Actisense – The Award-Winning NMEA Specialists

Actisense aim to be the installer’s product of choice by making navigation safer with the most reliable boat electronic systems. Based in Poole, Dorset on the south coast of England, Active Research Limited has established an enviable world-wide reputation within the specialist field of marine electronics. This has been achieved by providing an excellent level of service to our extensive client base and through the design and manufacture of prestigious marine electronic equipment.

Actisense The PRO Range : PRO-BUF-1 and PRO-MUX-1

PRO-BUF-1: Adaptable NMEA 0183 Buffer with a variety of operating modes. Provides two OPTO-isolated inputs and twelve ISO-Drive™ outputs, keeping devices safe from hazardous ground loops. PRO-BUF-1 is reliable, robust and provides isolation on all inputs and outputs as standard. With two NMEA 0183 inputs, twelve NMEA 0183 outputs, a bi-directional serial port and an Ethernet port, the PRO-BUF-1 is a perfect solution for larger leisure vessels and commercial shipping. The PRO-BUF-1 is designed to suit the majority of NMEA 0183 systems and ready to go ‘out of the box’ by simply hard-wiring the two mode inputs as required. The manually configurable basic modes of operation include variations of buffer modes, autoswitch modes, and combine modes. For all other configurations, leaving the mode inputs floating selects the ‘User Configuration Mode’. The web browser based configuration tool allows full customisation of the PRO-BUF-1, and is compatible across all popular Operating Systems. The PRO-BUF-1 supports a direct Ethernet connection to a PC without the need for a specialised Ethernet crossover cable.

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.

Actisense NMEA 0183 Range : NBF-3, NDC-5 and USG-2

NBF-3: The Actisense NMEA 0183 Buffer isolates and buffers NMEA 0183 data, with the power to drive multiple devices. You can safely connect to 6 NMEA 0183 Listeners to the NBF-3 with complete peace of mind that your devices are safe from hazardous ground loops. The OPTO-isolated input also protects the connected Talker. NBF-3 distributes up to six identical, amplified streams of data from one source. The NMEA signals are buffered to ensure that each Listener receives the data at the required voltage levels, providing consistent data quality. The NBF-3 has the addition of power distribution for the NMEA Talker.

NDC-5 Multiplexer: The five NMEA 0183 inputs can be routed to any of the two NMEA 0183 outputs providing a highly customisable network. The bi-directional serial port and Ethernet port also allow for simple configuration and diagnostics using Actisense software. The configuration tool is accessible via any popular web browser so there are no PC operating system compatibility issues to contend with. Industry leading isolation is provided on all inputs and outputs as standard, so that connected devices safely avoid hazardous ground loops, the number one cause of product failure in NMEA 0183 networks. This makes the NDC-5 robust enough to handle any NMEA 0183 installation. Pluggable connectors allow new devices to be easily installed without the need to remove the NDC-5 from its mounted location. 

USG-2: Advanced technology for safe, reliable and simple connection of your NMEA 0183 devices to your PC’s USB port. The USG-2 converts a USB port into a bi-directional serial port suitable for connecting to a marine standard NMEA 0183 data bus. Electrical isolation is provided by the ISO-DriveTM output and OPTO-isolated input making installation simple and free from ground loops and far safer connection when compared to standard USB to serial converters. Multiple LEDs make diagnosing connection issues quick and easy. The blue power LED Illuminates solid blue when the USB driver has successfully loaded and the USG-2 is powered, while a green (receive) LED and an orange (transmit) LED indicate whether data is present. The pluggable screwless connector makes installation quick and easy, and the specifically designed DIN rail mount option ensures a reliable secure bulkhead mount for the USG-2.

The NMEA Range: 

The Actisense EMU-1 is a specialised analogue to NMEA 2000 Gateway which converts data from analogue engine gauges/senders into NMEA 2000 data. The EMU-1 can monitor vital engine parameters such as temperature, pressure RPM and fluid levels from up to two engines. The EMU-1 has a PC based configuration tool that allows the settings inside the EMU-1 to be changed to best suit the engine it is working with, making it a flexible solution for many engine makes and models. Please see downloads section for full details.

The Actisense NGT-1 is the only intelligent NMEA 2000 gateway available to precisely transfer messages to and from the NMEA 2000 bus. The diagnostic NMEA Reader software allows viewing of NMEA 2000 messages with configuration options, enabling the set-up of all Actisense products on the NMEA 2000 bus.
The NGT-1 is available in two versions:
NGT-1-USB is the standard option – USB interface for bi-directional connection to a PC.
NGT-1-ISO is a more specialist option – Opto-isolated input and ISO-Drive output for a direct PC bi-directional connection.
Both versions are available with the SeaTalkNG to NMEA 2000 adaptor Cable – STNG-A06045 

The Actisense NGW-1 NMEA 2000 Gateway is the easiest way to link between a boats old and new data networks. The NGW-1 can convert NMEA 0183 data into NMEA 2000 data and vice-versa. The NGW-1 is available to purchase in a variety of options:
NGW-1-ISO is the standard option. With an opto-isolated input and ISO-Drive output for direct NMEA 0183 device bi-directional connection.
NGW-1-ISO-AIS is the NMEA 0183 AIS option that enables the conversion of NMEA 0183 AIS data to its equivalent in NMEA 2000. This provides an ‘out of the box’ solution for quick installation with no configuration required.
NGW-1-USB is the NMEA 0183 USB (1.1 and 2.0) interface for bi-directional connection to a PC for use with NMEA 0183 software. Every option of the NGW-1 is available with the SeaTalkNG to NMEA 2000 adaptor Cable – STNG-A06045. 

The NMEA Network Range and Cabling

The Actisense range of NMEA 2000 connectors and cables has been designed using our specialist interconnect and NMEA knowledge. There are nultiple cables and connectors to provide a large range of solutions to your onboard requirements. A few examples are:

NMEA Starter Kit: A2K-KIT-1 and the kit contains:
A2K-MPT-1 Micro Power T – to power the network
A2K-TER-F NMEA 2000 micro terminator female – to terminate one end of the network
A2K-TER-M NMEA 2000 micro terminator male – to terminate the other end of the network
A2K-T-MFF 2 x Micro T Piece – to allow two NMEA 2000 devices to connect to the network
A2K-TDC-2M NMEA 2000 Lite cable assembly 2 metre – to extend the distance between any two network pieces

NMEA Small Boat Network: A2K-SBN – The equivalent of four T-pieces in a single case provides a significant time and space saving with no more connecting multiple T-pieces together. Termination resistors are built in which increases the saving on time and space. Once the attached 3 metre cable is connected to the boats power supply, an NMEA 2000 network for up to four devices is ready to use, taking ‘plug & play’ to the next level.
