fhamann Posted July 17, 2018 Share Posted July 17, 2018 Hi all, I recently acquired a USI 3160 snack machine with the optical iVend drop sensor. Everything seems to work except the iVend drop sensor function. The diagnose error code shows VMC 8 which indicates "eyes on the activated optical sensor are blocked." I see no blockage. I have set the optical to "on" per the manual. When a vend is made, the motor turns and reports a successful vend even with no product in the coil, meaning the drop sensor is not working. The red LED indicator on the iVend board is not lit (the manual says that it should be lit). I set the "range of optical mode" for all rows A-G. The vending machine acts like there is no drop sensor installed. What do you think is causing this problem? Also, the firmware is 67185-5. I would like to install a USA Tech card reader. The USA Technologies ePort Compatibility Chart says I need firmware 67185-8 or higher. How do I upgrade the firmware? Do I buy a firmware chip? From whom? Or do I send the entire control board to some place for the firmware upgrade? Who or where can do this firmware upgrade? Thanks, Frank Orange, CA Link to comment Share on other sites More sharing options...
AZVendor Posted July 18, 2018 Share Posted July 18, 2018 Error 8 is a card reader error, not an I-vend error. You probably need to turn on your I-vend feature in the programming. Page 12 of this manual will show you the programming matrix: http://vendnetusa.com/wfdata/files/4211415c.pdf. This manual will also tell you how to program this machine since both manuals are for SM6 machines: http://vendnetusa.com/wfdata/files/4211051b.pdf. You may find one easier to understand than the other. You will need an Eprom chip from Vendnet to upgrade your firmware. Link to comment Share on other sites More sharing options...
