6.1.4 Electronic Shutter
CM-040MCL / CB-040MCL has conventional shutter functions such as preset shutter and
programmable shutter.
Preset Shutter
9 steps of preset shutter are available: OFF (1/61);
1/100,1/120,1/250,1/500,1/1,000,1/2,000, 1/4,000,1/8,000,1/10,000 sec.
Programmable Shutter
It is possible to set the shutter speed in the range of 2L to 596L by 1L unit, in the case of full
frame operation. When 596L is set, it is the equivalent of “OFF (1/61)“ or 16.353ms.
Pulse Width Control
When this mode is selected, the exposure time is controlled by the width of the trigger pulse.
The minimum trigger pulse width is equal to 1L (27.437µs) and the recommended maximum is
2 seconds.
6.1.5 Auto-Iris Lens video output (12-pin Hirose connector)
This analog signal is available at pin 4 of the 12-pin Hirose connector. It can be used for lens
iris control in continuous mode and RCT mode only. This output is always effective.
As the signal is taken after the CCD sensor output passes through the gain circuit, the gain
setting is influenced. The video output is without sync signal. The level is 0.7 V.
