CPI MARS MEI VN 2502 U3 bill validator that has the latest firmware update and accepts all the new currency ($1,$2 and $5). This validator has the VFM style bezel. The option switches are as follows: 1-way, 2-way and 4- way acceptance.  High acceptance/ high security. Next there are option switches for accept/ reject $1, $2 and  $5 bills. Lastly, switch 7 and 8 are for pulse settings (short, long, credit line and serial). This unit has the 6-pin mdb 24v connection as shown in pics. This will work in a wide range of applications that utilize the 6 pin 24v mdb connection. For other validators check my other listings.  I have worked in the vending industry for 20+ years and Mars bill acceptors/validators are the most durable, dependable and most easily maintained validators on the market. If you find that your old coinco validators are constantly jamming and causing lost time on service calls and angry customers, try out a Mars validator and you will want to update your whole fleet with them! I ship out fast and it ships priority so you will get it quickly. Unit has been thoroughly tested and comes with the harness shown in the pictures. Thanks!!!
