First question:

How can I connect an RDM630 RFID to the Arduino Mega 2560?
I have try many versions but no one works.


Second question:

Which simple code should work if the connection is ok?
I want to read an Chip-Code and on the Serial Monitor I will get the name of the owner of the chip.

Sorry, but I have the Arduino since few days. I hope that someone can help me.

First, you post a link to the hardware you want to connect/read from. Then, we can help you.

This are the components which I will connect:

On the page for the RFID reader, there is a link to a wiki that shows exactly how to connect the RFID reader to the Arduino, complete with big pictures.

The programming on that page is typical seeedstudio rubbish.

How you can see I have an other Arduino Board as shown in the wiki.

"Tx from RFID board goes to Digital PIN 2 on Arduino Board."

Which Pin is it on my board? I connect PIN2 nearly PIN0(RX0) and PIN1(TX0). Is it right?

On the Serial Monitor there is only:

"SeriSerial Ready
RFID Ready"

When I test it whith an chip, there is nothing else on the Monitor.

If I connect additionally the Reset-PIN with GND and change the wire from connection PIN2 on my board to PIN1(TX0) the Serial-Monitor shows the Chip-Number when I test it with a chip.

But the programm does not what it should do.

What is wrong?

No, it isn't. The pins on the Mega (and all other boards) are clearly labeled). If RX0 and TX0 are pins 0 and 1, it really isn't too difficult to figure out which is pin 2, is it?
