InfiNET™ Gateway/Transceiver Crestron C2N-MNETGW
The gateway receives RF signals from one or more infiNET devices such
as the CLW-DIM1/4RF and CLW-DIMS1/4RF line of infiNET dimmers
and the CLW-SW1/4RF and CLW-SWS1/4RF line of infiNET switches,
and relays them to the Crestron control system. It also relays commands
from the control system to devices on the infiNET network. Up to 30
infiNET devices (including C2N-MNETRPT repeaters) can communicate
with one C2N-MNETGW and, if more devices are needed, more
C2N-MNETGW devices may be added to a Cresnet
®
network.
InfiNET Technology
The C2N-MNETGW is a part of Crestron’s line of network devices using
infiNET network technology. InfiNET technology is “Wi-Fi” friendly
and provides fault tolerance and increased reliability as network devices
are added.
Crestron infiNET devices are compliant with IEEE specification 802.15.4
and are not “Wi-Fi compatible”. infiNET devices do not comply with the
802.11 specifications, nor can they communicate with 802.11 devices
even though they may interact with other 802.11 devices. This interaction
may manifest itself as RF interference. However, the differing protocols
will not allow a link to be established or data to be transferred between
devices using different protocols. infiNET devices are considered “Wi-Fi
friendly” since Wi-Fi and infiNET are “collision based” and attempt to
avoid simultaneous transmission. A communication band (frequency
range) can be selected to avoid interference with 802.11 devices such as
wireless computer networks. The transceiver of every infiNET network
device uses one of sixteen possible bands (11 through 26) for
communication. The bands define specific frequency ranges within the
2.4 GHz spectrum. Each of the bands define narrower ranges, leaving the
rest of the frequency spectrum available for other RF devices, thus
making it possible to avoid interference. The operating band can be
manually selected by the installer or automatically selected by a gateway
device like the C2N-MNETGW. For a detailed description of the
infiNET spectrum, refer to “Appendix A: The infiNET Spectrum” on
page 38. For information on setting the operating band, refer to
“Configuring the infiNET Network” on page 12.
The C2N-MNETGW operates on the 2.4 GHz “ISM band” (2400 MHz to
2483.6 MHz) at 10 mW. The output power of this device allows RF
signals to travel approximately 150 feet indoors and 250 feet outdoors
