GCxxxLink–User and installation guide 5
Page S.03 (GC315Link) or S.04 (GC400Link) shows:
➢the active connection type GSM, EDGE, LTE NB-IoT or LTE CAT-
M1.
➢the Mobile Network Operator (MNO) currently connected
(Vodafone, TIM….). If the SIM card does not return the full name
the Mobile Country Code (MCC) + Mobile Network Code (MNC)
is shown.
➢the mobile network signal intensity.
To use the Global Navigation Satellite System (GNSS) internal receiver, using GPS, GLONASS, GALILEO
or BeiDou system, the internal module has to be enabled with the parameter P.0580 (GPS module enable).
Connect also the GNSS antenna. The purpose of this module is to detect the controller position
(latitude/longitude). Once detected, the position coordinates can be asked via SMS* and it can be used to
pinpoint the genset on a map (many business sites allow this operation).
The position becomes most important in the use with “Si.Mo.Ne.” system. Directly from the WEB interface it is
possible to display the position of a genset on a map, and it is also possible to display the tracking of a rented
genset in a period of time: both these functions are useful for rented gensets, but can also be used as antitheft
system. If you use the GNSS module, it is possible to configure the controller to send messages to “Si.Mo.Ne.”
server if any movement is detected:
•P.0583: configures the minimum movement (in meters), beyond which the controller sends a message
to “Si.Mo.Ne.” server.
•P.0584: configures a minimum interval for the issue of position messages to “Si.Mo.Ne.” server (at most
the controller sends a message in the configured interval).
The controller displays the GNSS coordinates on page S.04 (GC315Link) or S.05 (GC400Link ).
The coordinates flash if the GNSSmodule is not able in that moment to determine the position (therefore the
last position detected is shown). It also shows the HDOP value: it is a
precision indicator (the lower it is, the sharper the position). Finally, it the
number of used satellites in every instant.
If there is no need of automatic localization or Tracking, it is possible to
disable the module and it is still possible to manually set the latitude
(P.0581) and longitude (P.0582) of the generator set.
GSM/LTE antenna (700-960/1710-2655 MHZ) must be connected to the LTE SMA plug on the Link device;
use only omnidirectional antennas. The maximum gain allowed to antenna and its cable is 3 dB. The
impedance of the antenna must be 50 ohm. It is not allowed to connect the antenna directly on the plug but a
minimum of 3 m of proper coaxial cable is required.
GPS antenna or GPS+GLONASS antenna must be connected to the GNSS SMA plug on the link device. Use
only active antennas with impedance of 50 ohm. The plug of the Link device provides automatically the power
supply required (Max 35mA@3,3Vdc).
It is possible to use a combined antenna GSM/LTE+GPS/GLONASS or GSM/LTE+GPS antennas. Both
integrating GPS/GLONASS and GSM/LTE antennas in just one body; they can be provided on request
together with the Link devices.
