    Data Recorder Type DTI375.TH-5% 2. Installation and operation 2.1 Installation and operation From the point of view of DTI technology (Digital Trans-du- cer Interface), the data recorder of the Type DTI375.TH- 5% (see Fig. 1) represents the core element in the field of in-dummy measurement data acquisition and is designed for direct installation in the crash test dummies/ATDs (An- thropomorphic Test Devices).

  • Page 9: Mounting The Type Dti 375.Th-5% In The Dummy

    Installation and operation Each DTI port has an individual RS-485 transceiver for the data transfer on the bus. This setup is very robust against interferences and emits only very low interferen-ces itself, which means that the achieved signal quality is better than conventional analog technology.

    Installation and operation 2.4.5 Trigger features 2.4.5.1 Digital trigger The DTI375.TH-5% has two digital trigger signals (T0 and SR) each connected through the main system connector using an RS-485 bus. The signal can be generated by an RS-422 or RS-485 driver.

  • Page 22: Other Trigger Possibilities

    Data Recorder Type DTI375.TH-5% 2.4.5.3 Other trigger possibilities Software trigger for start record: You may activate a soft- ware SR trigger. With the software SR trigger the data acquisition will start immediately. All other connected DTI375.TH-5% systems may see this SR trigger at the same time since it can also be distribut- ed on the dummy system cable, when activated.
  • Page 23 Installation and operation After the T0 event, the recorder will continue to write measurement data into the flash memory of the DTI375 recorder and will automatically stop after the configured post-trigger time (DELAY in Fig. 10). It is guaranteed that no data after the T0 event is overwritten.

  • Page 25: How To Estimate The Acquisition Time

    Installation and operation 2.5 How to estimate the acquisition time Since the DTI375.TH-5% consists of two independent re- corder subunits, the recording time of the overall system depends on the recorder subunit with the most occupied channels. In order to maximize the overall recording time of the Type DTI375.TH-5% data recorder it is recommended to distribute the sensors equally across DTI ports 1 ...
