EMI measures:

• Added ground wires to prevent interference between signals;

• EMC components added to AT5 PCB board to ensure reliability of the system.

Secured interfaces:

• USB;

• NFC.

Distance information:

• Distance sensor pulse input

• Low voltage : max 0,8 V

• High Voltage : min 3 V

• Trigger : Low-High transition

1.2 Essential characteristics

Legally relevant functions:

• Calculation modes S or D, incorporated in the tariff structure;

• Operating positions "For Hire", "Hired", "Stopped";

• Totaliser data;

• Long term data storage;

• Checking plausibility of distance measurement signal:

• Speed > 200 km/h;

• Interruption of distance sensor signal line.

Test connector:

1.3 Essential shapes

Markings:

• fulfil the requirements stated in the legislation;

• the descriptive markings plate is fixed to the front of the taximeter.

1.4 Conditional parts

The taximeter may be equipped with the following peripheral device(s):

1.5 Non-essential parts

The taximeter may be connected to non-essential devices, for example but not limited to mobile data terminal, card readers, seat sensors and roof lights, provided that:

• They do not present primary data not presented by the taximeter;

• They do not lead to an instrument having other essential characteristics than those fixed by this type-examination document.

2 Seals

To secure components that may not be dismantled or adjusted by the user, the taximeter has to be secured in a suitable manner on the locations indicated in the drawing:

A NFC card is needed for the following functions:

• Manual tariff change;

• Changing k-constant;

• Change time.

When a NFC card is used, the event logger and checksums record the changes.

Sealing and separate securing of parameters:

• The general settings (including settings depending on national regulations) are protected by identifier and checksum;

• The tariffs are protected by identifier (date) and checksum and secured by NFC card;

• The adjustments to the taximeter are protected by mechanical seal and event counter;

• Depending on national regulations the identifiers and/or checksums and/or event counter value(s) are marked on the prescribed provision.

3 Conditions for conformity assessment

The marks, facilities for the marks and the inscriptions on the taximeter fulfil the requirements of OIML R 21.
