MAX5432 Evaluation Kit
7) Connect the ohmmeter across the W and L PCB pads.
8) Connect the included USB cable from the PC to the
MAX5432 EV kit. A Building Driver Database win-
dow pops up in addition to a New Hardware Found
message when installing the USB driver for the first
time. If a window similar to the one described above
does not appear after 30s, remove the USB cable
from the board and reconnect it. Administrator privi-
leges are required to install the USB device driver
on Windows 2000/XP/Vista.
9) 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\MAX5432 (default installation
directory) using the Browse button. During device
driver installation, Windows may show a warning
message indicating that the device driver Maxim
uses does not contain a digital signature. This is not
an error condition and it is safe to proceed with
installation. Refer to the USB_Driver_Help.PDF doc-
ument for additional information.
10) Start the MAX5432 EV kit software by opening its
icon in the Start | Programs menu.
11) Observe as the program automatically detects the
address of the MAX5432 and starts the main pro-
gram. After successful connection, the EV kit soft-

ware main window appears in the upper-left corner
of the window.
12) The MAX5432 EV kit is ready for additional testing.
See the Detailed Description of Software section for
more information on the software features.
Detailed Description of Software
In the following sections, text in bold refers to items
directly from the EV kit software.
Graphical User Interface (GUI)
The MAX5432 EV kit software GUI (Figure 1) is a
Windows program that provides a convenient means to
control the MAX5432. Use the mouse or press the TAB
key to navigate through the GUI controls. The correct
I 2 C write operation is generated to update the
MAX5432 internal memory registers when any of these
controls are executed.
The software divides EV kit functions into logical blocks.
The Interface group box indicates the EV kit’s Status ,
Device Address , I 2 C Bus Speed , the last write opera-
tion Command Sent , and Data Sent indicators. This
data is used to confirm proper device operation. The
Potentiometer Control group box changes the wiper
position, stores the wiper position from the volatile
memory to the nonvolatile memory, and recalls the
wiper position from the nonvolatile memory to the
