Crestron CWDHR Two-Way RF Transceiver Module Operations Guide - DOC. 7657A Two-Way RF Transceiver Module: CWDHR  1  2.4 GHz frequency band, IEEE 802.15.4 specification  Range from 3 feet to 550 feet.  Operates on one of 16 available channels to establish optimal signal quality Two-Way RF Transceiver Module: CWDHR Introduction The CWDHR (hereafter referred to as “module”), with an SMD antenna, is a two-way radio frequency (RF) module that utilizes the 2.4 GHz frequency band to communicate with other devices. There are two versions: PA07414 and PA07424. The module operates according to the IEEE 802.15.4 specifications. 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). Features and Functions
Two-Way RF Transceiver Module Crestron CWDHR 2  Two-Way RF Transceiver Module: CWDHR Operations Guide - DOC. 7657A Specifications Specifications for the CWDHR are listed in the following table. CWDHR Specifications SPECIFICATIONS DETAILS Power Requirements Four (4) disposable 1.5 V “AAA” alkaline batteries Operating Frequency 2400 MHz to 2483.5 MHz (802.15.4 compliant) Operating Ranges* Minimum Distance 3 feet Maximum Distance Indoors (without repeater device) 550 feet Available Channels 16 (numbered 11 through 26 per 802.15.4) Serial Communications SPI, 3.0 Vdc Nominal Antenna Gain 2.5 dBi max. peak Type Ceramic chip antenna Frequency 2.4 GHz to 2.5 GHz Dimensions (PA07414) Height 1.850 in Width 0.303 in Depth 7.248 in Dimensions (PA07424) Height 1.850 in Width 0.303 in Depth 5.967 in * The location and orientation of the module are important factors in 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.
