15. Set  up  the terminal program to run on the PC using the following steps. Before 

loading the executable firmware file  on the FPGA, the terminal program on the 
PC should be running. The example firmware running on the FPGA 
communicates with the PC via a USB port set up to emulate a serial port (UART). 
To establish this communication link, the PC must be configured with the 
appropriate Windows drivers. A suitable terminal program such as Tera Term or 
HyperTerminal should be invoked. 
 
The micro USB (J3) on the LX9 is the communication port. The LX9 utilizes the 
Silicon Labs CP2102 USB-UART  bridge IC, so you need to install  Silicon Labs’ 
virtual COM port (VCP) driver for their CP210x device family.  These may be 
obtained from the Silicon Labs website (www.silabs.com). 
 
Once installed, Windows will assign a previously unused COM port. Use the 
Windows 

Control Panel | System | Device Manager

 to determine the COM port 

number. (It will be named 

Silicon Labs CP210x USB to UART Bridge

.) Make a 

note of which COM port this is. That information is needed in the next step. 
 
Next, a terminal emulation program needs to be installed and launched. For 
Windows XP® and earlier systems, the HyperTerminal  program is the usual 
choice. However, since HyperTerminal  was eliminated from Windows 7, it may 
be necessary to locate an alternative. Several are available; one good choice is 
called Tera Term  (http://ttssh2.sourceforge.jp/).  Whatever  terminal  program you 
choose, the communication should be set up by opening the COM port number 
previously described above and the port configured as:  
 
bits per second: 

115,200
