2.2 Sub-band Channel Assignment – SATELLINE-M3-TR1 869
2.2.1 Sub-band
Each sub-band is defined by a start and stop frequency. Furthermore the maximum allowed
power level and maximum duty cycle is defined separately for each sub-band.
2.2.2 Duty cycle
The purpose of the duty cycle limit is to ensure that no single application can occupy this license-
free band for more than a certain percentage of time. The term duty cycle defines the percentage
of a 1-hour period a single modem is allowed to transmit. The modem limits the duty cycle itself.
Duty cycle is limited by the firmware by adapting to the transmitted data. The absolute maximum for
a transmission is 1 second after which the transmitter is switched off.

sub-band is pre-programmed into the SATELLINE-M3-TR8. The user can choose from 10, 20, 50,
100, 200 and 500 mW ERP* output power for frequency variant 868…870 MHz and for Indian
frequency variant 865…867 MHz following power levels: 10, 20, 50, 100, 200, 500 and 1000 mW
ERP*. No matter what power level the user has chosen the maximum allowed power level of the
chosen sub-band cannot be exceeded.
*ERP = The effective radiated power from the antenna relative to a half-wave dipole in a certain
direction.
2.2.4 Channel assignment
Each sub-band is divided into 25kHz channels according to a channel assignment scheme defined
by the recommendation CEPT/ERC/REC 70-03.
The subband settings for EASy 869 and TR1 869 (868…870 MHz versions) are by default:
Active subband: Subband1
Subband1: 869.4000 –869.6500 MHz, 500 mW, 10 % duty cycle
Subband2: 869.6500 –869.7000 MHz, 25 mW, 10 % duty cycle
Subband3: 869.7000 –870.0000 MHz, 25 mW, 1 % duty cycle
Subband4: 869.7000 –870.0000 MHz, 5 mW, 100 % duty cycle
When the user selects the active subband, RX/TX frequencies will also switch to Subband Min
Freq+12.5 kHz (for example 869.4125 MHz for Subband1).
Note. The active subband can be selected by using SL command SL&B= or selecting on the
programming menu. SATEL Configuration Manager (current version 1.4.5) does not support the
subband settings yet.
CTS line indicates the duty cycle. Any transmitted data appearing at the serial port outside the
duty cycle period is ignored.

3INTERFACE – CONNECTORS & LEDS
3.1 Antenna connector
SATELLINE-M3-TR1 and SATELLINE-M3-TR1 869 have a HIROSE compatible 50 Ohm U.FL male
antenna connector on the printed circuit board with impedance of 50 Ohm.
An external antenna is connected typically by using a female U.FL to TNC, MCX, MMCX or SMA
pigtail adapter. In case the antenna load is not 50 Ohm, the impedance matching should be
placed in the host application.
The antenna should always be connected when the power is on. Removing the antenna while
the transmitter is on may damage the power amplifier inside the transmitter.
3.2 Power supply
SATELLINE-M3-TR1 is available in two operating voltage ranges depending on which type of
internal power/interface-module has been installed at the factory. The voltage range is marked
on the label:
•+6…+30 VDC (delivered by default)
•+3…+9 VDC
SATELLINE-M3-TR1 869 is currently available only in +6…+30 VDC operating voltage range.
The radio modem must be connected to a power supply with an adequate current output.
A proper fuse should be connected in between the radio modem and the power supply:
Operating voltage range
+3 … +9 V
+6 … +30 V
Current rating of the fuse
2.5 A slow
1 A slow
Operating voltage range of SATELLINE-M3-TR1 is marked as follows:

3.3 Serial ports
Before connecting DTE (Data Terminal Equipment) to the radio modem, please make sure that
the configuration matches the physical interface (electrical characteristics, timing, direction and
interpretation of signals). The radio modem contains two separate serial ports that are
designated as Port 1 and Port 2. Only one port at a time can be selected for communication.
Port 1 - Always RS-232 (Port 1 ON is the default configuration)
Port 2 –The physical interface depends on which type of internal power/interface-module has
been installed at the factory. Available options are:
•RS-232/RS-422 (delivered by default)
•LVTTL
•TTL
RS-422 interface of the radio modem can be adapted to RS-485 interface by wiring the signals
externally, see paragraph RS-485 interface.
3.4 LED indicators
There are two LED indicators on the printed circuit board that indicate the status of the serial
port and the radio interface:
