Adjusting the Pulse Width for External Output Ports in [AUXOUT1] or
[AUXOUT2]
– [PULSE]
This setting is unnecessary if [STATUS STANDBY], [STATUS TRIG], or [STATUS
REC] is selected as the external output port mode in [AUXOUT1] or [AUXOUT2] –
[MODE].
This setting outputs signals via external output ports with a pulse width specified in
[AUXOUT1] or [AUXOUT2] – [PULSE]. Settings are specified at 10 ns intervals
between 50 ns and 10,000,000 ns.
When the pulse width is short or a long cable is used, output signal waveform may be deformed,
hindering correct operation. In this case, adding a terminator may improve the condition though it
reduces voltage magnitude.

Selecting the Video Output Mode
– [VIDEO]
Two video output modes are available – either "NTSC" or "PAL" output. In the [VIDEO]
field, select either [NTSC] or [PAL].

Adjusting Exposure
To adjust exposure, follow the procedure below and use the internal trigger mode
[Internal].
1.
Set up and switch ON illumination.
2.
In recording parameter settings, change the recording mode in [REC]
– [MODE]
to the internal trigger mode [Internal].
3.
Click [REC] in the application.
Recording starts immediately and the image specified in "Selecting First Frame to
Display" in 5.5 Playing Back Images, is displayed in the Viewer window.
4.
Adjust the illumination, lens aperture, and exposure time while looking at the
image until a suitable exposure is obtained.
5.
If necessary, refocus the lens after adjusting the lens aperture.
Repeat steps (3) to (5) until a suitable exposure is obtained.
Similar adjustments are possible in the external trigger recording mode but a trigger
is required to record images.
