The sat-nms ACU provides a lot of input/output signals. They all are described in the following chapters. Many applications do not require all ports of the ACU to be cabled. For a minimum antenna control functionality however you should connect the following to the ACU:

• A computer via Ethernet, so you can configure the ACU through it's Web-interface
• The power supply (24V, regulated)
• The azimuth position sensor
• The azimuth motor driver circuitry
• The elevation position sensor
• The elevation motor driver circuitry
