rprest (restore rear panel settings)
This command may be used to restore the state of rear
panel settings previously saved with the rpsave com-
mand. If used as a simple command, all rear panel
settings are overwritten with the saved values. If used as
an update, the data type is an integer whose value
serves as a mask which specifies which settings are
restored and which are not. This mask has the same
format as the
preset mask.
Example:
REQUEST RESPONSE
COMMAND rprest OK
UPDATE rprest=1 OK
rpsave (save rear panel settings)
This command may be used to save the current rear
panel settings so that they can be restored at some
future time by use of the rprest command. In this way a
“snapshot” of the current rear panel gain and mute
settings can be taken prior to some temporary
reconfiguration of the device.
Example:
REQUEST RESPONSE
COMMAND rpsave OK
Serial Interface & Control Commands (cont'd)
DM1624 ADFE Commands
adfeen Automatic digital feedback elimination enable
adfefil Automatic digital feedback elimination filter
deployment
adfeen (adfe enable)
This command may be used as a query to read the adfe
enable status, or as an update to set the status. The
audio input channel is specified by using the address
syntax. Addresses must be in the range 1 to 16. The
data type is integer, either “1” meaning that the adfe
feature is enabled, or “0” meaning that it is not.
Examples:
REQUEST RESPONSE
QUERY adfeen(9)? OK 1
UPDATE adfeen(11)=0 OK
adfefil (adfe filter deployment)
This command may be used as a query to read the adfe
filter deployment status, or as an update to deploy an
adfe filter. The input channel and filter index are speci-
fied by using the 2 dimensional address syntax. Ad-
dresses for the first dimension (input channel) must be
in the range 1 to 16. Addresses for the second dimen-
sion (adfe filter index) must be in the range 1 to 6. The
data type is integer, unless the adfe filter index is
wildcarded, in which case the data type is an array of
integer of size 6. This is allowed for queries only. The
data values are in the range 0 to 95, where 0 means
that no filter is deployed, and the others represent adfe
filters covering the frequency range 105 to 9773 Hz. See
the
table below.
Examples:
REQUEST RESPONSE
QUERY adfefil(9,2)? OK 0
QUERY adfefil(11,*)? OK {12,0,0,0,0,0}
UPDATE adfefil(4,1)=15 OK
