2.1.5 Data Acquisition (DAS)

The Model 300M contains a flexible and powerful built in data acquisition system (DAS) that enables the analyzer to store concentration data as well as many diagnostic parameters in its battery backed memory. For more information on programming custom Data Channels, a supplementary document containing this information can be requested from Teledyne API.

2.1.6 RS-232 Interface

The M300M CO Analyzer features an RS-232 interface which can output the instantaneous and/or average CO data to another computer. It can also be used as a command and status channel to allow another computer to control the analyzer. Refer to Appendix Figure A-1 or Appendix A for details on the RS-232 interface.

2.1.7 Password Protection

The M300M CO Analyzer provides password protection of the calibration and setup functions to prevent incorrect adjustments to the analyzer. There are two levels of passwords which correspond to operator, supervisor/maintenance, and analyzer configuration functions. When prompted for a password, any of the valid passwords can be entered, but the CPU will limit access to the functions allowed for that password level. Each level allows access to the functions of all the levels below plus some additional functions. Table 2-1lists the password levels and the functions allowed for each level.
