Electronic Shutter
The AM/AB-1600CL allows the shutter speed to be selected in two ways; preset shutter (10 fixed
steps) and programmable shutter (up to 3248 line periods, 1 LVAL increments).

Programmable Shutter
The exposure time can be programmed in 98.66
µ
s (LVAL period) increments. The range is from 3
LVAL to 3248 LVAL. OFF is 3327L. L=LVAL.

Continuous operation or triggered operation
The camera can be operated in continuous mode for applications not requiring asynchronous
external triggering. The camera will operate at its maximum frame rate, 2.99 frames/seconds, in
this mode.
For applications that require an external trigger, the camera can accept external trigger input on
pin 10 of the 12-pin Hirose connector or via the Camera Link interface. This can be selected via
serial interface.

Rear panel indicator.
The rear panel mounted LED provides the following information:
Amber and Red: Power connected – initiating OS
(approx. 20 sec.)
Red:
Initiating the application (approx. 10sec.)
Steady green:
Camera is operating in Continuous mode
Flashing green:
The camera is receiving external trigger
Note: When the camera is receiving the external trigger in
Continuous mode, the LED does not flash.
The LED flashing indicates incoming trigger but not the
trigger duration.
6.2.5.
Auto-detect LVAL-sync / async accumulation
This function replaces the manual setting found in older JAI cameras. Whether accumulation is
synchronous or asynchronous in relationship to LVAL depends on the timing of the trigger input.
When trigger is received while FVAL is high (during readout), the camera works in LVAL-
synchronous mode, preventing reset feed through in the video signal. There is a maximum jitter of
one LVAL period from the start of a trigger to the start of accumulation.
When the trigger is received and FVAL is Low, the camera operates in LVAL-asynchronous mode
(no delay) mode.
This applies to both pre-select (PS) trigger mode and pulse width trigger (PW) mode.
