DEMO MANUAL DC2260A

Information furnished by Linear Technology Corporation is believed to be accurate and reliable.  

However, no responsibility is assumed for its use. Linear Technology Corporation makes no representa-

tion that the interconnection of its circuits as described herein will not infringe on existing patent rights.

4. The CSV file is ready to view. Go to “C:\Data-

Log6804_6811\” folder and open file.

2. A tab will appear on the left edge of the control panel 

for each board on the stack. Clicking on any of these 

tabs will transfer control commands and data to and 

from the display screen to that selected board.

3. Select whether the ADC’s Voltage Reference Powered 

State (Ref Up) and Over-/Undervoltage thresholds for 

each board are to be the same (GLOBAL) or different for 

each board (CUSTOM) and set the Ref Up and voltages 

accordingly.

COLOR CODED STATUS PANEL

The color-coded status panel will expand to include all 

boards connected in a stack. Each small square in this 

array represents an individual battery in the stack of 

boards. The intent of this display is to provide a way to 

see the status of all cells at a glance. The significance of 

the colors used is explained in the legend on the screen.
Consult the data sheet for detailed information concerning 

the operation of the LTC6811-2.

COMMANDS SUPPORTED (V05 VERSION):

POLLADC
WRITE CONFIG (REFUP, VUV, VOV, Discharge selected cells)
READ CONFIG
START CELL and OPEN WIRE conversions with and without 

discharge connected (ADC Settings: Conversion Mode, 

Open Wire Test Current)
READ CELL GROUPS (A, B, C and D. Read Volts/Hex)
START CONTINUOUS reads all cells every ~500ms.

COMMANDS NOT SUPPORTED (V05 VERSION):

SELFTEST

READ AUX

OPERATING THE CONTROL SCREEN

5. View the CSV file in a compatible spreadsheet software 

program such as MS Excel.

SOFTWARE ADJUSTMENTS

The GUI program can control up to ten boards on a stack. 
1.  Select the number of boards on the stack by sliding the track 

bar up or down; located at the bottom left of the screen.
