ELM327 v1.4b

The ELM327 has been improved once again, with more error checking, code improvements, and of course, new features.

• Power Control provides a very low power standby mode
• More J1939 support
• A non-volatile memory location for storing user data
• An option to turn off the CAN silent monitoring for bench testing, or when connecting to a dedicated CAN port
• CAN extended addressing support for experimenting with special data formats
• The ISO/KWP bus initializations may now be performed without having to send a request
• A 4800 baud ISO option, to compliment the 10400 and 9600 rates
• An SS command for searching sequentially through the protocols
• A TA command to change the Tester Address without using a PP
• The ability to quickly restore the factory calibration for the voltage reading circuit

This is a multi protocol IC. It combines the ELM320, ELM322 and ELM323 into one IC, also adds CAN support (ISO 15765-4) as well.

• RS232 baud rates to 500 Kbps
• Adaptive Timing automatically adjusts ST timeouts
• Power up to AT MA is selectable
• Source (tester) address can be changed
• Can reset all PPs with a jumper
• Receive addresses can be independently set
• Supports J1850 VPW and PWM, ISO 9141-2, ISO 14230-4 as well as ISO 15765-4.
• Uses the same simple ascii command interface.
• Internal EEPROM can remember the last protocol.
• Voltage input monitors your vehicle battery.
• The slow initiation address can now be varied
• Control over key word checking
• KWP protocols can now transmit 3 or 4 byte headers
• New J1939 protocol
• Two user-definable CAN protocols
• Improved error handling and recovery
