932502G / 0618 7. FIRMWARE COMMANDS AND RESPONSES
the zero peak is 3 channels, and the absolute maximum width for the zero peak is 256 chan-
nels in Gauss mode. In point mode there is no maximum peak width, though the chosen
width must allow the peak to fit within the device’s channel limits as stated above.
Non-USB Execution Errors:
%131128085<CR> The specified number of channels would create a peak that
was less than the minimum width (3 channels) or would be
outside the devices range.
%131136084<CR> The command was attempted while zero stabilization was
enabled.
SHOW_ACTIVE
Returns a 1 if the DSPEC 50 is active (i.e., acquiring spectral data) or 0 if it is not active.
Responses:
$C00000087<CR> Not active.
$C00001088<CR>
Active.
SHOW_BLRE
Shows the baseline restorer time constant in microseconds. See also SET_BLRE.
Responses:
BLUE 000000000000091 Time constant is 91 ìs.
SHOW_BLRE_AUTOMATIC
Shows whether automatic selection of the baseline restorer constant is off or on.
Responses:
$IT<CR> Automatic baseline is enabled.
$IF<CR> Automatic baseline is disabled.
SHOW_CONFIGURATION
Returns a record that indicates the hardware configuration of the MCB. The record contains
information about the number of segments in an MCB device (always 1 for the DSPEC 50),
and the current conversion gain for each segment. The record is organized as follows:
$J1638400001aaaaa00000[65 zeros here for total of 75 zeros]00000ccc
where aaaaa represents the conversion gain for the one and only segment in the currently
selected device, and ccc represents the record checksum. See the section on response records
in this chapter for more information about response records and checksums.
SHOW_CONFIGURATION_MASK
Returns two masks, the first of which can be “anded” with data from the MCB to clear the
ROI bit from the data. When the second mask value is “anded” with data from the MCB, the
data bits are removed and only the ROI bit remains.
