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 2-1 lists the password levels and the 
functions allowed for each level.
