GENERAL DESCRIPTION
This user guide applies to the ADIS1650x IMU (Inertial
Measurement Units). The members of this family include the
ADIS16500, ADIS16505, and ADIS16507. Although only the
ADIS16505 is discussed within, this guide is applicable to all
members of the ADIS1650x family, as these devices differ
primarily performance levels and sensitivity ratings.
The ADIS16505 is a very small, high-performance. The
ADIS16505 features factory internal calibration, high
performance, and robust operation in dynamic and challenging
environments.
The ADIS16505 evaluation board, together with the EVAL-
ADIS2 are a compact, easy-to-use platform for evaluating all
features of the ADIS16505.

THE ADIS165505 BREAKOUT BOARD
Figure 2. ADIS16505-2/PCBZ
DESCRIPTION
Breakout boards provide a simple way to connect an existing
embedded processor platform to an ADIS16500, ADIS16505 or
ADIS16507 IMU. Each breakout board contains (1) IMU and a
simple interface connector, which provides access to all
necessary electrical connections with the IMU. Figure 2
provides a picture the ADIS16505-2/PCBZ breakout board,
which contains and ADIS16505-2BMLZ IMU model.
Table 1 provides a list of the model numbers for each breakout
board, along with the IMU model that is on each breakout
board.

DRAWING
Figure 3 provides a top-level view of the breakout board layout,
along with key physical attributes. The electrical interface (J1)
on each breakout board is a dual row, 2 mm pitch, 16-pin
interface. This supports standard ribbon cabling with 1 mm pitch.

PIN ASSIGNMENTS
Table 2 provides the J1 pin assignments which support direct
connection to an embedded processor board using standard
ribbon cables. Although each environment has its own
sensitivities (such as electromagnetic interference (EMI)), these
boards typically support reliable communication over ribbon
cables up to 20 cm in length.

EVALUATION USING THE EVAL-ADIS2 SYSTEM
Figure 5. EVAL-ADIS2 System Block Diagram
In addition to supporting quick prototype connections between the IMU and an embedded processing system, the breakout boards
connect directly to J1 on the EVAL-ADIS2 evaluation system. When used in conjunction with the IMU Evaluation Software for the EVAL-
ADISZ Platforms, the EVAL-ADIS2 provides a simple, functional test platform that allows users to configure and collect data from the
IMU models. Figure 5 and Figure 8
Important: Download and install USB drivers before connecting the EVAL-ADIS2 to the test computer.
USB DRIVER INSTALLATION
The following instructions cover the USB driver installation for
the EVAL-ADIS2, and is common to ADI IMU products.
1. Navigate to
ftp://ftp.analog.com/pub/IMU/IMU_FTP_Directory.htm.
2. Locate and click on the link called SDPDrivers.zip under
the heading of EVAL-ADIS2 USB drivers.
3. After downloading the EVAL-ADIS USB Driver file,
extract the SDPDrivers.exe file from the zip file and double
click on the EXE to start the process. When the setup
wizard opens, click on Next to start the installation process:
4. Click on Next to accept the default driver location.
5. The user will see at least two progress bars like this:

Rev. PR.C | Page 6 of 11
6. Click on Install to continue with the installation if this
message appears during the process:
7. Click Finish to complete the process.
DOWNLOADING THE EVALUATION SOFTWARE
The evaluation software for the ADIS16505 can be downloaded
from the ADI IMU ftp site
1. Navigate to the ftp site by clicking here:
ftp://ftp.analog.com/pub/IMU/IMU_FTP_Directory.htm
2. Click on “IMU Evaluation 1.18.xx” where “xx” is the latest
version posted on the FTP site.
After the EXE file downloads, place it in a convenient location
on the host PC, but don’t run it until the evaluation board is
connected to the PC.
Note: If the user runs the software before connecting the
evaluation board, the user will see the following pop-up
windows and errors:
If this occurs, the user should exit out of the software, and
proceed to the “EVAL-ADIS2 Physical Connections” section of
this user guide and ensure that the evaluation board is properly
connected and powered prior to running the evaluation
software.

EVAL-ADIS2 PHYSICAL CONNECTIONS
Figure 8 illustrates the physical connection between the
ADIS16505-2/PCBZ and an EVAL-ADIS2Z evaluation system.
Connecting the Evaluation Boards
1. Ensure that Jumper JP1 (See “DUT Supply Selection” in
Figure 6) is straddling the left “+3.3V REG” pin and the
center pin, assuming the EVAL-ADIS2 board is oriented as
shown in Figure 6.
Note: If the user wishes to use an external power supply,
move the JP1 jumper so that it straddles the center and
lower pin and connect the external supply to Connector J3.
GND is the left pin and VDD (+3.3 V) is the right pin.
See Figure 7 for an illustration.
2. Connect the ribbon cable between the EVAL-ADIS2 and
ADIS16505 evaluation board.
3. Connect the EVAL-ADIS2 USB cable to the PC and verify
that LED1 and LED2 are illuminated on the EVAL-ADIS2
board.

EVALUATION SOFTWARE
RUNNING THE EVALUATION SOFTWARE
1. Ensure the that USB Driver is properly installed as
described in the “USB Driver Installation” section of this
user’s guide.
2. Ensure that the evaluation board is properly connected as
described in the “EVAL-ADIS2 Physical Connections”
section of this user’s guide.
3. Double-click on the ADIS16505 evaluation software EXE
file. The user should click the “Run” button if this pop-up
window appears:
4. The EVAL-ADIS main window appears
5. On the Devices Menu, select the correct IMU model.
6. Click on the “READ” button to read the IMU registers in
real-time. If the EVAL-ADIS2 is correctly connected, and
all the drivers and software are correctly installed, the user
should see the following, if the IMU is at rest and lying
face-up on a flat surface:
Note that the gyroscopes read zero rotation, the x- and y-
axis accelerometers read 0 g, and the z-axis reads 1 g.

ADIS1650x/PCBZ User Guide UG-ADIS1650x
Rev. PR.C | Page 9 of 11
7. Movement of the IMU is recorded and displayed in real
time:
8. The user can change register settings by clicking on the
“Register Access” menu. In this example, the decimation
rate is being changed from 0x00 to 0x07.
9. Logging the IMU readings is a common task using the
EVAL-ADIS2 and clicking on the Data Capture menu
brings up the data capture window. This window allows the
user to choose which settings to log. Note that if a
decimation rate of 0 (no averaging) is used, the user will
need to select 16-bit gyro and accelerometer values (not
32-bit) to have enough time to transfer all data in one data
capture interval. However, this does not limit the accuracy
of the IMU data, as the lower 16-bits are only significant
when averaging or filtering is enabled.

TROUBLESHOOTING
RUNNING THE SOFTWARE WITHOUT AN EVAL-
ADIS2 EVALUATION BOARD ATTACHED
The user will see the following screens if the evaluation software
is run without the EVAL-ADIS2 connected:
In this case, the user should exit out of the software, and
proceed to the “EVAL-ADIS2 Physical Connections” section of
this user guide and ensure that the evaluation board is properly
connected and powered prior to running the evaluation
software.
DEVICE BLACKLISTED
The most common cause of this error is attempting to read the
registers of the IMU while the EVAL-ADIS2 evaluation board is
disconnected from the PC after having previously been
successfully connected. Communication can be restored by
reconnecting the EVAL-ADIS2 to the PC.
LOG FILE ERROR
This error occurs if the filename specified for the data log file
already exists. The user should either rename the existing file or
choose a different filename for the new log file.
