Setting the DIP Switch
● The Arm7 main control board has the DIP switch, whereas the M4 does not
have. If the Arm7 main control board is used, set the DIP switch. If the M4
main control board is used, skip this step because there is no DIP switch.
● You need to set only the seventh toggle switch based on site requirements and
leave the rest of toggle switches in their default status listed in

● Figure 3-53 shows the scenario where every two smart cooling products connect to the
EMS over a Y-split cable. Determine the number of Y-split cables used for grouped
monitoring 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 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 host needs more 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 3-53.
