Rationale: Revised based on feedback from suppliers making production versions. 1 Changes meet the new EMC standard IEC 62132-4. 2 Addition of an optional pause pulse 3 Defining a new enhanced serial message as an optional replacement for the original short serial data message 4 Clarifying the diagnostics and remedial actions for successive calibration pulses comparisons 5 Added recommended modification to 4-bit checksum calculation. Recommended checksum calculation includes processing a zero nibble in addition to the data nibbles to protect for common error in last data nibble and checksum. The original CRC method is retained as an option for designs already in process or production that were developed according to previous SENT norms. 6 Added new recommended circuit topology to better handle 3.3V systems. All new sensors should use the recommended topology. The original topology is retained as an option for designs already in process or production that were developed according to previous SENT norms. 7 Added configuration shorthand notation 8 Updated MAF, Temperature and Pressure applications to take advantage of the new Enhanced Serial Message 9 Added EMC Susceptibility testing guidelines 10 Added reset action by transmitter 11 Changes for clarifications or to address typos.
