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.
