RFI341 Radio Frequency Interrogator

5.3 Electrical Connections (M12 connectivity version)

The M12 Connectivity Version consist out of one PG plug for e.g. Ethernet

and M12 plugs for power, RS232, Output and 2 for the Trigger Input. The

individual pinning could be found on a sticker that is placed inside the device

door.

5.4 Preparations for Electrical Installation

5.4.1 Requirements for the RS-232 HOST interface

The host interface can be operated as a RS 232 data interface. The

maximum cable lengths are a function of the selected data transfer rate:

To prevent interference, do not lay the cable parallel to the mains supply and

motor cables over long distances, e.g., in cable ducts.

5.4.2 Requirements for the Profi-Bus interface

The Bus termination is realised with 3 resistors mounted at the terminals. If a

device is not the last station in a Profi-Bus network those resistors have to be

removed. The shielding need to be fixed with the available shielding

brackets at the PG glands.
