Abstract

The sat-nms Antenna Control Unit (Outdoor Module) is an antenna controller / positioner with optional satellite tracking support. It may be operated as a stand alone unit or in conjunction of the sat-nms ACU-IDU, a PC based indoor unit which offers extended tracking capabilities and a full featured visualization interface. The ACU-ODM is designed as a closed, compact module, prepared for mounting on a 35mm DIN rail.

This document describes how to install, setup and operate this antenna controller.
