N-410 Overview

1-1 What You Can Do with the N-410
The N-410 allows you to add the following functions to any BL/SR/RF Series device.
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.
• BL Series, SR Series, and RF Series devices cannot be connected at the same time in
multi-head mode.
• An NX-50RS Series device cannot be connected to an SR-600 Series device.
