It is a DBV200, the latest update for that will take everything except new $5's and new $100's. The version you have, if the sticker is correct, will accept all the black/white bills plus the new colored $20's. But no other new bills. The upgrade path depends on your unit, some were eprom based, others were flash based. You will have to remove the head and look under it to see if the head has an eprom chip (socketed 32 pin chip) or an SMD mounted flash nand.
Attached firmware information for that validator.
