T68-FWCSRadio Module

Fluke FWCS Radio Transceiver Module Integration Manual J. Swanzy August 18, 2012 The Fluke wireless communication system (FWCS) radio module is a proprietary IEEE 802.15.4 type low power (< 1mW) radio that is approved for exclusive use in Fluke products. The range of the radio module is specified at 30ft but under ideal conditions my reach 100 ft. The RF packet structure incorporates a point to point proprietary method allowing communication with other Fluke instruments using the same packet structure technique. The radio module is marked with the Fluke internal model number (FWCS). All Fluke products using the radio module must display the FCC and Industry Canada certification number on the outside of an enclosure where it is visible by a user. All radio module settings and protocols are programmed at the time of manufacturing assembly and cannot be modified by a user. The radio module allows Fluke products to work together to collect analog measurement data and pass the data to a central controller (another test and measurement product) for storage and display. The radio module is not intended to be sold commercially or used in products without the Fluke brand. All radio components are mounted on a single 25mm x 10mm PCB. The module contains the transceiver IC (RF transmit and receive), a voltage regulator, and an antenna. The transceiver and regulator circuits are covered by a metal shield soldered to the PCB. The transceiver IC (Texas Instruments CC2530F256) has an RF core that controls the internal radio segments. In addition, it provides an interface between a core 8051 MCU and the other radio circuits. This makes it possible to issue commands, read status, and automate and sequence radio events. The transceiver includes a low noise amplifier, software controlled power amplifier, onboard RF transmit/receive, phase lock loop with internal voltage controlled oscillator, an internal IC power supply regulation, and full spread-spectrum encoding and decoding. The transceiver IC is programmable in 1-MHz steps with 5.0 MHz channel spacing per the 802.15.4 standard. The transceiver IC also includes a packet-filtering and address-recognition capability. The antenna is a 2.45GHz ceramic chip antenna with a peak gain of 3.0dBi. The antenna is the only component that is not mounted under the metal shield. The antenna is a single ceramic chip type and also soldered to the PCB. The radio module is intended to be plugged into a host where the host CPU must communicate to the radio module through a serial peripheral interface (SPI). The SPI provides communication path for receive (RX) and transmit (TX) data transfer and control. The radio module must first be initialized by the host CPU before the transceiver is able to communicate with other Fluke products. The radio will automatically cease operation and thus communication once battery capacity reaches a specified minimum threshold. The module is used in a family of products made by Fluke Corporation and branded Fluke. All radio protocols and module-host communication protocols are Fluke proprietary and not available to the public. Regulatory statements that must be in every User Manual of a Fluke product using the radio module are as follows: FCC Changes or modifications to the wireless 2.4 GHz radio not expressly approved by Fluke Corporation could void the user's authority to operate the equipment. This device complies with Part 15 of the FCC Rules. Operation is subject to the two conditions that follow: 1. This device can not cause interference. 2.

Examples of such devices include, but are not limited to, personal computers, calculators, and equivalent electronic devices that are marketed for operation by the general public. The Meter was 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, can 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 or more of the measures that follow: Reorient or relocate the receiving antenna. Increase the separation between the equipment and receiver. Consult the dealer or an experienced radio/TV technician for help. Exposure to RF Energy THIS MODEL DEVICE MEETS U.S. AND INTERNATIONAL REQUIREMENTS FOR EXPOSURE TO RADIO FREQUENCY RADIATION. The FWCS is a radio transmitter and receiver. It is designed and manufactured not to exceed the emission limits for exposure to radio frequency (RF) energy set by the Federal Communications Commission of the U.S. Government and by the International Commission on Non-Ionizing Radiation Protection (ICNIRP). The device also meets the European Radio and Telecommunications Terminal Equipment (R&TTE) directive, for protecting the health and safety of the user and other persons. These limits are part of comprehensive guidelines that establish permitted levels of RF energy for the general population. The guidelines are based on standards that were developed by independent scientific organizations through periodic and thorough evaluation of scientific studies. The standards include a substantial safety margin designed to assure the safety of all persons, regardless of age and health. Before …

Fluke Corporation Telephone Facsimile Email PO Box 9090 Everett WA 98206.9090 USA 425.347.6100 425.356.5108 http//www.fluke.com Date: August 2, 2012 To: Federal Communications Commission 7435 Oakland Mills Road Columbia, MD 21046 Re: Modular Approval Letter for Fluke FWCS Radio Module To Whom It May Concern: In accordance with Section 15.212 (b), Fluke Corpoartion believes it has met all of the requirements set out in that document for the granting of single modular approval. Specifically, the criteria set out in that document are addressed below in bold: 1. The modular transmitter must have its own RF shielding. This is intended to ensure that the module does not have to rely upon the shielding provided by the device into which it is installed in order for all modular transmitter emissions to comply with Part 15 limits. It is also intended to prevent coupling between the RF circuitry of the module and any wires or circuits in the device into which the module is installed. Such coupling may result in non-compliant operation. The Fluke FWCS radio module has its own shielding covering all critical RF components. This can be seen in the photographs included in the accompanying test report. 2. The modular transmitter must have buffered modulation/data inputs (if such inputs are provided) to ensure that the module will comply with Part 15 requirements under conditions of excessive data rates or over-modulation. The Fluke FWCS radio module has buffered modulation/data inputs provided by the Ti CC2530F128 transceiver IC component. 3. The modular transmitter must have its own power supply regulation. This is intended to ensure that the module will comply with Part 15 requirements regardless of the design of the power supplying circuitry in the device into which the module is installed. The Fluke FWCS radio module incorporates its own supply regulation and the Ti TPS 77028 IC component provides this. 4. The modular transmitter must comply with the antenna requirements of Section 15.203 and 15.204(c). The antenna must either be permanently attached or employ a “unique” antenna coupler (at all connections between the module and the antenna, including the cable). Any Fluke Corporation Telephone Facsimile Email PO Box 9090 Everett WA 98206.9090 USA 425.347.6100 425.356.5108 http//www.fluke.com antenna used with the module must be approved with the module, either at the time of initial authorization or through Class II permissive change. The “professional installation” provision of Section 15.203 may not be applied to modules. The Fluke FWCS radio module employs a “unique” antenna coupler (at all connections between the module and the antenna, including the cable). All antennas have been verified at the time of initial authorization. 5. The modular transmitter must be tested in a stand-alone configuration, i.e., the module must not be inside another device during the testing. This is intended to demonstrate that the module is capable of complying with Part 15 emission limits regardless of the device into which it is eventually installed. Unless the transmitter module will be battery powered, it must comply with the AC line conducted requirements found in Section 15.207. AC or DC power lines and data input/output lines connected to the module must not contain ferrites, unless they will be marketed with the module (see Section 15.27(a)). The length of these lines shall be length typical of actual use or, if that length is unknown, at least 10 centimeters to insure that there is no coupling between the case of the module and supporting equipment. Any accessories, peripherals, or support equipment connected to the module during testing shall be unmodified or commercially available (see Section 15.31(i)). Fluke FWCS radio module was tested with a test jig and Fluke FWCS radio module does not employ any ferrites. 6. The modular transmitter must be labeled with its own FCC ID number, and, 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: “XYZMODEL1” or “Contains FCC ID: XYZMODEL1.” Any similar wording that expresses the same meaning may be used. The Grantee may either provide such a label, an example of which must be included in the application for equipment authorization, or, must provide adequate instructions along with the module which explain this requirement. In the latter case, a copy of these instructions must be included in the application for equipment authorization. The Fluke FWCS radio module is fitted with its own Fluke label and the FCC ID number is enclosure on products that contain the module. 7. The modular transmitter must comply with any specific rule or operating requirements applicable to the transmitter and the manufacturer must provide adequate instructions along with the module to explain any such requirements. A copy of these instructions must be included in the application for equipment authorization. For example, there are very strict operational and timing requirements that must be met before a transmitter is authorized for operation under Section 15.231. For instance, data transmission is prohibited, except for operation Section 15.231(e), in which case there are separate field strength level and timing requirements. Compliance with these requirements must be assured. The modules have been tested to comply with all rules under Part 15.247 The compliance is assured by the design of the device and the user is unable to intervene to cause the device to operate incorrectly.

The limit for Maximum Permissible Exposure (MPE) specified in FCC 1.1310 is followed. The Gain of the antenna used in this product is measured in a Semi-Anechoic Chamber, and also the maximum total power input to the antenna is measured. Through the Friis transmission formula and the maximum gain of the antenna, we can calculate the distance, away from the product, where the limit of MPE is reached. Although the Friis transmission formula is a far field assumption, the calculated result of that is an over- prediction for near field power density. We will take that as the worst case to specify the safety range. 1.1 RF Exposure Limit According to FCC 1.1310 table 1: The criteria listed in the following table shall be used to evaluate the environmental impact of human exposure to radio-frequency (RF) radiation as specified in 1.1307(b) LIMITS FOR MAXIMUM PERMISSIBLE EXPOSURE (MPE) Frequency Range (MHz) Electric Field Strength (V/m) Magnetic Field Strength (A/m) Power Density (mW/cm2) Average Time (minutes) (A)Limits For Occupational / Control Exposures 300 - 1500 ... ...
