IFethernet

Ethernet Interface Module

RJ45 - Intel inside!

Most of our single board computers have one or more IF connectors. For the wiring of the IF connector see table below.

The IFethernet continues the series of IF-Modules. IFethernet consists of a RJ45 connector, the XPort from LANTRONIX, which contains the complete circuitry to convert serial to ethernet. Inside XPort is a 80186 processor with 256KB RAM and 512KB FLASH.

On the board, a DC-DC converter generates the required 3.3V from 5V with minimal loss of power. The conversion of logic levels from 3.3V to 5V and vice versa is also done on-board.

There are two 10-pin connectors. The first connector has the same wiring as the IF232, except for a few missing handshake lines. This connector is for connection with the SBCs from Paul und Scherer, using a flat ribbon cable. The second connector has the same wiring as an SBC and allows the connection of an IF-Module, e.g. an IF232. Thus, the conversion of ethernet to RS232 is also possible. There is an extra power connector for this mode.

For the PC side, a Windows driver is supplied. The current version of the driver is available from Link: LANTRONIX for free download. The driver installs a virtual COM port on the PC, i.e. programs access the driver as a "normal" COM port. The driver then "redirects" data to the network. A terminal programm, for example, can so connect to a single board computer via ethernet.

LANTRONIX also offers various utilities for download. IFethernet can for example be used as a Web server...
