swapped at one end) Only RX , TX & 0V (pin 5) are used.

Baud Rate = 9600 , Characters are all ASCII.

60 – 6F User defined IR commands, no data byte

70 – 7F User defined IR commands, one data byte

Zone Axium 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.

The lower 5 bits of the zone byte is 00 – 1F for zones 1 to 32. The upper 3 bits represent the

sub-device. FF means all zones and can be used for turning all amplifiers ON.

The sub-device codes for the AX4752 amplifier are as follows:

000 standard amplifier

001 page preset amplifier

010 standard preamplifier

011 page preset preamplifier

For example addressing a zone 10 preamplifier = (Binary 0101010, Hex = 2A) Send ASCII ‘2A’

1 2 ... 11 12 13 14 15 16 17 18 19 20 21 ... 27 28
