Smart Coin System User Manual
Interface communication from the SMART Hopper unit to the host machine can
communicate via SSP or CCT.
The SSP pin numbering of the socket is shown below, as well as an overview of the
socket connections:
The USB connector is a standard Type B USB socket. The USB socket can be used for
programming the SMART Hopper unit and also bench testing – a USB 2.0 compliant
Type 'A' to 'B' lead can be used to do this. USB cables should be electrically shielded
and less than 5 metres long. Please note: Direct USB should NOT be used for Host
communications. If USB is required than our IF17 (TTL to USB) should be used.
