RFID + Arduino issues

Hey Guys,

I have been working for a long time on trying to hook up a long range RFID reader to my arduino mega. But I seem to be failing miserably.

this is my reader

and of course I’m running an arduino mega.

I just can’t seem to get it to work at all. Any help would be appreciated!

Thanks

It looks like that reader has a USB interface also. Is it possible to read tags with USB as a test of the reader? Just to cover all the bases, do you have a known good tag compatible with this reader?

I would also suggest connecting the TTL output to an RS-232 shifter so you can open a terminal program and see the data as it’s read. This one works: http://www.sparkfun.com/products/449

After confirming that the data is appearing on the TTL port, move it over to the Arduino, then start troubleshooting your connections and coding on the Arduino. Post more about your connections and code and the more people will comment.
