normally sent to the modem each time the logger scans the different sensors. For example if the
logger is set to scan the sensors every 15 minutes, then data is normally sent to the modem every
15 minutes. For more instructions on this feature, please see the corresponding section in the XL
Series data logger owner’s manual.
The data coming from the data logger will be stored in memory locations referred to as data value
boxes within the H-219X. There are ten data value boxes labeled BOX01 to BOX10. As data is
sent from the data logger to the modem it is placed in data box01 and continues until no more
data is sent or all the data boxes are full. A time stamp is also sent to the modem so the time the
data value was measured is known. The following table gives a simple visual representation of
how data is stored in the modem.

Each data box has a user programable message that will be spoken to identify the data when a
voice call is made. A typical message would look like the following:
“The battery voltage is $v01 volts”
Notice the ‘$’ character in the message. The ‘$’ is used by the system to perform some task at
that point. The character just after the ‘$’ indicates the action to take. In this case the next
character is a ‘v’ which stands for ‘data value’. So in the above message the $v01 means insert
the value from data box 01 into the message when it is spoken.
For example, if the value in box01 is 34.25 and the user programmed the message for box01 to
“The stage is $v01 feet” then the unit would speak “The stage is 34.25 feet", and then move on to
the next data value if it is valid.
Now besides there being 10 different data boxes like a columns a table, there are also multiple
rows to hold older data.
Currently, this is a 10 by 13 table used to hold the data values. This is basically 10 values wide
for the different types of data and 12 values deep for historical data. One extra row of data for
non scheduled updates.
