Ethernet Protocol

The serial port provides data acquisition and control of the Mirage amplifiers by a home automation system, or PC.

The interconnecting cable must be "Straight Through." For Ethernet, TCP port 17037 is used.

Command Structure: <command> <zone> <data> <line feed>

Command

Zone

Amplifiers are encoded with up to 96 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:

• 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 amplifier: Binary 000-01010 or 0A hex Send ASCII "0A"

Addressing all Zone amp & preamplifier: FF hex Send ASCII "FF"
