Crestron TPMC-8X-GA Isys

8.4” WiFi Touch Screen
Program Manager
Program Manager is the view where programmers “program” a Crestron control
system by assigning signals to symbols.
The symbol can be viewed by double clicking on the icon or dragging it into Detail
View. Each signal in the symbol is described in the SIMPL Windows help file (F1).
Programming with VisionTools Pro-e
Touch screen pages should be created in Crestron VisionTools
®
(VT Pro-e) to allow
accessing the embedded applications, switching of source signals to desired outputs
as well as selection of the system mode. There are no special programming
requirements to use the functions of the TPMC-8X-GA in a room-control system.
Multi-Mode Objects
Multi-mode objects offer high-
erformance programming!
The single most-advanced VT Pro-e high-performance programming technique
involving the TPMC-8X-GA is the concept of multi-mode objects. A multi-mode
object (i.e., button, legend, etc.) is an object drawn on a VT Pro-e page that can have
one or more active and inactive visible settings (modes).
For examples, refer to www.crestron.com/exampleprograms
and search for multi-
mode object examples. This file contains the VT Pro-e touch screen files and SIMPL
Windows files that illustrate the high-performance capabilities of multi-mode
objects.
WAV File Audio Messages
The TPMC-8X-GA touch screens are capable of playing audio messages as system
prompts and responses. These files are recorded as WAV files on a PC using an
audio utility such as Sound Recorder that is packaged with Microsoft Windows. Files
from other sources may also be converted to an acceptable format by using this or a
similar utility. Many other audio utilities are available commercially or as shareware.
The TPMC-8X-GA touch screens accept the following WAV file formats: PCM, 8
& 16 bit, 8 – 44.1 kHz, mono & stereo. For more information about how to use
Sound Recorder, refer to its User’s Guide and extensive help information provided
with the software. Also, refer to the help file in VT Pro-e to learn how to use its
audio tool, Sound Manager, to attach WAV files to a touch screen project.
Pre-recorded WAV files for voice prompts and responses are available from
Crestron. These files can be stored into and programmed for use in the touch screen
directly or may be edited with the Sound Recorder. For example, the individual files
can be combined to create custom messages.
NOTE: Touch screen WAV files can be obtained from the Wave LC Library of the
Crestron FTP site.
Bit Depth and File Size
A balance of performance and quality can be achieved by using VT Pro-e to
configure the size of graphics in a project. Read this section to learn about bit depth
and how to maximize the quality and performance of a TPMC-8X-GA project.
Bit depth refers to the number of memory bits used to store color data for each pixel
in a raster image. A touch screen raster image consists of a rectangular grid of
picture elements (pixels). Each pixel uses the same amount of memory to store its
color data. The amount of memory is called the bit depth of the image.
Greater bit depths are required to represent finer gradations of color. Increasing bit
depth necessarily increases file size. A black and white drawing requires only one bit
