1. Short description
TCG120 is a GSM-GPRS remote monitoring controller for distributed IO monitoring and control. The
controller has 2 digital inputs, 2 analog inputs, and 1-Wire interface. The controller supports up to 4
Teracom humidity and temperature 1-Wire sensors. The device has 2 relays with normally open and
normally closed contacts.
The relays can be activated either remotely (via SMS or HTTP API command) or locally - from the status
of the monitored parameters. Only one parameter can control the relay at the same time, but for each
parameter, an email or SMS can be sent on an alarm condition.
TCG120 may periodically send data to a remote server, which makes it suitable for client-server
monitoring and control systems.

5. Installation
This device must be installed by qualified personnel. The installation consists of mounting the device,
connecting to the GSM network, connecting inputs and outputs, providing power and configuring via a
web browser. This device must not be installed directly outdoors.
Attention! Before installing the SIM card in the card slot, please ensure that the PIN code is
disabled.
5.1. Mounting
TCG120 should be mounted in a clean and dry location on a not flammable surface. Ventilation is
recommended for installations where the ambient air temperature is expected to be high.
Mount the device to a wall by using two plastic dowels 8x60mm (example Würth GmbH 0912
802 002) and two dowel screws 6x70mm (example Würth GmbH 0157 06 70). Attach the screws to
the surface vertically. See Appendix C, fig. 1 for mechanical details.
Maintain spacing between adjacent equipment. Allow 50 mm of space on all sides, as shown in fig.2
in Appendix C, this provides ventilation and electrical isolation.
5.2. Connectors
Attention! Disconnect power supply before wiring.
The correct wiring procedure is as follows:
Make sure power is turned off;
Make wiring connections to the terminals;
Apply power.
It is recommended to test and configure TCG120 without any controlled device.
TCG120 _R1.9 - October 2018 Page 5
Make sure that wires are properly attached to the terminals and that the terminals are tightened.
Not proper wiring and configuration can cause permanent damage of TCG120 or the equipment to
which it is connected or both. Inputs and outputs locations are shown below:

* Operating mode is selected by jumper DI1/DI2 - closed for “dry contact” and open for “logic level”.
By default, jumpers are closed.
5.2.1. Power supply connection
TCG120 is designed to be supplied by adapter SYS1308-2412-W2E or similar, intended for use in
the conditions of overvoltage category II. The power supply equipment shall be resistant to short
circuit and overload in the secondary circuit.
When in use, do not position the equipment so that it is difficult to disconnect the device from the
power supply.
5.2.2. Digital inputs connection
Attention! Digital inputs are NOT galvanic isolated.
The TCG120 digital inputs can be used in two modes –“dry contact” and “logic level”. The mode is
determined by the jumper, close to the corresponding input. To change the operation mode, the
plastic enclosure must be opened. Closed jumper determines “dry contact” mode while open
“logic level”. By default digital inputs are in “dry contact” mode.
In “dry contact” mode digital inputs can be used to monitor the state of a discrete device –door
contact switch, push button, PIR detector etc.
The following picture illustrates how a dry contact switch can be connected to the input (or inputs)
of TCG120. One side of the contact is connected to “Digital In” and the other side is connected to
“GND” terminals.
The maximum cable length for a digital input should be up to 30 meters.
TCG120 _R1.9 - October 2018 Page 6
5.2.3. Analog inputs connection
Attention! Analog inputs are NOT galvanic isolated.
Analog inputs of TCG120 can be used for monitoring of DC voltage up to 60VDC. They can be
connected directly to batteries, solar panels, power supplies etc.
Built-in functionality “Multiplier”, “Offset” and “Dimension” for every analog input gives the
possibility to monitor sensors with analog outputs and see directly the measured parameter. It is
also possible to monitor voltages higher than 60 VDC with external resistive dividers.
The following picture illustrates how a battery can be connected to the analog input of TCG120.
One side of the contact is connected to “Analog In” and the other side is connected to “GND”
terminals.
The maximum cable length for a digital input should be up to 30 meters.
5.2.4. Sensor connection
The device supports TST1xx, TST2xx and TSH2xx temperature and humidity-temperature sensors.
Up to 4 1-Wire sensors can be connected to the controller.
1-Wire is a registered trademark of Maxim Integrated Products, Inc. It is designed to connect
several sensors over a short wiring. It is not suitable for long distances or environments with EMC
TCG120 _R1.9 - October 2018 Page 7
interference. We recommend reading Maxim’s 1-Wire tips at http://www.maxim-ic.com/app-
notes/index.mvp/id/148.
The sensors have three wires –positive voltage (+VDD), ground (GND) and bidirectional data
(Data). The colors of wires for every sensor are specified in its user manual.
It is strongly recommended to use “daisy-chained” (linear topology) for multiple sensors:
“Star” topology can be used only as a last resort for up to 4 sensors and total cable length up to 10
meters:
There are many parameters which determine the maximum length of the wires - type of cable, the
number of sensors, ambient electromagnetic noise and sensor network topology.
It is strongly recommended to use only UTP/FTP cables and keep total cable length up to 30 m.
Although functionality has been achieved in the longer distance, we cannot guarantee error-free
operation over mentioned wiring length.
We guarantee proper operation only with Teracom 1-Wire sensors.
TCG120 _R1.9 - October 2018 Page 8
5.2.5. Relay connection
The relay contacts are internally connected directly to the terminal connectors. For all relays
normally open, normally closed and common contacts are available. For loads with higher
switchable current/voltage than specified, an external relay should be used.
When mechanical relays switch inductive loads such as motors, transformers, relays, etc., the
current will arc across the relay contacts each time the contacts open. Over time, this cause wears
on the relay contacts which shorten their life. When switching an inductive load, it is
recommended that relay contact protection devices are used.
6. LED indicators
LED indicators show the status of the controller:
REL1 –REL2 (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:
Controller initialization –after power-on and firmware update SIG and STA turn ON for a
second, after this turn OFF for another second.
Searching for GSM network –after initialization, SIG is OFF, STA flashes (flash length –
200ms)
Connected to GSM network –after successful connection to a mobile network, STA shows
the type of connection, while SIG shows the signal strength.
STA flashes ones for 200mS in period of 2S –there is GSM connection only;
TCG120 _R1.9 - October 2018 Page 9
STA flashes twice for 200mS in a period of 2S –there is GSM and GPRS connection.
At the same time SIG has 5 states:
SIG flashes 1 time in period of 2S –signal strength is between 0 and 20%;
SIG flashes 2 times in period of 2S –signal strength is between 21 and 40%;
SIG flashes 3 times in period of 2S –signal strength is between 41 and 60%;
SIG flashes 4 times in 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 after initialization, SIG will stay solid OFF, STA will flash
showing the type of error.
STA flashes ones for 1S –master phone number is not set;
STA flashes permanently for 1S in a period of 2S –permanent hardware error.

7. Initial setup via USB
The initial setup of TCG120 controller is done with a computer running Windows 7 or newer Microsoft
Windows operating system. After power-up, the controller should be connected to the computer with
USB cable. Once the USB cable is connected, the operating system automatically starts to install the
drivers for the communication 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 automatically, it must be installed
manually. The driver can be downloaded from the TCG120 product page at www.teracomsystems.com.
After successful driver installation, the device will be recognized as Mass storage, the following window
appears on the screen:
The only file stored on the mass storage is a tool called “TConfig”. This tool enables the communication
between the TCG120 and PC. After starting the TConfig tool, the following program will appear:
Pressing the “Start” button will start your web browser and display the Monitoring page of your TCG120
controller.
