iPort/AI 2 brings I²C directly to any computer with an RS-232 serial port. Just plug an iPort/AI 2 into your computer's legacy or add-on serial port and you will be sending and receiving I²C Bus messages at up to in seconds. Use our free utility software, or create custom apps using our MS.NET Class Library, LabVIEW VI Library, or ASCII Command Interface.

This second-generation iPort/AI:

• Doubles the I²C Bus data throughput.
• Adds our 0.5v to 5v Circuit Sense bus voltage sensing technology.
