Quick Start

Recommended Equipment

• Windows 98/2000/XP computer and a USB port

• USB cable (to connect the computer’s USB port to

the CMODUSB command module)

• 5V/100mA DC power supply

•Ohmmeter

Procedure

The MAX5417L EV kit is fully assembled and tested.

Follow the steps below to verify board operation. Do

not turn on the power supply until all connections

are completed:

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

connector (J1) of the MAX5417L EV kit with the P3

20-pin header on the CMODUSB command mod-

ule. Gently press them together.

2) Slide both CMODUSB command module SW1 dip

switches to the ON position. Ensure that jumper J1

is installed in position 1-2, setting the command

module for 5V operation.

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

jumper JU1 (device address = 0x52) on the

MAX5417L EV kit.

4) Verify that a shunt is not installed on jumper JU3 on

the MAX5417L EV kit.

5) Use the INSTALL.EXE program on the provided

CD-ROM to copy the files and create icons in the

Windows 98/2000/XP Start menu.

6) Connect the 5V DC power supply to the VDD and

GND pads on the MAX5417L EV kit board.

7) Connect the ohmmeter across the L and W pads.

8) Turn on the power supply.

9) Connect a USB cable from the computer’s USB port

to the CMODUSB command module. Note: Do not

connect a power source to the P1 connector on the

command module. The command module is pow-

ered through the USB port.

10) Start the MAX5417L program by opening its icon in

the Start menu.

11) Observe as the program automatically detects the

address of the MAX5417L and starts the main program.

12) The MAX5417L EV kit is ready for additional testing.

Detailed Description

of Hardware

The MAX5417L EV kit is an assembled and tested PC

board that evaluates the MAX5417L linear-taper digital

potentiometer. The MAX5417L has an end-to-end resis-

potentiometer wiper among 256 tap positions. The

MAX5417L features an internal nonvolatile memory

(EEPROM) used to store the wiper position for initializa-

face can communicate at rates up to 400kbps to

program the nonvolatile and the volatile memory of the

MAX5417L.

The MAX5417L is programmed with a factory-preset

address and features a configurable address bit, A0,

which can set the device address to one of two unique

address combinations. The MAX5417L EV kit can also

be used to evaluate other 50kΩ digital potentiometers

(MAX5417M/N/P), each with their own unique factory

address. To evaluate the four versions of the MAX5418

(100kΩ) or the four versions of the MAX5419 (200kΩ)

digital potentiometers, IC replacement is required.
