GPIO
Two General purpose input/output (GPIO) pins are available on the RJ45 connector that can             
be used to control a output relay or as a input for pulse counting or trigger events.
Power
The modem has a built in power supply capable of powering directly from main supply via               

Installation
Installing a SIM card
This model requires a MicroSIM card, which is supplied by your preferred service provider.             
To install the SIM card:
1. Locate the SIM card slot on the side of the modem. The slot is labeled SIM.
2. Push the MicroSIM card into the SIM card slot with the contact side facing down until               
you feel a light click.
3. Release the SIM card.
Installing the device
1. Connect a suitable antenna to the SMA connector.
2. Connect a RJ45 cable to the modem then connect the other end to the serial port on                
the application device.
3. Screw on the power cables into the power connection on the modem.
4. For a fixed installation, make sure the device is wired through a fuse box.
5. The blue status LED will start to blink according to the current state.
Mounting the device
The device can be secured under the meter terminal cover to limit possibility of theft and to                
protect from direct sunlight and moisture.
The devices should alternatively be mounted in a IP65 enclosure to protect it from direct              

Configuration
The M2M Smart Modem can be configured via SMS messages. After the M2M Smart             
Modem is powered up, the user can send a configuration SMS with the following             
configuration parameters.
Parameters are delimited by a [ENTER] or semicolon [;]
Each configuration parameter consists of a key and value except for the RESET and INFO              

Multiple parameters can be sent together in one SMS message.
