rjh914 Posted August 24, 2018 Share Posted August 24, 2018 I upgraded the bill validator in this machine to accept $1's and 5's. It accepts $5's, but won't give $5 of credit and allow purchases. It basically just steals the money. :( I contacted the company I bought the kit from and they told me they need the software version loaded on the control board. How do I find the software version? The machine is a GF19, model 3039. The upgraded bill validator is an MEI VN 2511 U3. Thank you. Link to comment Share on other sites More sharing options...
AZVendor Posted August 24, 2018 Share Posted August 24, 2018 Power the machine off and then watch the display as it powers on again. The first thing you see is the EPROM version. Or just look at the label on the EPROM. Link to comment Share on other sites More sharing options...
rjh914 Posted August 31, 2018 Author Share Posted August 31, 2018 When I power on the machine, I hear the bill validator cycle, then It just reads "EXACT CHANGE ONLY" for a while, then switches to "ENJOY A SNACK TODAY." No software version ever flashes. Attached is a picture of the board. Which item is the EPROM? Thanks! Link to comment Share on other sites More sharing options...
AZVendor Posted August 31, 2018 Share Posted August 31, 2018 You have there a SMIII logic board that is not capable of taking $5 bills. The longest chip with the label on it is the eprom but it's not replaceable. Link to comment Share on other sites More sharing options...
