Electronic Shutter
The CM/CB-140 MCL ,CM/CB-140PMCL and CM-140MCL-UV/PMCL-UV allow selecting shutter speed
in two ways; preset shutter (10 fixed steps) and programmable exposure (in 1051 line period, LVAL,
increments).
Preset Shutter
The following shutter speeds can be selected by command SH=0 through SH=9.
OFF (1/31), 1/60, 1/100, 1/250, 1/500, 1/1000, 1/2000, 1/4000, 1/8000, 1/10000 seconds
Note: UV version is OFF (1/16), 1/30,1/60, 1/100, 1/250, 1/500, 1/1000, 1/2000, 1/4000, 1/10000 seconds
Programmable Exposure (PE)
The exposure time can be programmed in 30.58µs (LVAL period) increments. The range is from 2
LVAL to 1051 LVAL.
Minimum exposure time 2L
Maximum exposure time 1052L
30.584µs x 2(L) = 61.168 µs 30.584µs x 1052 (L) ≈ 32.17ms
MCL/PMCL
58.9µs x 2(L) = 117.8 µs
58.9µs x 1052 (L) ≈ 61.92ms
UV version
In V binning mode:
Minimum Exposure time 2L
Maximum exposure time 527L
38.83 µs x 2(L) = 77.66 µs
38.83 µs x 527 (L) ≈ 20.46 ms
MCL/PMCL
74.793 µs x 2(L) = 149.58 µs
74.793 µs x 527 (L) ≈ 39.4 ms
UV version
6.1.3.
Continuous operation or triggered operation
The camera can operate in continuous operation applications not requiring asynchronous external
trigger. This mode permits the use of a lens with video controlled iris. The camera will operate at
its maximum frame rate, 31 frames/seconds (16 frames /second for UV) in this mode.
For applications that require an external trigger, the camera can accept an external trigger input
on pin 10 of the 12-pin Hirose connector or via the Camera Link interface. The command "TI" is
used to switch between inputs.
The camera can operate up to 30 frames/second (16 frames /sec. for UV)in triggered operation.
6.1.4.
Iris video output.
The iris video output in pin 4 on 12-pin HR is 700 mV for 100% video
out in Camera Link. The iris video signal is taken before the gain
circuit. It is without sync.
The iris video signal can be used for auto iris lens drive in
continuous mode.
NOTE:
In the PoCL version this function is not available.

Rear panel indicator.
The rear panel mounted LED provides
the following information:
Amber:
Power connected - initiating
Steady green:
Camera is operating in Continuous mode
Flashing green:
The camera is receiving external trigger
