The converter is designed to receive, combine, convert and multiply NMEA 0183 messages transmitted over RS-422, RS-485, Ethernet and USB interfaces, with a configurable operating algorithm.

The converter has one Ethernet interface (UDP unicast/multicast), one USB interface, and six isolated RS-422/RS-485 serial interfaces (four of which are universal and can be configured for both input and output).

The converter consumes less than 7 W and has a wide supply voltage range (9.5 to 36.0 VDC) as well as overvoltage protection and reverse polarity power connections.

The converter is housed in a compact IP22-rated metal enclosure and mounted on a mounting plate. The wide operating temperature range (-15 to +55 °C) allows the converter to be used in harsh environments and unheated rooms.

  • redirection of flows;
  • duplication of messages;
  • decreasing/increasing frequency of message transmission;
  • filtering of messages by header;
  • message transmission with header substitution;
  • message transmission with conversion of the numeric value of the input message field;
  • organization of input channels redundancy;
  • adding / changing IEC 61162-450 tags;
  • message multiplexing.

How it works

MFC-151 processes data received from multiple inputs. Data processing is defined by a user-created schema using a unique MFC Studio utility.


Multiport ................................. 1 to 6 serial inputs with Ethernet pass-through to a virtual COM port

Multiplexer & LAN .......... 2 inputs → 4 outputs with Ethernet redundancy

Multiprexor → LAN .......... 1 to 6 inputs with data transfer to the network

Flexible setup ..................... changing speed, frequency, filtering and data transfer/reception to the network

MFC Studio software is used to set up the converter. With MFC Studio, the user can easily create projects using ready-made blocks in various combinations as well as load projects into and out of the converter.

  1. Select the desired item:
  2. Drag and drop elements onto the schematic and connect them
    • inputs
    • outputs
