1. Introduction
NS-105 Industrial Switches are DIN-Rail mounting and designed
for industrial environments. Their rugged packaging and protected
circuitry keep them working under conditions that may cause office-grade
units to fail.
Industrial Ethernet applications are demanding - This 5-port Fast Ethernet
switch become the basic unit of the whole Ethernet network. It is also the
good companion of our I-7188EX and I-8000 ethernet embedded
controller. The NS-105 comes with multiple ports, each capable of
transmitting or receiving information simultaneously at full wire speed to
control and allocate the network bandwidth. Besides that, the NS-105
Industrial Ethernet Switch automatically determines and remembers
where an Ethernet device is located and routes the messages only through
the appropriate port. This minimizes network loading and enables true
deterministic communications over Ethernet

The key features of this switch unit are:
z Optimized Bandwidth : Combining five 10/100Mbps-based Fast
Ethernet switched ports, the switch delivers a high network
bandwidth for your Fast Ethernet network
z Easy Migration : With 10BASE-T support on each port, the switch

provides a non-disruptive and smooth migration path from Ethernet
to a Fast Ethernet network.
z Easy Installation : With the functions of auto-speed-sensing and
auto-negotiation on each port, the switch supports plug-and-play
installation which eliminates configuration problems.
