MAX14820 Evaluation Kit
General Description
The MAX14820 evaluation kit (EV kit) consists of a
MAX14820 evaluation board and software. The EV kit is a
fully assembled and tested circuit board that evaluates the
Features
● IO-Link-Compliant Device Transceiver
● IO and SPI™ Interface Terminals
● Windows XP, Windows Vista, and Windows
®
MAX14820 and MAX14821 IO-Link device transceivers.
7-Compatible Software
®
®
The EV kit includes Windows XP , Windows Vista , and
● USB-PC Connection (Cable Included)
● Proven PCB Layout
®
Windows 7-compatible software that provides a graphi-
cal user interface (GUI) for exercising the features of the
two devices. The EV kit is connected to a PC through a
USB A-to-B cable.
● Fully Assembled and Tested

6) Start the EV kit software by opening its icon in the
Windows Start | Programs menu. The EV kit software
main window appears, as shown in Figure 1.

Recommended Equipment
•
MAX14820 EV kit (USB A-to-B cable included)
7) Verify that Hardware: Connected is displayed on the
•
User-supplied Windows XP, Windows Vista, or
Windows 7 PC with a spare USB port
status bar at the bottom of the main window.
8) Press the Read or Write buttons on the GUI to access

the device SPI registers.
Note: In the following sections, software-related items are
identified by bolding. Text in bold refers to items directly
from the EV kit software. Text in bold and underlined
refers to items from the Windows operating system.
Detailed Description of Software
The main window of the evaluation software (Figure 1)
displays the SPI registers and the device pins that are
connected to the on-board MAXQ2000 microcontroller.
The user can send read or write SPI commands to the
device, configure the logic levels of the device input pins,
and read back the logic levels of the device output pins.
Procedure
The EV kit is fully assembled and tested. Follow the steps
below to verify board operation before exercising the full
features of the device:
To read an SPI register or an output pin logic level, press
1) Visit www.maximintegrated.com/evkitsoftware to
download the latest version of the EV kit software,
14820Rxx.ZIP. Save the EV kit software to a tempo-
rary folder and uncompress the ZIP file.
the Read button.
To configure an SPI register or an input pin logic level,
first click on the desired radio button(s), and then press
the Write button.
2) Install the EV kit software and USB driver on your
computer by running the INSTALL.EXE program inside
the temporary folder. The program files are copied to
your PC and icons are created in the Windows Start
| Programs menu. During software installation, some
versions of Windows may show a warning message
indicating that this software is from an unknown pub-
lisher. This is not an error condition and it is safe to
proceed with installation. Administrator privileges are
required to install the USB device driver on Windows.
The software also automatically monitors the presence of
the wake-up pulse on the WU pin and displays the result
on the GUI.
The user can also change the SPI clock speed by clicking
on the desired SPI Clock Speed radio button.
Advanced User Interface
There are two methods for communicating with the
device. The first is through the window shown in Figure 1.
The second is through the Advanced User Interface win-
dow shown in Figure 2. The Advanced User Interface
window becomes available by selecting the Options |
Interface (Advanced User) menu item and allows execu-
tion of serial commands manually.
3) Verify that all the jumpers are in their default positions,
as shown in Table 1.
4) Connect the 24V DC power supply on the VCC and
GND connectors on the EV kit board.
The Advanced User Interface window can also be used
as a debug tool because it is capable of manually reading
and writing to every register and logic pin of the device.
5) Connect the USB cable from the PC to the EV kit
board. A Windows message appears when connect-
ing the EV kit board to the PC for the first time. Each
version of Windows has a slightly different message.
If you see a Windows message stating ready to use,
then proceed to the next step. Otherwise, open the
USB_Driver_Help_200.PDF document in the Windows
Start | Programs menu to verify that the USB driver
was installed successfully.
