Device for data transmission switching between different measurement transducer operating modes esp. for position measurement system - transfers data between measurement transducer and processing unit joined by signal transfer lines, device comparing signals on transfer lines with predefined reference signals to identify operating mode

摘要

The device transfers data between a measurement transducer (1) and a processing unit (2) which are joined by one or more signal transfer lines (3,4). The device has a comparison unit (7) which compares the signals on the transfer lines with predefined reference signals to identify the activated operating mode. The measurement transducer can be selectively operated in at least two different operating modes, including at least one measurement mode and at least one programming mode which enables the writing to and read-out from measurement transducer memory regions (6.1,6.2,6.3).
