- The OBE9141 system allows the connection, by THE ISO-9141 STANDARD means of optical fibers, between an Electronic Control Unit (ECU) on a vehicle and a Diagnostic Tester (DT), according to the ISO-9141 standard.
- The system is composed by an optical transceiver (OBE9141 ECU) interfacing the ECU, placed on the vehicle or near it in the test area and another optical transceiver (OBE9141 DT) interfacing the DT, typically outside the high field test area. The two transducers, both shielded up to 200 V/m over the bandwidth from 10kHz to 18GHz, are connected via three optical fiber cables.
- With three optical fibers the system allows all the communication types described by the standard; for some of the height possible configurations only one or two fibers are needed.
- The two transducers are similar but not identical.
- The OBE9141ECU is powered from the ECU or the vehicle, the OBE9141DT has a dedicated power supply and provides power to the attached DT equipment.
