10 NMEA MODULE

10.1

Introduction

The NMEA Module provides a connection to all IMO-required data in both NMEA 0183/IEC
61162 and limited ASCII data formats. The NMEA module multiplexes up to 8 NMEA-0183 data
streams from shipboard systems onto an RS-232/422 serial data channel, and at the same time
onto an Ethernet connection (UDP). The captured data is sent to the DMM via an Ethernet
connection for storage and retrieval.
These modules use embedded microprocessor technology with real-time buffer storage to handle
data from multiple channels at the same time. In addition:
Data is handled on a first-in-first-out basis, assembled, and then transmitted via the serial
output port to the receiving computer or data logger; and
An efficient anti-collision algorithm preserves the integrity of the data even at high
incoming data rates.
The NMEA module is integrated into the Data Acquisition Unit of the VDR-
100G3, but
The optional remotely mounted NMEA module must be specified when the
VDR-100G3 is ordered.
