Full Name
DEK
Mnemonic
Mode
Argument(s)
Allow the use of the Esc key to be disabled so that upon boot-up the camera will directly enter
Description
the ASCII command mode. With the Esc key disabled the GENCP cannot be accessed.
Notes To access the GenCP, you have to first issue the DEK 0 command in order to enable the
ESC key. Then reboot the camera.
Full Name Device Scan Type
Mnemonic DST
Argument(s) Mode
Description Use this command to switch between Area and Single Line modes.

Notes
Perform flat field calibration using the average of <# lines>.
With filter algorithm this average line is then smoothed and outlier pixels are
interpolated. Use this feature if your white reference is not featureless.
Adjust pixel gain such that output will be <target>.
The target is first divided by horizontal binning factor and gain and then the
offset is subtracted. Therefore the output will go to the target.
Because the PRNU can be less than 1, the target may be below the current
maximum value.
Coefficients are saved and loaded with user set (e.g. USS / USL)
STG must equal 1 to enter the area mode DST = 1
