Teledyne API Model 100AH SO2 Analyzer Instruction Manual, 02417, Rev. D
7.2 Command Summary
The information contained in the rest of this section covers all of the normal commands that are
required to operate the instrument from a remote terminal. If you are going to be writing
computer programs to communicate with the M100AH (i.e., operating the port in COMPUTER
MODE) we suggest that you order a supplementary manual "The RS-232 Interface", Teledyne
API part number 01350. This manual shows additional features of the port designed to support a
computer driven interface program.
There are 6 different types of messages output by the M100AH. They are grouped below by type
in Table 7-4, Table 7-5, and Table 7-6. The meanings of the various messages are discussed
elsewhere in the manual. The TEST, DIAGNOSTIC and WARNING messages are discussed in
Section 10.1, 10.2. DAS and VARIABLES are discussed in Section 5.3.3 and 5.3.9.
CALIBRATE is discussed in Section 8.
