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 CWD6781 2 • Two-Way RF Transceiver Module: CWD6781 Operations Guide - DOC. 7039A Specifications The table below is a summary of specifications for the CWD6790. Specifications of the CWD6781 SPECIFICATION DETAILS Power Requirements 0. 825 Watts (5VDC @ 0.165A) Operating Frequency 2400 MHz to 2483.5 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) Antenna Chip Dimensions Width: 1.88 in (0.477 cm) Height: 0.82 in (0.208 cm) Depth: 0.100 in (0.254 cm) 1. 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.
