3D projection is not accurate after adjusting, you may need to adjust the aluminum
rods by loosening the screws on the clamping block to fine tune the position.
To confirm whether the installation positions are appropriate, perform the following checks:
▪During 3D movie playback, the light path projected out of the digital cinema projector just falls
within the polarizer glass frame.
▪During 2D movie playback, the passive 3D system does not block the light path projected out of the
digital cinema projector.
▪The motorized polarizer stays apart from the digital cinema projector by moving downward when
transit from 3D to 2D mode.

6. Optical Alignment
Load the cross-calibration pattern of the digital cinema projector and slightly adjust the top, bottom, left,
and right positions of the polarizer, so that the projected light path coincides with the cross-calibration
pattern on the projection screen.
Figure 14: Adjusting the Calibration Pattern
▪Loosen the lock screen screw on the back of hinge as indicated in Figure 14 (refer to Step ①), prior to
making any adjustments
▪Loosen screw A to turn the polarizer to adjust the top and bottom positions of the cross- calibration
pattern, note to
▪Turn the bracket support base to adjust the left and right positions of the cross-calibration pattern.
▪If the tilt level is out of above range, try to adjust the height of the legs to level the system with
reference of level meter that locate on top of polarizer during the adjustment.
▪Tighten the lock screen screw on the back of hinge, after the adjustments have been made.
