2-Way RF Wireless Touchpanel Crestron STX-1700CXP
2 • 2-Way RF Wireless Touchpanel: STX-1700CXP Operations Guide - DOC. 6227A
Included with the STX-1700CXP are a Crestron High Performance Rechargeable
Battery Pack (ST-BTPN) and a Docking Station (ST-DSN) that docks the touchpanel
and/or recharges the ST-BTPN. An external power pack (PW-1215 for domestic use
or PWI-1215 for international use) is also provided to power the touchpanel. Refer to
the latest revisions of the documentation supplied with these items for details.
NOTE: The ST-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.
The touchpanel is also available in an international version, the STXI-1700CXP.
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-1700CXP 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 the “ADDITIONAL RF
SETUP” illustration and supporting text on page 10 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
through 4 (France, Spain, Japan, and Canada) are intended for use in Cresnet systems
outside the US.
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.
When configuring a Cresnet system that includes Crestron RF wireless devices that
broadcast in the 2.4 GHz spectrum, in a facility that also contains one or more
