Signal sending, receiving, and decoding is carried out using
BUS protocol, which ensures the interaction between the sys-
tem and the interface.
Connect the cables to the terminal board located in the sys-
tem's indoor unit panel.
NOTE:
Use a shielded cable or a twisted-pair cable to connect the sys-
tem interface and the indoor unit so as to avoid interference
problems.

close as possible to a Wi-Fi source.
