MiniPlex-2S Serial 4 Ch NMEA Multiplexer
Part #1120
MFG #1120-MINIPLEX-2S
The MiniPlex-2S is an advanced NMEA multiplexer, combining data from up to four navigation instruments into two NMEA outputs and an RS–232 port. It also supports AIS and other high speed NMEA devices up to 57600 Baud.
Using the MiniPlex–2S multiplexer has some major advantages:
• Data from multiple instruments is available as one single stream on one single cable. This reduces wiring cost.
• Seamless integration into an existing Raymarine Seatalk® network.
• All inputs are galvanically isolated, eliminating ground loops between instruments.
• Full galvanic isolation on the RS-232 port, eliminating ground loops between multiplexer and computer which
are often on separate power grids.
• The MiniPlex allows you to fully control the source, the destination and the rate of each individual NMEA
sentence by its powerful sentence filtering and routing facility.
• Automatic switching between computer navigation and GPS based navigation.
• Automatic switching between primary and secondary instruments in case of failure or invalid data.
Two NMEA outputs (talker ports) allow distribution of the NMEA data to up to eight instruments. The MiniPlex-2S can be connected to a computer through the galvanically isolated RS-232 interface for computerized navigation. Stand-alone operation is also possible, in which case the RS-232 interface is only used to configure the multiplexer.
SeaTalk® conversion – When the SeaTalk to NMEA option is enabled, one of the NMEA inputs becomes a SeaTalk® compatible input, offering conversion of the most common SeaTalk datagrams on a Raymarine® network into NMEA sentences. This data is combined with NMEA data received on the other inputs. When Priority is enabled, SeaTalk® data can be assigned highest or lowest priority.
Heading conversion – This option converts a Magnetic Heading sentence (HDG) into a True Heading sentence (HDT). If the originating magnetic heading sentence contains a magnetic variation, it is used to calculate the true heading before conversion. This feature is useful for certain equipment like VDR’s which need a true heading input, while the only available heading source is a fluxgate, delivering a magnetic heading.
Priority - With Priority enabled, similar NMEA sentences on different inputs are only passed from the input with the highest priority. For instance, when two GPS receivers are connected to inputs 1 and 2, and both transmit the same type of NMEA sentences, only those received on input 1 are passed. An adjustable time-out ensures that similar sentences from the GPS at input 2 are passed when the GPS at input 1 stops sending these sentences. Optionally, GPS sentences are checked for a valid status field, causing automatic switchover when the primary GPS looses satellite signal.
