How do I connect the Ultrasonic SRF06 sensor to Arduio Uno?

Hello, I do not understand how to connect the 5-pin sensor Arduino and above what they are the connections shown in the figure.

Can you help me?

Do you have the SRF06 with current-loop output?

If you have the more common 4-pin version:
