device used to read ERI data directly or indirectly from an ERT by invoking ERI transactions
NOTE 1 to entry In the case that an ERI reader exchanges the ERI protocol data units directly via a data link with an ERT it is also called an ERR. In case it communicates via one or more nodes, only the last node in this sequence is called an ERR. As a consequence, an external ERI reader can, depending on the onboard configuration for example, act for some, but not all, vehicles as an ERR.
NOTE 2 to entry See also onboard ERI reader and external ERI reader.
receives data from AEI manager, and display the data on a variable message sign to the driver
ERI reader which is part of the onboard ERI equipment
NOTE An onboard ERI reader can be, for example, a proximity coupling device (PCD) as specified in ISO/IEC 14443.
equipment fitted within or on the outside of the vehicle and used for ERI purposes
NOTE The onboard equipment includes the ERT and any communication provisions for the exchange of ERI data with an ERI reader or writer.
a device where all or part of the identity and memory can be reprogrammed many times by an external device, but not during a normal 'on the fly' read/write cycle
electronic transmitter/responder which responds to the receipt of suitable modulated or unmodulated downlink signals and transmits predetermined information according to predefined protocols at a predetermined frequency
NOTE The transmissions can be powered from energy obtained from the downlink or can be assisted by an on-board power supply. Forms the core, but not necessarily the only, function of an OBE. Within the AVI/AEI context it is fitted to AVI/AEI vehicle or equipment and its prime function is to provide the identity of the item, but can also contain additional information. In some special purposes transponders can be installed in fixed positions and read by mobile equipment.
a device which is programmed at the time of manufacture or prior to use and thereafter can only be read, with no further opportunity to change any of the data held on the device nor its core identification
electronic registration tag that can fulfill the requirements defined in ISO 24535
