Network of the Long-distance Monitoring System

4.6.2.1 Net Topological Diagram
Note: the system as shown in the figure above consists of 1~16 single units depending on
the actual demand of the project.
From the topological diagram above, the long-distance monitoring system consists of 3
parts：
The first part is the BMS and the converter used to convert RS232 signals from the BMS into
RS485 signals of the long-distance monitoring network.(it is required only when RS232 is used
for the BMS)The second part refers to the communication network, that is, the communication
lines and the connected hardware.
The second part refers to the communication network, that is, the communication lines and
the connected hardware.
The third part is the patching board responsible for the data exchange between the air
conditioning system and the monitoring PC. When there is only one unit, the patching board is
A Series Modular-type Air-cooled (Heat Pump) Chiller
