Procedure
The MAX9259 EV kit is fully assembled and tested.
Follow the steps below to verify board operation:
1) Visit www.maxim-ic.com/evkitsoftware to down-
load the latest version of the EV kit software,
9259Rxx.ZIP. Save the EV kit software to a tempo-
rary folder and uncompress the ZIP file.
2) Install the EV kit software on your computer by run-
ning the 9259Rxx.msi program inside the temporary
folder. The program files are copied and icons are
created in the Windows Start | Programs menu.
3) Verify that all jumpers are in their default positions,
as shown in Table 1.
4) Connect the Rosenberger cable from MAX9259 EV
kit connector J1 to MAX9260 EV kit connector J1.
5) Connect the parallel data source to header H1 (if
using static data without a pixel clock, use an exter-
nal function generator to drive PCLK_IN).
6) Optional Audio Demo: Connect the S/PDIF audio
source (e.g., DVD player digital output) to MAX9259
EV kit phono jack J21. Or, connect an I
2
S audio
source to header H1 and remove jumper JU210.
Connect speakers to MAX9260 EV kit SPKR_L+/
SPKR_L- and SPKR_R+/SPKR_R- oval pads, or plug
headphones into J206 headphone jack.
7) Connect the USB cable from the PC to the MAX9259
EV kit board (direct 500mA connection required; do
not use a hub). A New Hardware Found window
pops up when installing the USB driver for the first
time. If a window is not seen that is similar to the one
described above after 30s, remove the USB cable
from the board and reconnect it. Administrator privi-
leges are required to install the USB device driver
on Windows.
8) Follow the directions of the Found New Hardware
window to install the USB device driver. Manually
specify the location of the device driver to be
C:\Program Files\MAX9259 (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 for additional
information.
9) Verify that MAX9259 EV kit LED120 lights up,
indicating that the microcontroller is powered and
enabled.
10) Verify that MAX9260 EV kit LED120 lights up,
indicating that the microcontroller is powered and
enabled.
11) Verify that MAX9260 EV kit LED2 lights up, indicat-
ing that the link has been successfully established.
If LED2 is off or LED1 is on, double-check that the
PCLK_IN signal is clocking data.
12) Optional Audio Demo: Press and release switch
SW122 on both of the MAX9259 and MAX9260 EV
kits to enable this S/PDIF-to-I
2
S and I

S-to-audio
DAC demonstration circuitry. If I
2
S or S/PDIF audio
was provided to the MAX9259 EV kit, audio should
now be heard from the speakers or headphones
previously connected to the MAX9260 EV kit.
13) Start the MAX9259 EV kit software by opening its
icon in the Start | Programs menu. The EV kit soft-
ware configuration window appears, as shown in
Figure 7.
14) Press the Connect button and the configuration
window disappears.
15) The EV kit software main window appears, as shown
in Figure 1.
16) Press the Read All button to read all registers on the
MAX9259 and MAX9260.
