Introduction
RUT2CLOUD evaluation kit has been designed by Rutronik for IoT cloud connectivity
projects development and promotion. Low power Renesas Synergy S3A7 MCU and Li-ION
battery charger enables the board to be used for portable and battery powered applications.
The power source for the Telit modem is switched between USB and battery automatically
by the circuit on board. The MCU, modem, GNSS module and sensors might be evaluated
independently.

Demo Firmware
RUT2CLOUD comes with already preprogramed demo firmware for Telit modem
control and sensors monitor via Micro USB port.
By default GNSS module is bundled together with modem, thus it can be controlled
via xL865 modem.
Demo firmware acts like USB Bridge between USB and COM or IIC simultaneously.
Each time USB is connected to PC, two virtual COM devices are detected: one for xL865
modem and another for IIC sensors. In order to be able to operate the demo kit, following
software is needed:

Synergy USB CDC Driver.
Telit AT Controller.
Rutronik Sensor Monitor application.
Synergy USB CDC driver’s installation manual is provided by Renesas: Look for
Application note R11AN0303EU0100 “Installing Synergy Signed USB CDC Driver“.
Tellit AT Controller software and manuals are provided by the Telit Company. The
application may be downloaded after login here: https://www.telit.com/support-
training/download-zone/ (path: SoftwareCellularSoftware Tools).
Rutronik Sensors Monitor application for Windows OS may be find in github:
https://github.com/RutronikKaunas/rut2cloud_sensor_monitor
No installation is required.
Recommended steps for launch RUT2CLOUD with demo firmware:
1. Install Synergy CDC Driver and Renesas e2 Studio.
2. Attach RUT2CLOUD Micro USB port to PC and push the “Reset” button
shortly. Wait for device installation to finish.
3. Identify the USB Serial Devices installed on yours PC.
4. Launch the application (Tellit AT Controller or Rutronik Sensors Monitor).
Please use only one application at a time.
5. Select the appropriate serial port and continue to operate the application
selected.

USB Serial Devices could be identified by its ID as it shown in Fig. 4. MI_00 is for
modem and MI_02 is for IIC sensors.

Programming via Micro USB port
RUT2CLOUD Board could be programmed using “Renesas Flash Programmer” via
USB port.
The “Renesas Flash Programmer (Programming GUI)” and documentation is provided
by Renesas.
RUT2CLOUD Board has to be set to “USB Boot Mode” before using the application.
In order to do that, do the following steps:
1. Install the latest “Renesas Flash Programmer” (it comes with drivers).
2. Attach USB port to the PC.
3. Press and hold the “BOOT” button and while holding press the “RST”
button once.
4. Wait for the “Synergy USB Boot” device is detected and installation is
finished by yours machine.
5. Setup the firmware to connect to the “Synergy USB Boot” COM port,
select the Intel hex or Motorola s binary source file and proceed with programming.
Note: The “BOOT” button must be kept pressed before the programming
starts and during the programming!

Telit GNSS Bundle Solution
RUT2CLOUD demo kit’s hardware and firmware is configured to be in “Telit Bundle
Solution” configuration by default. Thus Telit GNSS module can be managed using AT
commands that are sent to Telit cellular module. In case the configuration has been lost, it
can be restored using AT commands sequence written below.

RUT2CLOUD User’s Manual
In order to have bundle configuration the cellular and GNSS modules are connected
via circuit breakers SB11, SB12, SB13, SB14. GNSS module may be evaluated separately if
all these circuit breakers are cut.
SIM Card’s Selection
RUT2CLOUD Modem has two SIM cards. One is Nano SIM and another is embedded
SIM. The analog switch ISL84467 is used to select between SIM cards. Embedded SIM is
always selected by default every time the system is powered up. In order to select Nano SIM
(or eSIM), AT commands sequence has to be executed as shown below.

External Antennas Cellular Antenna
An antenna must be connected to modem’s U.FL socket. The antenna requirements
are shown below:
GL865 V3.1 ANTENNA REQUIREMENTS
Frequency range
Depending by frequency band(s) provided by the
network operator, the customer shall use the most
suitable antenna for that/those band(s)
Bandwidth
70 MHz in GSM850, 80 MHz in GSM900, 170 MHz
in DCS & 140 MHz PCS band
Impedance
50Ω
Input power
> 2 W
VSWR absolute max
≤ 10:1 (limit to avoid permanent damage)
VSWR recommended
≤ 2:1 (limit to fulfill all regulatory requirements)
Molex cellular quad band antenna (Part No.: 146185-0100) is recommended for
RUT2CLOUD board.
GNSS Antenna
Since SL876Q5-A has internal antenna the GNSS external antenna is not necessary
unless user cuts the SB16 and solders the SB15 circuit breaker. U.FL external antenna
accepts GNSS signals in the range of 1561 MHz to 1606 MHz at a level between -125 dBm
and -151 dBm into 50 Ω impedance. Molex GPS and Wi-Fi Combo antenna might be used
(Part No.: 146186-0100).

Li-ion Battery Charger
Though the ISL9203A is capable to deliver 1.5A to the Li-ion battery, the current is
decreased to 444mA in order not to overload USB host. If RUT2CLOUD board is powered
from external 5V power source or more powerful USB host is used, the current may be
increased by changing the resistor R7 value. The charge current may by calculated using the
equation given below:
