1 Introduction
T he sat-nms Radiometer Controller (RMC) is a controller for radiometers. It is not only for use as core
module for new radiometers in any frequency band, but also to upgrade existing radiometers. It was
developed by SatService GmbH including a highly linear sat-nms Radiometer Detector (RMD) for the
detection of the noise signal in any IF band between 50 and 2000MHz.
The chosen radiometer concept provides high stability and measuring accuracy and easy and flexible
operation due to operator friendly user interface.
The radiometer type implemented is noise balancing / noise injection. In addition to that the software
includes all other additional functions necessary for a radiometer, for example control functionality for
azimuth and elevation of the radiometer antenna. This allows automatic tip curve calibration and automatic
calibration with a cold-load via sat-nms RMC. Also the complete high precision temperature control of the
feed box, including the microwave and IF receiving system, is performed via the radiometer controller.
Like any equipment belonging to the sat-nms family, the radiometer controller provides an Ethernet TCP/IP
interface. All measurement results and the monitoring parameters are available via HTTP Web Interface and
can be monitored and controlled from remote IOT software either via HTTP get functions or via RS232
interface. The controller includes a compact flash card of 2GB for data logging purposes and allows
download of data via FTP.
This document is the user manual provided with the sat-nm s RMC. It contains all necessary information
how to install, setup and operate the radiometer. The user manual is available as a printed document and for
on-line reading on the radiometer itself as well.

Version 1.7 / 2011-02-20
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-nm s
documentation CD and at www.satnms.com.
Installation: The installation description is available at the printed version of the manual only. This is
due to memory restrictions of the radiometer. Look at http://www.satnms.com/doc/html/radiometer/ for
a full version of this manual.
Operation: The sat-nms RMC 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 sat-nm s RMC is mostly self-explanatory. Nevertheless, the 'Operation' chapter outlines
the map of web pages which make up the sat-nms RMC user interface and elaborately describes the
meaning of each alterable parameter.
Remote Control: The radiometer provides a versatile remote control interface. A monitoring & control
software may fully operate the radiometer either through a TCP/IP network connection or through the
RS232 interface of the radiometer. This chapter describes the communication protocol used for remote
control and lists all parameters accessible through the remote interface.
Theory of Operation : For a detailed description please refer to the sat-nms documentation CD or

2 Installation
This chapter describes how to install the sat-nms Radiometer Controller (RMC). You find a guide how to
connect, configure and mechanically mount the RMC below.
Before you start, please first read the Safety Instructions chapter below. It contains some important
recommendations to prevent damage from the RMC.
Then, we strongly recommend to do a first setup of the RMC on a lab desk before installing it at it's final
location. This is mainly for the following reason:
To setup the RMC IP parameters, the PC used for configuring and the RMC must either be connected to
the same Ethernet hub or must be connected directly with a crossover cable. The initialization program does
not work through routers or intelligent network switches.
Hence, the typical sequence of tasks when putting a sat-nms RMC outdoor module into operation is as
follows:
1. Read the chapter Safety Instructions.
2. Set the RMC IP address.
3. Mechanical mount the RMC.
4. Connect the RMC at its destination environment. Finally connect the power supply and the Ethernet
network.
2.1 Safety Instructions
Failure to observe all Warnings and Cautions may result in personnel injury and/or equipment damage not
covered by the warranty.
Follow standard Electrostatic Discharge (ESD) procedures when handling an sat-nms RMC.
Select and apply the appropriate 24V D/C voltage according to the data sheet before connecting power.
Before connecting the sat-nms RMC to other devices, ensure that these devices can handle the voltage
provided by sat-nms RMC.
The sat-nm s RMC can be damaged if the input voltage is higher than the specified maximum value.
Don’t connect a heater without the corresponding Temperature-Sensor. If you don’t connect a
Temperature-Sensor, the Temperature regulation in the sat-nms RMC is going to switch on the heater
permanently until the regarding temperature-switch turn off the heater.
Move an antenna only with connected end switches.

In case of a failure do not open the sat-nms RMC enclosure, you will lose warranty. Call SatService
GmbH for an RMA number.
Observe normal safety precautions when operating, servicing, and troubleshooting this equipment.
Take standard safety precautions with hand and/or power tools.
2.2 Setting the IP Address
Before you can operate the RMC, you need to set the RMC’s IP address. There is a special configuration
program on the documentation CD shipping with the RMC for this purpose. We recommend configuring the
RMC TCP/IP settings before you install the RMC at its final place. To configure the RMC, the following
equipment is required:
The sat-nm s RMC outdoor module itself.
A 24V D/C power supply.
A Computer running a Microsoft Windows operating system equipped with CD-ROM drive and
Ethernet network card.
A CAT5 crossover network cable or a Ethernet hub and standard network cables to connect the RMC
and the computer.
The CD-ROM shipping with the sat-nm s RMC.
Setting the RMC IP parameters now is easily done within a few minutes.
1. First install a network cable between the RMC and your computer. If you have a crossover cable
available, this is very easy: simply put the cable into the network connectors of computer and RMC.
Without a crossover cable, you need to connect both, the computer and the RMC to the same network
hub using two standard network cables. It is essential, that the computer and the RMC are connected
to the same network segment, the configuration program is not able to find the RMC through routers
or network switches.
2. Now power on your computer and connect the RMC to the 24V D/C supply.
3. Insert the CD-ROM into the computer's drive and inspect its contents through the 'My Computer' icon
on your desktop. Double-click to the 'ChipTool.exe' program in the 'ChipTool' directory.
4. When the ChipTool program is running, type CTRL+F to make the program search the RMC. The
program shows a list containing at least one entry describing the actual network parameters of the
RMC.
5. The serial number shown in the first column of the list, must match the serial number printed on the
RMC enclosure. If the list stays empty, the RMC is not connected properly. If there are more entries in
(C) 2020, SatService GmbH www.satnms.com RMC-UM-2002 Page 6/47

the list, the configuration program has found other devices in this network segment which use the same
technology.
6. Now type CTRL+I to open the IP configuration window of the program. In this form enter the RMC
serial number, it's new IP address and network mask. If the RMC later shall be operated through a
router, enter the address of the router on the gateway field, otherwise leave this field blanc. Be sure,
that the 'DHCP' mark is unchecked. Finally click to the 'Yes' button to set the new parameters at the
RMC.
Now the IP configuration of the RMC is completed. You may finally want to test if the RMC is reachable
now. Start your web browser and type the RMC IP address into the URL field of the browser. The RMC
should reply with its main page, provided that the RMC and your computer are configured for the same
subnet.
2.3 Connecting the RMC
The sat-nms RMC provides a lot of input/output signals. They all are described in the following chapters.
Some applications do not require all ports of the RMC to be cabled.
When connecting and configuring antenna control unit (position sensors and motor drivers), the following
sequence of items is recommended:
1. Connect the position sensor, but not the motor driver.
2. Configure the RMC for the correct type of position sensor.
3. Move the antenna a small amount in both directions (you need to command the motor driver directly,
e.g. using bridge circuits), verify that the angle changes in the right direction.
4. Enter a calibration offset which lets the RMC show an angle which matches the (roughly) estimated
position of the antenna.
5. Now connect the motor driver to the RMC.
6. At the 'Test' page, activate the motor driver outputs for a short time; verify that the antenna moves as
expected.
2.3.1 Connector Layout
Below the connector layout of the sat-nms RMC is shown. Except the network connector which is a
standard 10-Base-T Ethernet socket, all connectors are Phoenix Contact Combicon plugs / clamps. Pin 1 of
each connector is the right-most if you look at the screws of the connector.
