1.1.5 NMEA Input Modules
The
NMEA Input Modules
provide connection to all IMO-required data items in both NMEA 0183/IEC
61162 and limited ASCII data formats. NMEA modules multiplex up to eight (8) NMEA-0183 data
streams from shipboard systems onto a single RS-232/422 serial data channel, and simultaneously on an
Ethernet connection (UDP). Captured data is sent to the DMM via an Ethernet connection for storage
and eventual retrieval.
These modules use embedded microprocessor technology with real-time buffer storage to handle
simultaneous arrival of data on multiple channels without conflict. Additionally:
ƒ
An efficient anti-collision algorithm preserves the integrity of the data even at high incoming data
rates.
ƒ
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.
