6.1.6 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 a 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 issuing a trigger and accumulation start.
When a trigger is received while FVAL is low, the camera works in LVAL-asynchronous mode,
(no delay) mode.
This applies to both edge pre-select (EPS) trigger mode and pulse width trigger (PWC) mode.

6.1.7 Rear panel indicator.
The rear panel mounted LED provides the following information:
Power /Trig LED
Amber: Power connected – initiating
Steady green: Camera is operating in continuous mode
Flashing green: The camera is receiving an external trigger

FVAL
(1) In this period camera executes trigger at the next LVAL. (Prevents feed-through
noise)
(2) Avoid trigger at FVAL transition (+ / - 1 LVAL period), as the function may randomly
switch between “next” and “immediate”.
(3) In this period camera executes trigger immediately. (No delay)
