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.
SATELLINE-M3-TR3 and –TR4 Integration Guide, Version 1.6 8 1.3 DTE connector The DTE connector is a 20-pin pass-through connector. This connector allows the pin to enter the connector from the bottom side and protrude thru the module PCB to the top side, allowing flexible mounting heights with various pin lengths.

SATELLINE-M3-TR3 and –TR4 Integration Guide, Version 1.6 12 3 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 and –TR4 Integration Guide, Version 1.6 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).
SATELLINE-M3-TR3 and –TR4 Integration Guide, Version 1.6 14 4 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 and –TR4 radio transceiver modules. 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 and –TR4 Integration Guide, Version 1.6 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: tmarg = 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 and –TR4 Integration Guide, Version 1.6 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 tRX slot, min = tmin - tmarg tRX slot, max = tmin + toverlap tTXtmintRX slott0tsleeptoverlaptmarg 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).
SATELLINE-M3-TR3 and –TR4 Integration Guide, Version 1.6 17 5 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. Table. Startup and shutdown sequence parameters. *) Recommendations: 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.

SATELLINE-M3-TR3 and –TR4 Integration Guide, Version 1.6 19 5.3 Stat pin The STAT pin indicates the status of the device. It can be used to drive a LED using a series resistor. STAT pin drive capability is 10mA (loads the VCC_IO). The STAT pin has the following behavior. 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 interval Module is sending data Over the Air Pin is toggled in 1s interval Module has the connection to Configuration Manager program. Pin is toggled in 500ms interval SL Command mode. Pin is toggled in 250ms interval Module has detected a fault, fault codes can be read via Configuration Manager program. Table. Modes of STAT pin. 5.4 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.

SATELLINE-M3-TR3 and –TR4 Integration Guide, Version 1.6 24 8 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.
SATELLINE-M3-TR3 and –TR4 Integration Guide, Version 1.6 25 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. Specification / Requirement Contact discharge Air discharge EN 61000-4-2 Antenna interface ±10kV <±15kV DTE interface ±8kV - JEDEC JESD22-A114D (Human Body Model, Test conditions: 1.5 kΩ, 100 pF) Module surface ±1kV n.a. Table. ESD ratings. Measured Acc. to EN 61000-4-2 specification. 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.
