Power & Connectivity
Power and connectivity are the inevitable obstacles to the deployment of gateway infrastructure, regardless of the physical space or the scale of the installation.
Having faced these obstacles countless times since 2004, in 2012 the reelyActive co-founders developed the reel:
The reel principle
Regardless of the physical space or the scale of the installation, the reel principle is as follows:
- locate the nearest viable source of power and connectivity
- pull a network cable from the source to the first reelceiver*
- pull a network cable from that reelceiver* to the next
- repeat as necessary
*A reel consists of one or more gateways called reelceivers.
The reel accepts input voltages from 5-45VDC facilitating direct connection to commonly available power sources such as:
- AC/DC transformers
- Vehicle batteries
The reel supports long-distance serial communication using RS-422 facilitating driverless connection to common devices such as:
- Industrial Serial-to-Ethernet/WiFi/Cellular hubs
- Embedded computers (ex: Pi)
- USB (via RS-422 converter)
The reel purpose
The reel was conceived to provide a simple, versatile and highly modular means to capture and relay, in real-time, all the ambient data in any physical space.
Our ambient data gateways are all based on the reel architecture, with even devices such as our Owl-in-One using a single reel module serial-connected to an off-the-shelf embedded computer.
