400 Series MEI Device Servers

Features and Benefits

When you need the ultimate in device
server performance, ease of use and
flexibility, specify the new 400 Series
from Quatech, featuring an elegantly
designed multi-electrical interface (MEI).

Quatech MEI device servers are the fastest
and easiest way to connect RS-232, 422 or
485 devices to a local network or the Internet.

An intuitive Installation Wizard gets y ou
up and running in just minutes,
automatically searching local

and

remote

subnets for the correct model attached.
Network settings automatically assigned

by DHCP networks are displayed for
confirmation, or change to a static IP
address easily using the Installation
Wizard – you won’t have to bother with
telnet sessions, MAC address data entry
or special cables.

Quatech device servers may be
managed through the Windows® De vice
Manager interface or a W eb browser , so
you can count on trouble-free
configuration and maintenance long after
the initial installation is completed.

The 400 Series of device servers is now
offered in 1, 2, 4 and 8-port
configurations; a 16-port model is
coming soon.

Why Network A Serial Device?

Serial (RS-232/422/485) protocols are
a mature and reliable form of data
transfer , used in millions of products in
industries as diverse as:

Industrial Automation
CNC/DNC Applications
Banking & Finance
Energy Management
Security & Access Control
Government and Defense
Material Handling/Logistics

I Intelligent T r affic Systems
Yet, while serial protocols have prov en

to be reliable and robust, there are
drawbacks – cable lengths are limited
and expensive , COM ports are often in
short supply on the host PC, and the
attached serial devices are not remotely
accessible for monitoring, service or
support.

Quatech device servers help overcome
all these limitations. Its hardware and
drivers are invisible to connected serial
devices and their software applications,
routing data through “virtual” COM ports
added to the host PC by the Installation
Wizard. Within minutes, anyone with
proper authorization can access a serial
device over a LAN, an Intranet or even
the Internet!

The 400 Series models introduce a new
software-selectable Multi-Electrical
Interface to the Quatech product line.
Unlike many competing device servers
on the market, Quatech offers MEI
capability on all ports at the click of a
mouse. LEDs visually tell you which
ports are using which protocol, so go
ahead, mix and match. Already the
performance leader, Quatech has
become the flexibility leader as well.

Includes the fastest and easiest
Installation Wizard available

A built-in Web server makes
configuration and support
available via Web browser

Serial baud rates to 921kbps and
auto-negotiating 10/100 Ethernet
support means fast serial and
network data transfers

Your choice of local COM port
emulation, serial tunneling,
broadcasting, multicasting and
Raw TCP/UDP modes allows true
flexibility when integrating into a
variety of applications and
operating systems

FreescaleTM architecture is the
industry standard in networking
solutions

A PowerPC® processor
eliminates data bottlenecks and
common latency issues

IntelliSock™ mode provides
unique and powerful TCP socket
services for custom applications

SNMP support for simple
network management

Backed by a 5 Year Limited
Warranty and the industry’ s best
customer support team

Designed, manufactured and
supported in the USA
