Shipmodul Miniplex-3E N2K

The MiniPlex-3E 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-2E multiplexer has some major advantages:

  • Data from multiple instruments is available as one single stream on the Ethernet network. This reduces wiring cost and the data is available to any device or computer on the network.
  • Supports TCP/IP for a point-to-point connection and UDP Broadcast to communicate simultaneously with all computers and devices on the network.
  • All computers and devices can send data to the MiniPlex−2E.
  • Seamless integration into an existing Raymarine Seatalk® network.
  • All inputs are galvanically isolated, eliminating ground loops between instruments.
  • Full galvanic isolation on the Ethernet port, eliminating ground loops between multiplexer and network.
  • 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 firmware inside the MiniPlex−3E can be updated over the network. This can also be done remotely over the Internet. Updated firmware files are available on the Download page.

Features

The MiniPlex-3E has a rich set of features and configuration options, enabling the user to tackle almost any NMEA bottleneck or interface problem. The supplied Windows utility  MPX-Config  allows full configuration of the multiplexer and monitoring of NMEA data passing through the multiplexer. 

NMEA routing NMEA data can be routed from any input to any output. A default route can be set as well as specific routing rules for individual NMEA sentences.
Network data can be routed to any NMEA output, to be merged with other NMEA data or to override this data. This enables automatic switching between computer based navigation and GPS/instrument based navigation.
NMEA filtering A flexible NMEA filter can be configured to pass or block specific sentences from each input channel. This greatly reduces the chance of an overflow and the resulting loss of data. Many GPS receivers for instance, transmit an abundance of sentences every second, accounting for 85% of the available bandwidth of the NMEA channel. By blocking unwanted or unnecessary sentences, bandwidth is preserved for other instruments. The filter can also be configured to reduce the rate of specific NMEA sentences.
Flexible communication speed The communication speed of all inputs and outputs can be set from 4800 to 57600 Baud to allow connection of devices that operate at non-standard (4800 Baud) communication speeds like integrated weather sensors, gyrocompasses orAIS equipment.
SeaTalk® conversion When the SeaTalk -> 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.
Real-Time forwarding Gyro- and fluxgate compasses produce NMEA sentences at a high rate (10 sentences/second or more). This can lead to a buffer overflow in the multiplexer. Although this overflow is handled properly without data corruption, it will lead to a delay of NMEA sentences of up to 20 seconds in extreme situations. This produces a severe problem for autopilots, which cannot make proper course corrections when their heading feedback is delayed for 20 seconds. The Real-Time option prevents this delay by bypassing the buffer of that specific channel and forwarding the data immediately to the multiplexer's NMEA output. As a result, the heading is never delayed more than 0.2 to 0.5 seconds, depending on the amount of other NMEA sentences passing through the multiplexer.
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. The Ethernet port has the highest priority, followed by inputs 1 to 4, in descending order. When for instance 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.
Channel information When this feature is switched on, the multiplexer will transmit a proprietary NMEA sentence indicating on which input channel the following NMEA sentence is received. Optionally, the multiplexer can append NMEA V4.0 TAG block to each NMEA sentence to indicate its originating input.
Talker ID substitution Talker ID substitution changes the talker ID of incoming sentences. The talker ID can be specified for each input channel. This option is useful for software or instruments that expect a specific talker ID or to distinguish between sentences from two similar instruments.
