PM-2000B 3D Polarized System Installation Manual
1. System Introduction
The Espedeo PM-2000B is a standalone 3D polarized system specially developed for Espedeo digital
cinema projectors. The PM-2000B is designed for easy installation and operation by detecting 2D and 3D
signals, which enables the system to shift corresponding working positions automatically. The PM-2000B
is suitable for Espedeo Supra-5000 Digital Cinema and Secured Media Projection System in any
orientation; whether fixed on a pedestal or hung on a ceiling. Combined with Espedeo passive 3D
glasses, you’ll experience vivid and lifelike 3D imagery with bright accurate colors.
NOTE
The PM-2000B 3D System is compatible with the Supra-5000 projector only.
1.1 Key Features
▪Simple Installation
It can be installed in front of the client's digital projector with its own bracket.
▪Easy Connection
The connection is simple with only two cables required between the 3D system and
digital cinema projector.
▪2D-3D Conversion
Espedeo PM-2000B’s liquid crystal splitter can identify 2D / 3D signals and change its positions
accordingly with a motorized bracket. When playing a 3D movie, the liquid crystal splitter will
move in front of the lens automatically. When playing a 2D movie or there is no movie, the liquid
crystal splitter will move back automatically to its standby position.
▪Convenient Maintenance
The liquid crystal splitter can be cleaned effortlessly. Also, the polarized 3D glasses are
replaceable if damaged.

4.1 Liquid Crystal Splitter
Figure 1: Liquid Crystal Splitter
The liquid crystal splitter is the main optical element part of PM-2000B system with an overall
dimension of about 163*128*16mm, which should be handled with care during installation.
4.2 Height Adjustment Bracket
Figure 2: Height Adjustment Bracket
The height adjustment bracket is used to connect the liquid crystal splitter and the electric bracket
and its height can be adjusted to work with the projector.

4.3 Electric Bracket
Figure 3: Electric Bracket
The electric bracket is a device for the passive 3D system to automatically switch 2D/3D.
Installed on the mounting bracket, the electric bracket is connected with the liquid crystal splitter
by the motor drive signal line; when the digital projector plays a 3D content, the liquid crystal
splitter automatically moves to the front of the lens to modulate the light. When the digital
projector plays a 2D content, the liquid crystal splitter automatically moves away from the
front of the lens.
With the height adjustment bracket included in the accessories, the position of the liquid crystal
splitter can be adjusted.

Wiring of synchronous signal line:
The 15-pin end of the synchronous signal line is connected to the synchronous signal output
interface on the Supra-5000 DCMB and the USB end is connected to the synchronous signal
input interface of the Liquid Crystal Splitter, as shown in Figure 11.
Figure 11: Synchronous signal line wiring connections
Wiring of motor drive signal line:
One end of the motor drive signal line is connected to the motor drive signal output interface of
the Liquid Crystal Splitter and the other end is connected to the motor drive input interface on the
electric bracket, as shown in Figure 12.

Power ON and check the signal indicator. After wiring is done, start the digital projector to play 3D
content and check the signal indicator on the liquid crystal splitter.
Figure 13: Liquid Crystal Splitter Indicators
SYNC synchronization signal indicator:
When the indicator light is ON, it means that 3D signal is detected and 3D content can be shown
normally. If the indicator light is OFF, it means that no 3D signal is detected. Please check
whether the synchronous signal line is connected properly and whether the setting of digital
projector is normal.
L/R switch indicator for left and right eyes:
If the depth of field of stereo image is found to be reversed (e.g.: the background image goes to
the front and the front image goes to the back. This is because that the phase of light valve and
light source of stereo glasses are reversed), the left / right eye signal can be switched for
correction by pressing the L/R switch.

5.5 3D Working Position Adjustment of Liquid Crystal
Splitter
When a 3D content is played, the Liquid Crystal Splitter will automatically move to the default
working position. The 3D working position of the liquid crystal splitter can be set by adjusting the
height of the height bracket, as shown in Figure 15 and Figure 16.

Figure 16:
Confirm whether the installation position is appropriate by the following means:
▪When a 3D content is played, the light path from the digital projector is just in the middle of
the incident angle of the passive 3D system.
▪When a 2D content is played, the passive 3D system won’t block the light path from the
digital projector.
The liquid crystal splitter will not touch the digital projector lens in the process of moving.
