1. INTRODUCTION
1.1 Description
The MTX-IND-V2 is a GSM-GPRS terminal modem based on the Cinterion TC65i module. It has many
industrial environment features and is enclosed in a waterproof IP65 housing.
The MTX-IND-V2 is the perfect choice for applications that are installed outdoors and need a mains AC
power supply, to control high loads and communicate with RS232-RS422-RS485 serial bus.
The MTX-IND-V2 terminal is able to handle data calls, SMS, Fax, and GPRS connections with its powerful
TCP-IP stack communication with Internet Services: TCP, UDP, HTTP, FTP, SMTP, POP3.
The MTX-IND-V2 includes Java embedded programmability and a full range of I/Os. The unit can host and
control your Java J2ME application allowing you to develop and embed your code directly inside,
shortening time to market and reducing costs. The new internal Watchdog supervisor avoids hangs-up.
Alternatively, it can be used as a powerful standalone GPRS modem with its intrinsic TCP/IP stack.
The MTX-IND-V2 can host and control your Java J2ME application allowing you to develop and embed your
code directly inside, shortening time to market and reducing costs, minimizing the need for further
hardware components and making your M2M application easy to integrate.
RF 868MHz radio frequency WaveCard (Coronis) modules can be connected to the internal TC65i ASC1
port to create an RF network and concentrate in this GSM/GPRS unit. Remote units with low power RF
Wavesense are also available.
The Ethernet module can also be connected to the TC65i ASC0 and make ETH-GSM gateways. All these
features need to be JAVA programmed. If you would like a WIFI link instead of cable installation, it is
possible to have this if another module is connected to the ASC0. WIFI and Ethernet cannot be installed at
same time. By default, the Ethernet module is soldered to put CAT5 in the cable gland but, on request, it is
also possible to solder the RJ45 connector outside the box.
Other peripheral (check ordering information) are 4 relays 1C type capable to switch up to 8 Amp loads.
They’re connected to 4 GPIOs and can be controlled by AT commands or JAVA embedded programs. There
are another 2 configurable TTL/CMOS input/output GPIOs and 2 optoisolated differential inputs/outputs.
With quad band 900/1800 MHz and 850/1900 MHz, your applications can be used all over the world.
The MTX-IND-V2 is RoHs, WEEE, FCC and CE compliant. It is manufactured with the ISO 9001 & IS0
14001 Quality certifications.
A full list of antennas, cables supplies and accessories are available.
The MTX-IND-V2 incorporates a Cinterion WM TC65i module.
Note! Some of the functions described inside this Technical Description are only possible when the SIM-
Card is inserted.

1.4.4 GPRS Multi-Slot Support
GSM Multi-slot classes supported by MTX-IND-V2
1.4.5 Power Consumption
The table below briefly summarizes the various operating modes referred to in the following chapters.
Normal operation
GSM / GPRS SLEEP
Various power save modes set with AT+CFUN command. Software is active
to minimum extent. If the Terminal was registered to the GSM network in
IDLE mode, it is registered and paging with the BTS in SLEEP mode, too.
Power saving can be chosen at different levels: The NON-CYCLIC SLEEP
mode (AT+CFUN=0) disables the AT interface. The CYCLIC SLEEP modes
AT+CFUN=7 and 9 alternately activate and deactivate the AT interfaces to
allow permanent access to all AT commands.
GSM IDLE Software is active. Once registered to the GSM network paging with BTS is
carried out. The Terminal is ready to send and receive.
GSM TALK
Connection between two subscribers is in progress. Power consumption
depends on network coverage individual settings, such as DTX off/on,
FR/EFR/HR, hopping sequences, antenna.
GPRS IDLE
Terminal is ready for GPRS data transfer, but no data is currently sent or
received. Power consumption depends on network settings and GPRS
configuration (e.g. multi-slot settings).
GPRS DATA
GPRS data transfer in progress. Power consumption depends on network
settings (e.g. power control level), uplink / downlink data rates, GPRS
configuration (e.g. used multi-slot settings) and reduction of maximum
output power.
ULTRA LOW
POWER MODE
Shutdown after sending the AT^SMSO command. The RTC works continuously, but the software is not
active. Interfaces are not accessible.
Airplane mode
Airplane mode shuts down the radio part, causes the Terminal to log off from the GSM/GPRS network
and disables all AT commands whose execution requires a radio connection. Airplane mode can be
controlled by the AT commands AT^SCFG and AT+CALA: With AT^SCFG= MEopMode/Airplane/OnStart
the Terminal can be configured to enter the Airplane mode each time when switched on or reset. The
parameter AT^SCFG=MEopMode/Airplane can be used to switch back and forth between Normal mode
and Airplane mode any time during operation. Setting an alarm time with AT+CALA followed by
AT^SMSO wakes the module up into Airplane mode at the scheduled time.

All electrical connections to the module are protected in compliance with the standard air and contact
Electrostatic Discharge (ESD).
3.1 Power
Pin 1 and 2 are used to power the MTX-IND-V2. It can be VDC or VAC powered without needing to
configure anything. Just apply the VCC or VAC voltage.
The supply voltage, VCC or VAC required by the modem is in the range 120-370 VDC and 90-264 VAC. The
power supply has to be a single voltage source capable of providing a peak during an active transmission.
The uplink burst causes strong ripples (drop) on the power lines.
Application of the supply voltage does switch the modem on.
Automatic restart after shutdown feature:
This allows an application to always be switched on; it will be able to restart by itself.
The terminal will not need an external ignition to be powered up and it will be powered up 100% time if
power is applied. An internal LED will light when power is present.
The MTX-IND-V2 can charge an internal Ion-Li 3.7V 1600mA/h battery which means that it can operate for
a few hours without external power. When external power is applied, the battery is being charged.
Note. It is possible to apply power at the 1-2 pins and 3-GND at the same time. This allows you to connect
a sealed battery on pin 3 so it will be able to operate if there is a fault with the mains.
Output 24VDC at pin 4 is only present when mains power is applied.

3.3 Mini USB Connector
The MTX-IND-V2 supports a USB 2.0 Full Speed (12Mbit/s) device interface. The USB interface is primarily
intended for use as a command and data interface and for downloading firmware. The USB I/O pins are
capable of driving the signal at min 3.0V. They are 5V I/O compliant.
The USB port has different functions depending on whether or not Java
is running. Under Java, the lines may be used for debugging purposes.
If Java is not used, the USB interface is available as a command and
data interface and for downloading firmware.
The USB I/O-pins are capable of driving the signal at min 3.0V. They
are 5V I/O compliant. To properly connect the module’s USB interface
to the host a USB 2.0 compatible connector is required. Furthermore,
the USB modem driver delivered with the MTX-IND-V2 must be installed as described below.
The USB host is responsible for supplying power to the terminal USB interface, across the VUSB_IN line.
There are drivers available for Windows environment applications. Visit MTX-IND-V2 ftp at:

3.4 Antenna Connector
The antenna connector allows transmission of radio frequency (RF) signals between the modem and an
external customer-supplied antenna. The modem is fitted with a 50, SMA female coaxial jack. It is IP65
protected.
The MTX-IND-V2 can also accommodate internal antennas. Just unplug the U.FL connector from Cinterion
TC65i and plug the U.FL connector into an internal antenna. We recommend EAD QUINTUS but other
models are available.
The external antenna must be matched properly to achieve best performance regarding radiated power,
modulation accuracy and harmonic suppression.
It is possible to operate with the external antenna and the internal antenna at same time, a special SMA
switch connector must be used (given on request). When the external antenna is screwed, the internal one
is disconnected.
3.5. SIM card reader
The MTX-IND-V2 Terminal is fitted with a SIM card reader designed for 1.8V and 3V SIM cards.

The card holder is a six wire interface according to GSM 11.11. Two pins have been added to detect
whether or not the SIM card drawer is inserted.
Removing and inserting the SIM card during operation requires the software to be reinitialized. Therefore,
after reinserting the SIM card it is necessary to restart MTX-IND-V2 Terminal.
The full operation of the MTX-IND-V2 relies on a SIM card being inserted. Some MTX-IND-V2 functionality
may be lost if you try to operate the control terminal without a SIM card.
3.6 MAIN Serial Interface Port ASC0 RS232/RS485/RS422
The modem by default supports a standard RS232 serial interface (EIA/TIA 574) via the following block
pins shown below:
The RS232 can be changed to RS485 and RS422 interfaces with internal jumpers selectors.
The RS485 and RS422 can be configured as open bus or ended with a 120 ohm resistor.
