 "summary": "CoolMasterNet and the CooLink family connect to the AC manufacturer's indoor-unit bus and serve every indoor unit as the same 16 BACnet objects, over BACnet MS/TP and/or BACnet IP. Instance numbers are built from the unit's virtual address (VA): instance = VA x 256 + object index. Configuration is done with text commands on the gateway's ASCII interface.",
