User's Manual

Active Mode
Active mode screens guides the user through the balance of the transaction proses related to the event that triggered
this mode. The MSCM continuously manages the power and operation of the connected and configured peripherals.
Connection to the backend systems via the GSM / CDMA interface may occur during this mode for card payment
authorisations or alarm conditions. Active mode reverts to idle mode on completion of the transaction.
Diagnostic Mode
Access to this mode is via a diagnostic button on the back of the MSCM or the by the insertion of a valid diagnostic card.
Navigation through the diagnostic menus is done via the four primary keypad buttons (+, -, cancel and OK) or via the
equivalent four buttons on the back of the MSCM. Access to the diagnostic mode should be cancelled explicitly. A no-
activity time out will also cancel this mode.
Cash Collection Mode
Cash collection is initiated by the insertion of a valid cash-collector’s card and exchanging the coin box and or bank note
stacker. This event is used to reset associated counters, establish a reconciliation point which is communicated to the
back-end and to print a cash collection receipt if configured to do so. The receipt accompanies the coin box /canister
and or bank note stacker as an additional security measure if required by the customer.
Primary and I/O Processors
Two linked Ti MSP430F5438 mixed signal microcontrollers form the Primary and I/O Processor pair.
The Primary Processor (U43) manages the functions normally associated with single space parking meters such as the
user interface, coin validator, card reader, server (back-end system) access, wireless vehicle detection, wireless coin
container communications, Host ID (RFID) detection and motion sensing.
The I/O Processor (U20) manages the additional functions associated with multi space parking meters such as the
receipt printer, bank note acceptor different keypad configurations, coin handling units, expiry indicators, down light
controllers and various cabinet sensors.

3-AXIS DIGITAL COMPASS
A Honeywell HMC5983 (U57) is a temperature compensated three-axis integrated circuit magnetometer and is used to
sense the MSCM’s orientation and motion.

I/O Sensors (H4)
This 14-way bus provides I2C comms, Connection for an external 25VP-P Piezo buzzer, and eight discrete switches to
GND. The switches are used to sense the status of various doors and locks in the cabinet. To conserve power these lines
