4-1 Multi-drop Link 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).
4-1 Multi-drop Link Mode Settings Refer to "2-1 Making Settings and Connections" (Page 2-2) for the procedure for making settings and connections. The section explains how to make the settings for the N-410, BL/SR/RF Series devices and the computer. 4 Settings for BL/SR/RF Series devices When using an N-R4/N-48/BL-U1 Controlling Multi-drop Link Mode 1. Set multi-drop link to "Enabled". 2. Set the ID number of the BL/SR/RF Series device to be connected to a number from 1 to 31.
4-1 Multi-drop Link Mode N-410 Settings Make the following settings in the AutoID Navigator. 1. Set multi-drop link to "Enabled" under "Main setting". 2. Register the connection types and ID numbers of the devices to be connected under "Slave settings". Do not record these items if using manual polling. 3. Set the communication protocol under "Protocol setting". 4. Change the settings for baud rate, data bits and stop bit length to match those of the host computer under "RS-232C settings".
4-2 Multi-drop Link Mode Data Communication 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". Auto-polling 4 About auto-polling Controlling Multi-drop Link Mode 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.
4-2 Multi-drop Link Mode Data Communication (About settings) The settings for auto-polling can be made with the AutoID Navigator or with serial commands. "Slave settings" (Page 3-6) "Auto-polling control" (Page 4-18) Using serial commands allows you complete control over auto-polling, starting and stopping it at any time.

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.
5-1 Multi-head Mode Settings Refer to "2-1 Making Settings and Connections" (Page 2-2) for the procedure for making settings and connections. The section explains how to make the settings for the N-410, BL/SR/RF Series devices, the NX50RS and the computer.
5-1 Multi-head Mode N-410 Settings Make the following settings in the AutoID Navigator. 1.Set the "BL Series Multi-head mode" and "RF Multi-head mode" settings under "Main setting" to match the network you are using. 2.Use the following settings for multi-head mode • Trigger notification method • Read mode • Data transmission timing • Trigger input measurement 3.Register the connection types and ID numbers of the devices to be connected under "Slave settings". 4.
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.

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.
5-2 Operating in Multi-head Mode 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.
5-2 Operating in Multi-head Mode Data Transmission Timing Select one of the following triggers to send data to the host computer. • After read Data is sent immediately after it has been read.

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.
6-2 Details of Data Communication 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 6 Read data Serial Communication N-410 • The read data is sent to the host computer constantly.
6-2 Details of Data Communication • The PASS and RTRY formats PASS CR , STX PASS ETX , are all possible. At the head of the command, ESC or at the end LF may be added. Note • 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.
6-2 Details of Data Communication Send Buffer Capacity of the N-410 Series The N-410 Series device 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 the error number "96" will display on the 7-segment. Send the cancellation command (OVCLR) from the host computer to the N-410 Series in order to cancel the buffer overflow error.
6-3 Command Communication with BL/SR/RF Series Devices Operational commands can be sent from a host computer to BL/SR/RF Series devices that are connected to the N-410 Series.
6-3 Command Communication with BL/SR/RF Series Devices This section describes command communication examples. (The N-410 Series is in the Auto-polling mode) [Example 1] The trigger input ON command (LON) is sent to the BL Series device that has an ID number 3 and data to read (KEYENCE) is received.
6-4 Direct Control Command of the N-410 Series The following controls are available by sending commands to the N-410 Series. • Registering the ID number of the BL/SR/RF Series device that is connected. • Turning the auto-polling on/off. • Checking the connection • Sending the read control command in multi-head mode. • Resetting the N-410 Series. Procedure for Command Communication 6 1 Send a direct control command from the host computer to the N-410 series.
6-4 Direct Control Command of the N-410 Series Details of Direct Control Commands Registering and checking an ID number for auto-polling. A direct control command allows for registering and checking an ID number for auto-polling. * Register a slave type to connect by using a setting command beforehand.

7-1 PLC Link A PLC link allows the N-410 to use the RS-232 interface to write directly to the internal memory (data memory, data register) of a PLC (programmable controller). No communications program is necessary for the N-410 to write directly to the PLC internal memory, so fewer man-hours are spent on programming. Important 7 There are several limitations when using a PLC link instead of serial communications. • RF-500/RF-550 devices cannot be connected to the N-410 when using a PLC link.
7-1 PLC Link Usable Devices Devices accessible via PLC link are those within the following ranges. Series Device range KV-10/16/24/40 KV-P DM0000 to DM1999 KV-700 KV-1000 KV-3000 DM0000 to DM9999 MELSEC Series D0000 to D8191 SYSMAC Series DM0000 to DM9999 Note 7 The range of devices compatible with individual PLCs may be smaller than what is listed above. Refer to the user’s manual of each device for more information.
7-2 Device Assignments Device assignments for multi-drop link mode and multi-head mode are different. This section explains those differences. Device Assignments for Multi-drop Link Mode The data range controlled by the N-410 includes the PLC internal memory. Set the device header address in the N-410 "PLC settings" for automatic assignment.
7-2 Device Assignments (Write location area for each ID number) Data write areas can be assigned as follows by assigning "+02 to +32" to the "write header address" (A). If there are 10 BL Series or SR Series devices connected, the following read data will be divided into 10 parts in and saved in 10 separate write areas. (This is the case if each ID number has a distinct data write header address).
7-2 Device Assignments Details of DM assignments This section explains assignments to each address. +00 BL Series buffer overflow notification This area contains notifications of buffer overflows on connected BL Series barcode readers. It normally contains "0000", but will be changed to "0001" if an overflow has occurred. It will return to "0000" when the code reader's buffer has been cleared. +01 Buffer overflow clear This area is used to clear buffers. This area should be written to with binary data.
7-2 Device Assignments Real time control • Write either 0000 or 0001 to this area. • This will be 0001 when the code reader is reading the barcode or the N-410 is writing to the PLC. • This returns to 0000 after data has been written so that new data can be written in the A+01 to +130 addresses. In other words, if the A+00 address contains 0000, the data is valid. (Example 1) The A+00 address is normally 0000.
7-2 Device Assignments A+01 to +130 Data write area (ID number, digits, data) • The A+01 address contains the ID number of the code reader that did the reading. The A+02 address contains the data size in binary. • The A+03 to +130 addresses contain the barcode or ASCII data (in two-space hexadecimal) that was read in. • The A+03 to +130 addresses for a single DM are written in high byte, low byte order.
7-2 Device Assignments Operation with connection errors and connection type errors When using the N-410 in multi-drop link mode and • the power to a code reader is turned off • the code reader is removed from its communication unit • a cable is removed • a device with a connection type other than that used by the N-410 is connected to the network • a communication error occurs the N-410 and code reader will be unable to communicate and operation will proceed as follows.
7-2 Device Assignments Device Assignments in Multi-head Mode This is the area where code data read in multi-head mode is written. Unlike multi-drop link mode, multi-head mode control multiple code readers as if they were a single device, so there is only one area that data is written to.
7-2 Device Assignments Real time control • Write either 0000 or 0001 to this area. • This will be 0001 when the code reader is reading the code or the N-410 is writing to the PLC. • This returns to 0000 after data has been written so that new data can be written in the +04 to +133 addresses. In other words, if the +02 address contains 0000, the data is valid. (Example 1) The +02 address is normally 0000.
7-2 Device Assignments +04 to +133 Data write area (ID number, digits, data) • The +04 address contains the ID number of the code reader that did the reading. The +05 address contains the data size in binary. • The +06 to +133 addresses contain the code or ASCII data (in two-space hexadecimal) that was read in. • The +06 to +133 addresses for a single DM are written in high byte, low byte order. When writing odd-byte data, the last digit (the low byte of the last piece of data) will be written as 00h.
7-3 Settings Refer to "2-1 Making Settings and Connections" (Page 2-2) for the procedure for making settings and connections. The section explains how to make settings concerning the N-410, BL Series devices and the PLC. BL Series and SR Series Settings (When Using an NR-4/N-48/BL-U1) 1. Set multi-drop to "Enabled". 2.

6 Calculating Checksums A checksum can be appended to read data as it is being transmitted (The checksum will not be appended to commands or replies). The checksum allows you to check if RS-232C communications have become corrupted. By using the PASS/RTRY or ACK/NAK protocols, an automatic RTRY or NAK can be sent if the checksum does not match. Settings should be handled through "Protocol settings" on the setting software (This cannot be done when using a PLC link).
6 Calculating Checksums Calculating Checksums Header % P mm - 0008 AB12 cc Delimiter will serve as an example in calculating checksums. The characters are converted to ASCII code and converted into 8 bit binary numbers as shown below. Each bit of each character is then fed to an Exclusive Or function.
7 Setting Item List The section shows the settings that can be made for the N-410.
