1.2 Cabling and wires
Preparation
Take the 4 spacer fixing tabs provided with the device, and place them into the PCB holes as
shown in the picture.
Prepare a screwdriver, the 2 terminal blocks
provided with the device, and the stripped
wire pair necessary for connection, with
appropriate distinctive colors (power
connector –e.g. black-red, input-output wire
pairs –e.g. black-blue, alarm input –e.g.
black-white).
Connecting the inputs
The device has 2 input lines (IN1, IN2), where
external impulse-signal capable devices (meters) can be connected –e.g. water or gas meter -
by its wire pairs, in accordance with the standard connection method shown below, by fixing the
cable wire pairs for each input.
The input mode can be selected by the internal jumpers –beside the terminal block of the input
lines (3-3 pins for IN1, and 3-3 pins for the IN2) –according to the input line nr. titles.
Take care for the proper position of the jumpers. The contact (impulse) operation mode must
be also configured as well with the EasyTerm application.

6
Input line operation mode (selection by jumpers):
Contact mode (DRY)
oPut the jumper (CLOSE) on the IN1 or IN2 line’s 2-pins (two pair of pins),
each pair must be jumpered on the closer side of the terminal block
(connector) –as you can see in the picture.
Signal levels in DRY mode:
Contact resistance: 0 –1kOhm
Impulse signal frequency: 0 –500Hz
When the inputs are activated (IN1, IN2) the INx LEDs are signing the active (closed) status
during the operation, with the proper light and colour. See LED signals part.
EOL resistor (for DRY mode)
For the detection of wire cut, you have use and connect a 10kΩ resistor by parallel to
the contact.

7
Voltage mode (WET)
oPut the jumper on the IN1 or IN2 line’s 2-pins (two pair of pins), each pair
must be jumpered closer to the LED side –as you can see in the following
picture.
Signal levels (WET mode –voltage input):
Input high signal level: 8 - 24V
Input low signal level: 0 - 1V
Impulse signal frequency: 0 –500Hz
When the input were activated (IN1, IN2) the INx titled LEDs are signing the active (high signal
level) status during the operation, with the proper light and colour. See LED signals part.

8
Connecting the power supply
The 8-24V power-supply voltage (typically 12V
power adapter, or 24V power supply) can be
connected to the PWR input through a wire
pair. When connecting the power, the device
will be immediately started to operating, when
the PWR LED will indicate it with the
appropriate color/light.
Attention!
Do not forget to insert the SIM-card previously –see Chapter nr. 2. Pay close
attention to polarity! Holding the serials facing us, the right side of the PWR connector is the
positive pin and the left side is the negative pin!

Failure codes –for signing the device opreation troubles –in case of a failure, read the
Troubleshooting Chapter.
1 flash - Module failure
The serial connection is not operating properly between the module and the Easy 2S NB
board. After 1 minute, the device automatically tries to restart the module.
2 flashing - SIM card failure
Possible reasons:
othere is no SIM card inserted
oSIM card pinpad contact error
The device in this status will not continues its initialization, the receiving of serial port
commands is still active (for parametrizing). After 1 minute, the device automatically tries
to restart the module.
3 flashing - PIN authentication failure
Possible reasons:
owrong PIN code
oPUK code (security code) is necessary to give in
The device in this status will not continues its initialization, the receiving of serial port
commands is still active (for parametrizing). After 5 minutes, the device automatically
tries to restart the module.
4 flashing –The device cannot login to the GSM network
Error during the network registration. After 5 minutes the device restarts the modem
and retries.

11
5 flashing –the GPRS is allowed (GPRSEN=1), but the device cannot login to the
GPRS network
Possible reasons:
owrong APN settings
othe GPRS service is inactive for the SIM card
olow signal strength
othe RADIUS server is out of operation
omaintenance/service tasks by the M.O.
6 flashings –the device is registered to the cellular network, it has an IP address, but
cannot login to the server
Possible reason: the primary and the secondary server is not available/accessable
Visible sympthoms:
the opening of the TCP/UDP port was not succesful (e.g. wrong server
settings applied),
unsuccesful data sending
timeout when tries to receive data or wrong answer
The signal will be active, until the device will be succesfully signalling to a server.
IN1, IN2: Input #1, #2 is active - green
When the input contact is active (if the 2 pair wire closed) in case of high level of signal, the INx
LED will lighting according to the related input impulse contact. In case of low level its blank.
MDM RDY: Modem stand-by –red
During the inicialization the MDM LED blinks quickly (approx. twice per seconds). When the
modem is already accessible and operating and has an active communication on the GSM
network, then it will flashing with less frequency.

12
Main important signals of LED flashing/light:
not lights: the module was turned off
longer periodic flashing: 600 msec filling in / 600 msec filling out: the module not
registered to the network (possible causes: no SIM card, PIN authorization failure,
network search is in progress, login is in progress, etc.)
periodic short flashing: 75 msec filling in / 3 sec filling out: normal operation,
connected to the wireless network
continuously lights: voice call active (e.g. during wireless signal transmitting)
PWR: Power voltage active - green
Signs when the Easy 2S NB is under power and voltage and operating. When it has no light, the
Easy2 is powered off and has no active power source.
1.4 Operation requirements

Chapter 2. Installation of the device
Check the current firmware version of the device (SWVER value in the EasyTerm application). If
the version is not V23 R08 I09 NB or newer then refresh the firmware to the latest downloadable
version!
2.1 Installation on location, site
1. Take care that the device is not under power voltage, it is turned off and the LEDs
lights are not lighting or flashing before continue the following steps!
2. Mount the Narrow Band antenna (order option) to the SMA antenna connector, until
it sleeves. (In case of wired antenna find a place to the magnetic antenna and
connect it to the connector.)
3. Insert a SIM-card (in turned off status only!): insert and slide the SIM card
(provided by the Mobile Operator) into the metal SIM card bay at the direction when
the chip on the card looks down, and the MO logo looks upside, and the card’s cutted
corner looks to the PCB board. Push the card until it seize –until you will hear the
click of the holder (now it is fixed).
(Later, if you need to remove the SIM card, just push the SIM card edge –only in
turned off device status!)
4. Wire the cables pairs to the input terminal blocks (which will be required to
monitoring) Use the IN1, IN2titled input lines connectors (terminal block).
5. Connect the 12V/24V DC power - with the power chord of the alarm center (or by a
power adapter (12V min. 300mA) to the power plug’s terminal block (PWR titled).
Then the device will be under voltage, turned on and operating and its LEDs are
flashing according the proper operation –as listed in chapter 2.2.
6. You can setup the input lines with its jumper pairs behind the input lines (IN1, IN2).
The jumpers are used for interpreting the proper operation mode of the input line -
contact or voltage.
If you need to turn off the device: Disconnect and remove the power line or the power supply and
the device will be turned off.
2.2 Turning on the device
After starting the device further 2-4 minutes is required to coonect and able to transmit the signals.
The ready status will be signed by the status LEDs according to the following sequence step-by-step.

15
When the power voltage added, the devices turns on. The green PWR LED continuously
lights.
If the input(s) are wired then the IN1, IN2 LEDs are continuously lights with green.
Then later the MDM RDY LED blinks a several times with red, that the cellular modem is
started.
Soon the STA LED will be lightning intermittently a few times (3-times in a second with
some breaking between the light-sequences). Then the device loads and initializes the
system firmware.
Then the GSM LED (red) blinks a few times intermittently, which means that the cellular
modem network registration has started.
The yellow light of the STA LED signs that the network registration was succesful.
Then the device is operating related to the configuration parameter settings and it sends
data through and life signals through the network periodically.
For the further LED status signals see the LED signals table.
If you notice a different operation of the device, check Problem troubleshooting part.

Chapter 4. EasyTerm (configuration, software refresh)
4.1 Introducing the EasyTerm tool
The device is shipped with uploaded firmware and pre-defined factory configuration settings.
The customization of the configuration is possible by the EasyTerm® software (via micro USB
cable). This tool is suitable for checking and monitoring the current operation of the
communicator device or refresh its firmware.
According the needs, different configuration settings of the Easy 2S version are available for
download in pre-defined configuration files (for gate opening, alarm transmitting, IOs, etc).
The configuration file (CFG) can be uploaded to the device by the EasyTerm . Then the
parameter can be modified and saved to the device and into new CFG file –for later.
Uncompress the downloaded .zip file, execute EasyTerm.exe then startup screen will appear.

4.2 Connecting to the device
a.) USB connection
In the Connection settings window (1), at the Serial Port tab choose the proper and available
COM port for the Serial port field.
You can remotely access the device through celluar network at the TCP-IP tab. You also can Reset
Password, and monitorize the serial port through the terminal at Serial Monitoring tab.
When the device can be seen on the USB
serial port in the Connection window (1), at
the Serial Port the application will offer the
option to choose from the available COM ports.
The Password must be filled (by default the
password is „ABCD”, which will be filled
automatically). If you won’t change it, then just
leave it as it is –or fill the value password then push the Open for connecting.
Then the port opening messages will appear at the Terminal window (3), then soon the device and
modem, SIM identifiers in the Status part (2).
b.) Connecting through TCP IP (remotely)
In the Connection window (1) at the TCP-IP
tab you will found the necessary IP settings for
the GPRS (cellular network) connection.
Fill the SIM card IP address to the Device IP (get
the information from your mobile service
provider).
Fill the port number what you want to the field right from the Device IP . (The port number by default
is 9998). To the GPRS Login you have to fill the device IMEI last 5 character (you can read/copy
it from the left side at the IMEI coloumn).

19
By the REBOOTDAY parameter you can enable the industrial- and safety standard daily once
device restart event.
Push the Connect button for the cellular network
connection. (The button is active only if the USB serial
/ or TCP-IP connection is currently inactive (Close
status)).
(For login the necessary device IMEI and IP address
can be requested by the INFDEV or DEVSTAT SMS
text caommands.)
Hint: When you can connect on serial port, before
connecting it is useful to check the Serial Port tab
according to the description a.) shortly when the device will readout the value IMEI, IP data. Afterall
you can split the connection with the Close, then at the TCP-IP tab you can connect with the readout
data filling to the Device IP and GPRS Login fields.
When the device is trying to connect to the network,
you will see that the GSM STATE is yellow then
green - but the GPRS STATE –wireless network
access –is still not available (color yellow).
Later, when the network registration was fine and the
Narrow Band wireless network is accessible, the
GPRS STATE status will be also green.
After the successful connection…
When connecting, the signal strength diagram and
status pictograms will be grey for a short time. This means that currently there are no available status
and signal strength values.
Later the PIN/GSM/GPRS status –for the cellular
network reception - and signal (CSQ ) values will be
visible by colours.
During this time, the device transmits the life signal
and signal strength values frequently, according to
the settings.
When connecting to the cellular network, the Easy
2S NB checks the filled PIN code and will assign that
the password was accepter or not. (In case of PIN
failure it restarts the module.)

20
In case of any failure read the Troubleshooting chapter!
Status window (2):
When the „ connected ” title appears, this means that the serial connection to the device was
performed succesfully.
The „ disconnected ” assigns the disconnection of the device from the USB serial port,
which means that it is not available through the port (reconnect the cable and the device or
restart device when it is necesssary) –if the cable is already connected, then push the
Connect button for connecting.
When the EasyTerm is not necessary to use further, and you’d like to split the connection, then push
the Close button in the Connection window (1), and the serial connection will be closed
immeadiately (in case of GPRS connection, you can close the connection by the Disconnect button.
Remove the serial connector from the Computer.
If you will get the Login Failed message several time in the Terminal window (3), that means the
password you were filled in is wrong. Fill the proper password to the TCP-IP connection at the GPRS
Login and retry the connection.
Password reset:
On the Reset password tab, at the Password
field, fill or copy the IMEI’s middle 5
characters, then push the Reset button.
Then the Easy 2 password will be restored and
recovered to the ABCD default value.
Monitoring the serial port messages:
At the 4th tab, at the Serial Monitoring, you can Open it, and connect to the device in surveillance
(read only) mode, when only the left side of the window is active with the signal strength data and
terminal window messages.
This feature is provided for monitoring, checking
the Easy 2 current operation without any
intervention or configuration change.
Further details on the Chapter 4.4 .
When you are attempted to Close the
monitoring, after all you should click to the
Serial Port tab, for connecting the device for
parameter configuration.
