8.3.5 Auto-detect LVAL-sync / a-sync. accumulation
This function replaces the manual setting found in older JAI cameras. Whether accumulation is
synchronous or a-synchronous 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 trough in the video signal. There is a maximum jitter of
one LVAL period from issuing a trigger and accumulation start.
If trigger is received when FVAL is low, the cameras works in LVAL-asynchronous mode (no delay)
mode. This applies to both pre-select (PS) trigger mode and pulse width trigger (PW) mode.
Ext. trigger
FVAL
(1) In this period camera executes trigger at next LVAL (prevents feed-through noise)
(2) Avoid trigger at FVAL transition (+/- 1 LVAL period), as the function may randomly switch
between "next LVAL" and "immediate".
(3) In this period camera executes trigger immediately (no delay)

8.3.6 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
Ethernet Connector indicates,
Steady Green: 1000 Base-T has been connected
Flashing green: 100 Base-T has been connected (Note)
Flashing amber: Network active in communication
Note: When 10 Base-T is connected, the green is flashing.
However, the video is not streamed through Ethernet.
