GP IO outputs
SurroundControl systems can output control signals for acti-
vating alarm indicators or to control external units and applica-
tions. For each Sub Preset (
Key 1
to
Key 7
), a
GP IO output
or a combination of outputs can be selected to be activated
when activating a Sub Preset by pressing the corresponding
button in the Toolbar.
Example
You have to monitor a Dolby® encoded audio signal of
a video/audio data stream. Because of the delays in the
decoding process, it is often necessary to match audio
and video delays for synchronizing video and audio again.
By selecting the Sub Preset containing the settings for
the Dolby® signal source on the SurroundControl, the
according
GP IO outputs
are activated automatically. The
outputs are used to start your external applications and
units controlling the delay for the synchronization of the
video and audio signals.
The state of the 8
GP IO outputs
can be
active low
or
active
high
, the output signal timing can be
permanent
or
momen-
tary
. The assignment of more than one output to a single key
is possible. For example, it is possible to use two outputs to get
four switching states.
Please proceed as follows to use the GP IO outputs for activating external applications or system units:
1. Determine
the
GP IO outputs
to be used as
Key Pre-
sets
or for
Alarm
function.
2. Disconnect the unit from the power supply.
3. Use a counter plug to connect the
GP IO
connector of
the units to the external applications to be controlled or to
receive the alarm signal. Connect one lead of the transmit-
ting cable to your application with the pin on the counter
plug corresponding to the
GP IO output
you want to use.
Connect the other lead to pin 25 for common potential.
4. Correspondingly, connect the cable to your application
and units.
5. After wiring all determined connections, connect the
counter plug to the
GP IO
connector of the SurroundCon-
trol unit.
6. Connect the unit to power supply and power it on.
7. Press
the
MENU
button. The menu system is initialized.
8. Use
the
<
or
>
button to select the
GPIO Confi gurati-
on
menu tab. The
Global GPIO Settings
menu page is
displayed.
9. Use
or
button to set the focus to the
Function
com-
bo boxes of the
Outputs
you have to change. Confi rm
with
red Sel
(SELECT) key.
10. Use
or
button to set the focus on the function option
you need (
Key Preset
or
Alarm
). Enter the selection by
pressing the
red Sel
(SELECT) key.
11. Repeat steps 7 and 8 for the other output functions you
have to change.
12. Use
or
buttons/keys to select the
Output Signal Ti-
ming
combo boxes and the
Output Logic
combo boxes.
Confi rm by pressing the
red Sel
(SELECT) key. Proceed
as described in steps 7 to 9.
