devices with SMS, GSM / GPRS communication and the possibility to control by calling.
The unit is programmed using a PC and software control panel via a USB connector It
contains 7 binary inputs (one is internal and monitors power supply voltage, inputs 1 to 4
can be used as analogue), 3 outputs - open transistor collector (outputs 1 and 2 inputs are
combined with binary inputs 6 and 7), one power relay (230 V / 5 A), one LED indicator on
the panel controllable by program, Dallas bus for connection of access chip/card readers,
thermometers and input/output expanders.
Examples of use:
GSM detector - conveys information about changes of input state via SMS
GSM home alarm - alarm with GSM communicator
GSM remote control - such as opening gates by ringing
Access identification system - using the Dallas chips for registering attendance
Measurement and control of analogue values
The reading of consumption meters and status via SMS / GPRS

5. Design
The GC 055 design is in a plastic box suitable for mounting on a TS 35 DIN-rail. If the GC 055 is
placed in a metal cabinet, the GSM antenna must extend outside the cabinet. The antenna cable
cannot be adjusted. If the length of the antenna is insufficient, order an antenna with a longer cable.

5.3. Front panel
The front panel of GC 055 is equipped with seven LED
indicators. The 'Action' LED is controlled by the
configuration. The 'GSM' LED indicates the GSM status
(Section 7.2).
LED 1-4 indicates state of output - the LED is lit when the
output is active, the output is earthed.
6. Connection of inputs - outputs
6.1. Connection to the upper row of connectors
The top part of GC 055 is equipped with an
SMA type GSM connector. If the GC 055 has
a metal casing, then the GSM antenna should
be outside the enclosed space.
From the Dallas bus it is possible to
simultaneously connect up to 10 input
devices (thermometers, A/D converters,
expanders) and an unlimited number of
readable access chips. It is necessary to
maintain the polarity of the connected device.
Inputs 1-4 are analogue voltage with a
measuring range of 0 to 30V DC maximum.
6.2. Connection to the lower row of connectors
The lower part is equipped with connectors for
connecting a supply voltage in the range
between 12-24V DC.
Outputs in the active state are earthed (log. 0).
The maximum allowable output current is 0.5
A. The auxiliary relay to the output is for
connecting against the (+) terminal of the
power supply. Output 4 may be the same as
GC 075 and fitted with an internal relay. Load
capacity of the relay is 230V / 5 A.
Outputs 1 and 2 can be used as analogue

7. Installation - Configuration
7.1. Installing the SIM card
Before inserting the SIM, disconnect the power to GC 055. Inserting the SIM card into the
device whilst in use is not advised.
Use the notches on the sides of the front panel and a suitable tool (weak screwdriver) to
gently pry open the cover of the front panel. Open the SIM card holder using slight
pressure in the direction of the arrow (open). Place the SIM into the open door of the
holder so that the notch on the SIM matches the recess in the substrate holder. Close the
SIM card holder and secure with gentle pressure in the direction of the arrow (close). The
SIM card must not be locked with a PIN or the account frozen by the provider. It must also
have sufficient credit and possibly with GPRS data services activated.

7.3. Connecting via PC
A mini USB connector located under the front panel cover is used to connect the GC 055
to a PC. Before connecting the GC 055 to a PC, the software - Level Utility - must be
installed on the PC, which can be downloaded from the manufacturer's website
(www.level.systems - "Downloads" section). After connecting the GC 055 to the PC, the
device will be installed on the PC.
7.4. IDE - Control Panel
Level IDE - Control panel is a software tool for configuring the product line GC 05x and GC
07x and allows you to view the current status and download the report. In Basic
parameters you need to select Unit type - GC 055.

Example of configuration - sending SMS with text "Alarm" to phone number 777888999 at
rising edge of pulse on input 1.
8. SMS - editing configuration - control
Via SMS you can't create a new configuration for the device, but only edit the existing
configuration for the device (eg phone number in the phone book). For a list of available
SMS commands, see the software Help Control Panel in the Appendices. Setup and
operation is done through SMS messages sent to the phone number of the SIM card in the
communicator.
The shape of the control SMS:
PASSWORD command1 parameter1 command2 parameter2 command3 parameter3
command4 parameter4
PASSWORD maximum 8 characters a-z and 0-9. Factory setting is ‘picola‘.

One SMS message can contain up to 4 commands with parameters. The communicator
will confirm the execution of commands by sending an SMS. Lower and upper case letters
are only distinguished in the password.
For remote access to GC 055 via GPRS it is necessary to set the APN (Access Point
Name) to connect to the Internet.

After receiving the SMS GC 055 will send UDP packets to the IP address and port. The IP
address must be a fixed and public, routeable port to the PC where the conenction is to be
made. The port must be enabled in the firewall on the PC. In the Control Panel, you need
to wait for connections on the appropriate UDP port. For settings and procedures, see the
software Help IDE - Control Panel.
It is also possible to use the Tunnel - Connection Server from Level for remote access. No
public IP address is required for this connection. Access to this service is available on
request from technical support.
