3、reword This British Standard is the English language version of EN 60864-2:1997. It is identical with IEC 60864-2:1997. The UK participation in its preparation was entrusted to Technical Committee EPL/103, Transmitting equipment for radiocommunication, which has the responsibility to: aid enquirers

4、to understand the text; present 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 represe

5、nted on this committee can be obtained on request to its secretary. From1January1997, all IEC publications have the number 60000 added 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, publi

6、cations may contain identifiers 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 imple

7、ment these international or European 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 n

8、ecessary provisions of a contract. Users of British Standards are responsible for their correct application. Compliance with a British Standard does not of itself confer immunity from legal obligations. Summary of pages This document comprises a front cover, an inside front cover, pages i and ii, th

34、the fifth byte 304 blankEN60864-2:1997 BSI 09-1999 5 Introduction The majority of broadcasting transmitting stations are designed and constructed to operate unattended, that is without personnel being present in the same room as the transmitter. Normally, supervisory equipment is installed which con

35、tinuously monitors and sometimes controls the operation of the transmitters. The supervisory equipment may range from a simple unit which merely extends indications and controls into an adjacent room, to a highly sophisticated system enabling a large number of transmitters to be controlled from a co

36、mmon point. The majority of existing transmitters employ wired interconnections; however, the advent of microprocessors and software techniques will require different interconnection methods, for example, by means of optical fibres. It therefore seems appropriate to divide IEC60864 into two parts, p

37、art1 dealing with dedicated interconnections and part2 dealing with data bus type interconnections. 1 Scope This part of IEC 60864 is applicable to all classes of transmitters for sound and television broadcasting. This standard may not, however, be appropriate for low power equipment, for simple tr

38、ansmitting systems which consist of a small number of controlled equipment items and for certain special purpose transmitters. Any facilities and interconnections not directly associated with the transmitters, for example intruder alarms, mast lighting, etc., are excluded from this standard. This pa

39、rt of IEC 60864 deals with the interface between a transmitter (or system of transmitters) and the supervisory equipment which is intended to remotely monitor and/or control the transmitter(s). It details the interconnections and facilities to be provided with a view to achieving compatibility betwe

40、en different types and makes of transmitters and supervisory equipment. 2 Normative references The following normative documents contain provisions which, through reference in this text, constitute provisions of this part of IEC60864. At the time of publication, the editions indicated were valid. Al
