infiNET™ Gateway/Transceiver:
C2N-MNETGW
Introduction
Features and Functions
• Two-way radio frequency (RF) wireless transceiver/gateway
• infiNET™ mesh network technology
• Dynamic discovery for fast, easy setup
• "Wi-Fi friendly" channel selection for trouble-free operation
• Up to 150 foot range indoors, 250 feet outdoors
• Supports up to 30 infiNET devices
infiNET™
Crestron's groundbreaking infiNET wireless technology provides reliable
2-way communications throughout a home or office structure without the
need for physical control wiring. Employing a 2.4 GHz mesh network
topology, every infiNET device functions as an RF repeater, increasing
effective range and reinforcing the complete network by providing
multiple redundant signal paths within the mesh network. Adding more
infiNET devices or repeaters to the network effectively increases the
range, strength, and reliability of the network.
Up to 30 infiNET dimmers, switches, and other devices can be linked to
a control system via a single C2N-MNETGW gateway. Additional
Operations Guide – DOC. 6317A infiNET™ Gateway/Transceiver: C2N-MNETGW • 1
infiNET™ Gateway/Transceiver Crestron C2N-MNETGW
gateways may be installed to support additional devices, with up to 16
gateways possible in a complete system (RF conditions allowing).
Easy Setup
Setting up a complete infiNET network is simple, utilizing dynamic
discovery to locate and acquire each RF device automatically. Every
device assigned to a common gateway automatically behaves as a
repeater for any other devices within range (approximately 150 feet
indoors), and additional repeaters may be added if necessary. At all
times, the C2N-MNETGW monitors each device on the network,
ignoring any other 2.4 GHz signals, and reconfiguring the entire network
automatically in response to new sources of interference and other
changes in RF conditions.
Applications
The following diagram shows a C2N-MNETGW in an infiNET
application with infiNET dimmers and a C2N-MNETRPT infiNET
repeater.

Uploading and Upgrading
Crestron recommends using the latest programming software and that
each device contains the latest firmware to take advantage of the most
recently released features. However, before attempting to upload or
upgrade it is necessary to establish communication. Once communication
has been established, files (for example, programs, projects or firmware)
can be transferred to the control system (and/or device). Finally, program
checks can be performed (such as changing the device ID) to ensure
proper functioning.
Establishing Communication
Use Crestron Toolbox for communicating with the C2N-MNETGW;
refer to the Crestron Toolbox help file for details. Indirect
communication via a control system is the sole method of communicating
with the C2N-MNETGW.

If a SIMPL Windows program is provided, it can be uploaded to the
control system using SIMPL Windows or Crestron Toolbox.
Check the Crestron website to find the latest firmware. (New users may
be required to register to obtain access to certain areas of the site,
including the FTP site.)
• Upgrade C2N-MNETGW firmware via Crestron Toolbox.
• Establish indirect communications with the C2N-MNETGW and
display the “System Info” window.
• Select Functions | Firmware… to upgrade the C2N-MNETGW
firmware.
Program Checks
Display the network device tree (Tools | Network Device Tree) to show
all network devices connected to the control system and all infiNET
devices that have been acquired by the C2N-MNETGW. Right-click on
the C2N-MNETGW to display actions that can be performed on the
C2N-MNETGW.
The function MNET Gateway… is used to set the operating channel
mode of the C2N-MNETGW and can also be used to acquire infiNET
devices to the C2N-MNETGW.
For information on setting the operating channel and acquiring devices,
refer to “Operation” on page 18.
Operations Guide – DOC. 6317A infiNET™ Gateway/Transceiver: C2N-MNETGW • 17
infiNET™ Gateway/Transceiver Crestron C2N-MNETGW
Operation
Operating
Channel
The operating channel mode of the C2N-MNETGW must be set prior to
operation using Crestron Toolbox. The C2N-MNETGW can operate on
one of 16 channels. The C2N-MNETGW can operate on a fixed channel
that is set by the installer or it can automatically set itself to the clearest
channel.
For systems using multiple gateways or systems operating in
environments containing other devices that use similar frequencies,
Crestron recommends setting the C2N-MNETGW to operate on a fixed
channel to avoid RF interference with other devices in the vicinity.
Ideally, each gateway should operate on its own channel to avoid
interfering with other gateways operating in the vicinity. The infiNET
signal protocol prevents data intended for one gateway and its devices
from being received by another gateway and its devices.
For optimum performance when installing a C2N-MNETGW in a Wi-Fi
environment, do not set the C2N-MNETGW to a channel within a Wi-Fi
channel band.
• Gateway channels 11- 14 are within Wi-Fi channel 1 band.
• Gateway channel 15 is adjacent to Wi-Fi channels 1 and 6.
• Gateway channels 16-19 are within Wi-Fi channel 6 band.
• Gateway channel 20 is adjacent to Wi-Fi channels 6 and 11.
• Gateway channels 21- 24 are within Wi-Fi channel 11 band.
• Gateway channel 25 is adjacent to Wi-Fi channel 11.
• Gateway channel 26 is neither within nor adjacent to any Wi-Fi
band.
For detailed information on infiNET channels, refer to “Appendix A:
The infiNET Spectrum” on page 27.
For systems with one gateway and minimal interference from other
devices that use similar frequencies, Crestron recommends setting the
C2N-MNETGW to automatically select the operating channel.
18 • infiNET™ Gateway/Transceiver: C2N-MNETGW Operations Guide – DOC. 6317A
Crestron C2N-MNETGW infiNET™ Gateway/Transceiver
After establishing communications with the C2N-MNETGW (refer
“Establishing Communication” on page 16), use the MNET Gateway…
function to set the operating channel mode and the operating channel. For
more information, refer to the Crestron Toolbox help file.
Acquire
Devices
Crestron’s infiNET devices can communicate with a C2N-MNETGW
only if they have been acquired by that C2N-MNETGW (even if the
C2N-MNETGW and the device are operating on the same channel). To
add infiNET devices to the infiNET network, the C2N-MNETGW must
be in the Acquire mode. The Acquire mode can be activated from
Crestron Toolbox (recommended) or with the ACQUIRE button on the
C2N-MNETGW.
NOTE: The Acquire mode can be activated approximately 15 seconds
after applying power to the C2N-MNETGW.
NOTE: In an environment with multiple gateways, only one gateway
should be in the Acquire mode at a time.
NOTE: The C2N-MNETGW must be placed in the Acquire mode
before an infiNET device is placed in the Acquire mode.
Via Crestron Toolbox:
Entering the Acquire mode from Crestron Toolbox provides the
installer with a visual account of devices as they are acquired.
After establishing communications with the C2N-MNETGW
(refer “Establishing Communication” on page 16), use the MNET
Gateway… function to acquire devices. For more information,
refer to the Crestron Toolbox help file.
NOTE: When acquiring devices using Crestron Toolbox, the
control system is in passto mode. The program in the control
system is paused and will resume after the C2N-MNETGW leaves
the Acquire mode.
NOTE: If the acquired devices have never had an MNET ID
assigned, they will be acquired with the default MNET ID 01.
Operations Guide – DOC. 6317A infiNET™ Gateway/Transceiver: C2N-MNETGW • 19
infiNET™ Gateway/Transceiver Crestron C2N-MNETGW
Via the ACQUIRE Button:
1. Press ACQUIRE on the C2N-MNETGW to enter the
Acquire mode. The accompanying LED will illuminate
indicating that it is ready to link to infiNET devices.
NOTE: The Acquire mode will automatically deactivate
after 30 minutes.

described in its respective manual. (Once each device
acquires the gateway, it will function as a repeater to
reinforce the infiNET network.) The device will be
automatically acquired by the gateway within five minutes
after it enters the Acquire mode.
3. Repeat step 2 for each device to be acquired.
4. Press ACQUIRE on the C2N-MNETGW to exit the
Acquire mode. The LED will turn off.

In order to ensure optimum performance over the full range of your
installation topology, Crestron Certified Wire and only Crestron Certified
Wire may be used. Failure to do so may incur additional charges if

Calculate
Power
CAUTION: Use only Crestron power supplies for Crestron equipment.
Failure to do so could cause equipment damage or void the Crestron
warranty.
CAUTION: Provide sufficient power to the system. Insufficient power
can lead to unpredictable results or damage to the equipment. Please use
the Crestron Power Calculator to help calculate how much power is
needed for the system (http://www.crestron.com/calculators).
When calculating the length of wire for a particular Cresnet run, the wire
gauge and the Cresnet power usage of each network unit to be connected
must be taken into consideration. Use Crestron Certified Wire only. If
Cresnet units are to be daisy-chained on the run, the Cresnet power usage
of each network unit to be daisy-chained must be added together to
determine the Cresnet power usage of the entire chain. If the unit is
home-run from a Crestron system power supply network port, the
Cresnet power usage of that unit is the Cresnet power usage of the entire
run. The wire gauge and the Cresnet power usage of the run should be
used in the following equation to calculate the cable length value on the
equation’s left side.
Cable Length Equation
L = Length of run (or chain) in feet
R = 6 Ohms (Crestron Certified Wire: 18 AWG (0.75 MM ))
or 1.6 Ohms (Cresnet HP: 12 AWG (4 MM ))
P = Cresnet power usage of entire run (or chain)

L <
Where:

R x P
Make sure the cable length value is less than the value calculated on the
right side of the equation. For example, a Cresnet run using 18 AWG
Crestron Certified Wire and drawing 20 watts should not have a length of
run more than 333 feet. If Cresnet HP is used for the same run, its length
could extend to 1250 feet.
NOTE: All Crestron certified Cresnet wiring must consist of two
twisted pairs. One twisted pair is the +24V conductor and the GND
conductor and the other twisted pair is the Y conductor and the Z
conductor.

Strip and Tin
Wire
Add Hubs
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 conductors.
For larger networks (i.e., greater than 28 network devices), it may
become necessary to add a Cresnet Hub/Repeater (CNXHUB) to
maintain signal quality throughout the network. Also, for networks with
lengthy cable runs it may be necessary to add a Hub/Repeater after only
20 devices.

Appendix A: The infiNET Spectrum
Crestron’s infiNET network provides 16 RF channels in the 2.4GHz ISM
band, specifically IEEE 802.15.4 channels 11 through 26. The 16
channels define the frequencies at which the infiNET device will
communicate.
Crestron’s infiNET devices on different channels will not communicate
nor interfere with each other. However, since some of the channels are in
the 2.4GHz ISM band (as shown in the following diagram), interference
can occur with other devices using this band, such as 802.11b Wi-Fi
devices, Crestron TPS-XTXRF devices, or Zigbee devices. However, the
differing protocols will not allow a link to be established or data to be
transferred. Wireless 2.4GHz telephones and microwave ovens may also
cause interference with the network.

To manage interference that may be present at installation time or may be
introduced later, the C2N-MNETGW has the ability to automatically
select a channel to operate on based on an evaluation of RF signal levels
on each channel. The gateway and devices are therefore designed to be
able to track and, if necessary, re-locate to channels with less
interference.

Appendix B: Optimum RF Reception Guidelines
Many factors can affect the reliability of RF communication between
infiNET gateways, repeaters, and devices. 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 electromagnetic interference (EMI), intervening
objects, antenna orientation, and device placement. To obtain maximum
reliability and performance, some basic rules for installing infiNET
gateways 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 802.11 equipment operating near the Cresnet system
to ensure that it is only using channels that are not being used by the
C2N-MNETGW. If necessary, change the gateway’s channel setting to
avoid interference. Refer to “Operating Channel” on page 18 for details.
For a description of the infiNET spectrum, refer to “Appendix A: The
infiNET Spectrum” on page 27.
Gateway Placement
Optimum reception for any infiNET gateway is obtained by installing the
gateway in an open area or shelf with a clear line of sight (no
obstructions between gateway, repeaters, and other infiNET devices).
Crestron recommends that the gateway be placed at least five to six feet
high for best results. Avoid placing gateways 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
28 • infiNET™ Gateway/Transceiver: C2N-MNETGW Operations Guide – DOC. 6317A
Crestron C2N-MNETGW infiNET™ Gateway/Transceiver
installing gateways in equipment racks, service rooms, or electrical
closets.
Antenna Orientation
The antenna orientation on the C2N-MNETGW can have considerable
effect on the signal range and reliability. In most applications, the
antenna should be set vertically as shown in the following diagrams.
Vertical Orientation
Operations Guide – DOC. 6317A infiNET™ Gateway/Transceiver: C2N-MNETGW • 29
infiNET™ Gateway/Transceiver Crestron C2N-MNETGW
If placing the antenna vertically causes it to lay parallel to a metal surface
(i.e. a metal wall), the antenna should be oriented horizontally
(perpendicular to the metal surface) as shown in the following diagram.
Horizontal Orientation
NOTE: RF propagation is best from the sides of the antenna.
For specific information on where to place the C2N-MNETGW, refer to
“Gateway Placement” on page 28.
