1 Introduction
The sat-nms Antenna Control Unit is an antenna controller / positioner with optional satellite
tracking support. It may be operated as a standalone 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 sat-nms ACU is available as:
sat-nms ACU-ODM: only the core-module integrated in a compact case prepared for
mounting on a 35mm DIN rail
sat-nms ACU-ODU: complete antenna controller system for AC- or DC-Motors integrated in
an outdoor cabinet that could be mounted directly to the antenna. By mounting a sat-nms
LBRX beacon receiver into this cabinet, you have a complete antenna tracking system in a
compact cabinet directly at your antenna.
sat-nms ACU-RMU: complete antenna controller system for AC-Motors integrated in a 6RU
19inch rack mount case for indoor use
(C) 2022, SatService GmbH www.satnms.com ACU-ODU-DC-UM-2209 Page 4/67

sat-nms ACU19: complete antenna controller system for DC-Motors integrated in a 1RU
19inch rack mount case for indoor use
For detailed description please refer to the sat-nms documentation CD or www.satnms.com/doc
Main benefits of the sat-nms ACU are:
The ACU outdoor unit is able to act as a standalone antenna control and tracking system
without an indoor unit required.
The ACU provides an Ethernet interface using the TCP/IP and HTTP Internet protocols. It
can be controlled using any PC providing an Ethernet interface and a web browser like the
Microsoft Internet Explorer. The ACU runs a web server which acts as a user interface to the
antenna controller.
The ACU is prepared to read the receive level of a sat-nms beacon receiver through the
TCP/IP interface.
The flexible interface design of the ACU enables it to control most types of motor driving
antennas for geostationary satellites. Supported motor controllers are (configurable in the
field):
Power relays: This simple solution is suitable for antennas using 2-speed AC motors.
Freque ncy inv erters: Speed and acceleration ramps are programmed into the inverter
module with this solution.
Servo controllers: Used for DC motors at small antennas. Supported position sensors are
(separate hardware interface modules for each axis:
Resolver Interface: The resolver interface module contains a resolver to digital chip which
does the decoding of the resolver sin/cos signals.
SSI Interface : SSI is a high speed serial interface used by modern digital position encoders.
DC Voltage Interface: The third position encoder interface module contains an A/D
converter which is suited to measure the DC voltages produced by simple inductive angle
encoders. This application is for small antennas especially in the SNG business.
The paragraphs below give a short overview to the contents of the documentation. A subset of
this documentation is stored on the device itself, the complete documentation is available on the
sat-nms documentation CD and at www.satnms.com .
Safety Instructions : This chapter gives an overview about the safety precautions that have
to be observed during installation, operation and maintenance.
Unit Overview : The installation chapter gives informations about the different modules that
are integrated in the ACU (not ACU-ODM and ACU19).
Installation/Start-up : The installation chapter guides through the installation and setup of the
ACU outdoor module. It describes the mechanical concept of the ACU and the assignment of
the ACU's connectors. It gives you informations about the starting up procedure. Finally you
learn in this chapter how to set the ACU's IP address, which is a essential precondition to
operate the ACU by means of a web browser.
Operation : The sat-nms ACU is operated using a standard web browser like the Internet-
Explorer on MS Windows based computers. The user interface design is straight forward and
clearly structured. Operating the ACU is mostly self-explanatory. Nevertheless, the
(C) 2022, SatService GmbH www.satnms.com ACU-ODU-DC-UM-2209 Page 5/67

'Operation' chapter outlines the map of web pages which make up the ACU user interface
and elaborately describe the meaning of each alterable parameter.
Frontpanel Operation : The sat-nms ACU19 and the sat-nms ACU-RMU optionally are
equipped with a frontpanel Human-Machine-Interface. This chapter describes how to use this
interface.
Remote Control : The ACU outdoor module provides a versatile remote control interface. A
monitoring & control software may fully operate the ACU either through a TCP/IP network
connection or through the RS232 interface of the ACU. This chapter describes the
communication protocol used for remote control and lists all parameters accessible through
the remote interface.
Theory of Operation : This chapter gives a short overview how the ACU works. It also
describes the different tracking algorithms and their parameters. The interaction with a
beacon receiver is described as well. Knowing about the theory regarding this functions
helps to find the best parameter settings for a given application.
Specifications : At the end of the document, the specifications applicable to the sat-nms ACU
are summarized in this chapter.

protective wire, inside or outside the sat-nms ACU, is likely to make the unit dangerous.
Intentional interruption is prohibited.
The unit described in this manual is designed to be used by properly-trained personnel only.
Adjustment, maintenance and repair of the exposed equipment shall be carried out only by
qualified personnel who are aware of hazards involved.
Refer servicing to qualified personnel.
To prevent electrical shock, do not remove covers.
For the correct and safe use of the instrument, it is essential that both operating and servicing
personnel follow generally accepted safety procedures in addition to the safety precautions
specified in this manual.
(C) 2022, SatService GmbH www.satnms.com ACU-ODU-DC-UM-2209 Page 6/67

Whenever it is likely that safety protection is impaired, the unit must be made in-operative and
secured against unintended operation. The appropriate servicing authority must be informed. For
example, safety is likely to be impaired if the unit fails to perform the intended measurements or
shows visible damage.
Ensure that the cabinet is proper connected to the protective earth conductor.
The circuit breaker, that fuses the mains for the sat-nms ACU has to switch off all phases AND the
neutral wire as well.
WARNINGS
The outside of the equipment may be cleaned using a lightly dampened cloth. Do not use
any cleaning liquids containing alcohol, methylated spirit or ammonia etc.
Follow standard Electrostatic Discharge (ESD) procedures when handling the Unit.
Apply the appropriate voltage according to the attached schematic.
In case of switching off all the circuit breakers is still voltage available at the mains terminals!
Only use shielded cable to connect the AZ- and EL-Motor. The other components in the
cabinet might be jammed through the harmonic waves the frequency inverters inject into the
motor wires.
Use only double shielded twisted pair cables (e.g. CAT7 Ethernet cable) to connect the
resolvers to the sat-nms ACU
Only ACU-ODU : If the Unit is equipped with an optional air ventilation, avoid direct contact
with jets of water, normal rain is no problem.

(C) 2022, SatService GmbH www.satnms.com ACU-ODU-DC-UM-2209 Page 8/67

In the ACU-ODU you find 2 power supplies: one is for the core processor of the ACU-ODM, it is
labelled with PS ODM. The other one supplies the external contacts of the ACU e.g. the control
signals for the POL drivers relais. This one is labelled with 'PS EXT'. By this, the core processor
of the sat-nms ACU-ODM will not break down if something externally happens (e.g. overload/
short circuit)
3.3 Power supply for motor drivers
As standard type a 24VDC/10A power supply is installed for the motor drivers. On demand
versions with up to 48VDC/15A are available. To provide enough power for starting up the
motors, there is an additionally 15000uF capacitor integrated (3a).
3.4 Motor drivers
Depending on your requirements up to 3 motor drivers are integrated into the ACU-ODU. These
are DC power drivers with power rating of 15A. The standard version has a voltage rating of
35VDC, an extended version for 48VDC is available on demand. The standard power supply
integrated into the sat-nms ACU-ODU is 24VDC/10A, so this is the limiting value. On demand, the
sat-nms ACU-ODU is available with a power supply that provide higher current.
the following picture shows a DC driver
On the upper side, you see the control inputs, on the lower side the power input and motor output
