B-8 824 Reference Manual 9/12/00
Selected bits in ConfigFlag can be tested. If any of the spec-
ified bits are set = 1, then the response will be “Yes” other-
wise 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.
F3 E0 M3
R1,2 All Read Model string “824” 824
R1,3 All Read Flash Identification “hhhh” Manf/Device Code (IF
13)
IF 13
R1,4 All hhhh (options installed in hex)
R1,5 All Reads out the RTC’s (real-time clock) serial number in
hexadecimal
R1,128 All Read ConfigFlag “hh” (in hex)
R1, n All Test selected bits in Configflag. (n=129-255)
