UNICONT MCA BC COT 2-2003/1 MACCA BC2190605-046 NMEA AMPLIFIER /MULTIPLIER

The UNICONT MDU-102 is a marine-grade electronic device designed to solve a common problem onboard: distributing navigational data from one or two sources (like a GPS) to multiple instruments (like chart plotters, autopilots, and displays) without signal degradation. It acts as a powerful signal multiplier and amplifier for NMEA 0183 data.

Key Features & Functionality

  • Signal Multiplication: It can take a single NMEA 0183 input and create multiple, identical outputs, allowing you to connect several receiving devices to one talker.

  • Dual Inputs: The unit features two input ports, allowing it to receive and distribute data from two separate sources.

  • Checksum Testing: It performs a checksum test on data received on the first channel, which helps ensure data integrity.

  • Versatile Outputs: The MDU-102 provides a total of 8 output ports, organized into two groups ("A" and "B") of four ports each. This provides substantial capacity for connecting multiple instruments.

Applications

This amplifier/multiplier is ideally suited for distributing NMEA data from a primary navigation source (e.g., GPS, gyrocompass) to multiple displays, autopilots, AIS, and other marine electronics within a vessel's network. It is a core component for data distribution in modern marine electronics systems.
