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 serial port.

iPort/AI ASCII Text Interface Commands
Command	Description
//[CR]	Status Display Display iPort/AI status information. Note: [CR] = Carriage Return Code or Enter Key.
/E[0\|1][CR]	Echo/Prompt Control [0 = Off, 1 = On] Enable/Disable data entry echo and prompts.
/F[0\|1][CR]	Flow Control [0 = XON/XOFF, 1 = RTS/CTS] Select serial communication handshaking protocol.
/C[CR]	Close I²C Connection Disconnect from the I²C Bus.
/Dxx[CR]	Set Destination I²C Slave Address Set the destination I²C Slave Address for subsequent Master Transmit or Receive operations.
/G[0\|1][CR]	I²C General Call Control [0 = Disabled, 1 = Enabled] Enables/Disables iPort/AI response to I²C Bus General Call (00) messages.
/H[0\|1][CR]	Hex Only Display Control [0 = Disabled, 1 = Enabled] Controls display format of received message data.
/Ixx[CR]	Set iPort/AI’s Own I²C Slave Address Sets iPort/AI's own I²C Slave Address. iPort/AI will respond to I²C Bus messages sent to this address.
/M[CR]	Command Menu Display Display iPort/AI's Command Menu
/O[CR]	Open I²C Connection Activates iPort/AI as an I²C device attached to the bus.
