Two-Way RF Transceiver Module: CWD7567

Functions and Features

The CWD7567 (hereafter referred to as “module”) is a two-way radio frequency (RF) module that
utilizes the 2.4 GHz fr eq u ency band t o communicat e wi th other devices.

The module oper at es a ccor din g t o the IE EE 8 02. 15. 4 speci ficat ion and can be config ured t o minimi ze
the possibility of interference with other devices.

The module receives RF signals from one or more Crestr on devi ces and can transmit these sign als over
the air for further processing (depending on the application).

Functional Summ ary

• Range fr om 3 fee t to 50 ft.

• Operates on one of sixteen available channels to establish optimal

signal q uality

1. The lo cation and orien tation of the module are impo r tant 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 i s used. The constru ction 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 sa m e fr e qu e ncies shou ld not be installe d w ithin 3-5 f eet of eac h o t her.

Physical Description

The module, shown belo w, consist s of various compone nts attached to a print e d circ uit boa rd.
There are three (3) different build options for this module. The options specify the number of installed

push buttons/switches, the number and color of installed LEDs.

Labeling

If the FCC identification numb er is not visibl e wh en the module i s installed inside another device, then
the outside of the device into which the module is installed must also display a label referring to the
enclosed module. This exterior label can use wording such as the following: “Contains Transmitter
Module FCC ID: EROCWD7567” or “Contains FCC ID: EROCWD7567.” Any similar wording that
expr ess es the same m ean ing may be used.
