1. General
TCG140-4 is a 4G LTE Cat.1 universal I/O module. It supports also 3G and 2G wireless
communicaon and provides data connecvity on LTE-FDD, DC-HSDPA, HSPA+, HSDPA, HSUPA,
WCDMA, EDGE, and GPRS networks.
It has 2 digital inputs, 4 analog inputs, digital interfaces for external sensors, and 4 relays. Two
of the analog inputs can be switched either in a current loop (0-20mA) or voltage modes. The relays
can be acvated either remotely (via SMS or HTTP API command) or locally - from the status of the
monitored parameter.
TCG140-4 supports all digital sensors of Teracom.
All monitored parameters and status of relays can be periodically saved in the embedded data
logger. It is possible to arrange records on any alarm condion.
The module supports HTTP API for M2M communicaon.

3. Powering
TCG140-4 is designed to be supplied by adapter SYS1308-2412-W2E (12V/2.0A) or similar,
intended for use in the condions of overvoltage category II, and priorly assessed for compliance
with safety requirements. The power supply equipment shall be resistant to short circuit and
overload in a secondary circuit. When in use do not posion the equipment so that it is dicult to
disconnect the device from the power supply.

4. LED indicators
LED indicators show the status of the module:
• REL1 - REL4 (green) – the LED is ON when the corresponding relay is activated (the NO
contact is connected to COM);
• SIG (red) – indicates the status of the device together with STA;
• STA (yellow) – indicates the status of the device together with SIG.
The following states are displayed:
• Module inializaon – aer power-on and rmware update SIG and STA turn ON for a
second, aer this turn OFF for another second;
• Searching for GSM network – aer a successful inializaon, SIG is OFF, STA ashes on
200mS (ash period 200ms);
• Connected to GSM network – aer a successful connecon to a mobile network, STA
shows the type of connecon, while SIG shows the signal strength:
- STA ashes ones for 200mS in a period of 2S – there is a GSM connecon only
- STA ashes twice for 200mS in a period of 2S – there is GSM and 4G/3G/2G
connecon
At the same me SIG has 5 states:
- SIG ashes 1 me in a period of 2S – signal strength is between 0 and 20%;
- SIG ashes 2 mes in a period of 2S – signal strength is between 21 and 40%;
- SIG ashes 3 mes in a period of 2S – signal strength is between 41 and 60%;
- SIG ashes 4 mes in a period of 2S – signal strength is between 61 and 80%;
- SIG is solid ON – signal strength is between 81 and 100%.
• Error message – in case of error aer inializaon, SIG will stay solid OFF, STA will ash
showing the type of error.
- STA ashes ones for 1S – master phone number is not set;
- STA ashes permanently for 1S in a period of 2S – permanent hardware error.
A more detailed descripon of the I/O module states is shown in the user manual.
5. Installaon
This device must be installed by qualied personnel. The installaon consists of mounng
the device, connecng inputs and outputs, providing power, conguring via a web browser, and
connecng to the mobile network. This device must not be installed directly outdoors.
Aenon! Disconnect the power supply before wiring.
Make sure that wires are properly aached to the terminals and that the terminals are
ghtened. Not proper wiring and conguraon can cause permanent damage of TCG140-4 or the
equipment to which it is connected or both.
It is recommended to test and congure TCG140-4 without any controlled device.
Aenon! Before installing the SIM card in the card slot, please ensure that the PIN code is
disabled.

7. Inial setup via USB
The inial setup of TCG140-4 is done with a computer running Windows 7 or newer Microso
Windows operang system. Aer power-up, the module should be connected to the computer
with a USB cable. Once the USB cable is connected, the operang system automacally starts to
install the drivers for the communicaon with the device. The following message appears:
The following drivers will be installed:
• Microchip composite device;
• USB serial port driver.
If for some reason the USB serial port driver cannot be installed automacally, it must
be installed manually. The driver can be downloaded from the TCG140-4 product page at
www.teracomsystems.com. Aer successful driver installaon, the device will be recognized as
Mass storage, the following window appears on the screen:
The only le stored on the mass storage is a tool called “TCong”. This tool enables
communicaon between the TCG140-4 and PC. Aer starng the TCong tool, the following
program will appear:
Pressing the “Start” buon will open the web browser and display the web interface of
TCG140-4. The “Monitoring” page displays the current state of the sensors, digital inputs, analog
inputs, and relays. The setup of the module is made in the “Setup” menu. A detailed descripon of
the setup process can be found in the user manual.

8. Setup via SMS
TCG140-4 supports up to 5 SMS users (Master + 4 users). The Master is able to congure some
of the system parameters by SMS messages as well as to receive alarm and status messages. The
rest 4 SMS users are able only to receive alarm and status messages. Messages from unauthorized
numbers are ignored by the module. The complete list of the supported SMS messages can be
found in the User manual.
9. Firmware update
TCG140 module supports rmware update over USB or Internet.
9.1. Firmware update over USB
To update the device over the USB, follow the steps below:
• Connect the device to PC with a USB cable;
• Start TCong program from aached removable disk and open the device web interface;
• Go to Setup->System->Firmware update;
• Press “Choose le” buon and select the update le (.cod extension);
• Press “UPLOAD” buon.
The rmware will be uploaded and veried, the procedure takes about a minute. If the le
is correct, the following message will appear: “Upload Successful. Please wait while updang...”.
The “Update” procedure takes about 2 minutes. Once the update is complete, the browser will be
redirected to the monitoring page.
Aenon! Don’t turn o the power supply during the update. Turning o the power supply
will damage the device.
9.2. Firmware update over the Internet
To update the device over the Internet follow the steps below:
• Upload the update le (.cod extension) on public HTTP server;
• Send rmware update command (the syntax of the SMS message is described in the
“Device setup via SMS” secon in the user manual). Please note that only the Master
can send this message.
The update le will be transferred and veried. The procedure takes about 3 minutes. If the
le is correct, the Master will receive a conrmaon SMS message. The “Update” procedure takes
about 2 minutes. Once the update is complete, TCG140-4 will restart.
Aenon! Don’t turn o the power supply during the update. Turning o the power supply
will damage the device.
10. Factory default sengs
TCG140-4 can be restored to its original factory default sengs, following the steps below:
RESET
• Turn o the power supply;
• Press and hold the RESET buon
then turn on the power supply;
• STA and SIG LEDs will turn on;
• Release the RESET buon.
The module will restore its default sengs.
