Page 22: Operation State
22 | Hardware Description 3.6.2 Operation State The GETK-P4.0A is activated and in operation state. The PCIe links are established and the Ethernet Data Links are available. Configuration, measurement, or firmware updates are possible. Change to the Standby state, if following is detected: - No Wakeup signal from the ECU and - No Ethernet activity at any of the Ethernet interfaces. -
Page 23: Wakeup (Gpio_Wake)
3.7.3 Ready (GPIO_CASC_RDY) A high Ready signal at CAS-IN signals to the ECU, that the GETK-P4.0A is ready and the measurement can be started. If an additional GETK-P4.0A is connected at CAS-OUT, then the Ready signal is only active, if the connected GETK-P4.0A has as well an activated Ready signal. -

GETKs, to extract them and to provide them to the cus- tomer tool for online visualization. The data flow between GETK-P4.0A and RALO Recorder PC and RALO OCRE is con- trolled by the RALO Manager. It provides interfaces enabling the user to configure, to operate and to monitor the RALO Recorder as well as multiple GETKs. -
Page 25: Application Hints
Acquiring Relation between different Clock Domains The GETK-P4.0A is connected to the ECU via PCIe, also it is connected via Ethernet to the RALO systems. The GETK-P4.0A devices are time-synchronized via PTP to the other systems on the Ethernet based measurement network. -
Page 26: Configuration
26 | Hardware Description Solution Regarding the ECU architecture, make sure that the ECU’s memory bandwidth is dimensioned sufficiently, so that the additional read access of the GETK-P4.0A does not significantly increase the memory bandwidth. Restriction If the ECU architecture cannot be dimensioned accordingly, it is recommended to limit the measurement data rate, so that the memory bandwidth is less. -
Page 27: Installation
Take account of different electric potentials in your test setup and take appro- priate measures to prevent equalizing currents. The connectors should be carefully and firmly inserted. ETAS GETK-P4.0A | User Guide... - Page 28 If the PCIe1-5, the 40/100 GE, the 10 GE, and the Power connector are inserted in the correct orientation, they snap in and remain locked. Check, that the connectors remain locked. NOTE The PCIe1-4 connectors are rotated 180° compared to the PCIe5 connector. ETAS GETK-P4.0A | User Guide...
