    Yes they are, mainly DMG machines (Maho, Dekel , Gildemeister). Now seems that Mikron is taking part of the market but DMG leads the market (as far as i know)

    @mouldcugir: I am trying the same with a MAHO MH400 / Philips 432 control and the CGA Converter ACV-011.
    But unfortunately I am only getting a "Blackscreen". What are the positions of the 4 DIP-switches on the ACV-011?
    Would be great if somebody could help!!

    Default monitor dead MH800C

    Did you solve the problem on your MH400? I bought the converter GBS-8220, it's next gen of the ACV-011 converter, but I didn't get any picture. I ordered the old version now, since it should work. If you have any information what you did to get an LCD monitor working, please let me know.

    To summarize:
    The DB9 is wired as:
    1=GND
    2=Green
    3=
    4=Vertical sync
    5=12v
    6=Horizontal Sync
    7=Red
    8=
    9=Blue

    From the Maho schematics i found the following wiring: (note: the monitor has a female DB15, the cable a male DB15)
    The DB15 is wired as:
    2=BLUE
    3=GND
    4=GREEN
    6=RED
    11=Vertical Sync
    13=Horizontal Sync

    I first tried the arcade CGA convertor Arcade Game CGA convertor board GBS-8220 from aliexpress. This did not work on the Philips 432, i think because the Horizontal and vertical sync had not separate connections.

    Now i just received the ACV-011 CGA converter, which has separate sync inputs, but still no result.
    I double-double checked the wiring, it is as above stated.

    The ACV-011 manual gives ALL SWITCHES ON for separate sync, tried this, and other switch combinations, but nothing works.

    Will wire up now from the Philips 432 controller to avoid using the DB15 connection...
    The Philips 432 has a female DB9 video connector.

    CGA is 15.7Khz horizontal sync frequency with positive vertical and horizontal sync signals.

    As long as the control output matches those parameters, a CGA or CGA compliant display will work.

    After measuring with the frequency counter i found the 15.7 Khz. I am colourblind for red green and had the green and Horozontal sync mixed up...
    Display is working now with the ACV-011, dipswitches all on.

    Thanks.
