Page 106 MRC-565 Packet Data Radio Operations & Maintenance
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 1
st
line of the report. If the line number is given, data can start on other than the 1
st
line.
In addition, if the start parameter is given, data can begin in a column other than the 1
st
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
The report string allows the definition a fixed string of printable ASCII characters that is at the
beginning of each new set of report characters. This is useful for ignoring bursts of non-report
text. Each report is started with the report string and ends with the timeout parameter. If the
cable between the data logger and MRC-565 is connected part way through the output of one
report, and the report string text is "missed", then a partial report will not be created.
Remote Commands: GENERIC, P, COMMAND, Command String
Some support for remotely commanding and configuring a generic data logger is provided using
this command format. If the data logger can accept commands as a single line of text (no
embedded <cr><lf>) without having to be locally present at the data logger to type keys into a
menu, then this capability may be just the ticket. When a remote command is received by the
MRC-565, it will output the Command String bytes to the data logger preceded and followed by
