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 is not seen after 30s,
remove the USB cable from the board and recon-
nect it. Administrator privileges are required to
install the USB device driver on Windows 2000,
Windows XP, and Windows Vista.
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\MAX5388 (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
MAX5388 from the list and then press the Default
button. The EV kit software main window appears,
as shown in Figure 1.
The EV kit is now ready for additional testing.
