I loaded my project on a Panelview we had in stock, and swapped it with the PvP in question (without shutting the machine down). Took that one to my office and flashed it up as high as the hardware would let me (5.09), it is a ~12 year old old pvp1000. Worked like a charm. I really hoped there was a way to make it work without having to flash it up. We have several panelviews running frn < 5 and some of them I cannot pull with the equipment running due to our electrical safety policy.
