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.
