||RS-232 to I2C Host Adapter with ASCII Interface|
iPort/AI brings I2C directly to any computer with an RS-232 serial port. Just plug iPort/AI into your computer's serial port, and you will be sending and receiving I2C messages in seconds.
I2C Bus is the Inter-Integrated Circuit serial bus developed by Philips Semiconductor for inter-IC communications. Now, this highly efficient and cost effective communications link is being adopted by leading technology companies worldwide for chip, board, and system level communications.
An I2C Bus network can support up to 127 Master or Slave devices with a 2-wire serial interface. I2C devices can be as simple as RAM, EEPROM, or I/O devices, or have the full-blown processing power of an embedded microcontroller or microprocessor.
Master, Slave, Transmit, Receive. iPort/AI supports I2C message modes including Multi-Master, Arbitration Detection, and messages from 1 to 32K bytes in length.
Start sending I2C messages in minutes using our Message Manager
or Message Center applications included with each adapter. You
can also use your computer's terminal emulation software (like
Windows' Hyperterminal Program), or create your own custom I2C
applications using any programming tool that can access your computer's
ASCII Text Interface Commands
