JUMPER
are created in the Windows Start_ |_ Programs
menu.
Verify that shunts are correctly installed on the
jumpers listed in Table 1 for proper operation of the
EV kit.
Connect the multimeters across the MAX5386M’s
(U1) WA and LA PCB pads and WB and LB PCB
pads.
Connect the MINIQUSB+ interface board to the EV
kit J2 and J3 connectors.
Connect the included USB cable from the PC
to the MINIQUSB+ interface board. A Building_
Driver_ Database window pops up in addition to
a New_Hardware_Found message when installing
the USB driver for the first time. If a window similar
to the one described above does not appear after
30s, remove the USB cable from the board and
reconnect it. Administrator privileges are required
to install the USB device driver on Windows 2000/

Follow the directions of the Add_ New_ Hardware_
Wizard to install the USB device driver. Choose the
Search_for_the_best_driver_for_your_device option.
Specify the location of the device driver to be
C:\Program_ Files\MAX5386M (default installation
directory) using the Browse button. During device
driver installation, Windows may show a warning
message indicating that the device driver Maxim
uses does not contain a digital signature. This is
not an error condition and it is safe to proceed
with installation. Refer to the USB_Driver_Help.PDF
document included with the software if you have
problems during this step.
Start the EV kit software by opening its icon in the
Start_|_Programs menu.
Observe as the program automatically detects the
USB connection and starts the main program.
Using the Device_ Connected combo box, select
MAX5386 from the list and then press the Default
button. The EV kit software main window appears,
as shown in Figure 1.
