MCT247 2.4GHz MODULAR TRANSCEIVER OEM INSTALLATION AND OPERATION MANUAL NOTE: THIS MODULE IS LIMITED TO OEM INSTALLATION ONLY July 27, 2020 HK/TH MCT247 TRANSCEIVER 1 INDEX DESCRIPTION ........................................................................... 2 OPERATION .............................................................................. 3 INSTALLATION ......................................................................... 4 BEFORE APPLYING POWER! ...................................................... 6 TROUBLESHOOTING ................................................................. 6 TRANSCEIVER PICTORIAL ........................................................ 6 SPECIFICATIONS ...................................................................... 8 INSTRUCTION TO THE USER ..................................................... 9 INDUSTRY CANADA STATEMENTS ........................................... 10 MCT247 TRANSCEIVER 2 DESCRIPTION The MCT247 is a frequency hopping spread spectrum transceiver module designed to be compatible with US (FCC CFR 47 Part 15 C (15.247)), Canadian (RSS-210), EU(RSS- 247 Issue 2/RSS-GEN Issue 5/ANSI C63.10:2013, IEC 62368-1:2014 (Second Edition)) and Australian() regulations for license free use in the 2.4 GHz ISM band from 2.407GHz to 2.470GHz. The MCT247 is designed for mobile and portable applications in accordance to Part 2.1091(b). The MCT247 complies with ISED Limit per RSS-102 Issue 5 for the uncontrolled RF Exposure of portable device. The MCT247 transceiver is only integrated into Kar-Tech remote control products by Kar-Tech, at Kar-Tech. There are no user serviceable parts on the MCT247 transceiver. The MCT247 is not for sale by itself. The MCT247 is not designed for multiple antenna applications and should not be used to transmit simultaneously with any other transmitter. The MCT247 is only certified to use the integrated wire antenna. If the OEM or other user requires further compliance beyond those listed above, the OEM or User is responsible for attaining such additional certifications. MCT247 TRANSCEIVER 3 OPERATION The MCT247 is a radio transceiver module for the 2.4 GHz ISM bands. The transceiver microcontroller includes a CPU, GPI/O, a fully integrated frequency synthesizer, a power amplifier, a modulator and a receiver unit. The MCT247 microcontroller serial port is connected to the host via protection circuits. The data is sent through a serial port to RF processor and then to RF circuit to the antenna and the data received from antenna is sent to the serial port and to the host. The microcontroller is responsible for the control of the entire communication. The MCT247 transceiver contains a DC regulator which generates a constant 1.8 VDC for the digital circuitry. The RF section runs on the 3.3V supply. The MCT247 uses Frequency Hopping Spread Spectrum, that uses 16 channels, between 2.407GHZ and 2.470GHZ with a 1MHz resolution. The receivers are matched to the transmitters to use the same channels and sequence as the transmitter’s signals. There are no test modes built in to the MCT247. Host code is to be used to ensure compliance. MCT247 TRANSCEIVER 4 INSTALLATION 1) Solder the MCT247 transceiver directly to the host’s compatible connector. 2) Print and attach the label as shown below: 3) Place a label on the outside of the host enclosure in a visible area. On the label, include the following: “Contains FCC ID: P4U- MCT247” and “Contains IC: 4534A-MCT247” 4) Connect the appropriate antenna. A ¼ wavelength wire antenna. 5) Once integrated into a final product, use a spectrum analyzer to make sure the product still complies. Look for: a. Peak Power < 20dBm b. Other peaks above 1GHz should be < 74dBuv/m. Below 1GHz, they should be < 40dBuV/m. MCT247 TRANSCEIVER 5 Application Requirements: A) Power the MCT247 Transceiver with 3.3VDC nominal voltage, with peak current draw of 150mA. B) Do not remove the shield on the MCT247. C) If you use something other than the wire antenna, the unit needs separate approval. D) The MCT247 can be installed in mobile or portable applications. See Part 2.1091 for definitions of mobile, portable and fixed applications. E)Do not operate the MCT247 without an antenna. F) Documentations: In the host’s User Manual include the following: a. That there are no user serviceable parts in the radio modules. They should not remove or install radio modules. b. The “Instructions To The User” section. c. The “Industry Canada Statement”. d. Include in the manual, “This device is granted for use in Mobile and Portable configurations, with no restrictions on antenna placement for exposure purposes.” MCT247 TRANSCEIVER 6 BEFORE APPLYING POWER! Check power and ground for proper polarity. Read the rest of this manual. TROUBLESHOOTING There are no user serviceable parts in the MCT247 Transceiver. Contact your KAR- TECH representative for further instructions or servicing. PARTS LIST PART NUMBER DESCRIPTION 021535C MCT247 RADIO TRANSCEIVER – WIRE ANTENNA There are no user-serviceable parts inside the transmitter or the receiver. Return the units for service.
