EVALUATION BOARD HARDWARE
POWER SUPPLIES
When using the EVAL-AD2S1210 with the EVAL-CED1Z, all
supplies are provided from the controller board through the
96-way connector.
When using the EVAL-AD2S1210 board as a standalone unit,
external supplies must be provided. This evaluation board has
the following six power supply inputs:
• AVDD
• DVDD
• VDRIVE
• +12 V
• AGND
• DGND
If the evaluation board is used in standalone mode, 5 V must be
connected to the AVDD input to supply the AD2S1210 AVDD pin. In
addition, 5 V must be connected to the DVDD input to supply
the AD2S1210 DVDD pin, the PI74ALVTC16245AE, and the
74HC573. To supply the AD8664 quad op amp, 12 V should be
used. Lastly, 0 V is connected to one or both of the AGND
inputs and to the DGND input.
The AVDD, DVDD and VDRIVE supplies are decoupled to the
relevant ground plane with 4.7 μF tantalum and 0.01 μF multi-
layer ceramic capacitors. The AD8664, the PI74ALVTC16245AE,
and the 74HC573 are decoupled to the relevant ground plane
with 10 μF tantalum and 0.1 μF multilayer ceramic capacitors.
Extensive ground planes are used on this board to minimize
the effect of high frequency noise interference. There are two
ground planes, AGND and DGND. These are connected at one
location close to the AD2S1210.

SETUP CONDITIONS
Take care before applying power and signals to the evaluation
board to ensure that all link positions are set according to the
required operating mode. There are two different modes in which
to operate the evaluation board. Either the user can operate the
board with the EVAL-CED1Z or it can be used as a standalone
board. Table 2 shows the position in which all the links are set
when the evaluation board is packaged. When the board is
shipped, the assumption is that the user will be operating with
the EVAL-CED1Z. The links are set so that all power supplies
and control signals are supplied by the EVAL-CED1Z.
INTERFACING THE EVALUATION BOARD TO THE
EVAL-CED1Z
Interfacing the EVAL-CED1Z to the evaluation board is via a
96-way connector, J1. The pinout for the J1 connector is shown
in Figure 2. Table 3 gives a description of the pins on the 96-way
connector that are used to interface the EVAL-CED1Z board to
the EVAL-AD2S1210. Table 4 gives the pin designations for the
96-way connector.

OPERATING WITH THE EVAL-CED1Z
The evaluation board can be operated in a standalone mode or
operated in conjunction with the EVAL-CED1Z. This evaluation
board controller is available from Analog Devices under the
order entry EVAL-CED1Z.
When interfacing the EVAL-AD2S1210 directly to the EVAL-
CED1Z, all supplies and control signals to operate the AD2S1210
evaluation board are provided by the EVAL-CED1Z.
Software to communicate between the EVAL-CED1Z and
AD2S1210 is provided with the AD2S1210 evaluation board
package.
The 96-way connector on the EVAL-AD2S1210 plugs directly
into the 96-way connector on the EVAL-CED1Z. The EVAL-
CED1Z provides all the supplies for the evaluation board. It is
powered from a 7 V, 15 W power supply that accepts input
voltages from 100 V to 240 V ac and contains the relevant
adaptors for worldwide use. The power supply is provided with
the EVAL-CED1Z.
Connection between the EVAL-CED1Z and the USB port of a
PC is via a standard USB 2.0 connection cable that is provided
as part of the EVAL-CED1Z package.
INTERFACING TO THE EVALUATION BOARD IN
STANDALONE OPERATION
Options for interfacing with the evaluation board are via J4, a
26-way connector, via J20, a 10-way connector, or via external
Socket J8 to Socket J19. These connectors and sockets are provided
to allow the evaluation board to be interfaced with systems other
than the Analog Devices EVAL-CED1Z. The 26-way connector,
J4, is provided for use in parallel mode. The 10-way connector,
J20, is provided for use in serial mode. The pin designations for
both J4 and J20 are shown in Table 5 and Table 6, respectively.

EVALUATION BOARD SOFTWARE
INSTALLING THE SOFTWARE
The EVAL-AD2S1210 evaluation kit includes self-installing
software on a CD-ROM for controlling and evaluating the
performance of the AD2S1210 when it is operated with the
EVAL-CED1Z. The software is compatible with Windows®
2000/XP®. If the setup file does not run automatically,
setup.exe can be run from the CD-ROM.
When the CD is inserted into the PC, an installation program
automatically begins. This program installs the evaluation
software. The user interface on the PC is a dedicated program
written especially for the AD2S1210 when operating with the
EVAL-CED1Z.
Install the software before connecting the USB cable between the
EVAL-CED1Z and the PC. This ensures that the appropriate
USB driver files have been properly installed before the EVAL-
CED1Z is connected to the PC.
When the software is run for the first time with the EVAL-CED1Z
connected to the PC, the PC automatically finds the new device
and identifies it. Follow the onscreen instructions that appear
automatically. This installs the drivers for the EVAL-CED1Z on
the PC. If an error appears on screen when the software is first
opened, then the PC is not recognizing the USB device. To
correct this error,
1. Right-click the My Computer icon, then select Properties.
When the System Properties window opens, select the
Hardware tab.
2. Click Device Manager in the Hardware tab of the System
Properties window.
3. Examine the devices listed under the Universal Serial Bus
Controller heading.
4. If an unknown device is listed, right-click this option and
select Update Driver.
5. The New Hardware Wizard runs twice, and under the
ADI Development Tools, the hardware is listed as ADI
Converter Evaluation and Development Board (WF).
6. Reboot your PC.
SETTING UP THE EVAL-CED1Z
This section describes how the evaluation board, the EVAL-
CED1Z, and the software should be set up to begin using the
complete system.
1. Install the AD2S1210 evaluation board software.
2. Connect the EVAL-CED1Z and the evaluation board
together via the 96-way connector. Apply power to the
EVAL-CED1Z via the provided +7 V, 15 W power supply.
At this stage, the green Power LED on the EVAL-CED1Z
should light up, which indicates that the EVAL-CED1Z is
receiving power
3. The USB cable can then be connected between the PC and
the EVAL-CED1Z. A green LED positioned beside the USB
connector on the EVAL-CED1Z lights up indicating that
the USB connection has been established. The EVAL-CED1Z
is detected.
4. Proceed through any dialog boxes that may appear (use
the recommended options) to finalize the installation.
5. Start the EVAL-AD2S1210 software. The FPGA code is
automatically downloaded to the EVAL-CED1Z. The red
LED, D14, on the EVAL-CED1Z now lights up. This
indicates that the EVAL-CED1Z is functional and ready to
receive instructions.
The software can now be operated as described in the following
sections.
Note that when completing conversions on the AD2S1210
evaluation board while using the EVAL-CED1Z board, D14, the
red LED on the EVAL-CED1Z, lights up to indicate that the
USB transmission is occurring.

SOFTWARE OPERATION
With the hardware set up, you can now use the software to control
the EVAL-CED1Z and the AD2S1210 evaluation board. To
launch the software, from the Analog Devices menu, select the
AD2S1210 Evaluation Software submenu, and then AD2S1210
Ver0 . Figure 3 displays the main window that is opened. If an error
message appears, click Continue and restart the application after
checking the connection between the adapter board and the USB
port on the PC. Also check that the USB device is identified by the
Device Manager as detailed in the Installing the Software section.
The software that controls the EVAL-CED1Z and, therefore, the
AD2S1210 evaluation board, has one main window. Figure 3
shows the window that appears when the software is run. The
main function of this window is to allow you to read samples
from the evaluation board and display them. The window can
be divided into three main sections.
The menu bar is located at the top of the window. The control
buttons are below the menu bar, followed by a data capture
display.
The data capture display section consists of the following subtabs:
• Acquisition (Codes)
• Acquisition (Degrees/RPS)
• Stream (Codes)
• Stream (Degrees/RPS)
• Histogram Position
• Histogram Velocity
Note that the AD2S1210 evaluation software has two modes of
operation, normal mode and stream mode. In normal mode,
the software is designed to gather a defined number of samples
and display those results on the data capture display. In stream
mode, the software is designed to continuously sample the
AD2S1210 in defined measurement intervals, and display
the results as a continuous stream of data on the data capture
display. The Acquisition (Codes), Acquisition (Degrees/RPS),
Histogram Position, and Histogram Velocity tabs operate in
normal mode. The Stream (Codes) and Stream (Degrees/RPS)
tabs operate in stream mode. These modes of operation are
outlined in more detail in the Taking Samples section.

Fault Register. This indicator combines the fault register
information from each sample gathered during a single
acquisition sequence.
ON/OFF. Enables or disables the histogram option. (This button
appears on the Histogram Position and Histogram Velocity
tabs only.)
This section also includes a CED Buffer indicator that is relevant
only in stream mode. The AD2S1210 evaluation board allows
conversion to be initiated at periodic intervals. The default
conversion loop interval is 2 μs but can be increased up to
500 μs through the Sample Interval (μs) box. The AD2S1210
evaluation software and hardware is designed such that all
conversion results are written to external memory on the
EVAL-CED1Z, and blocks of samples are then uploaded
through the USB port to the PC. The CED Buffer indicator
provides an indication of the available memory remaining. If
there is increased activity on the USB port, the transfer of data
may be slowed down, which may cause the external memory to
fill before the data can be uploaded to the PC. In this case, the
CED Buffer indicator shows that the buffer is full. You should
either disconnect other external devices that may be using the
USB port, or you can increase the conversion loop interval to
decrease the number of samples to upload, which eases the
requirement on the USB port. Note also that the transfer of data
from the EVAL-CED1Z to the PC is slower when connected to
a USB 1.1 port than when connected to a USB 2.0 port.
Data Capture Display
In the data capture display, you can select the format in which to
view the position and velocity conversion results. The position
data can be displayed in digital output code format or in degrees.
The velocity data can be displayed in digital output code format
or in rotations per second (RPS). The desired display options are
selected by clicking on the Acquisition (Codes), Acquisition
(Degrees/RPS), Stream (Codes), Stream (Degrees/RPS),
Histogram Position, and Histogram Velocity tabs.
Acquisition (Codes) Tab
The Acquisition (Codes) tab displays the conversion results
taken in normal mode of the position and velocity of the resolver
connected to the AD2S1210 evaluation board. The number of
conversions results displayed is defined by the Num Samples
box. The conversion results are displayed as waveforms in
digital code on two graphs. The upper graph displays the posi-
tion conversion results. The lower graph displays the velocity
conversion results. The maximum, minimum, and mean values
of the sample set are displayed on indicators to the right of
each graph.
At the bottom right of each graph are the zoom options. These
allow you to zoom in and out to obtain a closer look at a sample
if required.
Acquisition (Degrees/RPS) Tab
The Acquisition (Degrees/RPS) tab displays the conversion
results taken in normal mode of the position and velocity of
the resolver connected to the AD2S1210 evaluation board. The
number of conversions results displayed is defined by the Num
Samples box. The position conversion result is displayed in
degrees on the upper graph. The lower graph displays the velocity
conversion results in RPS. The maximum, minimum, and mean
values of the sample set are displayed on indicators to the right
of each graph.
At the bottom right of each graph are the zoom options. These
allow you to zoom in and out to obtain a closer look at a sample
if required.
Stream (Codes) Tab
The Stream (Codes) tab displays the conversion results taken
in stream mode of the position and velocity of the resolver

Stream (Degrees/RPS) Tab
The Stream (Degrees/RPS) tab displays the conversion results
taken in stream mode of the position and velocity of the resolver
connected to the AD2S1210 evaluation board. The position
conversion result is displayed in degrees on the upper graph.
The lower graph displays the velocity conversion results in RPS.
At the bottom right of each graph are the zoom options. These
allow you to zoom in and out to obtain a closer look at a sample
if required.
Histogram Position Tab
The Histogram Position tab displays the histogram of the posi-
tion conversion results taken in normal mode of the resolver
connected to the AD2S1210 evaluation board. To enable this
option, you must set the ON/OFF button to the on position.
The histogram is displayed only when the output code varies for
the one block of samples; that is, if the same conversion result is
returned for all samples, the histogram is not displayed.
At the bottom right of each graph are the zoom options. These
allow you to zoom in and out to obtain a closer look at a sample
if required.
Histogram Velocity Tab
The Histogram Velocity tab displays the histogram of the velocity
conversion results taken in normal mode of the resolver con-
nected to the AD2S1210 evaluation board. To enable this
option, you must set the ON/OFF button to the on position.
The histogram is displayed only when the output code varies for
the one block of samples; that is, if the same conversion result is
returned for all samples, the histogram is not displayed.
At the bottom left of each graph are the zoom options. These
allow you to zoom in and out to obtain a closer look at a sample
if required.
TAKING SAMPLES
Initiating Conversions on the AD2S1210 Evaluation
Board
To initiate conversions and to capture the sample data, you must
click the Single Acquisition, Reoccurring Acquisition, or
Continuous Stream button.
When the Single Acquisition or Reoccurring Acquisition
button is clicked, the AD2S1210 evaluation software takes
samples in normal mode. When the Continuous Stream button
is clicked, the AD2S1210 evaluation software takes samples in
stream mode.
When the Single Acquisition button is clicked, the software
instructs the EVAL-CED1Z to read back the conversion results
from the AD2S1210 evaluation board. The number of samples
is selected via the Num Samples box. After each conversion,
data from the AD2S1210 is written to external memory on the
EVAL-CED1Z. The required set of samples is uploaded through
the USB port to the PC when the all conversions are completed.
When you click the Reoccurring Acquisition button, the software
instructs the EVAL-CED1Z to read back the conversion results
from the AD2S1210 evaluation board in a repeating loop. The
number of samples is selected via the Num Samples box. After
each conversion, data from the AD2S1210 is written to external
memory on the EVAL-CED1Z. The required set of samples is
uploaded through the USB port to the PC when all the conver-
sions are completed. If the Reoccurring Acquisition button is
not clicked again to release the loop, the conversion loop repeats.
While the data is being uploaded to the PC, the AD2S1210 device
is not converting; therefore, there is a time delay between two
blocks of samples.
When the Continuous Stream button is clicked, the software
instructs the EVAL-CED1Z to read back the conversion results
from the AD2S1210 evaluation board. After each conversion,
data from the AD2S1210 is written to external memory on the
EVAL-CED1Z. At regular intervals, blocks of samples results are
uploaded through the USB port to the PC. In Continuous Stream
mode, while the data are uploaded to the PC, the AD2S1210
device is still converting. Therefore, there is no additional time
delay between samples.
In single acquisition, reoccurring acquisition, and continuous
stream mode, the data is displayed on the data capture display.
When the Single Acquisition or the Reoccurring Acquisition
button is clicked, the data is displayed on the Acquisition
(Codes), Acquisition (Degrees/RPS), Histogram Position,
and Histogram Velocity tabs only. When the user clicks the
Continuous Stream button, the data is displayed on the Stream
(Codes) and Stream (Degrees/RPS) tabs only.

READING FROM AND WRITING TO REGISTERS ON
THE AD2S1210
To read from and write to the registers on the AD2S1210, click
the Registers button (see Figure 3). When you click the Registers
button, the software instructs the EVAL-CED1Z to read the
data in the AD2S1210 registers and displays this information in
another window (see Figure 4). The register data is presented in
decimal format. All registers are displayed on the right side of
the window.
To change the settings of any displayed register other than the
control register, you must overwrite the displayed decimal value
by typing or selecting the new value, and then click the Send
button. To overwrite the control register, use the four drop-
down boxes on the left side of the window.
Resolution. Selects the software resolution of the RDC in the
control register. This value must match the hardware resolution
set by the Resolution : 10/12/14/16 bits drop-down box on the
main window (see Figure 3).
Hysteresis. Enables or disables the hysteresis features of the
AD2S1210.
Phase Lock Range. Selects one of two phase lock ranges of the
AD2S1210.
Encoder Resolution. Selects the encoder resolution of the
AD2S1210.
Actual value sent to Control Register. Indicates the value that
is written to the control register after clicking the Send button.
Note that one or all of the registers can be written to with a
single update.
If you do not want to send any data to the registers, click the
Cancel button.
