Part # 9100458 General Description Rosen’s FMT module, part# 9100458 is a 12-channel FM transmitter designed to transmit audio signals over the FM frequency band to enable users to listen to audio from an independent video system over the existing car audio system via the radio. Architectural Overview The FMT transmitter is designed around the BH1417 from Rohm. Refer to the datasheet for details on this part. The module runs off a 5VDC supply, left and right audio signals should be at 1V RMS to achieve maximum volume. A 74HC161 counter is used to control the channel selection of the FM transmitter. The interface to the counter is accomplished by way of a 3-wire communication bus consisting of CLOCK, CLEAR and GROUND lines. A 5V pulse on the CLOCK line will step to the next channel. A 5V pulse on the CLEAR line will reset back to the default channel. FM transmission can be switched on and off by applying and removing the 5VDC supply to the module itself.

Part # 9100458 Operating Guide Using the supplied interface board you are able to test the operation of the FMT. To test your FMT setup as follows: Connect the interface board to the FMT using the supplied 9-pin harness. Connect the power wires on the interface board to a voltage supply between 4.8 & 5.2V DC. The red wire should connect to +ve and black should connect to Gnd. Connect a stereo audio source with a maximum 1V RMS signal to Audio_R and Audio_L connectors. Tune your radio receiver to 88.1Mhz. Audio should be heard. To step to the next FM transmission frequency press the channel select switch located on the interface board once. Re-tune your radio to the next frequency and audio should once again be heard at this frequency. Repeat steps 4 & 5 through all the 12 available FM transmission frequencies. For full details see appendix 1 To stop FM transmission, switch off the +5VDC supply. Interface board wiring diagram Rosen Entertainment Systems LLC 8/30/2005 Rosen FMT. Part # 9100458 Interface / Pinout Definition All control and audio is interfaced via a single connector JP1. It is intended to connect to a control board allowing firmware to control the channels selection as well as the power. See the following table for a pin description and definition: FMT JP1 Pin Definitions Pin # Signal Name Function/Description 1 +5V This is the power to the FMT 2 AR_A Right audio input 3 AL_A Left Audio Input 4 GND FMT Ground Reference 5 Load Not used; held low 6 GND FMT Ground Reference 7 SEL2_A Counter clock; sets the output of the counter 8 SEL1_A Counter Clear; resets the counter to 0 9 ANT Not Used; for test purpose only. Design considerations - The module is intended to interface to a control board that will send the required command to select the desired channel. This can be achieved using a simple push button switch interface however the architecture of the interface enables the interface to be controlled by a micro controller. Ideally you should develop an interface that will provide feedback to the user, possibly by way of an OSD, to indicate which channel the transmitter is currently set to. - In order to disable the FM transmission as well as removing the 5VDC supply, the data lines (SEL2_A, SEL1_A, and Load) should be held low.

Rosen Entertainment Systems FCC ID:TI719295300 Request for Modular Approval Transmitter Module Characteristics per FCC public notice DA 00-1407 requirements Item Requirements EUT 1 Have its own RF Shielding The module has its own shielding. Refer to external photos. 2 Have buffered modulation/data inputs (if such inputs are provided) No such design for this FM transmitter module. 3 Have it own power supply regulation This module does not contain an on-board voltage regulator. The transmitter is specified to operate across a voltage range of +5V +/-0.2volt. 4 Meet the antenna requirements of Section 15.203 The antenna is soldered to the module, no consideration of replacement. Refer to internal photos. 5 Be tested in a stand-alone configuration, i.e., the antenna, AC or DC power and data input/output lines must be connected to the module but, the module must not be inside another case during testing The module was tested outside the host device as stand-alone configuration. Refer to setup photos. 6 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 The module will be labeled with its own FCC ID, and when installed inside another device, the outside of that device will also display a label referring to the enclosed module. 7 The modular transmitter must comply with any specific rule or operating requirements a pplicable 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 under Section 15.231(e), in which case there are separate field strength level and timing requirements. Compliance with The module operates under FCC 15.239. these requirements must be assured. 8 Address compliance with the Commission’s RF exposure limits in Sections 1.1310 and 2.1093. In addition, spread spectrum transmitters operating under Section 15.247 are required to address RF exposure compliance in accordance with Section 15.247(4) Complies with RF exposure limits.
