Product Cabling
3.1 Attention of Cabling
LR series network cables and power cables are connected by aviation heads, as above:
Note: The connecting cables between the cabinets should pass through the cabinets as
much as possible. If the connection method changed, please set the same connection
method in the software settings. Please refer to the software for more details.
Note:
1. Load capacity of main power cable and main network cable.
2. Checking.
After the cabinet wiring is completed, use a multimeter to measure whether there is a
short circuit between the AC input (L / N / PE) and DC output (VCC / GND) of the power
supply. If so, please check the wiring carefully. Please make sure the circuit is normal
before power on. To avoid the entire screen being burned due to the wrong working
voltage, please pay attention to the working voltage range of the cabinet when use.
3. Turn on the screen and check the effect.
When the screen is powered on, play high-definition content, such as video, text, images,
etc. It is suggested to make sure the resolution of the content consistent with the
resolution of the screen, otherwise the content will be compressed, thus affecting the
overall performance.
4. For software operation, please refer to the software instruction manual.
Power cable routing: Details of the loaded box: When 220V power supply, a single power
line can load up to 16 cabinets, and when 110V power supply, a single power line can load
up to 8 cabinets.
Network cable routing: The signal cables are connected from left to right. Please calculate
the resolution according to the pixels of each cabinet. Note that the maximum load of a
single network port does not exceed 650,000 pixels.
