(a) Configure the EVM jumpers per
(b) Connect the EVM to the Power Supplies or cells, turn on the supplies at ~12-to-24 V is recommended.
The Absolute Maximum voltage per IC is 36 V and should not be exceeded, 30 V is the recommended
maximum continuous voltage.
(c) Connect the USB cable to the Aardvark and your PC.
(d) Connect the Aardvark ribbon cable to the 10-pin header on the EVM board.
(e) Start the WinGUI User Interface software supplied with the EVM and installed earlier.

Connection Notes
The ISO-COMMS section of the EVM board isolates the EVM side voltages completely from the PC side.
It isolates all power, ground, and signal lines to the EVM. Caution must still be taken when using the EVM
as part of a stack, where lethal voltages may be present. The galvanic isolation provided by the ISO-
COMMS section does not eliminate the need for safe handling procedures, proper High-Voltage
equipment, and protective clothing. Proper safety procedures should always be followed.
Because the ISO-COMMS circuit section fully isolates the PC, Aardvark, and wall adapter from the EVM
“battery” side, the Aardvark is insensitive to the powering of the EVM, which receives its power from the
battery cells or power supply used for evaluation.
The grounds (VSS) are fully isolated; please keep this in mind when using an oscilloscope or meter. Do
not inadvertently connect the EVM VSS to the PC/Aardvark VSS by connecting two probe grounds or
otherwise forming a ground loop through external wiring, including the building wiring.
