RTU Protocol)
When the host monitors smart cooling products over northbound RS485 ports, it
takes 3 seconds to collect all data of a single smart cooling product. Therefore, the
time required for collecting data from
seconds. If the time required for the host to collect data of all smart cooling
products does not meet performance requirements, the smart cooling products
can be grouped for data collection. For example, if the host needs to collect data
of all smart cooling products within 12 seconds, it is recommended that every four
smart cooling products be divided into one group. Connect the COM-IN port on
the main control module of the first smart cooling product in each group to the
host.
