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.

Evaluation Results: Complies Details: The maximum permissible exposure (MPE) is predicted by using Equation (3) of Section 2 of FCC OET Bulletin 65, Edition 97-01: S = PG/4πR 2 where: S = power density (in appropriate units, e.g. mW/cm 2 ) P = power input to the antenna (in appropriate units, e.g., mW) G = power gain of the antenna in the direction of interest relative to an isotropic radiator R = distance to the center of radiation of the antenna (appropriate units, e.g., cm) P = 86.7 mW, G = 1.7783 (2.5 dBi), R = 20 cm S = 0.0307 mW/cm 2 = 0.307 W/m 2 MPE limit for uncontrolled exposure at prediction frequency: 1 mW/cm 2 Maximum allowable antenna gain: 17.63 dBi Margin of Compliance at 20 cm = 15.13 dB FCC ID: EROCWDHR IC: 5683C-CWDHR RF Exposure Page 2 of 2 RF Exposure Analysis 2. SAR Test Exclusion analysis SAR Test Exclusion: [(max. power of channel, mW) / (min. test separation distance, mm)] x [√f (GHz) ] ≤ 7.5 Evaluation Results: Complies Details: The modules are designed for use on extremities only exposure conditions. Duty cycle measurement and calculation are included in Theory of Operation, so does the minimum test separation distance. Max. power of channel: 86.7 mW Duty cycle: 0.052564 Source-based time-averaged max. power: 4.6 mW Min. test separation distance: 6 mm f (GHz) : 2.44 GHz [(4.6 mW) / (6 mm)] x [√2.44 GHz] = 1.2 ≤ 7.5 The EUT satisfy the SAR Test Exclusion Threshold condition.
