7.2.3 Exposure sequence (Commands EXSQ, PES(N), PER(N), EXSR, EXSEP, PE1
～
PE16)
Up to 16 exposure settings can be preset as a sequence. Each setting can also be repeated.
This function is effective only when the trigger mode is ON, the exposure mode is set to
Timed and the exposure sequence is ON.
7.3. Trigger Control
7.3.1 Selection of the trigger input (Command: TI)
The command “TI” can select the trigger input. At TI=0, the input through Camera Link
(line 0) is active and at TI=1, the input through the Hirose 12-pin connector is active. The
factory default setting is the Camera Link input.
7.3.2 Trigger activation (Command: TA)
The command
“
TA
”
can select how to activate the trigger.
TA=0
Rising edge
At the rising edge of the pulse, the accumulation and the
readout will start.
TA=1
Falling edge
At the falling edge of the pulse, the accumulation and the
readout will start.
If Exposure Mode(EM) is set to EM=2 Trigger Width)
TA=0 High
During the high level of trigger, the accumulation is activated
and at the low level, the read out is activated.
TA=1 Low
During the low level of trigger, the accumulation is activated
and at the high level, the read out is activated.
7.3.3 Trigger Overlap (Command: TO)
This function sets if a trigger pulse can be accepted while data is being read out or not.
TO=0
OFF
：
The trigger pulse is not accepted during CCD readout.
This works the same as the LVAL asynchronous mode.
TO=1 Read Out
：
The trigger pulse can be accepted during CCD readout.
If the trigger pulse is input during CCD readout, it operates as LVAL
synchronous and if the trigger is input while the CCD is not being
read out, it operates as LVAL asynchronous.
7.3.4 Pre-Dump (Command: TD)
The pre dump command has TD=0(disable) and TD=1(enable) modes.
This command can be used with EM=1 (Timed) and it operates the same as RCT mode.
If this mode is “enabled”:
Until the trigger is input, the camera operates continuously and the video signal for the
auto-iris lens is output. When the trigger is input, the fast dump is activated to read out
the electronic charge very quickly, after which the accumulation and the readout are
performed. When the signal is read out, FVAL , LVAL and DVAL are output too.
