Introduction
This operator manual serves as the primary document for familiarising users with the parameters of
the radio modem MX160, its properties, modifications and with the parameters of connecting parts.
This controller is part of the MORSE system, is fully compatible with other modems, and because it is
derived from previously developed types it has similar mechanical parameters to them, as well as all
interfaces, the modem part and firmware. For this reason modem MR400 images are often used in
other parts of the manual. In order to master all the functions of the radio modem and the MORSE
system you should refer to other documents.

Introduction

1. Radio modem MX160
MX160 is conceptually new radio modems designed for transmitting data in the VHF and UHF bands.
The radio modem uses 2-state GMSK modulation providing for a maximum signalling rate of 133 kbit/s.
The radio modem is of modular design with one to four standard RS232 ports (an RS422 or RS485
port can be used in place of two of them) available to the user. The configuration can be extended by
an Ethernet interface and also by a module with analog and digital inputs/outputs and GPS modul. It
is generally manufactured with two analog inputs and outputs and with two digital inputs and outputs.
The radio data transceiver module can be configured to a random frequency of the transmitter and re-
ceiver in the 3.2 MHz frequency range in a 25 kHz channel raster. The output and input working fre-
quencies are mutually independent and are derived from the frequencies of four phase-hung systems
programmed by the transceiver microprocessor. Channel settings are stored in the transceiver FLASH
memory and the FLASH memory module of the modem whose communication processor controls the
operation of the transceiver microprocessor. The power of the radio modem transmitter is digitally set
in sixteen steps from 0.1 to 25 W.
The design and construction of this device allows for long-term loading and for this reason it is
primarily determined for continuously running applications.
Software control is compatible with the operation and configuration of the other radio modems of the
MORSE system. A description of software control and configuration of the radio modems is available
in publications describing MORSE Firmware.
Important
The radio modem is equipment which can only be operated in the state on the basis of
Permission to operate transmitting radio stations issued by the Department of Frequency
Spectrum Management at the national Telecommunication Office.

2. Description of Radiomodem MX160
2.1. Radio part
The architecture of MX160 radio modems resolves most of the requirements placed on a top quality
user friendly radio modem with a very short switching time between receiving and transmitting. Frequency
synthesis enables operation on any random channel from a given frequency band. The operation of
the radio data transceiver module is controlled and diagnosed by the micro-controller. The receiving
part of the radio modem works with double mixing. Concentrated selectivity is divided between both
intermediate frequency levels. The first filter carries out basic channel pre-selection up until attenuation
which ensures the linear function of the following second mixer and intermediate frequency amplifier.
The second filter of concentrated selectivity has an attenuation characteristic necessary for channel
selection in the used channel spacing of 200 kHz. Logic circuits, switching stations between modes of
receiving and transmitting, have high noise immunity and switch respective blocks sequentially. This
minimises most transient parasite states and optimises bandwidth during switching. Station block modes
are logically tied and switching of the station to transmitting mode is tied to the frequency synthesiser
lock, the internal temperature of the radio transceiver module and the value of the supply voltage.
2.2. Modem part
The control microcomputer has 4 MB of FLASH memory and 16 MB of RAM memory available. The
battery, real time backup supply, detector of supply voltage failure and watch dog circuits belong
amongst the other circuits of this block. If there is a supply voltage failure the fact is recorded into
memory with the respective time data thanks to the charge stored in electrolytic capacitors. The user
therefore has information available about the time and duration of possible faults caused by power
failures. It is possible to connect equipment with signalling rates up to 115.2 kbit/s to the modem via
the RS232 data interface. RS232 interface converters are protected against overvoltage with TRANSIL
elements. A lithium battery is used for backing up in the modem part.
Note
Owing to the use of lithium batteries in the modem part it is not recommended to store them
for a period of longer than 2 years.
2.3. Supplying
The radiomodem is supplied by the DC current 13.8 V. The consumption in the quiet state is from 350
to 500 mA according to module used, the consumption at transmitting is up to 2 A. The modem can
be set in the SLEEP mode when the consumtion drops down to 2.5 mA. The return in the active mode
can be done by the signal inputting on the serial port or after a preset time.
2.4. Radio Modem Assembly
Radio modems MX160 are special devices which require skilled assembly. All supplied equipment is
assembled by RACOM at the user’s site. For subsequent maintenance RACOM specially trains the
user’s skilled staff and as an additional aid provides them with Operating regulations for radio data
networks and MORSE Firmware – Documentation.

Description of Radiomodem MX160

3. Connectors
3.1. Antenna
The radio modem is fitted with two SMA type connectors for connecting an antenna. The connector
labelled Rx is for the receiver, and Tx for the transmitter (up to 25 W). Use the corresponding type of
connector with matched impedance as the mate. We recommend an RG158 cable for the serial lead.
Important
The radio modem cannot be connected to the power supply without the antenna connected
(or corresponding artificial load). Otherwise this could lead to damage to the radio part of
the modem.
3.2. Serial Interface
The radio modem can be equipped with serial ports RS232 or RS422/485, the ports can be optical
isolated. According to the configuration of the radio modem it is possible to use a terminal block or
DSUB 9 (Canon) connectors for connecting data cables via the serial interface. See Chapter Labelling
modems.

Note
For data connector RS485 connection see Table of data connector RS422 connections.
Important
For making data cables for connecting the user´s terminal equipment to the modem´s serial
port we recommend using a shielded cable, particularly in an industrial environment, and
connecting the shielding to GND (pin No. 5). When using a multi-core cable all free conduct-
ors should be connected to pin No. 5. In the case of a galvanically separate port for RS485
(RS422) only ground one side of the data cable. We recommend using only the necessary
minimum length for data cables.
3.2.2. Distinguishing Data Modules by Colour
For RS232 RxD is the output from the radio modem (approx. -8V when inactive) and TxD is the input
to the radio modem (according to the RS 232 standard). Hardware versions of the interface can be
distinguished according to the colours of LED diodes next to the connector.

The SCC ports of the radio modem are DCE type devices. Based on standards the receiver terminal
RxD of the connected DTE device is connected to the transmitting terminal of the modem's SCC port
which is also labelled RxD. Similarly the red LED indicating transmission from SCC is labelled RxD.
3.3. Ethernet
• Connector RJ-45 for Ethernet 10BaseT and 100BaseT corresponds to the EIA TIA T568B standard.
• Informative LED diodes indicate:
• Tx – output from ETH channel
• Rx – input to ETH channel
• 100 – if lit the 100Base-TX net is indicated otherwise is 10Base-T
• LINK – indicates correctly connected link
• F.D. – indicates full duplex operation
• The direct cable serves for connecting to the Ethernet network via the hub (repeater) or switch-hub
(router).
• A crossed cable serves for connecting only two devices - MR400-MC100, MR400-PC, etc.
The following table contains connector connections and colours of conductors. For the crossed cable
the order of conductors on one side is the same as for the direct cable.

The MR400 radio modem used in the diagram showing examples of wiring can, of course, be replaced
by any MORSE system modem. (e.g. MD160, MX 160, MWxxx, MRxxx, MC100, ...)
3.5. M-BUS module
(Meter-Bus)
Use
The M-BUS board serves as the MASTER interface of the physical layer of the M-BUS for the application
of data collection from meters regulating the consumption of various types of media (water, gas, heat,
etc.).
A M-BUS module can be positioned in the first or second slot of optional modules, see section Sec-
tion 3.11, “View of Radio Modem”. (For MG100 only in the first slot.) The second slot is recommended
because when using slot 1 you first need to disconnect it in the modem´s service mode, see section
Section 3.10, “Service Connector”.
For the correct operation of the module it needs to be configured to the proper SCC in menu SPe using
Setr:
dia(g) mode : NORM
pr(o)tocol : L&G 870-5-2 IEC
Wideband modems – PROFI MX160 – © RACOM s.r.o.14
Connectors

Note
For configuration of the menu using program Setr see „MORSE firmware documentation1“
A supply voltage can be applied to the board via the MR400 supply connector. In this case simply
connect a wire with a positive voltage. When supplying from an external power source both leads need
to be connected.

3.7. T-port
(Ethernet to serial)
Use
The Ethernet interface is mounted with a standard RJ45/STP connector. This interface is an Ethernet
(TCP, UDP) to RS232 serial interface converter.
The module automatically set communication to a speed of 10 or 100 Mbit/s according to the speed of
the network to which it is connected.
3https://www.racom.eu/eng/support/firmware/mr400/index.html
17© RACOM s.r.o. – Wideband modems – PROFI MX160
Connectors

The T-port module can be positioned in the first or second optional module slot, see section Section 3.11,
“View of Radio Modem”. (Or only in the first slot for MG100 modems.) The second slot is recommended
because when using slot 1 you need to take into consideration the fact that it needs disconnecting
when the modem is in service mode. For more detailed information see section Section 3.10, “Service
Connector”.
T-port parameters are set up for communication with attached devices using a web browser. If the T-
port IP address is unknown it can be found using program DigiConf from Digi4.
Attached devices send TCP/UDP frames from which data packets are generated after unpacking in T-
port. Based on the format of these packets a suitable serial link protocol can be selected and they can
be configured on the SCC using Setr. The standard setting for configuration parameters is 9600, 8

3.10. Service Connector
The service connector RJ-12 serves for short-term connections of the service cable during local adjust-
ment of radio modem parameters. Upon attaching the connector (connecting to the RS232 link (RxD,TxD,
GND)) the radio modem automatically switches to service mode and the module slot 1 disconnects.
