edh 0 reset msk <24b_mask> Error detection and handling
Error counting. The count itself is
reported in info. Errors can be
masked off and not counted; this is
the purpose of the mask. The counter
itself is 16b and will wrap around, but
can also be reset by issuing reset.

iN Audio matrix
mtx 0 (size 10:10) controls the audio
matrix; outputs 0-7 are embedded
sound, 8=adac and 9=AES.
Note: Any combination of the three
basic commands are allowed, for
instance the following command to
set up a 10x10 audio matrix in a
single line:

cBFS Audio generator
The amplitude of the generated sine
that can be chosen as fallback in
audio change-overs. Legal values are
-180cBFS or -200cBFS (centiBel
referred to full scale output). Units
are optional, but if included must be
written as cBFS (case sensitive).

one block for each output from cho 2-

the lower 8 are routed to the
embedder. The meaning of the
commands are as follows:
lr = Normal
rl = Channel swapped
ll = Left channel to both output

rr = Right channel to both output

nlr = Left channel phase inverted
lnr = Right channel phase inverted
mm = Mono, both channels = (r+l)/2

Audio DAC control
This word dac identifies this audio
block as a DAC. The outputs can be
muted, given as on or
off, and the output level can be set in
cBu (tenth dBu). Units are optional, if
included must be written as cBu
(case sensitive).
Note 1: The lvl and mute are
independent, so that the card will
remember the lvl setting (and change
lvl setting) while muted.
Note 2: The resolution of the lvl
control is 0.5dB but the card will
perform correct rounding to nearest
legal value and report the resulting
setting. Legal input range is [-
