There are two types of Pulse units and which one to choose depends on which port your meter has. What is a bit tricky is that both of these ports are referred to as HAN-port but the form differs. This is how they look like:
Pulse P1 is the black unit and fits with a P1 port also known as RJ11 or RJ12.
