−	~~== Virtual Address (VA) Concept ==~~
−	In order to simplify translation of the UID (like '''L5.102''') into Modbus object address, CoolMasterNet uses VA, associated with UID. Each UID can have none, one or a number of associated VA's. VA's are plain numbers starting from 001 (decimal). To let CoolMasterNet automatically associate VA's with existing (visible with '''ls''' command) UID's run:
−	~~{{Terminal\|~~
−	~~>'''va auto'''<br>~~
−	~~OK<br>~~
−	~~>}}~~
−	~~This command will delete all existing associations and will create new associations one to one (one VA to one UID). At any time VA associations list can be retrieved with plain '''va''' command:~~
−	~~{{Terminal\|~~
−	~~>'''va'''<br>~~
−	~~L1.101 --> 001~~ [~~Hex: 0x0011 \| Dec: 00017]<br>~~
−	~~L1.102 --> 002~~ [~~Hex~~: ~~0x0021 &~~#~~124; Dec: 00033]<br>~~
−	~~L1.103 --> 003 [Hex: 0x0031 \| Dec: 00049]<br>~~
−	~~L1.104 --> 004 [Hex: 0x0041 \| Dec: 00065]<br>~~
−	~~L1.105 --> 005 [Hex: 0x0051 \| Dec: 00081]<br>~~
−	~~OK<br>~~
−	~~>}}~~
−	Hex and Dec numbers printed after VA are Base Address used to access Modbus objects related to UID-VA association. Base Address can be calculated as '''''BaseAddress = VA16 + 1'''''. For example Indoor Unit L1.102 has associated VA = 002, thus Base Address = 216+1 = 33.
−
−	~~== Discrete Inputs, Coils and Registers ==~~
−	~~Once the Base Address is determined, access to the specific Indoor Unit parameter(s) is done via Modbus objects listed below.~~
