The "X" indicates the message type as shown above in Table 7.1 and "COMMAND" is

the command type, each of which is described individually below.

The "<CRLF>" is used to terminate the command. Typing "<CRLF>" a few times by

itself is a good way to clear the input buffer of any extraneous characters.

7.1 DAS reporting

Data from individual Data Channels in the DAS system can be retrieved through the RS-

232 interface. The command format for printing the data for a Data Channel is shown

below:

D [id] REPORT “name” [RECORDS=number] [COMPACT|VERBOSE]

parameters in [ ] are optional

id is the analyzers ID number (SETUP-MORE-COMM-ID)

name is the Data Channel name(must be enclosed in quotes)

number is the number of records to print, beginning with the most recent(if this

parameter is not specified then all available records for the Data Channel are printed)

COMPACT|VERBOSE refers to the report format.

Verbose Data Report Format

There are two kinds of data reports: verbose (with a lot of detail) and compact

(with just the data point values). The verbose format looks like the following:

D 31:10:06 0412 CONC : AVG COCNC1=6.8 PPM

This report uses the format of a leading first character (“D” in this example), a

time stamp (“31:10:06”), and the instrument ID (“0412”).

The other fields in the report are the data collector name (“CONC”), the sampling

mode (“AVG”), the data point (“COCNC1”), the data point value (“6.8”), and the

units (“PPM”). Due to the length of the message, only one data point may be

printed per line.

Compact Data Report Format

The compact format looks like the following:

D 31:10:06 0412 CONC : 1 6.8

The fields up to the colon are the same as for the verbose format, but the next

fields are different. The fields following the colon are the line number (“1” in the
