Introduction Thank you for purchasing Radicom Research’s RB4000 Bluetooth Module. We are committed to providing you quality service and technical support. The RB4000 and RB4000HM Bluetooth modules are designed to meet OEM’s needs of embedding short- range wireless data connectivity to their products. The RB4000 family offers a quick and simple solution for wireless point-to-point Bluetooth communications. The RB4000 series are Class 2 Bluetooth modules using BlueCore4-External Chipset from CSR, the leader in Bluetooth chipsets. These embedded modules are Bluetooth V.2.0 + EDR (Enhanced Data Rate) compliant that increase throughput, reduce battery consumption and improve security. It provides faster pairing and allows superior performance in the presence of interference from 802.11 WiFi wireless devices and other 2.4GHz radios. The RB4000 series has 8Mbits flash memory on board for upgrading the modules firmware. OEM specific parameters and settings can be loaded into these modules. Radicom can modify the firmware to meet OEM requirements and create custom Bluetooth functionality to meet your specific needs. The RB4000 Series supports Serial Port Profile functionality for setting up virtual serial ports on two devices (e.g. PCs) and connecting the two devices using the RB4000 Bluetooth modules to emulate a RS232 serial cable between the two devices. There are 4 models available, RB4000, H4000CE, RB4000HM-a, and RB4000HM-c. The RB4000 and H4000CE are surface mount PCB Bluetooth modules with on-board antenna. The RB4000 and H4000CE are identical except for the name that was changed for marketing reasons. The RB4000HM-a is serial through-hole Bluetooth module with an on board antenna. The RB4000HM-c is serial through-hole Bluetooth module with an U.FL connector for an external antenna to provide the flexibility for placing antennas in a desired location. For evaluation purposes we offer kits for both the onboard and external antenna versions of the modules. Each kit will include one each SPP-A Initiator and SPP- B Acceptor Bluetooth module installed into carrier boards with a RS232 Serial connector. Upon receipt of the Evaluation kits, the user can immediately connect the carrier boards to any standard serial port to evaluate the Bluetooth modules. 3 Features • Bluetooth 2.0+EDR support • Small sizes: 0.57” x 1.26” x 0.08” (RB4000) or 1” x 1.26” x 0.2” (RB4000HM) • Class 2 radio, 4dBm transmission power • Serial Port Profile (SPP) support • Secure simple pairing support • Link Data Rate 2.1Mbps Max • SPP/ UART data rates: 115.2Kbps • GAP (Generic Access Protocol) • SDP (Service Discovery Protocol) • L2CAP (Logical link control and adaptation protocol) • RFCOMM embedded stack profiles support • 8Mbits flash memory on board • Secure communications with 128-bit encryption • Onboard antenna or with an U.FL connector for external antenna • Supports 802.11 wireless co-existence • Custom application specific Firmware is possible.

RF Antenna Conducted Spurious test 8.1 Operating environment Temperature: 25 °C Relative Humidity: 58 % 8.2 Test setup & procedure The test procedure was according to FCC measurement guidelines DA 00-705. The measurements were performed from 30MHz to 25GHz RF antenna conducted per FCC 15.247 (c) was measured from the EUT antenna port using a 50ohm spectrum analyzer with the resolution bandwidth set at 100 kHz, and the video bandwidth set at 100 kHz. Harmonics and spurious noise must be at least 20dB down from the highest emission level within the authorized band as measured with a 100 kHz RBW. The table below is the results from the highest emission for each channel within the authorized band. This table was used to determine the spurious limits for each channel. 8.3 Measured data of the highest RF Antenna Conducted Spurious test result The test results please see the plot below. FCC ID.

The Diagram below shows the test setup, which is utilized to make these measurements. The frequency spectrum from 30MHz to 1000MHz was investigated. RF Test Receiver 0.8 m EUT & Peripherals Ground Plane Antenna Tower Receiver Antenna 1.0~4.0 m 3 m □ FCC ID. K7T-RB4000 Report No.: TS12010105-EME Page 39 of 68 The frequency spectrum from over 1GHz was investigated. The signal is maximized through rotation and placement in the three orthogonal axes. Radiated emission measurements were performed from 30 MHz to 25 GHz. Spectrum Analyzer Resolution Bandwidth is 100 kHz or greater for frequencies 30 MHz to 1 GHz, 1MHz – for frequencies above 1 GHz. The EUT for testing is arranged on a fiberglass turntable. If some peripherals apply to the EUT, the peripherals will be connected to EUT and the whole system. During the test, all cables were arranged to produce worst-case emissions. The signal is maximized through rotation. The height of antenna and polarization is changing constantly for exploring for maximum signal level. The height of antenna can be up to 4 meters and down to 1 meter. The measurement for radiated emission will be done at the distance of three meters unless the signal level is too low to measure at that distance. In the case of the reading under noise floor, a pre-amplifier is used and/or the test is conducted at a closer distance. And then all readings are extrapolated back to the equivalent 3 meter reading using inverse scaling with distance.
