SECURE PROTOCOL – SSP
NOTE: Please refer to the Smiley
®
Secure Protocol (SSP) Specification (ITL Drawing
GA138) on the web site for full details of the SSP Protocol.
To use SSP mode the SSP Interface must be programmed into the validator via the
Configuration Cards (See Appendix D – Configuration Cards) or via the ITL BNV Currency
Manager Program, or by pressing and holding the Configuration Button for more than 2
seconds.
SSP is a secure serial interface specifically designed to address the problems
experienced by cash handling systems in gaming machines. Problems such as acceptor
swapping, reprogramming acceptors and line tapping are all addressed. This interface is
recommended for all new designs.
The interface uses a master slave model, the host machine is the master and the
peripherals (note acceptor, coin acceptor or coin hopper) are the slaves.
Data transfer is over a multi-drop bus using clock asynchronous serial transmission
with simple open collector drivers. The integrity of data transfers is ensured through
the use of 16 bit CRC checksums on all packets.
