When I use the TPC 400 do I also need to use the Command Base Cable that connects to the TPC unit? That is the connection made with the cable that looks like a computer cable and has red and green wire that connects to the TPC 400. It connects to the TPC 400 and Command Base. Do I need this connection to make everything work?

If you can't tell I'm new to TMCC and I will be using a 180 Power House Brick along with the TPC 400, Command Base and Cab 1.
