Crestron CWDHR Two-Way RF Transceiver Module
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
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

* 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.

Labeling
The host device shall be properly labeled to identify the modules within the host
device.
The FCC and Industry Canada certification label of a module shall be clearly visible
at all times when installed in the host device. Otherwise the host device must be
labeled to display the FCC and Industry Canada certification numbers of the module,
preceded by the words “Contains Transmitter Module” or the word “Contains”, or
similar wording expressing the same meaning as follows:
Contains FCC ID: EROCWDHR
Contains IC: 5683C-CWDHR
Documentation
The OEM integrator must be aware not to provide information to the end user
regarding how to install or remove this RF module in the user manual of the end
product.
The user’s manual for OEM integrators must include the following information in a
prominent location:
IMPORTANT NOTE: To comply with FCC RF exposure compliance
requirements, the antenna used for this transmitter must be installed to provide a
separation distance of at least 20 cm from all persons.
