PCR91502-M Powercast RAIN RFID Reader Module User Manual

PCR91502-M Powercast RAIN RFID Reader Module User Manual

PRODUCT DESCRIPTION

The Powercast PCR91502-M is a RAIN UHF RFID Reader module. The module is intended to be integrated into other electronic product designs in order to enable RAIN RFID functionality. The reader module’s air interface protocol adheres to EPCglobal® UHF Class 1 Gen 2 / ISO 18000- 63 RFID. It is designed to interface to other embedded electronics systems via USB or UART communication lines and is powered from externally applied 5V DC power. The RFID module communicates with and powers RFID tag devices. A Gen2 complian tag device communicates back to the reader via RF backscattering. The reader operates in the 902-928MHz ISM frequency band. Operational power as well as communication is provided to the reader using header J5. The module can support up to 4 antennas via U.FL/UMCC connectors at ports J1 through J4. The PCR91502-M module has on board LEDs to display status of the reader and tag devices.

COMPLIANCE STATEMENTS

This device complies with part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) This device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation.

Changes or modifications not expressly approved by Powercast could void the user’s authority to operate the equipment. Use and maintain device only as specified in this manual.

This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses, and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one of the following measures:

• Reorient or relocate the receiving antenna.
• Increase the separation between the equipment and receiver.
• Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.
• Consult the dealer or an experienced radio/TV technician for help.

WARNING: Operation of the PCR91502-M module requires professional installation to correctly set the TX power for the RF cable and antenna selected.

This transmitter module is authorized to be used in other devices only by OEM integrators under the following conditions:

1. he antenna(s) must be installed such that a minimum separation distance of 23cm is maintained between the radiator (antenna) & user’s/nearby person’s body at all times to meet FCC MPE requirement.
2. The transmitter module must not be co-located with any other antenna or transmitter.

As long as the two conditions above are met, further transmitter testing will not be required. However, the OEM integrator is still responsible for testing the end-product for any additional compliance requirements with this module installed. (i.e., digital device emissions, PC peripheralrequirements, etc.)

IMPORTANT NOTE: In the event that these conditions cannot be met (for certain configurations or co-location with another transmitter), then the FCC authorization is no longer considered valid and the FCC ID number cannot be used on the final product. In these circumstances, the OEM integrator will be responsible for re-evaluating the end product (including the transmitter) and obtaining a separate FCC authorization.

The OEM integrator must be made 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 manual for the end product must include the following information in a prominent location:

USER MANUAL REQUIREMENT

The user manual for the end product must include the following information in a prominent location:

“To comply with FCC’s and IC’s RF radiation exposure requirements, the antenna(s) used for this transmitter must be installed such that a minimum separation distance of 23cm is maintained between the radiator (antenna) & user’s/nearby person’s body at all times and must not be colocated or operating in conjunction with any other antenna or transmitter.”
AND
“The transmitting portion of this device carries with it the following two warnings: “This device complies with Part 15. ..”
AND
“Any changes or modifications to the transmitting module not expressly approved by Powercast could void the user’s authority to operate this equipment”

END PRODUCT LABELING

The end product must be labeled with the following identification information in a visible area: “Contains Transmitter Module FCC ID: YESPCR91502-M” or “Contains FCC ID: YESPCR91502-M

AUTHORIZED ANTENNAS

There are no trace antennas on the PCR91502-M module. This device has been designed to operate with the antennas listed below.

Professional Installation permits the use of the following antennas:

Approved Cables and Adaptors List:

NOTE: Professional installation is required for operation of the PCR91502-M. Only similar antennas with the same or lower gain, and cables with/without additional adapters or connectors with total loss same as or higher than the total loss in the table above can be used to connect to the PCR91502-M without violating FCC regulations. It is the responsibility of the professional installers to comply with this requirement.

FCC MODULAR CERTIFICATION CONSIDERATIONS

Powercast has obtained FCC modular certification for the PCR91502-M module and meets all parts of FCC Part 15.212 and FCC Part 15.247. This means that the module can be installed in different end-use products by another equipment manufacturer with limited or no additional testing or equipment authorization for the transmitter function provided by that specific module. Specifically:

• No additional transmitter-compliance testing is required if the module is operated with one of the antennas listed in the FCC filing.
• No additional transmitter-compliance testing is required if the module is operated with the same type of antenna as listed in the FCC filing, as long as it has equal or lower gain than the antenna listed. Equivalent antennas must be of the same general type (e.g. dipole, circularly polarized patch, etc.), and must have similar in-band and out-of-band characteristics (consult specification sheet for cutoff frequencies).

If the antenna is of a different type or has higher gain than those listed in the modules’ FCC filing, a class II permissive change must be requested from the FCC.

A host using a module component that has a modular grant can:

1. Be marketed and sold with the module built inside that does not have to be end-user accessible/ replaceable, or
2. Be end-user plug-and- play replaceable.

In addition, a host product is required to comply with all applicable FCC equipment authorizations, regulations, requirements and equipment functions not associated with the RFID module portion. For example, compliance must be demonstrated to regulations for other transmitter components within the host product, to requirements for unintentional radiators (Part 15B), and to additional authorization requirements for the non-transmitter functions on the transmitter module (for example, incidental transmissions while in receive mode or radiation due to digital logic functions).

To ensure compliance with all non-transmitter functions, the host manufacturer is responsible for ensuring compliance with the module(s) installed and fully operational. For example, if a host was previously authorized as an unintentional radiator under the Declaration of Conformity procedure without a transmitter certified module and a module is added, the host manufacturer is responsible for ensuring that after the module is installed and operational the host continues to be compliant with Part 15B unintentional radiatorrequirements. Since this may depend on the details of how the module is integrated with the host, we will provide guidance to the host manufacturer for compliance with Part 15B requirements.
