Wi PLUS USER MANUAL | 3
Usage Notice
Please follow all warnings, precautions and maintenance as recommended in this
user's manual.
Warning - Do not disassemble Light Curtain Touch module.
Warning - Do not use, store, or leave Light Curtain Touch module near fire, or
in places with a high temperature, e.g., in direct sunlight, or in sun-heated cars.
Warning - Use standard USB cable(maximum length: 5m). To extend USB cable
length over 5m, a certified active extension USB cable is required.
Warning - Do not allow liquid or foreign material enter Light Curtain Touch
module.
Precautions
IR camera on projector receives infrared signal from Light Curtain Touch module
which is attached to the whiteboard.
To operate normally:
IR camera should face the projection image area on the wall.
Remove any obstacle in between IR camera and Light Curtain Touch module.
Do not place other infrared communication devices, lighting equipments, or
residential heating equipments etc, nearby.
Only use the interactive cable from accessory kit, L side connector should plug
into Light Curtain Touch module.
Maintenance: Gently clean the optical port with dust blower.
How it works
Light Curtain Touch covers the entire whiteboard with a thin invisible IR light.
When finger or stylus breaks into the Light Curtain Touch, IR light reflects to IR
camera.
Camera module tracks multiple touch points and reports positions to a PC or
laptop via USB.
To optimize touch function, whiteboard non-flatness should be less than 5mm.

Step 1: Environment Check
Before setting up and installing the projector and Light Curtain Touch module, ensure
that the interactive cable work for the installation location of the mount in advance.
Note:
Make sure the projector is installed under the following conditions:
- The projected image is a rectangular shape without any distortion.
- The projector is tilted at an angle no more than +/-3 degrees vertically and horizontal
in relation to the screen.
- When using the interactive function, install the projected image within reach.
- Do no install the projector or screen in a location subject to direct sunlight. If the
projector or the screen is subject to direct sunlight, the interactive function may not
operate correctly.
A. Light Curtain Touch installation Information
Before installing the Light Curtain Touch module, the projection surface must meet
the following conditions/criteria:
1. The screen surface is a flat, smooth unwrapped surface with no unevenness of
more than 5mm. The surface can either be a flat wall or a whiteboard. For
details on how to check surface flatness see page 8.
2. The surface must allow for the Light Curtain Touch module to be fixed with
screws.
If the projection surface meets the criteria above the projector and Light Curtain
Touch module can then be installed in one of the following ways
1. Mount the projector to the wall and the Light Curtain Touch module to the
whiteboard.
2. Mount the projector and Light Curtain Touch module to the wall.

Wi PLUS USER MANUAL | 5
B. Whiteboard guideline
When installing the Light Curtain Touch module on a whiteboard please follow the
guidelines below:
B-1. For standard aspect ratio (4:3, 16:10 and 16:9)
B-2. For ultra-wide aspect ratio (16:6)
If the whiteboard frame thickness is greater than 3mm the reflected light interference
from the whiteboard frame may be detected by IR camera. This can compromise the
touch function. To reduce the risk of this happening it is recommend that a 50mm
boarder is kept around the projected image instead of 10mm as shown in diagram on
the previous page.
For standard aspect ratio (4:3, 16:10 and 16:9)
gap: 2~10cm
From the top of image area, a gap must be kept 2~10cm
away from the bottom of LCT module.
For suggested whiteboard frame design(height <3mm),
keep 10mm bezel at left/right/bottom of image area.
For regular whiteboard (ex: aluminum frame,
height>3mm), keep 50mm bezel at left/right/bottom of
image area.
For ultra-wide aspect ratio (16:6)
gap: 4~10cm
From the top of image area, a gap must be kept 4~10cm
away from the bottom of LCT module.
For suggested whiteboard frame design(height <3mm),
keep 10mm bezel at left/right/bottom of image area.
For regular whiteboard (ex: aluminum frame,
height>3mm), keep 50mm bezel at left/right/bottom of
image area.

If the whiteboard frame thickness is less than 3mm, ensure the reflected light
interference is not observed while doing Step 6 Laser Beam Alignment.
C. Measuring projection surface flatness
Criteria: overall whiteboard flatness <5mm, flatness requirement is <3mm at Light
Curtain Touch module mounting area.
Equipment: leveling instrument (1.2~1.5m) and thickness gauge.
Split projection area into 16 segments equally as below chart. Place leveling
instrument on whiteboard.

Step 2: Installing the Light Curtain Touch
module
1. Open top cover by screwdriver.
2. Mount base plate to whiteboard or wall
Keep away distance to image area for ultra-wide aspect ratio (16:6):
-7.5 ~ 13.5cm from bottom of base plate
-4 ~ 10cm from bottom of Light Curtain Touch module
Keep away distance to image area for standard aspect ratio (4:3, 16:10 and 16:9):
-5.5 ~ 13.5cm from bottom of base plate
-2 ~ 10cm from bottom of Light Curtain Touch module
2-1. For short-term demonstration:
2-1-1. Clean surface with isopropyl rubbing alcohol, wipe gently, let dry.
2-1-2. Adhere double-sided tape (enclosed in accessory box) onto base plate, then
paste onto the whiteboard or wall.
Caution: Do not use with wallpaper. May not adhere well to vinyl surfaces or

textured surfaces.
2-b. For long-term use:
Use screws to fix base plate onto whiteboard:
-Drill tip: ΦO=2.3mm
-Screw type: M3x6L
-Screw head: ΦO<5.5mm, thickness <2.5mm
3. Fix curtain module with wall plate by screws
4. Plug power cord to Light Curtain Touch module
Note: L side connector must plug into Light Curtain Touch module.

B-1. After the camera captures the projection image, a Touch Area window will pop
up. If the captured image is not clear enough, please re-select “Ambient light
mode selection” from “Auto” to “Bright” or “Dim” according to actual ambient
light condition.
Remark: Captured image shows the actual camera view, which is reversed from
projection image. For example: P1 is lower right corner, P2 is lower left corner
and so on.
B-2. Touch Area Boundary Fine-tuning
Step 1: Click on P1, use mouse to drag P1 to upper left corner. Align
adjustable green zone with projected white frame.
Step 2: Adjust P2 to P4 accordingly; adjustable green zone should
completely overlaps the projected white frame.
Step 3: Finally, check again if the green frame completely overlaps the
projected white frame. If not, fine-adjust again.
B-3. When the Touch Area is correctly located click to exit.

Step 8: Calibration
A. Select Auto Calibration
If the fail message pops up, follow below steps to trouble-shoot and do Auto
Calibration again.
Close all software application
Reduce ambient light
Do not obstruct or shake lens during calibration
Check if projection image is clear. If not, adjust focus to sharpen the image
If the Auto Calibration fail message still pops up on screen, switch to Manual
Calibration.

Step 10: Trouble-shooting Viewer
Sometimes infrared red light (IR light) from ambient light sources may interfere with
touch performance. The troubleshooting viewer shows real time images for debugging
purposes. Any light interference is marked in green. If green obstacles appear within
image area, remove to secure proper interactivity.
Note: Interactive function is disabled under trouble-shooting viewer, click to exit.
