If you intend to integrate with MachineMetrics by connecting your machines through a cellular network, please review this article in detail before attempting your integration. If you plan to integrate your machines using a cradle point or via a wired or wireless network, please review the articles available for those specific network options instead. You can find all of our available network articles here.
This article provides detailed instructions for a successful connection to MachineMetrics through a cellular network, including an overview of the required hardware, as well as the necessary prep work for your network and machines.
Topics covered in this article:
- Cellular Viability
- Preparing Your Machines
- MachineMetrics Edge Hardware

For a successful cellular connection, the cellular USB modems provided by MachineMetrics will need to connect to an existing AT&T signal. You will need a cellular signal strength greater than 90 dBm available at each machine you intend to connect. If you aren't sure about your current cellular signal, please reference our knowledge base on how to test the strength of your cellular signal.
If you have no cellular signal available near your machines, then a cellular connection is not an option. If you do have a cellular signal, but it is below the required 90 dBm specification, you can purchase a signal booster/repeater, and place it within 100ft of the machines you wish to integrate and retest the signal strength.
Preparing Your Machines
Someone within your organization familiar with your cellular signal should make sure you have a strong AT&T signal near each machine you plant to integrate. Cellular connected machines are completely separated from your network through a secure M2M network on MachineMetrics' custom API. Billing for this service is monthly at approximately $15 per month, per machine.
If your machine does not have an available throughput or sealed passthrough leading to and from the electrical cabinet, you will need to drill a 3/4 inch hole in order to accommodate the MachineMetrics Cellular USB modem. The cellular modem will be mounted to the outside of your machine and connected to a MachineMetrics Cellular-enabled Edge Device via a USB extension cable.
Note: If you will need access to your machine's control on your internal network, you will want to consider the wired integration option instead.
MachineMetrics Edge Hardware
Upon finalizing your contract with MachineMetrics, you should have been shipped a Cellular-enabled Edge Device for each machine you intend to connect. Please ensure you have the proper number of Edge Devices to complete your integration. If you appear to be missing any Edge Devices, please notify your customer success manager.
A MachineMetrics Edge Device is required for each machine when pursuing a cellular network connection. It is powered by 24V from the machine or a nearby 110V outlet. The Edge requires a cellular network with strong signals near your machines.
Note: On the bottom of the Edge you will find its serial number. It’s important to write down or take a picture of this number; will need this number once it is time to register and configure your Edge Device.
MachineMetrics Edge Software
This device hosts our proprietary software which allows for machine data collection, buffering, and cloud migration. The MachineMetrics Edge also runs an IoT device management service called Balena. This allows MachineMetrics to remotely keep Edge Devices up to date and monitor their status. An outbound-only VPN is configured from the Edge to Balena that MachineMetrics manages in order to troubleshoot issues and send updates automatically. The operating system is a lightweight version of Linux.
Note: Mitsubishi M70 (other than M700 that operate Citizen machines) and Heidenhain TNC640 controls require installation on a separate Windows PC that has access to the Machine’s control.
Cellular USB Modem
You should receive a cellular USB modem for each Edge Device. Please ensure you have the proper number of USB modems to complete your integration. If you appear to be missing any USB modems, please notify your customer success manager.
Once you've unpacked your cellular modem, you will see a 20 digit ICCID number taped to it; save this number and make certain it remains associated with the serial number corresponding to the Edge Device to which the USB modem will be connected. The ICCID number is also printed directly on the modems' SIM card.
Each SIM card ICCID is unique and has been associated exclusively with the cellular modem with which it came. If it is inserted into any other device, it will not function.
Once you have checked on your cellular viability, prepared your machines, and confirmed that you have received all of the necessary hardware, the next step is to install your Cellular Edge Device directly into your machine's electrical cabinet.
