DATA LOGGER CONTROLS
The Data Logger panel allows you to log the digitized data
collected in a Microsoft® Excel file, giving you more flexibility
to monitor and compare data. However, you must set up the
data sampling rules using the following steps:

CONVERT PIN CONTROLS
The Convert Pin Control panel applies only to the
ADM1175 device.
Enter the number of times to perform a sample in the Set
log limit (0 = No limit) text box. The sampling rate is set
using the Readback update rate drop-down menu, as
discussed previously, there are four options to choose
from 100 ms, 200 ms, 500 ms, or 1000 ms. In the example
in Figure 28, the data logger logs 100 samples, with 100 ms
between each sample.
Click the Log data to file button. A file browser dialog box
appears for you to choose the file name and the location
where the data will be stored. Press B to start logging data
to the file. The data will be sampled at the chosen rate and
logged to the Excel file.
Once the data begins logging, the Total logged samples are
displayed at the bottom of the panel. This number increases
with the sampling rate and the log progress is complete
once it reaches the Set log limit value. Alternatively, you
may press the Stop data log to file button to terminate the
process. Once the data has been imported to the specified
Excel file, the data may be easily evaluated.

The jumper in LK3 should be in Position A to allow the
evaluation software to control the convert pin. If the jumper is
in Position B, the on-board switch, S6, can be used to control
the conversion.
The Convert Pin Control panel allows you to control the
analog-to-digital conversion of voltage and/or current. Four
buttons on the Convert Pin Control panel control the type of
data conversion carried out.

COMMUNICATION STATUS INDICATOR
Under the Readback update rate panel, there is a communica-
tion status indicator, see Figure 31. This shows the status of the
connection between the software and the device. There are
three possible type of indication (see Figure 31).
The first type indicates normal communication. The second
type, the spinning logo, indicates data being read to/written
from/to the register. The third type indicates that communica-
tion between the device and the user interface has been lost.
The software should be restarted (use the Software ON/OFF
button) to reestablish communications with the device.
The Press to Stop Converting button allows you to stop a
continuous conversion.
The Convert Once button carries out a single conversion
by issuing a single pulse onto the CONV pin. The result of
the conversion appears in the data display panel in the top
right hand corner of the Main Panel.
The Continuously Converting… button begins a
continuous conversion by pulling the CONV pin high.
The results of the continuous conversion are displayed
in the data display panel.
Once the Pulse Convert line button is pressed, a drop-
down menu appears as shown in Figure 30. You can choose
from one of four pulse frequencies. The four conversion
frequencies to choose from are once every 100 ms, 200 ms,
500 ms, or 1000 ms.
Note that in the case of the ADM1175 device, if you set
the Pulse Frequency, then you do not have the option of
changing the Readback update rate.
