4.3 Connecting the USB Cable to the SDM-USB-DIG
Figure 7 shows the typical response when connecting the SDM-USB-DIG platform to a USB port of a PC
for the first time. The PC usually responds with a popup dialog window that states Found New Hardware,
USB Device. The popup window then changes to Found New Hardware, Virtual COM Port (CDC). This
popup indicates that the device is ready for use. The CDC driver is used for communication between the
SDM-USB-DIG and PC.

4.4 AMC7832EVM Power Configurations
This section describes the various power configurations that can be used by the EVM.
The AMC7832EVM provides terminal blocks for external supplies as well as (optional) onboard power
conditioning to convert a 24-V supply into a +12-V, -12-V, and 5-V supply. Jumpers JP3 and JP6 can be
configured to use external supplies through the J2 and J11 terminal blocks or the jumpers can be
configured for the onboard regulated supplies. Additionally, the AV
CC
and AV
EE
inputs are, by default,
connected to external terminal blocks, but can be configured to use the onboard regulated supplies by
populating the shunt resistors as shown in
Table 5 .
