
Temperature map scenario
In the scenario where T/H sensors are connected, 32 T/H sensors are connected to one
UIM.

Each COM port allows a maximum of eight T/H sensors to be cascaded.

The addresses of the T/H sensors connected to the same COM port must be different. Addresses 1 to
8 are supported. The addresses of T/H sensors connected to different COM ports can be the same. In
actual configuration, bind sensors to the corresponding cabinets in sequence.

Each cabinet can connect to only one T/H sensor, a T/H sensor is automatically bound to the cabinet
after its DIP switch is set. The LCD of the T/H sensor displays the DIP switch address.
