Hi Raymond,
I've emailed you a zip containing the firmware images (U301-U304) I hope it's helpful.
I'm getting DSP and A/D error on start up now though and HV! is flashing. I'm pretty sure I've reseated the DSP board correctly but it's behaving the same as if the board isn't fitted. DSP 1 test returns -17781 error, DSP 2 -1832 errors. Any ideas ?
Kind regards,
Jon
