Description
Set this parameter based on the baud rate of the
connected device. The baud rate must be the
same as that on the NMS. The value can be 9600
or 19200.
Enter the communications address of the smart
cooling product as planned. The NMS
communicates with the smart cooling product
using this address, and the communications
addresses of two smart cooling products
connected to the same NMS must be different.
● In non-grouping scenarios, set RS485
monitoring grouping to Enable for each unit.
● In grouping scenarios, set RS485 monitoring
grouping to Enable for the unit with the
COM/FE port connected, and Disable for
other units.
