2、162-2:1999 This British Standard, having been prepared under the directionof the Electrotechnical Sector Committee, was publishedunder the authority ofthe Standards Committee andcomes into effect on 15 February1999 BSI 06-1999 ISBN 0 580 308448 National foreword This British Standard is the English
3、language version of EN61162-2:1998. It is identical with IEC61162-2:1998. The UK participation in its preparation was entrusted to Technical Committee EPL/80, Marine naviagation and radiocommunication equipment and systems, which has the responsibility to: aid enquirers to understand the text; prese
4、nt to the responsible international/European committee any enquiries on the interpretation, or proposals for change, and keep the UK interests informed; monitor related international and European developments and promulgate them in the UK. A list of organizations represented on this committee can be
5、 obtained on request to its secretary. From1 January1997, all IEC publications have the number60000added to the old number. For instance, IEC27-1 has been renumbered as IEC60027-1. For a period of time during the change over from one numbering system to the other, publications may contain identifier
6、s from both systems. Cross-references Attention is drawn to the fact that CEN and CENELEC Standards normally include an annex which lists normative references to international publications with their corresponding European publications. The British Standards which implement these international or Eu
7、ropean publications may be found in the BSI Standards Catalogue under the section entitled “International Standards Correspondence Index”, or by using the “Find” facility of the BSI Standards Electronic Catalogue. A British Standard does not purport to include all the necessary provisions of a contr
8、act. Users of British Standards are responsible for their correct application. Compliance with a British Standard does not of itself confer immunity from legal obligations.

25、when interconnected via an appropriate interface. This standard is intended to support one-way serial data transmission from a single talker to one or more listeners. This data is in printable ASCII form and may include any information as specified by approved sentences or information coded accordin
26、g to the rules for proprietary sentences. Typical messages may be from11to a maximum of79characters in length and generally require repetition rates up to once per20ms. The electrical definitions in this standard are intended to accommodate higher data rates than are specified in IEC61162-1. Since t
27、here is no provision for guaranteed delivery of messages and only limited error-checking capability, this standard should be used with caution in all safety applications. Annex A contains a list of relevant IMO resolutions and ITU recommendations to which this standard applies. 1.2 Normative referen
28、ces The following normative documents contain provisions which, through reference in this text, constitute provisions of this part of IEC61162. At the time of publication, the editions indicated were valid. All normative documents are subject to revision, and parties to agreements based on this part

Where there is a conflict, terms shall be interpreted, wherever possible, in accordance with the references in1.2. For the purposes of this part of IEC61162, the following definitions apply. talker any device w

35、ification of the A, B and common (C) signal lines; b) the output drive capability as a talker; c) a list of approved sentences, noting unused fields, proprietary sentences transmitted as a talker, data latency and transmission interval for each sentence; d) the load requirements as a listener; e) a
36、list of sentences and associated data fields that are required by, or are acceptable to, a listener; f) the current software and hardware revision if this is relevant to the interface; g) an electrical description or schematic of the listener/talker input/output circuits citing actual components and
37、 devices used, including connector type and part number; h) the version number and date of update of the standard for which compliance is sought. 2.2 Additional information As latency, filtering, error handling and data transmission interval can have a serious influence on the performance of a syste
38、m, the manufacturer shall give careful consideration to these aspects. Documentation should include such data where applicable. 3 Hardware specification One talker and multiple listeners may be connected in parallel over interconnecting wires. Because of EMC requirements shielded cables are recommen
39、ded. The number of listeners depends on the output capability, the input drive requirements of the connected devices, and on the use of termination resistors. 3.1 Interconnecting wires Interconnection between devices may be by means of a shielded two-conductor twisted-pair wire (A, B) plus any means
40、 to secure common signal ground potential (C) for transmitting and receiving devices. For this purpose, a third wire additional to the twisted pair or the inner shield of double-shielded cable with insulated shields may be used. 3.2 Conductor definitions The conductors referred to in this standard a
41、re the signal lines A, B, C (common) and shield. 3.3 Electrical connection/shield requirements All signal and common line connections A, B and C are connected in parallel. With single-shielded cables and a separate wire as common line C (signal ground), the shield shall be connected to the talker ch
42、assis and shall not be connected to any listener. However, the shield shall be continuous (unbroken) between all listeners see Figure 1 and Figure 2a). With double-shielded cables and the inner shield used as common line C (signal ground), the outer shield shall be connected to the talker chassis an
43、d shall not be connected to any listener. However, the outer shield shall be continuous (unbroken) between all listeners see Figure 1 and Figure 2b). With double-shielded cables and a separate wire as common line C (signal ground), the inner shield shall be connected to the talker chassis and shall
44、not be connected to any listener. However, the inner shield shall be continuous (unbroken) between all listeners. The outer shield may be connected to the chassis on either side if required see Figure 1 and Figure 2b). The cabling shall be designed in a way that stubs are avoided or kept as short as
45、 possible. If long cables are necessary, termination at the end of the line according to ITU-T V.11 shall be considered. 3.4 Connector No standard connector is specified. Wherever possible readily available commercial connectors shall be used. Manufacturers shall provide means for user identificatio
46、n of the connections used. 3.5 Electrical signal characteristics This subclause describes the electrical characteristics of transmitters and receivers.EN61162-2:1998 BSI 06-1999 5 3.5.1 Signal state definitions The idle, marking, logical1, OFF or stop bit state is defined by a negative voltage on li
47、ne A with respect to line B, as in IEC61162-1. The active, spacing, logical0, ON or start bit state is defined by a positive voltage on line A with respect to line B, as in IEC61162-1. 3.5.2 Talker drive circuits No provision is made for more than a single talker to be connected to the bus. The driv
48、e circuit shall meet, as a minimum, the requirements of ITU-T V.11. Improved and compatible driver circuits (e.g.EIA-485) used in a compliant way are allowed. 3.5.3 Listener receive circuits Multiple listeners may be connected to a single talker. The listeners receive circuit shall comply with ITU-T
49、 V.11. Optional termination resistors for the line shall be provided. The input terminals A, B and C shall be electrically isolated from the remaining electronics of the listening device. Reference is made to3.5.4 and a sample circuit shown in Figure 1 of this standard. 3.5.4 Electrical isolation Within a listener there shall be no direct electrical connection between the signal lines A and B, the signal ground C or the shield to ships mains ground or power line. This isolation shall be in accordance with IEC60945. 3.
