FM-531HD / May 2013
F M - 5 3 1 H D G U R U G U I
The FM‑531HD’s TCP protocol utilizes a fixed port, port
55900 for control. The
FM‑531HD uses UDP for metering and tries to open port
60000
first. If port
60000
is not busy, it uses it. If UDP port
60000
happens to be busy, UDP port
60001 is tried
next. This process continues until either an idle UDP port is found or the search stops
at UDP port
60010.
NOTE:
The above reference ports must be open for any through‑the‑firewall con
-
nectivity. This also includes the Windows firewall on the host PC that is running the
GUI software – it must have these ports open too.
If the GUI Is “Connected” But the Meters and Analysis
Displays Don’t Work
Occasionally a network or internet service provider will block UDP traffic. When
that happens the GUI will connect to the FM‑531HD and the FM‑531HD can be con
-
trolled, but no metering or analysis graphics will be displayed. Fortunately we have
provided an easy workaround:
Navigate to the GUI’s System screen and check the box labeled
Metering data
over TCP/IP
and the issue should be solved. Note that choosing the TCP protocol for
metering will increase the amount of network traffic because now every metering and
analysis packet requires a handshake to ensure its integrity. The poorer the network,
the more bandwidth the GUI will try to use (a poor network implies the need for more
handshaking to ensure good data).
