Infrared data transfer and communication system using Visual Basic / Mohamad Arif Abdul Majid

The Infrared Data Transfer and communication System consist of an infrared Transceiver hardware and software. The system enables two personal computers connected over a wireless medium via infrared link. The Infrared Data Transfer and Communication System allow users to transmit text, data or file via infrared to a remote PC using the RS232 serial port. The system has an achievable link distance of 1 meter with speeds of up to 115200 bits per second (bps). The hardware design involves implementation of the HSDL-7001 Encode/decode IC and HSDL-1001 infrared Transceiver. The hardware also consists of an interface circuit between the serial port and the infrared hardware using the ICL232 chip. Visual basic language is used to control and communicate with the hardware developed. The software is capable of sending and receiving data from the infrared hardware. The software is also able to control and set the bit rate of the communication link.
