I purchased a used UBA 10 on eBay recently. I have tried it on several S2000s and each time I do, it comes up with the “no disp” error. The unit does not cycle. The listing stated it was tested in working condition. When I reinstall a known working WBA, the machines work again - tested on a couple different machines with same result. If it matters, previous BV was for Canadian bills, the new one that is not working is for USD. Also tried the troubleshooting by having dips 1,2,3 and 8 down and then flipping 8 up, unit did not cycle.
Not sure if I got a bad unit or if I’m doing something wrong on my end. Any advice would be appreciated.
