A9 Serial Interfaces

______

A9 Serial Interface

The A9 ECU Interface product is a high-speed ECU interface that efficiently communicates to an ECU over the processor’s DAP interface. To use the A9, a simple plug-and-play gigabit Ethernet interface can be connected directly to a PC or standard LAN, eliminating any need for expensive interface boxes. Hardware IEEE-1588 PTP time synchronization ensures accurate correlation to other acquired data

Product Features:
  • Calibrate, DAQ, and Flash ECUs with a single product
  • Wide -40 to +105°C operating temperature range
  • Automotive surge tolerant wide operating voltage of 5 to 36VDC
  • Plug and play direct Ethernet connection to PC
  • 1Gbps Ethernet w/IEEE-1588 PTP time sync
  • ECU cold start capability for instantaneous data acquisition at ECU power-up
  • Dynamic data rates allow real-time reconfiguration of acquired data items
  • Support for 125,000 unique data items
  • Any DAQ item addressable within the ECU
  • DAP interface up to 160MHz with auto-sense speed and multiphase receive
  • Read data from and write data directly to the ECU processor’s memory
  • Capable of supporting ECUs from most OEMs
