Chapter 4 Installation
Precautions for Installation
1) The onsite installation shall be performed by the trained and qualified technicians. Please turn
to the after-sales service or agent of VTRON for technical instructions before installation. For
the equipment and personal safety, at least two technicians are needed to perform the
installation onsite.
2) When shipped from the factory, the Digicom HC Series Multi-Screen Processor is provided to
the user as a whole unit. All hardware board modules and software program modules of the
Digicom HC Series Multi-Screen Processor are produced in the factory according to strict
production procedures and have undergone a series of tests such as high temperature and
aging tests. Upon installation at the site of the user, the user only needs to connect the Digicom
HC Series Multi-Screen Processor to external equipment.
3) Before installing the Digicom HC Series Multi-Screen Processor, please check whether the
installation environment meets the requirements of Digicom HC Series Multi-Screen Processor
on its operating environment (e.g., temperature, humidity, power supply, grounding system,
etc.), so as to ensure that the equipment can be put into normal operation after installation, and
its service life can be guaranteed.
4) Please use the cables delivered together with the product (including the signal cable, network
cable, and power cable). If the user needs to use his/her own cable, please turn to the
after-sales service department or agent of VTRON for corresponding technical instructions.
Chapter 4 Installation
User Manual for Digicom HC Series Multi-Screen Processor 4-2
4.1 Installation environment
Before installing the Digicom HC Series Multi-Screen Processor, please check whether the installation
environment meets the requirements of Digicom HC Series Multi-Screen Processor on its operating
environment (e.g., temperature, humidity, power supply, grounding system, etc.), so as to ensure that the
equipment can be put into normal operation after installation, and its service life can be guaranteed.
Requirements on temperature and humidity:
Operating temperature: 0 ºC -40 ºC
Relative humidity: 20%-80%, no condensing
Requirements on power supply
The power supply for the Digicom HC Series Multi-Screen Processor shall be 110-240V 50/60 Hz.
Please make sure that such power supply can be provided in the installation environment. In addition, to
ensure the stability of the power supply to the Digicom HC Series Multi-Screen Processor, the power
socket of the Digicom HC Series Multi-Screen Processor must be connected to independent power
plugboard (220V 10A standard plugboard recommended). Do not share power plugboard with other
equipment.
Requirements on grounding:
Therefore, when installing the Digicom HC Series Multi-Screen Processor, you need to fully consider the
grounding measures of the whole system environment, including whether the power supply has the
grounding measure (e.g., adopting the certified three-core power cable and power socket).
Corresponding equipment grounding terminals should be reserved in the on-site system grounding.
When there are insufficient grounding terminals in the system grounding, it’s necessary to increase the
number of equipment grounding terminals by increasing the number of grounding bar. (The resistance
between the on-site reserved system grounding terminals and the protection ground should be lower
than 3 ohms).
Chapter 4 Installation
User Manual for Digicom HC Series Multi-Screen Processor 4-3
Besides, when installing the Digicom HC Series Multi-Screen Processor in the high-rise building, the
equipment shall be connected to the true earth through the dedicated safe grounding system and kept
away from the SPD grounding system of the building. Improper system grounding will have large
negative effect on the signal transmission, which will result in the imaging interferences that cannot be
removed through debugging. For details, please consult VTRON. Please strictly comply with the relevant
instructions and maintain proper grounding during the use of the equipment.

4.3 Connection to Peripherals
Connection to display equipment
Use the signal cable delivered with the product to connect the output interface of the Digicom HC
Series Multi-Screen Processor to the corresponding input interface of the display equipment or
processor.
Note:
Digital signals have strict requirements for signal transmission; therefore, the user is advised to
use the signal cable provided by VTRON. Please consult VTRON or an agent before
attempting to use non-proprietary signal cables.
Connection to a signal source
Connect the CVBS input channels on the Digicom HC Series Multi-Screen Processor to the output
channels on your CVBS signal sources, with the CVBS video signal cables delivered with the

product; connect the VGA signal input channels on the Digicom HC Series Multi-Screen Processor
to the output channels on your VGA signal sources, with the delivered VGA signal conversion cables;
connect the DVI signal input channels on the Digicom HC Series Multi-Screen Processor to the
output channels on your DVI signal sources, with the delivered DVI signal conversion cables
delivered with the product.
The VGA signal source onsite generally refers to the operating PC, professional workstation, or the
matrix connected to such equipment. There are many types of video signal sources, including
common video player equipment and cameras. Since there are many video input channels, make
sure to connect the correct channel to the corresponding signal source. Only in this way can you
correctly access the video signal source in the applications.
The following figure illustrates an example with a VGA signal input. Because other types of signal
sources are similar to this, no further description will be provided.

User Manual for Digicom HC Series Multi-Screen Processor 4-8
Connection with network cable
The Digicom HC Series Multi-Screen Processor can be physically located in the network and can
also be controlled through the network. Therefore, in actual application, the user needs to connect
the Digicom HC Series Multi-Screen Processor with the network through switching equipment, that
is, to use network cables to connect the switching equipment with the network interface. The
network interfaces to be connected depend on the onsite network availability.

The power socket of the Digicom HC Series Multi-Screen Processor is located at the bottom left
corner of the rear panel of the equipment, as shown in the following figure.
When connecting the equipment power socket and the plugboard, please use the cable delivered
together with the equipment. Incompliant power cable will affect the power supply, performance stability
and safety of the equipment. In addition, to ensure the stability of the power supply to the Digicom HC
Series Multi-Screen Processor, the power socket of the Digicom HC Series Multi-Screen Processor must
be connected to independent power plugboard (220V10A standard plugboard recommended). Do not
share power plugboard with other equipment.

Administration Software: VWAS (Optional)
The VWAS (VTRON Display Wall Administration System) is the application administration system
developed by VTRON for the development, design, and production of the display wall system and its
multi-screen processing system. It is mainly used to control and manage the hardware in the display wall
system (e.g., the display unit, the multi-screen processor, and other peripherals), so as to realize the
management and control of the signal windows and application windows shown on the display wall. The
VWAS can make full use of network distributed software systems and support simultaneous connections
and the operation of several clients. It provides a simple, friendly, and customized man-machine
interface, allowing for quick and convenient control and simple operation using the combined display
wall and completely eliminating the shortcomings of traditional display walls, i.e., complex operations.
