Safety instructions
General safety instructions
Protect the unit against moisture, dirt and any kind of damage during transport, storage
and operation. Do not operate the unit outside the specified technical data.
Never open the housing. If not otherwise specified, install in closed housing (e.g.
distribution cabinet). Earth the unit at the terminals provided, if existing, for this purpose.
Do not obstruct cooling of the unit. Keep out of the reach of children.
Life threatening voltages are present within and around an open control cabinet.
When installing this product in a control cabinet or any other areas where dangerous
voltages are present, always switch off the power supply to the cabinet or equipment.
Risk of fire if not installed and operated properly.
Follow all applicable electrical safety standards, guidelines, specifications and regulations
for installation, wiring and operations of this product.
The Raspberry Pi board could generate a substantial amount of heat when the software
forces the CPU and/or GPU to operate at high load levels. Ensure that the product is
properly installed and ventilated to prevent overheat.
The connection of expansion devices to this product may damage the product and other
connected systems, and may violate safety rules and regulations regarding radio
interference and electromagnetic compatibility.
Use only appropriate tools when installing this product. Using excessive force with tools
may damage the product, alter its characteristics or degrade its safety.
Battery
This product uses a small lithium non-rechargeable battery to power its internal real time
clock (RTC).

Strato Pi CAN User Guide
Improper handling of lithium batteries can result in an explosion of the batteries and/or
release of harmful substances.
Worn-out or defective batteries can compromise the function of this product.
Replace the RTC lithium battery before it is completely discharged. The lithium battery
must be replaced only with an identical battery. See the "Replacing the RTC backup
battery" section for instructions.
Do not throw lithium batteries into fire, do not solder on the cell body, do not recharge, do
not open, do not short-circuit, do not reverse polarity, do not heat above 100°C and protect
from direct sunlight, moisture and condensation.
Dispose of used batteries according to local regulations and the battery manufacturer's
instructions.

Introduction
Strato Pi CAN enhances the Raspberry Pi Model B version 2 and 3 computers with several
hardware features to make it suitable for use in professional applications where reliability
and service continuity are key requirements.
It is available as a bare board or fully assembled unit including a Raspberry Pi 3 Model B
or B+ in a standard DIN-rail case.
The information contained in this manual covers all versions, except where explicitly stated
otherwise. The bare board is called “Strato Pi CAN board”, while the assembled unit is
“Strato Pi CAN server”.

Features
Strato Pi CAN board:
✓9-65Vdc power supply, with surge and reverse polarity protection, and 1.3A resettable
fuse
✓Controller Area Network (CAN) V2.0B interface, support speeds up to 1 Mb/s, with
opto-isolator and electrostatic discharge protection
✓standard RS-485 interface to the Raspberry Pi serial line, with opto-isolator and
1
electrostatic discharge protection
✓up to 2.5A max current to the 5V Raspberry Pi power supply input pins (at 24Vdc)
✓real time clock with on-board lithium back-up battery
✓one relay with change-over (CO), Single Pole Double Throw (SPDT) terminals
✓on-board buzzer, connected to an I/O pin of the Raspberry Pi board, for acoustic
feedback
✓hardware watchdog implemented in the Strato Pi board, fully independent from the
Raspberry Pi, controlled via the I/O pins of the Raspberry Pi board
✓on-board LEDs for power supply, RS-485 and CAN bus activity
✓power supply and serial connections on a screw terminal block
Strato Pi CAN server only:
✓pre-assembled and tested Raspberry Pi 3 Model B or B+ with Strato Pi CAN board in a
standard 4 modules DIN rail case
✓side access to HDMI and 3.5mm jack for audio and composite video
✓access to all USB ports and Ethernet port (opposite to the power and serial terminal
block).
The RS-485 and CAN interfaces are independently opto-isolated, but are powered by a single
1
galvanically isolated DC-DC converter. This means that the RS-485 lines are not galvanically
isolated from the CAN lines.

Usage and connections
STRATO PI CAN CONNECTION DIAGRAM
Hardware Installation
Strato Pi CAN board
The Strato Pi CAN board is supplied with all connectors pre-installed. No soldering is
required. You should connect Strato Pi to Raspberry Pi aligning 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 CAN circuit board.
The GPIO connector of the Strato Pi CAN board must be perfectly aligned to the
Raspberry Pi's GPIO pins. Turning on the Raspberry Pi and/or the Strato Pi CAN board
with the GPIO not correctly connected will damage both the Raspberry Pi and Strato Pi
CAN board.
