Crestron MNET-CWD1012 Two-Way RF Transceiver Module Hardware Guide - DOC. 6351 Two-Way RF Transceiver Module: MNET-CWD1012 • 1 • 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 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 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.

Specifications of the MNET-CWD1012 SPECIFICATION DETAILS Power Requirements 0.75 Watts (5VDC @ 0.150A) Operating Frequency 2400 MHz to 2483.6 MHz (802.15.4 compliant) Operating Ranges¹ Minimum Distance Maximum Distance Indoors (without repeater device) 3 ft 100 ft Available Channels 16 (numbered 11 through 26 per 802.15.4) RF Output Power 10 mW Serial Communications TTL Level, 38400 Baud, 8 data bits, 1 stop bit, no parity, software flow control Antenna (included) Type Antenna Connector V.S.W.R Gain Dipole Antenna SMA Non-Standard Female Connector with ¼-36 UNS2B Screw 1.9 : 1 2.0 dBi ±0.5 Dimensions Width: 1.50 in (3.81 cm) Height: 2.50 in (6.35 cm) Depth: 0.36 in (0.91 cm) 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.

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 description: Part Number: ANXX2400R00MHZ-2 Description: ANTENNA, 2400.00MHZ, DIPOLE, SMA, REVERSE POLARITY, FEMALE 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

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 end-product 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.
