Selected bits in ConfigFlag can be
tested. If any of the specified bits are
set = 1, then the response will be
“Yes” otherwise the response is
“No”. The following examples show
how bits in ConfigFlag can be tested.
(The binary number shown is the
binary value of the decimal operand
of the R1 command.)
R1, 1 All Option feature identification. (8 characters)
Used to determine optional features of the system. The
returned string will show the availability of a filter card,
the ENV firmware option and the memory options. The
filter has 3 options: None (F0), 1/1 octave filters (F1) and
1/1 plus 1/3 octave filters (F3). The Environmental noise
analyzer option is either present (E1) or not (E0).
The memory has 4 options.
Standard 1/2 megabyte (M0), 1 megabyte (M1), 1.5 mega-
byte (M2) and 2 megabyte (M3).
Example: “F3 E0 M3” means there is a 1/3 octave filter
installed, there is no ENV option, and the memory is the
standard 2 megabytes.
