1.0 Device Overview and Description
The B014 RF 2.4GHz module has been designed to extend wireless communication in IMET radio
control systems in the 2.4GHz to 2.4835GHz band, making 38 channels available in the assigned
band. The device is integrated into the logic units of the IMET industrial remote control systems, to
allow greater coverage and reliability in the communication between the remote unit (radio control
or transmitter unit M880 RAY) and other receiver unit of the M880 Series.
The B014 module mounts two antennas with two U.FL 50Ω connectors to ensure greater coverage
and stability in radio communication.
The B014 is assembled by screws and has its own internal switching power supply and voltage
regulators one for the RF part and one for the microcontroller logic part and its own oscillators.
The module can it be easily integrated (surface mount) with M880 systems, freeing up the design
dedicated to the RF communication part and from the compliance tests with the reference
standards listed in the section 6.0 “Approval and Certification” allowing more faster construction
times for the new M880 products.
The B014 module is approved for modular devices in the United States (FCC) and Canada (IC).
Modular approval removes the need for expensive RF and antenna design, and allows the end user
to place the B014 module inside a finished product and does not require regulatory testing for an
intentional radiator (RF transmitter).
To maintain conformance, refer to module settings in Annex A.1 for the United States and Annex A.2
for Canada.
The B014 module is an RED Directive assessed radio module for operation in Europe. The module
tests can be applied toward final product certification and Declaration of Conformity (DoC). To
maintain conformance for Europe, refer to module settings in Section ANNEX A.3. Additional testing
may be required depending on the end application.

5.0 Mounting Details
The B014 2.4GHz module is a screw mounting module and layout dimension are shown in figure 3.
The module B014 is 1,6mm (0,063”) thick with castellated mounting point on the edge.
The module was assembled using standard lead free reflow profile for soldering connection. The
module is compatible with standard lead-free solder reflow profiles. To avoid damaging the module,
the following recommendations are given:
• Refer to the solder paste data sheet for specific reflow profile recommendations;
• Use no-clean flux solder paste;
• Do not wash as moisture can be trapped under the shield;
• Use only one flow. If the PCB requires multiple flows, apply the module on the last flow;
The B014 has 50Ω ultra miniature coaxial (U.FL) connector.
Caution: The U.FL connector is fragile and can oly tollerate very
limited number of insertions and disinsertions

A.1 United State
The B014 module
(FCC) CFR47
Telecommunications, Part 15 Subpart C “Intentional Radiators” modular approval in accordance
with Part 15.212 Modular Transmitter approval. Modular approval allows the end user to integrate
the B014 module into a finished product without obtaining subsequent and separate FCC approvals
for intentional radiation, provided no changes or modifications are made to the module circuitry.
Changes or modifications could void the user's authority to operate the equipment. The end user
must comply with all of the instructions provided by the Grantee, which indicate installation and/or
operating conditions necessary for compliance.
The finished product is required to comply with all applicable FCC equipment authorizations
regulations, requirements and equipment functions not associated with the transmitter module
portion. For example, compliance must be demonstrated to regulations for other transmitter
components within the host product; to requirements for unintentional radiators (Part 15 Subpart B
“Unintentional Radiators”), such as digital devices, computer peripherals, radio receivers, etc.; and
to additional authorization requirements for the non-transmitter functions on the transmitter
module (i.e., Verification, or Declaration of Conformity) (e.g., transmitter modules may also contain
digital logic functions) as appropriate.

WARNING:
Changes or modifications made to this equipment not expressly approved by IMET may void the FCC
authorization to operate this equipment.
A.1.2 RF Exposure
All transmitters regulated by FCC must comply with RF exposure requirements.
If appropriate, compliance with exposure guidelines for mobile and unlicensed devices can be
accomplished by the use of warning labels and by providing users with information concerning
minimum separation distances from transmitting structures and proper installation of antennas. The
following statement must be included as a CAUTION statement in manuals and OEM products to
alert users of FCC RF exposure compliance:
To satisfy FCC RF Exposure requirements for mobile and base station transmission devices, a
separation distance of 20 cm or more should be maintained between the antenna of this device and
persons during operation. To ensure compliance, operation at closer than this distance is not
recommended. The antenna(s) used for this transmitter must not be co-located or operating in
conjunction with any other antenna or transmitter.
If the B014 module is used in a portable application (i.e., the antenna is less than 20 cm from
persons during operation), the integrator is responsible for performing Specific Absorption Rate
(SAR) testing in accordance with FCC rules 2.1091.
A.1.3 Approved External Antenna Types
To maintain modular approval in the United States, only the antenna types that have been tested
shall be used. It is permissible to use different antenna manufacturer provided the same antenna
type and antenna gain (equal to or less than) is used.
