This episode of BRStv goes over the Apex base unit for the Apex Aquarium controller and all the connections. The main ports to familiarize yourself with are the ethernet port, temperature port, I/O Breakout box port (you will need to purchase the I/O Breakout box separately), pH/ORP ports and finally the variable voltage or speed connector most commonly used for DC controllable pumps like the Tunze Stream pumps or to dim LED lights like the Kessil.
How do you use your base unit? What is your set up?
