Immediate read out mode (default, srm 2)

In this mode the image is read out, including accumulated dark current, immediately
following the trigger or the EXSYNC falling edge.
There are no line rate limitations other than the amount of gate dark current that can be
tolerated at low line rates.
There are no timing or exposure anomalies other than situations where EXSYNC is
removed from camera. In this case, the camera will operate in a "watchdog" state.
For information on artifacts that may be experienced while using this mode, see the
Artifacts section below.

Gate dark current clear mode (always on, srm 1)

In this mode the gate dark current will be cleared continuously.
After the trigger (EXSYNC) is received, the dark current is cleared from the image sensor
before the image is acquired. The line rate is limited to ½ the maximum line rate available
for that model of camera.
For information on artifacts that may be experienced while using this mode, see the
Artifacts section below.

When operating in the dark current clear mode, there will be a slight delay,
equivalent to one readout time, before the actual exposure is implemented. The
actual exposure time will not be altered.
