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 26.6cm or more from human body.
– Do not put the antenna inside metallic box, containers, etc.
Using the modem in vehicle
– Check for any regulation or law authorizing the use of GSM in vehicle in your country before installing the
modem.
– Install the modem by qualified personnel. Consult your vehicle dealer for any possible interference of electronic
parts by the modem.
– The modem should be connected to the vehicle’s supply system by using a fuse-protected terminal in the
vehicle’s fuse box
– Be careful when the modem is powered by the vehicle’s main battery. The battery may be drained after extended period.
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/rain, high temperatures, 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.

Hardware installation
3.1
Mounting the modem
If delivered with the DIN clip accessory, detailed on page 23, use two M3 screws to mount the DIN clip on the back
of the modem as shown on figure 3.1.1.
Figure 3.1.1: DIN clip mounted on M100 2G
3.2
Installing the SIM card
Use a ball pen or paper clip to eject the SIM holder by pressing the eject button. Put the SIM card to the tray; make
sure it is completely inserted in the tray, then carefully put back the tray into the slot.
Note: DO NOT pull out the SIM holder without pushing the ejector button.
3.3
Connecting the external antenna (SMA type)
Connect an antenna with SMA male connector on the modem, make sure the antenna is tightly secured. Select an
antenna with the right GSM frequency and an impedance of 50Ω; incorrect antenna will affect communication and
even damage the modem.
Note: Respect a safety distance of at least 26.6cm to the antenna during the modem operation.
3.4
Connecting the modem to external device
Use Maestro standard DB15 to DB9 straight cable, detailed on page 23, to connect an external controller or a
computer. Refer to section 5.2 for more details on some other cable option or adapter.

Note: If the Maestro 100 2G is connected with another DCE device please use a cross cable.
3.5
Connecting the DC power supply
If delivered with the power cord accessory, on page 22, use the open ending of the power cord to connect a DC
supply. Refer to the following for power supply requirement:
– Input voltage range : 5-32V
– Rated current: 650mA
Figure 3.5.1: Power cord not included in the package
Plug the DC Molex connector of the power cord in the modem and it will turn on automatically. The status indicator
led will light when power is applied. After few seconds it will blink slowly, meaning the modem is registered on the
network.

General Purpose Input/Output port
/!\ Important notice: The following commands are from Generic AT command guide and will work only
if the Maestro SmartPack is disabled (AT+SPMODE=1). Else please refer to the SmartPack user manual
to control GPIOs through SmartPack AT commands.
This port can be configured as either an input or an output and is mapped to GPIO1 in the internal micro-controller.
– To setup this port as an input, type AT+WIOM=1,"GPIO1",0 on the serial port. Then to read the status of
the input, type AT+WIOR="GPIO1". +WIOR: 0 means input is below 0.8V, while +WIOR: 1 means a positive
voltage higher than 2V and no more than 3.3V. Higher voltages will damage the unit.
Note: Please note that the input port is put by default to High status internally, so you just need
to short it to the ground to make it low, and open to make it high. See below example:
AT+WIOM=1,”GPIO1”,0 ;Configure as input
AT+WIOM=4 ;Save configuration
AT+WIOR="GPIO1" responds +WIOR: 1 ;Just leave I/O pin open
AT+WIOR="GPIO1" responds +WIOR: 0 ;While shorting I/O to ground

25
– To setup this port as an output, type AT+WIOM=1,"GPIO1",1 on the serial port. Then set the state of the output
with AT+WIOW="GPIO1",0 for 0V, or AT+WIOW="GPIO1",1 for 2.8V.
26

6.3
Analogue input port
/!\ Important notice: This section concern only OpenAT developer that will need to control ADC from their
application, else the Maestro SmartPack will control analogue input through SmartPack AT commands.
This port can be used either as a voltage input (0-5V range) or as a current input (0-20mA range).
– To setup the port as a voltage input, issue the commands: AT+WIOM=1,"GPIO19",1 then AT+WIOW="GPIO19",0.
– For a current input, issue: AT+WIOM=1,"GPIO19",1 then AT+WIOW="GPIO19",1.
To read the value of the input, use the command AT+ADC?. More information can be found in the AT commands
guide document.
Note: The analogue input use an ADC with a 10-bit resolution.
6.4
RS232 auto-online mode (power saving)
When on auto-online mode, the RS232 transceiver will shut down most of its hardware, to save power, if it does not
detect a valid input for more than 100µs.
The RS232 transceiver will wake up when valid input is detected again.
By default, auto-online mode is not active. To activate it, issue AT+WIOM=1,”GPIO22”,1,0 followed by AT+WIOM=4.
This setting needs to be set once, and will be saved in memory.
