Triggered Control mode
7.3.3.
In triggered control mode (MO3), the acquisition is started by a hardware trigger. The length of the
exposure is determined by camera parameter IT.
Image Acquisition commands

Camera acquisition mode
7.4.1.
The camera acquisition mode is set by the MO command.
Command format: MOx
Command format: MO?
Return Message: x
where x is one of the values shown in the table below. Other values for x are not allowed.

See chapter 7 Acquisition Modes for a description of each mode.
Integration time
7.4.2.
The integration time in continuous mode is set by means of the IT command.
Command format: ITx
Command format: IT?
Return Message: x
where x is the integration time in units of 1 µs. The minimum allowed value for x is 1 and the maximum
value allowed for x is 100000 (= 100 ms).
The sensor design dictates a minimum integration time, Imin. This is not included in the ITx command
and will be added to that set value.

Values of Imin Time for different cameras.
Table 7.7:
Continuous mode:
Actual_integration_time = x + Imin.
Normal control mode:
Actual_integration_time = cc1_pulse_ Imin.
Syncontrol mode:
Actual_integration_time = Frame_time; Latency of Imin.
Triggered Mode:
Actual_integration_time = x + Imin.
The camera automatically checks the specified integration time. When the set value of IT is too large
for the current frame period time, the integration time is limited to the maximum possible value, which
is the value set by the FP command minus the value in table 7.1.
