Orderable Part Numbers

•The EVAL-ADCM is an orderable kit that includes ADcmXL3021 module and all necessary

boards to interface with a PC.

•The EVAL-ADCM-1 is an orderable kit that includes ADcmXL1021-1 module and all

necessary boards to interface with a PC.

Note: EVAL-ADCM and EVAL-ADCM-1 are identical kits except for included ADcmXL modules.

As such, one can evaluate both ADcmXL3021 and ADcmXL1021-1 using EVAL-ADCM (or EVAL-

ADCM-1) provided that an ADcmXL1021-1 (or ADcmXL3021) module is ordered separately.

Minimum PC System Requirements

•Windows XP, Vista, 7 or 10

•.NET Framework 4.5

Minimum Required Hardware

•Cypress Semiconductor EZ-USB® FX3 Development Kit (with included USB3.0 A to B

cable), shown in Figure 1.

•ADCMXL_BRKOUT/PCBZ, shown in Figure 2.

•ADcmXL FX3 Interface board, shown in Figure 3

•ADcmXL device, shown in Figure 4.

EVAL-ADCM Hardware Setup

Figure 6 Hardware included with EVAL-ADCM (or EVAL-ADCM-1) kit. Not shown are 8

mounting screws, short ribbon cable option and an ADcmXL3021 (or ADcmXL1021-1)

device.

Step 1

Plug in the ADcmXL FX3 Interface Board to the Cypress FX3 Evaluation Board.

Figure 7 Pin 3 on both J1 and J2 should be cut.

Note: On the ADcmXL FX3 Interface Board, the 2 connectors that interface to FX3 board must

have Pin 3 on both headers cut. If not already snipped, these pins must be cut or bent out of the

way otherwise the FX3 board will not plug in together as these pins are keyed on the FX3 Board.

Step 2

Connect the FX3 and ADcmXL FX3 Interface Board together and connect additional 2 jumpers

for the Cypress FX3 Evaluation Kit. (There are 4 jumpers in total and all should be placed on the

FX3 board as shown in the figure below).

Figure 8 All four jumpers should be connected.

Step 3

Connect either available ribbon cables (short or long) from J5 of the ADcmXL FX3 Interface Board

to the pre-assembled ADcmXL3021 (or ADcmXL1021-1) and the ADCMXL_BRKOUT/PCBZ.

Note 1: The shorter ribbon cable (2”) is required for RTS Mode but may be used in any of the

operation mode. The longer ribbon cable is provided for easier handling and in situ measurements

but could result in packet errors when operating in RTS mode. The longer ribbon cable is best of

MTC, AFFT and MFFT modes of operation.

with respect to the board.

Note 2: ADcmXL module and the ADCMXL_BRKOUT/PCBZ are pre-assembled (both secured to

the acrylic plate) to reduce possible stresses on the Flex tail. Depending on the application, the

ADcmXL module and the ADCMXL_BRKOUT/PCBZ can be unmounted from the plate and be

secured to the platform of choice.

Step 4

Connect the FX3 Evaluation Board to the PC with the ADCMXL Evaluation Software using the

provided USB3.0 cable that is shipped with the Cypress FX3 Evaluation kit box.

Software Installation

In order to use the ADCMXL Evaluation Software, FX3 Driver needs to be downloaded and

installed before ADCMXL Evaluation Software. Follow the steps below:

1. Un-compress the file FX3Driver.zip from the Wiki page.

(Note: The FX3 board will have driver software available on Cypress website or other

platforms, that may be different than the one provided on ADI’s wiki page. The driver

provided is the one tested with the ADcmXL Evaluation Software and in some cases other

drivers may not be supported.)

2. Run the executable DriverSetup.exe

3. Connect the ADCMXL3021 (or ADcmXL1021-1) device, breakout boards, and the FX3

through the interface board.

4. Connect the FX3 board to a PC USB port. LED indicates power. One LED on the FX3

board and one on the BR-047904 adapter board should be lit by default when the USB

cable is plugged into the PC

5. Run the application ADCMXL_Evaluation_n_n_n.exe. Note: This application and the

required DLLs must be in the same folder.

Troubleshooting

No light on the ADCMXL_BRKOUT/PCBZ board are lit:

-Check to make sure the ADcmXL module is plugged into P2.

-Check that ribbon cable is firmly and correctly plugged into both boards.

-Check that USB is plugged into the FX3 board, the FX3 board is plugged into the ADcmXL

FX3 Interface board.

More or less than 1 LED is lit on the FX3 board

-Check that the USB 3.0 A to B cable is plugged into the PC and the FX3 board.

-Use a different USB port on the PC.

-Be sure 4 jumpers are placed on the FX3 board.

When running software, get a message similar to “Unable to connect to an FX3 Board”

-Be sure ADcmXL Evaluation software is in a folder with all provided .dll files

-FX3 driver not installed properly or at all, Install provided FX3 driver

-Unplug and re-plug USB cable to power cycle the FX3 board

Verifying the USB Connection

Before starting the ADcmXL Evaluation Software, when the Cypress FX3 board is connected it

should be listed in Universal Serial Bus controllers as “Cypress FX3 USB BootLaoder Device”.

This is confirmation that the Cypress USB drivers have been installed. When the ADcmXL

Evaluation Software application is started the device should reconnect as an “Analog Devices

iSensor FX3 Demonstration Platform”.

Application Functional Overview and User Guide

Devices

Select the product, either ADcmXL1021-1 or ADcmXL3021. Note that once ADcmXL1021-1 is

selected, some of the features relating to 3-axis is disabled.

Provides an interface for reading andwriting the registers of the device. The leftside panel shows

Registers grouped into Categories: Control/Status, Output, Calibration and Filter Bank. The panel

on the right displays the bit fields of a selected control register selected from the pull down menu

at the top. The center of the window provides access to read and write registers and allows the

saving of registers to a file and loading register settings from a file.

RegDump.csv file. Press Open. The values will be written to the registers of the ADCMXL

device.

Alarms

Alarm Values Form

Allows for the entry of Alarm frequency band values for each of the six bands and four Sample

Rate Options. Default values are stored in the application. Alarms must be enabled by setting

values in the ALM_CTRL register available in the Register Access Form. Alarm values can be

saved in non-volatile memory of the DUT by accessing the Command register available in the

Figure 12 Alarm Values Form, the default values are loaded from the nonvolatile memory of the DUT.

Alarm Status Form

Displays the alarm status for the current capture. Alarm band line values are shown on FFT plots

if the Alarm Status Form is visible.

and press save. The displayed table values will be saved to a file.

Checking Alarm Status

1. Open Alarm Values Window by selecting “Alarm” on the top bar of the Evaluation Software

window and then “Alarm Status”, which will open a new window.

2. The Alarm Status Window will display the current state of the 6 configurable alarms across

the 3 different axes.

Example: In the example below, the Y and Z axis alarms are enabled, however, X -axis is not

enabled. Note that the Alarm Status form shows normal (0) for X-axis, while the in five out of six

bands the alarm should have been raised.

Figure 14 Alarm band lines and Alarm Status form (overlay) shown in an example vibration measurement. X-axis

alarm is disabled.

Data Capture

The user can configure where the files to be stored and reset the file count. To set the Data

Capture options, open the Data Capture Configuration dialog window by selecting “Data Capture”
