Description of the product
The SATELLINE-M3-TR3 is a UHF radio transceiver module, which transmits and receives data
from UHF transmissions made by SATELLINE-3AS family and similar transmitters.
The module is designed to be as compact and power efficient as possible. It has been developed
to be especially suitable for integration into battery powered and space constrained host
applications benefiting from UHF communications.
The module transmits and receives data via the Air interface (Ant. Connector, RF), modulates and
demodulates, encodes and decodes the data and sends the received data payload to the DTE
port. The DTE interface is used to provide power to the module and communicate with the
module.

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 e.g. the
frequency or addresses. It is also possible to ask the radio transceiver module to show current
settings which are in use.
3.1
SL Commands
An SL command is a continuous string of characters, which is separated from other data by
pauses which are equal or greater than time defined by Pause length parameter (default=3
characters) in the set-up. No extra characters are allowed at the end of an SL command.
Serial interface settings are the same as in data transfer. SL command is properly recognised also
in the case when the command string is terminated by <CR> (=ASCII character no. 13,
Carriage Return, 0x0d) or <CR><LF> (<LF> = ASCII char. no. 10, Line Feed, 0x0a). 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 transceiver 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, pages 26.
3.2
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 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 v1.3.15 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:
SATELLINE-M3-TR3
Integration Guide, Version 1.2
13
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.
<+><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).

OPERATING MODES
The radio transceiver module has the following modes of operation:
Mode
Function
Description
Ready to receive
from RF
Search for sync
Module is searching for the start of a radio
transmission from the RF signal.
Receive data
The module has found a valid radio transmission and
is receiving data.
TX
Transmit
The module transmits
Safe mode
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.
Sleep mode
Sleep1
Will turn the module into a state where it will hold
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%.
4.1
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 250ms interval indicating an Error and reboots the device
after 5s. 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 www.satel.com/downloads.
The version 1.3.15 or newer is compatible with SATELLINE-M3-TR3 radio transceiver module.
4.2
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 pin is >1.2V.
The module can be shut down by driving ENA_MOD line to <0.2V.
In the “OFF” state current consumption is only that of leakage current from an LDO (0.34 mA).
In this state all non-essential parts off the module are powered down and all settings / state
information that are not stored in NVM are reset.
SATELLINE-M3-TR3
Integration Guide, Version 1.2
15
4.3
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.
4.4
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 (tmin).
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 (tmarg) is left into Ready to receive from RF mode time.
Safety margin is calculated by dividing the shortest time between transmitted packets (tmin, in ms)
with 8 and by adding 60 ms to this result:
tmin8+ 60 ms
The length of the whole sleeping period (tsleep) is calculated by decreasing the shortest time
between transmitted packets (tmin) with safety margin (tmarg) and transmission time of the original
message (tTX):
tsleep= tmin − tmarg − tTX
SATELLINE-M3-TR3
Integration Guide, Version 1.2
16
Transmission interval study is started over always after 100 successful sleep/wake-up cycles and,
if the expected receiving slot (tRX slot) with enhanced overlap margin (toverlap) has been missed. In
latter case the package is considered to be lost.
toverlap = tmarg + 100 ms

Figure 4. Power save mode timing factors.
E.g. In system with TX interval of 1 s, and with 300 ms (approx. 300B @ 9600 bps) transmission
time:
tmin = 1000 ms
tTX =300 ms
tmarg =125 ms + 60 ms = 185 ms
tsleep= 1000 ms − (125 ms + 60 ms) − 300 ms = 515 ms
tRX slot, min = 1000 ms – 185 ms = 815 ms
tRX slot, max = 1000 ms + 285 ms = 1285 ms
4.5
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-list).

TIME PARAMETERS FOR STARTUP AND SHUTDOWN
SEQUENCES
Parameter
Recom. Time (*
Explanation
Tvic
Input capacitor
charge time
>50µs
When voltage is applied to VCC_IN the filter
capacitors inside the module are charged,
creating a small current surge. If the feeding
power supply is not very strong it is
recommended to wait this time before rising
ENA_MOD to minimize current surge.
Tioen
IO module start
time
<18ms
ENA_MOD enables the LDOs feeding the
FPGA and CPU inside the module. It is
recommended to apply VCC_IO voltage
within 18ms after ENA_MOD is applied.
Tiovs
IO voltage
startup time
<1ms
It is considered good design practice to KEEP
all IO signals (except ENA_MOD) low or
floating until the internal parts of the module
have power and the IO voltage is stable.
Tior
IO drive fall
time
< 300 µs
It is considered good design practice to set all
IO signals (except ENA_MOD) low or floating
before starting to shut down the transceiver
module. This way any latch up/brownout
problems can be avoided. IO-pins are not
internally driven after Tior.
Tldof
LDO discharge
time
> 300 µs
To avoid any possibility of reverse biasing of
regulators inside the module, it is considered
good design practice to use ENA_MOD to
shut down the regulators before deactivating
VCC_IN.

The radio module is designed and tested for the minimum times mentioned in the table. The
recommendations are there for those who want to do the very best possible startup and shutdown
sequences.

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, n, 8, 1. This is intended for service access of the
module, to have a known serial port setting in order to access the module settings.
The pin does not affect any permanent settings, nor does it change the mode of the module.
Releasing/ driving the pin high will return serial port 1 into the configured state.
When service pin is used the SL Commands are forced to be ON although they are OFF in
settings.

CONSIDERATIONS
8.1
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. -115 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 < -125 dBm (-115dBm-10dB),
causes desensitization of the radio on that particular channel.
Example:
An interferer has a level of -100dBm on the frequency 421 MHz. The radio will show an
approximate sensitivity of -90dB (-100dBm+S/N requirement 10 dB) on 421 MHz.
Now consider that generic EMC requirements usually have pass/fail criteria of -57dBm (if
normalized to the surface of the device). So there is almost a 70dB 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.
Number one is to recognize this challenge and act upon it.
SATEL R&D can help in this by participating in design review of the host device, aiming to catch
problems early in the design phase.

8.2
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.
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.
The module fulfills the ESD values listed in the following table.

8.3
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.
