Cables and Cabling Configurations
UART Interface Cabling
Debugging or bringing up the card required the use of a USB-to-UART cable that is included in the package contents. Upon inspection, there is a USB
connector with USB 2.0 full speed compatibility and 3 single pole 0.1m pitch header that connects to a serial port on the Controller Card. The following
figure shows an example of a USB-to-UART Cable, and the table provides the cable signal description.
