3.3.2.3 RS-232 PORT

The digital signal output is a standard, full duplex RS-232 serial communications port used to connect the analyzer to a computer, terminal, or other digital device. It requires a standard 9-pin D connector.

The output data is status information, in digital form, updated every two seconds. Status is reported in the following order:

∙The concentration in ppm or percent

∙The range in use (HI, MED, LO)

∙The span of the range (0-100 ppm, etc)

∙Which alarms—if any—are disabled (AL–x DISABLED)

∙Which alarms—if any—are tripped (AL–x ON).

Each status output is followed by a carriage return and line feed.

Three input functions using RS-232 have been implemented to date. They are described in Table 3-5.
