Interface: TPS-GA-TPI
Introduction
Features and Functions
• High-performance touchpanel interface
• 24-Bit Isys®graphics
• Synapse image rendering algorithm
• Dual window HD video and RGB display
• Built in real time annotation
• High speed Ethernet and Cresnet®communications
• Single space rack mountable
The TPS-GA-TPI is designed to allow for the integration of non-Crestron
touchscreens into the Crestron control system. The TPS-GA-TPI transforms a third
party display device into a full-featured Isys®G-Series touchpanel, producing
stunning control graphics with dual window display of HD video and high res RGB
signals. It is perfect for use with any plasma display equipped with a touch-sensitive
overlay, as well as a variety of LCD touchscreen monitors and interactive pen
displays.
Versatile Touchpanel Interface
To serve a wide range of touchpanel applications from multimedia presentation to
interactive kiosks, the TPS-GA-TPI works with numerous touchscreen and pen
display products from 3M/Microtouch®, SMART Technologies®, Wacom®and many
others. Alternately, its output can be displayed on any high resolution monitor or
large screen projector, providing a graphical interface that is fully navigable using an
onscreen mouse driven cursor. Even without a touchscreen or mouse attached, the
TPS-GA-TPI makes an exceptional high resolution graphics/display generator
perfect for voting systems, command centers, public information and more.
Isys®
The TPS-GA-TPI offers vibrant 24-bit color depth with 8-bit alpha channel
transparency to produce incredible 3D graphics and high res images. The Isys engine
Operations Guide – DOC. 6609A Isys®G-Series Touchpanel Interface: TPS-GA-TPI •1

Isys®G-Series Touchpanel Interface Crestron TPS-GA-TPI
supports dynamic graphics and text, full-motion animations, multimode objects and
PNG translucency - all with astonishing speed.
Synapse™
Crestron's exclusive Synapse Image Rendering Algorithm enables system
programmers to produce amazing graphics - faster and easier. Advanced antialiasing
delivers crisper, sharper objects and text. Enhanced 3D effects add new depth and
style. And because Synapse is native to the touchpanel, memory requirements and
upload time are substantially reduced.
Dual Window HD Video and RGB
The TPS-GA-TPI can simultaneously display two fully scalable, full motion video
windows, each supporting standard video, HDTV and high-resolution RGB signals
from external AV and computer sources. Discrete video scalers with motion adaptive
deinterlacing bring out the highest detail, minimizing visible scan lines and motion
artifacts for a truly remarkable picture. Advanced gamma correction and built in time
base correction ensure accurate color reproduction and a jitter free image.
Touch-the-PC
Crestron's exclusive "Touch-the-PC" technology allows real time touchpanel
navigation of any Windows®PC through a direct high speed serial connection.
Built in Annotation
Built in annotation capability allows presenters to write or draw over computer and
video images on the touchscreen using a finger or stylus and output the image live
for audience display.
Audio Features
An audio output is provided for connection to the display device or separate
amplified speakers, supporting customizable button feedback, personalized sounds
and voice prompts.
QuickMedia™ Output
A QuickMedia (QM) output port is included, allowing for output of the touchscreen
image to feed a remote display device. QuickMedia provides a single cable solution
for routing the TPS-GA-TPI's display output and audio signals up to 450 feet.
High-Speed Connectivity
Both Cresnet and high-speed Ethernet are standard on the TPS-GA-TPI, providing
for easy network integration and seamless communications with Crestron control
systems.

Isys®G-Series Touchpanel Interface Crestron TPS-GA-TPI
Setup
Network Wiring
When wiring the network, consider the following:
• Use Crestron Certified Wire.
• Use Crestron power supplies for Crestron equipment.
• Provide sufficient power to the system.
CAUTION: Insufficient power can lead to unpredictable results or damage
to the equipment. Please use the Crestron Power Calculator to help calculate
how much power is needed for the system (www.crestron.com/calculators).
• For larger networks, use a Cresnet Hub/Repeater (CNXHUB) to maintain
signal quality.
For more details, refer to “Check Network Wiring” on page 46.
Ethernet
The TPS-GA-TPI also uses high-speed Ethernet for communications between the
device and a control system, computer, digital media server and other IP-based
devices.
For information on connecting Ethernet devices in a Crestron system, refer to the
latest version of the Crestron e-ControlReference Guide (Doc. 6052), which is
available for download from the Crestron website (www.crestron.com/manuals).
QuickMedia Wiring
The Crestron QuickMedia cable (sold under the name “CresCAT-QM”) contains one
CAT5E cable and one Cresnet cable in Siamese jackets. Installation of any QM
device is as simple as installing CresCAT-QM wires from the output of one device to
the input of another. Installations are flexible, affordable and fast. For more
information, refer to the latest revision of the Crestron MediaManager Applications
Guide (Doc. 6244), which is available for download from the Crestron website.

Crestron TPS-GA-TPI Isys®G-Series Touchpanel Interface
CresCAT-QM Cable
CresCAT-QM
Cable
NOTE: Do not untwist the two wires in a single pair for more than 1/3-1/2”
(0.84-1.27 cm) when making a connection. The twists are critical to canceling out
interference between the wires.
The aggregate cable length of a signal path originating at the TPS-GA-TPI and
terminating at QM endpoint such as a TPS-12G/15G-QM-L must not exceed 450
feet (137 meters). Video signals may experience a loss of quality over very long
lengths of cable. This phenomenon is due to the added resistance and capacitance of
longer cable lengths and is not peculiar to either Crestron and/or QuickMedia
systems. To ensure sufficient bandwidth, the maximum aggregate cable length
should not exceed 450 feet. The use of lower-resolution signals may allow increased
cable length but must be tested by the installer with the sources to be used. The QM
pin assignment is based on the EIA/TIA 568B RJ-45 Jack standard.
NOTE: When transmitting S-video, luminance uses the green video pathway and
chrominance uses the red video pathway. When transmitting composite video, the
signal is carried on the blue video pathway.
NOTE: When using CresCAT-QM wiring, four additional wires are included for
making Cresnet connections.
When connecting multiple QM devices, the route between a QM origination point
(transmitter) and a QM endpoint (receiver) cannot have more than two midpoints
(e.g. QM-MD7x2 or other QM switchers). Refer to the diagram on the following
page when configuring a QM network.
NOTE: The aggregate length from transmitter to receiver cannot have a delay skew
or more than 22 ns.

Identity Code
Net ID The Net ID of the TPS-GA-TPI has been factory set to 03. The Net IDs of multiple
TPS-GA-TPI devices in the same system must be unique. Net IDs are changed from
a personal computer (PC) via the Crestron Toolbox™ (refer to “Establishing
Communication” on page 42).
When setting the Net ID, consider the following:
• The Net ID of each unit must match an ID code specified in the SIMPL™
Windows®program.
• Each network device must have a unique Net ID.
For more details, refer to the Crestron Toolbox help file.
IP ID The IP ID is set within the TPS-GA-TPI’s table using Crestron Toolbox. For
information on setting an IP table, refer to the Crestron Toolbox help file. The IP IDs
of multiple TPS-GA-TPI devices in the same system must be unique.
When setting the IP ID, consider the following:
• The IP ID of each unit must match an IP ID specified in the SIMPL
Windows program.
• Each device using IP to communicate with a control system must have a
unique IP ID.
Configuring the Touchpanel Interface
NOTE: In order to configure the TPS-GA-TPI interface, power (supplied via
Cresnet) and a connection to an external touchpanel or other video device are
required. Refer to “Hardware Hookup” on page 31 for details.
To configure the unit, it may be necessary to access a series of setup screens prior to
