TROUBLESHOOTING
SOFTWARE
To troubleshoot the software, take the following steps:
1. Always install the software before connecting the hardware to
the PC.
2. Always allow the install to fully complete (the software is a
two-part installation, the ADC evaluation software and the
SDP-H1 drivers). A restart is recommended after
installation is finished.
3. When the user first plugs in the SDP-H1 board via the USB
cable provided, allow the new Found Hardware Wizard to
run, which may take a little time. However, allow this to
happen before starting the software.
4. If the board does not appear to be functioning, ensure that
the ADC evaluation board is connected to the SDP-H1 board
and that the board is being recognized in the Device Manager,
as shown in Figure 14.
5. If connected to a slower USB port where the SDP-H1 cannot
read as quickly as it needs to, a timeout error may result. In
this case, it is advised not to read continuously, or
alternatively, to lower the number of samples taken.
HARDWARE
To troubleshoot the hardware, take the following steps:
1. If the software does not read any data back, do the following:
a. Check that the power is applied within the power
ranges described in the Power Supplies section.
b. Using a voltmeter, measure the voltage present at each
of the test points: +VS, −VS, 1P8V_VDD, VDD_1P8V,
+3P3V, +5V, and REF1and common-mode voltages
(REF/2) at IN+ and IN− to ensure that they are
correct. The SDP-H1 board LED1 must be lit.
c. Launch the software and read the data. If nothing
happens, exit the software.
d. Power down the board and relaunch the software.
e. If no data is read back, confirm that the ADC evaluation
board is connected to the SDP-H1 board and that the
board is being recognized in the Device Manager, as
shown in Figure 14.
2. When the user is working with the software in standalone/
offline mode (no hardware connected) and later chooses to
connect hardware, close and relaunch the software.
