25、hout personnel being present in the same room as the transmitter. Normally, supervisory equipment is installed which continuously monitors and sometimes controls the operation of the transmitters. The supervisory equipment may range from a simple unit which merely extends indications and controls in
26、to an adjacent room, to a highly sophisticated system enabling a large number of transmitters to be controlled from a common point. The majority of existing transmitters employ wired interconnections; however, the advent of microprocessors and software techniques will require different interconnecti
27、on methods, for example, by means of optical fibres. It therefore seems appropriate to divide IEC 60864 into two parts, part 1 dealing with dedicated interconnections and part 2 dealing with data bus type interconnections.

28、997 STANDARDIZATION OF INTERCONNECTIONS BETWEEN BROADCASTING TRANSMITTERS OR TRANSMITTER SYSTEMS AND SUPERVISORY EQUIPMENT - Part 2: Interface standards for systems using data bus type interconnections 1 Scope This part of IEC 60864 is applicable to all classes of transmitters for sound and televisi
29、on broadcasting. This standard may not, however, be appropriate for low power equipment, for simple transmitting 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 tr
30、ansmitters, for example intruder alarms, mast lighting, etc., are excluded from this standard. This part 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 d
31、etails the interconnections and facilities to be provided with a view to achieving compatibility between 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
32、provisions of this part of IEC 60864. 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 of IEC 60864 are encouraged to investigate the possibility of applying the most recent editions of the no
