    When I use single green projectors, the brightness control doesn't work. The blanking is work.
    In the projector diode driver is analog, but the Ilda signals arrive the Ilda Balanking / intensity port to diode driver analog input.

    I tested the dioda driver and I connect the single green ilda port, the brightness controll is worked perfectly.
    Then I measured the FB intensity / Blankink output port voltage. The voltage is 0 or +4.8V. Not regulated. (why?)

    When I use the FB3's with RGB projector, the all fuction work perfectly.

    Maybe, is the FB3 not know the Intensity / Blanking port? Or the Ilda intensity / Blanking port never add regulate voltage?

    What is the normal function?

    Thank you,

    The first thing I think of is that the software is set to ttl. Did you already check that out?

    No, my Beyond / scanner setting is analog. Off course I try the settings single green mode and rgb mode also.

    I checked 3pcs FB3 Blanking / Intensity ports.
    With QS voltage is 0 or 4.5V, no regulated.
    With Beyond voltage is 0 or 4.8V, no regulated.

    Scanner setting is was / Single color / Analog modulation.

    When I checked the FB3 Blanking / Intensity ports voltage, I used the softwares Master brightness controll and FX brightnes effect.

    The question is:
    Is available the brightness control or not when connect to ILDA Intensity / Blanking pinout?

    I received a good response on the Facebook Pangolin forum.

    "" The intensity is TTL and usually used to drive a safety shutter these days.
    If you set the software to single colour laser then it shouldn’t matter which colour channel you use, all will be affected by the cue.""


    Thank you Bob, and I close this Thread.
