Wall Mount 2-Way RF Compact
Color Touchpanel: STX-1550CW

Description

Functional Description

The STX-1550CW is a 2-way radio frequency (RF) compact color SmarTouch

touchpanel that, when used with the BB-1550CW back box and DA-1550CW

docking assembly, is wall mounted and provides a user interface to a Crestron

remote control system (herein referred to as the Cresnet system). While the

touchpanel is docked, the DA-1550CW provides operating power, hard-wire

communications with standard Crestron remote control system (herein referred to as

the Cresnet system), and recharges the Crestron High Performance Rechargeable

Power Pack (ST-BTP) of the touchpanel.

The STX-1550CW touchpanel offers:

• 256 color display

• pop-up subpages to reduce memory requirements, providing optimal

speed and performance

• multiple button and icon configurations

• up to 999 functions and 96 screens

• imported photographs, drawings, and icons

• support for downloadable fonts, proportional and non-proportional

• foreign language text

When not docked in the DA-1550CW, the touchpanel is a handheld, long range, RF,

2-way wireless transceiver that communicates through a RF transceiver/gateway,

STRFGWX (sold separately) to the Cresnet system. The 2-way communications

provide delivery of commands to the Cresnet system and provide dynamic onscreen

feedback for real-time confirmation of commands. Up to 15 touchpanels can

communicate with one STRFGWX. The RF signals can travel from a minimum of

three feet up to a maximum of 150 feet. The location of the STRFGWX and the

orientation of the antenna are important factors in the RF performance.

At the underside of the unit is a docking plate and the power pack/battery

compartment that holds one ST-BTP. Electrical contacts for the DA-1550CW are

through the underside of the unit. There are also four rubber feet on the underside for

stability and to prevent slippage.

Software

The STX-1550CW is supported by the VisionTools™ Pro-e (VT Pro-e) SmarTouch

Wizard that automatically configures the entire system and the touchpanel pages. VT

Pro-e, a design and programming Windows®-based software, permits the creation of

unlimited control screen variations incorporating two and three-dimensional graphics

and text. A set of pages which make up a project can be designed for each

touchpanel application. Each page contains objects such as custom control graphics,

two and three-dimensional buttons, sliders, and digital readouts which allow the user

to interface with the Cresnet system. The project is uploaded to the touchpanel and

programmed into the flash PROM. The touchpanel uses the programmed project

until another set is uploaded from the PC. The PC may be disconnected from the

rack or panel except during reprogramming. VT Pro-e also allows users the option to

generate projects destined for web browsers rather than for physical touchpanels.

For additional software information, refer to the help file provided with the software.

A copy of the software can be obtained from the Downloads page (TOUCHPNL

Library) of Crestron’s website (www.crestron.com). New users are required to

register in order to obtain access to the FTP site. A tutorial is provided as a guide for

the novice programmer.

General Use and Safety

WARNING: To avoid shock hazard and possible damage to the unit, do not use
touchpanel in rain or expose it to unnecessary moisture.

Recommended Touchpanel Cleaning

Keep the surface of the touchscreen free of dirt, dust, or other materials that could
degrade optical properties. Long term contact with abrasive materials can scratch the
surface which may detrimentally affect image quality.

For best cleaning results, use a clean, damp, non-abrasive cloth with any
commercially available non-ammonia glass cleaner. Surrounding plastic enclosure
may not provide a complete water-tight seal. Therefore, apply cleaning solution to
the cloth rather than the surface of the touchscreen. Wipe touchscreen clean and
avoid ingress of moisture beneath panels.

Applying Power

The touchpanel can be powered via the DA-1550CW while docked, the ST-BTP, or
external AC power pack. Each of these items has their own Operations Guides which
details proper usage. Refer to the table on the next page for the required document.

Identity Codes

The STX-1550CW touchpanel uses three distinct types of identity (ID) codes:
Cresnet identity (NET ID), RF ID, and RF CHANNEL. These codes are assigned to
the touchpanel from the Interface Submenu when the unit is configured. Refer to
“Interface Submenu” on page 7. For the touchpanel to be identified within the
Cresnet system, these assignments must match assignments made in the SIMPL
Windows program. The RF CHANNEL assignment made for the STRFGWX is
made in the Crestron Viewport via SIMPL Windows or VT Pro-e. Refer to
“Programming in SIMPL Windows” on page 9.

NET ID

Every equipment and user interface within the Cresnet system requires a unique NET
ID. These codes are recognized by a two-digit hexadecimal number from 03 to FE.
The NET ID of the unit must match the NET ID specified in the SIMPL Windows
program.

RF ID

Every STX-1550CW touchpanel communicating with a STRFGWX requires a
unique RF ID to secure RF communications. There are 15 useable codes for multiple
touchpanel(s) ranging from 1 to F (hexadecimal number). The RF ID of the unit must
match the RF ID specified in the SIMPL Windows program.

RF CHANNEL

Each STX-1550CW touchpanel communicating to the network via a specific
STRFGWX transceiver must have a RF CHANNEL that matches the RF CHANNEL
of the STRFGWX. Each STRFGWX in a system requires a unique RF CHANNEL.
There are 16 possible RF CHANNELS ranging from 0 to F (hexadecimal number).
The RF CHANNEL of the unit must match the RF CHANNEL assigned to the
STRFGWX via the Viewport in SIMPL Windows or VT Pro-e.

Configuring the Touchpanel

To configure the touchpanel, it is necessary to access a series of setup screens prior
to viewing run-time screens that are loaded into the touchpanel for normal operation.
The Main Menu for configuring the touchpanel appears when a finger is held to the
touchscreen as power is applied. Remove your finger when the message “SETUP
MODE” appears on the touchscreen. Holding a finger to the touchscreen for five
seconds after the “SETUP MODE” message is displayed sets the brightness to high.

Manage Power Submenu

Manage Power Submenu

NOTE: Display backlight requires warm-up time. A display reaches 80% of its
final level in five minutes and full brightness in 20 minutes.

The touchpanel display hardware life can be lengthened by turning off the backlight
when the touchpanel is inactive. The MANAGE POWER button on the Setup
Menu reveals the Manage Power Submenu, shown to the left. The length of
touchpanel inactivity can be specified to minimize power utilization.

BACKLIGHT TIMEOUT is displayed on the Manage Power Submenu. This
setting turns the backlight off when the touchpanel is inactive for the specified time
(shown in minutes). When the touchpanel is activated, the last screen to be displayed
reappears. A two minute BACKLIGHT TIMEOUT is shown in the diagram.
Minutes can vary from 0 to 120, where 0 disables the timeout. The DOWN and UP
buttons decrease and increase the timeout, respectively.

NOTE: Power Down Timeout should be set low to maximize power pack/battery
life. However, Power Down Timeout should be set greater than Backlight Timeout.
Otherwise, the Backlight Timeout is never reached.

Interface Submenu

NOTE: The purpose of the Power Down Timeout is to maximize power
pack/battery life. If the touchpanel is docked in the DA-1550CW docking assembly
or utilizes an external AC power pack, the panel does not power down when the
power down timeout is achieved. Standby timeout still functions.

Touch the RETURN button, located in the bottom right corner of the screen, to
display the Setup Menu.

Interface Submenu

The touchpanel communicates with a Cresnet system to activate other controls or to
display feedback from components within the system. The communication interface
must be correctly specified or communication will not occur. To set communication
parameters select the INTERFACE button from the Setup Menu to display the
Interface Submenu, shown to the left.

The NET ID is represented by ID # # for illustrative purposes on the Interface
Submenu. NET ID is the two-digit hexadecimal number that can range from 03 to FE
and must correspond to the NET ID set in the Crestron Viewport via SIMPL
Windows or VT Pro-e software. Matching NET IDs between the STX-1550CW
touchpanel and a VT Pro-e program is required if new touchpanel screens are to be
loaded. Matching NET IDs between touchpanels and a SIMPL Windows program is
required if data is to be successfully transferred. The NET ID of each STX-1550CW
is factory set to 03.

Two side-by-side buttons, < CRESNET ID and CRESNET > ID, decrease and
increase the NET ID by one, respectively.

Operations Guide - DOC. 5849 Wall Mount 2-Way RF Compact Color Touchpanel: STX-1550CW •• 7

The touchpanel usually communicates with a Cresnet system. Occasionally the
touchpanel can be used in a local demo mode where it merely displays various
menus, but does not communicate with the Cresnet system. In local mode, the
directory buttons change pages, but buttons requiring feedback do not work. Two
buttons on the Interface Submenu, CRESNET II and LOCAL, determine
communication mode. Select CRESNET II for the normal Cresnet communication
mode and LOCAL to set the touchpanel into demo mode. Text within the selected
button changes color from black to red and the communication mode is factory set to
CRESNET II.

RF Settings Screen

The RF SETTINGS button opens the RF SETTINGS screen, shown to the left. The
RF ID is displayed in the RF SETTINGS screen. The RF ID must match the identity

code in the SIMPL Windows program and is identified by a hexadecimal number in
the range from 0 to F. In the diagram, the RF ID is shown with a setting of “1”. The
DOWN and UP buttons associated with the RF ID field decrease and increase the RF
ID by one, respectively.

The RF CHANNEL of the touchpanel
must be identical to the RF CHANNEL
of the STRFGWX to which it
communicates.

Sound Submenu

The RF CHANNEL is displayed in the RF SETTINGS screen. The RF CHANNEL
is identified by a hexadecimal number in the range from 0 to F. In the diagram, the
RF CHANNEL is shown with a setting of “0”. The DOWN and UP buttons
associated with the RF ID field decrease and increase the RF ID by one,
respectively.

The TEST button should only be used under supervision from a Crestron customer
service representative during telephone support. The options available from the
TEST Menu are beyond the scope of this guide.

Select the RETURN button after interface parameters have been set.

Sound Submenu

The SOUND button, located at the top right corner of the Setup Menu, is used to
display the Sound Menu, shown to the left. Use this screen to activate audible key
clicks. This feature is a useful feedback tool. Confirmation of a button press on a
touchpanel is acknowledged by an audible click assuming this feature is enabled. To
enable this feature, verify that the KEYCLICK ON button is active (red). An active
KEYCLICK OFF button disables the feature. Volume of the audible click is
controlled with the VOLUME UP and VOLUME DOWN buttons. The unit is
factory set with the sound on.

Contrast Buttons

Screen contrast may need to be altered because of ambient light conditions, panel
temperature, or personal preference. Two contrast buttons, CONT << and
CONT >>, on the Setup Menu may be held down for continuous adjustment of the
screen.

Appendix

The purpose of this Appendix is to provide a programming solution for those that
prefer the last screen to be displayed when the touchpanel turns on after encountering
a POWER DOWN TIMEOUT. Stated simply, an INTERLOCK symbol needs to be
incorporated so that the control system flips to the last page rather than the page
marked as first. The information in this Appendix is not meant for everyone; only
those who wish to adopt this feature.

Overview

This Appendix offers a simple example of a control system that has three devices to
control: TV, VCR, and projector. As such, the VT Pro-e project includes three pages,
one for each device. Particular settings must be made on each device page to ensure
proper functionality. To support the goal of having the last page appear, the program
needs to be adjusted via SIMPL Windows. This Appendix provides a SIMPL block
diagram and description to characterize the details of the adjustment.

VT Pro-e Project

NOTE: The control logic for these devices is omitted for the sake of clarity.

NOTE: It is assumed that the reader has a working knowledge of VT Pro-e. If any

of the terms in this discussion are unfamiliar, please review VT Pro-e’s on-line help
contents.

The VT Pro-e project in this example contains three device pages: TV, VCR, and
PROJECTOR, shown below.

Three Device Pages in the VT Pro-e Project

Operations Guide - DOC. 5849 Wall Mount 2-Way RF Compact Color Touchpanel: STX-1550CW •• 15

Wall Mount 2-Way RF Compact Color Touchpanel Crestron STX-1550CW

Button Assignment

In this system, the buttons labeled Press Here for VCR Control on the TV and
PROJECTOR pages are assigned a page flip to the VCR page and command the
projector to switch to its first video input. The buttons labeled Press Here for TV
Control on the VCR and PROJECTOR pages are assigned a page flip to the TV
page and command the projector to switch to its second video input. The buttons
labeled Press Here for Projector Control on the TV and VCR pages are assigned a
page flip to the PROJECTOR page. No other action is assigned.

All buttons on the device pages that cause page flips must be joined. This setting
permits the control system to keep track of every page flip and determine which page
is currently being displayed. That information is useful if the last page to be
displayed appears after a POWER DOWN TIMEOUT.

Join Number Assignment

In this example, Press Here for TV Control (Join # 6) and Press Here for VCR
Control (Join # 9) already have joined numbers assigned because they perform a

function. Only Press Here for Projector Control requires a new join number
assignment (Join # 22).

Each device page that is a destination of a page flip must be assigned a join number.
For this example, the page join numbers shown in the table below are assigned to the
device pages.

Page Join Number Assignments

DEVICE PAGE NAME PAGE JOIN NUMBER

PROJECTOR 23

VCR 24

TV 25

SIMPL Program

In the SIMPL program, a signal must be assigned to Join # 22, so that the system
knows when a page is flipped to the PROJECTOR page. The name PROJ-FLIP is
assigned and placed on the button press side. There is no reason to have feedback on
the button since it flips the page immediately. For this example, assume Join # 6 is
assigned the signal name of TV-FLIP and Join # 9 has the signal name of VCR-FLIP.
Refer to the block diagram shown below.

These three signal names should drive an INTERLOCK symbol so that the system
can “remember” which page was shown last on the touchpanel. The outputs of the
INTERLOCK are assigned unique names: TV-FLIP-F, VCR-FLIP-F, and
PROJ-FLIP-F.

Finally, the corresponding feedback signals from the INTERLOCK must match the
appropriate page join number. For this example, the page join numbers shown in the
table below correlate to the INTERLOCK output signals.

Conclusion: How the Example Works

NOTE: Since the control system is controlling the page flips on the touchpanel, the
page flip setting on the buttons shown on the device pages can be removed via VT
Pro-e.

To illustrate how the example works, consider the following actions taken by the
user operating a STX touchpanel.

1. While viewing the TV page of the VT Pro-e project on the touchpanel,

the user touches the Press Here for Projector Control button.

2. Join # 22 feedback is activated which forces PROJ-FLIP to logic “1”.

3. The INTERLOCK symbol outputs PROJ-FLIP-F as logic “1”; all other

outputs from the symbol are logic “0”.

4. Join # 23 feedback is activated which forces the touchpanel to flip to

the PROJECTOR page of the project.

5. Let the POWER DOWN TIMEOUT period expire so that the

touchpanel turns off (or turn off the unit) while the PROJECTOR page
is displayed.

6. When the touchpanel is reactivated, the control system provides the

current state of all the analog and digital feedback signals. A logic “1”
for Join # 23 is one of the signals resynced and therefore, the
touchpanel flips to the PROJECTOR page rather than the page marked
as first.
