+3.0dBi.The antenna is permanently connected to the radio on the module. No other antennas are approved for use with this module. 5 Installation Guidelines The EMR303 radio module is only available for use in Emerson products. Host integrators must consult with the manufacturer for specific pinout assignments for data and power. Host integrators must perform required testing to ensure compliance with host product regulations. This section describes the test modes needed for spectrum approvals. To access these test modes, special host test firmware must be loaded. 5.1 Spectrum Approval Test Modes Spectrum approval test modes are accessed via serial commands using TIs BTool software. Btool version 1.42.19 must be used. UART connections are available on pins 5 and 6 of the module. USB to UART serial converters from FTDI are recommended (TTL-232RG). Be sure to choose the correct voltage cable that matches with your supply voltage to the BLE module. These test modes are not accessible by the general public. 5.1.1 Bluetooth Tests Radio testing for Bluetooth is performed as both radiated and/or conducted testing. The conducted tests require a Murata RF probe be connected to the BLE module (P/N MXHQ87WA3000) and routed to the labs test equipment. Transmit tests require the following BTool commands and runs at 100% duty cycle:

HCIExt_SetTxPowerCmd Set transmit power to +5dBm HCIExt_EnhancedModemTestTxCm Set PHY mode (1M or 2M) and RF channel to be tested. HCIExt_EndModemTestCmd Select this to change RF channels, PHY modes, or when the test is complete. Receive tests require the following BTool command:

Page | 4 HCIExtModemTestRxCmd Place the module into receive mode for Receiver Spurious Emissions. Select channel to be tested (usually channels 0 and 39). EMR303 Integration Guide 6 Regulatory and Standards Compliance The EMR303 allows modular host product integration in the United States, Canada, and European Union.

Application Examiner Re: Justification of Modular Approval Applicant: Rosemount Inc. FCC ID: LW2-EMR303 Dear Application Examiner:

Modular Transmitter Model EMR303, FCC ID:LW2-EMR303, Request is hereby submitted by Rosemount, Inc. to certify the Bluetooth Low Energy Radio Module EMR303 as a Single Modular Transmitter under the FCC rules CFR47 Part 15.212. The following list shows compliance with each of the special requirements listed for modular approvals:

1. The modular transmitter must have its own RF shielding. The radio has a metal enclosure as can be seen in the photos. 2. The modular transmitter must have buffered modulation/data inputs. The module uses the TI CC2642R radio chip and it has buffered input and outputs. 3. The modular transmitter must have its own power supply regulation. The TI CC2642R has built in voltage regulation. 4. The modular transmitter must comply with the antenna requirements of Section 15.203 and 15.204(c). The module contains an integrated PCB trace antenna and has no external connection for other antennas. The antenna is permanently attached and cannot be modified by the end user. 5. The modular transmitter must be tested in a stand-alone configuration. The EUT was tested in a stand-alone configuration as demonstrated in the test report. 6. The modular transmitter must be labeled with its own FCC ID number. Per the FCC ID label and location exhibit, the FCC ID is permanently affixed to the module. If the FCC ID number will not be visible when the module is installed inside a host device, another label with the FCC ID will be applied to the exterior of the host device. 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. See the test report and the user manual with the integration instructions. 8. The modular transmitter must comply with any applicable RF exposure requirements. The EUT is compliant with all applicable RF exposure requirements. Please see RF Exposure Exhibit. Sincerely, Elizabeth Reierson Quality Engineer Rosemount Inc.

FCC ID: LW2-EMR303 To whom it may concern, Permanent Confidentiality Request is hereby submitted by Rosemount, Inc. to withhold permanently from public review certain portions of the application for equipment certification for the referenced FCC identifiers. This request for confidentiality is made pursuant to 47 CFR 0.457(d) and 0.459 of the FCC Rules. In particular, the following sections of the application are to be kept permanently confidential:

Schematics Detailed Block diagrams Operational/Functional Description Bill of Materials/Parts List This device is a non-consumer device inaccessible to general public and is only accessable by qualified technical personnel in the industrial control industry. Rationale for request for confidentiality:

Rosemount Inc. has invested considerable time and materials in research and development to produce the referenced product. Disclosure of the permanently confidential portions of this application to competitors would not only give them significant competitive advantages in developing similar products, but would also disclose successful implementation of unpublished, leading-edge technology developed by Rosemount.
