• Manufacturer Part Number: DS2705K
• Description: Power Management IC Development Tools
• Manufacturer: Maxim Integrated
• Series: DS2705r

Communication to the DS2705 with the DS2705 EV kit software can be accomplished through the RJ-11 jack
labeled as “SLAVE ”. Simply connect the provided standard six conductor RJ-11 cord from the “SLAVE ” jack
to the DS9123O USB Adapter. Then attach the VDD/VSS terminals to a battery or power supply and the DS2705
EV kit software can communicate with the DS2705 for programming and configuring the device.
The DS2705 can operate as a Master by connecting the RJ-11 jack labeled as “MASTER” to the RJ-11 jack of a
DS2703 EV Kit/DS2704 EV Kit with a RJ-11 cord. A DS2704 EV Kit will require a battery or power supply. A
DS2703 EV Kit can be connected without any additional connections.
A 15V programming voltage is required on the High Voltage (HV) terminal in order to store the Challenge,
Response and Configuration to EEPROM.
The Challenge (CH) terminal is used to initiate a SHA-1 Authentication.
SOFTWARE INSTALLATION
To install the DS2705 EV kit software, exit all programs currently running and download the latest DS2705 EV kit
software from our website at www.maxim-ic.com. Unzip the compressed file and run SETUP.EXE to begin the
installation process. Follow the prompts to complete the installation. The DS2705 EV kit software can be
uninstalled in the Add/Remove Programs tool in the Control Panel. After the installation is complete, open the
DS2705K folder and run DS2705K.EXE or select DS2705K from the program menu. A splash screen containing
information about the evaluation kit appears as the program is being loaded.
SELECTING THE COM PORT
If the DS9123O is connected when the DS2705 EV Kit is powered, the software will start up automatically. If it is
not connected, the Select Preferences window will open. This software will also operate with the DS9123 Serial
Port Adapter.
In this window, select either serial port or USB communication and the port number; then hit OK. The DS2705 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 Edit Preferences, and then select the
appropriate port. To attempt to automatically locate the DS9123O or DS9123, click the Poll Ports button. Warning -
automatically polling for the DS9123 can disrupt other devices connected to your computer’s COM ports.
MENUS
Several pull down menu options have been provided to simplify use of the DS2705 EV kit software for the user.
