In the non-teamwork networking scenario, connect one communications port of the
device to the COM port on the ECC collector.
When networking multiple air conditioners of the same model in teamwork mode,
connect monitoring cables and set DIP switches by following instructions in
4-212.
Reserve teamwork communications port 1 of device 1, connect its teamwork
communications port 2 to teamwork communications port 1 of device 2, and teamwork
communications port 2 of device 2 to teamwork communications port 1 of device 3. In
this way, all devices to be monitored in group are connected, as shown by the CAN bus
in Figure 4-212.
During teamwork networking and host RS485 monitoring networking, the teamwork
communications port of the first or last air conditioner indoor units must be connected to
the ECC COM port, as shown by the RS485 bus in
Set DIP switch toggle 7 to ON for the first and last air conditioners, and set the switch
