I do have a problem with my Digital-Analog Converter A1S68DAV-U(H/W)-E, model code 13J809 and IB(NA)-66586-B(0104)MDOC, when I start on the "RUN" led instead to remain ON, continuously flashes, that means that there is a "write data error". So, how can I sole and fix this error? I need your help. Thank you.
