    Default HELP! Sonima SM2804 wiring diagram ?

    Hello,

    I am currently building a green projector using Sonima SM2804 scanners.
    I didn't receive a wiring diagram and on both scanner driver pcb's for X and Y are two 3pin connectors, one is for input of X and Y signals and one is for inputting +/- 15V
    http://www.sonima.com.cn/SM2804.asp

    Both connectors aren't labeled (how convenient....)

    Now i want to know which is which, so i don't blow it up, who can help me out here ?


    Kind regards,
    Dimitri

    wow that was quick, thanks Dave, those are the same !

    I was trying to mount the scanners, reading the instructions i am a bit confused.
    I want to come in on the lower scanner, reflect the beam up and then on the higher scanner move out of the projector.

    Looking at the pictures this looks right, reading the instructions it looks wrong:
    The laser will hit the first scanner. This scanner needs to be orientated so the laser hits
    the first surface of the mirror, and is reflected downwards, onto the second scanner.


    Does the second line contradict what the first line says ?
    I go in, hit the first mirror, are reflected downwards.

    Then the second line says:
    The second scanner will need to be mounted so the first surface reflects the beam out of the scanner mounting block.

    So the first surface, that was the upper scanner, that needs to reflect the beam out ?
    But the first line says to hit the mirror, reflect downwards (probably onto the other mirror i presume).

    So now i am confused ?

    I wanted to mount the bigger mirror in the lowest position, hit that first, then UP to the smaller sized mirror and then out the projector, am i wrong ?
    I didn't fail !

    Hi Dimitri


    Connector J3= Power input (voltage input)
    PIN 1= -Vee (-15v)
    PIN 2= GND
    PIN 3= + VCC (+15v)

    Connector J1= Signal Input (ILDA Input)
    PIN 1=Control Signal (+)
    PIN 2= S GND
    PIN 3= Control Signal (+)

    Thank you all, that helped very well !
    Pictures will follow, but don't know how to fix this projector in time, everytime i want to work on it, something breaks down @ work, friends computers meltdown who need help, aaaaaaaaargh...... I will get this thing ready.

    Looking out for the weekend to continue building. Just ordered a nice IDC flatcable connector clamp plier (like a vise grip and it crimps the connector on nicely...) since i needed to press on some more. I saw the one Rob had and could get one for a good price, so things will be ok.

    Batteries are out so cannot take good pictures, blackberry only makes crappy shit, so all will be good, but not now ;-)
    I didn't fail !
