iPort/LAN^TM

Tired of traveling to remote sites to monitor systems or fix problems? Then...

Get off the plane, get on the bus, with iPort/LAN^TM

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.

(Limited Availability - Coming Soon iPort/LAN 2)

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.

Which I²C Adapter is right for me.

The iPort/LAN is our most extensible I²C Bus host adapter. Capable of accessing I²C Bus devices directly, over a Local Area Network, or over the Internet, the iPort/LAN will operate with any Windows PC. Typical applications include monitoring remote sites, update delivery, remote EEPROM programming, device control and sensor networking.

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 port.
