Sintron] Multi Coin Acceptor Selector CH-926 and USB Timer Control Board for Vending Machine, accept 6 kinds of coins

It's not bad value for money, assuming that it works – something I have not yet been able to establish, due to the woefully inadequate instructions. The face plate seems rather flimsy, but should be fine in a safe environment. It is described as accepting coins up to 32mm diameter: this includes the Swiss 5Fr coin which is just below the limit, but this cannot be removed if rejected, for its diameter prevents it passing through the reject slot; it may be possible to remove the obstruction, but I haven't tried this as it would involve cutting away a bar. The £2 coin is small enough to avoid this problem.The instructions for the coin mechanism explain in detail how to teach it to accept different coins, which seems straightforward enough, but there is little explanation of how it should be connected electrically, and there is a 4-pin Molex connector underneath whose purpose is a mystery – it isn't mentioned at all.The display panel looks well made, but again is let down by indifferent instructions which detail how to programme it but with smudgy illustrations and no suggestion of how it might be connected to the coin mechanism or actually used to control anything, other than a vague reference to switching USB.The bundle would probably rate four stars with better instructions.
