This document was written by the Technical Publications department at Crestron. ©2013 Crestron Electronics, Inc. Regulatory Compliance Federal Communications Commission (FCC) Compliance Statement This device complies with part 15 of the FCC Rules. Operation is subject to the following conditions: (1) this device may not cause interference and (2) this device must accept any interference received, including interference that may cause undesired operation. CAUTION: Changes or modifications not expressly approved by the manufacturer responsible for compliance could void the user’s authority to operate the equipment. NOTE: This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures:  Reorient or relocate the receiving antenna  Increase the separation between the equipment and receiver  Connect the equipment into an outlet on a circuit different from that to which the receiver is connected  Consult the dealer or an experienced radio/TV technician for help Industry Canada (IC) Compliance Statement This device complies with Industry Canada license-exempt RSS standard(s). Operation is subject to the following two conditions: (1) this device may not cause interference and (2) this device must accept any interference, including interference that may cause undesired operation of the device. Under Industry Canada regulations, this radio transmitter may only operate using an antenna of a type and maximum (or lesser) gain approved for the transmitter by Industry Canada. To reduce potential radio interference to other users, the antenna type and its gain should be so chosen that the equivalent isotropically radiated power (e.i.r.p.) is not more than that necessary for successful communication. Industrie Canada (IC) Déclaration de conformité Le présent appareil est conforme aux CNR d'Industrie Canada applicables aux appareils radio exempts de licence. L'exploitation est autorisée aux deux conditions suivantes : (1) l'appareil ne doit pas produire de brouillage, et (2) l'utilisateur de l'appareil doit accepter tout brouillage radioélectrique subi, même si le brouillage est susceptible d'en compromettre le fonctionnement. Conformément à la réglementation d'Industrie Canada, le présent émetteur radio peut fonctionner avec une antenne d'un type et d'un gain maximal (ou inférieur) approuvé pour l'émetteur par Industrie Canada. Dans le but de réduire les risques de brouillage radioélectrique à l'intention des autres utilisateurs, il faut choisir le type d'antenne et son gain de sorte que la puissance isotrope rayonnée équivalente (p.i.r.e.) ne dépasse pas l'intensité nécessaire à l'établissement d'une communication satisfaisante. To satisfy RF exposure requirements, this device and its antenna must operate with a separation distance of at least 20 centimeters from all persons and must not be collocated or operating in conjunction with any other antenna or transmitter.

Crestron CWD6790R1 Two-Way RF Transceiver Module Operations Guide - DOC. 7559A Two-Way RF Transceiver Module: CWD6790R1  1  2.4 GHz frequency band, IEEE 802.15.4 specification  Range from 3 feet to 50 ft.  Operates on one of sixteen available channels to establish optimal signal quality Two-Way RF Transceiver Module: CWD6790R1 Functions and Features The CWD6790R1 (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 devices and can transmit these signals over the air for further processing (depending on the application). Functional Summary
Two-Way RF Transceiver Module Crestron CWD6790R1 2  Two-Way RF Transceiver Module: CWD6790R1 Operations Guide - DOC. 7559A Specifications The table below is a summary of specifications for the CWD6790R1. Specifications of the CWD06790R1 SPECIFICATION DETAILS Power Requirements 0.58 W (5.0 Vdc @ 0.115 A) Operating Frequency 2400 MHz to 2483.5 MHz (802.15.4 compliant) Operating Ranges* Minimum Distance Maximum Distance Indoors (without repeater device) 3 ft 50 ft Available Channels 16 (numbered 11 through 26 per 802.15.4) RF Output Power 1.7 mW Dimensions Width: 1.64 in (4.15 cm) Height: 2.35 in (5.98 cm) Depth: 0.66 in (1.68 cm) Antenna Gain: 3.98 dBi max. Type: 5/8-wavelength, Inverted-F, Center Frequency 2.45 GHz Construction: Post and strip * The location and orientation of the module 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 set of spring loaded pogo-pins connect to the antenna that is mounted in the plastic button frame. A 10-pin header is provided for the application-specific installation. There are six (6) different build options for this module. The options specify the number of installed push buttons/switches, the number and color of installed LEDs.
