IEC PAS 61162-102:2003 pdf download Maritime navigation and radiocommunication equipment and systems – Digital interfaces – Part 102: Single talker and multiple listeners – Extra requirements to IEC 61162-1 for the Voyage Data Recorder
Scope
The lEC 61162-1 standard includes 4 sentence formatters for handling alarm and transducerstatus data. These wer originally developed to handle the data required by navigation andradiocommunications equipment and multiple alarm systems were not envisaged.
The introduction of the Voyage Data Recorder (VDR) has necessitated the interfacing toengine, cargo and deck monitoring systems, ln particular the interface to multi-point fire alarmsystems presents problems due to the large number of sensors and the need to identifyspecific sources ofincoming messages.
The lEC 61162-102 is the specified interface to the VDR and to permit identification of data aseries of specific sentences has been developed.
Whilst the facilities included in the lEC 61162-4 series may be utilised to handle the mostcomplex svstems, these are not in genera use. and probablv unlikely on smaler vessels. TheVDR has to be applied with immediate effect to a range of vessels and there does not appearto be any alternative standard available to meet the requirement.
NOTE This document defines sentences and parameters useful for the VDR and associated systems. Thesentences and parameters extend in some cases beyond the minimum requirement for the VDR.

3Definitions
3.1
alarm
denotes a condition that has to be recognised, or acted upon immediately, e.g. depthminimum limit exceeded,anchor deep
3.2diagnosticusually denotes a failure, or warning of deterioration in a system, e.g. engine sensoimalfunction
3.3
event
is used to log a condition that has occurred and /or (track the operation of some conditionlEvents are Inormally] defined, e.g. transfer of control to the bridge
3.4
fault
is a technical problem in one of the system components that will reduce the availability, orfuture availability, of some or all functions
3.5
warningis similar to ALARM but need not be acted upon immediately
