1What you need

• EVAL-L9963-MCU

• USB cable

• Power supply (at least 3 output 0 – 30 V (if possible 60V):

– 1 output to power L9963 (0:60 V)

– 1 output to simulate Cells common mode voltage (0:60 V)

– 1 output to simulate Cell voltage (0:5 V)

• L9963 evaluation GUI STSW-L9963

• NI Labview-runtime 2014

• NI VISA-RUNTIME

Note: Before using the UART/USB bridge FT2232H, the Virtual Com Port (VCP D2XX) driver needs to be installed. It

can be downloaded by the FTDI Chip website.

Note: 1. EVAL-L9963-MCU can be considered the only stage or the first stage of several stages. The port is the

isolated vertical interface to the next stage (EVAL-L9963-NDS);

2. A second L9963T (optional) may be needed to create a direct loop with the last stage (dual ring access);

3. MCU can be supplied either by USB or by L9001 (PMIC);

4. On board MCU can be bypassed in case a different MCU is needed for the user trials; these pins allow

an SPI connection with an external MCU (upon a specific board configuration). Anyway a specific board

derivative of EVAL-L9963-MCU has been designed for this purpose (same form factor/layout with MCU not

mounted: EVAL- L9963).

8Preliminary action to open the GUI

Install the following SW on your PC:

• NI Labview-runtime 2014

• NI VISA-RUNTIME

• FTDI driver

– Before using the UART/USB bridge FT2232H, the Virtual Com Port (VCP) driver needs to be installed.

It can be downloaded by the FTDI Chip website.

When all is installed reboot your PC and open STSW-L9963.exe
