Setting up your host PC

1. Connect the RS-232 cable (included with the evaluation kit) between the SBC connector P8 and a free RS-232 port on your host PC.
2. Identify the host PC interface and port you will be using for communication with the SBC:
   • For Linux hosts, the serial port in most cases would be called like one of the following (where n is a positive integer): /dev/ttyS0, /dev/ttyS1 ... /dev/ttySn
   • For Windows Hosts, the serial port in most cases would be called like one of the following (where n is a positive integer): COM1, COM2 ... COMn
3. Start a terminal emulation program (such as HyperTerminal on Windows or minicom on Linux).
4. Within the terminal emulation program, in the serial port configuration section select the port identified in previous step.
5. Within the terminal emulation program, in the serial port configuration section, set the following serial port parameters:
   • Baud Rate: 115200
   • Data Bits: 8
   • Stop Bits: 1
   • Parity: none
   • Flow Control: none

Setting up the Compulab SBC

1. Make sure DS3 LED is OFF while DS2 LED is ON. If this is not the case, populate jumper E3.
2. Start the system by enabling power through the main DC power connector.
3. Console messages should appear on your host PC through the terminal emulation program.
