The J1850+ and J1850- pins are used for SAE J1850 communication. For J1850PWM, both J1850+ and J1850- pins are used. For J1850VPW, only the J1850+ pin is used. Despite the presence of physical binding on the J1850+ and J1850- contacts, there is no protocol support in the firmware.Ĭontacts Ring and Sleeve 2.5mm minijack are used to receive data from other devices via the RS-232 protocol. Typically, these are devices such as the Innovate Motorsports wideband oxygen sensor or other MTS bus compatible devices from other manufacturers. The CANL and CANH pins are used for CAN and ISO15765 communication.Ĭontact ISO-9141 K and ISO-9141 L are used for ISO-9141 and KWP2000 communication. Often, only ISO-9141 K line is used. K-line (ISO9141/ISO14230(KWP2000)/dual K line)Ībility to supply voltage for programming and recording logs to a MicroSD card:Īn adapter capable of switching GND or voltage (from 5 to 25 volts) to pins 1,3,9,11,12,13 of the OBD2 connector or an auxiliary 2.5mm stereo connector:Īlso, the adapter’s firmware can record the log received from the 2.5 mm minijack (stereo) connector from Innovate Motorsports devices (lambda probes, etc.) via the MTS data bus protocol to an SD card. Minijack connector (stereo connector) is used to connect an adapter for supplying programming voltage. For example, on Mitsubishi, 18 volts are supplied through it, on Honda 5 volts, etc. (set automatically by a diagnostic program such as Techstream, etc. Since the microcontroller 2364 does not have a built-in SD card controller, work with a MicroSD card designed for recording logs is implemented here via the SPI bus. Support for K / L-line, in this adapter, is made on transistors. It is exceptionally easy to use and requires only two external resistors to set the output voltage). LM317L– voltage regulator 1.25-32 volts (adjustable, positive-voltage regulator capable of supplying 100 mA over an output-voltage range of 1.25 V to 32 V. 6251DS – CAN bus transceiver (transceiver)Ĥ.
