7.8 SETTINGS SECTION
This section displays all the technical and working parameters related to features such as:
DTMF Generator, DTMF Decoder, General Purpose I/O and Delay. Specifically, DTMF Generator is defined as all the
controls for the generation part of DTMF tones to be sent to the Analog and Digital output. DTMF Decoder instead refers
to the checks for the recognition of DTMF tones received on a particular input. The General Purpose I/O section defines
the procedures for operation both of the General Purpose Input and General Purpose Output. The Delay section
concerns the possibility for Fox to introduce a delay line on a particular input or a given output in order to keep different
sources aligned with arrivals offset against each other.
7.8.1 DTMF Generator section
The “
Cmd by GP Input
" checkbox indicates the Fox option of accepting and thus encoding DTMF commands by closure
of the various GPIn. An example as shown in the photo, if it is included in the section
General Purpose I/O
to section
GP Inp 1
, the
DTMF CMD3
section, when Input 1 goes to 1 (i.e., is activated) then on the analog and digital output the
DTMF command corresponding to the
CmdString #3
will start. As stated, all this is subject to the "
Cmd by GP Input
"
checkbox that if enabled makes the actions described above operational.
The "
Mixed Mode
" checkbox indicates that Fox is able to mix, mix the audio DTMF commands that it was previously
managing in input. In doing so, it is also possible to add the DTMF commands to the Fox audio input. Where you don't
wish to add the DTMF commands to the audio from the Fox input, simply de-select this checkbox. In this case however
the sound is first stopped, then the DTMF commands are sent and subsequently upon sending of the strings the audio
returns in output.
"
Analog Out Level"
and “Dig.Outlevel”
mean the level at which the DTMF tones are issued on the respective Analog
and Digital audio outputs. The recommended level is -10 dB in a situation of mixed audio. The Fox machine is able to
operate up to a minimum of -30 dB, but the conditions required to obtain these levels are by using the "
Speed Slow
" and
activating on Fox the '
Decode Low Levels
" checkbox located in reception.
In the section "
DTMF Speed'
it is possible to select the speed at which the DTMF strings are transmitted. As is known:
more robust operation is obtained by using the Slow commands and the DecodeLowLevels disabled.
The "
Test Command" section instead
serves to manually run a Test command to the Analog or Digital outputs. It is
possible to select one of the four DTMF commands.
