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.
A battery should be connected between the VDD (positive terminal) and VSS (negative terminal) and
provide enough voltage to power the DS2502. In order to program the device, a 12 Volt programming
voltage should be connected between VPP and VSS.
SOFTWARE INSTALLATION
To install the DS2502 EV kit software, download the latest version at www.maxim-ic.com. Unzip the
compressed file and double-click the SETUP.EXE icon to begin the installation process. Follow the
prompts to complete the installation. The DS2502 EV kit software can be uninstalled in the Add/Remove
Programs tool in the Control Panel. After the installation is complete, open the DS2502K folder and run
DS2502K.EXE or select DS2502K from the program menu. A splash screen containing information
about the evaluation kit appears as the program is being loaded.
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 DS2502 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 DS9123, click the Poll Ports button. Warning:
Automatically polling for the DS9123 can disrupt other devices connected to your computer’s COM
ports.
