Zone
Integra amplifiers and keypads 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
–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
–The upper 3 bits represent the
• | standard amplifier | = 000 |
• | page preset amplifier | = 001 |
• | standard preamplifier | = 010 |
• | page preset preamplifier | = 011 |
