Topic: Why does my Ethernet Shield not work? (Read 1 time) previous topic - next topic

Dear all,

I'm an Arduino newbie, so forgive me if I'm maybe missing the obvious ...

Together with my Arduino Mega 2560 I got the following Ethernet Shield from watterott.de: .

Does anyone know which specific type of Ethernet Shield this is? It looks quite different from the V5 on arduino.cc.

I can access the Micro SD card properly using the sdfatlib20101010. However, I can't get the Ethernet to work.

I tried with a regular cable. I also crimped a cross cable. I connected both to my Notebook and to an Wifi Access Point. Under no circumstances do I get the physical link established (I mean, the LED's on the NIC of the Notebook don't light up, nor does the Access Point LAN LED light up).

Any clue what I'm doing wrong?

Kind regards,
Sebastian

You will probably have to do some pin changes on the mega as the mega has different pin locations than the other arduino boards. There have been previous post on the subject that a search might find.

Well, I don't really understand this pin 53 business. On top of this, see that instead of the standard pins 10, 11, 12, 13 on my shield pins 3, 5, 6, 9, 10 and 11 are marked? I really seem to first need the schematics of this shield, don't you think? Or maybe I should return this shield and rather ask for exactly the V5 as documented at http://arduino.cc/en/Main/ArduinoEthernetShield?

Perhaps you should have been a little more knowledgable about what you were buying before making your purchase. Keep the mega as a learning experience and purchase a regular arduino if you need a direct pin plug up.

I have a V5 ethernet shield attached to a mega 2560 and it works really well.  The 'official' arduino was modified especially to work with the mega boards, and at least in my case, does.  The fact that you don't have a light on the router when you plug it in and power it up probably means the board itself is actually bad.  The ethernet board will interact to a small degree with a router with only power supplied and no program at all on the arduino.  Additionally, there have been reports of seemingly official arduino ethernet boards that were very different from the V5 cards pictured on this site; they even came in the cardboard box.

I recommend you contact the supplier, they'll probably work with you on this.
