Instruction Code
This is a three-character alphabetic sequence that identifies the subject of the message. Wherever possible, the instruction codes have
been chosen to have some significance.
For Example:
GAC
for
G
lobal
A
mplifier
C
onfiguration;
IPA
for
IP A
ddress, etc. This aids in the readability of the message, should it be
displayed in its raw ASCII form.
Both upper case and lower case alphabetic characters may be used (A-Z
and
a-z, ASCII codes 65-90
and
97-122).
5.3.4.5
Instruction Code Qualifier
This is a single character that further qualifies the preceding instruction code. Code Qualifiers obey the following rules:
1. From Controller to Target, the only permitted values are:
Symbol
Definition
=
(ASCII code 61)
The ‘=’ code is used as the Assignment Operator (AO) and is used to indicate that the parameter defined by the preceding byte should
be set to the value of the argument (s) which follow it.
EXAMPLE: In a message from Controller-to-Target, MUT=1 would mean ‘enable the mute function’.
?
(ASCII code 63)
The ‘?’ code is used as the Query Operator (QO) and is used to indicate that the Target should return the current value of the
parameters defined by the preceding byte.
EXAMPLE: In a message from Controller-to-Target, MUT? denotes ‘return the current state of the mute function’.
