1-1 What You Can Do with the N-410
N-410 Overview

 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.
• This cannot be connected to RF Series devices.
• 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.

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