Functions of the MA 21
General information
The MA 21 connector unit is used to connect hand-held scanners or other devices featuring
an RS 232 interface to the Leuze multiNet plus network or to connect directly to a host
computer featuring an RS232, RS422, RS485 or TTY interface.
The MA 21 is a variation of the MA 30. For this reason the MA 21 contains operational
controls and display elements that have no function.
These operational controls and display elements are labelled accordingly in the description
that follows.

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
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 software protocol - the multiNet plus protocol. This makes wiring the network easy and inexpensive 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 software"). All standard protocols including 3964/RK512 are thus covered.

Addressing in the network
Addressing via ASCII address
Addressing the individual barcode readers or devices is necessary for the functioning of the
network so that the data read can be matched to a station. 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 via software or hardware (rotary switch).
The following rules apply:
Master (MA 30):
Addr. 00
Slaves:
Addr. 01 to Addr. 30 (sequentially numbered)
No address may occur twice in the network. The numbering must be without gaps, i.e. all
addresses up to the last slave address (=last subscriber in the network) must be occupied.
Notice!
Be careful to select the network addresses correctly during commissioning.
The logical order of the assigned addresses does not have to correspond to the physical order of the read stations in multiNet plus.

Service interface
The MA 21 offers the service interface for commissioning the connector unit. It can be
accessed once the MA 21 housing cover has been removed and features a 9-pin, Sub-D
connector (male).
Connection
You can use this to connect a PC or terminal to the MA 21 via the serial RS 232/V.24 interface in order to configure the device. The connection is made using a crossed RS 232
connection cable that establishes the RxD, TxD and GND connections. A hardware handshake via RTS, CTS is not supported at the service interface.

Exiting service mode
As soon as DIP switch 3 is switched back to "Host", the host interface is reactivated.
Data monitoring
When the service interface is in this position, it is possible to "listen" to the data via the
RS 232 as they are transferred from the MA 21 to the host computer (data monitoring).
To do this, you must set your PC / terminal to the host protocol as the host interface is only
passively decoupled with no change of protocol.

Hints for connecting the TTY interface:
• The active subscriber is the one which supplies the current (20 mA).
• Switching between active/passive on the host interface card is carried out using two
jumper pairs, independent for transmit (Tx) and for receive (Rx).
• The jumpers for active/passive switching must always be changed in pairs (upper and
lower jumpers in the same position). Thus the current source and GND are switched
internally at the MA 21 host interface module.
• Mixed operation is possible (transmit active/receive passive or vice versa).
• When switching between active and passive operation or vice versa, the pin order of
the connection cable is changed (pin assignment).

Connection
Hints for connecting the multiNet plus interface:
• The RS 485 A, 485 B and GND lines are passed through in the network; for the MA 30,
MA 21, MA 10 and MA 90 the corresponding terminals are doubly provided for this
purpose.
• Connect the shielding to the slaves with GND.
• The maximum wire length in the network is 1200 m.
• The (physically) last slave in the network should be fitted with a 220 Ω terminating resistor between 485 A and 485 B. This prevents reflections and improves resistance to
interference.
• 485 A and 485 B wires must in no case be exchanged within the network. The multiNet
will otherwise not function.

Setting parameters
To activate network operation with the MA 21, it may be necessary to set several parameters. For best results use the BCL-Config or IRF-Config software for PCs, programs developed expressly for this purpose. With the aid of these programs, you can use a fixed data
format via the service interface of the MA 21 to configure the host and client interface.
You can download the config. tool from www.leuze.de -> Download -> Identify for BCL,
RFID, VR etc.

Managing parameter sets in the MA 21
Parameter sets
The MA 21 is capable of managing three types of parameter sets
A "parameter set" refers to a memory area in the EEPROM that contains all settings (parameters) of a read station such as code type, number of digits, output formatting etc. in numerical form. The BCL-Config configuration software facilitates menu-driven parameter setting.
For the software handling of the parameter sets, these are sequentially numbered from "0"
to "2".

Current parameter set ("0"):
parameter set that can be changed via an online or offline setup and that contains the
current settings of the MA 21.

Customer-specific parameter set ("1"):

parameter set for the purpose of storing customer-specific settings. As a result, the
customer-specific data are retained following a hardware reset.
Factory parameter set ("2"):
Leuze standard parameter set that cannot be changed.
The settings correspond to the state upon delivery.
By means of a hardware RESET (see chapter 6.4.2), it is possible to restore the factory settings of the MA 21.

With the online command "Parameter Copy", abbreviated "PC", you can copy a given
parameter set as a backup, so to speak, into the customer-specific parameter set and use
a hardware RESET to return the read station to this state at any time (cf. chapter 6.4.2).
Commands for handling the parameter sets via software:
PC01:
copies the current parameter set to the customer-specific parameter set
PC10:
copies the customer-specific parameter set to the current parameter set (corresponds to hardware RESET with customer-specific parameters)
PC20:

6.4
Executing a RESET
6.4.1
Software RESET ("warm start")
Software RESET
In the event that the MA 21 no longer responds in spite of having applied the operating
voltage, and the RDY LED no longer illuminates, you should first perform a software RESET.
To do this, press the RESET button on the MA 21 for more than 0.2 and less than 4.0 s.
If the MA 21 does not respond even after carrying out a warm start, there may be an error
in the setup settings, i.e. in the "current parameter set" of the MA 21. A hardware RESET
(see chapter 6.4.2) returns the parameter set of the MA 21 to a defined state so that the
devices are operable again.
6.4.2
Hardware RESET ("cold start")
Hardware RESET
By means of a cold start, you can either reset the MA 21 to factory settings (factory parameter set) or to your customer-specific parameter set. Which parameter set is loaded depends
on the position of DIP switch 2. Initiate a cold start by pressing the RESET button for more
than 4 s.
Attention!
A cold start replaces the current parameter set either with your customer-specific parameter
set or the Leuze factory parameter set, i.e. any settings made there are lost. Therefore perform a hardware RESET only if the software cannot be started or if you intentionally want to
reset the MA 21.
