RitaBrowser monitors and controls Internet appliances built with Rigel
Corporation's RITA family of control boards.
The RITA nodes may be on the Internet or on a private network such as a
personal network or a company intranet.
There are two sets of information,
which must be specified.
Information about the PC you use to
run the RitaBrowser
To talk to the Rita board on the Internet you need
to know the IP address of the PC you are using . You must be on the
Internet to do this. The RitaBrowser will automatically check your PC
and report the IP address of your computer. The
“Port” address determines the UDP port your PC uses to communicate with
the RITA node. Unless you are
using this value in the RITA program, you may click the “Auto” box.
Information about the RITA nodes
The “Rita Nodes” tab in the configuration dialog lists the current
nodes. You may add, modify, or remove nodes from the list.
When adding new nodes, you will be asked to provide a name along with
the IP address and port number for the RITA node.
The name is used by the RitaBrowser to identify the node.
This is like the a “bookmark” or a “favorite” entry in a web
browser. The default RITA port
number is 8192 (0x2000). You may
change this number, especially if you intend to use it to identify among
various services at the RITA node.
You may save the list of RITA nodes
to a file as a backup or to load onto another PC.
When loading a RITA nodes list, you will be asked if you would like to
append the new list to the existing one or to replace the existing list with
the new list. In the former case,
you will also be notified if there are duplications or conflicts.

A list of currently known RITA nodes appears in a
drop-down list box. Select the
node you would like to communicate with and click the “Connect” button.
RitaBrowser opens a socket to communicate with the RITA node.
If the socket cannot be opened, it usually means that your PC’s IP
address is incorrect or you are not connected to the Internet. You
can run the RitaBrowser again which will automatically give you the IP address
of your computer. (You can double check this if needed. If
you are using a dial-up service, you can obtain the IP address by the “ARP”
utility. Open a DOS box and type
“arp –a” to see your assigned IP address.
If your PC is set to participate in a LAN, use the “Settings /
Control Panel /Network” dialog to view your IP address.)
Once a socket is successfully opened, you may type in the edit window and
communicate with the RITA node. Note
that the communication depends on the specific program running on the RITA
node. Being an open architecture,
you are free to program the RITA node any way you wish.
For instance, you may restrict the node to answer only to specific IP
addresses, or use the port numbers to invoke different behaviors.
Refer to the RITA hardware and programming manuals for further
information and demo programs. It is recommended that a RITA node responds with a short
message, possibly a menu, when it receives an unknown command or the question
mark ( ‘?’).
You may automatically launch programs on your PC when a keyword or alarm is
received from a RITA node. To do this enter the (case sensitive) keyword
and select the program to be activated. Note
that the parameters received from the RITA node following the keyword are
passed on to the launched program as command line parameters.
