1 Scope This document defines the cabling specifications for an onboard data transmission bus between the different parts of equipment for service operations and monitoring of the fleet. This document is applicable to equipment installed onboard buses, trolley buses and tramways only as part of a bus fleet operation. This equipment include operations aid systems, automatic passenger information systems, fare collection systems, etc. Equipment directly related to the functioning of the vehicle (e.g. driver dashboard, engine management, brake systems, door opening systems) are excluded from the scope of this document and are dealt with in other standardisation bodies. This document is not applicable to tramways operated as part of a train, subway or metro operation. Two alternative transmission buses will be accepted. This document refers to one of them (known as WORLFIP and specified in EN 50170). A second set of standards will be published for the other solution (so called CAN). The selected bus system, between the two standardised alternatives, shall be subject to an agreement between each transport operating organisation and its equipment providers. This document covers the link between equipment inside a single vehicle. Although it could be applied to multiple vehicles, this application is not explicitly covered by this document. This document is the second part of a set of standards related to the onboard transmission bus, which will define the following aspects for each allowed transmission bus: — choice of the bus and general application’s rules (EN 13149-1) — cabling specifications (EN 13149-2, this document) — message content specifications (prCEN TS 13149-3, under development) 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. EN 50170

3 Cabling specifications 3.1 General remarks The principles for the coupling of devices to the data transmission bus focus upon the longer term objectives which are to achieve the least necessary number of variants, rather than to allow for the profusion of interim and migratory solutions which may occur initially. This is especially important for public transport road vehicles, which are generally equipped in different non-correlated stages (for example, first the fare collection system, then the radio and automatic location system some months or years later, etc.) SIST EN 13149-2:2005

To avoid the disruption to the trunk continuity when a device is removed, the cable shall be joined on the trunk side of the device connector. This will allow removal of a device without causing a failure to the remaining network. SIST EN 13149-2:2005

3.10 Cable jointing The wires shall be joined to maintain the data polarity. These shall be crimped and insulated to maintain the circuit integrity. The screen continuity shall be maintained by the drain wire. The cable sheath shall be clamped to provide strain relief. See Figures 5 and 6.
