User Manual
2 2.4GHz Radio Module User Guide
SPI Interface/Connection to Motherboard:
The Radio Module employs an eight-pin socket to connect to a motherboard 8-pin header. This interface
is for the 3.0 VDC power source and all necessary data lines to communicate with the radio module.
Mounting:
The Radio Module has four mounting holes. The module is intended to be pushed down and snapped
onto a motherboard containing four snap lock nylon standoffs. At the same time, the 8-pin connector will
be engaged.
Antenna:
The 2.4G Radio Module employs a Reverse SMA connector to the antenna to prevent use of antennas
other than the type specified. Typically an omni-directional ½- wave dipole antenna is supplied for most
applications, with alternative antennas only approved for special, specifically tested applications.
FCC and Industry Canada Compliance:
The Johnson Controls 2.4G RF Module was tested standalone with a one meter cable interfacing the
module with its host Receiver/Translator motherboard and found to be compliant with part 15 regulations.
An FCC/IC ID label is to be affixed to each unit at the time of manufacture. Since this printed circuit board
is mounted inside various enclosures, a product label on that enclosure indicates the FCC ID and IC
identification. The Johnson Controls 2.4G RF Module is compliant with Part 15.247. It complies with the
RF exposure requirements of Parts 15.247, 2.1091, and 2.1093
Compliance Statement (Part 15.19)
This device complies with Part 15 of the FCC Rules.
Operation is subject to the following two conditions: This device may not cause harmful interference,
and this device must accept any interference received, including interference that may cause
undesired operation.
Warning (Part 15.21)
Changes or modifications not expressly approved by the party responsible for compliance could void
the user’s authority to operate the equipment.
20 cm Separation Distance
To comply with FCC’s RF exposure limits for general population / uncontrolled exposure, the
antenna(s) used for this transmitter must be installed to provide a separation distance of at least 20
cm from all persons and must not be co-located or operating in conjunction with any other antenna or
transmitter.
Installers Responsibility to the FCC Rules and Regulations
The Johnson Controls 2.4G RF Module has been certified per FCC Part 15 rules for integration into
products without further testing or certification. To fulfill the FCC certification requirements the Installer
of the Johnson Controls 2.4G RF Module must ensure that the information provided on the Johnson
Controls 2.4G RF Module Label is placed on the outside of the final product.
The Johnson Controls 2.4G RF Module is labeled with its own FCC ID Number. If the FCC ID is not
visible when the module is 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: CB2-RFMOD2400A”
or
“Contains FCC ID: CB2-RFMOD2400A”
The Installer of the Johnson Controls 2.4G RF Module must only use the approved antenna,
that has been certified with this module.
The Installer of the Johnson Controls 2.4G RF Module must test their final product configuration to
comply with Unintentional Radiator Limits before declaring FCC compliance per Part 15 of the FCC
rules.
