Two-Way RF Transceiver:
TPS-RFGWX

Introduction

Functions and Features

The TPS-RFGWX is a two-way radio frequency (RF) gateway/transceiver that

utilizes 2.4 GHz spread spectrum technology to communicate with Crestron Isys

tilt touchpanels equipped with the optional TPS-XTXRF Two-Way RF Transceiver

Module, and other similarly equipped Crestron touchpanels such as the STX-

1700CXP.

TM

NOTE: Throughout this operations guide, an Isys

the optional TPS-XTXRF Two-Way RF Transceiver Module is referred to as

TPS-XTXRF equipped touchpanel or touchpanel, except where noted. For related

information, consult the TPS-XTXRF Operations & Installation Guide (DOC. 5844).

Similarly, the STX-1700CXP 2-Way RF Wireless Touchpanel is also referred to as

touchpanel. For related information, consult its operations guide (DOC. 6144). The

latest versions of the guides can be obtained from the Downloads | Product Manuals

section of the Crestron website (www.crestron.com)

The TPS-RFGWX receives RF signals from one or more touchpanels (sold

separately) and translates the signals into commands for transmission over the

Crestron control system (Cresnet system). Feedback signals from the Cresnet system

are transmitted from the TPS-RFGWX to the touchpanel(s) for real-time

confirmation of commands. Up to 15 touchpanels can communicate with one TPS-

RFGWX and, if more touchpanels are needed, more TPS-RFGWXs (up to 16) may

be added to the system.

• Communicates with up to 15 touchpanels

• “Wi-Fi” friendly operating frequency selection to avoid interference

Two-Way RF Transceiver Crestron TPS-RFGWX

The TPS-RFGWX gateway utilizes spread spectrum technology. Spread spectrum

eliminates the risk of signal “drop-out” by automatically cycling through several

frequencies. The RF signals can travel from a minimum of three feet up to a

maximum between 100 - 200 feet indoors; the range is dependent on construction of

the building, obstructions, and RF interference from other devices. The location of

the TPS-RFGWX and the orientation of the antenna are also important factors in the

RF performance.

When an STX-1700CXP or TPS-XTXRF-equipped touchpanel is powered up, it

rapidly scans the assigned frequency band for the synchronizing signal. The

touchpanel may have to scan 75 different frequencies and take several seconds to

synchronize with the TPS-RFGWX. Once the touchpanel is synchronized, it requests

registration from the TPS-RFGWX and is then ready to operate. Typical power-up

time for the touchpanel to establish communication with the TPS-RFGWX is three to

five seconds. However, it may take up to 20 seconds depending on the environment

and radio traffic in the 2.4 GHz spectrum. As more touchpanels are added to the

system, the time required to synchronize and communicate data is extended.

If the touchpanel loses communication with the TPS-RFGWX (i.e., out of range,

battery depleted), the gateway does not store button presses or commands. When the

TPS-RFGWX loses communication with the touchpanel, the signal LED may remain

lit for 10 seconds before extinguishing. If the TPS-RFGWX loses operating power,

15 to 20 seconds are required to re-establish the communications with the touchpanel

after power is restored. The amount of time depends upon the environment and radio

traffic in the 2.4 GHz Spectrum.

Wi-Fi Technology

Wi-Fi (wireless fidelity) is the common term for high-frequency wireless local area

network (WLAN) technology that is gaining acceptance as an alternative to a wired

LAN in commercial as well as home network configurations. Wi-Fi is detailed in the

802.11b specification from the Institute of Electrical and Electronics Engineers

(IEEE) and is part of a series of wireless specifications together with 802.11,

802.11a, and 802.11g.

The TPS-RFGWX gateway is not “Wi-Fi compatible.” It does not comply with the

802.11 specifications, nor can it communicate with 802.11 devices. It is, however,

considered “Wi-Fi friendly,” since you can select a communication band (frequency

range) that will avoid interference with 802.11 devices. The gateway’s transceiver

(as well as the touchpanel’s) allows you to select one of ten possible bands (0

through 9) for communication. The bands define specific frequency ranges within

the 2.4 GHz Spectrum. The default band (Band 0) covers almost the entire spectrum

and is, therefore, not Wi-Fi friendly. The nine additional bands define narrower

ranges, leaving the rest of the frequency spectrum available for other RF devices,

thus making it possible to avoid interference. Refer to “Channel ID, Band, and

Power Setting” on page 9 for details.

As you configure the gateway for operation, you select a Channel ID to identify the

gateway for the touchpanel(s) communicating with it. Up to 15 touchpanels can

communicate with each gateway; up to 16 gateways can be included in one SIMPL

program.

You then select one of the ten frequency bands. Selection of a band is based on a

number of factors, most importantly the need to avoid interference with nearby RF

devices, and compliance with local communication laws. Crestron recommends

using Bands 5 (USA comp 1) through 9 (USA comp 5) within the US. Bands 1

through 4 (France, Spain, Japan, and Canada) are intended for use in Cresnet systems

outside the US.

2 • Two-Way RF Transceiver: TPS-RFGWX Operations Guide - DOC. 5847A

Crestron TPS-RFGWX Two-Way RF Transceiver

If you have two or more Crestron wireless RF devices in the Cresnet system, they

should all be set to the same band. If your system includes non-Crestron RF devices,

set the Crestron RF devices to a different band than the non-Crestron devices to

minimize the possibility of interference between them.

Touchpanel Compatibility

The ability to select frequency bands makes it possible for the TPS-RFGWX

gateway to communicate with touchpanels that are Wi-Fi friendly, such as the STX-

1700CXP, as well as those that are not. Gateways that are Wi-Fi-friendly (include

band selection) have product labels that include a seven-digit number beginning with

600 (e.g., 6002104). Product labels on earlier models of the gateway (fixed band; not

Wi-Fi friendly) included seven-digit alphanumeric codes beginning with ZA (e.g.,

ZA11308). Similarly, Wi-Fi friendly gateways can communicate with touchpanels

that are not so enabled as well as those that are. In either case, in order to

communicate, the gateway and touchpanel must be set to the same band and have

identical identity code settings (refer to “Identity Codes” on page 8 for details).

These three LEDs monitor the RF communications of the TPS-RFGWX. The SIG

LED illuminates when the TPS-RFGWX is in RF communication with a touchpanel.

This LED also flashes 20 times to indicate that the TPS-RFGWX has rebooted. The

Rx LED illuminates when a command is received from a touchpanel and Tx

illuminates when feedback is transmitted to a touchpanel. If the touchpanel goes out

of range, the Tx LED will flash every four to five seconds for approximately 30

seconds and then stops flashing (the unit stops transmitting if the touchpanel does not

come into range in the allotted time). If the touchpanel comes into range before the

TPS-RFGWX stops transmitting, the touchpanel display reverts to whatever screen

the control system has active. If the touchpanel comes into range after the TPS-

RFGWX stops transmitting, the user must touch the touchpanel screen to activate the

gateway and leave the out of range screen. Any messages sent to the touchpanel

while it was out of range will be sent after normal communication resumes.

Network Wiring

CAUTION: Use only Crestron power supplies for Crestron equipment. Failure to do

so could cause equipment damage or void the Crestron warranty.

NOTE: When installing network wiring, refer to the latest revision of the wiring

diagram(s) appropriate for your specific system configuration, available from the

Downloads | Product Manuals | Wiring Diagrams section of the Crestron website

(www.crestron.com)

When calculating the wire gauge for a network run, the length of the run and the

power factor (power usage in watts) of each network unit must be taken into

consideration. If multiple network units are to be daisy-chained, the power factors of

each unit must be added to determine the power factor of the entire chain. The length

of the run in feet and the power factor of the run (in watts) should then be used in the

following resistance equation.

NOTE: All network wiring must consist of two twisted-pairs. One twisted pair is the

+24V conductor and the GND conductor; the other twisted pair is the Y conductor

and the Z conductor.

NOTE: When daisy-chaining Cresnet units, strip the ends of the wires carefully to

avoid nicking the conductors. Twist together the ends of the wires that share a pin on

the network connector, and tin the twisted connection. Apply solder only to the ends

of the twisted wires. Avoid tinning too far up the wires or the end becomes brittle.

Insert the tinned connection into the Cresnet connector and tighten the retaining

screw. Repeat the procedure for the other three network conductors.

Identity Codes

The TPS-RFGWX gateway/transceiver uses three forms of identification for

recognition within a Cresnet system and to communicate with a TPS-XTXRF or

STX-1700CXP touchpanel: Cresnet identity (NET ID), channel ID, and band. The

8 • Two-Way RF Transceiver: TPS-RFGWX Operations Guide - DOC. 5847A

Crestron TPS-RFGWX Two-Way RF Transceiver

NET ID assignment must match the assignment made in the SIMPL Windows

project. In addition, a Low Power Mode setting lets you reduce the transmission

power to reduce or eliminate interference with other RF devices communicating with

or near the Cresnet system.

NET ID

For a definition of Viewport,
refer to the Note on page 12

Every piece of equipment and user interface within the Cresnet system requires a

unique NET ID. These codes are two-digit hexadecimal numbers from 03 to FE. The

NET ID of the unit must match the NET ID specified in the SIMPL Windows

program. The NET ID of the TPS-RFGWX is factory set to 52. The NET IDs of

multiple TPS-RFGWXs must all be unique and changed from a PC via the Crestron

Viewport. To set or change the NET ID of the TPS-RFGWX, complete the

following steps.

1. Attach only one TPS-RFGWX to the control system (verify that the
software is running).

2. Open the Crestron Viewport (Version 3.53).

Either launch the stand-alone version of Viewport, or start SIMPL
Windows or VT Pro-e, and from the menu bar, select Tools |
Viewport.

3. From the Viewport menu, select Functions | Set Network ID. The

software checks the baud rate and then opens the “Set Network ID”
window.

4. In the “Set Network ID” window, select the TPS-RFGWX from the

Current Network Devices text window.

5. From the Choose the new network ID for the selected device (Hex):

text box, select the new Net ID for the TPS-RFGWX.

6. Click Set ID to initiate the change. This will display the “ID

command has been sent” window.

7. In the “Command Complete” window, click OK.

8. In the Current Network Devices text window, verify the new NET ID

code.

9. In the “Set Network ID” window, click Close.

NOTE: The new NET ID code may also be verified by selecting Diagnostic |
Report Network Devices in the Viewport.

10. Attach each TPS-RFGWX to be added to the Cresnet system

individually and repeat this procedure as needed.

Channel ID, Band, and Power Setting

Each gateway communicating with a touchpanel must have a channel ID and band
assignment that matches the RF channel and band assignment of the touchpanel.

There are 16 possible channels ranging from 0 to F (hexadecimal number) and the
channel assigned to each touchpanel must be unique. Similarly, there are 10 possible
bands that can be selected, and the selection made for the touchpanel and the
gateway must match. Also, if two or more gateways are operating in close proximity
and experiencing interference problems, you can select the Low Power Mode to
reduce signal strength, which may eliminate the interference.

3. In the top portion of the “RFGWX Channel ID” window, select the

network ID of the gateway that requires the RF channel to be set.

4. In the middle portion of the window, select the desired channel ID

for each gateway (up to 16) and all touchpanels (up to 15) associated
with that gateway.
In the bottom portion of the window, select the desired band for the
gateway. The choices correspond with the band names shown in the
table on the next page. The table shows the 802.11b channels within
each band that are occupied by the STX-1700CXP. Selection of a
band is based on a number of factors, including the need to avoid
interference with nearby RF devices, and compliance with local
communication laws. In the US, Crestron recommends using Bands 5
(USA comp 1) through 9 (USA comp 5). Bands 1 through 4 (France,
Spain, Japan, and Canada) are intended for use in Cresnet systems
outside the US. The default setting is Band 0, USA (original), which
is not Wi-Fi friendly. Note that at this setting, the gateway can
communicate with the touchpanels whether they are Wi-Fi friendly
or not, since Band 0 is the default setting for both versions.

The TPS-RFGWX provides two-way wireless RF communication between a
Crestron control system and a Crestron Isys

TM

tilt touchpanel equipped with the
optional TPS-XTXRF Two-Way RF Transceiver Module or other similarly-equipped
Crestron touchpanels, such as the STX-1700CXP.

Although the device itself is not programmable, you can create a program that
includes a TPS-RFGWX using the Crestron programming tool SIMPL Windows.

SIMPL (Symbol Intensive Master Programming Language) is an easy-to-use
programming language that is completely integrated and compatible with all
Crestron system hardware. The objects that are used in SIMPL are called symbols.
SIMPL Windows offers drag and drop functionality in a familiar Windows

®

environment.

SIMPL Windows is Crestron's software for programming Crestron control systems.
It provides a well-designed graphical environment with a number of workspaces
(i.e., windows) in which a programmer can select, configure, program, test, and
monitor a Crestron control system.

To create a program with a TPS-RFGWX, consult the TPS-XTXRF Operations &
Installation Guide (Doc. 5844) or the STX-1700CXP 2-Way RF Wireless
Touchpanel Operations Guide (Doc. 6144). The latest versions of these guides can
be obtained from the Downloads | Product Manuals section of the Crestron website
(www.crestron.com)

.

For an example program including the TPS-RFGWX, refer to the program for the
STX-1700CXP which is available from the Downloads page (EXAMPLES Library)
of Crestron’s website (ftp://ftp.crestron.com

). Search for STX1700CXP.SMW.

Uploading and Upgrading

Assuming a PC is properly connected to the entire system, Crestron programming
software allows the programmer to upload programs and projects after their
development to the system and network devices. However, there are times when the
files for the program and projects are compiled and not uploaded. Instead, compiled
files may be distributed from programmers to installers, from Crestron to dealers,
etc. Even firmware upgrades are available from the Crestron website as new features
are developed after product releases. In those instances, one has the option to upload
via the programming software or to upload and upgrade via the Crestron Viewport.

NOTE: The Crestron Viewport utility accomplishes multiple system tasks, primarily
via an RS-232 or TCP/IP connection between the control system and a PC. It is used
to observe system processes, upload new operating systems and firmware, change
system and network parameters, and communicate with network device consoles and
touchpanels, among many other tasks. Viewport can also function as a terminal
emulator for generic file transfer. All of these functions are accessed through the
commands and options in the Viewport menus. Therefore, for its effectiveness as a
support and diagnostic tool, the Crestron Viewport may be preferred over
development tools when uploading programs and projects.

The following sections define how one would upgrade the firmware of the TPS­RFGWX. However, before attempting to upgrade, it is necessary to establish
communications.

recommends the use of PCMCIA cards, rather than USB-to-serial adapters. If a
USB-to-serial adapter must be used, Crestron has tested the following devices with
good results:

Belkin (large model) F5U103
I/O Gear GUC232A
Keyspan USA-19QW

Other models, even from the same manufacturer, may not yield the same results.

The procedure in this section provides details for RS-232 communication between
the PC and the control system. If TCP/IP communication is preferred, consult the
latest version of the Crestron e-Control Reference Guide (Doc. 6052) or the
respective Operations Guide for the control system. These documents are available
from the Downloads | Product Manuals section of the Crestron website
(www.crestron.com). Refer to the figure below for a typical connection diagram
when uploading files.

Note: Use a standard DB9 male to female “straight-through” cable.

Two-Way RF Transceiver Crestron TPS-RFGWX

Appendix A: Optimum RF Reception Guidelines

Many factors can affect the reliability of RF communication between an RF gateway
and an RF touchpanel. While an effort has been made to determine operating
specifications, some specifications are not constant. RF Communication can be
limited by several factors including but not limited to EMI (electromagnetic
interference), intervening objects, antenna orientation, and receiver placement. To
obtain maximum reliability and performance, some basic rules for installing RF
transceivers are listed below.

Minimize Interference

RF reception range can be hindered by spurious EMI noise that may interfere with or
mask the desired frequency thereby reducing useable range. EMI is generated by any
electrical device at various RF noise levels depending on the device. Sources of EMI
include computers, video equipment, digital processors, lighting dimmers, lighting
ballasts, motors or any large AC source. Every effort should be made to separate any
RF transceiver from these sources of RF noise including Audio Visual equipment in
racks. If a gateway must be installed in an equipment rack, make sure you have
ample separation between the equipment and the gateway.

NOTE: Check any 802.11b equipment operating near the Cresnet system to see that
it is using only channels that are not being used by the TPS-RFGWX gateway. If
necessary, change the gateway’s Band setting to avoid interference. Refer to
“Channel ID, Band, and Power Setting” on page 9 for details.

Gateway Placement

Optimum reception for any RF transceiver is obtained by installing the gateway
transceiver in an open area or shelf with a clear line of sight (no obstructions
between gateway and receiver). Crestron recommends that the gateway is at least
five to six feet high for best results. Avoid placing transceivers or transmitters at a
low height or on the ground. Placing RF equipment near metal objects, walls, corners
or metal enclosures will compromise RF propagation and reception. Try to avoid
installing gateways in equipment racks, service rooms, electrical closets or in rooms
other than that which the panel or transmitter is located.

Antenna Orientation

The antenna orientation on Crestron gateways has considerable effect on range and
reliability. Optimum performance is obtained by setting the antenna horizontally
(parallel to the ground). When absolutely necessary, two alternate orientations are
possible – each will be less effective than the horizontal orientation:

 Point the antenna vertically

 Point the antenna at a right angle to the gateway.

These may allow for rack or equipment closet doors to be shut but these orientations
may also compromise reception. Never point the antenna downward or directly
parallel to the front panel, this will decrease range and reliability. Refer to
illustrations on the next page for examples of the different antenna orientations.

NOTE: RF propagation is best from the sides of the antenna.
