Procedure
The EV kit is fully assembled and tested. Follow the steps
below to verify board operation:
1)
Visit
www.maximintegrated.com/evkitsoftware
to
download the latest version of the EV kit software,
MAX11300EVKitSetupV1.1.zip. Save the EV kit soft-
ware to a temporary folder and uncompress the ZIP
file.
Install the EV kit software and USB driver on your com-
puter by running the MAX11300EVKitSetupV1.0.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 soft-
ware 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.
Note:
The software
requires .NET Framework v4. If this framework is not
detected during installation, the installer launches
dotNetFx40_Full_setup.exe to install it. Internet ac-
cess may be required to install the .NET Framework
v4 if it is not already installed.
Verify that all jumpers are in their default positions, as
shown in
Table 1, Table 2, Table 3,
and
Table 4.
Configure the power supply for ±12.5V DC output
(typical load current is 50mA) (be sure to keep AVD-
DIO-AVSSIO within rated supply range).

5)
Connect the +12.5V DC power supply between
AVDDIO (+) and GND (-). Connect the -12.5V DC
power supply between AVSSIO (-) and GND (+).
Connect the DVM- to GND (-)
Enable the power-supply output.
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,
proceed to the next step. Otherwise, open the
USB_Driver_Help_200.PDF document in the Win-
dows
Start | Programs
menu to verify that the USB
driver was installed successfully.
Use the DVM+ to verify the test point voltages shown
in
Table 2.
