BASpi-Edge controllers utilize the powerful 1.2 GHz 64-bit CPU in the Raspberry Pi 3 with 1 GB of RAM memory for lightning fast operation, its Ethernet and Wi-Fi adapters for versatile network connectivity, USB ports for extended functionality, as well as its HDMI port for human-machine interface for touchscreen or display options. Our field-proven, resilient I/O and power circuit board installed on top hardens the Raspberry Pi and allows it to safely interface with standard building automation input/output control signals and industry standard power supplies. A resilient 8 GB pSLC micro SD card ensures reliable operation and sufficient storage space. 24 VAC/VDC power input and a compact DIN rail mounted enclosure make it convenient to install.
In modern buildings, communication pathways and utility spaces are routinely provided. Historic structures, on the other hand, were not designed for routing cables or many other utilities (such as plumbing) that are standard today. We appreciate the craftsmanship and solid construction of these buildings and there is a desire to retain these architectural details and finishes while installing or modernizing a Building Management System (BMS) to comply with today's comfort, energy, and performance needs.
The challenge is how to install a modern BMS, such as BACnet, in an older structure with minimal impact. Fortunately, many older buildings have antiquated BMS systems in-place, using twisted-pair wiring. These wires are still serviceable.
It is possible to upgrade these buildings to a modern BACnet BMS using BASpi-Edge.
By using and configuring the optional EIA-485 to USB dongle (sold separately), the BASpi-Edge can be discovered as an MS/TP server device. In addition as a BACnet Client, it can directly read and/or write BACnet MS/TP device points on the connected bus.
The existing twisted-pair wires become a BACnet MS/TP network, with all the commissioning and troubleshooting features of BACnet.
