1 Introduction
The ZSSC5101 Evaluation Kit enables evaluation of the ZSSC5101 xMR Sensor Signal Conditioner IC, which is
designed for interfacing with magnetoresistive position sensors. The ZSSC5101 AMR Demo Board included in the
kit provides a typical anisotropic magnetoresistive (AMR) position sensor for demonstrating typical calibration
procedures and reading example measurement results. Alternatively, the user module can be connected in place
of the AMR Demo Board (e.g., with a tunnel magnetoresistive (TMR) or giant magnetoresistive (GMR) sensor).
This document describes the kit including hardware and software setup and basic operations.
Note: Reading the ZSSC5101 Data Sheet before using the kit is strongly recommended.

1.2. Downloading the Evaluation Kit Software
To ensure use of the latest version ZSSC5101 Evaluation Software, the software must be downloaded as a zip
file from the ZSSC5101 product web page at www.zmdi.com/zssc5101. Alternately, the software can be
requested through the ZMDI application support team (see page 25 for contact information).
Requirements for user’s computer:
Windows®-based operating system
An available USB port
Administrative rights for installing the software and if needed, installing the driver for the SSC
Communication Board (SSC CB)
A free customer login account is required to access the software on the product page. To set up an account, visit
www.zmdi.com and click on Login in the upper right corner of the page. Follow the instructions in the resulting
dialog box to setup a user name and password. Then log in to the account.
To download the zip file, navigate to the product page and click on the heading SOFTWARE. In the resulting
drop-down menu, click the link titled ZSSC5101 Evaluation Kit Software Rev. X.yy where X.yy refers to the
current version number. Save the downloaded zip file to a user-selected location on the computer and extract the
contents of the zip file.
Contents of the zip file:
Documentation directory, which provides useful supporting documents
UsbDriver directory, which provides the required hardware driver for the SSC Communication Board (see
section 3.1 for further details)
ZSSC5101_GUI directory, which contains the graphical user interface (GUI) and its associated files (see
section 3.2 for further details)

2 Hardware Setup
Before proceeding with the software setup, assemble the ZSSC5101 Evaluation Kit as shown in Figure 2.1 and
connect a USB cable from the connector on the SSC CB to an available USB port on the user’s computer.
Note that up to two ZSSC5101 AMR Demo Boards can be connected at the same time (via the Module 1 and
Module 2 connectors on the ZSSC5101 Adaptor Board). Additional AMR Demo Boards are sold separately.
Important: Before unplugging any ZSSC5101 module during operation, always click the “Power OFF”button in the
software first (see section 4).

3 Software Setup
3.1. ZMDI Communication Board Driver Installation
The SSC Communication Board converts the USB bus protocol to a serial data interface for communication
between the user’s computer and the ZSSC5101. A special driver (FTDI) must be installed.
Before continuing, ensure that the ZSSC5101 Evaluation Kit is connected via a USB cable to the user’s computer
as described in section 2.
3.1.1. Compatibility Check
The following procedures are used to determine if the correct driver is already installed on the computer by
checking the Device Manager in the Windows®Control panel.
1. Navigate as needed to the computer’s Control Panel → System and Security → Device Manager.
2. Scroll down the device list to the “Universal Serial Bus controllers” section and check for an entry titled
“USB Serial Converter.” If found, right click on it and select “Properties” from the resulting drop-down
menu.
3. If the “Manufacturer” is shown as “FTDI” as shown in the example in Figure 3.1, then the required driver is
already installed. In this case, skip the following steps and continue at section 3.2.
Figure 3.1 Example of Properties for a USB Serial Converter under the Device Manager
4. If the “Manufacturer” is not shown as “FTDI” or if “USB Serial Converter” does not appear in the Device
Manager list, the FTDI driver must be manually installed on the SSC Communication Board
microprocessor. If there is no driver installed for the SSC Communication Board, the device is likely to be
listed under “Other devices” as “FT232R USB UART” in the Device Manager list as shown in Figure 3.2.
Right click on the device and select “Update Driver Software.”

5. Next, select the option to manually browse for a driver:
6. Navigate to the UsbDriver subdirectory under the user-selected directory for the downloaded ZSSC5101
Evaluation Software. Select the CDM…..-Certified subdirectory as shown in Figure 3.3. Click the “OK”
button. Windows® automatically installs the FTDI driver software.

7. When the driver installation is complete, verify that message shown in Figure 3.4 is displayed and that the
SSC Communication Board is now listed as “USB Serial Converter” under “Universal Serial Bus
Controllers” in the Device Manager list as shown in Figure 3.1. If properly installed, proceed with the
steps in section 3.2 to activate the ZSSC5101 Evaluation Software.

3.2. Starting the ZSSC5101 Evaluation Software
After the FTDI driver is installed on the SSC Communication Board, the ZSSC5101 Evaluation Software is ready
to use without any additional installation. The software provides a graphical user interface (GUI) for communi-
cation and programming of the ZSSC5101. To start the GUI, go to the ZSSC5101_GUI subdirectory and click on
the ZSSC5101_GUI.exe file to run the software.
Figure 3.5 Location of the ZSSC5101 Evaluation Software
The GUI will open on the default screen shown in Figure 4.1. Typically the SSC Communication Board is detected
automatically. If not, click the “Find Comm” button as needed to connect.
