|Ethernet to I2C Bus Host Adapter
with ASCII Fast Mode Interface
Tired of traveling to remote sites to monitor systems or fix problems? Then...
Get off the plane, get on the bus, with iPort/LANTM
iPort/LAN brings Local (LAN) or Remote (INTERNET) I2C directly to your desk. Just load our free software, plug the iPort/LAN into your network, and you will be communicating with I2C Bus devices in your office, lab, factory, or remote sites in seconds.
With the iPort/LAN you can commuicate with I2C Bus systems at direct, local, or remote sites, monitor sensors, control devices, even reprogram EEPROMs. All from your desk. If you think that sounds fantastic, we agree.
Three ways to connect (direct, local, and remote)
Over the past few years, the I2C Bus has expanded from simple control to data intensive applications. As new uses arise, remote access and bus bandwidth have become key issues in product design and testing. The iPort/LAN, our fifth generation adapter for the I2C Bus, addresses these issues by supporting several I2C bus speeds, including fast mode (400kbit/s), and local or remote network access. 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.
Thanks to it's Virtual Communications Port (VCP) driver, the iPort/LAN will work with ComPort based applications written for all our ASCII-text interface based USB and RS-232 to I2C host adapters.
Master and Slave, Transmit and Receive, iPort/LAN supports I2C message modes including Multi-Master, Arbitration Loss Detection, with 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 (virtual) serial
