RC2000 Web Server User’s Manual 1
1.0 THEORY OF OPERATION
1.1 User Interface Overview
The RC2000 Web Server allows control of the RC2000 by using a web browser. A built-in HTTP
server communicates with the RC2000 using an internal serial port. The server allows control and
feedback of the current controller operation using a web-based user interface. Detailed information on
the use of the main user interface is given in section 3.1 of this document.
1.2 Ethernet-to-Serial Overview
The RC2000 Web Server also provides an ethernet-to-serial connection. The entire RC2000 remote
control protocol can be used by encapsulating regular serial messages within UDP datagrams. The
corresponding replies are returned in similar fashion. Detailed information on the use of UDP
encapsulation is given in section 3.3 of this document.
2.0 CONFIGURATION
2.1 Physical Interface
The RC2000 Web Server comes in a 4.25” x 3.5” box that mounts using standard rack holes. The box
has four indicators to show network and serial port status and activity.
The connection from the target PC or other web-enabled device to the web server should be done
with a suitable CAT-5e cable. Depending on other equipment in the network, a cross-over cable may
be required.
The connection from the web server to the RC2000 is illustrated in the following drawing:
2.2 Network Settings
The PC or other web-enabled device and the web server must be properly configured to exist in the
same subnet in order to communicate with each other. Ask your system administrator for the subnet
mask and a unique IP address, and then configure the web server to that subnet and IP address
before connecting it to your network. Specifics on what IP addresses exist within any given subnet
and/or how to configure a particular device is outside the focus of this document.
All web servers are factory configured to have an IP address or 192.168.1.1 and a subnet mask of
255.255.0.0. Changes to the IP address or subnet mask can be made from within the configuration
interface. Setting the IP address of the target device to 192.168.1.2 with a subnet mask of
255.255.255.0 will usually allow a quick connection to the web server.
