Setting Method
● Modbus RTU: If a smart cooling product needs
to connect to an EMS using an RS485 cable, set
Protocol to Modbus RTU.
● Modbus TCP: If a smart cooling product needs
to connect to an EMS through an IP address
network, set Protocol to Modbus TCP.
Set the baud rate as required. The value should be
consistent with that at the EMS side. This
parameter is configurable when Protocol is set to
Modbus RTU.
Set the address of the smart cooling product. The
EMS communicates with the smart cooling product
through this address, and the addresses of two
smart cooling products connected to the same
EMS must be unique. This parameter is
configurable when Protocol is set to Modbus RTU.
