DEMO MANUAL DC2260A
OPERATING THE CONTROL SCREEN
For convenience, the control panel allows for continuous
operation of the DC2260A board. When the command
button labeled START CONTINUOUS READ CELLS is se-
lected, the GUI operates in a continuous loop executing
the following command sequence automatically:
n Start cell voltage
n Read cell voltage groups A (1 –3) , B (4 –6), C (7 –9),
and D (10 – 12)
n Read flags
Options available are the READ DISPLAY box, ADC SET-
TINGS box, OPEN WIRE TEST CURRENT box, and the
CONTINUOUS box. The CONTINUOUS box allows the
selection of STARTCELL, STARTOPEN, STARTCELL DCC,
and STARTOPEN DCC commands to be executed during
continuous operation. The options are useful for monitor-
ing the cell voltage measurements under different ADC
Test Conditions.
All values are updated continually (update rate is~500ms).
While running, the configuration can be changed on the
fly. Simply changing a configuration item (Discharge cells
for example) and clicking the WRITE CONFIG button will
implement the new configuration and return to continu-
ous operation.
A green box with the label ON in the lower right corner
of the GUI indicates that the system is running continu-
ously. A red box with the label OFF means that the system
is stopped and waiting for a new command to be sent.
DATALOGGING OPERATION
The GUI program can “datalog” or store cell voltage re-
sults in a CSV (Comma Separated Value *.csv) file. This
feature is useful in characterizing cell voltages over time.
Datalogging operates similarly to continuous operationbut
has the added functionality of storing results in a CSV file.
1. At the upper left of the GUI, click on the Datalog Menu
then Enable Datalog.
Datalog Mode is enabled when a maroon box appears to
the left of the START CONTINUOUS READ CELLS com-
mand button and the red box label changes from OFF to
DATALOG OFF. Datalog Mode is disabled when the maroon
box disappears and the red box label reverts to OFF.
NOTE: The *.csv filenames include the time created and
are stored by default into the “C:\Datalog6804_6811\”
folder. More details are in the file “AboutCurrentVersion.
txt” inside the GUI’s installation folder (normally “C:\
ProgramFiles\LT C \MultiCellBatteryMonitor\LTC6804”).
2. Click on the START CONTINUOUS READ CELLS com-
mand button to start datalogging onto a new CSV file.
Elapsed Time =Total time of Datalog from start to finish.
Total Data Points =Total data points of Datalog from
start to finish. Refresh =Time in seconds (S) between
each Read Cells command;also known as Sample or
Update Rate.
3. Click onthe STOPCONTINUOUS READ CELLScommand
button to stop datalogging and close the CSV file.
