Page 7: Introduction
They differ in host interface type, the interface that talks to the computer. Some models also have an NMEA 2000 interface. This manual covers all models of the MiniPlex-3 series. There is a chapter for each type of host port. The remaining part of the manual covers NMEA 0183 and NMEA 2000 connections and configuration, which are the same for all models. -
Page 8: The Multiplexer
Depth Radar Wind Auto- pilot Figure 2 The left part of Figure 2 shows an example: one GPS sends data to four devices. It gets complicated when one device, for example an MFD (Multi-Function Display), needs to receive data from several other devices, as shown in the right part of Figure 2. Unless that MFD has multiple inputs, this is not possible without a multiplexer or combiner. -
Page 9: The Miniplex-3 Multiplexer
The MiniPlex-3 Multiplexer The MiniPlex-3 multiplexer is an advanced NMEA 0183 multiplexer with four NMEA 0183 inputs or listener ports, two NMEA 0183 outputs or talker ports and one or two host interfaces. The MiniPlex-3 combines NMEA 0183 sentences received on its inputs and can route these sentences to its outputs and Host host interface(s). -
Page 10: Nmea 2000 Network Topology
NMEA 2000 Network Topology An NMEA 2000 network has a strict topology: it consists of a backbone cable with terminators at each end and a power-T to provide power to the network. Each device is connected to this backbone using a T, a three-way connector block which is inserted into the backbone and a drop-cable or spur-cable. -
Page 11: The Miniplex-3-N2K Multiplexer
The MiniPlex-3-N2K Multiplexer While NMEA 2000 no longer requires multiplexers to connect devices to each other, a MiniPlex-3-N2K multiplexer still serves a purpose as a gateway between NMEA 0183 and NMEA 2000. Besides being an NMEA 0183 multiplexer providing routing between all NMEA 0183 inputs, outputs and MiniPlex-3-N2K the host interface(s), the MiniPlex-3-N2K also serves Depth... -
Page 12: Host Interfaces
Host Interfaces The following section describe the different types of host interfaces of the MiniPlex-3: USB, Ethernet and WiFi. Each of them requires different steps and knowledge to connect to it successfully. It is very important to read the corresponding paragraphs about the host interface of your MiniPlex-3 carefully to avoid problems. -

To allow our drivers to be loaded, open System Preferences and click on Security & Privacy. On the General tab in this window, enable Mac App Store and identified developers (Figure 16). -
Page 19: Ethernet Interface
Ethernet Interface The MiniPlex-3E(-N2K) has an Ethernet interface to connect it to a network or router. Through this interface, other devices on the network can receive NMEA 0183 data from the MiniPlex-3E and they can send NMEA 0183 data to the MiniPlex-3E. An application connects to the MiniPlex-3E using its IP address and port number 10110. -
Page 20: Direct Connection To A Computer
The only way to get the MiniPlex-3E on the same network is to select the listed MiniPlex-3E and click on Change IP Address. This opens the Assign IP Address window (Figure 18). The MAC Address field already contains the MAC address of the MiniPlex-3E. Enter an IP address that is unique withing your network and click OK. -
Page 21: Udp Mode: Directed
Figure 21 shows an example of fixed IP settings. The protocol is set to UDP. This is the preferred method for NMEA 0183 data. UDP Mode Broadcast ensures that all devices and computers on the same network will be able to receive the NMEA 0183 data. -
Page 22: Network Recovery
Network Recovery If a MiniPlex-3E has a fixed IP address outside the network range or if it doesn’t show up in the search results window due to a possible misconfiguration in the network settings, menu option Tools > MiniPlex-3E > Assign IP can be used to recover from such a situation. -
Page 23: Wifi Interface
WiFi Interface The MiniPlex-3Wi(-N2K) can communicate wirelessly with devices like smartphones, tablets and PCs through its WiFi interface. This WiFi interface provides an access point which other devices can join. A WiFi client is also provided, allowing the MiniPlex-3Wi to join an existing WiFi access point. Connecting to the MiniPlex-3Wi using its WiFi interface requires some basic networking knowledge, which can be found in chapter Network Basics on page 32. -
Page 24: App Behaviour
In your navigation application, you need to enter the IP address of the MiniPlex-3Wi, which is 10.0.0.1. The port number to use is 10110. Figure 24 shows the settings in iNavX ® , for example. Figure 24 The WiFi interface and the USB port of an MiniPlex-3Wi operate simultaneously and with the same priority. -
Page 25: Changing Ssid And Password
Changing SSID and Password The SSID (the network name) and passphrase of the MiniPlex-3Wi network can be changed. Start MPXConfig3 and connect though the USB/COM port. Menu Tools > MiniPlex-3Wi > Setup WiFi Parameters will open a window showing the current WiFi access point settings: Figure 25 The settings shown are the factory-default settings. -
Page 26: Ssid/Passphrase Recovery
Change the SSID and Passphrase as desired and click on the “Sumbit” button which appears at the bottom of the table. The maximum length of the SSID is 32 characters. The password must be 8 to 31 characters. The WiFi interface will restart with the new credentials, and you will need to re-join the WiFi network with these credentials. - Page 27 4. You will see the following web page (Figure 28): Figure 28 5. Click on QuickConnect to go to the WLAN Link Scan page (Figure 29), which shows all the access points found by the MiniPlex-3Wi. Figure 29 6. Click on the access point Name you want to join.

Now you can change IP address into the broadcast address of your existing access point, which is the tricky bit. If the IP address you wrote down in step 12 needs to be changed depending on the number after the slash character.
-
Page 32: Network Basics
Network Basics To understand how a networked MiniPlex-3E or MiniPlex-3Wi works and how to connect to it, some basic knowledge of IP addresses, port numbers and protocols is required. IP Address Every device on a network has a unique number to be able to identify that device. This allows us to send a message to one single device on a network. -
Page 33: Assigning Ip Addresses/Dhcp
Port numbers are not chosen arbitrarily. A certain range is standardized and controlled by an organization called IANA. The MiniPlex-3E uses port number 10110, which is a registered port number for NMEA data. This is the port number you enter in your navigation software. The MiniPlex-3E uses port number 30718 for configuration of the network interface. -
Page 34: Udp Broadcast
UDP Broadcast NMEA sentences are transmitted on the network as UDP messages to the broadcast address. Every device on the network will receive these messages. At the same time, any device on the network can send data to the MiniPlex-3, either to its IP address (directed) or as a broadcast. UDP Broadcast has the following properties: •... -
Page 35: Nmea 0183 Ports
NMEA 0183 Ports The NMEA 0183 ports are the inputs/listener ports and outputs/talker ports of the MiniPlex-3, which connect to NMEA 0183 ports on navigation instruments, chart plotters etc. There are many interpretations and variations of NMEA 0183 ports, so we’ll explain a few things first. NMEA 0183 Signals Although the NMEA 0183 standard specifies the signal names, voltage levels and connection methods very clearly, the reality is far from this ideal world. -
Page 36: Connecting To Other Devices
The default communication speed of the NMEA 0183 outputs is 4800 Baud. Higher speeds up to 57600 Baud (Out1) or 115200 Baud (Out2) can be selected. The speed setting of NMEA Out1 is linked to the speed setting of NMEA In4. When you change the speed of Out1, the speed of In4 will follow. -
Page 37: Seatalk
SeaTalk Port NMEA In1 of the MiniPlex-3 can be switched from NMEA to SeaTalk mode. Thus, NMEA In1 becomes a fully bi-directional SeaTalk port, capable of receiving and transmitting SeaTalk data. This SeaTalk port can be connected to an existing SeaTalk network as shown in Figure 38. SeaTalk NMEA In NMEA Out... -
Page 38: Nmea 2000 Port
NMEA 2000 Port MiniPlex-3 multiplexers with an NMEA 2000 port (the “-N2K” models) can be connected to an NMEA 2000 network or backbone. The MiniPlex-3 can also be connected to a SeaTalk network using a Raymarine SeaTalk to DeviceNet cable (no. A06075). SeaTalk is compatible with NMEA 2000. -
Page 39: Connecting To An Nmea 2000 Network
Connecting to an NMEA 2000 network The MiniPlex-3 is equipped with a standard Micro-C style male connector. Connect the MiniPlex-3 with a spur- or drop-cable and a T-piece to the NMEA 2000 backbone. NMEA 2000 networks must always consist of a powered backbone with terminators, to which the MiniPlex-3 and other devices are connected. -
Page 40: Protocol Conversions
Protocol Conversions The MiniPlex-3 converts navigation data between all three supported protocols – NMEA 0183, NMEA 2000 and SeaTalk – and in all directions. There are subtle differences however in the way each of these conversions work. Knowing these differences can be of great help when adding entries to the routing table. The diagram below (Figure 41) shows how the data flows from one protocol to another. -
Page 41: Seatalk To Nmea 0183
SeaTalk to NMEA 0183 This conversion is controlled by the routing table or the Default Route settings. SeaTalk data is converted into NMEA 0183 sentences, which can then be routed to any NMEA 0183 output or host interface as desired. If no match is found in the routing table or when the routing table is empty, the Default Route is applied. -
Page 42: Power Supply
Power Supply The MiniPlex-3 must be powered from an externally supplied DC voltage from 8 to 35V. The power supply connection is protected against reversed polarity. Indicators The LEDs on the MiniPlex provide information about the status and operation of the MiniPlex-3. When the MiniPlex-3 powers up, all LEDs flash once. - Page 43 The standard speed of an NMEA 0183 port is 4800 Baud or bits per second, representing 480 characters per second (10 bits are needed for one character). It might seem obvious that combining four NMEA 0183 streams at 4800 baud would require the output to be operating at 4 x 4800 = 19200 Baud to prevent any data loss.
-
Page 44: Mpxconfig3
MPXConfig3 The MiniPlex-3 multiplexer is configured with a tool called MPXConfig3. This tool can be found on the accompanying CD and can also be downloaded from the Downloads page on our website. It is available for Windows and macOS. There is no installer for this tool. It can be started directly from the CD or from the downloaded ZIP file or disk image. -
Page 45: Menu
Menu The menu contains two sub-menus: File and Tools. Some options of these menus are disabled or not visible, depending on the type of connected MiniPlex-3 or on the status of the connection. The File menu offers the following choices: Log NMEA…... -
Page 46: Miniplex Connection
MiniPlex Connection Before being able to configure the MiniPlex-3, MPXConfig3 must be connected to the MiniPlex-3. Use the Port selector to select either the COM port of the MiniPlex-3 or TCP or UDP when using a network connection. Do not use UDP All for configuration purposes. COM Port When using a MiniPlex-3 with a USB port, select the COM port that was created after installing the driver. -
Page 47: Socket Error # 10061, Connection Refused
Socket Error # 10061, Connection refused The IP address is correct but the MiniPlex-3E refused the TCP connection. This happens when another application has already opened a TCP connection or when the MiniPlex-3E was configured for UDP. Could not bind socket. Address and port are already in use Another application has already used port 10110 for UDP. -
Page 48: Input Selector
Input selector The input selector allows you to selectively see sentences from one specific NMEA input of the MiniPlex-3, the NMEA 2000 network, conversion results or responses from the multiplexer itself. Overflow The overflow indicators show which output buffer suffers from an overflow. See the chapter Data Throughput on page 42 for ways to prevent overflow situations with different instruments. -
Page 49: Nmea Inputs/Outputs
NMEA Inputs/Outputs This tab contains all settings dealing with inputs and outputs of the MiniPlex-3 and the default routing settings. Each setting is described in detail below. Figure 47 Input Settings Speed This sets the speed of each NMEA 0183 input. 4800 Baud is the standard speed for navigation devices. Some fluxgate or gyrocompasses operate at 9600 Baud to accommodate the higher throughput of 20 headings per second or more. -
Page 50: Priority
Enter the Talker ID in the edit box of the desired input and press the Enter key to send the setting to the multiplexer. A Talker ID should have upper case characters and numbers only. See the Technical Reference section for an overview of the most commonly used Talker IDs. When the Talker ID is changed, the background of the edit field turns yellow to indicate that de modified Talker ID has not yet been sent to the multiplexer. -
Page 51: Input Mode
NMEA 2000 network, the MiniPlex-3 will use this GPS as the source to convert the NMEA 2000 data to NMEA 0183 sentences. When the mast mounted GPS fails or loses fix, the MiniPlex-3 will fall back to using the chart plotter as conversion source. Priorities of NMEA 0183 inputs and NMEA 2000 devices the network can be mixed: the priority value of each NMEA 0183 input is compared directly to the Device Instance of NMEA 2000 data sources. -
Page 52: Input "Nmea 2000
These sentences can be routed using the default route settings and the routing table, using input column C. Conversion results with a different Sentence Formatter originate from the same input as the original sentence. Input “NMEA 2000” NMEA 2000 PGNs are converted into NMEA 0183 sentences, which are processed in the same way as NMEA 0183 sentences received on In1 to In4. -
Page 53: Output Nmea V1.5
If the laptop is not connected, or if no route is activated in the navigation software and it is not transmitting any sentences, the MiniPlex-3 will automatically route sentences from the inputs to Out1, thus allowing the GPS to control the autopilot. Output NMEA V1.5 NMEA Out2 has an option to convert specific sentences from NMEA 0183 V2.0 and up to V1.5 format. -
Page 54: Options
Options On this tab, several options can be enabled as well as NMEA 0183 sentences that are generated from NMEA 2000 and SeaTalk. Figure 49 General Options AIS MOB Alarm The MiniPlex-3 has an AIS MOB alarm feature, which responds to AIS-SART messages from AIS-based SART, MOB and EPIRB devices. -
Page 55: Suppress Pinning
Suppress Pinning Modern GPS receivers may not transmit course over ground and even speed over ground when the GPS is not moving. This is called pinning. When a GPS is stationary, a COG cannot be determined, thus it has a random value while the SOG might be either 0 or a very small but varying value. Pinning suppresses these random values by marking the data as “not available”... -
Page 56: Vbw/Vhw (Speed
if the System Time was received from an NMEA 0183 RMC or ZDA sentence, the MiniPlex will only transmit the System Time on NMEA 2000 and SeaTalk. The priority of the System time in case of multiple sources is, in descending order, NMEA 2000 > NMEA 0183 >... -
Page 57: Conversions
Conversions The MiniPlex-3 can convert certain NMEA 0183 sentences into new sentences. These can be sentences received on inputs 1 to 4 or sentences created from an NMEA 2000 or SeaTalk source. The original sentence remains unaffected, a conversion always creates a new additional NMEA 0183 sentence. When the address field of the converted sentence is identical with the original sentence, like a reversed true heading (HDT à... -
Page 58: Hdt Ssà Ths
HDT ßà THS This option converts an HDT sentence into a THS sentence and vice versa. The Talker ID in HDT and THS sentences is preserved to ensure compatibility with GPS compasses, which generally output a Talker ID “GP”. The resulting conversion originates from the same source as its original. Speed GPS Speed to Log Speed (VTG à... -
Page 59: Routing
Routing The routing table is the most powerful feature of the MiniPlex-3. It allows NMEA 0183 sentences to be filtered and routed based on their Address Field and source, and optionally reduce their rate or frequency when routed to one of the NMEA 0183 outputs. The routing table stores up to 50 entries, either entered manually or by capturing the NMEA 0183 sentences received/generated by the multiplexer. -
Page 60: Routing Table Columns
Routing Table Columns The routing table contains the following columns: Index: The leftmost column is the entry number. Clicking on a number enables the Delete button to delete the entry. Inputs: 1-4: NMEA 0183 inputs 1 to 4. If In 1 is set to SeaTalk, the “1” changes into “ST” NMEA 0183 Conversion results Input from the Host port(s) Input from the NMEA 2000 port... -
Page 61: Editing The Table
Editing the table It is important to keep in mind that all modifications and additions are made to the routing table in MPXConfig3 only. The current table is automatically loaded from the MiniPlex-3 to MPXConfig3 when you connect to the MiniPlex-3 or when you click on the Read Configuration button. After editing, the table must be stored in the MiniPlex-3 using the Store button to be effective. -
Page 62: Nmea 2000 Sources
NMEA 2000 Sources A checkbox in the N column and an empty Device field will pass that sentence from every device on the NMEA 2000 network. Using only the checkbox is sufficient in case of a single source of each sentence. When multiple sources of the same sentence exist, use the Device field to select the source of that sentence. -
Page 63: Example
• Conversions are applied after filtering. As a result, sentences that are blocked on an input will not be converted. This implies that if a sentence must be converted and only the conversion result is required, the originating sentence must be enabled on the receiving input and blocked on all outputs. -
Page 64: Nmea 2000
NMEA 2000 In general, it is not necessary to change any of the settings on this tab. If all devices on the NMEA 2000 network receive the converted NMEA 0183 from the MiniPlex-3, everything is just fine. The MiniPlex-3 announces itself on an NMEA 2000 as six virtual devices: one Main device, and one device for each NMEA 0183/SeaTalk input and the conversion results. -
Page 65: Sa (Source Address)
Some Device Types are marked with “(< V2)”. In the transition from V1.300 to V2.000 of the NMEA 2000 standard, some Device Class and Device Function codes were changed. Older devices supporting NMEA 2000 V1.300 may therefore not recognize V2.000 Device Class and Device Function codes. The “(<... -
Page 66: From All Pgns
From all PGNs When this option is enabled, the conversion from NMEA 2000 PGNs to NMEA 0183 sentences is completely disabled and every received NMEA 2000 PGN is converted into one or more sentences. $MXPGN This allows software on a PC to read and decode every possible NMEA 2000 PGN. It is also possible to send an sentence to the MiniPlex-3 using an NMEA 0183 input or host $MXPGN... -
Page 67: Device Instance
There is one case in which setting a Source Address is required: On a Raymarine SeaTalk network, Source Addresses are used to determine the priority of a data source: a higher Source Address implies a higher priority of the data source. When a fast or high precision heading sensor with an NMEA 0183 output is connected to a SeaTalk network through a MiniPlex-3 (or any other NMEA 0183/2000 gateway), A Raymarine autopilot system will generally ignore this heading source and use the heading source of the autopilot system instead. -
Page 68: Ais Mob Alarm
AIS MOB Alarm The MiniPlex-3 AIS MOB alarm responds to “AIS SART” messages from AIS-based SART, MOB and EPIRB devices. To receive these AIS-SART messages, an AIS transponder or receiver must be connected to the MiniPlex-3, either via NMEA 0183 or NMEA 2000. The AIS MOB alarm will only trigger on devices listed in the table. -
Page 69: Connections
Connections To be able to use the AIS MOB Alarm, the following connections need to be made (see Figure 62): • A momentary push-button connected to a 12/24V source and NMEA Input 4 • A buzzer connected to the Switch A/B contacts and 12/24V Note that the Switch A/B contacts are rated at 60V/0.6A max, for resistive loads only. - Page 70 it will start transmitting. With clear satellite visibility, this should take no more than one minute. A GPS fix will most likely be indicated by a LED changing state. In this case, wait for the GPS fix to occur, then press and hold the Acknowledge/Control switch to enable Learning Mode on the MiniPlex.
-
Page 71: Modbus
Modbus Modbus is an industrial protocol, used to read data from multiple (industrial) sensors on a single RS485 network. Modbus enabled sensors typically measure non-navigation-related physical quantities like temperature, pressure, level or flow. When Modbus is enabled, the MiniPlex-3 becomes a Modbus master, utilizing the Modbus-RTU protocol via port NMEA Out2. -
Page 72: Modbus Slave Addresses
Modbus Slave Addresses The MiniPlex-3 uses Modbus protocol addresses (0-based) and a specified register type, as opposed to PLC addresses (1-based), where the register type is implied by the register number. The Holding register range from 0 to 9998 corresponds with a PLC address range from 40001 to 49999 whereas the Input register range from 0 to 9998 corresponds with a PLC address range from 30001 to 39999. -
Page 73: Firmware Update
Firmware Update Firmware updates with new features or bug fixes will be available through our web site. These firmware files can be downloaded to your computer and loaded into the MiniPlex-3 using menu File > Update MiniPlex Firmware. MPXConfig3 also contains MiniPlex firmware, which is embedded in the application. This firmware is the minimum required version that is compatible with this version of MPXConfig3. -
Page 74: Mounting
Mounting The MiniPlex-3 is not waterproof. It should be mounted at a dry place such as behind the instrument panel on a flat surface. Make sure there is enough space around the MiniPlex-3 to connect the NMEA 0183 wiring at the bottom, the NMEA 2000 connector on the left side and USB/Network connector on the right side of the housing. -
