ALC Speed:
Rate of adjustment can be set (Common with Gain auto)
Exposure Auto Max:
The maximum value for the exposure time to be controlled can
be set
Exposure Auto Min:
The minimum value for the exposure time to be controlled can
be set
ALC Reference:
The reference level of the exposure control can be set
(Common with Gain auto)

7.3. Trigger Mode
7.3.1 Trigger Source
The following signals can be used as the trigger source signal.
OFF
Line 4 (Input to TTL In 1 and output from Digital IO)
Line 7 (Input to CL CC1 In and output from Digital IO)
7.3.2 Trigger Activation
This command can select how to activate the trigger.
Rising Edge:
At the rising edge of the pulse, the trigger is activated.
Falling Edge: At the falling edge of the pulse, the trigger is activated.
Level High: During the high level of trigger, the accumulation is activated
Level Low:
During the low level of trigger, the accumulation is activated
If Exposure Mode is set to Trigger Width, Level High or Level Low must be used.

7.3.3 Trigger Overlap
This function defines whether or not a trigger pulse can be accepted while data is being
read out.
OFF
:
The trigger pulse is not accepted during CCD readout.
Read Out
:
The trigger pulse can be accepted during CCD readout.
7.3.4 Trigger Delay
This function is used to delay the trigger signal against the trigger input signal.
The step of the delay is 1
μ
sec.
The setting range:
0 to 0.65,535
μ
sec (16-bit)
7.4. Normal continuous operation (Timed Exposure Mode/Trigger Mode OFF)
This is used for applications which do not require triggering. In this mode, the video signal
