defpre (default preset)

This command may be used as a query to determine
the memory preset location used as the powerup
default. It may also be used as an update to set the
default preset. The data is an integer type in the range 0
to 24, where 0 has the special meaning "On powerup,
the preset that was active when the unit was last
powered down will be recalled". This provides a
"memory" capability useful for some applications, and is
called the Last Preset option.
Examples:
REQUEST
QUERY
defpre?<CR>
UPDATE
defpre=2<CR>

desc (description)

This command may be used as a query to read the
user defined device description. It may also be used as
an update to set the description. The data is a string
type, with a limit of 32 characters.
Note: String arguments in commands need to be
passed in quoted form, contained in a pair of
double-quote (") characters. A problem arises
when using the desc command to read or write a
string that already contains double-quote
characters, for example: The "Hula" Room. The
solution is to escape the double quotes within The
"Hula" Room so that it can be passed as a string
argument for the desc command. This is done by
preceding the double-quote characters with a
backslash character like this: The \"Hula\" Room.
Now it can be passed as a string argument to the
desc command: desc="The \"Hula\" Room". Since
the backslash serves as the escape character in
quoted-string arguments, it too must be escaped if
it is part of the string, so "foo\bar" would become
"foo\\bar"
Examples:
REQUEST
QUERY

desc="Courtroom

Rio Rancho, NM

fpgnran (front panel control gain range)

This command may be used as a query to read the
Front Panel control gain range, or as an update to set
the gain range. The gain controls are addressed as a
single group of 12 with addresses 1 - 8 used for the 8
input channel gain knobs, and addresses 9 - 12 used
for the 4 output channel gain knobs. The gain control is
specified by using the address syntax. Addresses must
be in the range 1 to 12. The data type is integer, in the
range 6 to 40, representing the range of gain in dB,
centered on 0 dB. For example, if 30 dB is specified, the
result is a range of gain control from -15 to +15 dB. If
the channel address is wildcarded, then the data type is
an array of integer of size 12. In this case the value 99
may be used in an update to indicate that a particular
input gain is to remain unchanged by the command.
Examples:
REQUEST
QUERY
fpgnran(1)?
<CR>
QUERY
fpgnran(*)?
<CR>
UPDATE
fpgnran(5)=30
<CR>
UPDATE
fpgnran(*)=
{40,40,
20,...,20,99,
99}<CR>

fplock (front panel control lock)

This command may be used as a query to determine if
the DM84 Front Panel gain controls are locked (dis-
abled) or unlocked (enabled). It may also be used as an
update to lock or unlock the controls. The gain controls
are addressed as a single group of 12 with addresses 1
- 8 used for the 8 input channel gain knobs, and ad-
dresses 9 - 12 used for the 4 output channel gain
knobs. The gain control is specified by using the ad-
dress syntax. Addresses must be in the range 1 to 12.
The data type is integer, either "1" meaning that the
input is locked (disabled), or "0" meaning that it is not. If
the channel address is wildcarded, then the data type is
an array of integer of size 12. In this case the value 99
may be used in an update to indicate that a particular
input gain is to remain unchanged by the command.
