The initial value is 0
Used for setting the baud rate of Rs485 port, and the
gateway is used 4800 baud rate.
The value is fixed to be 2.
The gateway address of the Air-cooled Modular unit
system. “Address” must be set the corresponding
value, as displayed in Table A

Corresponding address of wired controller
Caution
First power on, it needs to set the gateway property as the actual conditioner, then connect the gateway which
has been set to the Air-cooled Modular system.
* In a Air-cooled Modular system, there are wired controller and gateway, the address which the address
variable of the gateway (nciCtrl_Addr) corresponds to the address of wired controller must be larger than all
the wired controller addresses (As displayed in Table A).
Gateway address setting example: One Air-cooled Modular system, there are two wired controllers, the
addresses are 0, 13, and as displayed in Table A, the gateway must be set to 241 or 240, for only 241 and
240 corresponding addresses of wired controller are larger than the wired controller address 13.
The network variables which are assigned to the Air-cooled Modular system:
The network variable of Air-cooled Modular system: 4 input network variables, used for setting; 8 output
network variables, used for query. As the following figure:
