2.1
Differences between MA 30 / MA 31
With regard to their function as network masters, both connector units MA 30
and MA 31 (referred to simply as MA 30/31 in the following) are identical.
The connection provided on the MA 30 can be used to connect a scanner of
the BCL 40 or BCL 80 family. The MA 31 is not provided with this connection.
The overall height of the MA 31 is, thus, lower ("chapter 2.8 "Dimensioned
drawings").
2.2
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.
The MA 30/31 can control up to 30 slaves in a network and can output the
read data to a common host interface.
When used in combination with a bar code reader BCL 40/ BCL 80 (referred
to in the following as BCL xx), the MA 30 is a fully functional reading station,
so that 31 stations can be combined into a network.
