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). Will turn the module into a state where it will hold parts of the radio on, wakeup will take approx. 30 ms
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%. Dedicated mode to configuring radio module while radio is in idle mode and cannot transmit or receive.

5.1 Safe mode
When a fault has been detected by the Firmware, the module is set to Safe mode. In this mode the module sends an Error message to Mini PCIe interfaces to and reboots the device after five (5) seconds. 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 1.7.4 or newer is compatible with SATEL- TR49 SnapOn radio transceiver module.
5.2 Restart
After startup the module can be restarted by issuing an SL command, upon which the module will shut down all circuitry, and Reboot the CPU (see SL command list).

6. CONFIGURATION
The configuration of settings can be changed easily – the next chapters describe the details:
SATEL SW tools Easy-to-use SATEL software tools suit most cases. Please see additional information in next chapters. SL commands A terminal device can command or configure the radio modem by using special commands. SL commands are applied especially in cases where radio modems are to be integrated seamlessly inside a system behind the integrator’s own user interface.
The parameters changed to a device on frequency hopping 900MHz band are taken into use after either radio reboot command, electrically restarting the device or exiting from the command mode (see SL Command Mode).
6.1 SATEL NETCO DEVICE software
SATEL NETCO DEVICE is a software for configuring and reprogramming a SATEL device. The configuration parameters can be read and written from/to the locally connected, powered device. The device configuration can be also created/saved/explored from/to a file without device connection.
The most common use case for which the SATEL NETCO DEVICE is optimized for is editing existing parameters in a SATEL radio product using local connection, such as serial interface.
Please see additional information from SATEL WEB pages at: https://www.satel.com/products/software/ The software is available from SATEL WEB pages at: https://www.satel.com/support-andservices/downloads/
6.2 SATEL Configuration Manager software
SATEL Configuration Manager is a software for configuring and reprogramming a SATEL device. The parameters can be read and written from/to the connected, powered device. The program file can be saved into a separate file to be used to other devices.
The most common use case for which the SATEL Configuration Manager is optimized for is editing existing parameters in a SATEL radio product using locally connected product over a serial interface. Minimum requirements: COM port with baud rate min. 9600 bps (alternatively with industrial level USB- RS-232 converter).

6.3 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.
6.3.1 SL Commands
The controlling terminal device can change the configuration settings of a radio. This is accomplished with the help of SL commands, which can be used during data transfer. SL commands can be used to change e.g. the frequency or addresses. It is also possible to interrogate a radio modem in order to gain information concerning current settings that are in use. SL command -setting must be enabled before they can be used.
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 (=ASCII character no. 13, Carriage Return, 0x0d) or ( = 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. SL command response time depends of the used command. Typical response time is ~100ms and upwards. Recommended safe timeout for SL command response is 500ms.
it is possible to use SL commands in Port 2 (TD2 signal in GPIO3 (Pin13) and RD2 signal in GPIO1 (Pin11)) when Port2 Function has been configured as Diagnostics. SL commands can be used even in parallel with Port1 ­ in that case the response appears in the same port where the SL command came from.
Port2 is configured via SL commands or SW tools (SATEL NETCO DEVICE or SATEL Configuration Manager) by selecting the Port2 Function:
· OFF (=Port 2 not in use) · Diagnostics (=SL commands ON in this case)
CR/LF characters are added to end the response messages (unless they are already present) in order to make parsing easier. Settings can be toggled, SL Commands ON/OFF, CR/LF ON/OFF.
24

SATEL-TR49 SnapOn User guide, version 2.1
See Appendix B and C for SL commands. To get information of the latest and/or special SL commands please contact SATEL or local SATEL distributor: https://www.satel.com/where-tobuy/.
6.4 SL Command Mode
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 by using SL commands or toggling the “SL Command mode” parameter via SATEL SW tools, SATEL NETCO DEVICE or SATEL Configuration Manager (maintenance access level required).
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 by using the below described procedure. Regardless of original SL command ­setting state, changing the setting state with this procedure will affect the reception process of the radio module.
Radio can be set to Command Mode separately with “+++” command, regardless of the set SL command mode (ON/OFF). Command mode enables forcibly the SL command mode and disables the radio interface functions (Tx/Rx). By exiting from the Command Mode, user defined SL command parameter mode is restored, as well as radio interface functions.
To enable the Command mode: · Send three “+” characters via serial port so that there is at least three bytes delay (according to Pause Length -setting) between each character. The response is “OK”, when successfully set. <+><at least three bytes pause><+><at least three bytes pause><+>
To disable the Command mode: · Send three “-” characters via serial port so that there is at least three bytes delay (according to Pause Length -setting) between each character. The response is “OK”, when successfully set. <-><at least three bytes pause><-><at least three bytes pause><->
*Pause Length -setting
Note! The “+ + +” and “- – -” procedures are not recommended to be used when radio is transmitting or receiving data (i.e. the application data occupies the TD or RD lines of the radio). Note2! 900 MHz frequency band parameters set via SL commands require device restart for the new parameters to be taken into use. The device reset is performed during exiting the command mode (—).

9. CONSIDERATIONS
9.1 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 Mini PCIe interface (power, control and data lines).
Because the module is shielded and the Mini PCIe 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 have an approximate sensitivity of -90 dBm (-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.
28

SATEL-TR49 SnapOn User guide, version 2.1
9.2 Electrostatic discharge
As the module is intended to be embedded in a host device, 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.
9.3 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 cannot 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 cannot 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 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 perform a module restart using the W-Disable pin or by issuing a restart command, or a cold boot by toggling +3,3Vaux low and high again.
29

SATEL-TR49 SnapOn User guide, version 2.1
9.4 Additional improvements for more reliable radio link
In case where one or more performance value is not met and the environment is challenging, the following mechanism can be used for improving the transmission reliability: · Forward Error Correction, FEC, is recommended to use in challenging environment like urban areas. · Directive antennas. · Before building the radio link(s) it is highly recommended that the radio environment is measured to find out whether the radio environment is clean enough by using e.g. a spectrum analyzer or radio router’s RSSI value. · Co- operation with the local authority to find out the optimum free radio channel. · If the channel is disturbed an external out-of-band filter can be used for improving the filter capacity. · If at the adjacent channel is TDMA, Time Domain Multiple Access, transmitter can use for receiving a time slot which is not in synchronization with the TDMA radio transmission. · In Europe it is not recommended to use channels which are located near by the TETRA or television frequencies.
