SETUP AND INSTALLATION
BOARD CONNECTIONS
Connections to the TSSOP demonstration board are best made either by soldering directly to the pads or by using
cables with mini-grabber clips. Communication to the TSSOP board can be accomplished either through the RJ-11
jack by connecting the provided standard six conductor RJ-11 cord.
Figures 1a and 1b show the recommended circuits to simulate charging and discharging. The Li+ cell is connected
between the B+ and B- pads. The battery charger/power supply or circuit load is connected between the B+ and P-
pads. The evaluation software can be run in either configuration as long as a cell is connected between the B+ and
B- terminals providing a minimum of 2.5V to power the DS2786.
SOFTWARE INSTALLATION
To install the DS2786 EV kit software, exit all programs currently running and download the latest DS2786 EV kit
software from our website at www.maxim-ic.com. Unzip the compressed file and double click the SETUP.EXE icon
to being the installation process. Follow the prompts to complete the installation. The DS2786 EV kit software can
be uninstalled in the Add/Remove Programs tool in the Control Panel. After the installation is complete, open the
DS2786K folder and run DS2786K.EXE or select DS2786K from the program menu. A splash screen containing
information about the evaluation kit appears as the program is being loaded. All relevant data sheets and
application notes on the DS2786 and DS2786 EV kit can be found on our website at www.maxim-ic.com..
SELECTING THE COMMUNICATION PORT
The first time the software runs, the Select Preferences window may appear. In this window, select either serial
port or USB communication and the port number; then hit OK. The DS2786 EV kit software saves this port
selection and automatically uses the selection each time the program starts. To change the port later, click the
Preferences option on the menu bar, select Port Settings, and then select the appropriate port. To attempt to
automatically locate the DS9123O, click the Poll Ports button. Warning—automatically polling for the DS9123O can
disrupt other devices connected to your computer’s COM ports.
