Slaves in the multi-Net
All Leuze barcode readers and decoders that are multiNet plus compatible, can be used as
slaves, e.g. the following devices
• BCL 21 with MA 2
• BCL 31 with MA 2L
• MA 21 100 with hand-held reader
• MA 21 100 with external device
• MA 21 100.2 with RFMx2
• MA 21 100.2 with VRxxxx
Two-wire RS 485
The Leuze multiNet plus is optimised for fast transmission of scanner data to a primary host
computer. Physically it consists of a two-wire RS 485 interface which is controlled by a soft-
ware protocol - the multiNet plus protocol. This makes wiring the network easy and inexpen-
sive since the network wiring is passed through from slave to slave.
For the multiNet shielded, twisted pair conductors should be used. This allows a total
network length of up to 1200 m.
If you would like to operate the MA 21 directly on the host computer, it is also possible to use
the various interfaces (RS 232, RS 422, TTY or RS 485) as well as various protocols such
as 3964/RK512 (not MA 21 100.2).
Protocols
Moreover, various data and frame formats can be selected from the software setup (except
for the MA 21 100.2, see chapter 6.1 "Configuring the interfaces with the BCL-Config soft-
ware"). All standard protocols including 3964/RK512 are thus covered.
