1. Introduction
The Connected IO EMU CAT1 Modem is designed for applications leveraging Low Category LTE
technology. These LTE CAT1 modules will deliver data rates of 10Mbps downlink and 5 Mbps uplink in
an optimized network like Verizon or AT&T. The EMU CAT1 Modem is a compact module offering LTE
connectivity with 3G fallback across numerous carrier independent networks depending on the end
customers’ requirements.
This document provides instructions and basic operational guidelines for a Systems Administrator in the
use and monitoring for the EMU CAT1 Modem family of products.

The EMU Modem requires a data plan that has been activated by a specific carrier. The activation will
require a valid ICCID and IMEI numbers listed on the device before the activation can be completed.
3.1. Device Driver and Software Documentation
To locate the current device drivers, software updates, and documentation for a particular device requires
a user to register his device with Connected IO. This can be accomplished at:
https://www.connectedio.com/pages/software
4. Modem Usage in Windows
The following Sections, 4, 5, and 6 are excerpts directly from Telit Wireless to help the user manage
the EMU Modems, EM1000T-XX-CAT1. For a more detailed explanation than what is provided here
the user will need to register with Telit Wireless, http://www.telit.com/download-zone/.
4.1 TMB Tool
Telit provides the TMB tool that furnishes a simple interface to activate/deactivate the NCM, (Network
Control Module), protocol in Windows environment. Please check our “Software” page at
www.connectedio.com to download the tool. Before running the tool
1
, verify if the:
•current port configuration is #PORTCFG=0 (default);
•mode is #USBCFG=0 (default); USB3 port is available.
The Fig. 1 shows how the Telit Mobile Broadband tool appears on the display.

5. System Configuration –Windows-
5.1. AT Command
To send AT commands, download and install the Telit AT Controller software (TATC). See section 3.1 on
where TATC is located. Follow the steps below to access the AT terminal: NOTE: TCM and TATC use
the same DM- Port so turning off TCM prior to using the TATC will be required.
1. Start Telit AT Controller software. (Usually the connection manager installer will create an
icon on the desktop. If not, type “Telit AT Controller” in your Windows search field to locate)
2. Verify which serial port the device should be communicating on in the Windows Device
Manager.

3. Click on the “Play” button it will connect the Telit AT Controller to the serial port so
communication can be established with the modem.
4. Click on “AT terminal” button.

6. You can use the AT command to check the LTE status.
a. The AT command format is “AT+ Command”for example: AT+CSQ. Enter the AT
command and click “Execute”. Figure 1
7. AT command responses, will be displayed in the terminal window on the right side of the
Telit AT Controller software. Figure 1.

5.2. APN Change
Typically, the APN is auto-configured or auto-detected. The APN Change command allows you to
change the local telecommunication company. Enter AT command for changing APN in AT terminal as
follows: AT+CGDCONT=1,”IPV4V6”,”<your APN name>” and click the “Execute” button Figure 2.
Note: Use cid=1 for NA units and cid=3 for VZ units.
Examples:
•AT+CGDCONT=1,”IPV4V6”,”<your APN name>” for NA units
•AT+CGDCONT=3,”IPV4V6”,”<your APN name>” for VZ units

6. System Configuration –Linux-
6.1 Preliminary Check
First, the OS should detect the connected module as an NCM device. To force this check, create a file
named cdc_ncm.conf in the folder /etc/modprobe.d/ and insert the following line.
options cdc_ncm prefer_mbim=N
Assuming the module is using the default #PORTCFG=0 configuration and #USBCFG=0 mode.
Reboot the Ubuntu-PC, and plug the USB cable in. Use the dmesg command to check if the module is
recognized as a NCM device. The command response should contain something that looks like the
following:
dmesg<enter>

To send manually AT commands to the module, as shown in the next paragraph, you may use the serial
terminal emulation minicom. To install terminal emulation use the following command:
sudo apt-get install minicom<enter>
Assume that the module is using the default #PORTCFG=0 configuration. Enter one of the following
commands to use USB0 or USB3 port of the module, refer to Tab. 2.
sudo minicom –D /dev/ttyACM0<enter>
sudo minicom –D /dev/ttyACM3<enter>
6.2 NCM Activation on the Module
Assume that the module is using the default #PORTCFG=0 configuration, and the default #USBCFG=0
mode. Execute the following steps:
•USB cable is already plugged in, see previous chapter.
•Run the minicom serial terminal emulation connected to the USB0 port of the module
(/dev/ttyACM0 on Ubuntu side), see previous chapter.
•Enter the AT#PORTCFG=? Test command. If the entered command is not echoed, enter the ATE1
command to enable the echo.
Test command returns, for each Variant value, a short description on the logical connection regarding
physical serial ports/USBx ports and access points (AT parser instances, Trace), see below:
AT#PORTCFG=?
#PORTCFG: Variant=0: AT= USIF0 USB0 USB3; STT(Trace)= USB1
#PORTCFG: Variant=1: not supported by this product
#PORTCFG: Variant=2: not supported by this product
#PORTCFG: Variant=3: not supported by this product
#PORTCFG: Variant=4: not supported by this product
#PORTCFG: Variant=5: not supported by this product
#PORTCFG: Variant=6: not supported by this product
#PORTCFG: Variant=7: not supported by this product
#PORTCFG: Variant=8: AT= USB0 USB3 USB4; STT(Trace)= USB1
