MAX5474 Evaluation Kit

Quick Start

Recommended Equipment

Before beginning, the following equipment is needed:

• Maxim MAX5474 EV kit (USB cable included)

• User-supplied Windows 2000/XP/Vista-compatible

PC with a spare USB port

• One ohmmeter

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 operating

system.

Procedure

The EV kit is fully assembled and tested. Follow the

steps below to verify board operation. Caution: Do not

turn on the power supply until all connections are

completed.

1) Visit www.maxim-ic.com/evkitsoftware to download

the latest version of the EV kit software,

5474Rxx.ZIP. Save the EV kit software to a tempo-

rary folder and uncompress the ZIP file.

2) Install the EV kit software on the computer by run-

ning the INSTALL.EXE program inside the tempo-

rary folder. The program files are copied and icons

are created in the Windows Start | Programs

menu.

3) Verify that a shunt is installed on pins 1-2 of jumper

JU1. This configures the MAX5474 IC’s VDD to 3.3V

from the USB interface circuit.

4) Verify that a shunt is installed on pins 1-3 of

jumpers JU2, JU3, and JU4. This configures the

logic-input pins to receive signals from the USB

interface circuit.

5) Verify that no shunt is installed on jumpers JU5 and

JU6, the L PCB pad is not connected to GND, and

the H PCB pad is not connected to the W PCB pad.

6) Connect the ohmmeter across the W and L PCB

pads.

7) Connect the USB cable from the PC to the

MAX5474 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 recon-

nect it. Administrator privileges are required to

install the USB device driver on Windows

2000/XP/Vista.

8) 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\MAX5474 (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.

9) Start the MAX5474 EV kit software by opening its

icon in the Start | Programs menu.

10) The software automatically searches for the

MAX5474. After successful connection, the EV kit soft-

ware main window appears in the upper-left corner of

the window. Select the Up/Down buttons to change

the wiper position, or enter the desired wiper position

into the Wiper Input combo box (see Figure 1).

See the Detailed Description of Software section for

more information on the software features.
