ISO-14230/RS-232 Data Converter
Model 9002

The ISO-14230 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.


The ISO-14230 Data Converter connects to a personal computer over an RS-232 serial link running at the standard PC baud rate of 19,200 bps. 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 ISO-14230 Data Converter communicates with the ECU at 10,400 bps, and with the PC at 19,200 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.


Automotive Data Converters' 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 9002 converter to a standard J1962 diagnostic connector.
