3.11.5.3.1 Northbound RS485 Monitoring
When monitoring smart cooling products over northbound RS485, the EMS needs
3 seconds to collect data from one smart cooling product. Therefore, the time
required for collecting data from N smart cooling products in a group is 3 x N. If
the data collection time is longer than the performance requirement, you can
divide the smart cooling products into several groups. For example, if the EMS
needs to
nish data collection in 12 seconds, you are advised to group smart
cooling products by four and connect the COM port of the main control module of
the
rst smart cooling product in each group to the RS485 port of the EMS.

and connect the monitoring network cables.
● If there is no teamwork control or in FE networking, connect the COM port on
each smart cooling product to the customer's monitoring system.
● In CAN networking, connect the COM port on the
rst smart cooling product
in each teamwork control group to the monitoring device.
