sat-nms ACU-RMU NEC Version User Manual

Version 2.3.0 -- 2023-07-04 -- (C) 2003-2023 SatService GmbH

Abstract

The sat-nms ACU-RMU is a full featured antenna positioner and antenna tracking system. It is completely integrated to a 6RU 19inch case. The interfaces are compatible to formerly installed NEC antenna drive systems. By this an easy plug-and-play replacement could be performed.

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