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 “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

The upper 3 bits represent the sub-device. The sub-device codes for the MZA-4.7 are:

standard amplifier

= 000

page preset amplifier

= 001

standard preamplifier

= 010

page preset preamplifier

= 011

Examples: Addressing a zone 10 preamplifier: Binary 010-01010 or 2A hex Addressing a zone 10 amplifier: Binary 000-01010 or 0A hex Addressing all Zone amp & preamplifier: FF hex

Send ASCII “2A” Send ASCII “0A” Send ASCII “FF”
