ASAP 3 and VISION

Through ATI’s VISION ECU Calibration, Data Acquisition and Diagnostics software, an ASAP 3 host can be set up to remotely control devices for automated tests using the ASAP 3 communication protocol. This remote-control capability is advantageous for engineers who need to access specific items during acquisition.


Created by ASAM (the Association for Standardization of Automation and Measuring Systems) ASAP 3 defines an RS232 communication protocol between a test automation system and a measurement and calibration system connected to an ECU.


Several reasons drive the extensive use of ASAP 3. Primarily ASAP 3 provides a standardized protocol for communication between calibration tools and ECUs, ensuring seamless interoperability between tools and ECUs from various manufacturers.


Efficiency is crucial during the development and calibration phases of automotive electronic systems. The protocol is designed for high-speed communication, enabling faster data exchange between calibration tools and ECUs.


Flexibility makes ASAP 3 suitable for a wide range of applications in the automotive industry, supporting various automated measurement and calibration tasks such as adjusting parameters, measuring data, and flashing ECUs.

Compatibility, as a widely adopted standard, ensures high levels of interoperability between various calibration tools and ECUs from different vendors. This is particularly important in the automotive industry, where multiple suppliers frequently contribute difference components to a single development vehicle or powertrain.


ASAP 3 enhances the reliability of the calibration process. Engineers can trust that the communication between tools and ECUs follow a well-defined and tested standard, reducing the risk of errors or inconsistencies.


The benchmark of the ASAP 3 standard contributes to cost saving in the development process by minimizing the need for custom interfaces and special adaptations for each tool-ECU pair.


Now developed as ASAP 3 V3.0, the latest iteration maintains backward compatibility with previous versions (V2.0, V2.1, and V2.1.1). Notably, previous V2.1 versions lacked documentation or implementation of Diagnostics functionality. In the context of ATI’s VISION software, the ASAM ASAP 3 interface actively listens for commands transmitted by the Automation System (AuSy) through a serial link (RS232) or Ethernet port. Although Ethernet connection is not officially part of the standard, it can be utilized for test implementations.


ASAP 3’s core features within VISION cover online analysis, offline analysis, data management, printer functions and ECU flashing. ATI’s VISION includes comprehensive documentation, demonstrating the interpretation of ASAP 3 requests alongside proprietary commands, ensuring clarity and ease of use.
