INTRODUCTION
The pattern is a taximeter designated the MR500, designed to be installed in a road vehicle
for the calculation of fares. The fares are calculated based on measurement of distance and
time, the instrument operates in single mode calculation (time or distance counting). The
instrument is powered via the vehicle battery.
The distance measuring device (transducer) is not covered by this certificate.

FUNCTIONAL DESCRIPTION
2.1
Construction
The instrument (Figure 1) is connected to a pulse generator fixed to a moving part of the
vehicle.
All electronics are enclosed in a Polycarbonate ESA case, comprising opaque
front and rear cases.
The user control and display interface comprises an LED display behind a
transparent lens, and five function keys located at the bottom of the front
panel.
The taximeter has a number of electrical connections, located at the back of
the instrument, for Power, Lamp Output, Relay Output and Communications
A screw located at the top left corner can be sealed to prevent access to the
case.
A sealable cover located at the bottom left corner of the instrument’s front face
allows access to the tariff or software card connector.
2.2
Devices
The instrument has the following devices:
Time or distance counting
Fare calculation (initial fare, fare increments, extras)
Display of rate, mode (For Hire, Hired, Stopped) and fare (actual fare and total
fare with extras)
Optional printing
Loading of tariffs and software
Real time clock
Totals (various parameters are recorded and can be recalled on demand)
Recorded journey information

Software
3.3.1
The software is designated version 2.10.00, which can be displayed via the
software menu.
3.3.2
Security
The legally relevant software is protected by a 32-bit checksum. When power is applied to
the taximeter, a separate boot loader application performs a checksum calculation on the
legally relevant software. If the checksum fails, the legally relevant software is not executed.
The legally relevant software may be changed only by means of an encrypted software card.
The card carries various data, including program data blocks and checksums, in a format
that is unique to the MR500 taximeter. The boot loader application will reject any card that
does not meet the physical, electrical, data format and encryption requirements.
Parameters affecting the measurement data can only be changed by means of an encrypted
software/tariff card.
