 Figure 3-53 shows the scenario where every two smart cooling products connect to the EMS over a
Y-split cable. Determine the positions of Y-split cables based on performance requirements.
 When the EMS 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 EMS 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 EMS needs longer time to collect data from
all smart cooling products than what the EMS performance requires, use the Y-split cable connection
scheme shown in Figure
