The GD-04K universal GSM
communicator and controller
The GD-04K is a universal GSM communicator. It controls and / or reports status of
different appliances remotely. Control can be performed by SMS instructions or dialling in.
The module is equipped with 2 power outputs with a status or pulse reaction. For status
monitoring the GD-04K module has four input terminals which react to grounding
(connecting to the GND terminal). Activation / deactivation of an input terminal can be
reported as an SMS, dialling in or a combination of both these options to up to 100
authorised telephone numbers. The GD-04K can also be supplemented by a GD-04A
backup battery which ensures powering the module when the mains is disconnected. The
module allows configuration using a PC with installed GD-Link 2.0.0 software (or higher)
locally via the USB cable or remotely. It can also be configured by programming SMS.
1.
Using the GD-04K
The GD-04K module uses four inputs (A – D) for SMS reporting (optionally dialling) to
predefined telephone numbers. It also offers 2 power relay outputs with options to control
them by pre-defined SMS commands or by dialling in according to the settings from
authorised numbers or from any (non-authorised) numbers.
Relay control:
by SMS instructions which can be independently pre-set for switching ON / OFF of
each relay output. Both relays can work in status or pulse mode, the mode is selectable
in the settings. If pulse mode is selected then based on activation command the output
will be switched for interval between 1 s to 10 hrs.
Dialling in. Both relays (X and Y) can be controlled by dialling in from a known
telephone number. Up to 100 numbers can be stored in the communicator. The GD-
04K doesn´t pick up an incoming call but verifies the caller's telephone number. If the
caller's telephone number is authorised, the call is rejected and the relay is activated /
deactivated as required (when the Impulse reaction is set then for predefined time).
Dialling in with limited use. While entering authorised telephone numbers the limit of
their use can also be defined for each of them. When the usage limit of a pre-defined
number is reached then any other calls are ignored. Reactivation can only be allowed
by an administrator (by SMS). This function is suitable as a subscription for entrance to
garages and so on.
Input status reporting:
Sending an SMS report when some of the inputs (A – D) are activated / deactivated
(connected or disconnected to / from GND). Each input has an option to edit the texts
which are reported. An SMS can be sent to all telephone numbers stored in the
communicator. For higher alert notice SMS report can also be followed by calling to the
numbers to which SMS reports have been sent.
Status monitoring. By the SMS command "STATUS", the status of all inputs and
outputs can be checked when needed. This way is for example possible to check status
of connected devices which each status change is not required to report.
Caution: The GD-04K is not meant and is not certified as a security device to protect
premises.
