misc 0 - NOT AVAILABLE BY
COMMAND.
ONLY FOUND in Conf
0 prog | fin
' ' | ovr Misc info
prog if the card is freshly
programmed by the bootloader and
the program is still un-finalized. fin is
the normal condition.
ovr if DIP-switch 16 is set to the ON
position and the card is under DIP-
switch control.
Note 1: The info part of misc has
additional functionality when locate is
used: locating <remaining seconds>.
This enables a visible countdown
clock in Multicon GYDA, but is not a
required part of FLP400.

pri: a prioritized list of inputs, used
when change-over is automatic. The
list can have 1, 2 or 3 entries, or
levels. Manual mode is effectively the
same as automatic mode with one
priority level only, but has its own
command.
0 = from electrical input
1 = from optical input
2 = internal video generator
3 = mute
4 = none
The module will always respond with
3 levels, filling in 4=none for the
levels not used.
latch: <latch_status> can be either
on or off and selects if the change-
over is latching or not, used when
change-over is automatic. Latch on
means that if we've lost our main
source and moved on to a lower
priority level, we'll not search to see if
the higher pri's will reappear.
rule: <rule> can be either los or lol,
which means loss off signal or loss of
lock. This determines what triggers
an automatic change-over.
t1 and t2: change-over doesn't
happen immediately, as a precaution
against glitches and unstable signals.
The timers t1 and t2 let the user
decide how long (in ms) we will cling
on to a missing input before we
consider it gone and move on to the
