Crestron QM-FTCC-TPS4 FlipTop Touchpanel Computer Center
The completed and compiled project is uploaded to the touchpanel and programmed
into the flash PROM via the
File | Upload Project
command. The touchpanel uses
the programmed project until another set is uploaded from the PC. The PC may be
disconnected from the control system or panel except during reprogramming.
When you start the VT Pro-e project for this product, select QM-FTCC-TPS4 as the
panel type.
For additional software information, refer to the help file provided with the software.
The latest version of VT Pro-e can be obtained from the Crestron website.
Adjusting the QM-FTCC-TPS4 Microphone Inputs
Once a QM-FTCC-TPS4 is installed and configured, settings for gain, gating level,
attack time, and decay time should be set using the SystemBuilder finish tab.
NOTE:
Crestron recommends that you use the latest software to take advantage of
the most recently released features. The latest software is available from the Crestron
website.
Definitions
The QM-FTCC-TPS4 allows for adjustments to be made to microphone input
signals. The following are definitions of terms that are commonly used when making
adjustments.
Attack Time
The time it takes (in milliseconds) from when an input signal rises above the gating
level until the microphone output signal is enabled.
Clipping
A condition in which a signal level exceeds the maximum level (the clipping level) a
circuit can handle. This is usually caused by improper gating parameters and gain
settings.
Decay Time
The time (in milliseconds) from when an input signal falls below the gating level
until the microphone output signal is muted.
Gain
An adjustable amplification to accommodate varying input signal levels.
Gating
Gating is a function that mutes a microphone signal when the input sound level is
below a user-set threshold (gating level).
The following diagram demonstrates clipping, attack time, decay time, and gating
level.
