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
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.
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.

Chapter 1. Introduction
M110 Series Cellular Modem mPACK Command Reference 8
2: Basic Operation
2.1 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
Thanks to the wide range of operating modes, mPACK transforms the M110 Modem into a versatile modem
which is capable of providing 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 greatly 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
2.2 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.
M110 Series Cellular Modem mPACK Command Reference 9
2.3 Default settings
The default settings of the UART and USB ports are as follows:
– Baudrate: 115200
– Character Framing: 8
– Parity: None
– Stop Bit: 1
– Flow Control: None
2.4 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
2.5 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
M110 Series Cellular Modem mPACK Command Reference 10
2.6 Factory reset
To factory reset the device, hold the reset pin for over 30 seconds.
– Initially both LED’s are off
– After 5 seconds the green LED will go on (and the orange LED remains off)
– After 30 seconds the orange LED will go on (and the green LED goes off)

mands (usually beginning with AT+, or just AT) at one time, but not both. In order to enter the other
set of command, the user need to use AT#PASS to switch between the 2 modes:
M110 Series Cellular Modem mPACK Command Reference 15
Chapter 3. Administration Commands
• PASS mode set to 0 : pass-through mode disabled; only mPACK commands are accepted.
• PASS mode set to 1 : pass-through mode enabled; only u-Blox commands are accepted.
– If pass-through mode is disabled (can check with AT#PASS?) and enabling pass-through mode is
desired:
• AT#PASS=1 to change to pass-through mode
– If pass-through mode is enabled (cannot check with AT#PASS?, which returns ERROR, as this is not
u-Blox command), and exit pass-through mode is desired:
• Issue +++ (and the modem should exit pass-through mode)
• AT#PASS=0 to make the switch permanent (otherwise, the modem will be in pass-through mode
again when it restarts)
AT#PASS=(flag)
– flag: 0 to disable pass through mode, 1 to enable. Default 0
