Procedure

The MAX6683 EV kit is fully assembled and tested.

Follow the steps below to verify board operation.

Caution: Do not turn on the power supplies until all

connections are completed.

1) Visit the Maxim website (www.maxim-ic.com/evkit-

software) to download the latest version of the EV

kit software, 6683Rxx.ZIP.

2) Install the MAX6683 EV kit software on your com-

puter by running the INSTALL.EXE program. The

program files are copied and icons are created in

the Windows Start menu.

3) Carefully connect the boards by aligning the 20-pin

connector of the MAX6683 EV kit with the 20-pin

header of the CMODUSB interface board. Gently

press them together.

4) Ensure that a shunt is on pins 1-2 of jumper JU4.

Do not turn on the power until all connections are

made.

5) Connect the 3.3V power supply to the VCC and

GND pads.

6) Connect the 1.8V nominal power supply to the 1.8

VIN and GND pads.

7) Connect the 2.5V nominal power supply to the 2.5

VIN and GND pads.

8) Connect the 5V nominal power supply to the 5 VIN

and GND pads.

9) Connect the USB cable from the PC to the

CMODUSB board. A Building Driver Database

window pops up in addition to a New Hardware

Found message. If you do not see a window that is

similar to the one described above after 30

seconds, remove the USB cable from the

CMODUSB and reconnect it. Administrator

privileges are required to install the USB device

driver on Windows 98SE/2000/XP. Refer to the

TROUBLESHOOTING_USB.PDF document in-

cluded with the software if you have any

problems during this step.

10) Follow the directions of the Add New Hardware

Wizard to install the USB device driver. Choose the

Search for the best driver for your device option.

Specify the location of the device driver to be

C:\Program Files\MAX6683 (or the directory cho-

sen during installation) using the Browse button.

11) Turn on the power supplies.

12) Turn on the EV kit by moving SW1 to the ON posi-

tion.

13) Start the MAX6683 EV kit software by clicking on its

icon in the Start menu.

14) Wait until the program automatically detects the

address of the MAX6683 and displays the user-

interface panel (Figure 1).

15) Select the Configuration tab on the panel (Figure

2). Uncheck the Interrupt Clear checkbox.

16) Check the START checkbox.

17) Verify that the internal temperature displayed on the

user-interface panel is not 0.000

°C.
