Resolving Common Problems
1.
Problem - The RBMS Plus resets approximately once an hour. Background – The RBMS Plus updates its real-time
clock from a network time server approximately once per hour. If the RBMS Plus is unable to communicate with
the time server, it will reset in an attempt to restore communications. Solution – First check if the RBMS Plus is
obtaining the time by looking at the time display above the Telnet setup menu. If the time is correct, the RBMS
Plus is communicating with the time server and the time server is not the cause of the resetting. If the time is
incorrect, verify that the time server IP addresses are correct and that port 123 is not being blocked by a firewall or
router. Verify that the reset is being caused by no time server communications by setting the IP address of the first
time server to zeros from the setup menu. This will disable the time server reset. Verify that the time server IP
addresses are correct.
2.
Problem – The web page opens but does not connect to the RBMS Plus. No real-time information is displayed.
Solution – This problem occurs when UDP port 30704 is blocked by a firewall or router in the network. The Java
Applet running on the PC will send message to RBMS Plus UDP port 30704 to obtain the data required to update
the web pages. Consult with the IT department to determine where this port is being blocked. To verify the web
server in the RBMS Plus is functioning, set the RBMS Plus to a static IP address and set your PC to this a1.
Connect the RBMS Plus Ethernet connection directly to the PC Ethernet using a crossover cable. If the web page
can be opened and updated when connected this way the web Server is working properly and the problem is in
the network.
