3.5 Connection of network cable
The Digicom AP series multi-screen processor can work in the network. You can also
control the processor through network. In actual application, you need to connect the multi-
screen processor to the network through exchange, that is, to connect the exchange to the
network interface with network cable. The network interfaces to be connected depend on
the onsite network availability.
3.6 Connection of power cable
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 multi-screen processor, the processor power socket must be
connected to independent power plugboard (220V10A standard plugboard recommended).
Do not share power plugboard with other equipment.
3.7 System grounding
To ensure the safety and stability of the equipment as well as the safety of the operator, the
equipment must be properly and securely grounded. That is, the grounding terminal on the
enclosure must be connected to the dedicated grounding system with dedicated grounding
conductor through proper method.
Note: to ensure the safe operation and the normal working of the system, the electric
grounding of the electronic product is compulsory. Improper grounding will severely affect
the reliability and stability of the system and cause negative impact on the signal quality.
Therefore, when installing the Digicom AP 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). Besides, when installing the Digicom AP 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.
