Important notes
Warning
To ensure reliable use of devices and safety of personnel, please observe the following items in
the installation, use and maintenance.
Notes in installation
◆Do not use this product in the following places: Where exists dust, smoke, conductive dust,
corrosive gases or flammable gases; where exposes to high temperature, condensation or wind and
rain; where exists vibration and shock. Electric shock, fire, incorrect operation will also lead to product
damage and deterioration;
◆During screw hole processing and wiring, metal chips and wire heads shall not be dropped into
ventilation holes of controllers, which may cause a fire, malfunction or incorrect operation;
◆When the installation work is done, make sure that no foreign body is left on the surface of
ventilation, including contact paper and other packaging materials, otherwise it may lead to poor
run-time heat, causing a fire, malfunction or incorrect operation;
◆Avoid wiring or inserting/pulling plugs in charged state, otherwise it may easily lead to electric shock
or cause damage to the circuit;
◆Installation and wiring must be solid and reliable, poor contact may result in incorrect operation;
◆For application in occasions with severe interference, shielded cables should be used to input and
output high-frequency signal so that anti-interference performance of the system could be improved.
Notes in wiring
◆All of the external power supply must be cut off before carrying out installation, wiring and other
operations, or it may cause electric shock or equipment damage;
◆This product is grounded through the grounding conductor of the power cord. In order to avoid
electric shock, the grounding conductor must be connected to earth. Before connecting the input or
output terminals of the product, make sure that the product is properly grounded;
◆Once wiring is completed, foreign matters should be immediately removed. Please cover the
terminal covers of product before power connection to avoid electric shock;
Notes in operation and maintenance
◆Do not touch the terminal when power is on, or it may cause electric shock or incorrect operation;
◆Perform cleaning and terminal tightening when power is off, for these operations may cause
electric shock when power is on;
◆Perform connection, removal or other operations of the communication signal cables and the cables
of expansion board or control unit after power is off, or it may cause equipment damage or incorrect
operation;
◆Do not disassemble the equipment, so as not to damage the internal electrical components;
◆Always read the manual, after security fully recognized, changing the program, commissioning,
starting and stopping operations after security is fully recognized;
◆Button batteries must be replaced when the power is off. When you indeed need to replace the
button batteries with the power on, the operation should be performed by a qualified electrical

technician wearing insulated gloves.
Notes in product obsolescence
◆Explosive electrolytic capacitors: It may cause explosion when electrolytic capacitor on the circuit
board burns;
◆Please collect and process separately, it cannot be put in the life garbage.
◆Please process it as industrial waste, or process it in accordance with local environmental
regulations.
◆Please turn off or disable the Loop / Daisy Chain function on the Video Wall Screens when
connecting to the VW Series chassis. This function might cause conflict to VW Series input and output
signal. Using VW series controller with Loop / Daisy Chain function is considered as improper
connection, Warranty will be Voided.
◆In case of using signal converter, only use the active converter to maintain proper signal and
electrical characteristic. Passive converter might cause signal loss or power surges.
Notes in Specialized Video Wall Screens connection
The warranty only covers failures or malfunctions that occur during the warranty period and under
normal use conditions as well as any material or workmanship defect.

2.5.13 DB15 male socket transfer cable
definition
VGA input board of matrix supports the input
of analog, composite video and component video;
VGA output board supports the output of analog,
composite video and component video. If users
need input or output component video signal, they
need connect DB15 male socket transfer cable(S
terminal, RCA head). The two kinds of connection
are different, two things should be noticed:
1. the connection of VGA input board: support
VGA, CVBS and YPbPr signal; when CVBS and
YPbPr signal are needed, only three lines of
DB15 male socket transfer cable terminal are
useful. As shown above, the connection of YPbPr
signal is Y attached to green line, Pb attached to
blue line, Pr attached to red line; For CVBS signal,
green line is the right one, signals can be
recognized automatically, no setting is needed
(VGA input port can access three signals, but one
port can only attach to one signal a time).
2, the connection of VGA output board: support
VGA, CVBS and YPbPr signal; when CVBS and
YPbPr signal are needed, four lines of DB15 male
socket transfer cable terminal are useful. As
shown above, the connection of YPbPr signal is Y
attached to green line, Pb attached to blue line, Pr
attached to red line; For CVBS signal, only yellow
line is the right one. VGA or YPbPr signal output
requires instruction setting; CVBS output has
always been on, no setting is needed.
