Accessing the Web Server
To access the RBMS Plus Web page type your RBMS Plus’ IP address in the format “http://192.168.0.18” from your web
browser. This IP address is an example; substitute your RBMS Plus’ IP address in place of “192.168.0.18”.
4.9.2.
Ports
The RBMS Plus web server uses Ports 80 and 30704 to receive requests from the PC. The ports on the PC are selected
automatically. Port 80 is the normal HTTP port. Port 30704 is used by the Java applet to get data from the RBMS Plus
for the real time screen updates.
The transaction goes something like this: When the web browser is opened, the PC assigns an outgoing port X and
sends a request to port 80 on the RBMS Plus. The RBMS Plus replies with a response to the PC sent to port X. The Java
applet opens a connection on PC port Y to request the real time data and sends this request to RBMS Plus port 30704.
The RBMS Plus responds to PC port Y with the requested data.
Both ports X and Y are selected by the PC. These ports may be mapped to other ports by routers in the communication
path. This does not cause any problems since the RBMS Plus always responds to the port specified in the request.
If the web page draws but the applet is unable to connect to the RBMS Plus, chances are good that port 30704 is being
blocked by a firewall or router. This could be on your PC or somewhere in the network. Consult with your IT people to
find the problem.
Navigating the Web Pages
NOTE:
The RBMS Plus web page uses a Java applet communicating on UDP port 30704 to deliver real time
information. If you have trouble viewing the web page, this port may be blocked, so contact your IT
department.
The status of the batteries that are being monitored by an RBMS Plus can be viewed using any network-connected PC
that has a web browser.
