Data Transmission at Other Intervals
Programming the logger to perform data transmission using a different regime
requires selecting or setting several parameters:
1. Select the interval at which to send the data from the Transmission
Frequency drop-down list.
2. Designate the period of time within which the logger should conduct
data transmission in the Start and End fields. Choosing a frequency
of 12 or 24 hours only requires designating the time at which to
perform transmission during the selected day(s) in the Start time field.
3. Select the checkboxes corresponding to the days on which to have the
logger transmit data (based on the designated frequency and time
range) from the options under Active Days.
4. Select the order in which to send the data from the Data Transmit
Order drop-down list. Choosing Newest First ensures the logger
sends the most current data first.
For example, a logger could be programmed to transmit data every hour
between 8 am and 6 pm Monday through Friday.
Strategically managing the transmission times can maximize the life of the
battery in the logger. To manage the costs associated with SMS transmission,
the XiLog+ refrains from sending an SMS until the transmission will be
somewhat full, regardless of the selected frequency. Each SMS can contain up
to 96 values.
For example, logging data at a 5-minute interval for an 8-hour period will
produce enough data to fill an SMS transmission. Therefore, logging at this
interval, the XiLog+ would transmit data via SMS approximately every 8
hours, even if the logger is preconfigured to transmit data on an hourly basis.
This controls the costs associated with SMS transmission and prevents the
duplication of data.
Transmitting data via FTP does not involve these restrictions. At each
transmission interval, the XiLog+ will send all new data by FTP.
Optional Receive Frequency Window
This window contains the parameters for enabling the modem to receive data.
These settings are independent of the settings on the main data transmission
window.
