RS-232 to I2C Host Adapter with ASCII
Fast Mode Interface |
|
iPort/AFMTM
iPort/AFM brings I2C directly to any
computer with an RS-232 serial port. Just plug an iPort/AFM
into your computer's serial port, load our free software, and
you will be sending and receiving I2C messages at
up to 400Kbit/s in seconds.

The iPort/AFM is our fastest and most powerful
I2C Bus host adapter. Its RS-232 serial port interface and simple
ASCII commands allows the iPort/AFM to operate with any operating
system, and its compatible with most embedded systems. Applications
include product development and testing, EEPROM loading, device
control and sensor networking.
Over the past few years, the I2C Bus has expanded from simple
control to data intensive applications. As new uses arise, bus
bandwidth and message overhead have become key issues in product
design and testing. The iPort/AFM, our third generation adapter
for the I2C Bus, addresses these issues by supporting several
bus speeds, including fast mode (400kbit/s), and three RS-232
transfer rates up to 115.2K baud. Implemented using a high-performance
bus co-processor with optimized instruction set, the adapter also
includes large message buffers (256 bytes) to reduce host computer
and bus overhead. In addition to operating as a bus master or
slave in a multi-master system, a built-in bi-directional /INT
signal line allows the device to receive or generate slave only
device notifications.
The iPort/AFM will work with any application written for our
iPort/AI, only 4 to 40X faster. When operating with new applications
written specifically for the iPort/AFM, speed increases up to
100X faster are possible.
Master and Slave, Transmit and Receive, iPort/AFM supports
I2C message modes including Multi-Master, Arbitration Loss Detection,
withÝ 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.
