RFI341 Radio Frequency Interrogator

5.4.5 Connecting the “Input 1” Switching Input

If a reading procedure of the RFI341 shall be triggered by an external

sensor, then the reading pulse sensor must be connected, e.g., to the Input 1

switching input. The triggering feature is set by the background function as

described in the document “Telegram Listing RFI341”. The GND1 is

galvanically separated. Therefore the reference for the Input 1 level must be

provided by the customer. OK1 not assembled.
