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: SoftwareCellularSoftware 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.
