Fujinon BMD lenses Hirose 12 pinout?

[Lee2023]

Hi !

So I i'm working on finding the pinout of the Fujinon lens with a hirose female shell size 10 & 12 pins

Lens type S16x6.7BMD-D29, so BMD series

I want to confirm this or increase information level on this

1. Input - Zoom control
2. Input - Focus control
3. Output - Vref +4.50V
4. Output - 11.32V
5. Input - No idea what it's doing, another mode ?
6. Input - Iris mode, Local Manual / Camera Auto
7. Ground 0V
8. Input - Mode ??
9. Input - Mode servo on focus
10. Input - Mode ??
11. Output - Vref +2.25V
12. Ouput - Vref +6.67V

So i'm able to control zooming by control of pin 1 connecting via a protection resistor like 10k to ground or +11.32V, zoom servo is also working putting via protection resistor +11.32V on pin 9, and a pot with wiper to focus control pin 2, pot min to 0V and max to +11.32V

For now I don't really know what pin 5, 8 and 10 are doing, pin mode 8 seems to be the zoom speed, slow speed when put high via protection resistor to +11.32V

Pin 3 vref +4.50V is maybe for some logic in certain types of remote ?

Pin 11 vref ?? +2.25V maybe ''low side'' for the focus & iris pot
Pin 12 vref ?? +6.67V maybe for ''high side'' for the focus & iris pot

Since the pot is not full range when putting 0V and +11.32V on wiper min and max

Thanks !!

Ok so final information,

First I have inverted the pinout on my first post..... now remote assembled final pinout is

PINOUT FUJINON BMD

1. Input - Mode Servo Focus ON – 0V OFF / +12V ON
2. Input - Mode Servo Zoom ON – 0V OFF / +12V ON
3. Ground 0V
4. Input - Iris mode, Local Manual / Camera Auto – 0V Iris Local Manual / Float Auto
5. Input - Iris control – Pot wiper, pot between Vref +2.25 / +6.67V
6. Output - 11.32V – Supply from cam +12Vdc via fusible resistor 20 Ohms
7. Output - Vref +4.50V ?? Probably to supply some logic in some remotes
8. Input - Focus control – Pot wiper, pot between Vref +2.25 / +6.67V
9. Input - Zoom control – Pot wiper, pot between Vref +2.25 / +6.67V
10. Input - Mode ??
11. Ouput - Vref +6.67V
12. Output - Vref +2.25V

Since I don't really know what is going on in the the lens electronics, and I don't have the schematics.... I have put a 1k resistor in series with each inputs to limit current, just in case,

Hope I could help someone, feel free to add information !
