Actisense products are intended for use in a marine environment, primarily for below deck use. If a product is to be used in a more severe environment, such use may be considered misuse under the Active Research Ltd guarantee.
Warning 1: Accuracy The Actisense PRO-MUX-1 is designed to accurately transfer data from input to output. When the PRO-MUX-1 is in a Basic Mode no data integrity checking is performed, therefore any incomplete, inaccurate or corrupt data received on a PRO-MUX-1 input will be duplicated to the PRO-MUX-1 outputs.
Professional NMEA 0183 Intelligent Multiplexer - PRO-MUX-1 PRO-MUX-1 Intro & Features The Actisense® Professional NMEA 0183 Multiplexer (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.
Before getting started The wire colours used in this manual are in accordance with the NMEA 0183 specification (v.4.10, June 2014) and are for illustration purposes only. Please ensure you check the wiring colours in the installation instructions for the devices you wish to interface to the PRO-MUX-1. Terminals The PRO-MUX-1 comes with two main choices for its 2-way and 3-way connectors: ‘screw’...
Professional NMEA 0183 Intelligent Multiplexer - PRO-MUX-1 NMEA 0183 Talker and Listener Designations The NMEA have updated the NMEA 0183 specification to ensure a consistent naming convention is used for labelling ports. The designation follows the same rules as used for Rx and Tx labelling but uses Talker and Listener instead.
Serial The connections for a standard RS232 cable are: NDC-5 Label Serial Serial Serial Connects to DB9 Pin 3 / Pin 5 / Pin 2 / Serial Port Ethernet Either a standard Ethernet patch or crossover cable with an RJ45 plug can be used for a direct connection to a PC/laptop, or the PRO-MUX-1 can be connected to an Ethernet network switch.
Latch down Bulkhead Mounting Actisense recommends the PRO-MUX-1 is installed using the DIN rail supplied for the most secure installation. However, the PRO-MUX-1 can be secured to a bulkhead using the two screw catches on the reverse of the PRO-MUX-1 shown in the diagram below.
Web Browser Configuration Tool The Configuration Tool for the PRO-MUX-1 is built-in and can be accessed via the Ethernet connection. As the Configuration Tool is web based it is compatible with all popular web browsers and Operating Systems. An internet connection is not required to access the Configuration Tool. The default page displayed is the PRO-MUX-1 Configuration Tool ‘Home’...
Professional NMEA 0183 Intelligent Multiplexer - PRO-MUX-1 Direct connections or basic Ethernet networks If the PRO-MUX-1 is connected directly to a PC (or the Ethernet network does not have a DHCP server), the PRO-MUX-1 will communicate using auto-IP by default. The auto-IP process can take up to 60 seconds to complete.
Troubleshooting Guide First level PRO-MUX-1 diagnostics / fault finding can be performed by observing the LED behavior. The normal behavior of the PRO-MUX-1 LEDs is described on the next page. If the LEDs are not behaving as expected, this will indicate a fault in either the device connected to the PRO-MUX-1, the wiring/ connections, or the PRO-MUX-1 itself.
All installation instructions and any warnings contained in this manual must be followed before contacting Actisense technical support. If the troubleshooting guide did not help resolve the problem and an error persists, please contact Actisense Technical Support to help trace the issue before considering the return of the product.
