2 SERIAL COMPACT HOPPER
2.1 Introduction
The Serial Compact Hopper Mk2 or SCH2 is a serially controlled Compact Hopper
manufactured by Money Controls. The serial interface is ccTalk, firmly established as a leading,
low-speed device control protocol in the money-transaction industry. A key feature of ccTalk is
its optimal balance between simplicity and security.
2.2 Safety Note
To meet the requirements for EN 60950 the equipment must be installed according to the
following requirements:-
The equipment must be protected by a 3A fuse.
The equipment must be supplied from a SELV limited power source.
The equipment must be installed in an enclosure but positioned so that it is
external to any fire enclosure area within the main enclosure.
2.2.1 INSTALLATION AND REMOVAL
Warning: Ensure that the power has been disconnected from the Hopper before
removal or servicing.
2.2.2 HAZARDOUS MOVING PARTS
Warning: There are hazardous moving parts, keep fingers and other body parts away.
Consideration to this hazard must be assessed in the end use application.
2.2.3 HEALTH AND SAFETY
Warning: Due to the potential respiratory hazards, it is highly recommended that a
facemask be worn to prevent the inhalation of dust particles dislodged during the
maintenance or cleaning process or the clearing of jammed coins.
2.3 Mechanical Description
Each disc contains a number of holes in which the coins are held. The disc is driven via a gear
train, by the motor. As the disc rotates, the coin at the bottom of one of the stacks will make
contact with the ejector fingers. The fingers will move back and, at the same time, the coin will
start to move outwards to the exit slot.
Once the coin reaches the exit slot, the spring loaded ejector fingers will be able to return to
their original position and, in doing so, will push the coin out of the hopper.
An optical coin detector is created by infrared transmitters and photo detectors situated on the
PCB. The infrared light beam is routed across the exit slot via a light guide. When a coin passes
through the exit, the light beam will be broken and a coin output signal will be generated.
There are a range of discs, ejector fingers and adjuster plates available to provide optimum
performance for coins within the specified range.

2.4 Mechanical Features
2.4.1 HOPPER DIMENSIONS
The hoppers overall dimensions, mounting arrangement, coin entry and exit points are
detailed in Figure 1. Note that, when used in the side exit mode, the rear of the motor
protrudes from the rear of the casing, within the overall dimensions of the hopper envelope.
2.4.2 HOPPER WEIGHT
570 Grams
2.4.3 COIN SIZE RANGE
Hoppers can be configured to pay out coins in the diameter range 16.25-31.0mm, and within
the thickness range 1.25-3.20mm. However, each coin needs to be qualified on an individual
coin basis.
For further information on qualification of coins, please contact Money Controls Technical
Services Department.
2.4.4 COIN CAPACITY
The coin capacity of the hopper is between 200 and 700 depending on their physical size.

2.6 Installation and Removal
Warning: Ensure that the power has been disconnected from the hopper before removal.
2.6.1 DISMANTLING THE HOPPER
Gently pull out the securing clips on the back of the base.
Tilt the bowl forward until it is clear of the clips.
Slide the bowl forward until the locating lugs are clear of the slots in the base.
Remove the motor assembly from the base and disconnect the cable.
2.6.2 HOPPER ASSEMBLY
Connect the cable to the motor assembly.
Lower the motor assembly into the base, ensuring the coin exit is in the desired
position.
Locate the lugs at the front of the bowl into the slots at the front of the base.
Gently press down on the top of the bowl until the securing clips (on the base) click
into the slots on the bowl.
2.7 Why Serial?
Coin hoppers traditionally have a simple parallel interface. Common methods for paying out
coins include ‘logic motor control’ whereby a low voltage control signal can be used to turn the
motor on and off, and ‘pulse counting’ whereby a stream of pulses is used to dispense the coins
(one coin per pulse). In the ‘logic motor control’ method it is up to the host software to monitor
and count coins travelling past the payout optos.
A benefit of ‘multi-drop’ serial is the ability to connect several coin hoppers to the same wiring
harness or ‘bus’. This greatly simplifies the cabling within a machine as multiple hoppers can be
daisy-chained together rather than having to branch out from a central star point. The number of
control signals is usually much less with serial than with parallel. The only control signal in the
ccTalk protocol is a single bi-directional ‘data’ line. It is also possible with serial to connect in
other money transaction peripherals such as coin acceptors, bill validators and card readers.
The inherent ‘expandability’ of serial allows for a much better level of diagnostics and error
reporting than is available on parallel, if it is available at all. Rather than a general alarm
condition, the difference between a coin jam and a deliberate attempt to fraud the hopper can
be reported externally.
2.8 Product Features
SCH2 represents to date the most sophisticated serial coin hopper in the world.
The following features are available on SCH2…
Payout modes. The hopper defaults to multi-coin payout mode which pays up to 255
coins in a single dispense command.
Opto security. During idling (no coins being paid out), the exit optos are randomly pulsed.
If a blockage is seen while driving the opto or a short-circuit seen while not driving the

Page 10 of 45
opto then an alarm condition is generated. During pay out, if a short-circuit is seen while
not driving the opto then an alarm is generated.
Motor terminal protection. A heavy duty mechanical relay protects the motor terminals by
shorting them out during idle.
Anti-jam operation. If the hopper experiences a coin jam during a payout sequence it will
automatically reverse in order to clear the jam.
Software fuse. If an absolute maximum current threshold is exceeded (factory pre-set)
then the hopper aborts payout with an error code.
Polyswitch protection. The motor driver terminals are protected with a polyswitch for
additional overload protection.
Power fail protection. A non-volatile memory keeps track of coins paid out. If power is lost
during a payout sequence then the residual number of coins to pay can be read back
after the machine re-initialises.
Unique serial number. Each hopper is manufactured with a unique 24-bit serial number
which cannot be modified by external means.
Coin counting. Two counters record the number of coins paid out of the hopper. One is
reset-able by the user, the other is a life counter. Both are implemented in NV Memory.
Data integrity. All coin counter values in NV Memory are stored with a 8-bit checksum to
ensure data integrity.
Level plate support. There is an option to fit high or low level plates and the status of
these can be read by the host machine on serial.
Remote configuration. Motor parameters such as reversing current and payout timeout
can be changed with serial commands. No changes to electronic components are
required.
Multi-drop operation. A number of serial hoppers can be connected to the same serial
bus. Device addresses can be changed in software to any 8-bit value.
Extensive command set. Host software can implement a small or large fraction of the full
command set available depending on the application. Commands are available for
inhibiting the hopper, reading the state of the exit optos, checking the software revision
etc.
Diagnostic and error reporting. Full access to diagnostic and error codes are made
available over serial.
Code protection. The software is protected with an internal, independent, watchdog
circuit. A ‘crash’ in the software will result in a clean reset of code.

Pins 4 and 5, and pins 6 and 7, are linked internally. The provision of extra pins is to simplify
the manufacture of a multi-drop cable using thicker wire for the power leads. There can be a
‘power-in’ and a ‘power-out’ pin, and the hoppers daisy-chained.
Note: The hopper can only operate at 9600 baud.

2.12 Address Selection
A number of mating connectors on a multi-drop bus cable may each be wired uniquely to
allow operation of multiple hoppers. Since address selection is done externally, any Serial
Compact Hopper may be plugged into any position on the bus and the host machine will
know which one is paying out a particular coin.
Note: Addresses may be changed in software. Refer to the ‘Address change’ and
‘Address random’ serial commands. These values are lost at power-down or reset.

2.14 Power Fail Recovery
SCH2 contains a non-volatile memory (EEPROM) for the storage of coin counters. Therefore
if power is removed in the middle of a payout sequence then the situation can be recovered
and the residual coins paid out after power is restored. This behaviour is under control of the
host software - the hopper does not automatically dispense coins when power is re-applied.
The following counters are saved…
[Last payout : coins paid] x 1 byte
[Last payout : coins unpaid] x 1 byte
[Hopper dispense count] x 3 bytes
[Hopper life dispense count] x 3 bytes
along with their corresponding checksums.
The [Last payout: coins paid] and [Last payout: coins unpaid] bytes can be read with the
‘Request hopper status’ command.
The [Hopper dispense count] can be read with the ‘Request hopper dispense count’
command.
The [Hopper life dispense count] can be read by looking at block 3 of the NV Memory using
the ‘Read data block’ command. Refer to Appendix D for a memory map description.
After power-up initialisation, the host machine can read the [Last payout: coins unpaid] byte
to determine if there are any remaining coins to be paid out after the last session. The
decision to pay out any remaining coins is made by the host machine, not the hopper.
2.15 Power Fail in Detail
The sequence of saving the coin counters to NV Memory is triggered by the following
conditions…
Sudden loss of power with the motor running
Receipt of an ‘Emergency stop’ command
If power is suddenly lost with the motor running then the hopper will stop the motor
immediately and update the NV Memory while it has power to do so. SCH2 does not have a
‘battery back-up’ but uses a capacitor reservoir.
If power is lost after a payout sequence has completed (hopper in idle) then the
[Last payout: coins unpaid] counter is cleared, regardless of the value it was holding. This is
because it is assumed the host machine has dealt with the last payout sequence and has
taken the appropriate action. It is not desirable to flag unpaid coins during the next power-up
initialisation.
Note: This means a slow rise time or switch bounce on the power supply could
inadvertently clear the unpaid counter.
If the host machine has early notification of a power fail it can send an ‘Emergency stop’
command to the hopper. This command stops the motor dead and returns the number of
unpaid coins back to the host. This value should be stored by the host machine prior to
power being lost.

In this more complicated example, the hopper dispense count and the hopper life dispense
count end up with the correct values even though a coin was seen on the exit optos after the
motor stopped. For the host machine to find the correct value of unpaid coins it would need
to re-send the ‘Emergency stop’ command or use the ‘Request hopper status’ command
before power was lost - otherwise it would think there were 7 unpaid coins rather than 6.

Therefore if you need to know the number of remaining coins during a power fail and wish to
use the ‘Emergency stop’ command, please ensure that you have enough time to send this
command and a ‘Request hopper status’ before power is lost. This gives the best possible
accuracy. The host machine needs at least 100ms of notice before the power supply dips
below Vtrip (see Appendix B).
2.16 What happens…?
2.16.1 WHAT HAPPENS AFTER POWER UP?
The following is a guide to what happens when power is lost and re-applied.
Device Address
Defaults to the connector address
PIN Number
Retained but needs to be re-entered
Motor Variables
[current limit] = default value
[motor stop delay] = default value
[payout timeout] = default value
[maximum current measured] = ZERO
See Appendix A for default values.
Flags
Refer to the Flag Action Table within the ‘Test hopper’ command description.
Note that the ‘Power-up’ flag is set to indicate the power supply really was lost and the
hopper defaults to multi-coin payout mode. The hopper also starts inhibited and needs to be
enabled prior to coin dispensing.
Counter checksum flags are updated.
Counters
Hopper dispense count = last value
Hopper life dispense count = last value
Request hopper status
[event counter] = ZERO
[payout coins remaining] = ZERO
[last payout : coins paid] = last value
[last payout : coins unpaid] = ZERO or last value if power lost during payout
Request comms status variables
[rx timeouts] = ZERO
[rx bytes ignored] = ZERO
[rx bad checksums] = ZERO
2.16.2 WHAT HAPPENS AFTER A SOFTWARE RESET?
The following is a guide to what happens after a software reset. A software reset means
sending the ‘Reset device’ command to the hopper.

[rx bad checksums] = ZERO
2.17 Power Distribution on a Multi-Drop Bus
The multi-drop bus for Serial Compact Hoppers consists of a power, ground and serial data line.
When more than one hopper is attached to the bus, all power is transferred along a single cable
and significant ground potential rises can occur.
The following recommendations are made
Only operate one serial hopper at a time. Never initiate a second payout
sequence when one is already in progress.
Consider the use of signal conditioning on the serial data line receiver.
Perhaps a high-frequency filter and voltage comparitor input with a mid-rail
(2.5V) threshold.
Consider running separate power cables to the hoppers to alleviate the
ground potential problem.
If communication errors still occur, consider changing the topology of the
multi-drop bus network. A star network will distribute power more evenly than
a ring, tree or daisy-chain network.

2.18 Electrical Noise - Physical Measures
The ccTalk protocol is not designed for long distance transfer but for local hook-up of various
peripherals within a machine cabinet. Typical cable lengths are likely to be of the order of a few
metres.
Various measures can be taken to minimise the effects of radiated and conducted noise on the
ccTalk bus.
Use a good quality regulated power supply with mains filtering. The power
rating should be sufficient to handle a Serial Compact Hopper at maximum
surge current.
Do not run the multi-drop bus cables directly next to noisy electrical components
if at all possible. These are typically motors, relays, VDU’s, fluorescent strip
lights etc. If problems are experienced consider the use of screened cable.
Keep cable runs as short as possible.
Make sure the ccTalk data line has an appropriate load resistor at the host end
(typically 1K to 10K pull-up to +5V).
Do not place too many peripherals on the bus - consider the loading effects of
each ccTalk interface circuit. The maximum number allowed will depend on the
host transceiver circuit.
