Note

The N-410 allows you to add the following functions to any BL/SR/RF Series device.

N-410 Overview

 Multi-drop Link mode

The N-410 allows you to control up to 31 BL/SR/RF Series devices for each host computer. This is
called "multi-drop link".
Communications are over RS-485, making longer distances (up to 1.2 km) possible with high
noise resistance. The connection is through a twist-pair cable (two lines), meaning that minimal
wire is used.
To allow the N-410 to control communication with each BL/SR/RF Series device, the host
computer should be set up to communicate only with the N-410. This uses a very simple program
(The BL/SR/RF Series device that sent each packet of data is identified by an ID number
appended to the head of the packet). The system can thus be constructed so that load on the
host computer is extremely low.

 Multi-head mode

If the location of the code or IC tag on a product is unknown or there are multiple codes or IC
tags on a product, more than one unit will be needed to read the information. In these cases,
multiple devices will be needed to scan for barcodes or IC chips in multiple locations or from
multiple angles.
The N-410 can be used in multi-head mode in these cases to allow the host computer to control
multiple BL/SR/RF Series device as one unit.
The number of units that can be connected and the distance over which they can be connected
are the same as for multi-drop link mode, up to 31 units over 1.2 km.

The N-410 forwards the data read with a
code reader directly to the
PLC memory, so no communication
program is required.

Note



Interference suppression function
(when using a network in multi-drop mode with only BL/SR Series devices)

If the code readers must be positioned very close to each other, such as when reading a
multistage label, as shown below, their light sources may interfere with one another and have a
negative effect on the reading.
The interference suppression function activates the code reader lasers (LEDs) one after another,
thus preventing interference and stabilizing the reading.
Because the lasers are activated in an ordered fashion, the amount of time each laser (LED)
spends deactivated increases as the number of lasers connected increases. If the line speed is
too fast, the laser array may nor be able to make readings.

• An NX-50RS Series device cannot be connected to an SR-600 Series device.

 PLC link function (when using a network with only BL/SR Series devices)

The PLC link function allows data from a code reader in multi-drop link mode or multi-head mode to be
forwarded directly to a PLC without a program.
This helps reduce the number of man hours devoted to PLC programming.

• This cannot be connected to RF Series devices.

• An NX-50RS Series device cannot be connected to an SR-600 Series device.

2-1 Making Settings and Connections

Use the following steps for installation.

<Required items>

• RS-485 master unit N-410

Installation

• BL Series barcode reader, SR Series 2D code reader, RF Series RFID system

The following units are compatible with the N-410.
BL Series- BL700/600/500/180/210 Series
SR Series- SR-500, SR-510
RF Series- RF-500, RF-550

• RS-485 power source for multi-drop (N-48, BL-U1, NX-50RS)

Each BL/SR/RF Series device requires its own communication unit.

• RS-232C type communication unit (BL-U2)

When using an N-48 to power a multi-drop network, a separate communication unit will be
required to change settings on any of the BL/SR/RF Series devices because the N-48 does
not include an RS-232C.
This is not required when using a BL-U1 or an NX-50RS to power a multi-drop network.

• RS-232C cable for N-410

This cable connects the N-410 to the host computer.
Be sure to use a cable with the proper pin settings for the computer or PLC that you are using.

• RS-232C cable for BL/SR/RF Series settings

This is the cable used to connect the computer, BL-U1, BL-U2 or NX-50RS to the computer
when changing settings on a BL/SR/RF Series device. This cable is different than the RS-232C
cable for the N-410 and must be prepared separately.
Refer to the user’s manual for each device for more information about wiring.

• Twist pair cable for RS-485

Use this for the settings cable.

"Wiring an RS-485" (Page 2-24)
"Wiring an RS-485" (Page 2-30)

•Host computer

Use a computer with an RS-232C.
It is possible to exceed the data handling capacity of the host computer when large amounts
of data are being sent from multiple BL/SR/RF Series devices.
In such cases, reduce the number of BL/SR/RF Series devices connected or use a host
computer with a higher data handling capacity.

<Making Settings and Connections>

1. Set BL Series , SR Series, and RL Series devices

Use the BL/BL 210 Series AutoID Navigator software to change the settings on BL/SR/RF
Series devices. This requires preparing the BL/SR/RF Series devices, the communication unit
for an RS-232C (N-R2, BL-U1, BL-U2 or NX-50S), an RS-232C cable for changing BL/SR/RF
settings and a computer.
Refer to the user’s manual for each device for more information making settings and
connections.
The necessary settings vary greatly depending on the mode being used. Refer to the following
pages.

• Multi-drop Link mode "Settings" (Page 4-3)

• Multi-head mode "Settings" (Page 5-3)

2. Set the N-410

Use AutoID Navigator and the N-410, RS-232C cable for the N-410 and the computer to make
the settings. For more information on using AutoID Navigator, refer to the "AutoID
Navigator User's Manual".
The necessary settings vary depending on the mode being used. Refer to the following pages.

• Multi-drop Link mode "N-410 Settings" (Page 4-4)

• Multi-head mode "N-410 Settings" (Page 5-4)

• PLC link "7-1 PLC Link" (Page 7-2)

Installation

3. Set the host computer and PLC control

Change the settings for baud rate, data bits and stop bit length to match the RS-232C side of
the N-410 settings.
When using a PLC link, refer to "7-3 Settings" (Page 7-13) , then make the settings.

4. Connect BL/SR/RF Series devices to the N-410

First, connect a the BL/SR/RF Series device to a dedicated communication unit (N-R4, N-48,
BL-U1 or NX-50RS).
Then connect the communication unit to the N-410 with the specified cable, (RS-485, twist
pair). Set the terminator settings on both devices to on.
When using a BL-U1, be sure to set the dipswitch to "RS-485".

5. Connect the N-410 to the host computer or the PLC

Be sure that the RS-232C cable you are using has a pin layout compatible with your PLC or
host computer.

6. Confirm that the N-410 and BL/SR/RF Series devices are correctly connected by RS-485

The connection test mode will confirm if the N-410 and RS-485 are connected correctly and if
the AutoID Navigator is set correctly. Use it to confirm that the RS-485 connection is set up
correctly. Refer to "2-7 How to Use the Connection Confirmation Test" (Page 2-31) for more
information.

7. Connect the trigger sensor

Connect one trigger sensor for each power source.
(This is not necessary if reading operation is controlled by reading start and stop commands)
When used in multi-head mode, one trigger device is required for the N-410.
(This is not necessary if reading operation is controlled by reading start and stop commands)
Multi-head mode will not operate properly if a trigger sensor is connected to anything other than the
N-410.

connected.

AutoID Navigator are connected as set.

When using the connection test mode, the settings for the BL/SR/RF Series devices and
the N-410 must be set for a multi-drop connection.

 How to use the connection confirmation test mode

1. Once all of the devices have been turned on, press and hold the test switch on the N-410 for two
seconds to enter the connection test mode. Press and hold it for five seconds to enter connection
device confirmation test mode. The N-410 display shows the ID number of any device undergoing
a connection test. If the device is connected properly, the ID number will automatically increment
by one.

2. If there is an ID number that is not connected or that has a connection error, that number will flash
on the display.
To move to the next device, press the test switch once.

(Example) Ten BL/SR/RF Series devices with ID numbers ranging from 1 to 10.

The display will automatically increment from 1 to 10. The test can be stopped
when the number 11 begins to flash.

(Example) Fourteen BL/SR/RF Series devices with ID numbers ranging from 3 to 16.

The display will flash the number 1. Press the test switch once. The display will
then flash the number 2. Press the test switch again. The display will
automatically increment from 3 to 16. The test can be stopped when the
number 17 begins to flash.

3. If there is a BL/SR/RF Series device that should be connected but has an ID number that flashes
during the test, that device is not properly connected. After confirming the following points, run the
connection test again.

• Are the communication settings (baud rate, data bits, parity and stop bit length) for the N-410 RS­485 side and the BL/SR/RF Series devices compatible?

• Are theBL/SR/RF Series devices set to multi-drop mode?

• Is the NX-50RS set to network communication mode?

• Are all of the wires properly connected? Are the connections branched or connected to terminals?

"Wiring an RS-485" (Page 2-24)
"Wiring an RS-485" (Page 2-30)

• Do the terminating devices have their terminator switches set to on? Do the non-terminating
devices have their terminator switches set to off?

• Are the BL/SR/RF Series ID numbers set correctly? Are there conflicting ID numbers?

4. Press and hold the test switch for another 2 seconds to close the connection test mode.

Controlling Multi-drop Link Mode

Multi-drop link mode allows one host computer to control up to 31 BL/SR/RF Series devices.
To allow the N-410 to control communication with each BL/SR/RF Series device, the host
computer should be set up to communicate only with the N-410. This uses a very simple
program (The BL/SR/RF Series device that sent each packet of data is identified by an ID
number appended to the head of the packet). The system can thus be constructed so that load
on the host computer is extremely low.

Controlling Multi-drop Link Mode

The N410 can be used to control the host computer in three different ways.

• Data communication . . . . . . . . . . . . . . . . . . . . . . . . . . Sends read data to the host computer.

• BL/SR/RF Series command communication . . . . . . . Allows commands to be sent to BL/SR/RF

• N-410 command communication . . . . . . . . . . . . . . . . Controls the N-410 directly and allows N-410

settings to be changed.

Caution

The following pages explain these settings.

When using the multi-drop link mode, the maximum number of characters
(number of data digits) that can be handled in a single communication is 992
(including additional data). Be careful with the number of data digits when
sending or receiving large size data such as an IC tag or 2D code.

Multi-drop link mode allows code or tag information to be sent to the host computer via either
"auto-polling" or "manual polling".
The options are each explained below.
This is generally set to "auto-polling".

Multi-drop Link Mode Data Communication

Auto-polling

About auto-polling

Auto-polling allows the BL/SR/RF Series devices connected to an N-410 and assigned an ID
number to be continuously polled by the N-410 (using those ID numbers) at startup. The N-410
then continuously sends read data to the host computer.
The load on the host computer program is extremely low because the N-410 handles all of the
data queries automatically.

Communication format

The BL series
device with ID
number 3 read the
barcode "ABC123."

When using auto-polling, data is sent to the host computer from the N-410 in the following format.

"Auto-polling control" (Page 4-18)
Using serial commands allows you complete control over auto-polling, starting and stopping it at
any time.

Controlling Multi-drop Link Mode

Manual Polling

(About manual polling)

Manual polling is where the host computer sends a "polling command" to a BL/SR/RF Series
device and receives data from that device.
Unlike "auto-polling", "manual polling" requires that data requests (polling) be sent from the host
computer. This increases the load on the program, but can be used to prevent data from being
sent to the host computer when the host computer cannot receive data (Data is constantly sent
to the host computer regardless of the status of that computer when using "auto-polling").

"Manual polling" is available when "auto-polling" is not activated (when no ID numbers have been
registered in AutoID Navigator).

This requires that the device be registered as a slave.

(Communication procedure and communication format)

Data is sent in the following steps and in the following formats in manual polling.

Controlling Multi-drop Link Mode

(About settings)

Manual polling can be used if no ID number has been registered with the AutoID Navigator (once
ID numbers have been recorded, be sure to activate auto-polling mode).

Reference

"Auto-polling" does not send "manual polling" commands from the host computer, but rather
has the N-410 send the data received from BL/SR/RF Series devices to the host computer
as needed, thus reducing the load on the host computer.

Send Buffer Capacity

(N-410 send buffer)

The N-410 send buffer can hold up to 3000 items (up to 100 KB). If the buffer capacity is
exceeded, a buffer overflow error such as the one below will be sent to the host computer and all
send buffers will be cleared. (Error number "96" will display on the N-410)

When using SR Series or RF Series devices, the buffer will not be large enough to hold
3000 transmissions if the data size (including added data and attribute data) exceed 100
KB.

Send buffers for BL Series, SR Series, and RF Series devices

The BL-1300 Series device has a 8192 byte buffer. BL-700/600/500/180 Series devices have a
400 byte buffer. The BL-210 Series has a one item buffer. The RF Series has a 10 KB buffer.
These buffers hold data while waiting for a query (polling) from the N-410. (The N-410 polls BL/
SR/RF Series devices for the data stored in their buffers.)
If the buffer capacity is exceeded, an error such as the one below will be sent from the BL/SR/RF
Series device to the host computer and all send buffers will be cleared.
BL/SR/RF Series devices that do not have buffer overflows will operate normally.

Controlling Multi-drop Link Mode

*mm = 01 to 31: The BL/SR/RF Series device ID number

A buffer overflow indicates that the polling speed cannot keep up with the BL/SR/RF Series
device between data transmissions. This must be handled in a manner such as the following.

• Set the baud rate between the BL/SR/RF Series devices and the N-410 to maximum to reduce
the polling interval.

• Reduce the number of BL/SR/RF Series devices connected to reduce the polling interval.

• Lengthen the BL/SR/RF Series read interval to reduce the amount of data handled by the N-410.

• When using manual polling, BL/SR/RF Series devices should be altered to send a polling command
before a buffer overflow occurs.

• Delete all unconnected ID numbers in the "ID settings" of the N-410.

5-1 Multi-head Mode

Controlling Multi-head Mode

If you do not know where on a product the code is located, if there barcodes in multiple locations
or if the tag location on palletized shipping is variable, the code or tags cannot be read by a single
code reader or RF-ID. In these cases, multiple code readers will be needed to scan for barcodes
or IC chips in multiple locations or from multiple angles.
The N-410 can be used in multi-head mode in these cases to allow the host computer to control
multiple BL/SR/RF Series devices as one unit.

The N-410 can be controlled by the host computer in the following three ways.

• Data communication
Code data and tag access results are sent to the host computer.

• BL/SR/RF Series device command communication
Commands can be sent to BL/SR/RF Series devices.

• N-410 command communication
Allows direct control of the N-410 and allows N-410 settings to be changed.

Sending commands to the N-410 and to BL/SR/RF Series devices is the same as in multi-drop
link mode. Refer to "4-1 Multi-drop Link Mode" (Page 4-2) for more information.

Caution

• BL Series, SR Series, and RF Series devices cannot be mixed in multi-head
mode. Make sure that your networks are either exclusively BL/SR-Series
devices or exclusively RF Series devices when using multi-head mode.

• When using the multi-drop link mode, the maximum number of characters
(number of data digits) that can be handled in a single communication is
992 (including additional data). Be careful with the number of data digits
when sending or receiving large size data such as an IC tag or 2D code.

5-2 Operating in Multi-head Mode

Multi-head mode allows multiple BL/SR/RF Series devices to be controlled as one device.
The N-410 settings must match those of the BL/SR/RF Series devices that it is connected to.

Trigger Notification Method

Select the trigger input method from the N-410 to the connected BL/SR/RF Series devices.
Set the settings to match the configuration of the network connected to the N-410.

1.Normal (sequential) notification
Use this setting if the network configuration has the BL/SR/RF Series devices connected to the
N-410 through an N-R4, N-48 and BL-U1.

2.Broadcast notification
Use this setting if the network configuration has the BL/SR/RF Series devices connected to the
N-410 through an NX-50RS. This is useful if there are many BL/SR/RF Series devices on the
network, or if the RF Series devices are handling a large amount of data.

Controlling Multi-head Mode

Caution

3.Interference suppression (Only available for multi-head mode on a BL (SR) Series network)

Multi-head mode normally activates all of the BL Series or SR Series device light sources at the
same time.
When this happens, if the distance between code readers is small, the laser (LED) of one code
reader can be sensed by the photoreceptor of a nearby device, causing interference. This can
result in inability to read or instability (Interference will definitely result if the laser (LED) from
device overlaps the laser from another device).
As shown on the next page, interference suppression prevents the connected code readers from
illuminating at the same time, instead illuminating the lasers (LEDs) in order of ascending ID number. This
prevents interference between the lasers and allows much greater reading stability.
Operational differences that depend on the read mode and the measurement format are the
same as for normal multi-head mode.

Use normal (sequential) notification if you have both N-R4/N-48/BL-U1 and
NX-50RS communication units on the network.

5-2 Operating in Multi-head Mode

• The time of illumination for each BL/SR Series device laser (A) can be changed in the

settings. Lengthening A increases read stability, but this cannot be done with a high line
speed. Alternatively, reducing A allows for higher line speeds, however this may reduce read
stability.

Interference suppression increases the amount of time that a code reader laser is inactive,
using this function on a high-speed line drastically reduces that amount of time available for
scanning, thus increasing the risk of being unable to read.

Read Mode

 Single mode

• Single mode sends the first data read by the BL/SR/RF Series device array to the host computer.

(Once one BL/SR/RF Series device on the network has read in data, the others will cease
operation.) This allows multiple BL/SR/RF Series devices to be controlled as one device.

• When trigger input is ON, an error will result only if none of the connected BL/SR/RF Series devices

are able to read data.

• Data will normally be sent as soon as it has been read, but it is possible to have the data sent after

the trigger input has been turned OFF.

Controlling Multi-head Mode

 Multi mode

• In multi mode, all data obtained by the connected BL/SR/RFSeries devices while the trigger input is

on is sent.

• BL/SR/RF Series devices that encounter an error do not send any data.

• When trigger input is on, a single error code will be sent only if none of the connected BL/SR/RF

Series devices are able to read data.

• Data will normally be sent as soon as it has been read, but it is possible to have the data sent after

the trigger input has been turned OFF.

6-1 Serial Communication Outline

Serial communication can be used to send data from an N-410 Series device to a host computer,
as well as to send operating directions from the host to BL, SR, and RF Series devices via the N­410 Series device. In addition, it is also possible to change the settings of the N-410 Series
without using the AutoID Navigator setting software.

Type of Serial Communication

Two types of communication are available between the N-410 Series device and a host
computer.
Both types use ASCII code for communication data.

 Data communication

It refers to the communication that the N-410 Series device sends data to a host computer.

 Command communication

It refers to communication of operational and setting commands sent from a host computer to BL,
SR, and RF Series devices that are connected to the N-410 Series.

Serial Communication Setup

Users must set the communication parameters for the N-410 Series device and the host
computer before starting serial communication.
Communication parameters for the N-410 Series device can be specified by using the AutoID
Navigator setting software.

 Setting the RS-232C of the N-410 Series device

• Baud rate : 9600, 19200, 38400, 57600, or 115200 bit/s

• Data length : 7/8 bits

• Parity : None/even/uneven

• Stop bit length : 1/2 bit

 Factory-default communication settings of the N-410 Series device

The setting of the RS-232C is as follows when the N-410 Series device is shipped.

Baud rate 115200 bit/s
Data length 8 bits
Parity Even
Stop bit length 1 bit

Read data

Response (PASS,RTRY)

This section describes the communication protocols and formats used for data communication.

Communication Protocol

The N-410 Series supports the following four handshaking protocols (data transfer procedures).
Both multi-drop Link Mode Data Communication (Auto-polling/manual polling), multi-head mode
data communication operate in the same way.

 No handshake

• The read data is sent to the host computer constantly. In other words, transmission is unregulated.

 PASS/RTRY protocol

Serial Communication

• After read data is sent, the N-410 waits for a response (PASS or RTRY) from the host computer.

If a PASS (normal function) signal is sent to the N-410, one transmission has been completed and
the next can begin.
The N-410 does not send a response to a PASS signal.

• If the N-410 receives a RTRY (resend request) while waiting for a PASS signal, it resends the data and

resumes waiting for a PASS signal.
The N-410 does not reply to a RTRY signal if it has already received a PASS signal.

• Reading can occur while the device is waiting for a PASS signal. If this happens, the read data will

be stored in the N-410 send buffer.
If the send buffer capacity is exceeded, the N-410 will send an OVER message to the host computer all
data in the send buffer will be cleared.
In this case, the N-410 will halt and will reactivate upon receiving an OVCLR signal or having the
TEST switch pressed.
Refer to "Send Buffer Capacity" (Page 4-9) for more information on send buffer capacity and
the OVER signal.

• The PASS and RTRY formats

are all possible. At the head of the command, or at the end may be added.

• All commands can be received while waiting for a PASS signal. In this case, a response
(such as OK) to a command can be sent without delay.

• If an SSET command is sent to the N-410 while it is waiting for a PASS signal, the send buffer
will be cleared and setting mode will be initiated.

"Changing to setting mode" (Page 4-20)

Serial Communication

 ACK/NAK protocol

This is similar to the PASS/RTRY protocol explained above except that, instead of PASS
(06H) is sent and instead of RTRY, (15h) is sent. Besides the differences in the
character strings used, all operations are identical.

 RTS/CTS protocol

• Turning off the RS-232C RTS signal allows the device to wait to send data. When RTS is turned on,
the data is sent.

• Reading can still occur while RTS is turned off. If this happens, the read data will be stored in the
N-410 send buffer.
Data in the send buffer will be cleared if there is a buffer overflow. In this case, the N-410 will halt,
RTS will be turned on and the N-410 will send an OVER signal to the host computer. The N-410 will
reactivate upon receiving an OVCLR signal or having the TEST switch pressed.
Refer to "Send Buffer Capacity" (Page 4-9) for more information on send buffer capacity and
the OVER signal.

RTS/CTS can be used with other protocols.
