2.1.6 RS-232 interface

The Teledyne API 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 Figure 1.3 for details on using the RS-232 interface. Tips on connecting the RS-232 port can be found in Appendix B.

2.1.7 Password protection

The Teledyne API CO Analyzer provides password protection of the calibration and setup functions to prevent incorrect adjustments to the Analyzer. There are three 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.
