    Hi everybody

    I would like to find the datasheet for al old FG209M2 fluorecent display. I retrieved from al old pHmeter, and it looks OK. The getter is still black, so it seems that it has not lost the vacuum.

    I searched for a while on Google, but I found nothing about the datasheet. I couldn't access (by some unkonwn reason) the page at radiomuseum.org, maybe there is something there.

    Can anybody help me to get the datasheet of this device?

    Thanks in advance.

    seems to be a difficult one

    I even signed up to 2 places promising datasheets only to find they don't :(

    Ok dave, understood.
    I will continue my search for him.
    Can someone confirm that this is:
    Noritake Itron FG209M2 8"x1" vfd?

    Hi Martin

    I found that one too. I have the UDN6118A drivers for the display and I also have the datasheet for the drivers, but I have not been able to find the datasheet for the display.

    As it seems very hard to get the datasheet, I thought that I could find the info in the schematic of the device which used this display......and I founded. In our library we have the schematic of the Radiometer PHM83 pHmeter. And here is the info that I found:

    Pins 1, 18 Heater (6,3V AC)

    Pin - Segment
    14 - h
    13 - g
    12 - f
    15 - e
    17 - d
    16 - c
    11 - b
    10 - a
    7 - n
    6 - m
    5 - l
    9 - k
    4 - j
    8 - i
    2 - comma
    3 - decimal point

    Pin - Digit
    19 - 1
    20 - 2
    21 - 3
    22 - 4
    23 - 5
    24 - 6
    25 - 7
    26 - 8
    27 - 9
    28 - 10
    29 - 11
    30 - 12
    31 - 13
    32 - 14
    33 - 15
    34 - 16
    35 - 17
    36 - 18
    37 - 19
    38 - 20

    I will take some pictures of the schematic to be posted here. It is very big for scanning.
