Two-Way RF Transceiver Module:
MNET-CWD1012
Introduction
Functions and Features
The MNET-CWD1012 (hereafter referred to as “module”) is a two-way radio
frequency (RF) module that utilizes the 2.4 GHz frequency band to communicate
with other devices.
The module operates according to the IEEE 802.15.4 specification and can be
configured to minimize the possibility of interference with other devices.
The module receives RF signals from one or more Crestron MNET devices and can
transmit these signals over the air or over a cable run for further processing
(depending on the application).
Functional Summary
•
Two-way RF transceiver
− 2.4 GHz frequency band, IEEE 802.15.4 specification
− Range from 3 feet to 100 ft.
− Range is effectively increased with the use of additional MNET
devices or repeaters
− Operates on one of sixteen available channels to establish optimal
signal quality
The transceiver uses a 10 milliwatt signal that can travel up to approximately 100
feet indoors. The range is dependent on the construction of the building,
obstructions, and RF interference from other devices. Adding more modules will
increase the range of transmission. The location of the module and the orientation of
its antenna are also important factors in determining RF performance.

1.
The location of the module and the orientation of the antenna are important factors in the RF
performance. With the unit located outside of any metal enclosures, the antenna is adjusted to
achieve the best range. The range is dependent on its placement and the building in which it is used.
The construction of the building, obstructions, and RF interference from other devices are factors
determining the effective range of the unit. To prevent unit-to-unit RF interference, multiple
modules operating at the same frequencies should not be installed within 3-5 feet of each other.
Physical Description
The module, shown below, consists of various components attached to a printed
circuit board. A SMA non-standard female antenna port is located at edge of the
circuit board for attaching the included dipole antenna while a 31-pin interface
connector is located on the underside of the circuit board.

Antenna
This SMA non-standard male antenna port is located at edge of the circuit board for
attaching the included dipole antenna.
APPROVED ANTENNAS:
The MNET-CWD1012 antenna interface has a unique coupling designed to ensure
that no antenna other than the one supplied shall be used with the device.
Replacement antennas may be purchased from Crestron according to the following

Industry Compliance
Labeling Requirements
If the FCC ID on the MNET-CWD1012 is not visible when the module is installed
inside another device, then the outside of the device into which the module is
installed must also display a label referring to the enclosed module. This exterior
label can use wording such as the following: “Contains Transmitter Module FCC ID:
EROCWD1012” or “Contains FCC ID: EROCWD1012.” Any similar wording that
expresses the same meaning may be used.
Compliance Statement (Part 15.19 )
This device complies with Part 15 of the FCC Rules. Operation is subject to the
following two conditions:
1.
This device may not cause harmful interference, and
2.
This device must accept any interference received, including interference
that may cause undesired operation.
Warning (Part 15.21 )
Changes or modifications not expressly approved by the party responsible for
compliance could void the user’s authority to operate the equipment.
RF Exposure (OET Bulletin 65 )
To comply with FCC RF exposure requirements for mobile transmitting devices, this
transmitter should only be used or installed at locations where there is at least 20cm
separation distance between the antenna and all persons.
Industry Canada Statement
The term "IC" before the certification/registration number only signifies that the
Industry Canada technical specifications were met.
IC: 5683A-CWD1012
Antenna Requirements:
The module must be installed such that the antenna connector is accessible for direct
antenna connection in the final configuration. If any cable or antenna other than that
provided with the MNET-CWD1012 is used, then the FCC authorization is no longer
considered valid and the FCC ID cannot be used on the final product. In these
circumstances, the OEM integrator will be responsible for reevaluating the end
product (including the transmitter) and obtaining a separate FCC authorization.
FCC Radiation Exposure Statement:
This equipment complies with FCC radiation exposure limits set forth for an
uncontrolled environment. This equipment should be installed and operated with

Two-Way RF Transceiver Module
minimum distance 20cm between the radiator & your body. This transmitter must
not be co-located or operating in conjunction with any other antenna or transmitter.
This device is intended only for OEM integrators under the following
conditions:
1.
The antenna must be installed such that 20 cm is maintained between the
antenna and users, and
2.
The transmitter module may not be co-located with any other transmitter or
antenna.
As long as the two conditions above are met, further transmitter test will not be
required. However, the OEM integrator is still responsible for testing their endproduct for any additional compliance requirements required with this module
installed (for example, digital device emissions, PC peripheral requirements, etc.).
IMPORTANT NOTE: In the event that these conditions cannot be met (for
example certain laptop configurations or co-location with another transmitter), then
the FCC authorization is no longer considered valid and the FCC ID cannot be used
on the final product. In these circumstances, the OEM integrator will be responsible
for reevaluating the end product (including the transmitter) and obtaining a separate
FCC authorization.
Setup
Hardware Hookup
Refer to the hookup diagram below, which shows the connections made to the
module. Complete the connections in any order.
NOTE: To prevent unit-to-unit RF interference, multiple modules operating at the
same frequencies should not be installed within three to five feet of each other.

regarding how to install or remove this RF module in the users manual of the end
product which integrate this module.
The users manual for OEM integrators must include the following information in a
prominent location
“IMPORTANT NOTE: To comply with FCC RF exposure
compliance requirements, the antenna used for this transmitter
must be installed to provide a separation distance of at least 20
cm from all persons and must not be co-located or operating in
conjunction with any other antenna or transmitter.”
The users manual for OEM integrators device must include the following
