2 / 10 page ________________________________________________________________________________________ Quick Start Recommended Equipment • DC power supply (3.3V @ 0.5A) • Stereo audio source (e.g., CD player, MP3 player, etc.) •32Ω or 16Ω headphones • MAX9723D EV system MAX9723D EV kit Maxim CMODUSB+ or CMOD232+ system command module • A user-supplied Windows 98SE/2000/XP PC Note: In the following sections, software-related items are identified by bolding. Text in bold refers to items directly from the EV kit software. Text in bold and underlined refers to items from the Windows 98SE/ 2000/XP operating system. Procedure Follow the steps below to verify board operation. Caution: Do not turn on the power supply until all con- nections are complete. 1) Visit the Maxim website (www.maxim-ic.com/evkit- software) to download the most recent version of the EV kit software, 9723RXX.ZIP. Save the EV kit software to a temporary folder and uncompress the ZIP file. 2) Install the MAX9723D EV kit software on your com- puter by running the INSTALL.EXE program inside the temporary folder. The program files are copied and icons are created in the Windows Start | Programs menu. 3) Carefully connect the system command module to the EV kit by aligning the 20-pin connector of the MAX9723D EV kit with the 20-pin header of the Maxim system command module interface board. 4) Enable the pullup resistors on the system command module by making sure the SDA switch and SCL switch (both on SW1) are thrown on. 5) If using Maxim’s serial-interface board (CMOD232+), connect a 9-pin male-to-female cable from the com- puter’s serial port to CMOD232+. CMOD232+ requires a 9V power supply to P1 (DC IN). For regu- lated 3.3V output voltage, install a shunt across pins 1-2 of J1 on the CMOD232+. If using Maxim’s USB interface board (CMODUSB+), connect the A-to-B USB cable from the computer’s USB port to CMODUSB+. CMODUSB+ requires no external power as it is powered from the PC USB port. For reg- ulated 3.3V output, install a shunt across pins 2-3 of J1 on the CMODUSB+. 6) Ensure that a shunt is placed across pins 1-2 of JU3 on the MAX9723D EV kit board.
