Enabling billions of unconnected
devices to connect to the internet
and each other for intelligent
decision making to help businesses
achieve its most important
business outcomes

Use Case : IR Temperature Sensor
Customer orders
drink through
Barita app
Barista prepares
drink as usual
Drink placed on
a special IoE
enabled surface
Sensors measure
presence and
temperature
Notifications
Enabled
Enables businesses to achieve higher productivity & provide superior customer
experience

Use Case : Connecting Legacy Machines
Legacy machines need
technician to manually
collect data, inspect the
machine & determine
problem
Connect serial ports of
legacy machines to
factory network securely
using Talem along with
other sensors
Remotely connect,
command & collect
information from older
legacy machines
Enables businesses to monitor, collect valuable data and do preventive
maintenance lowering risk

Why?
• Why wires?
• Reuse existing legacy networks
• Leverage wired network functionality: PoE, Security, Speed
• Why a central switch?
• The switch is the master controller
• Ease of software deployments: 10 nodes vs 1500 nodes
• IoT devices are just network nodes

EIoT Development Kit Benefits
Power over
Ethernet
• Ideal for energy hungry
sensors
• Eliminate battery
replacements & single
cable for power & data
Plug n Play
connectivity
• No coding required on
the endpoint
• Application runs in the
cloud versus the
endpoint
Secure Platform
• Handle sensitive data
• Lower risk of dropped
packets
Management
• Remotely configure
settings
• Software defined
policies
Lightweight
• Low cost adapter
• USB devices are cheap
and plentiful
IoT Platform Enabled for the Enterprise

• Connect to one of the switches via Ethernet
• The switch will give you a 10.0.#.# address, depending upon which switch you are connected
• To connect to a sensor via the Adapter, you target the
switch and request it to read the data from the attached
• You _can_ share the Adapters, but it is not advised
Getting Connected

13. 13© 2015 Cisco and/or its affiliates. All rights reserved. Cisco Confidential
• You will need to use Python 2.7+ (python2.7)
File "/Users/mikemaas/Dropbox/Code/EIoT/eiot-example-python/get_info.py", line 3, in <module>
import usb
ImportError: No module named 'usb'
• The Cisco PyUSB module is required
• You can download it from the EIoT portal
• https://developer.cisco.com/site/eiot
• PYTHONPATH needs to point to the Cisco PyUSB module
