Activate Querying of the Inputs via DTMF
The inputs at the INSYS GSM 4.3 I4 can be queried via the DTMF tones of a conventional
telephone. The input states will be transformed acoustically into tone sequences of well
differentiated high and low tones.
Configuration with HSComm
In order to
enable the DTMF function
, activate on the “Basic Settings” tab on
the “GSM Connection” panel the check box “DTMF processing”.
After changing the DTMF settings, a reset must be performed that the
changes become effective. For this, clock on the “Reset” button in the field on
the right.
Configuration with AT commands
In order to
enable DTMF mode
, use the com-
mand
AT**DTMF=1
In order to
disable DTMF mode
, use the com-
mand
AT**DTMF=0
In order to
query the state of this function
, use
the command
AT**DTMF?
After changing the DTMF mode, the INSYS
GSM 4.3 I4
must be reset
that the changes
become effective. For this, use the command
AT**RESET
If the DTMF processing is enabled, automatic call acceptance does not have
to be enabled explicitly, because the INSYS GSM 4.3 I4 accepts voice calls
automatically in any case.
Querying the inputs via DTMF can be protected with the optional DTMF PIN. The DTMF
PIN protects the access for switching and querying the inputs/outputs via DTMF tones
during a voice connection. The DTMF PIN consists of 4 digits.
The DTMF PIN must not be mixed up with the PIN of the SIM card. These
are two independent PINs.
Configuration with HSComm
In order to
enable the DTMF PIN,
click on the “Access Control” tab on the
“Password for” panel on the “set PIN” button under “output control by DTMF”.
Enter the PIN into the “new PIN:” field and again into the “confirm PIN:” field
and click the “OK” button.
In order to
change the DTMF PIN
, click on the “Access Control” tab on the
“Password for” panel on the “set PIN” button under “output control by DTMF”.
Enter the old PIN into the “old PIN:” field and the new PIN into the “new PIN:”
field and again into the “confirm PIN:” field and click the “OK” button. If you
do not enter a new PIN, the DTMF PIN will be disabled.
