Connected IO modems attach to their host devices through USB serial ports. Setup is a simple as loading a device driver onto your host devices.

Both Linux and Windows drivers are available as easy-to-install software packages.

In order to activate a Connected IO device you need to contact your Carrier B2B sales representative.

If you are not currently working with a B2B sales representative please contact Connected IO at 669-221-6100 or via email at

Connected IO devices require external antennas to operate properly. For applications with low bandwidth requirements, in areas with solid 4G coverage, one antenna (primary) is sufficient. For all other applications, two antennas (primary and secondary) are required.

Operating temperature range for Connected IO Products is -25 to +60 degrees Celsius.

Connected IO doesn’t do exchanges.

You can verify the firmware version of your router by going to the Status/Overview page in the web interface.

You can compare that to the latest version of Firmware on the Connected IO Website. If a newer version is available, download it, and then push it to your Connected IO device through the SYSTEM/FLASH FIRMWARE menu.

In the NETWORK/FIREWALL menu, setup your firewall parameters and rules.


Under Windows, Connected IO modems are configured using the Connection Manager application.

Under Linux and Android, Connected IO modems are configured using AT commands or scripts, automating AT command sequences.

To connect Connected IO devices to a 4G network, type the following

  • AT%CMATT=1    //attach to the eNodeB and register on the network
  • AT%DPDNACT=1    //enable the data-plane

To disconnect Connected IO devices from 4G network, type the following

  • AT%DPDNACT=0    //disable the data-plane

If AT%DPDNACT=1 command results an ERROR, it most likely indicates problems with the SIM card activation. Please call your Carrier account manager to fix activation issues.

Connected IO devices support IP pass-through mode by default. IP addresses are assigned to the host device rather than the Modem.

Unlike a router, which is a standalone device, a modem is a peripheral and depends upon a host. Connected IO Modems support Windows and Linux hosts. Each needs a driver to know how to communicate with the modem.

Setting up a modem consists of three simple steps. First, install the proper driver on your host computer. Then connect the modem and power it up. Lastly, activate the modem and tell it where to 'communicate'.

To install the proper driver, go to the Connected IO Support Page and download the right drivers from the MODEM section of the page.

To connect, use the USB or Serial cable, as desired, and plug in the modem until the Power LED illuminates.

To configure the driver, download the User Guide from the MODEM section of the support page.


With dynamic IP addresses, incoming connections into the host system behind your devices are blocked.


With static IP addresses, inbound connections into the host system behind Machine Connect are allowed. Any application that requires remote access to the host device needs to use Static IP addresses.


Connected IO Modems are certified for Verizon Private Network connectivity.

The Modems can auto-connect to the Carrier network by simply executing this AT command from the Connection Manager Console.


After entering this command, it is necessary to enter this AT command to save the settings in the device


Auto-connect will work in all platforms including Linux.

For LT1000 and LT1002, use this command
