3.12.4.4 Connecting the Monitoring Network Cable

The smart cooling product supports both RS485 and FE monitoring.

3.12.4.4.1 Connecting the FE Monitoring Network Cable (SNMP/Modbus-TCP)

The FE monitoring and FE teamwork control use the same network cable. For the connection
method, refer to

3.12.4.4.2 Connecting the RS485 Monitoring Network Cable (Modbus-RTU)

When monitoring smart cooling products over northbound RS485, the EMS needs 4 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 4 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 finish data collection in 16 seconds, you are advised
to group smart cooling products by four and connect the COM–IN port of the main control
module of the first smart cooling product in each group to the RS485 port of the EMS.
