iPort/AFM 2 brings I²C directly to any computer with an RS-232 serial port. Just plug an iPort/AFM 2 into your computer's legacy or add-on serial port, load our free software, and you will be sending and receiving I²C Bus messages at up to 400Kbit/s in seconds. This second-generation iPort/AFM doubles the I²C Bus data throughput, and adds our 0.5v to 5v Circuit Sense bus voltage sensing technology.
