IMPORTANT! Cellular devices operate using radio signals and cellular
networks. Connections cannot be guaranteed, at all times, under all conditions.
Therefore, you should never rely solely upon any wireless device for essential
communications, for example emergency SMS alarms. Remember, in order to
make connections/calls the cellular terminal or mobile must be switched on in a
service area with adequate cellular signal strength.
There are different guidelines and standards around the world that govern the
permitted levels of radio frequency exposure for the general population. The
Specific Absorption rate (SAR) is a measure of the rate at which radio
frequency energy is absorbed by the body when exposed to radio frequency
electromagnetic fields.
MTX cellular devices are approved for use in applications where the antenna is
placed more than 21cm from the body. For other applications, the integrator is
responsible for compliance with local SAR requirements.
Operating Characteristics
Parameter

25-35mA
Idle, typical COM1 DB9 connected
1
40-50mA
Transmitting, typical with good signal
2
130-160mA
Recommended Minimum Power Supply Size

1. When idle there will be short spikes of higher current draw associated with network activity such as checking for messages.
2. Values given are typical average current draw with good signal, short term spikes may be significantly higher, poor signal will
significantly increase power consumption.
Device Capabilities
This tool and the device, allows the user to achieve the following:
1. SMS alarm from 3 digital inputs and or 2 analogue inputs to up to 10 phone numbers
2. SMS alarm based on a temperature limit when using our serial temperature sensor accessory
3. SMS control using digital outputs to drive a relay (by others). For example – starting/stopping an
irrigation pump.
4. Set custom aliases for certain commands, for example PumpOn to turn and pump on using an
output
The MTX-4G-JAVA-IoT (AUS) with MTX Tunnel used as an SMS Alarm, is capable of much more
than outlined in this manual and associated configuration tool – contact Australis M2M Pty Ltd to
discuss additional capabilities.
