Sending FS20 commands using a Arduino and a TX868-75

Hello fellow Arduino users, I have a Arduino Uno, and I want to send FS20 commands.

I've got a TX868-75 (http://www.elv.de/hf-sendemodul-tx868-75-868-mhz.html)

Two questions on this matter;
1-The TX868-75 has 3 connectors, plus, ground and signal, what is the best way to connect the signal pin to the Arduino? The TX868-75 expects 3volts on the singal pin, but the arduino sends 5 volts.
2-Does anyone have a software example on how to send commands to the TX868-75 module?

I found some german forum posts on question one, but I don't really understand that.

Thanks in advance!

  1. I've got this from a german forum, apparently a 150 ohm resister should do the job.

  2. Second question;

Kudo's for Jean-Claude Wippler!
