    Trying to connect Huvitz AutoBlocker CAB4000 with data transmission OMA protocol

    Hi, I'm trying to connect my tracer+edger to transmit shapes to my lens provider; I get to the point to have data received on my PC but trasmission never result in a shape, althought the app say the for is correctly received and trasnmitted, here is some sample data:

    Code:
    DO=B
    ANS=TRC
    JOB=METAL:0002869
    DATA_TYPE=19
    FTYPE=3
    P_FPD=6916
    LAYOUT=17.928;0;5.000;5.000;25.000;0;0
    P_R_CIR=146301
    P_R_3D_ANGLE=0
    P_R_FC=5684
    R_LOPT=30.200;0.000
    R_EOPT=1;0;1;0;0;1;1;1.200;0.000;0.400;0.600
    P_L_CIR=146272
    P_L_3D_ANGLE=0
    P_L_FC=5630
    L_LOPT=30.200;0.000
    L_EOPT=1;0;1;0;0;1;1;1.200;0.000;0.400;0.600
    TRCFMT=5;1440;U;R;F
    TRCFMT=5;1440;U;R;F
    CRC=26173

    DO record indicates that both lenses will be supplied and the record apply to both
    ANS record indicates it's an answer packet from the TRC tracer
    JOB record is the job number in this case they are using a colon in the job id with METAL I assume to mean a metal frame as the first data point and the 0002869 as the job number this is not conventional.

    The Standard allows for device manufacturers to create new records for additional functionality and possibly even submission for approval in the new standard by indicated the an experimental record, which should start with an "_", in the case the underscore is in the middle of the label so again this is non-conventional.

    DATA_TYPE ?
    FTYPE record indicates I am assuming this is an equivalent of FTYP notice the E is missing, this again is unconventional to add letters to the record label but I assume they mean the same, FTYP indicates the frame type a 3 means the frame is a rimless frame.
    P_FPD (unconventional) I am assuming this is the far pupillary distance which should have used the IPD record
    LAYOUT (unconventional) it looks like the layout record is combining multiple records into a compact record, could be horizontal decentration, vertical decentration, height, width, etc.


    I could go on and on, anyway the records there mostly make sense, you may need to run a separate conversion program to take the huvitz trace files an convert them to proper OMA files. I had the pleasure of doing this to the Santinelli trace files which were 99% OMA compliant with some artifacts left over from experimental records that had been approved.

    A side not the TRCFMT=5;1440;U;R;F, the 5 is reserved for future formats, as far as I know a more compact format that could possibly take the 5 format doesn't exist yet except maybe by the huvitz, then the U later indicates that the trace radii supplied is unequal meaning the 1440 trace points around the lens are not equally taken so a corresponding angle record must be there to be able to do anything with this trace.

    I am assuming the EOPT records are probably the radius data in their particular format.

    If you have more samples like a lot more I used a statistical analysis program to identify the records and correlate them to a few know records or parameters from traces which helped decipher the santinelli version.

    Which is the program i can use to convert Huvitz trace file to Oma?

    Sorry I should have been clear you need to create the program for conversion. It looks like the full paste in you posted has everything it needs and understandable as well. I'll take a better look tonight when I get home. The format definitely needs to be converted from a 5, but there's no information about what a 5 format is, it looks like a simple diff, the first radius is an absolute and the following are diffs. I'll see if I can create an image for you to take a look at and confirm the shape if it's correct then you now know how to decode and encode a huvitz format 5.

    Something you could do to make conversion easier is to then set the edger to a specific format, if I remember correctly huvitz edgers allow you to set the maximum format, for simplicity I would say set it to format 1 which will take longer to transmit but give you exact radius and angles without having to unpack the numbers.

    Hi Make Optics, in my Autoblocker i have the following Data Format: ASCII Absolute, Binary Absolute, Binary Differential, Packed Binary and Data Points: 1440, 1200, 1000, 800, 500. Which is the correct combination? Thank you for your help.
