I recently purchased the USB/Serial adapter for the AK5 coin machine... and to be honest, I'm not impressed with the quality of the device.
There are three very small wires between the USB adapter and the plugin into the Ak5 coin acceptor... and two of them have broken at the point where they attach to the coin acceptor. This is very annoying. I did not excessively manipulate these wires to cause them to break.
Also, the USB adapter is contained inside a very big plastic case, and does not fit into a USB slot if there are any other USB devices beside it. My computer has four USB ports all close together.. and I can't plug anything else in if I plug in this USB/Serial adapter.
The "solution" is to somehow fix the adapter to the AK5 coin accepter unit itself, and then use a USB extension cable to plug it into the computer.
The problem is that there is no way to easily attach the USB/Serial device to the coin acceptor.

(There are no screw mouting points, and if I use Zip straps, then the coin acceptor doesn't work since the straps interfere with operation.)
I ended up using double sided tape.. which I think is not really very good solution... so I am writing to let you know that this usb/serial device needs a bit of "work" to make it usable without requiring your customer to be a handy-man.
Thanks!
