    Function of the MA 30/31 General Information The modular connector units MA 30/31 serve as masters in the Leuze multi- Net plus network. In addition to its function as a network controller, the MA 30 is also an intelligent connection and switching box for the bar code reader BCL 40/80.
  • Page 6 Device Description Slaves in the multiNet All Leuze bar code readers and decoders which are capable of multiNet plus can be used as slaves; these are the devices • BCL 40/BCL 80 with MA 10 • BCL 41 with MA 3-3000 •...

  • Page 7: Addressing In The Network

    Leuze uses 2-byte ASCII addressing in multiNet plus. This addressing is included in each data telegram. This address must be selected at the stations either via hardware (rotary switch) or via software.

  • Page 16: Connection

    The pin assignment of the connection terminals is dependent on which interface module is plugged in. Interface module pin Leuze offers four modules which establish an electrical connection to the assignment serial interfaces RS 232, RS 422, TTY or RS 485. The terminal designations are printed on the module.

    To do this, use the service interface of the MA 30/31 and switch to "service network" (see chapter 2.6 "Service mode"). Using the CONFIG 3.0 configuration software, you can make the changes to the host interface off-line, and then download them to the MA 30/31. Leuze electronic Connector Unit MA 30 / MA 31...

  • Page 29: Executing A Reset

    Attention! A cold start replaces the current parameter set either with your customer-spe- cific parameter set or the Leuze factory parameter set, i.e. any settings made there are lost. Therefore, perform a hardware RESET only when the software cannot be started or when you intentionally want to reset the MA 30/31 (and the BCL xx connected to the MA 30).
