In addition, guidelines for the initial installation of the accessories have been included, as well as instructions for setting all the functions and programs of the X-378 to suit your personal preferences. These features are discussed in the same order that they will appear on your radio, as you will see on the accompanying charts. An explanation of the use and purpose of each feature is provided, followed by a labeled illustration of its respective LCD display. In addition, a step-by-step example clarify the setup procedure of the feature. Practical applications for many of the radio’s features enable you to see their true purpose and additional possibilities. A blank data sheet has been included at the end of each section. Once all data has been input for a particular model, it is highly recommended that you record it on a copy of the sheet pr…

February 7, 2002 Federal Communications Commission Equipment Authorization Division, Applications Processing Branch 7435 Oakland Mills Road Columbia, MD 21046 RE) FCC ID: BRWX378 (EA877155) To whom it may concern; Please refer to the additional information listed below while reviewing the BRWX378 System. 1) Section 95.645 (b) states that plug-in crystals must not be accessible to the user. Indicate whether or not crystals are accessible to the user. Although the transmitter crystal is visible from the back of the transmitter, each crystal is glued in place prior to shipment making it a permanent installation. Consumer removal of the crystal will normally result in damage to the crystal. Therefore, frequency changes are done at the service center only. 2) The Manual must contain warnings per section 95.653 A) Please refer to the manual attachment for this information B) All content for operation is contained in the instruction manual. 1) All instructions are contained in the instruction manual. 2) There are no adjustments accessible to the user that would be in violation with the FCC rules. 3) This section is not applicable to our use. If there is any further information required, please contact me directly at: Horizon Hobby Distributors ATTN: Len Sabato Fax: 217-355-0058 Phone: 217-403-3588 [email protected]

This Transmitter is a part of the HORIZON HOBBY DISTRIBUTORS, INC. PPM and PCM "family" of Remote Control Transmitters which at this time consists of: Transmitter Model # FCC ID # XP-642 BRWXP-642 XP662 BRWXP662 Separate Applications for each transmitters and for the receivers are submitted as required by the Commission. The Manufacturer, Japan Remote Control Company (JR), manufactures all transmitters and receivers. The PPM and PCM family of R/C systems is exported by JR to the United States of America, and several European and Asian Countries. The Applicant for this Equipment Authorization, HORIZON HOBBY DISTRIBUTORS, INC. will, following receipt of Grant of Equipment Authorization, import only those versions of these R/C radios which are allowed for use in the USA under the Rules and Regulations of the Federal Communications. The 72 - 73 MHz version of this transmitter is the subject of this Application; these are the units which will be offered for sale to the general public. Page 3 Technical Report Transmitter Model X378 FCC ID# BRWX378 1.2 Application The Model X378 R/C transmitter utilizes " Frequency Modulation" to convey the PPM and PCM encoded position of its control sticks (joysticks) and toggle switches to its companion R/C receiver, where the PPM and PCM encoded pulse train is demodulated, decoded, and supplied to a number of servo-mechanisms for positioning of control surfaces, throttle etc. on the model. The Frequency-Shift-Keying of the transmitter carrier takes place in the rhythm of the PPM and PCM pulse train. Both transmitter and receiver are very narrow band units; they have been designed to comply with the European requirements of 10 KHz channel spacing. 1.3 Construction The Model X378 Transmitter all consists of a plastic case. (Reference is made to Fig. 5.1, Transmitter Block Diagram) * control sticks and control switches * a 9.6V rechargeable (Nicad) battery * an analog-to-digital converter (ADC) * a microprocessor to create the PPM and PCM pulse train (HD6433038TE) * a modulator driver stage * a RF power stage * a telescopic antenna This Transmitter is to be made available by the importer only on those carrier frequencies in the 72 - 73 MHz frequency band which are at present authorized for R/C use. Page 4 Technical Report Transmitter Model X378 FCC ID# BRWX378 2.0 ENCODER THEORY OF OPERATION Reference is made to Figure 5.1, Transmitter Block Diagram. The functions of the encoder are to: * accept the analog voltages from the control inputs (joysticks, toggle switch). * process the analog voltages to create control mixing, adding, reversing, etc., as desired by the user. * sample these voltages in a cyclic rhythm under control of the system's internal timing generator. (This process is called commutation.) * process these analog voltages into binary weighted digital control words by means of an Analog-to-Digital Converter (ADC). * store these digital representations of the analog control input into a temporary memory (RAM). * supply this serial data stream to a buffer-driver for modulation of the RF Transmitter. * provide "housekeeping" of the encoding process by means of a quarts crystal controlled internal clock. * provide supply voltages to the RF section (Vcc = 9.6V battery voltage; Vreg = 6.0V regulated voltage). The entire program which controls the timing housekeeping, parallel-to-serial conversion process, and insertion of synchronization words and error detection codes is governed by a Central Processing Unit (CPU) under control by an internally stored program residing in Read-Only Memory (ROM). The CPU, RAM and ROM are all part of a single-chip microprocessor. Resolution of the Analog-to-Digital conversion process is ten (10) bits for a control accuracy of 1:2 10 Page 5 Technical Report Transmitter Model X378 FCC ID# BRWX378 3.0 THEORY OF OPERATION 3.1 General Reference is made to Figure 5.1, Transmitter Block Diagram. The HORIZON HOBBY DISTRIBUTORS, INC. Model X378 R/C Transmitter is sticks type Transmitter. It operates on any of the R/C frequency (Channels) allowed by the Commission in the 72 -73 MHz frequency band. Selection of the desired RF channel is made by Quarts crystal. This transmitter employs Frequency-Sift-Keying (FSK) of the carrier frequency, whereby the output frequency is either low or high due to the symmetrical FSK modulation process, the (center) output frequency cannot be directly measured, but must be calculated by taking the average of the high and low frequency states. The peak-to-peak deviation of the FSK signal is approximately 3.6 KHz ("sliver modulation") Because of the unfamiliarity of the general public with the term FSK, this modulation technique is commonly named FM. m m m = shift from center frequency m = approx. 1.8 KHz f f f low c high f low + f high f carrier = 2 Page 6 Technical Report Transmitter Model X378 FCC ID# BRWX378 3.2 Block Diagram (Reference is made to Figure 5.1) The (up to) four control potentiometers are at the right side of the schematic drawing.
