MacKay Guardian™ Solo
Operation and Maintenance Guide, v. 1.5
Solo Memory
 The meter’s internal token counters increased by the number of tokens extracted from
the card, which increases as long as the card remains in the card reader device up until
the maximum time has been purchased.
Post-Purchase Solo Behavior
 If the card is left in the card reader device after the meter has reached its maximum time,
and the meter has indicated that the transaction has ended and to remove the card, the
meter will indicate to use coins only until the card has been removed.
 When the display on the meter changes to 0:01, there is one minute of purchase time
remaining. The display remains like this until the internal timer counts to zero, purchase
time is now used up and the display either goes into a predetermined overtime period
(Grace or Penalty) or shows the EXPIRED message (Violation).
6.3 Maintenance/Data Collection Using the RF Probe Interface (RFI)
The Solo electronic parking meter operates in the following manner when a device called the RF
Probe Interface (RFI) is inserted into the coin slot:
 All inserted devices will cause an interrupt to the main processor, which in turn will
activate the appropriate circuits to initiate the interrogation of the card/device that was
inserted into the card slot. If a very specific challenge and acknowledge sequence is
successful then the meter determines that it is communicating with the PDT through
the RF probe interface device.
 The meter then receives the appropriate commands from the PDT such as send audit
data, set date/time, etc.
 Once the meter has responded to the commands issued, the link is terminated and
the RFI device can be removed.
