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.
Each SSP device of a particular type has a unique serial number; this number is used to
validate each device in the direction of credit transfer before transactions can take place.
Commands are currently provided for coin acceptors, note acceptors and coin hoppers. All
current features of these devices are supported.
Features:
· Serial control of Note / Coin Validators and Hoppers
· 4 wire (Tx, Rx, +V, GND) system
· RS232 (TTL) - open collector driver
· High Speed 9600 Baud Rate
· 16 bit CRC error checking
· Data Transfer Mode
Benefits:
· Proven in the field
· Simple and low cost interfacing of transaction peripherals.
· High security control of payout peripherals.
· Defence against surrogate validator fraud.
· Straight forward integration into host machines.
· Remote programming of transaction peripherals
· Open standard for universal use.
For detailed information and full protocol specification please refer to SSP Interface
Specification ITL (GA138), this is available from the ITL website www.innovative-
technology.co.uk.
To help in the software implementation of the SSP, ITL can provide DLL controls and Visual
Basic applications on request. Please contact support@innovative-technology.co.uk for
more information.
