    Default T32-2 - 803 data not found

    I have 2 almost identical QT8s with T32-2. One of them has the EIA/ISO option, one of them - not.
    On the one with the EIA/ISO option it is only possible to run EIA/ISO programs, as every possible attempt to check the toolpath of a Mazatrol program results in "803 - DATA NOT FOUND" error.

    I have localized the problem to the MC116 board, as if I switch the boards between my two lathes, and the EPROM and EEPROM on it, I can run both types of programs. Unfortunately, this makes the other machine unusable, as it would return the same 803 data not found error.

    Now I can only do Mazatrol programs on one of my machines, and the other should be stuck with the G-code option only. I could probably live with that, but I do prefer to be able to program in Mazatrol also.

    The interesting part, for me, is that by switching the boards, the programs and the tool data move with them, which means that there is a lot more data stored, than what is in the two EPROM's, that I'm able to copy. Does anybody know where this data is stored, and is there a way to copy it from one board to the other? Is there a procedure for a hard reset of the board (I already did the procedure with the two DIP switches, but no luck)?

    ---

    And a second question, as I wouldn't like to open another thread - do you know a good software that can backup my Mazatrol programs on a PC by using the serial port? I tried a lot of softwares, but it seems there is some special protocol, which even the Mazview demo was able to only read when ISO programs are being transferred. No luck with extracting mazatrol ones. I'll be happy to be able to transfer the binary back and forward, I do not need to edit the mazatrol program, as I read that those kind of softwares tend to be incredibly expensive.

    Thank you for reading

    Have you tried copy the eproms from the working board and burn new eproms on the non working board?

    Maview is designed to transfer mazatrol programs, tool data, chuck data and parameters. (I use it every day)
    If you cant get it to work there is only 3 things that can go wrong.
    1, Serial port settings on PC
    2, Serial port settings on Mazak (Parameters)
    3, Cable

    What settings do you have?
    How is the cable setup?

    Yep, first thing I did, no matter what combination of EPROM/EEPROM, the 803 Data error is there, until I switch the MC116s.
    As it turns out, EIA/ISO works pretty basic, also, with the defected MC116 - I have G00, G01, haven't tried G02/G03 yet, but I hope at least they work OK. Unfortunately, no cycles (G71-76) are working - the error I get is 944 - No designated program, whenever I try to use a cycle. When I switch the MC116, both 803 and 944 errors go away and I can make fine Mazatrol and EIA/ISO programs.
    What I strongly suspect is that the cycle definitions for both EIA and Mazatrol programs are corrupted or missing on the MC116 somewhere. I'd probably need to replace the MC116, but the price of it is 1/5-th of the price that I bought the lathe for, so I will currently put that thought on hold.

    I tried with almost all the settings I found in the internet 7data bits/8 data bits, 2 stop bits, even parity/no parity etc..., and with 3 different variations of the cable, including the recommended in the Mazview help file. These days I'm going to make a final version of the cable, according to it, due to the fact that you confirm it usable, and try once again. All I managed to receive is an ISO program along with a lot of jibberish, with the PUNCH TAPE option, which I do not consider a success, because it is most probably one way communication. From what I've read I'm supposed to use the CMT I/O protocol, but no luck there.

    I heard it can be problem with some USB-Serial adapters that dont support all serial features.
    Do you have a real serial port or a USB dongle?

    I managed to run Mazview on one of the machines, as it turns out, there is something wrong with the RS232 port on the one that I was trying at first. Mazview, even the demo version, works good, I can download programs and parameters now, and if I move the MC116 board from one machine to the other, I'm capable to transfer the stored in it programs. Thanks for the affirmation that Mazview should work, benganboll!

    For the 803 and 944 errors, unfortunately, no luck. I'm pretty confident that the problem is in the MC116 board, as replacing it makes all the difference. Unfortunately, the Mitsubishi guys told me that for a small fee of 1500€ they will come to diagnose the problem. I'm now looking for assurance that the MC116-s are all the same, as I would probably be able to order an working board with some warranty for 900-1200€ from e-bay.

    The 803/944 problem is seriously driving me insane now, the only thing that I haven't tried is replacing the logic ICs from the working board to the "not working" one. Those are the small marked PLxxx from what I found by their # in the internet. I consider this test quite risky, so I'm probably not going to do that, if I don't find some assurance that it would be harmless if done correctly. There is a MC116 board "for parts" for a much more reasonable price that I consider buying, but as it is still not "cheap" in the sense of "two packs of cigarettes" I do still hesitate. Any input is greatly appreciated.
