Sensor Values: GENERIC, P, SENSOR, AUTO

GENERIC, P, SENSOR, AUTO, line number, start

GENERIC, P, SENSOR, LINE, line number, start, end

In AUTO mode, sensor values are delimited by blanks or commas and there

may be several per line. If the line number parameter is not given

(example 1 above) then data is assumed to start on the first line of the

report. If the line number is given, data can start on other than the first

line. In addition, if the “start” parameter is given, data can begin in a

column other than the first column. For example you may have a report

such as the following:

10/14/02 09:15:00 +123.4 +19.8 +33 +99 -1089.45...<cr><lf>

Notice it has a date, time, then data values on the same line. In this case

you would use a GROUP,P,SENSOR,AUTO,1,18 command to locate the

start of the sensor data, and use the AUTO method of locating the rest of

the data.

In LINE mode, sensor values will start on the given line number and start-

end columns, then will repeat, either in free format, or one value per line,

depending on the report type.

Polling: GENERIC, P, POLL, poll string, interval

The polling feature can be used for data loggers that do not print a data

report unsolicited, but require some command string to be sent to request

the next report. The poll string can be any printable ASCII characters up to

20 bytes in length. The “interval” parameter is given in decimal and is the

number of seconds between outputting the poll string. If a poll is output,

the response string from the data logger will be parsed in the same manner

as when there is no poll string required. If the data logger echoes the poll

string, this will look like part of the report and must be accounted for in

the setup. To handle data loggers that need to wake up from a low-power

mode, the poll string will be preceded by a carriage return and line feed,

and the poll string will be followed by another carriage return and line

feed.

Polling using binary (non-printable-ASCII) characters is not yet supported.

Start of Report: GENERIC, P, REPORT, Report String
