could somebody please help me fix this ongoing problem. a friend manages a bar with UNIWELL tx-850's(POS machines), purchased new 2 yrs ago they recently started to freeze up. there is no one particular machine they have all done it at one stage. there is approx 10 units and 2 printers(in the kitchen) i ran a tempary cable around the bars to get a shorter length between units-this failed. every so called expert who has looked at it has walked away from it including the company that sells them. it currently is running on a daisy chain and i have been told an ethernet system would be better, but it comes at a price and the rep couldn't guarantee it as a fix. i am still no closer to a solution as i can't rule out hardware/software or cabling
please help
many thanks
