NMEA multiplexer

Split one NMEA source to multiple survey and vessel systems

Data Mirror provides a software alternative to NMEA multiplexers, splitters, and repeaters for offshore and marine operations.

Operational problem

Why this matters offshore

A single GNSS or INS source is often required by acquisition, navigation, logging, and display systems at the same time.

Data Mirror outcome

Software routing without extra hardware

Mirror one NMEA input to many outputs, monitor the live terminal stream, and reconfigure routes without changing vessel infrastructure.

Common use cases
GNSS to multiple acquisition applications
Survey vessel integration
Temporary mobilisation routing
NMEA repeater software for downstream displays
GNSS to survey and navigation systems
GNSS to multiple acquisition applications
INS data distribution
Vessel telemetry replication
Binary sensor protocol routing
Terminal, console, and logging

Inspect UDP, TCP, serial, ASCII, and binary data while routing it

Data Mirror combines routing with practical terminal, console, command, and logging workflows for offshore setup, integration, and fault-finding.

UDP terminal and logging

View UDP packets in a live terminal, send test commands or configuration messages where the device supports them, and keep logs for troubleshooting survey or vessel telemetry feeds.

TCP console and diagnostics

Inspect TCP streams from networked marine systems, send console commands to connected devices, and route the same feed to downstream applications.

Serial terminal for RS232 feeds

Use Data Mirror as a serial terminal for RS232-style data, including command entry, NMEA inspection, and custom ASCII stream logging.

Operational route logs

Capture routing evidence during mobilisation, integration, and offshore fault-finding without adding separate terminal tools.

Binary protocol routing

Route binary data protocols and proprietary sensor streams over UDP, TCP, or serial links without converting them to text first.

Protocols and streams

Route text and binary data over UDP, TCP, and serial links

Data Mirror routes marine data streams without forcing them through a hardware splitter or protocol converter first.
