PRO-MUX-1 Professional NMEA 0183 Multiplexer
The Actisense® PRO-MUX-1 is a robust and highly flexible platform that cures many interconnectivity headaches.
The PRO-MUX-1 is reliable, robust and provides industry leading isolation on all inputs and outputs as standard, so that connected devices safely avoid hazardous ground loops, the number 1 cause of product failure in NMEA 0183 networks.
The eight NMEA 0183 inputs can be routed to any of the six NMEA 0183 outputs, providing a highly customisable network. A bi-directional serial port and an Ethernet port allow for simple configuration and diagnostics using Actisense software.

The configuration tool is accessible via any popular web browser (using the Ethernet port) so there are no PC operating system compatibility issues to contend with. Using the web based configuration tool will allow the user to finely tune the exact data available on each output. The default setup is for all data to go to all outputs.

2-part pluggable connectors on the PRO-MUX-1 (screw or screwless terminals available) mean that new devices can easily be installed without the need to remove the PRO-MUX-1 from its mounted location. A professional DIN rail mounting mechanism keeps the PRO-MUX-1 secure in high vibration environments. Helpful LEDs indicate power, data in, data out and the alarm status to aid diagnostics.
