General Description
Features
The MAX31910/11 evaluation kit (EV kit) provides
the hardware and software (graphical user interface)
necessary to evaluate the MAX31910 and MAX31911
industrial octal digital input translators/serializers. The EV
kit includes a MAX31910AUI+ or MAX31911AUI+ installed
as well as a digital isolator and USB-to-SPI interface.

OS-Compatible Software
The USB to SPI Dongle is a separate PCB that can be
used to interact with the EV kit software. This dongle is
optional and is not necessary for the proper operation of
the MAX31910/11 if the user supplies the SPI interface.
S RoHS Compliant

Quick Start
visit www.maximintegrated.com/evkitsoftware to
download the latest version of the EV kit software,
MAX31910_11EVKitSoftwareInstall.ZIP. Save the
EV kit software to a temporary folder.
Note: In the following sections, software-related items
are identified by bolding. Text in bold refers to items
directly from the install or EV kit software. Text in bold
and underlined refers to items from the Windows operat-
ing system.

lisher could not be verified. Are you sure you
want to run this software? may appear. If so, click
Yes.

Procedure
The MAX31910/11 EV kit is fully assembled and tested.
Follow the steps below to verify board operation.
12) Connect field inputs to J5 or install jumpers on FIN1-
FIN8 and click Single Read.
Detailed Description of Software
1) Connect the USB to SPI Dongle (J52) to the EV kit
connector J3.
2) Install jumpers on RIREF (J2) and SIN-GND (J6).
3) Set the EV kit hardware on a non-conductive sur-
face that will ensure that nothing on the PCB will get
shorted to the workspace.
4) Use the wires to connect J1 (VCC and GND) to a
power supply and tighten the screws on the wire.
5) Prior to starting the GUI, connect the EV kit hard-
ware to a PC using the supplied mini-USB cable, or
equivalent.ꢀTheꢀPOWERꢀLEDꢀ(D50)ꢀshouldꢀbeꢀgreenꢀ
andꢀtheꢀCOMꢀLEDꢀ(D51)ꢀshouldꢀbeꢀredꢀandꢀslowlyꢀ
flash orange.
6) Windows should automatically begin installing the
necessary device driver. The USB interface of the
EV kit hardware is configured as a HID device and
therefore does not require a unique/custom device
driver.ꢀ Onceꢀ theꢀ driverꢀ installationꢀ isꢀ complete,ꢀ aꢀ
Windows message will appear near the System Icon
menu indicating that the hardware is ready to use.
Do not attempt to run the GUI prior to this message.
If you do, then you will have to close the application
and restart it once the driver installation is complete.
Onꢀ someꢀ versionsꢀ ofꢀ Windows,ꢀ Administratorꢀ privi-
leges may be required to install the USB device.

the button text will change to Stop for the user to stop
the reads.
Hardware Configuration
In this section the user must provide hardware configura-
tion information about the EV kit. Select the 8 Bits radio
button in the Number of BitsꢀsectionꢀifꢀMODESELꢀdoesꢀ
not have a jumper on J6. Select the 16 Bits radio but-
tonꢀifꢀMODESELꢀisꢀconnectedꢀtoꢀGNDꢀonꢀJ6.ꢀIfꢀthereꢀareꢀ
more MAX31910/11 daisy chained to the EV kit, select
the number of devices with the Number of MAX31910/11
combo box.
Data
The Data table displays the 8 or 16 bits read from each
device connected to the EV kit. The first row of data is
the first 8 or 16 bits read from the device connected to
the microcontroller. The second row is the data read
from the device connected to the SIN of the first device
(see Figure 2). The MAX31910/11 column displays the
device name. The device name can be changed by
clicking on the name twice. The HEX column displays the
data in hexadecimal format for each device. The Input
Channels, CRC, UV Alarm, and OT Alarm columns
display the data in binary format.
Reads
To read the input channels of the devices, select Single
Read. This will calculate the number of bits to read
based on the Hardware Configuration settings and then
display the read data in the table. Continuous Reads
will read the input channels every 300ms and display the

User-Supplied SPI interface
The USB to SPI Dongle is an optional PCB that is only
needed to interact with the MAX31910/11 software. The
user has the option to supply an external SPI interface
to communicate with the MAX31910/11. To connect a
user-supplied SPI interface, remove the dongle from J3
J2
J6*
and connect an external SPI interface to the pins on J3.
Removing the dongle also removes the isolator, so the
user may also want to provide an external digital isolator.
FIN1–FIN8 Field Inputs: Connects field input FINX to VIN
*These inputs have internal pullups.

is suspected, refer to the below table to help troubleshoot the issue.
SYMPTOM
CHECK
SOLUTION
If yes, then the electronic fuse, U50, is in a fault state. Inspect for
electrical shorts on the PCB and make sure that the PCB is not
sitting on a conductive surface.
IsꢀtheꢀLEDꢀlabeledꢀD50ꢀred?
If not, then exit the GUI and try running it again. If D51 still does
not turn green, then exit the GUI and try connecting the USB cable
to a different USB port on the PC and wait for a Windows message
that states the hardware is ready to use. Run the GUI again.
GUI says hardware
not found.
DoesꢀtheꢀLEDꢀlabeledꢀD51ꢀturnꢀ
greenꢀwhenꢀtheꢀGUIꢀisꢀrunning?
If not, then the PCB may not be getting power from USB. Try a
different USB cable or a different USB port
