This Coinco MAG52R/MAG32R has been refurbished by a qualified electronic technician and comes with a 6 month labor warranty.  The MAG52R/MAG32R can replace any MDB bill acceptor/validator as well as a pulse or serial type bill acceptor using the 9 pin power cable.  This model can replace a Coinco BA30B/BA50B, MAG30B/MAG50B that is using an MDB connection or a Coinco BA32SA/BA52SA, MAG32SA/MAG52SA using the 9 pin and 18 pin connections.  It will also replace a Mars/MEI/CPi VN2502/VN2512, or VN2702/VN2712. We have updated the firmware so the unit will accept the new $5 bill; this unit can accept $1-$20 bills if the respective switch is turned on.
