4.4 VCC_IO pin
VCC_IO pin determines the voltage level of UART signals and the voltage level of GPIO output
signals. VCC_IO level also determines GPIO LOW/HIGH levels on each GPIO and UART input
pins.
4.5 Service pin
The SERVICE pin is used to set the UART1 into a known state. Pulling this pin LOW will activate
the service mode and set the UART1 into 38400, 8, N, 1. This is intended for service access of
the module, to have a known serial port setting in order to provide easy access to module settings.
The pin does not affect any permanent settings, nor does it change the mode of the module. It is
recommended to pull high or pull up by resistor to VCC_IO to return serial port 1 into the
configured state. When service pin is LOW the SL Commands are temporary forced to be ON
4.6 Stat pin
SATELLINE-M3-TR8
SATELLINE-M3-TR9
Integration Guide, Version 1.9
23
The STAT-pin indicates the status of the device. It can be used to drive or sink a LED current using
a proper series resistor. STAT-pin drive or sink capability is +/-10mA at 3.3 V. It is recommended
to use VCC_IO for LED current.
Notice that if STAT-pin is used to sink LED current, LED behavior is opposite to driving scheme.
The behavior of the STAT pin is described down below.
Modes of STAT pin:
Blink cycle
Mode
“1” - statically
Module is operational “searching for a new frame”
“0” for the endurance of the
received frame.
“0” when module is receiving data from air interface.
In practical cases will toggle at the frequency of the data
packets on the air interface.
“0” statically
Module is in sleep1 mode
The pin is toggled in transmission

Module is sending data Over the Air
Pin is toggled in 1 s interval
Module has the connection to Configuration Manager
program.
Pin is toggled in 500 ms interval
SL command mode set to OFF and SL commands enabled
using “+ + +” sequence, section 7.2.
Pin is toggled in 250 ms interval
Module has detected a fault, fault codes can be read via
Configuration Manager program.
4.7 VCC pins
VCC pins are to feed operating voltage to the module. Limit for this voltage is mentioned in
chapter 2.2 DC electrical specifications. User must take into consideration surge current and
current consumption issues before using these pins. Also the user must be aware for any voltage
drop on the feeding path.
4.8 UART pins
Pins 7, 8, 9, 10 are used for UART serial transmission between the module and the terminal. The
UART signal level corresponds to the level in VCC_IO pin. VCC_IO pin must be fed with a correct
voltage level to match the terminal device.
4.9 GPIO pins
GPIO pins are reserved pins for future use or special applications or special features. Unused pins
should be left unconnected.
4.10 Antenna interface

The antenna interface is a 50 Ω coaxial connector. Matching networks are not included on the
module and should be placed in the host application if the antenna is not 50 Ω. The HIROSE
U.FL compatible connector is located on the TOP side of the board.
NOTE! The used connector has gold plated contacts - whereas a standard HIROSE U-FL has silver
plated contacts. If silver - gold joints are not allowed in your product, use gold plated cable-
connector to mate to this device.

5 MECHANICAL CONSIDERATIONS
5.1 Fixing device to host
The M3-TR8 / M3-TR9 radio transceiver module can be mounted on to the host application by
using spacers and screws. It is highly recommended to use conducting metal spacers and screws
to create proper electrical conductivity between the module and the host application.
Recommended materials for spacers include brass or aluminum and steel screws. User must take
care that there is no excessive mechanical stress created to the DTE connector while inserting and
attaching the module. Recommended maximum screw size is M3, minimum spacer height between
the module and the host application is 3 mm.
Figure 5.1 Example of module attachment to application PCB.
Since the module creates heat while operating, it must take into consideration to maximize the
heat transfer from the module to an external heat sink. Proper heat sinking methods could be
copper plated PCB, metal housing or a heat sink piece. The most recommended solution is to
use a metal conductor to transfer heat from the module to an external heat sink which dimensions
and location is adequate for a proper performance. To source the heat from the module is the
plain area next to the antenna connector shown in a figure 5.2. Heat can be conducted from
either side. To further improve the heat conductivity and reducing the heat transfer barriers, proper
heat conducting paste or heat conducting tape should be used.

Mode is entered when a fault has been detected and
the device has been Rebooted. In safe mode fault
codes can be read from the module (section 6.1).
Sleep mode

parts of the radio on, wakeup will take approx. 30 ms
Power Save
mode
Power save
Automatic sleep/wake-up procedure where module
sleeping time is dynamically adjusted to received data
packets. Decreases the power consumption of
complete receiving cycle approx. 30%.
6.1 Safe mode
When a fault has been detected by the Firmware, the module is set to Safe mode. In this mode
the module toggle’s the STAT pin in 250 ms interval indicating an Error and reboots the device
after 5 s. Transmitting/Receiving is prohibited during malfunction. When connecting to the device
with SATEL Configuration Manager the Error code is shown in pop up box. If the device does not
recover after multiple reboots, please contact SATEL Oy.
SATEL Configuration Manager can be downloaded from website https://www.satel.com/support-
and-services/downloads/ The version 1.5.1 or newer is compatible with SATELLINE-M3-TR8 radio
transceiver module.
6.2 Power up / power down scenarios
The transceiver module can be set in four (4) states, “ON”, “OFF”, “Sleep1” and “Power Save”.
When power is applied to the module, the module switches to ON state when voltage in
ENA_MOD is set to HIGH.
The module can be shut down by driving ENA_MOD line to LOW state. In the “OFF” state current
consumption is only that of leakage current from an LDO, section 2.3. In this state all non-essential
parts off the module are powered down and all settings/state information that are not stored in
nonvolatile memory are reset.

SATELLINE-M3-TR9
Integration Guide, Version 1.9

6.3 Sleep Mode
When being in sleep mode, the radio part of the module is switched OFF while the serial interface
communication related parts remain powered ON. The module will be automatically woken up
after the CPU senses a state change in the TD1 pin. Example: The module is in Sleep1- mode.
The module is woken up by sending a character or characters into the TD1 pin after which the
module responses “OK”. After “OK” the module is ready for normal communication.
To turn the module ON from Sleep1 mode:
1) Issue a state change to TD1 (toggle pin (minimum pulse duration time 10 µs) or issue a
byte on the UART (for example 0x00))
2) Wait for “OK” -response from the module. The wake-up time is approx. 30 ms.
3) Start communicating normally
Module will remain powered ON until a new sleep command is issued.
6.4 Power Save Mode
The Power save mode performs an automatic, self-adjusting receiver wake-up/sleep cycle.
It is designed for applications which base on one-way communication with relatively constant TX
interval and, in which the data packet separation is > 200 ms.
When enabled, the unit makes the transmission interval study basing on four (4) successfully
received data packets. The shortest time between transmitted packets is measured (t
min
). Measured
value is updated after each successfully received data packet, so that possible changes in the
message length becomes noted.
Ensuring that the complete messages will be received even if there occur little variation in
transmission interval, some safety margin (t
marg
) is left into Ready to receive from RF mode time.
Safety margin is calculated by dividing the shortest time between transmitted packets (t
min
, in ms)
with 8 and by adding 60 ms to this result:
t
marg =
t
min
8
+ 60 ms
The length of the whole sleeping period (t
sleep
) is calculated by decreasing the shortest time between
transmitted packets (t
min
) with safety margin (t
marg
) and transmission time of the original message
(t
TX
):
t
sleep
= t
min
− t

− t

Transmission interval study is started over always after 100 successful sleep/wake-up cycles and,
if the expected receiving slot (t
RX slot
) with enhanced overlap margin (t
overlap
) has been missed. In
latter case the package is considered to be lost.

6.5 Restart
After startup the module can be restarted by issuing a SL command, upon which the module will
shut down all circuitry, and Reboot the CPU (see SL command list).

7 CHANGING PARAMETERS USING SL COMMANDS
The controlling terminal device can change the configuration settings of the module. This is
accomplished with the help of SL commands. SL commands can be used to change the device
settings e.g. the frequency, addresses etc. SL commands can also be used to request setting values
from the module to the controlling terminal.
7.1 SL Commands
An SL command is a continuous string of characters, which is used to control the device and its
settings for example from the terminal screen (similar to AT commands).
Serial interface settings are the same as in data transfer, however, if SERV pin is set to LOW, baud
rate is fixed 38400, 8, N, 1. SL command is properly recognised also in the case when the
command string is terminated by <CR> (<CR> = Carriage Return, ASCII character no. 13,
Carriage Return, 0x0d in hex) or <CR><LF> (<LF>= Line Feed, ASCII char. no. 10, Line Feed,
0x0a in hex). No extra characters are allowed at the end of an SL command.
SL command is separated from other data by pauses which are equal or greater than time defined
by Pause Length-parameter (default = 3 characters) in the settings. If multiple SL commands are
sent to the module, the next command can be given after receiving the response ("OK" or "ERROR")
of the proceeding command. In addition, it is recommended to implement a timeout to the
terminal software for recovering the case when no response is received from the radio module.
The module will acknowledge all commands by returning an "OK" (command carried out or
accepted) or the requested value, or an "ERROR" (command not carried out or interpreted as
erroneous) message.
The SL commands are listed in appendix B.
7.2 SL Command Mode
The SL commands have always been enabled in the previous products like M3-R3. When the SL
commands are enabled there are possibilities that the user data may start with the characters “SL”
which is handled as the SL command. This has caused the firmware to go to the continuous SL
command search mode and any data has not been sent or even an “ERROR” acknowledgment
has been received. To avoid this kind of behavior the user can disable the SL commands. The SL
commands can be disabled or enabled using the “SL Command mode” parameter. The user can
do this via the SATEL Configuration Manager, version v1.5.1 or newer.
By default the SL Command mode is set to ON. If the SL Command mode is set to OFF then the
SL commands can be enabled or disabled using the following procedures:
To enable the SL Commands:
Send three “+” characters via serial port so that there is at least three bytes delay
between each character. The response is “OK”, when successfully set.
SATELLINE-M3-TR8
SATELLINE-M3-TR9
Integration Guide, Version 1.9
31
<+><at least three bytes pause><+><at least three bytes pause><+>
To disable the SL Commands:
Send three “-” characters via serial port so that there is at least three bytes delay between
each character. The response is “OK”, when successfully set.
<-><at least three bytes pause><-><at least three bytes pause><->
Note!
The “+ + +” and “- - -” procedures are not allowed to be used, when radio is transmitting or
receiving data (i.e. the application data occupies the TD or RD lines of the radio).

10 CONSIDERATIONS
10.1 EMI Interferers
The module is designed to be mounted inside a host device. The module is designed to withstand
EMI even beyond type approval requirements. However, a small module which is integrated closely
to modern high speed electronics is bound to receive some interference.
To make a working integration, consider the following: EMI can enter the module in four ways:
1) Via the antenna (radiation from enclosure enters the antenna)
2) Radiated disturbances to the coaxial cable
3) Radiation from other electronics / cabling directly to the module
4) Conducting through the DTE interface (power, control and data lines).
Because the module is shielded and the DTE interface is filtered, the usually worst method of
disturbance is via the antenna port, which is easily overlooked in design. Keep in mind that the
radio module has a sensitivity of approx. -107 dBm (depends on mode of operation and speed
etc.). While the module has an approx. 10 dB S/N requirement, this constitutes, that any signal
entering the radio antenna on receive frequency on a level of higher than -117 dBm (-107 dBm-
10 dB), causes desensitization of the radio on that particular channel.
Example:
An interferer has a level of -100 dBm at the frequency 869 MHz. The radio will show an
approximate sensitivity of -90 dB (-100 dBm + S/N requirement 10 dB) at 869 MHz.
Now consider that generic EMC requirements usually have pass/fail criteria of -57 dBm (if
normalized to the surface of the device). So there is almost a 60 dB gap between generic EMC
requirements and co-existence requirements between a high sensitivity narrowband radios.
To avoid problems of co-existence a good design should apply:
1) EMI shielding in enclosure – ambient air interface
2) Careful layout
3) Shielding of all digital high speed parts and cables
4) Have a clocking plan to avoid clock frequencies causing harmonics on
the UHF band of interest.
10.2 Electrostatic discharge
As the module is intended to be embedded in a host application, in a typical use case, the antenna
port is the only port of the module directly interface with a surface or contact area subjected to
Electrostatic Discharge (ESD). Thus, the antenna port is the only interface with high level ESD
protection. The DTE port also features ESD protection diodes, but is not designed to withstand
similar performance as expected from standalone units with enclosures.
SATELLINE-M3-TR8
SATELLINE-M3-TR9
Integration Guide, Version 1.9
35
Consequently, the module should be subject to ESD handling precautions that typically apply to
ESD sensitive components. Proper ESD handling and packaging procedures must be applied
throughout the processing, handling and operation of any application that incorporates this
module.
10.3 Using the device in unmanned high reliability applications
The module features software and hardware watchdogs which are incorporated inside the CPU.
While we believe that this is a reliable method of keeping the module in operational condition,
there are parts of the module that can’t be monitored for proper operation to 100%. For example
the module chip has a firmware that resides in the chips RAM. The firmware can’t be read back
or reloaded, without interrupting reception. Hence the module can’t reload this automatically by
itself without causing breaks in communication. To avoid the module from ending up in a state
where for example the module chip firmware is corrupted for example by ionizing radiation, it is
recommended that the controlling system implements some form of watchdog function for the
module. This can be done for example if the system knows that data should be received every
second, and no data has been received for a minute – then do a module restart using the
ENA_MOD pin or by issuing a restart command, or a cold boot by toggling VCC_IN low and
high again.

11 APPENDIX A
11.1 Sub-band Channel Assignment – SATELLINE-M3-TR8
11.1.1 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.
11.1.2 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.
11.1.3 Power level
The power level limit is defined separately for each sub-band. The maximum power limit for each
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.
11.1.4 Channel assignment
Each sub-band is divided into 25 kHz channels according to a channel assignment scheme
defined by the recommendation CEPT/ERC/REC 70-03.
