sat-nms ACU2-ODU DC Version User Manual

Version 3.3.1 – 2024-04-23 – (C) 2020-2024 SatService GmbH

Abstract

The sat-nms ACU-ODU is a full featured antenna positioner and as an option antenna tracking system. The electronics of the sat-nms ACU-ODU is build into an outdoor cabinet. The protection class of the cabinet is IP66 if no optional air ventilation is installed. So it is no problem to install it outside without any additional roof.

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