In this case, all IDU numbers will be automatically offset. One minute later, conflict is
addressed and the system returns to normal. The offset can be set on only the master ODU
whose centralized control address is 0.
Note: If the quantity of conflict IDU numbers is not large, you are advised to manually set
them using Gree Debugger, control panel, or remote control. Manual setting is applicable to
intra-ODU conflicts only, not affecting numbers of other IDUs. If the quantity is large,
automatic offset is recommended, which is easy to realize. However, numbers of normal
ODUs may be altered. Automatic setting is applicable to initial installation and debug.

As shown in the preceding figure, the master ODU and the Modbus gateway at both ends of the CAN2
bus need to be configured with matched resistance.
The following figure shows how to set matched resistance on the Modbus gateway at the end of the
