Wall Mount 2-Way RF Wireless Touchpanel
2 • Wall Mount 2-Way RF Wireless Touchpanel: STX-1700CXPW
NOTE: The STX-1700CXP is supplied with an optional bezel, two 5-button switch
actuators, and ten black pushbuttons (blank), five for each side of the LCD screen.
You can use these buttons to access any frequently used commands. Refer to
"Appendix B: Installation of Optional Pushbuttons" for instructions to install the
optional switches, buttons, and bezel.
NOTE: Two options, 1700C-BTNB (black buttons) or 1700C-BTNS (silver buttons)
can be purchased to provide custom engraved buttons for your touchpanel. Contact
Crestron customer support for more information.
When not docked in the DA-1700CW, the "Wi-Fi friendly" touchpanel is a
handheld, two-way wireless radio frequency (RF) transceiver that utilizes 2.4 GHz
spread spectrum technology to communicate through Crestron's gateway/transceiver,
the TPS-RFGWX (sold separately), to the Cresnet system. (Refer to "Wi-Fi
Technology" below and "Gateway Compatibility" on page 3 for more details.) The
two-way communications provide control of third party and Cresnet devices and
dynamic onscreen feedback for real-time confirmation of commands. Up to 15
touchpanels can communicate with one TPS-RFGWX. RF signals can travel from a
minimum of three feet up to a maximum between 100 - 200 feet; the range is
dependent on location of the touchpanel, the construction of the building, and
obstructions and RF interference from other devices. Location and antenna
orientation of the TPS-RFGWX also are important factors in RF
reception/transmission.
The touchpanel is also available in an international version, the STXI-1700CXPW.
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 specified 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 STX-1700CXPW touchpanel 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 touchpanel's
transceiver (as well as the gateway'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 "ADDITIONAL RF SETUP"
illustration on page 15 for details.
As you configure the touchpanel for operation, you select an RF channel to identify
the gateway that will communicate with the touchpanel. Up to 16 gateways can be
included in one SIMPL program, and up to 15 touchpanels can communicate with
each gateway.
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
