1: Introduction
mPACK Command Reference M110 Series Cellular Modem 7
1 Introduction
The aim of this document is to provide users of Lantronix M110 Modems running mPACK, a detailed
description of the commands supported by mPACK and various configuration / operation modes in
which M110 series Modems could be used.
Safety Precautions
1.1.1 General Precautions
•The modem generates radio frequency (RF) power. When using the modem, care must be
taken on safety issues related to RF interference as well as regulations of RF equipment.
•Do not use the modem in aircraft, hospitals, petrol stations or in places where using GSM
products is prohibited.
•Be sure that the modem will not be interfering with nearby equipment. For example:
pacemakers or medical equipment. The antenna of the modem should be away from
computers, office equipment, home appliances, etc...
•An external antenna must be connected to the modem for proper operation. Only used
approved antennas with the modem. Please contact authorized dealer on finding an approved
antenna.
•Always keep the antenna with minimum safety distance of 26.6 cm or more from human body.
•Do not put the antenna inside metallic box, containers, etc.
1.1.2 Protecting your modem
To ensure error-free usage, please install and operate your modem with care. Remember the
following:
•Do not expose the modem to extreme conditions such as high humidity/temperatures, rain,
direct sunlight, caustic/harsh chemicals, dust, or water.
•Do not try to disassemble or modify the modem. There is no user serviceable part inside and
the warranty would be void.
•Do not drop, hit, or shake the modem. Do not use the modem under extreme vibrating
condition.
•Do not pull the antenna or power supply cable. Please attach or detach by holding the
connector.
•Connect the modem only according to the instruction manual. Failure to do it will void the
warranty.
M110 series supported by mPACK
Please consult Lantronix sales for the most updated information.
Uplink / Downlink maximum data rates:
•3G: 5.76 / 7.2 Mbps
•NB-IoT: 62.5 / 27.2 kbps
•LTE-M1: 375 / 375 kbps
•LTE cat. 1: 5 / 10 Mbps

2: Basic Operation
mPACK Command Reference M110 Series Cellular Modem 8
2 Basic Operation
Modes of Operation
M110 running mPACK can be operated in the following modes:
•PPP Dial up over RS232 (Linux)
•PPP Dial up over USB (Linux)
•Generic AT commands over RS232
•Generic AT commands over USB
•mPACK commands over RS232
•mPACK commands over USB
•Note: For Generic AT command over USB operation use either AT#USBATCOM or
AT#USBMODE commands. For PPP dial over USB, use AT#USBMODE only.
•PPP Dial up over USB is not available for M111 and M115 variants.
Thanks to the wide range of operating modes, mPACK transforms the M110 Modem into a versatile
modem which can provide data connectivity to serial devices in almost any situation be it an Intelligent
connected serial device with full TCP/IP stack capable of PPP connection or an intelligent connected
serial device capable of sending commands but without a TCP/IP stack or be it a non-intelligent
connected serial device only pumping out data on serial port.
In addition, a function of mPACK as listed below provides extra functionality and improves the
robustness of the wireless connected system.
•Automatic and self-recovery TCP/UDP socket connection
•AT command driven TCP/UDP socket connection
•Ping Service
•Network Watchdog
•Input/output and Analog triggered AT command
•Remote AT command through SMS and TCP Terminal
•Remote program updating
•Socket data sending
Getting Started
Before putting the M110 in operation, it must be configured first. The configuration commands can be
given to the modem over Serial port or by sending an SMS.
To send command over the serial port, please connect M110 to a computer over Serial port. Use
standard software available on a Windows PC (e.g., hyper terminal) to send serial commands to
M110. SMS would have to be sent to the mobile number corresponding to the SIM card inserted in
M110 device. In either case, the commands are mPACK AT commands as described below.
Default Settings
The default settings of the UART and USB ports are as follows:
•Baud rate: 115200
•Character Framing: 8
•Parity: None
•Stop Bit: 1
•Flow Control: None

2: Basic Operation
mPACK Command Reference M110 Series Cellular Modem 9
Basic Command Syntax
All commands starting with AT+ entailed in documents:
•u-blox-ATCommands_Manual_(UBX-13002752) for M111, M114, M115
•SARA-N2_ATCommandsManual_UBX-16014887 for M112, and
•SARA-R4_ATCommandsManual_(UBX-17003787) for M113
All mPACK commands start with AT# are the only ones covered in this document, e.g.
AT#INFO
Error codes for uBlox commands are as described in the uBlox AT command manual
Error codes for mPACK commands are as follows:
•“ERROR BAD PARAMETER” for wrong parameters or out of range values
•“ERROR UNKNOWN COMMAND” for wrong command syntax
LED Status Indicator
The LED will indicate different status of the modem:
•For Orange LED:
•OFF: No cellular connection
•ON: Cellular connection
•Blinking: Data transfer
•For Green LED:
• OFF: No power
• Slow blink: No signal or CSQ < 4,99
• Fast blink: Bad CSQ < 9
• ON: Good signal or CSQ > 10
Factory Reset
To factory reset the device, hold the reset pin for 15 to 20 seconds.
• Initially both LEDs are off
• After 5 seconds the green LED will go on (and the orange LED remains off)
• After 15 seconds the orange LED will go on (and the green LED goes off)
Note: If the time elapsed is more than 20 seconds, the device will reboot without doing factory
reset.
