ISO-14230/USB Data Converter
Model 9010

The ISO-14230/USB Data Converter allows a personal computer to act as a diagnostic analyzer during development and testing of an automotive ECU (electronic control unit) that supports the ISO-14230 diagnostic interface. This Data Converter is compatible with Keyword Protocol 2000.


Automotive Data Converters' ISO-14230 Data Converter connects to a personal computer's USB port. It contains a built-in microcontroller that handles ISO-14230 initialization programmable for either 5-baud or fast initialization. Once the connected ECU has been initialized, the Model 9010 Data Converter communicates with the ECU at the programmed baud rate, ranging from 1,000 to 115,200 bps. The ISO-14230 Data Converter optionally supports the L-line, during initialization, as well as the K-line. It contains a programmable load resistor and wide-range power supply, allowing operation at either 12 VDC or 24 VDC in accordance with ISO-14230 specifications.


The ISO-14230 Data Converter comes with a PC program that allows you to initialize a connected ECU, to send messages using the ISO-14230 protocol, and to receive messages. While not a complete ISO-14230 protocol stack, this PC software greatly eases the task of developing and testing a Keyword Protocol 2000 ECU.


The 14230-OBD cable connects the Model 9010 Data Converter to a standard J1962 diagnostic connector.
