3.3.1
Connecting the Leuze device
 To connect the Leuze device to the internal RS 232 device interface, open the housing
of the MA 255i and guide the corresponding device cable (see chapter 14.7, e.g., KB 031
for BCL 32) through the middle threaded opening.
 Connect the cable to the internal device interface (X30, X31 or X32, see chapter 7.5.1).
 Use rotary switch S4 (see chapter 8.2.5) to select the connected device.
 Now screw the PG cable gland into the threaded opening to provide strain relief and
ensure protection class IP 65.
3.3.2
Setting the DeviceNet device address
 Set the station address of the gateway using the two rotary switches S1 and S2 (ones
and tens places).
Notice!
The DeviceNet permits an address range from 0 to 63. Other addresses must not be used
for data communication.

3.3.3
Setting the DeviceNet baud rate
 Set the baud rate of the gateway via the S3 rotary switch to the value defined in the control.
Notice!
The DeviceNet baud rate is defined for the entire network in the planning tool/control. The
baud rate is set on the MA 255i via the baud rate selector switch. Only if the baud rates are
the same is communication with the MA 255i possible.
Figure 3.3:
Rotary switch for setting baud rate
 Finally, close the housing of the MA 255i.
Attention!
Only then may the supply voltage be applied.
Upon startup of the MA 255i, the device selection switch and the address settings are
queried and the gateway automatically sets itself to the Leuze device.
 Ensure that the functional earth (FE) is connected correctly.
Unimpaired operation is only guaranteed when the functional earth is connected properly.
All electrical disturbances (EMC couplings) are discharged via the functional earth
connection.
3.3.4
Connecting the power supply and the bus cable
 Ideally, use the ready-made cables listed in chapter 14.5.3 to connect the gateway to the
power supply via the PWR IN connection.
 The ready-made cables listed in chapter 14.6.4 are preferred for connecting the gateway
to the fieldbus via the HOST / BUS IN connection.
 If applicable, use the BUS OUT connection if you would like to construct a network with
linear topology.

Starting the device
 Apply the supply voltage +18 … 30 V DC (+24 V DC model).
The MA 255i starts up; the PWR LED displays that it is ready for operation.
3.5
MA 255i on the DeviceNet
 Install the EDS file corresponding to the MA 255i in your planning tool/the control
(e.g., RSNetWorx DeviceNet).
Notice!
You can find the EDS file at:
www.leuze.com -> Download -> identify -> Modular interfacing units.
The MA 255i is configured in the planning tool/control by means of the EDS file. The MA 255i
is assigned an address in the planning tool, which then has to be set in the MA 255i via the
S1 and S2 address switches. Only if the addresses are the same between the MA 255i and
the control can communication be established.
After all parameters have been set in the planning tool/control, the download to the MA 255i
takes place. The set parameters are now stored on the MA 255i.
Afterwards, all MA 255i parameters should be stored via upload in the control. This aids in
retaining the parameters during device exchanges, as they a re now also stored centrally in
the control.
The DeviceNet baud rate is defined for the entire network in the planning tool/control. The
baud rate is set on the MA 255i via the S3 baud rate selector switch.
Only if the baud rates are the same is communication with the MA 255i possible.
Detailed information can be found in chapter 12.

4.1
General Information to the connector units
The modular interfacing unit of the MA 2xxi family is a versatile gateway for integrating Leuze
RS 232 devices (e.g., BCL 22 bar code readers, RFID devices, RFM 32, AMS 200) in the
respective fieldbus. The MA 2xxi gateways are intended for use in industrial environments
with a high protection class. Various device versions are available for the conventional
fieldbuses. With a stored parameter structure for the connectable RS 232 devices,
commissioning could hardly be simpler.
4.2
Characteristics of the connector units
1.
Transparent mode
In this function mode, the MA 255i functions as a pure gateway with automatic
communication from and to the PLC. Absolutely no special programming by the user
is necessary for this purpose. The data is not buffered or stored temporarily, however.
Instead, it is "passed on".
The programmer must make certain to retrieve the data from the input memory of the
PLC at the right time, as it is otherwise overwritten by new data.
2.
Collective mode
In this operating mode, data and telegram parts are temporarily stored in the memory
(buffer) of the MA and sent to the RS 232 interface or to the PLC in a telegram by means
of bit activation. In this mode, however, all communication control must be
programmed on the PLC.
This function mode is helpful, for example, for very long telegrams or when one or
more codes with long code lengths are read.
3.
Command mode
With this special operating mode, it is possible to use the first bytes of the data range
to transmit predefined commands to the connected device by means of bit activation.
For this purpose, device-dependent commands (so-called online commands) are
predefined via the device selection switch, see chapter 16 "Specifications for Leuze
end devices".

Device description
4.3
Device construction
The MA 255i modular interfacing unit is used for interconnecting Leuze devices, such as
the BCL 8, BCL 22, etc., directly to the fieldbus. This is accomplished by transmitting the
data from the Leuze device via an RS 232 (V.24) interface to the MA 255i where a module
converts it into the fieldbus format. The data format of the RS 232 interface corresponds to
the standard Leuze data format.

Connection of a Leuze devices (BCL, RFI, RFM, VR) to the fieldbus
The cable of the respective Leuze device is guided through cable bushings with PG cable
glands into the MA 255i and connected there with the PCB connectors.
The MA 255i is intended as a gateway for any RS 232 devices, e.g., BCL 90 with MA 90,
hand-held scanners, scales or for coupling a multiNet network.
The RS 232 cables are internally connectable using JST plug connectors. The cable can be
connected to the device using a stable PG cable gland which provide strain relief and
protection against contamination.
With the help of adapter cables with Sub-D 9 or open cable end, other RS 232 devices can
also be connected.

Operating modes
For fast commissioning, the MA 255i offers an additional operating mode, the "Service
mode", in addition to the "Standard mode". In this operating mode, the Leuze device can,
for example, be configured on the MA 255i and the communication can be tested on the
fieldbus. To do this, you need a PC/laptop with a suitable terminal program, as BCL-Config
from Leuze or similar.
Service switch
Select between "operation" and "service" modes with the service switch. You have the
following options:
Pos. RUN:
Operation
The Leuze device is connected to the fieldbus and communicates with the PLC.
Pos. DEV:
Service Leuze device
The connection between the Leuze device and the fieldbus is interrupted. With this
switch position, you can communicate directly with the Leuze device at the fieldbus
gateway via RS 232. You can send online commands via the service interface,
configure the Leuze device using the corresponding BCL- BPS-, …-Config
configuration software and have the read data of the Leuze device output.
Pos. MA:
TNT 35/7-24V
Service fieldbus gateway
With this switch setting, your PC/terminal is connected with the fieldbus gateway. In
doing so, the current setting values of the MA (e.g. address, RS 232 parameters) can
be called up via a command.
Figure 4.2:
Service-switch switch positions
Notice!
If the service switch is on one of the service settings, the PWR LED flashes on the front side
of the device, see chapter 8.1.2 "LED indicators on the housing".
Furthermore, on the control, the SMA service bit of the status bytes signals that the MA is
in service mode.

fieldbus systems such as PROFIBUS DP, PROFINET-IO, DeviceNet and Ethernet.
4.5.1
DeviceNet
The MA 255i is designed as a DeviceNet device with a baud rate of max. 500 k Bd. The
functionality of the device is defined via parameter sets which are clustered in objects,
classes and instances. These objects … are contained in a EDS file.
The MA 255i gateways can be operated as network devices on the DeviceNet. The MA 255i
features multiple M 12 connectors / sockets for the electrical connection of the supply
voltage, the interface and the switching inputs and outputs. Additional information on the
electrical connection can be found in chapter 7.2.
The MA 255i supports:
•
•
•
•
DeviceNet slave functionality
CIP profile
baud rates of 125 kBd, 250 kBd and 500 kBd
no slave address modification via DeviceNet

Attention!
The topologies presented here are enabled according to the directives of the ODVA.
It possible to connect the participants directly to the master line (trunk line) or to the stub
cable (drop line) via a tap.
On the respective ends of the trunk line (master line), the bus must be terminated with a 120
ohm terminating resistor. The terminating plug is optional and can be ordered separately
(see chapter 14.3 "Accessory terminating resistor").
A cable specified by the ODVA is required for connecting the participants to DeviceNet. Only
cables that satisfy the ODVA specifications may be used.
The limits of network expansion without repeater are specified by the ODVA. The specified
limit values are dependent on the design of the data line.
A distinction is made between "thick cable", "mid cable" and "thin cable".

Device description
DeviceNet installation
Up to 64 network devices can communicate with one another in a DeviceNet network with
baud rates of 125, 250 or 500 kBaud. In addition to the two signals for data transmission—
CAN-L and CAN-H—the DeviceNet cable also includes two cables for supplying the
DeviceNet network device with 11 … 25 V DC-volt. The connection of the MA separates the
operating voltage and the field bus voltage, the transmission electronics, however, require
V+ and V- via the CAN cable.
The maximum length of the DeviceNet cable is dependent on the selected cable type and
baud rate.
Listed in the table are the max. network expansions as a function of the used data line
without repeater.

Communication
The gateway MA 255i supports the CIP-based DeviceNet protocol and requires the EDS
file (Electronic Data Sheet) for communication; it is provided in the Download area of the
Leuze home page.
You can find the EDS file at:
www.leuze.com -> Download -> identify -> Modular interfacing units.
The EDS file is named "MA255i.eds"; the corresponding icon is named "MA255i.ico".
The EDS file includes all communication parameters of the participants as well as the available objects. The DeviceNet communication tool reads the EDS files of the participants
present in the network and uses this information to calculate the configuration data that is
subsequently loaded onto the participants.
The input/output data is addressed according to the following fundamental scheme:
1.
2.
3.
4.
5.
20
Device address (MAC ID)
The participant is addressed with its MAC ID, which is unique in the network.
Object class identifier (class)
Used as the basis for addressing the desired object class.
Object instance identifier (instance)
Addressing of the object instance within the object class.
Attribute identifier (attribute)
Addressing of the attribute within the object instance.
Service code (get, set, reset, start, stop and others...)
The maintenance code ultimately describes the type of access to the data, e.g.,
reading or writing.

The gateway is set via the switch position on the Leuze device. If the switch position is
changed, the device must be restarted, since the switch position is only queried after
switching off completely and then restarting the device.
Note!
In switch position "0", a distance of >20 ms must be maintained between two telegrams so
they can be distinguished from one another.
The parameters of the Leuze end devices are described in chapter 16.

Structure of the fieldbus telegram
All operations are performed by control and status bits. Two bytes of control information
and two bytes of status information are available for this purpose. The control bits are a part
of the output module and the status bits are a part of the input bytes. The data starts with
the third byte.
If the actual data length is longer than the data length configured in the gateway, only part
of the data is transmitted; the remaining data is lost. In this case, the DL (data loss) bit is set.

Modes

Modes
11.1
Functionality of the data exchange
The fieldbus gateway has two different modes that can be selected via the PLC:
• Transparent mode (default setting)
In Transparent mode, all data are sent 1:1 and directly by the serial end device to the
PLC. It is not necessary to use status and control bits here. However, only data bytes
possible for one transmission cycle are transmitted - all others are lost.
The distance between two successive telegrams (without frame) must be more than
20 ms, since there is otherwise no clear separation between them.
ASCII characters are typically expected as data content; under certain circumstances,
the MA therefore detects different control characters as invalid characters in the data
range and truncates them. At 00h in the data range, the MA cuts the telegram off
because unnecessary bytes are also filled with 00h .
• Collective mode
In Collective mode, the data of the serial end device is stored temporarily in the fieldbus
gateway by toggling the CTB bit and is not sent to the PLC in blocks until prompted
to do so by the PLC.
On the PLC, a status bit (DEX) then signals that new data is ready for retrieval. This
data is then read out from the fieldbus gateway in blocks (toggle bit).
In order to distinguish between the individual telegrams on the PLC, in Collective mode
the serial frame is sent to the PLC in addition to the data.
The size of the buffer is 1 kByte.
Notice!
In Collective mode, the CTB and SFB bits are needed for communication handling via the
buffer. Telegrams that can also be completely transmitted in one cycle in Collective mode
(including data frame) go directly through. If PLC data is provided and transferred without a
state change of the CTB bit, it goes directly to the RS 232 interface with the set telegram
data length. Incomplete (incl. data frame) or faulty telegrams can cause error messages in
the connected device!
Combination with the Command mode is possible.
Data exchange in blocks must be programmed on the PLC.

Modes
11.1.1 Reading slave data in Collective mode (gateway -> PLC)
If the Leuze device transmits data to the fieldbus gateway, the data is stored temporarily in
a buffer. The PLC is signaled via the "DEX" bit that data is ready for retrieval in the memory.
Data is not automatically transmitted.
If no further user data is present in the MA 255i ("DEX" bit = "0"), the "R-ACK" bit must be
toggled once as read confirmation to release data transmission for the next read cycle.
If the buffer still contains more data ("DEX bit = 1), the next remaining user data present in
the buffer is transmitted by toggling the "R-ACK" control bit. This process is to be repeated
until the "DEX" bit returns to "0"; all data has then been removed from the buffer. "R-ACK"
must be toggled here again once more as a terminating read confirmation in order to release
data transmission for the next read cycle.

11.1.2 Writing slave data in Collective mode (PLC -> gateway)
Writing in blocks
The data sent by the master to the slave is first collected in a "transmit buffer" by setting
the "CTB" bit (Copy to transmit buffer). Please observe that data provided is transmitted
directly by toggling the bit.
Afterward, the buffer is again empty and can be written with new data.
Notice!
With this function, it is possible to temporarily store longer data strings in the gateway
independent of how many bytes the used fieldbus can transmit at once. With this function,
longer PT sequences or RFID write sequences, for example, can be transmitted, since the
connected devices can, in this way, receive their commands (e.g., PT or W) in a continuous
string. The respective frame (STX CR LF) is needed to differentiate between the individual
telegrams.
Used status and control bits:
• CTB
• SFB
W-ACK
Leuze electronic
MA 255i
53
TNT 35/7-24V
The data is then sent in the order received from the buffer to the connected Leuze device
via the serial interface with the command: "SFB" (Send data from transmit buffer). Please
don't forget the suitable data frame!
Modes
If PLC data is provided and transferred without a state change of the CTB bit, it goes directly
to the RS 232 interface with the set telegram data length. Incomplete (incl. data frame) or
faulty telegrams can cause error messages in the connected device!
Examples for the activation of a Leuze device
In the data part (starting at byte 2) of the telegram to the gateway, a "+" (ASCII) is sent for
activation.
This means that the hex value "2B" (corresponds to a "+") is to be entered in control or output
byte 2. To deactivate the reading gate, a "2D" (hex) must be used instead (corresponds to
a "-" ASCII).

Command mode
One specific feature is the so-called Command mode, which is defined via the output control
byte 0 (bit 0)... and enables the control of the connected device per bit.
If the Command mode is activated (Command mode = 1), no data is sent by the PLC to the
Leuze end device via the gateway. The data from the MA to the PLC is transmitted in the
selected operating mode (Transparent/Collective).
With the Command mode, it is possible to set various device-specific bits in the data- or
parameter field that execute the corresponding serial commands (e.g., v, +, -, etc.). If, for
example, the version of the Leuze end device is to be queried, the corresponding bit is to
be set so that a "v" is sent to the Leuze device with the <STX> v <CR> <LF> frame.
The Leuze end device also answers the gateway with data (e.g. bar code content, NoRead,
device version, etc.) in response to most commands. The answer is immediately passed on
to the PLC by the gateway.
Notice!
The parameters available for the individual Leuze devices are listed in chapter 16.
Command mode cannot be used with hand-held scanners.

Commissioning and configuration
12.1
Measures to be performed prior to the initial commissioning
 Before commissioning, familiarize yourself with the operation and configuration of the
MA 255i.
 Before connecting the supply voltage, recheck all connections and ensure that they
have been properly made.
The Leuze device must be connected to the internal RS 232 device interface.
Connecting the Leuze device
 Open the housing of the MA 255i and guide the corresponding device cable (e.g., KB 031
for BCL 32) through the middle threaded opening.
 Connect the cable to the internal device interface (X30, X31 or X32, see chapter 7.5.1).
 Use rotary switch S4 (see chapter 8.2.5) to select the connected device.
 Now screw the PG cable gland into the threaded opening to provide strain relief and
ensure protection class IP 65.
Set DeviceNet device address
By setting the DeviceNet address, the MA 255i is assigned its respective station number.
Each network device is thereby automatically informed that it is a slave on the DeviceNet
with its specific address and that it is initialized and queried by the PLC.
 Set the station address of the gateway using the two rotary switches S1 and S2 (ones
and tens places).
Tens
Ones
Figure 12.1: Rotary switch for setting the address
Leuze electronic
MA 255i
59
TNT 35/7-24V
The DeviceNet permits an address range from 0 to 63. Other addresses must not be used
for data communication.
Commissioning and configuration
Set DeviceNet baud rate on the MA
The DeviceNet baud rate is defined for the entire network in the planning tool/control. The
baud rate is set on the MA 255i via the baud rate selector switch. Only if the baud rates are
the same is communication with the MA 255i possible.
 Set the baud rate of the gateway via the S3 rotary switch to the value defined in the control.
Figure 12.2: Rotary switch for setting baud rate
 Finally, close the housing of the MA 255i.
Attention!
Only then may the supply voltage be applied.
Upon startup of the MA 255i, the device selection switch and the address settings are
queried and the gateway automatically sets itself to the Leuze device.

 Check the applied voltage. It must be in the range between +18V … 30 V DC.
Connecting functional earth FE
 Ensure that the functional earth (FE) is connected correctly.
Unimpaired operation is only guaranteed when the functional earth is connected properly.
All electrical disturbances (EMC couplings) are discharged via the functional earth connection.
On delivery, the SWIO 1/2 are connected in parallel on PWR IN/OUT. This connection can
be separated with a jumper.

Starting the device
 Apply the supply voltage +18 … 30 V DC (+24 V DC model); the MA 255i starts up.
12.3
Configuration steps for a Rockwell control
The following steps are necessary for commissioning with a Rockwell control:
• Creating the hardware configuration in the DeviceNet planning tool/the control
(e.g. RSNetWorx)
• Installation of the EDS file
• Setting the parameters on the MA
12.3.1 Setting the hardware configuration
Enter the MA 255i in your project in the configuration of the DeviceNet system. Proceed as
follows:
 First, load the EDS file for the device via EDS wizard into the PLC database.
 After loading, select the device via the device list and enter it into the HW manager via
Drag&Drop.
 Open the input dialog for setting the address and additional parameters by doubleclicking on the device symbol and make the desired entries here.
TNT 35/7-24V
 Finally, transmit the values to the device via download.

Commissioning and configuration
12.3.2 Installation of the EDS file
The MA 255i is configured in the planning tool/control by means of the EDS file.
 Install the EDS file corresponding to the MA 255i in your planning tool/the control
(e.g., RSNetWorx).
Notice!
You can find the EDS file at:
www.leuze.com -> Download -> identify-> Modular interfacing units.
If the MA 255i has been assigned an address in the planning tool, the address is to be set
on the MA 255i via the S1 and S2 address switches, see chapter 12.1 "Measures to be
performed prior to the initial commissioning", section "Set DeviceNet device address" on
page 59. Only if the addresses are the same between the MA 255i and the control can
communication be established.
12.3.3 Setting the parameters on the MA
Notice!
There are two options for changing the parameters of the MA: setting is either performed
on the DeviceNet master via the scan list (communication parameters), or setting is enabled
by temporarily removing the participants from the scan list. After successful parameter
change, the participant can be re-added to the scan list.
TNT 35/7-24V
This is illustrated in the following screenshot from the RSNetWorx for DeviceNet
configuration tool:
Leuze electronic
MA 255i
63
Commissioning and configuration
Variable configuration of the communication data width
The communication of the MA 2xxi with the fieldbus system can be configured with a
variable data width; the upper limit is restricted by the fieldbus. For DeviceNet, a value
between 4 and 240 bytes (120 bytes each for input and output data) can be set.
The small data lengths (< 28 bytes) are particularly of interest for use with bar code scanners
(BCL). The larger data lengths are, on the other hand, relevant for 2D code scanners (handheld scanners, LSIS) and RFID.
Notice!
The representation of the (Rockwell) control is usually set to double word (DINT, 4 bytes).
Please observe that in this representation, the byte sequence can vary in contrast to the read
code.
After all parameters have been set in the planning tool/control, the download to the MA 255i
takes place. The set parameters are now stored on the MA 255i.
Afterwards, all MA 255i parameters should be stored via upload in the control. This aids in
retaining the parameters during device exchanges, as they a re now also stored centrally in
the control.
Each time a connection is established between the control and the MA 255i, these
parameters are now transmitted again to the MA 255i. Note that this function must be
supported by the control.
The DeviceNet baud rate is defined for the entire network in the planning tool/control. The
baud rate is set on the MA 255i via the S3 baud rate selector switch.
Only if the baud rates are the same is communication with the MA 255i possible.
12.4
EDS file - general info
The EDS file contains all identification and communication parameters of the device, as well
as the available objects.
The MA 255i is uniquely classified via a class 1 identity object (component of the
MA255i.eds file) for the DeviceNet master.
The identity object contains, among other things, a manufacturer-specific vendor ID, as well
as an ID that describes the principle function of the participant.
The MA 255i has the following identity object (class 1):
Vendor ID: 524 dec./ 20CH
Device type: 12 dec / 0CH (labels the MA 255i as "communications adapter")
Position sensor type: product type 1004 (specifies the MA 255i as "gateway")
64
MA 255i
Leuze electronic
Commissioning and configuration
The types of communication access to the data of the MA 255i described by the ODVA:
• Polling
• Cyclic
• Combinations of polling and cyclic
are supported by the MA 255i.
Communication access via change of state is not implemented and must not be activated
in the network configuration.
If accepting the objects without change, all parameters are set to default values. The default
settings are shown in the objects described in detail in the "Default" column.
Attention!
The Rockwell control offers the possibility of activating the Configuration Recovery
function. This stores the parameters defined in the EDS file in the control. If necessary, an
automatic parameter download from the control to the MA 255i takes place.
Leuze electronic recommends activating "Configuration Recovery". This stores all
parameters in the control.
Notice!

Setting the read parameters on the Leuze device
Commissioning the Leuze device
To commission a read station, you must prepare the Leuze device on the MA 255i for its
reading task. Communication with the Leuze device occurs via the service interface.
Notice!
For further information on connecting and using the service interface,
see chapter 9 "Configuration".
 To do this, connect the Leuze device to the MA 255i.
Depending on the Leuze device, this occurs either via a connection cable
(accessory no.: KB 031-1000) or directly on the MA 255i. The service connector
and corresponding switches can be accessed with the housing cover open.
 Select the "DEV" service switch position.
Connect the service interface; call up the terminal program
 Connect your PC to the service connector via the RS 232 cable.
 On the PC, call up a terminal program (e.g., BCL-Config) and check whether the interface
(COM 1 or COM 2) to which you have connected the MA 255i is set to the following Leuze
standard setting: 9600 baud, 8 data bits, no parity, 1 stop bit and STX, data, CR, LF.
You can download the config. tool from www.leuze.com -> Download -> identify for BCL,
RFID, VR etc.
In order to communicate with the connected Leuze device, the STX, data, CR, LF framing
must be set on the PC terminal program, as the Leuze device is preconfigured ex works for
this frame character.
STX (02h):
Prefix 1
CR (0Dh):
Postfix 1
LF (0Ah):
Postfix 2
Operation
 Switch the MA 255i to switch position "RUN" (operation).
The Leuze device is now connected to the fieldbus. Activation of the Leuze device can now
occur via the switching input on the MA 255i, via the process data word Out-bit 1 (Bit 0.2)
or by transmitting a "+" command to the Leuze device (see chapter 16 "Specifications for
Leuze end devices"). For further information on the fieldbus transmission protocol, see see
chapter 10 "Telegram".

Commissioning and configuration
Reading out information in service mode
 Set the service switch of the gateway to switch position "MA" (gateway).
 Send a "v" command to call up all service information of the MA 255i.
An overview of the available commands and information can be found in chapter "Reading
out information in service mode" on page 41.
12.6.1 Specific feature for the use of hand-held scanners
(bar code and 2D devices, combi devices with RFID)
Notice!
For a description of device configuration and the required codes, please see the
corresponding documentation at www.leuze.com -> Download -> identify -> Bar code
hand-held readers or 2D code hand-held readers.
12.6.1.1 Cable-connected hand-held scanners on the MA 255i
All hand-held scanners and mobile combi devices available in the Leuze electronic product
line can be used with the corresponding connection cable.
When using the MA 255i, the voltage supply of the hand-held scanner (5 V/at 1 A) can be
connected to the interface by means of a cable via the 9-pin Sub-D connector (voltage on
PIN 9). The corresponding cable is to be selected for the respective hand-held scanner and
ordered separately. The 9-pin Sub-D cable (KB JST-HS-300, Part no. 50113397) is
connected to this cable, which is connected to the MA 255i. This cable must also be ordered
separately.
In this example, triggering occurs by means of a trigger button on the hand-held scanner.
All cableless hand-held scanners and mobile combi devices available in the Leuze electronic
product line can be used with the corresponding connection cable via the base station.
A 230 VAC connection (socket) is usually necessary for the charging station. Here, a data
connection of the charging station is established with the MA 255i. The corresponding cable
is to be selected for the respective hand-held scanner and ordered separately. The 9-pin
Sub-D cable (KB JST-HS-300, Part No. 50113397) is connected to this cable, which is
connected to the MA 255i. This cable must also be ordered separately.
In this example, triggering occurs by means of a trigger button on the hand-held scanner.
The following codes for configuring the devices are necessary for these devices as well.

Specific features in the operation of an RFM/RFI
When using the MA 255i in connection with an RFID device, we recommend a data width
of at least 24 bytes to be able to transmit information to or from the reader in a telegram.
Shown here is a sample telegram for a write command in combination with an RFID device.
Notice!
Also note that all characters which are sent to a transponder are hex-encoded ASCII
characters. Each of these (hexadecimal) characters is, in turn, to be handled as an individual
ASCII character and converted to hexadecimal format for transmission via the fieldbus.

Serial interface and Command mode
The corresponding Leuze end device can be selected while configuring the fieldbus gateway
(see chapter 9 "Configuration").
The exact specifications for the individual Leuze end devices can be found in the following
sections and in the device description.
The corresponding serial command is sent to the Leuze end device in Command mode. To
send the corresponding command to the RS 232 device after activating the Command
mode in byte 0 (control bit 0.0), set the corresponding bit in byte 2.
The Leuze end device also responds to most commands by sending data, such as the bar
code contents, NoRead, device version, etc., back to the gateway. The answer is not evaluated by the gateway, but is instead passed on to the PLC.
For the BPS 8, AMS and hand-held scanners, a number of specific features are to be noted.
16.1
Standard setting, KONTURflex (S4 switch position 0)
This switch position can be used with almost all devices, since a data frame is transmitted
along with it if necessary. A 00h in the data range of the control is interpreted as the end of
a telegram/invalid, however.
The distance between two successive telegrams (without frame) must be more than 20 ms
in this switch position, since there is otherwise no clear separation between them. If necessary, the settings have to be adjusted on the device.
Leuze measuring sensors with RS 232 interface (such as a KONTURflex Quattro RS) do not
necessarily use a telegram frame, which is why these are also operated in switch position 0.
