Chapter 2 – Getting Started
This chapter describes the GESBC-3130 working environment and familiarizes the user with its
components and functionality. This chapter contains the following sections:
•Assembly and Connections
oDescribes how to assemble and connect components to the GESBC-3130 Single
Board Computer
•Operation
oDescribes how to operate the GESBC-3130 Single Board Computer
Assembly and Connections
In order to use the GESBC-3130 the user must first assemble and connect the peripherals to the
GESBC-3130, as described in the following procedure.
1. Place the GESBC-3130 on a static free surface.
2. Make sure all of the jumpers are in the factory default position. The unit is shipped in a
factory default configuration. If the user is uncertain that the GESBC-3130 has the jumpers
in the factory default configuration, please see the next section regarding board
configuration.
3. Connect 5V regulated power supply to J1 on the board.
4. Connect null modem serial cable between GESBC-3130 debug port and PC/terminal serial
port.
5. Launch a terminal emulator, such as HyperTerminal, or minicom, on the PC configured to
connect to the serial port of the GESBC-3130. Configure the serial port with the following
parameters: 115200 bits per second, 8 data bits, no parity, 1 stop bit, no flow control.
6. Connect the board to a local area network (optional)
Operation
A few seconds after applying power to the GESBC-3130, debug information will be displayed on
the terminal program. The following figures show what this should look like.
