RB9500 Designer’s Guide (01-30-16) 3 Introduction Thank you for choosing Radicom RB9500Module. We are committed to providing you quality service and technical support. The RB9500modules are designed to meet OEM’s needs of embedding short-range, low power, wireless data connectivity to their products. The RB9500offers a quick and simple solution for wireless 2.4GHz FSK/GFSK Transceiver. The RB9500 module is designed for 2.4GHz ISM band wireless applications. The module integrates both high sensitivity receiver (- 95dBm @ 500Kbps) and high efficiency power amplifier (up to 1dBm). In low data rate application, RB9500has special strength for long LOS (line-of-sight) distance because of its ultra high sensitivity (-107 dBm @ 2Kbps, - 104 dBm @ 25Kbps) with no requirement of external LNA or PA. Based on Data Rate Register (0x0E), user can configure on-air data rates from 2Kbps to 500Kbps. The RB9500module supports fast settling time (130 us) for frequency hopping system. For packet handling, the RB9500 has built-in separated 64-bytes TX/RX FIFO (could be extended to 256 bytes) for data buffering and burst transmission, CRC for error detection, FEC for 1-bit data correction per code word, RSSI for clear channel assessment, data whitening for data encryption / decryption. For power saving, RB9500supports sleep mode, idle mode, standby mode. For easy-to-use, RB9500has an unique SPI command set to control internal state machine. Based on the command set via SPI bus, MCU can control everything from power saving, TX delivery, RX receiving, channel monitoring, frequency hopping to auto calibrations. In addition, RB9500supports two general purpose I/O pins, GIO1 and GIO2, to inform MCU its status so that MCU could use either polling or interrupt scheme to do radio control. Hence, it is very easy to monitor radio transmission between MCU and RB9500via digital interface. Important Information about FCC, IC, CE Certification RB9500 series is using 2.4GHz ISM band with non-standard protocol for transmitting power, timing, cadence and modulation. Therefore, any firmware involved to change those parameters will affect to FCC/IC/CE Certification.

RB9500 Designer’s Guide (01-30-16) 12 Layout Design Suggestions • General Layout Rules- All Printed Circuit Boards must comply with UL94V0 standard for flammability. Always use RoHS compliant Parts and materials. • Suggestions for Layout: 1. Do not place Power circuit, X’tal, Inductor, etc near RF area. 2. The bigger Antenna clearance area, the better. The Antenna itself needs to stay away from any circuit or component at least 3mm. Antenna clearance area means Top and Bottom both required to be cleared. 3. Do not use metal materials on design where near Antenna area. For example, battery snaps, USB connector, iron case, etc. These guidelines are for design reference; real performance still depends on actual design.

MCU can access those control registers via 3-wire (SCS, SCK, SDIO) or 4-wire (SCS, SCK, SDIO, GIO1/GIO2) SPI interface (support max. SPI data rate up to 10 Mbps). RB9500is simply controlled by registers and outputs its status to MCU by GIO1 and GIO2 pins. See datasheet for the details.
RB9500 Designer’s Guide (01-30-16) 19 FCC & IC Label and Model Identification The RB9500 module family is FCC Part 15 and IC (Industry Canada) certified. The RB9500 is also CE marked. The modules are labeled with the RB9500 module model number and FCC Part 15 ID, IC registration number and CE mark. The label can be found on top of the metal shielding on the RB9500 Module.
RB9500 Designer’s Guide (01-30-16) 20 Note: Models RB9500 will have an additional Product ID label containing the HM model number.
RB9500 Designer’s Guide (01-30-16) 21 Important Regulatory Compliance and User Information The final product with the modules installed needs to be tested for FCC Part 15, IC (Industry Canada) CE, EMI/RFI compliance. Radicom certification documentation will help streamline the final product approval process. Contact Radicom for more information. To maintain compliance in the finished product, carefully follow guidelines in this section. This device is intended only for OEM integrators under the following condition: The transmitter module may not be co-located with any other transmitter or antenna. As long as this condition is met, further transmitter testing will not be required. However, the OEM integrator is still responsible for testing their end product for any additional compliance requirements required with the module installed (for example, digital device emissions, PC peripheral requirements, etc). IMPORTANT NOTE: In the event that this condition cannot be met then the FCC authorization is no longer considered valid and the FCC ID 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. Host (End Product) Labeling Requirements The final end product must be labeled in a visible area with the following: " Contains TX FCC ID: K7T-RB9500 ". RB9500 is for the model of the module used in the end equipment. The label shall be securely affixed to a permanently attached part of the device, in a location where it is visible or easily accessible to the user, and shall not be readily detachable. The label shall be sufficiently durable to remain fully legible and intact on the device in all normal conditions of use throughout the device’s expected lifetime. These requirements may be met either by a separate label or nameplate permanently attached to the device or by permanently imprinting or impressing the label directly onto the device. The label text shall be legible without the aid of magnification, but is not required to be larger than 8-point font size. End User Information
