NOTE: This configurator is for the older Wiznet Devices that are not supported by their newer tools. It will not configure the currently supported devices. If you have a recent WizNet device you can run their software on the Mac with a few gotchas. Please visit the new Wiznet Serial To Ethernet Configuration page for more info.

The wiznet cards are convienient and reliable ways to get a serial device connected to your network and not need a USB/Serial adaptor. Unfortunately they did not have a Mac version of their configuration utility. Luckily they did document the protocol for configuring the devices and so I created a Mac utility to do so.

Several other pages on this wiki reference and talk about the wiznet boards, for more information please see:
