The MCT245 is designed for mobile applications in accordance to Part 2.1091(b). The MCT245 remote control products are assembled by Kar- Tech, at Kar-Tech. There are no user serviceable parts on the MCT245 transceiver. The MCT245 is not designed for multiple antenna applications and should not be used to transmit simultaneously with any other transmitter. OPERATION The MCT245 is a radio Receiver product for the 2.4 GHz ISM bands. The Receiver microcontroller includes a CPU, GPI/O, a fully integrated frequency synthesizer, a power amplifier, a modulator and a receiver unit. The data received from antenna is sent to the microcontroller for processing. The MCT245 microcontroller monitors the input data, received data and controls outputs. The system data is sent to the RF processor and then to RF circuit, and then to the antenna. The microcontroller is responsible for the control of the entire communication. The MCT245 transceiver contains a DC regulator which generates a constant 1.8 VDC for the digital MCT245 RECEIVER 3 circuitry. The RF section runs on the 3.3V supply. The MCT245 uses Frequency Hopping Spread Spectrum that uses 16 channels for any hop mode, between 2.407GHZ and 2.470GHZ, with 1MHZ resolution. The receivers are matched to the transmitters to use the same channels and sequence as the transmitter’s signals. The MCT245 controls outputs which can operate relays, hydraulic valves, lights, or other similar load devices, according to customer requirements. Where Used Typical applications for the MCT245 are to controlling valves, relays and lights on agricultural equipment, construction equipment, and other similar equipment. MCT245 RECEIVER 4 INSTALLATION 1) Attach the external harness to the MCT245. 2) Assemble the MCT245 assembly into the Enclosure. 3) Place a label on the outside of the enclosure on the side.

B) Assemble the MCT245, into a KAR-TECH Receiver enclosure. C) The MCT245 is to be installed only in mobile applications. See Part 2.1091 for definitions of mobile and fixed applications. D) Do not operate the MCT245 without an antenna. E)Documentations: In the host’s User Manual include the following: a. That there are no user serviceable parts in the radio product. 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 only configurations in which the antennas used for this transmitter must be installed to provide a separation distance of at least 20cm from all person and not be co- located with any other transmitters except in accordance with FCC and Industry Canada multi-transmitter product procedures.” BEFORE APPLYING POWER! Check power and ground for proper polarity. MCT245 RECEIVER 6 Read the rest of this manual. TROUBLESHOOTING There are no user serviceable parts in the MCT245 Receiver. Contact your KAR-TECH representative for further instructions or servicing. PARTS LIST PART NUMBER DESCRIPTION 022081A MCT245 RADIO TRANSCEIVER – REMOVEABLE ANTENNA There are no user-serviceable parts inside the transmitter or the receiver. Return the units for service.

Introduction The MCT245 is a direct sequence spread spectrum transceiver product designed to be compatible wit h US (FCC Part 15.247) and Canadian (RSS-210) regulations for license free use in the 2.4GHz IS M band . The MCT245 trans ceiver is a stand-alone Kar-Tech remot e cont rol product. Theory of Operation The MCT245 is a radio transceiver product for the 2.4GHz 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 MCT245 is primarily a receiver that communicates with a transmitter bidirectionally in a half-duplex fashion. The data received from antenna is sent to the RF microcontroller. The microcontroller takes the RF data to control outputs. The microcontroller also monitors input signals from local inputs. This data is sent to the RF processor and then is sent from the RF processor to RF circuit, and then to the antenna. The microcontroller is responsible for the control of the entire communication. The MCT245 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 receivers are matched to the transmitters to use the same channels and sequence as the transmitter’s signals.
