Hardware Installation

Strato Pi Base board

The Strato Pi Base board is supplied with all connectors pre-installed. No soldering is required. You should connect Strato Pi to Raspberry Pi through the GPIO connector. Use appropriate turrets/spacers to firmly bolt the two boards together, ensuring that no conductive part of one board touches any part of the other board.
Be particularly careful to ensure there is enough clearance between the Ethernet and USB connectors and the bottom of Strato Pi’s circuit board.
The GPIO connector of the Strato Pi Base board must be perfectly aligned to the Raspberry Pi's GPIO pins. Turning on the Raspberry Pi and/or the Strato Pi Base board with the GPIO not correctly connected will damage both the Raspberry Pi and Strato Pi Base.

Strato Pi Base server

The Strato Pi Base server comes pre-assembled with a Raspberry Pi 3 Model B+ or Raspberry Pi 4 Model B board, in a plastic standard DIN-rail case.
There is no need to open the case, unless a change in the RS-485 termination resistors is required (see below).
The Micro SD card (not provided) can be inserted through a small opening on the side of the case. Use a small pen or paper clip to gently push the card in its slot.

Replacing the RTC backup battery

Strato Pi Base has a hardware real time clock with a dedicated long-life non-rechargeable back-up battery.
Strato Pi Base is shipped with a CR1025 Lithium / Manganese Dioxide (Li/MnO2) battery installed.
The battery is only used to power the RTC chip when the main power is not available (when the Raspberry Pi is off). Depending on operating conditions it should last up to two years if the Strato Pi board is not powered, more if the Strato Pi Base receives external power.
Improper handling of lithium batteries can result in an explosion of the batteries and/or release of harmful substances.

THE STRATO PI BASE CIRCUIT BOARD

Power supply

Strato Pi Base can be powered with DC voltage only:
✓
DC: nominal voltage range 9.0V to 28.0V.
Respect the correct polarity shown in the schematic diagram (+ -). The power supply circuit implements reverse polarity protection using an auto resetting fuse and surge protection up to ±1000V/2ohms 1.2/50μs.
A blue on-board LED, also visible through the front panel of the DIN-rail case, is lit when power supply is available.
When a Strato Pi Base board is used, never connect the Raspberry Pi micro-USB power plug.
The Strato Pi Base power supply stage is optimised to deliver up to 4A at 5V to the Raspberry Pi. Because Strato Pi has a 2.2A resettable fuse (polyfuse) on the power supply line, the maximum current that its regulator can deliver is also limited by this fuse, and depends on the input voltage. The following table lists the typical measured output current of the power supply stage at different input voltages and the corresponding input current.

Strato Pi Base User Guide
Software installation and configuration
All features of Strato Pi Base are controlled via dedicated GPIO, the I2C bus and a soft serial RX/TX interface to the embedded micro-controller and can be used with most operating systems and programming languages.
The following software installation notes are based on the Raspbian operating system.

Installing the Strato Pi utility on Raspbian

The Strato Pi utility is a simple command-line script to control Strato Pi’s buzzer and watchdog functions.
Run the following commands to download and install the Strato Pi utility:
$ cd /usr/local/bin $ sudo wget http://sferalabs.cc/files/strato/strato $ sudo chmod 755 strato
You can run the Strato Pi utility without arguments to print its options:
$ strato Usage: strato beep on|off|length_millis|length_millis pause_millis repeats strato watchdog enable|disable|heartbeat|timeout strato shutdown strato battery
All commands should be run as superuser, so always use sudo to run strato.

Installing the Strato Pi kernel module

The Strato Pi kernel module can be used to easily access all of Strato Pi CM Duo control features via a sysfs file system.
Run the following commands to download and install the Strato Pi kernel module (see https://github.com/sfera-labs/strato-pi-kernel-module for detailed installation instructions):
$ sudo apt-get install git-core $ git clone --recursive https://github.com/sfera-labs/strato-pi-kernel­module.git $ sudo apt-get install raspberrypi-kernel-headers $ cd strato-pi-kernel-module $ make $ sudo make install
To have the module automatically loaded at boot add stratopi in /etc/modules:
$ sudo sh -c "echo 'stratopi' >> /etc/modules"
Optionally, to be able to use the /sys/ files not as super user, create a new group "stratopi" and set it as the module owner group by adding an udev rule:
$ sudo groupadd stratopi $ sudo cp 99-stratopi.rules /etc/udev/rules.d/
Then add your users to the group, e.g., for user "pi", and reboot:
$ sudo usermod -a -G stratopi pi
16
Strato Pi Base User Guide
$ sudo reboot

Installing the Real Time Clock software

The RTC is based on the Microchip MCP79410 module and is connected to the Raspberry Pi via its I2C serial bus.
Before downloading the installation utility, you should enable I2C and install the “i2c-tools” package.
To enabl e I2C, run the “raspi-config” configuration utility:
$ sudo raspi-config
Then go to “Advanced Options”, “I2C” and select “yes” to enable the I2C interface, then reboot your Raspberry Pi.
To install the “i2c-tools” package:
$ sudo apt-get update $ sudo apt-get install i2c-tools
With these prerequisite installs completed, you should download and run Strato Pi’s installation script:
$ cd $ wget http://sferalabs.cc/files/strato/rtc-install $ chmod 755 rtc-install $ sudo ./rtc-install
If the script completes with no errors, delete the installation script and reboot:
$ rm rtc-install $ sudo reboot

Testing the Real Time Clock

Assuming you are connected to the Internet and your Pi was able to reach a public NTP (Network Time Protocol) server, you should see the current date and time using the “date” command:
$ date Thu Dec 10 18:02:32 CET 2015
Also check the date and time stored in the hardware clock:
$ sudo hwclock -r Thu 10 Dec 2015 06:03:01 PM CET -0.546570 seconds
If the returned date and time is not correct, or “hwclock” returns an error, use the “-w” option to set the hardware clock to the current time:
$ sudo hwclock -w
Then recheck the time stored in the hardware clock to ensure it matches. Linux may have failed to automatically update the hardware clock after the last reboot if its internal registers contained invalid values.
17
Strato Pi Base User Guide
If the RTC still doesn’t work, you should check if the Pi sees the RTC chip on the I2C bus. Run these two commands:
$ sudo modprobe -r rtc_ds1307 $ sudo i2cdetect 1 WARNING! This program can confuse your I2C bus, cause data loss and worse! I will probe file /dev/i2c-1. I will probe address range 0x03-0x77. Continue? [Y/n] 0 1 2 3 4 5 6 7 8 9 a b c d e f 00: -- -- -- -- -- -- -- -- -- -- -- -- -- 10: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 20: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 30: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 40: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 50: -- -- -- -- -- -- -- 57 -- -- -- -- -- -- -- -- 60: 60 -- -- -- -- -- -- -- -- -- -- -- -- -- -- 6f 70: -- -- -- -- -- -- -- —
You should see “6f” in the address list. This is the address of the RTC.
If the RTC address is detected, double check your software installation for issues at the Linux modules level.
Run the “lsmod” command to list the loaded modules and check that “i2c_dev” and “i2c_bcm2708” are both listed.
If the RTC address is not detected, the cause could be a hardware problem, on the Strato board or the Raspberry Pi. If you have another Pi or Strato board, try swapping them to isolate the faulty board.
Configuring the serial port
On Raspberry Pi 3 and 4, the main UART (ttyAMA0) is used by default for Bluetooth, and the TX/RX pins on the GPIO connector are controlled by a limited function Mini UART (ttyS0).
To route the main UART to the RX/TX pins that are connected to the Strato Pi serial ports you could disable Bluetooth. Edit /boot/config.txt and add these lines at the end of the file:
# Disable Bluetooth dtoverlay=pi3-disable-bt
You may also run the following command to disable the Bluetooth HCI UART driver:
sudo systemctl disable hciuart
Alternatively, you may use the pi3-miniuart-bt overlay to switch Bluetooth to use the mini UART (ttyS0), and restore ttyAMA0 to GPIOs 14 and 15. Refer to the Raspberry Pi UARTs documentation page for additional information.

RS-485 JUMPERS POSITION

Buzzer

Strato Pi Base has an on-board buzzer that can be controlled using GPIO20. Simply set GPIO20 to high to emit a continuous sound, and back to low to stop. The buzzer is not intended to emit sound indefinitely and could be damaged doing so.
The Strato Pi utility has several commands to control the buzzer.
Buzzer on continuously:
$ sudo strato beep on
Buzzer off:
$ sudo strato beep off
Buzzer on for 500 milliseconds:
$ sudo strato beep 500
Buzzer on for 500 milliseconds, followed by 100 milliseconds pause, repeated three times:
$ sudo strato beep 500 100 3

Hardware watchdog

Strato Pi Base implements a dedicated hardware watchdog circuit that can be used to perform a full power cycle of the Raspberry Pi.
Being controlled by Raspberry Pi’s GPIO pins, it is extremely easy to control watchdog operation using simple custom scripts in your application.
The watchdog default behavior is described below, but all timing parameters and control logic can be modified as described in the "Strato Pi Logic Controller Advanced Configuration Guide" document.
The watchdog is normally disabled. To enable it, set GPIO6 pin to high. While GPIO6 is high, the Strato Pi controller will watch for state changes of the GPIO5 heartbeat pin. You should ensure that GPIO5 flips its state between high and low faster than every 60 seconds.
If the Strato Pi Base controller doesn’t see GPIO5 changing state for more than 60 seconds, it will initiate a shutdown procedure, rising the GPIO12 timeout pin to high, to signal that a watchdog timeout has occurred.
If possible, you should immediately initiate a software shutdown on Raspberry Pi, and set the GPIO16 shutdown pin to high. When GPIO16 is set to high or 60 seconds after the timeout, Strato Pi will wait 60 seconds more, then power cycle the Raspberry Pi.
Note that Strato Pi Base will power cycle the Raspberry Pi even if GPIO16 is not set high. In this case the power cycles occurs 120 seconds after the heartbeat timeout.
The Strato Pi utility can be used to control the watchdog from your own application.
22
Strato Pi Base User Guide
Enable the watchdog:
$ sudo strato watchdog enable
Disable the watchdog:
$ sudo strato watchdog disable
Send the heartbeat:
$ sudo strato watchdog heartbeat
Print “1” if the watchdog timeout is expired, “0” if not:
$ sudo strato watchdog timeout; echo $?

Power cycle

You can start a delayed power cycle by rising Raspberry Pi’s GPIO16 pin.
When GPIO16 is set to high, Strato Pi Base will wait 60 seconds and then power off the Pi board for 5 seconds.
The power cycle also affects the VSOUT auxiliary power supply output.
To initiate a delayed power off cycle:
$ sudo strato shutdown
Advanced configuration
The Strato Pi Base logic controller can be configured from the Raspberry Pi to change the default behavior and timing of the hardware watchdog. The RX/TX switching mode (TX­Enable control) of the RS-485 serial port is also configurable.
These configuration parameters can be accessed using the Strato Pi kernel module or implementing the underlying ASCII-based serial protocol described in the "Strato Pi Logic Controller Advanced Configuration Guide" document.

Thermal considerations for Strato Pi Base server

The Raspberry Pi draws power and generates heat proportionally to CPU and GPU load.
The Strato Pi main regulator also generates heat proportionally to the total amount of current that it has to supply to the Raspberry and, if present, external devices.
The thermal behaviour of Strato Pi Base server is dynamic and affected by operating conditions and the external environment temperature.
The Raspberry Pi CPU has the ability to throttle down its clock speed once a certain core temperature is reached. This prevents CPU overheating, also limiting the temperature inside the enclosure, when the CPU load is high for a significant amount of time.
The following charts show the thermal behaviour of Strato Pi Base server in different conditions, in a typical installation with the device under test installed in a standard, not ventilated DIN cabinet:
