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

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.
