Return all jumpers to the
default factory settings. See
Table 3-2 and Figure 3-1.
Install the FlexGUI
software. See Section 4.1.
Connect a +5 V power
supply to the +5V_EXT
and GND binding posts .
Connect a USB cable
from a Windows-
compatible PC .
Start the FlexGUI software. Using
the “Quick-Setup” drop -down list on
the “Board Config” tab , restore the
factory register configuration called
“2. Analog in – I2S – 48k FS –
12.288M MCLK – Master mode” .
7
Connect differential or single -
ended signals to any of the
eight 1/8" input jacks. Full-
scale input corresponds to a
differential voltage of 1.48 Vpp.
When using a single -ended
source, shunt IN
–
to ground by
placing a jumper at the “IN
–
“
position (Pins 1 and 2) on the
Sleeve/IN- jumper pin block .

Connect a serial audio
analyzer to the Serial
Header . The header
signals are described
in Table 2-1.
9
Optional : Connect
an audio analyzer to
the S/PDIF RCA or
optical output . The
stereo pair at these
outputs corresponds
to analog input pair
1.AIN1 and 1.AIN2.
Return all jumpers to default
factory settings. See
Table 3-2 and Fig. 3-1.
Install the FlexGUI software.
See Section 4.1.
