Instrumentation Newsletter - September 2019_



The Internet of Things (IoT) has paved the way for millions of connected wireless devices to route information and get things done. The enabling technologies of the IoT allow connected devices to gather and send data, handle remote or risky tasks without human intervention, monitor assets to avoid unnecessary service calls, and gather critical information from widely dispersed and demanding environments.

To effectively manage a complex IoT deployment requires an IoT device management application that not only lets you visualize the activity of complex networks in a simplified form, but also provides these important capabilities:

Management: Manage large numbers of devices efficiently
Monitoring: Monitor IoT deployments and ensure all devices are operating as expected
Security: Continually scan the deployment for security issues and repair them.

These capabilities must be seamless across devices and third party applications from the cloud to the edge of the network. In this white paper we will talk about IoT management paradigms, and how a sophisticated remote management application, paired with a strong security framework, can help manage your connected world more efficiently and securely. We will also introduce the capabilities of Digi Remote Manager® (DRM), the Digi TrustFence® security framework, and the Digi Foundations hardware, management and support package.


Challenges in the Management of Connected Devices
The challenges involved in managing IoT devices are many and varied:

• Devices may be difficult to reach, such as those located at the top of a pole, on a remote highway, or out at sea. Once these devices are installed, it is inconvenient and expensive to go back and check on them or service them.
• Devices may be in motion - for example, if they are installed on a delivery vehicle or city bus. You need to be able to communicate with these devices while they are in transit, wherever the vehicle may be located.
• Your device network may be geographically diverse and deployed in large numbers. You need to be able to communicate with and manage devices on a large scale.

When identifying strategies for managing and servicing devices in your IoT deployment, it may help to think about them as being on another planet. Regardless of their locations, you will need to be able to monitor those devices, communicate with them, send commands to them, and update firmware and security patches across your entire network.

Digital I/O Carrier Board for Raspberry Pi

The Digital I/O Carrier Board for Raspberry Pi® lets you switch industrial-level electrical loads with your Raspberry Pi. Control real-world devices like industrial motors, pumps, and sensors by using your Pi to read and write to up to 16 digital I/O modules.

Great for prototyping IIoT solutions, proofs of concept, and projects where an industrially hardened controller isn't required. (Raspberry Pi, I/O modules, mounting rack, and power supply all sold separately.)


Digi XBee3® Series programmable modules take smart to a whole new level. Building on industry-leading embedded technology, the Digi XBee3 Series offers design freedom with easy-to-add functionality and flexible wireless connectivity.

You can do IIOT wirelessly using Zigbee, Wifi, Cellular and direct RF

Raspberry Pi interfacing to Industrial and Wireless products

There is a lot of buzz surrounding the Raspberry Pi platform. Due to its eye-popping capabilities and low price, engineers are investigating more ways to use it in their designs.
Raspberry Pi is the 3rd best-selling general-purpose computer platform, trailing only the Microsoft® Windows® PC and Apple® Macintosh®, with over 12.5 million sold as of 2017.

The secrets to its success are in price, performance, and flexibility. The Raspberry Pi 3 Model B+ offers a 64-bit quad-core ARM processor, gigabit ethernet, wireless, Bluetooth, 4 USB ports, micro SD slot, and HDMI output.
While originally created for the education market to teach computer science to students across the globe, it has rapidly expanded beyond the intended market into the hobbyist/maker market and increasingly into industrial/commercial markets.

The power and capabilities of the Raspberry Pi is starting to be leveraged widely across industry. The success of the Raspberry Pi in processor intensive, professional engineering applications is why it is now being considered as an OEM option for industrial designs.

Low cost IIOT (for industrial not Commercial level). The OPTO 22 IO can absorb nasty industrial level noise and electrical abuse and still work. Like electric motors starting, VSDs and other noisy items. etc.
