MAX14819 Evaluation Kit
Evaluates: MAX14819
General Description
The MAX14819 evaluation kit (EV kit) consists of the
evaluation board and software. The EV kit is a fully assembled
and tested circuit board that evaluates the MAX14819
IO-Link
®
dual-channel master transceiver.
The EV kit includes Windows
®
7-compatible software that
provides a graphical user interface (GUI) for exercising
the features of the device. The EV kit is connected to a
PC through a USB A-to- micro B cable.

Features
*L+A and L+B are each configured for a 1A (typ) current
limit, so a higher load-capable power supply may be
required for testing.

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:
1) Visit
www.maximintegrated.com/evkitsoftware
to
download the latest version of the EV kit software,
MAX14819EVKITSetupVx.xx.ZIP. Save the EV kit software
to a temporary folder and uncompress the ZIP file.

2) Install the EV kit software and USB driver on your
computer by running the MAX14819EVKITSetupVx.
xx.EXE program inside the temporary folder. The
program files are copied to your PC and icons are

menu. During software installation, some
versions of Windows may show a warning message
indicating that this software is from an unknown
publisher. 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.
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.
5) Connect the multimeter to the V5 testpoint (TP22)
6) Connect the USB cable from the PC to the EV kit
board. A Windows message appears when connecting
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.
7) Start the EV kit software by opening its icon in the
Windows
Start | Programs | Maxim Integrated
menu.
The EV kit software main window appears, as shown
in
Figure 1.
8) Verify that
Status: MAX14819EVKIT A Connected
is
displayed on the status bar at the bottom of the main
window (Figure
1).
9) Turn on the 24V supply. Ensure that the V5 voltage
(TP22) is 5V.
10) Click on the
Read All button
to read all of the registers
in the device.
11) Select a register in the register table to access the bits
in that register by clicking on the register name.
12) Using the Register Bit Description table that pops up,
set the individual bits by selecting the required setting
from the drop-down menu for each bit.
13) Press the
Write Changes
button on the GUI to
write the registers that have been changed to the
MAX14819.
setting. When all of the bits are set as desired, click on
the Write Changes button to write the changed bit setting
s to the MAX14819 over the SPI interface.
Note that full IO-Link communication is not available using
the EV kit GUI. Please use the MAXREFDES145 for full
IO-Link communication with the MAX14819.
Interrupt Response (IRQ)
The MAX14819 features an integrated active-low interrupt
indicator pin to actively notify the controller when an interrupt
or error condition occurs. Enable interrupts in the by
setting the bits in the InterruptEn register.
When an interrupt is triggered, the IRQ bit in the SPI
communication is set and the IRQ in the SPI Response
box of the GUI turns red. On the EV kit PCB, the IRQ LED
(DS6) also turns on.
Detailed Description of Hardware
The MAX14819 EV kit includes the MAX14819 dual-
channel IO-Link master transceiver and the external
components for evaluating the device. All logic-level I/
Os and IO-Link capable I/Os are available on yellow test
points.
Logic-Level Power Supply
The MAX14819 features an internal 5V linear regulator
which can drive loads up to 20mA. When REGEN is
unconnected, this 5V output is available on the V5 test
point (TP22). Leave J13 open and close the J5 jumper
to use this internal 5V regulator to power the logic level
supply (VL).
To use a different logic-level voltage supply, open the J5
jumper and apply the external supply to the VL testpoint
(TP23).
Selecting the Device Address
The MAX14819 includes two address pins for SPI addressing,
allowing up to four devices on a single bus. Set the SPI
address for the MAX14819 on the MAX14819EVKIT by
setting the A1 and A0 jumpers (J11 and J12, respectively).
Set the device SPI address in the GUI to the same value
by selecting the corresponding address in the drop-down
menu in the SPI Address box.
Detailed Description of Software
Configuring the Registers
Click on a register name in the register table to access
the individual bits in that register. When the register name
is selected in the register table, a corresponding Register
Bit Description table appears, allowing access to set
individual bits. Click on the drop-down menu next to each
bit in the Register Bit Description table to select the bit
Using SPI Interface with an External Master
Controller
The MAX14819 EV kit includes an isolated USB-to-SPI
interface circuit for communication with the PC/GUI.
To use an external SPI master controller with the
MAX14819, open all of the channels on SW1, and con-
nect an the external SPI master to the J20 header. Note
that the J20 header is not isolated from the MAX14819.
