I’m afraid I can’t help you with that,sorry. You might want to start with a good electronics text book, to get a sense of how it’s all done. I have some recommendations for books here: http://www.tigoe.net/blog/topics/books/

I haven’t used the Lantronix devices in a couple years, but at that time they could do DHCP. You just set the IP address to 0.0.0.0 and let the network self-assign. However, you have no way of knowing the device’s address remotely without it contacting you. I have an example somewhere on this site that sniffs out Lantronix devices via UDP though.

Hey tigoe, very nice site you have here! I’m starting a project using a Lantronix Xport to web enable my microcontroller (not arduino). Is there a way that you know of that using DHCP, my microcontroller can print the IP address to an LCD or something by obtaining it from the Xport? I’m trying to find a way where I can just plug into any network and see what IP it gets assigned without having to run DeviceInstaller or any other sniffer to find the IP from another network device on the segment. It’s my first project with network devices so any advice would be appreciated. Thanks.

Hi Tom,
I do not understand much of what is on your site. I would like to build a bank of 48 led and 48 uv lights and pulse them at frequencies up to 10,000 per second. I found a frequency generator at resonantlight.com called the Pro Gen ll but the output is only 100mA and the engineer says I need a high current transistor switching circuit to produce the desired power. Any ideas about how I can build one or buy one?
Thanks,
John

I like very much your project Arduino-based RFID reader, I have a question can I use and modify your code on a school project? I will of course show the source on presentation.
