Historical Data 12
The normal sequence for a data logger to load data into the modem at a normal scheduled update
time is as follows:
AV Send the AV command just to get its attention
AVTIME=HH:MM:SS Send the time to the modem, time is stored in top box in the table.
AVBOX01=12.34 Send data for data box 01, data stored in top box of the table.
AVBOX02=56.78 Send data for data box 02, data stored in top box of the table.
AVSHIFTVALUES Shift values so data in row 12 is lost, row 11 moved to row 12, row
10 moved to row 11, continued on until row 0 is stored in row 1.
If the user requests data on demand, then the same sequence is followed except the shift
command is not issued. The new data is in row 0 and all the historical data in the other rows
remains the same. Again the data logger automatically issues these command to load the data
into the modem.
3.3.2 Voice Call In Options
On the XL Series data logger use the ‘Voice Modem’ options menu to select what data will be
sent to the modem, how often and in what order. Refer to the XL Series manual for full details
on setting up the voice modem options.
On the H-2191 modem, the main setups required are to enter the voice messages that will be
spoken when the modem answers the call. This will be a site identification message and any
messages needed to identify the data values. To use the menu to make these changes, connect a
PC to the RS-232 port and using Hyper Term enter the following commands to get he menu.
