Product Value Features
* Stylish and sophisticated appearance. Looks like a tablet, and the rectangular
appearance makes it easy to change dimensions.
*Light and thin product. Cabinet weight is less than 30kg/sq.m, with only 54mm
thickness, with more than 25% reduction in weight and over 35% reduction in
thickness compared to similar products in the market.
*Brand new smart monitoring. Monitoring card not required to monitor signal
receiving cards, modules, cables, temperature etc. A breakthrough from
traditional architecture, reducing wiring and failure points.
*Supports PCs, tablets, mobile phones and other smart terminals to connect to the
display for monitoring screen operation
*Smart Modules: Module can store ID number, production date, order information,
usage duration, color coordinates, current and other information. More
convenient and practical.
*Complete front or rear maintenance. Perfect for environments where only rear
maintenance is available like window display, but also perfect for environments
where only front maintenance is allowed, such as wall mounted installation at
malls.
*Complete front installation and maintenance can be adopted for wall-mounted
installation, with magnetic modules, power supply, signal receiving card, HUB,
cable wirings, etc., accessible from the front, ensuring easy and fast servicing, and
zero-maintenance-channel requirement.
*Magnetic modules enable fast and convenient module installation and disassembly
without screws.
*Cabinets can be installed both horizontally and vertically. The module can be
rotated along with cabinets by 90 degrees for assembly (rotating the module and
cabinet together does not affect the viewing angle), ensuring the screen can be
installed vertically, to meet customers’ different installation requirements.
*Sub-frame enables faster installation.
*Fan-less design for cabinets and power supply, eliminating noise and reducing
power consumption. More energy savings.
*Uses crystal head sockets and reliable power plug sockets for signal and power
cable connections between cabinets and signal source, and power plug and
socket, for faster and safer connections.
*Easy cabinet testing and operating status monitoring with external test button and
indicators.
*High definition ensures excellent and super clear display effect. No ghost shadows
or caterpillar problems, with high grayscale, high refresh rate, and high grayscale
at low brightness, highlighting exceptional display affect.
*Super large viewing angle, high contrast ratio. Uses TOP type SMD LED, combined
with light trap mask design, ensuring excellent optical effects
*Supports Absen’s 3rd with built-in data correction memory, so that users can
directly replace modules without cumbersome setup, and can easily import and
calibrate data.

Product Components
Cabinet Introduction
Product Structure / Electronic Components Details
Product structure consists of two parts: Cabinet and module.
Cabinet have two different type：864*288mm(3 modules width) and 288*288mm
（one module width）
It can be easily combined into three kinds of cabinet size by the bolts,
864*288mm/1152* 288mm/ 1440*288mm, which can application in different case.

13
Cabinet structure: Full aluminum die-casting cabinet is extremely thin and light.
Cabinet can be installed either horizontally or vertically.
Modular structure: Magnetic modules. Relative to the cabinet structure, modules
can be rotated by 90 degrees for installation, so that the cabinet can be installed
vertically or horizontally. When installed vertically, the module needs to be rotated
by 90 degrees, so as not to affect left and right viewing angle.

Product Installation
Various installation methods are available for this product: front installation, rear
installation, floor installation,using sub-frame for fast installation, as well as wall-
mounted installation.
Front Installation
Remove the modules from left and right sides of the cabinet, use M5x60 bolt at the
front mounting holes to fix it to the steel structure. After it is fixed properly, connect
power cables and signal cables, and then put the removed modules back.
Rear Installation

17
Use M8x60 bolts and connecting plates to fix onto the 40X40 square tube bar.
When installing, first fix 4 (2 to 4) cabinets onto the sub-frame, and then mount the
sub-frame onto the steel structure or wall, to achieve fast installation.
Note: Front or rear installation can also be used for sub-frame installation.

18
Wall-mounting Solution
Install cabinets onto the sub-frame or fixed structure, and then directly mount the
sub-frame onto the wall,to achieve wall-mounting installation.
Front Installation Instructions (Wall-mounting)
Step 1:

19
Step 2:
Take a properly spliced cabinet, remove modules from four corners, mark
installation positions on the wall according to the mounting holes on the sub-frame.
Step 3:
According to the installation positions marked on the wall, install M10 expansion
screws.
Step 4:
Install the cabinet: Mount cabinets onto the wall corresponding to the M10
expansion screw positions,and then lock M10 nut (flat cushion + spring washers)
Step 5:
After wiring is completed, insert modules back at the four empty corners. Repeat the

20
same procedures to install the next spliced cabinet.
Product Wiring
Power Supply Wiring
• Preparation before wiring
Before connecting to power supply and switching on control signal to the entire
screen, please carefully check the power supply and signal cable connections. Please
carefully check the "L" line, "N" line and "PE" of each cabinet’s AC inlet, and ensure
there is no short circuit between the three lines (Use multimeter to measure).
• Power Supply Cabling Instructions
Please calculate and select the power distribution box or socket type based on
maximum power consumption. Please consult your power distribution box
manufacturer to specifically match.Cabinet’s input voltage is 100-240V/AC, and
3X1.5mm2 power cable is used to connect from distribution box cabinets.
