4.10 SEC Meter
The “Starpoint Electronic Counter” is an electronic counter designed to replace all traditional
mechanical meters in a gaming machine. It is located in the refill meter position near the coin
entry bezel.
The main features are:
The “SEC” replaces up to 31 mechanical meters with individual counters stored electronically
in EEPROM within the unit.
It is fitted with a 7 digit Liquid Crystal Display to show the contents of these counters.
The host machine controls the display of the various meters and text to explain which meter
is being shown.
The electronic meter uses the existing mechanical “Meters” port on the MPU5 to interface to
the machine.
The SEC interfaces to the host machine using secure protocol to reduce the risk of
tampering.
The MPU6 board which has the ability to sense whether the meters are correctly connected.
This facility may be programmed to give an alarm condition and prevent operation of the
machine if, for example if the meter connector is disconnected.
4.11 Dataport interface
To enable the MPU6 to be easily and securely interfaced to a Datapak, which may be
specified to back up the electronic metering and provide a downloadable machine event
store, an industry standard Dataport is fitted. This comprises a 25-way D-type socket,
identified on the MPU6 cover, for serial transmit/receive signals and with +12V and -12V
power supplies, as shown in Fig 22.
The Dataport is also compatible with the RS232 standard used as a serial interface
throughout the electronics industry; this provides an easy means of connecting peripheral
devices such as printers, terminals and modems.
