Page 8: Introduction
Introduction Strato Pi Base 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. Strato Pi Base 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. -
Page 9: Features
Features Strato Pi Base board and server: ✓ 9-28Vdc power supply, with surge and reverse polarity protection, and 1.1A resettable fuse ✓ up to 3.1A max current to the 5V Raspberry Pi power supply input pins (at 24Vdc) ✓ real time clock with replaceable CR1025 Lithium / Manganese Dioxide back-up battery ✓... -
Page 10: Usage And Connections
Usage and connections STRATO PI BASE CONNECTION DIAGRAM 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. -
Page 11: Strato Pi Base Server
Strato Pi Base server The Strato Pi Base server comes pre-assembled with a Raspberry Pi 3 Model B or 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). - Page 12 NOTICE Before opening the Strato Pi Base case, disconnect all power sources and any connection to external devices, including USB cables. Use a non-conductive pin or small tool to help extract the battery from its holder. Insert the new battery with a gentle push. You don't need tools to insert the battery. The battery is held into place by a spring contact.

Page 17: Disabling Bluetooth, Wifi And The Serial Console
Disabling Bluetooth, WiFi and the serial console On Raspberry Pi 3, the main UART is used for Bluetooth, and the TX/RX pins on the GPIO connector are controlled by a limited function Mini UART. To route the main UART to the RX/TX pins that are connected to the Strato Pi serial ports you should disable Bluetooth. -
Page 18: Using Strato Pi Base
Using Strato Pi Base Real Time Clock Strato Pi Base has a hardware real time clock with a dedicated long-life non-rechargeable back-up battery. Once the RTC modules and configuration files are properly installed, you will simply use the date and time commands to control the hardware clock. Serial port Strato Pi Base uses the Raspberry Pi standard UART TX/RX pins on the GPIO connector to implement a standard serial port with support for both RS-232 and RS-485. -
Page 19: Buzzer
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. -
Page 20: Hardware Watchdog
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 is normally disabled. -
