User’s Manual

1.1 Introduction

The GC-ATC-2000 is a RS232/RS485 to TCP/IP converter
integrated with a robust system and network management
features designed for industrial equipment to be accessed
and controlled via Intranet or Internet. By integrating RTOS
(Real Time Operating System) and complete TCP/IP protocol
stack capability, GC-ATC-2000 provides not only a robust
and high performance system to make your device
connecting to Network, but also ease installation and Internet
access.
The GC-ATC-2000 Web Configurator is a breeze to operate
and totally independent of the operating system platform you

The GC-ATC-2000 support four types of connection: TCP
server, UDP server, TCP client and UDP client, user can
select one of types to meet appl ication requirement.

►DHCP Client

DHCP (Dynamic Host Configuration Protocol) client obt ai ns
the TCP/IP configuration at start-up from a centralized DHCP
server, which means it can get IP address , an IP defa ult
gateway and DNS server.

►PPPoE Over Ethernet

PPPoE is a protocol for connecting remote hosts to the
Internet over DSL connection by simulating dial-up
connection.

►

Dynamic DNS

With dynamic DNS support, you can have a static hostname
alias for a dynamic IP address, allowing the host to be more
easily accessible from various locations on the Internet.
►Auto-negotiating 10/100Mbps Ethernet
The Ethernet interface automatically detects if it is on a 10 or
a 100 Mbps Ethernet.
►Full Network Management via Web
This feature allows you to access or manage device through
IE or Netscape on any platform. The firmware also can be

4.0 Configure your GC-ATC-2000
Use this section to set up your computer to assign it a static

IP address in the 192.168.168.1 to 192.168.168.254 range
with a subnet mask of 255.255.255.0. This is necessary to
ensure that your computer can communicate with your
GC-ATC-2000. Your computer must have an Ethernet card
and TCP/IP installed. TCP/IP should already be installed on
computer using Windows 98/2000/XP and la t e r opera t in g
systems.

Step 1：Open your web browser and type

http://192.168.168.125

in the browser’s address box. This
address is the factory set IP Address of your GC-ATC-2000.
Press “Enter”.

Step 2：The “Username and Password required” prompt

box will appear. Typing “admin” (default username) in the
Username field and typing “admin” (default password) in the
Password field. Click “OK”. The setup screen will then
appear.

This chapter will show you how to configure
GC-ATC-2000 to function in your network and gain
access to your device through Intranet or Internet.
