Introduction
The Network Pro is one of the communications devices in the AoFrio IoT system. It provides real-time automated
data acquisition from AoFrio SCS controllers, Monitors and Clicks installed in your coolers in the field, adding a
cellular connectivity option to the existing portfolio of data acquisition solutions provided by AoFrio. Connectivity over
the cellular network eliminates the need for site visits to acquire data from the asset fleet, or update the firmware on
the Network Pro.
Communications
Network Pro is equipped with 2 different types of radio connectivity:
• Bluetooth - The device is fully compatible with the AoFrio IoT system and uses Bluetooth to acquire data from
up to 16 AoFrio IoT devices.
• Cellular connectivity - Network Pro is equipped with a global cellular module that provides connectivity
using LTE Cat M1 with 2G fallback. Cellular SIMs are installed at the time of manufacture and the data plan is
managed by AoFrio unless an alternative arrangement has been made.
Battery
The device has a rechargeable internal battery that is used for backup if the external power supply is removed. The
battery life is approximately 12 hours during which time the Network Pro will continue to operate fully as though still
connected to its external power supply.
Location Reporting
Wi-Fi positioning is used to help determine the location of the Network Pro, and therefore also the coolers that
are within Bluetooth range. WiFi is not used to transfer data i.e. Network Pro is not capable of establishing a WiFi
connection.
The port is a non-standard USB-C and is only intended to be used by AoFrio during manufacturing. Connecting anything
to this port may damage the product and void the product warranty.
DO NOT USE THE USB-C PORT

What’s in the box?
Planning where to install your Network Pro
Network Pro can be installed as a hub to connect up to 16 AoFrio IoT devices in the point-of-sale that are
within Bluetooth range. Make the following decisions:
1. Determine the quantity and location of AoFrio IoT devices within the point-of-sale
2. Download the Field App and verify the connection
3. Decide the mounting position in accordance with the requirements in this manual
4. Identify a suitable power source for the Network Pro (maximum of 2 meters from the mounting position)
5. Mount the Network Pro device using the appropriate mounting method for your field conditions or location
Mounting position
Install Network Pro as close as possible to the coolers being tracked,
ideally not more than 5 meters away. For best results, install with clear
line of sight between Network Pro and the devices being tracked (SCS or
Monitor for example).
With clear line of sight, connections of up to 10 meters away may
be possible.
The recommended mounting location is on top and slightly back from the
front of the cooler, where it is high up for best signal quality, but out of sight
of customers.
