General INSYS GSM 4.3

4 General

The INSYS GSM 4.3 is available in two versions. These are

 INSYS GSM 4.3
 INSYS GSM 4.3 compact

The INSYS GSM 4.3 differs by a compact design housing for in-wall connection
boxes and the missing audio interface from the INSYS GSM 4.3. Both versions are
referred to as INSYS GSM 4.3 in the further course of this manual. If the INSYS
GSM 4.3 compact differs from the INSYS GSM 4.3, this will be mentioned in par­ticular in the respective sections.

16

INSYS GSM 4.3 Functional Overview

5 Functional Overview

The INSYS GSM 4.3 offers the following functions:

 Data buffer for serial data transmission
The INSYS GSM 4.3 has a fast send and receive buffer (cache) to ad-

just the modem to the operating speed of the application.

 Hardware and software data flow control
The INSYS GSM 4.3 can transmit to the application via the control

lines of the serial interface to interrupt the dataflow, if the buffers of
the INSYS GSM 4.3 exceed a certain level. An application can also
prompt the INSYS GSM 4.3 via a control line to interrupt the data
flow. As an alternative, the INSYS GSM 4.3 can control the data flow
via XOFF/XON characters in the data stream.

 Selective call answer
The INSYS GSM 4.3 can be set to accept only calls from phone num-

bers that were previously stored.

 Configuration via SMS
Numerous functions of the INSYS GSM 4.3 may be configured via

SMS. This allows a configuration of the INSYS GSM 4.3 without PC
and modem connection.

 Comfortable Configuration of the SMS recipients
For each alarm message, which is sent by the INSYS GSM 4.3, up to

10 recipient numbers may be assigned using a matrix. This allows for
the creation of an alarm plan and the targeted notification of service
personnel

 Voice functionality (not INSYS GSM 4.3 compact)
The voice functionality allows to establish voice connections with

other phones using a connected phone receiver. This provides an
easy communication with the service personnel at the site.

 Automatic call acceptance for voice connections
The INSYS GSM 4.3 enables to accept voice calls automatically. This

allows for an automatic voice connection establishment, e.g. for
emergency call or monitoring purposes.

 Remote firmware update
The firmware of the INSYS GSM 4.3 may be updated remotely. The

settings, which are important fort he operation, like the SIM PIN are
maintained with this.

17

Functional Overview INSYS GSM 4.3

 Remote configuration
The INSYS GSM 4.3 can be configured remotely with the help of a

common modem and a terminal program.

 Sending messages via data connection, SMS or Fax
The INSYS GSM 4.3 can send up to 10 previously entered messages

to any defined recipient via an AT command. The dispatch can also be
triggered by switching the alarm inputs. Several transmission paths
are possible, such as Fax and SMS.

 Pulse input to send up to 10 SMS messages
The SMS to a previously defined recipient can be triggered via the

number of pulses at an alarm input.

 IO states retrievable via DTMF and SMS
The state of the inputs and outputs may be retrieved remotely with

the help of DTMF digits sent from a common phone or via an SMS
with an AT command. The INSYS GSM 4.3 answers and replies with
the status of the inputs and outputs via signal tones or SMS.

 Remote switching of the outputs via DTMF and SMS
The switching outputs at the INSYS GSM 4.3 can be set remotely

with the help of DTMF digits sent from a common phone. The alarm
inputs can be selected via a DTMF phone. Furthermore, the output
may be switched via an AT command received by an SMS.

 Switching inputs and alarm outputs for SMS dispatch and to establish

an alarm data connection

The INSYS GSM 4.3 has two potential-free switch outputs, which can

be used to switch other functions in an application. The INSYS GSM

4.3 also has digital switch inputs, which are used to establish connec­tions or to send messages via SMS and fax.

 Switching the output via events like level drop at alarm input, GSM

network failure, incoming call or switching on the device

The INSYS GSM 4.3 can change the state of a switching output in

case of events like GSM network failure, incoming call, switching on
the device or connecting the alarm input to ground. This enables your
application to react on these events.

 Pulse output via switching outputs
The switching outputs can be opened and closed sequentially. This

enables to output so-called „counting pulses“ at the outputs of the
INSYS GSM 4.3. The INSYS GSM 4.3 can output up to ten pulses per
output.

18

INSYS GSM 4.3 Functional Overview

 Access control
The INSYS GSM 4.3 can be protected from unauthorized access via a

phone connection. An incoming connection must first be enabled
with a password. Using security callback, the INSYS GSM 4.3 calls a
previously defined phone number back, when a call comes in.

 Idle connection control with Data Transmit Control
Data Transmit Control enables the INSYS GSM 4.3 to terminate the

connection, if no data is transmitted during a defined state. This will
prevent unnecessary costs.

 Integrated real-time clock
The integrated real-time clock can be used to send alive messages

time-controlled. Furthermore, the integrated real-time clock allows for
a regular logout and login out of or into the GSM network.

 Event history
All occurred events are logged in a history with a maximum capacity

of 200 entries.

New functions of the INSYS GSM 4.3:

 Switching the outputs by establishing a modem connection
The INSYS GSM 4.3 can change the state of a switch output by estab-

lishing a modem connection (enabling of the control line DCD). This
enables your application to react on such events. The output will be
reset to its initial state if the connection is released.

 Switching the outputs via clear text commands
The INSYS GSM 4.3 allows to assign clear text names (switch alias) to

certain switch operations. These clear text names can easily be used
to switch outputs via SMS or AT command.

 Pulsing the outputs via DTMF
The switch outputs at the INSYS GSM 4.3 can also be pulsed re-

motely from a usual telephone by entering DTMF digits now.

 Buffering the alarm inputs
Up to 5 alarm messages are buffered at the inputs and processed

consecutively.

 Reading out SCN from the SIM card
The SMS Service Center Nummer (SCN) can easily be read out from

the SIM card and stored.
