The temperature of the SFP and the FPGA and the voltage of several power rails on each
board are monitored, and can trigger alarms if they fall outside their respective limits. These
limits can be seen in the alarm section of the Configuration page. The alarms themselves are
a feature of Multicon, please refer to the Multicon user manual.
In the graphical representation of the board there are three red crosses representing the mux
inputs and the three red crosses representing the de-mux outputs that have no signal. This
information is also available in the table representation of the board, where input BNC
numbers 2, 5 and 8, and output BNC numbers
4, 6 and 7 indicate “Loss of signal”. The
channels that do have a recognizable video format will indicate the video format present, as
shown for input BNC 1 and output BNC 3. This is also shown in the table part of this
illustration, where
the lock bit error is removed and the video format “576/25i” is stated for
these channels. In the event that an unknown format is present, this is indicated as
“Unknown” but still be transported if possible.
The matrix below the graphical representation of the board shows which output signals have
been connected to each of the input signals. This can be set in the configuration settings,
and any combination is possible, meaning one input signal can be routed to many output
channels.
Each channel also has its own error bit indicators. The boxes that have a red background
color indicate an error that is currently detected and counted. A green background will
indicate that the particular error is set to be counted, but that the error is currently not
detected. Errors that are not to be counted (i.e. set to “Ignore'” will be presented as the error
bit name on a gray background color (no example shown here), regardless if the error is
currently detected or not. Error types that are not supported for that particular channel will be
shown as blank boxes with gray backgrounds. Most web browser will expand the boxes that
contain text at the expense of these blank ones, as the example above shows.
