3.1 12BSwitches and Jumpers
The evaluation system comprises switches and jumpers used to select the desired configuration states of the
board. Default configurations are indicated as 'default.'
3.1.1 17BUART 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).
