We have just bought a kiosk equipped with a MEI CF7000 change manager but are having difficulties trying to get it to work. On first startup, the change manager displays the message "Comms error" which we think is due to there being no application connected to it. When an application does connect, the message changes to "Disabled by machine". Not sure if this is normal and the documentation doesn't go into too much detail on what the messages actually mean.

The main issue is that the device won't accept any coins - it is set-up to accept UK currency, but any coins entered generate a message on the screen showing "Unknown coin". From all accounts it looks like everything is setup correctly, but there must be something that we are missing.

If anyone can shed any light or give any advice, it would be much appreciated!!
