Figure 3: An overview of the de-mux configuration page
3.1.1 Laser on/off (mux side only)
The laser on/off setting is only found on the mux side. The video transport from mux to de-
mux will obviously not work when the laser is switched off, and this setting is primarily
intended as a safety feature when work is being done on the rear of a live Flashlink rack. A
GPIO input line is also available to disable the laser, see chapter 3.3.
3.1.2 Sticky vs. Normal error indication
When errors are detected and counted they are indicated on the Multicon Info page by red
background in the corresponding error box. Default behavior (Normal error indication mode)
is to accumulate error types between each time Multicon asks for status.
Due to the internal architecture of Multicon it is possible that errors will occur and the error
counter increase without any error bits being shown as red on the information page. The
processes that retrieve information from the cards are not synced up to the processes that
display the results to multiple users/clients. What this means is that short-lived errors may
turn up and disappear again between two web browser updates for a certain client. The
error will be counted, but the operator may never see any indication of what kind of error
that occurred.
For errors that occur very infrequently it is also inconvenient to sit around and wait for them
to happen, but it would still be interesting to know what type of error it was.
