Re: Unknown error with an equipment

    Hi Tony,
    
    The error messages you posted ought to be self-explanatory if you
    read them in order:
    
    > error:

> IDEA ImpMik:IDEA:Status: Input "#31 hv error detect" mismatch after 4 bytes
> IDEA ImpMik:IDEA:Status: got "hv error detect" where "ok" was expected
> IDEA ImpMik:IDEA:SetFilterOn: Input "#2E impossible, erro" mismatch after 1 byte
> IDEA ImpMik:IDEA:SetFilterOn: got "2E impossible, error" where "0" was expected

    Your protocol for reading the status from the device says:

> #
> # Get_Status
> #
> Get_Status {
>     out "Get status";
>     in  "#%2i ok";
>     out "ver";
>     in "EFC_for_NanoESCA V01.03 B0115";
>     out "Set mode remote";
>     in "#04 remote mode";
> }

    Thus you're telling StreamDevice that after it sends a "Get status"
    string, it will get back "#" followed by a 2-digit integer and the
    word "ok". The first two error message lines explain that instead of
    "ok" it's seeing the string "hv error detect". Have you looked at
    the instrument that it's talking to? I would guess there's a problem
    with some high voltage signal that it isn't seeing. You should
    probably fix the protocol file so it can accept error strings like
    that from the device and make them available in a stringin record
    instead of always assuming that the instrument is working and will
    never give you an error, but you might be able to resolve your
    immediate issue by fixing whatever the instrument is complaining
    about.
    
    Always fix your first error first, then look at any error messages
    you get in that state — later errors are often caused by earlier
    ones and may go away once you've fixed the first problem.
    
    HTH,
