Zone
Ampliers are encoded with up to 32 zones.
The zone byte is used for checking if the command is applicable to the device receiving the command and if so, for optionally selecting a “sub-
device”, e.g. a bank or part of a device. All Zones are addressed using FF.
The lower 5 bits of the zone byte represent the zone 0 – 31
selection, i.e:
» 00000 bin = 00 (hex) = zone 0
» 00001 bin = 01 (hex) = zone 1
» 01010 bin = 0A (hex) = zone 10
» 11111 bin = 1F (hex) = zone 31
Examples:
Addressing a zone 10 amplier: Binary 000-01010 or 0A hex Send ASCII “0A”
Addressing all Zone amp & preamplier: FF hex Send ASCII “FF”
