Chapter 10: NMEA Module, Rev. 1.3
10.2 NMEA Module Planning
The VDR-100G3 base system is composed of 1 NMEA Module for the capture of 8 NMEA
0183/IEC 61162 compatible inputs. A 4 input version and a 4 with VHW (water speed and
heading) version are also available.
In some situations shipboard data sources either have no serial data or generate serial data that
does not meet the IEC 61162 standard. To access these data sources, analog or digital signal
interface units may need to be utilized. These interfaces convert the information from non-
standard data sources into the IEC 61162 data format. The converted data source can then be
connected to any of the serial inputs of the NMEA module for recording.
