The kit PC to PC communication deals with data transfer from one computer to another. It uses programming and the serial ports of the PCs. The ports are programmed. We use USB to UART module logic to convert USB logic to TTL logic and then a wireless transmitter circuit to transmit data (X-bee transmitter. The transmitter circuit has a RF CHANNEL which is matched. At the receiver we have a wireless receiver circuit which receives data using X-bee receiver and USB to UART module to convert TTL logic to USB data for the serial port at the receiving end computer.
The desired baud rate can be set using the program. For transmitting data the program is executed once and whatever is present at the serial port is sent to the other computer via the wireless medium. At the receiver the program is executed to receive data on the serial port.
TThe main objective of this kit the user has to just establish the connection between two systems then whatever he will write will be sent to another computer. This is full duplex bi-directional operation.
