1INTRODUCTION
This manual describes the operation of the SMART Hopper programmed with version
SH00026 firmware or later. As a result of Innovative Technology Ltd continuous
improvement policies, some functions mentioned in this manual may be changed. New
functions may also be added.
This document is intended for those who will
Install the SMART Hopper
Maintain the SMART Hopper
Although information is included in this document that will allow a degree of fault diagnosis
and repair, it is recommended that for all but simple repairs, the unit must be returned to an
approved service centre for repair.
CAUTIONS
Never exceed the recommended environmental and electrical limits.
Do not attempt to lubricate the mechanisms as this may affect the coin transport.
Always ensure power is removed from the hopper before carrying out any work.
WARNINGS
Only suitably trained personnel should carry out any work on this equipment in
accordance with all current local, national and international health and safety
regulations.
Always ensure the bottom cash box exit is clear to allow coins to exit the SMART
Hopper. Failure to do so can result in permanent damage to the internal
mechanisms
We recommend that you study this manual as there are many new features permitting new
uses and more secure applications. If you do not understand any part of this manual please
contact your local office for assistance.In this way we may continue to improve our
product.
Innovative Technology Ltd has a policy of continual product improvement. As a result the
products supplied may vary from the specification described here.

3GENERAL DESCRIPTION
The Innovative Technology SMART Hopper sets new standards for coin handling technology.

Other Features Include: -
Floating function–When the hopper receives the command to float to a
required level, coins are sent to the cash box until the requested float level
remains in the hopper
No need for additional sorters, hoppers or tubing –all coins validated by the
coin mechanism enter the hopper. The hopper will then send coins not required
for future payments to the cash box.
Built in security –modulated coin exit sensor; 128 bit AES Encrypted SSP
communications (eSSP); locking option.
The SMART Hopper can be used to control a coin acceptor making machine
wiring and software implementation simpler. There is no need to have a
separate ccTalk bus to control the coin acceptor. Only 1 SSP bus is required, the
hopper then communicates with the coin acceptor using a ccTalk connection.

4INSTALLATION
4.1 HOPPER INSTALLATION
1. Secure the mounting plate using the 6 fixing holes shown in Appendix B –
Dimension Drawing.
2. Connect the cable from the host machine to the connector on the rear of the
mounting plate. See Chapter 5.2.2 - Interface Connector for connection details.
3. Slide the hopper onto the base plate; ensuring the hopper is fully pushed into
position.
4. Apply power to the machine.
NOTES ON SAFETY
Do not put a hand into the hopper while power is applied.
It is possible for a static charge to be transferred onto the coins during
normal operation. The coins should be discharged to earth before they are
accessible to the user.
The base plate should always be connected to earth during operation to
avoid a build-up of static electricity inside the unit.
WARNING
Always ensure the bottom cash box exit on the underside of the SMART
Hopper is clear to allow coins to exit. Failure to do so can result in
permanent damage to the internal mechanisms

4.2 LOCK INSTALLATION
The SMART Hopper has the option to add a lock that prevents the hopper being removed from the mounting plate. The hopper uses a standard lock PA650 which
includes all the parts shown with an asterisk *. The lock cam can be ordered from Innovative Technology, part MC211.
Remove the two screws from the base of the unit, and unclip the Lock
Bracket as shown
Assemble the lock in the order shown paying close attention to the orientation
of parts
Unclip the Lock Blank from the Lock Bracket
Place the Lock Bracket over the Lock Body and secure with the Retaining Nut
Place the Lock Plate and Lock Cam over the shaft of the Lock Body and secure
with the Lock End Nut
Fit the assembly to the base of the hopper unit and secure with the two screws.
(The Lock Blank is no longer required)

5MACHINE INTERFACES
5.1 STATUS LEDS
The SMART Hopper has 2 status LED’s located on the front panel, one Green, one Red. The
green status LED indicates system health, while the red status LED is used to indicate
system problems; these are described below in Table 7 - LED Status Codes. The red LED will
flash a number of times according to the status, pause and then flash the code again.

5.3 COMMUNICATION PROTOCOLS
5.3.1 ENCRYPTED SSP (eSSP)
eSSP is a secure serial interface specifically designed to address the problems experienced
by cash systems in gaming machines. Problems such as acceptor swapping,
reprogramming acceptors and line tapping are all addressed.
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.
A Diffie-Hellman key exchange is used to allow the host machine and SMART hopper to
jointly establish a shared secret key over an insecure communications channel. The
encryption algorithm used is AES with a 128-bit key; this provides a very high level of
security.
IMPORTANT: All transactions with the SMART Hopper must be encrypted to prevent
dispense commands being recorded and replayed by an external device.
For detailed information and full protocol specification please refer to SSP Interface
Specification (ITL Drawing GA138), this is available from the ITL website www.innovative-
technology.co.uk.
For a list of SMART Hopper specific commands see Appendix C –ESSP Commands.
Examples of communications between host machine and SMART Hopper are shown in
Appendix D –Example ESSP Communications

6PROGRAMMING THE SMART HOPPER
The SMART Hopper must be programmed with a dataset to recognise different currencies
and denominations of coins. The Hopper will leave the factory pre-programmed with the
required dataset, however it may be necessary to re-program the hopper as new coins are
introduced or updates are made to the dataset. To program the SMART hopper a PC must
be used running the ITL SMART PIPS software version 1.4.5 or later.
Connect the hopper to the PC via a DA2 with cable assemblies CN385 and CN389 as
shown in Figure 3 - Connecting the SMART hopper to a PC
Figure 3 - Connecting the SMART hopper to a PC
Using SMART PIPS software, select Utilities –Run PIPS System. Or press the Start-up
Button.
WARNING
Always ensure that the
bottom cash box exit is clear
to allow coins to exit the
hopper

Maintenance
The SMART Hopper has been designed to minimise any performance variation over time.
Much of this is achieved by careful hardware and software design.
6.1 CLEARING A JAM
On the unlikely event of a coin jamming within the SMART Hopper, follow the steps below
1. Power off the hopper
2. Remove the hopper from the mounting plate
3. Empty all coins from the coin bowl
4. Clear the jammed coin from the disk
5. Re-fit the hopper to the mounting plate
6. Re-fill the hopper
7. Apply power
8. Test operation
