Auto Iris Lens video output (12-pin Hirose connector)This analogue signal is not routed through the GPIO.This signal is available at pin 4 of 12-pin Hiroseconnector. It can be used for lens iris controlin Continuous mode only.The signal is taken from the CCD sensor outputbefore the gain circuit. The video output iswithout sync. The signal is 0.7 Vpp from <400 Ω Fig. 13. Video output circuit.AC coupled.To get this signal, the internal DIP switch must be setas follows.Fig. 14. Iris video output.8.3.5 Auto-detect LVAL-sync / a-sync. accumulationThis function replaces the manual setting found in older JAI cameras. Whether accumulation issynchronous 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-synchronousmode, preventing reset feed trough in the video signal. There is a maximum jitter of one LVAL periodfrom issuing a trigger and accumulation start.When 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. triggerFVAL(1) (3)(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 switchbetween "next LVAL" and "immediate".(3) In this period camera executes trigger immediately (no delay)(2)Fig. 15.
