Indoor unit and outdoor unit communication
A
HyperLink (M1M2) communication (with independent power supply)
Single unit: HyperLink (M1M2) communication is a new type of indoor unit and outdoor unit communication technology.
When the indoor units are provided with independent power supplies, use 2×1.5mm2 communication
cables. M1 and M2 ports are located at terminal block "CN10" of the main control board. There is no
distinction between negative and positive electrodes. For details, see the following figure:

CAUTION
Do not connect the HyperLink (M1M2) communication wiring to the PQ or D1D2 communication wiring.
System: The HyperLink (M1M2) communication wiring with an independent power supply between indoor unit
and outdoor unit can reach a length of up to 600 meters, supporting any topology connection. The
following figure shows a serial connection:
