Temperature map scenario
In the scenario where T/H sensors are connected, 32 T/H sensors are
connected to one UIM.
NO TE
– 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.
– One UIM connects to 32 T/H sensors. If the smart module connects to more than
32 IT cabinets, two UIMs are required for expansion. Each UIM must be installed in
the first cabinet of the corresponding IT cabinets, and the cable connection
principles remain unchanged.
– In this scenario, a UIM is not bound to the IT cabinet.
– Only the T/H sensor inside the cabinet can be connected to the UIM.
