UART Communication Selection
There are three UART communication options:
USB to UART (connecting USB cable to U7).
For this connection a driver for CP210x should be installed. The driver can be downloaded
from
http://www.silabs.com/products/mcu/Pages/USBtoUARTBridgeVCPDrivers.aspx
RS232 to UART (connecting RS232 cable to J33).
UART input (connecting UART cable to J26).
J6 on DB must be open in order to work in UART mode.
Using J11 and J12 jumpers, the following three options are available (see Table 2).
