When the host monitors smart cooling products using the RS485 protocol, the time needed for
collecting all data from a single smart cooling product is 3 seconds. In the teamwork mode of
cascading using an RS485 bus for monitoring, it takes the host 3 seconds multiplied by N to collect
data from N smart cooling products in the group. For example, the time needed for collecting data
from four smart cooling products is 12 seconds. If the total monitoring time is too long, use the
solution shown in the following figure to connect single smart cooling products to independent
communication ports on the host. Choose the host monitoring mode based on the host parameters.
