Hi, Is it possible to connect a PIC chip to an ethernet socket? If so how, and does anyone know how to send the data using VB?

Yap i think its possible depends on what you want to do
have a look at this baby

What i really want to do is use it like im using serial now but i can see that in the next year or so im going to need something a lot faster than serial and ethernet seems to be what lighting people use now. Im not going to be sending webpages. It will just be a string of about 1024 bytes. When testing with my serial circuits ive found that anything over 22 bytes is just too slow. 22 bytes will work fine for now but i will need ethernet soon. Possibly even for the next project

I have a SPKI developer kit. With it my PIC talks RS232 to the SitePlayer who has a web page. Any browser can see the webpage and get/send information.
SitePlayer also has a Serial Port box that allows sending data over a network from RS232 devices.

I dont want something that can be accessed by a browser. I just want to send raw binary data. If it has the basic TCP/IP stuff then it will work fine but i dont want the HTTP protocol too. Its not for anything to do with webpages. Its for PC <> Lighting link

Very compact and highly integrated, the EM202 Ethernet module features built-in Ethernet magnetics, RJ45 connector, and even four status LEDs! While being a true one-component Ethernet solution, the EM202 has a board footprint just slightly bigger than that of a regular RJ45 connector. Like all the modules in the range its BASIC programmable.

That looks good :)

The EM1202 looks good too. 4 serial ports. The idea of this circuit is to control lights that are quite far away. That would mean 1 ethernet cable (maby even a wireless adapter plugged in) instead of 4 serial cables.

Its a little expensive but another idea was to use a PC to accept the ethernet so the price isnt too bad compared to a PC

Thanx :)

I have test the EM202-EV modules. Is just the EM202 on a board with serial adapter chip and SMPS power supply on a small footprint PCB.

It worked great and fast. I am very pleased with performance though pricey...

Another solution is to use an old net card from PC and do the control with a PIC. Google and you shall receive!

You mean i could make a circuit which connects to a PCI card? :O That could be usefull for some many things :D Ill deffo google that

Yes exactly that! The ISA cards I think are easier to manage because the pcb has larger pads, but PCI could also be used with a little dexterity.
